Osiris vs Passare: which one should you pick?
These two are hard to separate on features. They are easy to separate on what each one is willing to put in writing. Osiris publishes a starting figure, its billing terms and a claim about its own ownership. Passare publishes none of those, and publishes far more about what its software does. Below, the pick for each situation, with everything read on the vendors’ own pages.
What each vendor's own page shows
Which one, depending on what you are solving
Take the two you are comparing first, because the answer there is not a tie. Osiris publishes a floor ($79 a month and up, tied to your at-need call volume), then asks you to contact it for a custom quote. Passare publishes nothing: no pricing page, no pricing link, and a 404 at www.passare.com/pricing. Wrenbook is tiered on volume exactly as Osiris is, and the difference is that both ends of the tiering are printed on the pricing page: $149 up to 75 calls a year and one location, $249 up to 300 calls and three, with no setup fee, no contract and migration included. That is the extent of the claim: a published range, not a better product.
Passare’s help center documents case sync into Georgia’s and Pennsylvania’s death registration systems. In Georgia the button sits on the case itself: press GA EDRS Sync, enter your GAVERS username and password, and a green message reports the result, with the GAVERS case ID kept next to the integration afterwards. Read what it asks of you before you count the hours saved: the button stays disabled until the decedent’s first and last name, gender, date of death, date of birth and assigned funeral director are filled in, and three wrong passwords in a row lock you out of the integration. Even so, this is the second entry, and it is gone. Osiris names electronic death records nowhere on its site. Neither does Wrenbook: it produces the Georgia documents from the case, records where a filing stands, and does not push the record into any state registry. On this job Passare is the better tool, and there is no arithmetic that changes it.
Osiris is the only one of the three that publishes what somebody loads for you before you go live, itemized on its own pricing page: "Complete Entry of Your Price Lists (GPL, CPL, OCPL)", "All Government Forms Included (Federal, State, Local)", a dedicated customer success manager, and dedicated time with a QuickBooks and accounting specialist. Passare answers the same worry with a library rather than a hand: "Choose from 1000+ government, state, and local documents or add your own", with case details added to them instantly. That is a wider catalog than Osiris publishes a list for, and it is still you who does the loading. Wrenbook publishes free migration and no setup fee, and its form library is Georgia. That is the one state built today, no roadmap of others is published, and a second state is not a setting somebody switches on during onboarding. If the forms you file are not Georgia’s, this one is not ours.
Passare publishes "30+ integrations" and its help center lists them by category, naming the partners in each: websites with funeralOne, CFS and MKJ, print with Make it! Personal and Director’s Print Suite, answering services with ASD, live streaming with OneRoom and MemoryShare, cemeteries with webCemeteries, plus aftercare, preneed, payments and financial reporting with Federated and PFA. Osiris names four: QuickBooks Desktop and Online, Dropbox, its own e-signatures, and its own ePay for billing families directly. Three of those stay inside the office and the fourth is its own, so none of them is a third-party website, print or streaming vendor. Look at what most of Passare’s list actually touches, though, because that is what decides this one: the website, the obituary, the printed folder, the stream, the family’s payment. Wrenbook has no page a family ever sees. No site, no obituary, no store, no online payment. It is an internal tool for the firm, so there is nothing on that side to plug anything into, and it is not in the running here.
Both of the others publish claims about saving data entry, and both are about the second entry rather than the first. Osiris says it "captures all of your data in one central, affordable system and distributes it instantly to all other integrated components to eliminate redundant efforts". Passare says case details are added to your documents instantly, across a library of more than a thousand of them, which is a far wider set of paperwork than Wrenbook fills. Neither says anything about how the case gets populated in the first place, which is where the two to three hours actually go: the call at 2am, then thirty fields typed from a notepad. That first step is the whole of what Wrenbook automates, and its four Georgia documents come out of it rather than being keyed in after it: the death certificate worksheet (Form 3903, items 1–26b), the SSA-721, the disposition permit (Form 3934, O.C.G.A. § 31-10-20) and the cremation authorization (Ga. Comp. R. & Regs. R. 250-6-.09). Four documents in one state, against a library of more than a thousand. Outside Georgia, the re-entry stays.
