Harmony Publishing vs DiggyPOD

DiggyPOD is a US book printer for self-publishing authors, with ISBN and distribution services alongside its printing.

Short version. DiggyPOD prints books, and also offers ISBN, barcode and distribution services; we produce books and print them. If you already have professionally finished, print-ready files, a printer is a direct and cost-effective route. If your manuscript still needs editing, cover design or interior layout, that work has to happen before any printer can produce the book, and that is the part we do.

Which should you choose?

Choose Harmony if…

  • You want the whole run priced up front: our calculator gives the delivered price of 100 to 10,000 copies (for the common black-and-white paperbacks) before you commit, with the freight as its own line when the shipment is heavy.
  • You want one team across editing, design, print and distribution, an ISBN registered in your name or your own imprint, and no share of your royalties.
  • You want the interior formatted and the cover designed as part of one package: with DiggyPOD you format the interior and make the print-ready PDF yourself, and cover design is a separate service. (diggypod.com/how-to-publish-a-book, checked 15 October 2026)

Choose DiggyPOD if…

  • You have a finished interior and cover and want a printer that checks your PDF files before you order: DiggyPOD says its free check will 'get accurate print pricing in just a few clicks'. (diggypod.com, checked 15 October 2026)
  • You want spiral binding as well as paperback and hardcover: DiggyPOD lists all three. Our calculator prices paperback and hardcover. (diggypod.com, checked 15 October 2026)
  • You want ISBN registration, a barcode and distribution handled by the printer you order from: DiggyPOD offers an ISBN service, barcode creation and distribution to Amazon and other retailers. (diggypod.com/self-publishing/isbn-number, checked 15 October 2026; diggypod.com/distribution, checked 15 October 2026)

Switching probably isn't worth it if…

  • You are reprinting a finished book: DiggyPOD says that once you print with it 'you can easily reorder or make changes for future prints', and nothing about the service is failing you. (diggypod.com, checked 15 October 2026)
  • You bought the ISBN yourself and only need printing: the ISBN is yours either way, so moving gains nothing but a different printer.

Our figure is the live output of our calculator at the moment this page was shown. Where the quantity is small, delivery is included in the price; for a heavy shipment the freight is its own line at the carrier's cost, with no markup. Prices exclude sales tax. A competitor price appears here only with a source and the date we checked it; until we have captured one, the cell says so. We never estimate a competitor's price.

Switching to Harmony from DiggyPOD

If you decide to move a book you have already published, this is what carries over, what does not, and an order of steps that keeps the book available the whole time.

What moves with you

  • Your files. You supply the print-ready PDF to DiggyPOD, so keep your own copies of the interior and the cover. (diggypod.com/how-to-publish-a-book, checked 15 October 2026)
  • An ISBN you bought yourself. It is yours to use with any printer.

What does not

  • An ISBN registered through DiggyPOD's service, if it is registered to DiggyPOD. The pages we read say DiggyPOD registers and reserves the ISBN, but not whose name it is registered in: ask before you plan the move. (diggypod.com/self-publishing/isbn-number, checked 15 October 2026)
  • Retailer listings and reviews tied to the old ISBN. A new ISBN starts as a new listing, and whether reviews can be carried over is the retailer's decision.

The order of steps, so the book is never unavailable

  1. Keep your interior and cover files, and leave the existing listing live while you move. (diggypod.com/how-to-publish-a-book, checked 15 October 2026)
  2. Decide the ISBN: keep one you own, or take a new one with us.
  3. Order a single proof copy from us (the calculator prices one copy) and approve it.
  4. Publish the new edition with us and check it is live on Amazon and the other stores you sell through.
  5. Only then ask DiggyPOD to end its distribution of the old edition. Its distribution page does not say how to remove a title or how long that takes, so ask first. (diggypod.com/distribution, checked 15 October 2026)

What to check first

  • Whose name is the ISBN registered in? If you bought it, you can keep it. If it came from a service, ask. (diggypod.com/self-publishing/isbn-number, checked 15 October 2026)
  • Do you hold the print-ready PDFs for the interior and the cover? (diggypod.com/how-to-publish-a-book, checked 15 October 2026)
  • Is the book in DiggyPOD's distribution? Its public pages do not say how to end it. (diggypod.com/distribution, checked 15 October 2026)
  • Does the book meet the trim and page limits of the new print run? Check them in the calculator.

To price a reprint or a proof copy before you move anything, use the calculator.

Three questions to ask any provider

Including us. The answers decide more about value than the headline price:

  • Ask who the publisher of record will be. If it is not you or your imprint, understand why before you sign.
  • Ask what royalty share they take. Any percentage of your sales is a cost that compounds over the life of the book.
  • Ask whether you receive your editable source files. If you cannot take your interior and cover elsewhere later, you are locked in.

On all three, our answer is: you are the publisher of record, we take no royalties, and you receive your print-ready and editable files.

How this comparison was made

  • Prepared by the Harmony Publishing editorial team.
  • DiggyPOD's public product, help and terms pages were read on the dates in the sources list; nothing was purchased, and no account was opened.
  • Our figures are the live output of our own calculator, for the scenario stated above.
  • A competitor price appears only with a source and the date it was checked; until we have captured one, the cell says so. We never estimate a competitor's price.
  • Facts checked: 15 October 2026. Each source below carries the date it was checked, which can be earlier.

Frequently asked questions

Is DiggyPOD cheaper than Harmony Publishing?

A print-only price looks lower because less is included: you format the interior, make the print-ready PDF and supply or buy the cover. The comparison only holds if you add the cost of the work you would otherwise arrange yourself. If you already have professionally finished files, a print-only service can be the cheaper route for the printing alone. (diggypod.com/how-to-publish-a-book, checked 15 October 2026)

Does DiggyPOD provide an ISBN and distribution?

Yes, according to its own pages: it offers an ISBN service and barcode creation, and says a book can be distributed on Amazon and other major online retailers. An ISBN is required for wide distribution. (diggypod.com/self-publishing/isbn-number, checked 15 October 2026; diggypod.com/distribution, checked 15 October 2026)

Do I need print-ready files for DiggyPOD?

Yes. You format the interior to the book size you chose and make a print-ready PDF of the interior and cover; DiggyPOD offers a free check of your files before you order. Producing those files is the part we do. (diggypod.com/how-to-publish-a-book, checked 15 October 2026; diggypod.com, checked 15 October 2026)

Can I use both?

Yes. An ISBN is non-exclusive, so a book produced with us can be printed by DiggyPOD, or produced and printed with us and listed elsewhere. There is no conflict.

Can I move a book from DiggyPOD to Harmony?

Yes. Keep your interior and cover files, check whose name the ISBN is registered in, order a proof, publish with us, and only then end the old listing. DiggyPOD's distribution page does not say how to remove a title, so ask it first. (diggypod.com/distribution, checked 15 October 2026)
