When Should UK Authors Use IngramSpark Instead of Amazon KDP?

Amazon Kindle Direct Publishing and IngramSpark both allow independent authors to publish print-on-demand books, but they are designed around different distribution strengths.

KDP provides direct access to Amazon’s retail ecosystem. It allows authors to publish Kindle eBooks, paperbacks and hardbacks, manage Amazon product pages and use Amazon-specific promotional tools. IngramSpark focuses more heavily on wholesale and global distribution to retailers, bookshops, libraries and other trade partners.

The IngramSpark vs Amazon KDP for UK decision should therefore begin with the author’s intended sales channels.

KDP may be sufficient when most readers are expected to order through Amazon. IngramSpark may be more suitable when the author wants the book to appear in wholesale catalogues used by independent bookshops, library suppliers and international retailers.

Many authors do not need to choose only one. A carefully planned publishing setup can use KDP for direct Amazon print sales and IngramSpark for wider trade distribution. This arrangement requires the author to own the ISBN, maintain identical metadata and avoid conflicting distribution settings.

Neither platform guarantees that a physical bookshop will place the book on its shelves. Distribution makes a title available to order. Stocking decisions still depend on demand, commercial terms, production quality and the individual retailer or library.

What Is Amazon KDP?

Amazon KDP is Amazon’s self-publishing platform.

It supports:

• Kindle eBooks
• Print-on-demand paperbacks
• Print-on-demand hardbacks
• Amazon marketplace distribution
• Author copies and proof copies
• Kindle Unlimited through KDP Select
• Amazon advertising
• Amazon Author Central
• Amazon A+ Content
• Series pages
• Sales and royalty reporting

Authors upload their manuscript, cover and metadata, then select pricing and distribution territories. Amazon prints paperback and hardback copies when customers order them, reducing the need for the author to purchase and store a large inventory.

KDP is particularly convenient for authors whose main sales are expected to come through Amazon.co.uk or other Amazon stores.

What Is IngramSpark?

IngramSpark is a self-publishing and print-distribution service operated within the wider Ingram publishing and wholesale network.

It supports:

• Print-on-demand paperbacks
• Hardbacks
• eBooks
• Global wholesale distribution
• Retailer ordering
• Library-channel availability
• Publisher-controlled ISBNs
• Wholesale discounts
• Returns settings
• International print and distribution options

IngramSpark makes print and digital titles available through a broad network of retailers, libraries, online shops and distribution partners. Its print-on-demand system is connected with Ingram’s established wholesale relationships, helping books become available through trade channels beyond one retail platform.

The platform is often considered by authors who want their books to be commercially orderable through the systems used by independent bookshops and libraries.

The Main Difference Between KDP and IngramSpark

The main distinction is not simply printing quality or upload convenience.

It is the route through which the book reaches the customer.

KDP’s Primary Strength

KDP is closely connected with Amazon.

An author can publish directly into Amazon’s system, where the book may benefit from:

• Direct Amazon availability
• Faster Amazon listing updates
• Amazon-focused print fulfilment
• Kindle publishing
• Kindle Unlimited eligibility for enrolled eBooks
• Amazon Advertising
• A+ Content
• Author Central
• Amazon sales reporting

IngramSpark’s Primary Strength

IngramSpark is designed around wider wholesale distribution.

It can make books available to:

• Independent bookshops
• Online retailers
• Library suppliers
• Academic institutions
• International trade partners
• Retail and library eBook channels

IngramSpark’s distribution network does not guarantee that these organisations will order the book. It removes a major practical barrier by allowing trade customers to find and order the title through recognised systems.

Use IngramSpark When Bookshop Distribution Matters

An author should consider IngramSpark when independent bookshops are an important part of the publishing strategy.

Many bookshops prefer to order from wholesalers already connected with their stock, invoicing and returns systems.

A shop may hesitate to order directly from:

• An individual author
• Amazon
• An unfamiliar print service
• A website without trade invoicing
• A supplier offering no returns
• A book with no wholesale discount

IngramSpark allows the publisher to set wholesale terms and decide whether the book is returnable. These settings can influence whether a retailer is willing to consider the title. IngramSpark notes that many physical bookshops are reluctant to order books that cannot be returned, although enabling returns creates a financial risk for the publisher.