What each one does, and where it stops
Osiris
Puts three things in writing that Passare keeps for the demo. What it costs to start: plan prices begin at $79 a month, tiered on at-need call volume. What you are signing: month by month, no contracts or long-term commitments, cancel at any time. And a claim about who owns it: "independently owned and operated", with "a promise that we won’t sell our products through you". Onboarding is itemized too: complete entry of your GPL, CPL and OCPL, all government forms (federal, state and local), a dedicated success manager, and dedicated time with a QuickBooks integration and accounting specialist. Its trial is published on a separate page and takes a form rather than a demo: "Try Osiris, commitment-free, for 30 days", billed only if you continue afterwards. On integrations it names QuickBooks Desktop and Online with a two-way link, Dropbox, its own ePay billing and its own e-signatures.
The $79 is a floor. What you actually pay is tiered on your call volume and arrives as a custom quote, and the enterprise tier is a "contact us directly". The independence claim needs reading next to the footer of the same page, which calls Osiris "an exclusive product of our parent company, Funeral Director’s Resource". Two software directories list it at $100 a month, both calling that a flat rate, on a plan the vendor prices by volume. And electronic death records are not named anywhere on its site: not in its features, not in its integrations, not on its pricing page.
Passare
Documents more of what it does than the other two here. Its help center covers case sync into the Georgia and Pennsylvania death registration systems, which is the part of the chain the other two leave to you. It publishes "30+ integrations" and its help center lists them by category, naming the partners in each: websites, print, answering services, aftercare, preneed, payments, live streaming, cemeteries. On documents it publishes the widest library of the three, "Choose from 1000+ government, state, and local documents or add your own", with case details added to them instantly, and eSignature requests sent without leaving the case. There are iOS and Android apps. Its direct QuickBooks Online integration posts journal entries without an export file. The company says 2,600+ funeral homes use it, and reports a 96% customer service approval rating.
Nothing about cost is published: no pricing page, no pricing entry in the navigation, and www.passare.com/pricing returns a 404. Every invitation to buy is a demo or a meeting, and no trial is offered anywhere on the site. Its QuickBooks Online connection is not something you switch on yourself either: the help center asks you to fill in a form so it can set it up for you. The same is true of the death registration link, which support enables before you can use it. And the page that sells its financial tooling names no accounting vendor at all, which makes the catalog harder to check than its length suggests.
Wrenbook ours
Turns the recorded first call into the case file: transcribed, drafted, and each field linked back to the sentence it came from, with nothing leaving the case without a sign-off. The case then fills the Georgia death certificate worksheet, the disposition permit, the SSA-721 and the cremation authorization instead of being retyped into them. Holds a versioned, dated General Price List, and builds the itemized Statement of Goods and Services from the arrangement selections, time-stamped. Both figures are on the pricing page, split on annual case volume and on locations, with no setup fee, no contract and migration included. The same page publishes the trial as thirty days with no card, and says that cancelling exports your cases, documents, contacts and price lists in one archive.
The newest and narrowest product of the three. Georgia is the only state built today, and no roadmap of other states is published. Wrenbook records where a filing stands; it does not push the case into a state registry. Its form library is that one state, against the thousand documents Passare publishes and the federal, state and local forms Osiris says it loads for you. It names no integration partner and has no mobile apps. Nothing about what its own onboarding loads for you is published beyond free migration. On ownership it publishes the company that operates the service and stops there, which the reading above sets out.
Where this information comes from
- 01 Prices and product claims were read on each vendor’s own pages, in a browser, on August 28, 2026.
- 02 Where a vendor publishes no price, this page records the absence rather than an estimate. Software directories were not used as a price source: two of them list Osiris at $100 a month, where the vendor’s own page says $79 and up, tiered on call volume.
- 03 These pages were read from France. Osiris displays its figure in US dollars as running text, on a page that offers no currency choice.
- 04 What each vendor says its product does is its own claim, attributed here rather than confirmed. This page has no first-hand use of the other two products.
- 05 The situations were rewritten after this page was first published, and each one was re-read at its source rather than carried over: osirissoftware.com/pricing and its start-free-trial page, osirissoftware.com for its integrations and its claim about central data entry, support.passare.com for the Georgia death registration article and the integration categories, passare.com/integrations and passare.com/docs for the counts it publishes, and wrenbook.com/pricing for both figures and the trial.
- 06 One situation was dropped rather than rewritten. It asked which vendor lets you try the software before committing, and the reading separated two of the three rather than one: Osiris publishes thirty days by form, Wrenbook publishes thirty days with no card, Passare publishes no trial. What each one offers is in its row above instead.
- 07 Prices and features in this market change without notice. The date above is when this page was read, not when it was published.
