01
Double-entry enforced at the API boundary
How to verify: Post an unbalanced journal in the sandbox. It must be rejected — not warned about, not silently fixed.
How to evaluate an embedded accounting vendor
Use this checklist against every vendor on your shortlist — including us. It is the standard you would hold your own build to, turned into questions a one-week evaluation can answer.
02
Append-only ledger with explicit corrections
How to verify: Reverse a posted entry, then pull the audit history. The original must survive with the correction linked to it.
03
Idempotent writes
How to verify: Retry the same request. Ask specifically what happens — the answer should be 'the original response, once'.
04
Full data export, any time
How to verify: Export everything mid-trial and inspect what you would actually take with you if you left. Resistance here is a signal.
05
Public API spec and self-serve sandbox
How to verify: If you cannot post a journal before talking to sales, the developer experience after the contract will not be better.
06
Pricing you can model from the website
How to verify: You should be able to estimate your monthly cost before the first call — and the metering unit should be defined in writing.
07
Honest compliance posture
How to verify: Ask for certification status in writing. 'On the roadmap' stated plainly beats certification theater that collapses under 'who is your auditor?'.
08
Deployment options that match your constraints
How to verify: Embedded UI, headless API, white-label, or private deployment — confirm the one you need is real, not roadmap.
Most vendors in this category publish no pricing and gate evaluation behind a sales call. That is not disqualifying by itself — but every unchecked box above is risk you carry into production. Ours is published — model your cost on the pricing page before the first call.
You do not need a committee. Five sandbox sessions answer most of the checklist:
- 1Day 1 — get keys, post a balanced journal, then an unbalanced one. Confirm the rejection.
- 2Day 2 — retry a write; check the ledger recorded it once.
- 3Day 3 — create an invoice, pay it, reverse the payment; read the audit trail end to end.
- 4Day 4 — run the trial balance after the reversal; it must tie out.
- 5Day 5 — export everything; review what leaves with you.
Scored against our own checklist — including what we have not earned yet.