Trade availability is only the first step.

Bookshops may also consider:

• Local demand
• Cover design
• Retail price
• Genre
• Reviews
• Author events
• Sales history
• Marketing support
• Shelf space
• Comparable titles

IngramSpark can make the transaction easier, but the author must still create a convincing commercial case.

Use IngramSpark When Libraries Are a Priority

Authors researching how to get self published book into UK libraries may find IngramSpark more suitable than an Amazon-only setup.

Public libraries commonly obtain stock through contracted suppliers and wholesale systems. They may be unable or unwilling to order directly from an author’s Amazon page.

A library-ready title generally needs:

• Valid ISBN
• Accurate metadata
• Professional cover
• Suitable physical format
• Reliable supplier availability
• Competitive retail price
• Clear subject categories
• Credible reviews
• Evidence of reader or local demand

KDP does offer Expanded Distribution for eligible paperbacks, potentially making them available to distributors serving bookshops, libraries and academic institutions. Amazon makes clear, however, that Expanded Distribution does not guarantee acceptance by a distributor or an order from any library or bookseller. Expanded Distribution is also unavailable for KDP hardbacks.

IngramSpark may give authors more direct control over the wholesale terms used to present the book to trade buyers.

Use IngramSpark When Publishing Hardbacks for the Trade

KDP supports hardback publishing, but KDP Expanded Distribution is not available for hardback editions. KDP hardbacks can still be sold through supported Amazon marketplaces, but the platform does not extend those editions through its Expanded Distribution programme.

IngramSpark may therefore be a stronger choice when the author wants a hardback to be orderable through:

• Independent bookshops
• Library suppliers
• Specialist retailers
• Academic buyers
• International wholesalers

This can be relevant for:

• Gift books
• Illustrated nonfiction
• Premium editions
• History
• Biography
• Children’s books
• Reference books
• Institutional publications

The author should still compare available trim sizes, binding choices, printing costs and expected retail prices before committing to a format.

Use IngramSpark When International Trade Reach Matters

An author may have readers in several countries or may publish a subject with international appeal.

Examples include:

• Migration history
• Academic or professional nonfiction
• International business
• Religious books
• Diaspora literature
• English-language fiction
• Travel
• Education
• Specialist reference

IngramSpark combines print-on-demand production with international distribution relationships, allowing eligible titles to be printed or supplied through different markets.

KDP also distributes through multiple Amazon marketplaces, so international Amazon sales do not require IngramSpark automatically.

The distinction is whether the author needs:

• Amazon availability in several countries
• Wider non-Amazon trade availability
• International library and retailer channels
• Local wholesale ordering
• Broader eBook distribution

Authors should identify where their readers actually buy books before paying for a distribution structure they may not use.

Use IngramSpark When You Want Your Own Imprint

KDP offers free ISBNs for eligible paperbacks and hardbacks. A free KDP ISBN can be used only through KDP, and the public imprint is registered as “Independently published”.

Authors who want to publish under their own imprint should purchase ISBNs from the appropriate national agency.

A UK publisher normally obtains ISBNs through the Nielsen UK ISBN Agency.

Owning the ISBN allows the author or publishing business to:

• Register its own imprint
• Use the same ISBN through more than one compatible print service
• Control bibliographic identity
• Build a consistent publishing catalogue
• Publish future editions under the same business
• Avoid platform-specific ISBN restrictions

An ISBN must remain attached to the specific title, format, edition and publisher to which it was assigned.

A paperback, hardback, large-print edition and audiobook may require separate identifiers.

Plan ISBN and Legal Deposit Together

Authors managing ISBN legal deposit UK responsibilities should decide on the publisher and format before uploading the book to either platform.

The publishing plan should identify:

• Publishing name or imprint
• Paperback ISBN
• Hardback ISBN
• Large-print ISBN
• eBook ISBN where used
• Audiobook ISBN where used
• Publication date
• Legal-deposit responsibility
• Metadata owner

Using a free KDP ISBN may be convenient for one Amazon-focused print edition.

It becomes limiting when the author later decides to publish the same edition through IngramSpark. KDP’s free ISBN cannot be used outside KDP. An independently obtained ISBN can be used to publish the same eligible edition through other services, provided the title, author, format and imprint metadata match.

