Double-entry enforced at the API boundary
VerifyPost 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.
One-week evaluationRunnable
01get keys, post a balanced journal, then an unbalanced one. Confirm the rejection.
02retry a write; check the ledger recorded it once.
03create an invoice, pay it, reverse the payment; read the audit trail end to end.
04run the trial balance after the reversal; it must tie out.
05export everything; review what leaves with you.
The checklist
Eight tests that expose correctness, portability, commercial risk, and production readiness.
Append-only ledger with explicit corrections
VerifyReverse a posted entry, then pull the audit history. The original must survive with the correction linked to it.
Idempotent writes
VerifyRetry the same request. Ask specifically what happens — the answer should be 'the original response, once'.
Full data export, any time
VerifyExport everything mid-trial and inspect what you would actually take with you if you left. Resistance here is a signal.
Public API spec and self-serve sandbox
VerifyIf you cannot post a journal before talking to sales, the developer experience after the contract will not be better.
Clear pricing and commercial scope
VerifyCheck the per-entity shared rates, what counts as an Op, and when a partner or private-deployment quote applies.
Honest compliance posture
VerifyAsk for certification status in writing. 'On the roadmap' stated plainly beats certification theater that collapses under 'who is your auditor?'.
Deployment options that match your constraints
VerifyEmbedded 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 — review shared pricing and what counts as an Op.
The one-week evaluation
You do not need a committee. Five sandbox sessions answer most of the checklist:
- Day 01get keys, post a balanced journal, then an unbalanced one. Confirm the rejection.
- Day 02retry a write; check the ledger recorded it once.
- Day 03create an invoice, pay it, reverse the payment; read the audit trail end to end.
- Day 04run the trial balance after the reversal; it must tie out.
- Day 05export everything; review what leaves with you.
A failed test is useful evidence. Record the response, workaround, and owner before moving on.