Legal deposit remains the publisher’s responsibility regardless of whether the physical copy was printed through KDP or IngramSpark.

Use KDP When Amazon Is the Main Sales Channel

IngramSpark is not automatically the better choice for every author.

KDP may be more practical when:

• Most readers shop through Amazon.
• The author is launching a first book with limited trade demand.
• Bookshop distribution is not a priority.
• The author wants a simple print setup.
• The Kindle edition is central to the strategy.
• The author plans to use KDP Select.
• The book is primarily sold through online advertising.
• The author needs convenient Amazon proof and author-copy ordering.
• The project is a small private or experimental release.

KDP publishes directly into Amazon’s ecosystem and offers tools connected with Amazon book discovery and sales.

An author should not add IngramSpark simply because it sounds more professional. Each platform creates additional files, metadata, reports and administrative work.

Use KDP for Kindle Publishing

KDP is the direct publishing route for Kindle eBooks.

A Kindle book does not require an ISBN through KDP because Amazon assigns an ASIN. Authors can still provide an independently obtained ISBN where their wider publishing strategy requires one.

Kindle publishing gives authors access to:

• Amazon Kindle Stores
• Kindle pricing controls
• KDP sales reporting
• Amazon promotions
• Kindle Unlimited through KDP Select
• Pre-orders for eligible eBooks
• Amazon advertising

IngramSpark distributes eBooks to a wider range of retail and library channels, including non-Amazon outlets.

The author must decide whether the digital edition should be exclusive to Amazon or distributed widely.

Understand KDP Select Exclusivity

KDP Select is an optional 90-day programme for Kindle eBooks.

An enrolled Kindle eBook is included in Kindle Unlimited and may qualify for Amazon promotional tools. During the enrolment period, the digital edition must remain exclusive to the Kindle Store. Print, audio and other non-digital formats may continue to be distributed elsewhere.

An author cannot enrol an eBook in KDP Select while simultaneously distributing the same digital content through IngramSpark to other eBook retailers.

Possible strategies include:

Amazon-Exclusive eBook

• Kindle edition through KDP
• KDP Select enrolment
• Paperback through KDP
• Wider print distribution through IngramSpark

Wide eBook Distribution

• Kindle edition through KDP without KDP Select
• Other eBook stores through IngramSpark or another distributor
• Print through one or both platforms

The decision should reflect actual reader behaviour.

A genre with strong Kindle Unlimited readership may benefit from exclusivity. A professional or library-focused book may benefit more from wide digital availability.

Can Authors Use KDP and IngramSpark Together?

Yes, a hybrid print strategy is possible when it is configured carefully.

A common arrangement is:

• KDP for direct Amazon paperback sales
• IngramSpark for wholesale and non-Amazon distribution
• The same publisher-owned ISBN for the same paperback edition
• Matching title, author, trim size and imprint
• KDP Expanded Distribution left disabled

IngramSpark’s own guidance states that publishers can use KDP and IngramSpark together when they own the ISBN, but warns against enabling KDP Expanded Distribution because it may create a distribution conflict with the IngramSpark listing.

Authors using this method should verify current platform rules at the time of setup.

Do not use:

• A free KDP ISBN on IngramSpark
• Two ISBNs for an identical edition
• Different imprint names for the same ISBN
• Conflicting trim sizes
• Different author-name spellings
• Separate publication dates without a reason
• KDP Expanded Distribution alongside overlapping Ingram distribution

Consistency is essential for retailer and library records.

Why Use KDP and IngramSpark Together?

A hybrid strategy can combine:

KDP Benefits

• Direct Amazon printing and fulfilment
• Strong Amazon availability
• Amazon-specific sales reporting
• Proof and author-copy access
• Author Central
• Amazon Advertising
• A+ Content

IngramSpark Benefits

• Wider wholesale availability
• Bookshop ordering
• Library-channel visibility
• Publisher-controlled discounts
• Returns settings
• Broader international distribution

A hybrid approach adds complexity.

The author must manage:

• Two dashboards
• Two sets of reports
• File specifications
• Pricing
• Metadata
• Publication updates
• Proof copies
• Tax records
• Returns exposure
• Customer and retailer questions

It is useful only when the wider distribution opportunity justifies the additional administration.

Understand Wholesale Discounts

The retail price is not the amount the publisher receives from a wholesale sale.

A wholesale discount gives the distributor and retailer a share of the retail price.

For example, the publisher may set:

• Retail price
• Wholesale discount
• Returns status
• Printing specifications

The remaining publisher compensation is calculated after the discount and printing costs, subject to the platform’s terms.

IngramSpark allows publishers to choose wholesale pricing and returns settings. The discount can affect how commercially attractive the book appears to retail partners.

A high discount may improve trade appeal but reduce the publisher’s earnings per copy.

A low discount may preserve more compensation but discourage retailers from stocking the book.

The author needs to model both outcomes before publication.

Understand Book Returns

Traditional bookshops often expect the ability to return unsold stock.

When a publisher makes an IngramSpark book returnable, retailers may order with less financial risk. The publishing author accepts the possibility of returned copies and related charges.

IngramSpark explains that the publisher can be charged for returned books according to the wholesale terms and selected return treatment.

A bookshop may order twenty copies for an event and return the unsold portion.

The author should therefore ask:

• Can the publishing budget absorb returns?
• Is the book likely to receive speculative trade orders?
• Is an event expected to produce sales?
• What happens to returned copies?
• Will returned books be destroyed or sent back?
• What fees may apply?
• Does the pricing leave enough margin?

Returnability can support trade acceptance, but it is not a free marketing feature.

Calculate the Retail Price Properly

A book priced only for Amazon may become unprofitable through wholesale distribution.

The author should account for:

• Printing cost
• Wholesale discount
• Returns risk
• VAT where relevant
• Platform fees
• Currency differences
• Retail expectations
• Author compensation
• Delivery
• Production investment

A print-cost calculator should be used before finalising the retail price.

The price must also make sense beside comparable books.

An independently published paperback priced far above recognised titles in the same category may struggle, even when the production cost explains the difference.

Do not set an artificially low price that creates no sustainable margin.

Compare Print Specifications

KDP and IngramSpark offer different combinations of:

• Trim sizes
• Binding
• Paper
• Ink
• Colour options
• Cover finishes
• Page limits

The preferred platform may depend on the physical book.

IngramSpark may be considered for:

• Specialist hardbacks
• Trade formats
• Colour interiors
• Library-focused editions
• Bookshop-oriented paperbacks

KDP may be suitable for:

• Standard paperback fiction
• General nonfiction
• Amazon-focused hardbacks
• Simple black-and-white interiors
• Rapid test editions

Authors should compare the exact specification needed instead of judging one platform’s quality from a different book format.

Order physical proofs from every printer that will produce the edition.

Keep the Edition Identical Across Platforms

When the same ISBN is used through KDP and IngramSpark, the product should represent the same edition.

Match:

• Title
• Subtitle
• Author name
• Imprint
• ISBN
• Trim size
• Binding
• Interior content
• Publication date
• Language
• Edition statement

Small manufacturing differences may occur between printers, but the bibliographic identity should remain the same.

A substantially revised book should be issued as a new edition with a new ISBN.

Do not upload corrected chapters to one platform while leaving an older manuscript active on the other.

Finalise the Manuscript Before Choosing Distribution

A manuscript submission format UK literary agents request is different from a print-ready file.

Agent submissions usually use simple formatting designed for editorial assessment.

Self-publishing platforms require completed production files, which may include:

• Print-ready interior PDF
• Full cover file
• Embedded fonts
• Correct page dimensions
• Bleed
• Spine width
• High-resolution images
• Valid ISBN
• Retail metadata

Do not upload an agent-submission Word document directly and assume the platform will produce a professional book.

The manuscript should complete:

• Developmental editing
• Line editing
• Copyediting
• Proofreading
• Interior design
• Cover design
• Final proof inspection

Distribution decisions cannot compensate for weak production.

Complete Nonfiction Fact-Checking

Professional nonfiction book fact checking should be completed before files are uploaded to either platform.

Check:

• Dates
• Names
• Statistics
• Quotations
• Research
• Historical events
• Medical statements
• Legal information
• Financial guidance
• Professional titles
• Organisations
• Sources

Platform distribution may make a book available globally very quickly.

An error in the manuscript can therefore spread across:

• Amazon
• Bookshops
• Libraries
• International retailers
• Review copies
• eBook stores

Correcting the files later may not remove copies already purchased or supplied.

Keep a source log and arrange specialist review when the subject carries significant factual or legal risk.

Create the Index After Typesetting

Authors learning how to index a book should create the final index only after the print interior has stable pagination.

An index may be useful for:

• History
• Biography
• Business
• Academic trade books
• Professional manuals
• Science
• Local history
• Detailed practical nonfiction

The index must match the final page numbers used in the edition.

When using KDP and IngramSpark for the same ISBN, the interior file and pagination should remain consistent.

Do not create one indexed version for IngramSpark and an unindexed version for KDP under the same ISBN.

A professional index requires editorial judgement, cross-references and useful subentries. An automatically generated list of repeated words is rarely sufficient.

Distribution for Podcast-Based Books

Authors who turn podcast into a book may have an audience spread across several countries and platforms.

The distribution decision should consider:

• Listener location
• Amazon purchasing behaviour
• Independent bookshop demand
• Event sales
• Library interest
• Professional or educational use
• eBook preference
• Audiobook potential

A podcast with a strong Kindle audience may support KDP-focused publishing.

A podcast connected with universities, professional bodies or public libraries may benefit from IngramSpark’s wider trade availability.

The book should still be:

• Rewritten from the transcripts
• Structured for readers
• Fact-checked
• Professionally edited
• Cleared for guest permissions
• Designed as a complete publication

A large listener count does not remove the need for a sustainable publishing setup.

Prepare Advance Reader Copies Before Distribution

A campaign involving advance reader copies UK should normally begin after the manuscript and positioning are stable but before the retail launch.

ARCs can help generate:

• Reviewer interest
• Media consideration
• Bookseller awareness
• Library interest
• Early feedback
• Launch quotations

An ARC may be printed through a short-run printer, proof service or print-on-demand platform.

It should be labelled clearly when:

• The cover is provisional.
• Proofreading corrections remain.
• Retail price may change.
• Final pagination is not confirmed.
• The index is absent.
• Publication information is forthcoming.

Do not distribute an ARC as though it were the completed retail edition.

Early outreach can also help determine whether wider IngramSpark distribution is justified. Strong interest from booksellers, libraries or specialist organisations may support the decision.

Update Goodreads After Publication

Goodreads marketing for authors depends on accurate edition records.

When using more than one print platform, check whether Goodreads lists:

• Correct ISBN
• Correct cover
• Correct author
• Publication date
• Format
• Page count
• Publisher
• Series number

One identical edition should not appear as several unrelated books simply because it is printed through different services.

A hardback, paperback, audiobook and large-print edition may have separate records, but they should be connected as editions of the same work.

Incorrect records can divide:

• Reviews
• Ratings
• Reader shelves
• Cover information
• Publication details

Review the listing after every new edition is released.

Use Amazon A+ Content for the Amazon Listing

Amazon A+ Content for books allows KDP publishers to add images, text and comparison modules to eligible Amazon detail pages. It appears within the “From the Publisher” section and must be created for supported marketplaces.

A+ Content may present:

• Series order
• Main themes
• Author information
• Character introductions
• Interior features
• Nonfiction frameworks
• Related titles

A+ Content remains an Amazon-specific retail feature.

It does not appear automatically on:

• Independent bookshop pages
• Library catalogues
• Ingram listings
• Goodreads
• The author’s website

The author needs separate metadata and promotional assets for non-Amazon channels.

Amazon also restricts certain A+ material, including prices, time-sensitive promotions, customer reviews and direct purchase language.

Prepare an Author Media Kit

An author media kit UK journalists, librarians and bookshops can use should explain where the book is available.

Include:

• Book cover
• Title and subtitle
• Author biography
• Publication date
• ISBN
• Format
• Retail price
• Publisher
• Distributor
• Ordering information
• Book description
• Reviews
• Interview topics
• Contact details

For trade outreach, specify:

• Ingram availability
• Wholesale terms where appropriate
• Returns status
• UK publication details
• Event availability
• Local connection

Do not tell bookshops merely that the book is “available online”.

Provide the information needed to locate and order the correct edition.

When KDP Expanded Distribution May Be Enough

KDP Expanded Distribution may suit an author who wants basic non-Amazon paperback availability without managing another print platform.

It may be considered when:

• Only a paperback is required.
• Trade sales are expected to be limited.
• The author does not need direct control over returns.
• Bookshop stocking is not a central objective.
• Simplicity matters more than wholesale flexibility.
• The author is comfortable with KDP’s eligibility and royalty structure.

KDP states that eligible paperbacks may be made available to distributors serving bookstores, libraries and academic institutions. It also states that enrolment does not guarantee distributor acceptance, listing or orders.

Expanded Distribution should therefore be treated as possible availability, not a complete bookshop-sales strategy.

When IngramSpark May Be Unnecessary

An author may not need IngramSpark when:

• The book is sold almost entirely through Amazon.
• The project is private or highly limited.
• The author has no bookshop or library strategy.
• The audience primarily reads Kindle editions.
• The author does not have the budget to absorb returns.
• Managing two systems would create errors.
• The retail price cannot support trade discounts.
• The book is still being tested.
• Direct event sales are the main route.

A platform should solve a real distribution need.

Wider availability creates little value when no marketing activity will make retailers, libraries or readers look for the title.

Common IngramSpark and KDP Mistakes

Frequent problems include:

• Using a free KDP ISBN on IngramSpark
• Assigning two ISBNs to the same edition
• Enabling overlapping expanded distribution
• Using inconsistent metadata
• Setting an unsustainable wholesale discount
• Enabling returns without understanding the financial risk
• Assuming distribution guarantees bookshop stocking
• Publishing before editing is complete
• Pricing only for Amazon royalties
• Forgetting hardback distribution differences
• Enrolling an eBook in KDP Select while distributing it elsewhere
• Uploading different interiors under the same ISBN
• Ignoring legal deposit
• Failing to order proofs
• Treating Amazon A+ Content as universal retail marketing
• Approaching libraries before supplier availability is active

A distribution plan should be documented before any edition is published.

A Practical Platform Decision Process

A UK author can use the following process:

• Define the intended reader.
• Identify where that reader buys or borrows books.
• Decide whether Amazon is the main sales channel.
• Assess independent bookshop potential.
• Assess library and institutional demand.
• Identify planned print and digital formats.
• Choose the publishing imprint.
• Obtain publisher-controlled ISBNs where needed.
• Calculate printing costs and trade margins.
• Decide whether returns are financially manageable.
• Compare platform specifications.
• Complete editing and fact-checking.
• Prepare final print files.
• Order proofs.
• Decide between Amazon-exclusive and wide eBook distribution.
• Use KDP for direct Amazon publishing where appropriate.
• Use IngramSpark for wider trade distribution where justified.
• Disable conflicting distribution options.
• Keep metadata and files consistent.
• Complete legal deposit.
• Prepare review copies, Goodreads records and media materials.
• Monitor orders, returns and reader demand.

The right choice may be KDP, IngramSpark or both.

The decision should reflect how the book is expected to reach readers, not which platform appears more prestigious.

Frequently Asked Questions

Is IngramSpark better than KDP for UK authors?

Neither platform is better for every book. KDP is often stronger for direct Amazon sales, while IngramSpark may be more suitable for wider bookshop, library and wholesale distribution.

Can a UK author publish the same paperback through KDP and IngramSpark?

Yes, when the author owns the ISBN and keeps the edition and metadata consistent. KDP Expanded Distribution should generally remain disabled to avoid overlapping wholesale distribution.

Can a free KDP ISBN be used on IngramSpark?

No. A free KDP ISBN is restricted to KDP and appears under the “Independently published” imprint. Authors using both platforms should obtain and control their own ISBN.

Does IngramSpark guarantee that bookshops will stock a book?

No. IngramSpark can make a book available through wholesale channels, but individual retailers decide whether to order or stock it.

Should an author make an IngramSpark book returnable?

Returnability may make the title more acceptable to physical retailers, but returned books can create significant charges. Authors should review the current terms and budget for the financial risk before enabling it.

Can a Kindle eBook be published through KDP and IngramSpark?

Yes, provided the eBook is not enrolled in KDP Select. KDP Select requires Kindle digital exclusivity during each 90-day enrolment period.
