Summary

Adds docs/architecture/quickbooks-accounting-sync.md — the accounting design for syncing DDB Stripe payments into QuickBooks Online without double-counting money the existing Stripe/bank path already represents. No bookkeeping writes are implemented; this document is the gate for that work.

The design was informed by read-only inspection of production state (Firestore via admin reads, Vercel runtime logs) — no production writes or mutations of any kind.

Changes

  • New docs/architecture/quickbooks-accounting-sync.md covering: current state (verified prod evidence: CW/Curaçao company, unset mapping, captured payment facts, missing fee/payout data), the existing Stripe→QBO unknown with a blocking pre-flight inspection checklist, double-counting risk matrix, options A–D, the recommended model (gross Sales Receipts → Stripe clearing account; app posts the revenue leg only — never deposits, fees, invoices, or journals), RefundReceipt refund model, clearing reconciliation, conservative no-tax-posted posture for the non-US company, mapping verdicts, per-type idempotency, failure/retry semantics, rollout plan, and a manual verification checklist.
  • docs/operations/quickbooks.md — the "deliberately not built" section now links to the design doc.

Follow-up implementation issues filed: #178 (pre-flight inspection gate — blocking), #179 (Sales Receipt posting), #180 (refund sync), #181 (clearing/payout reconciliation + fees), #182 (mapping UI), #183 (retry/sweeper/visibility), #184 (non-US tax decision).

Verification

  • npx tsc --noEmit
  • npm run lint
  • npm run check:md-links
  • npm run check:react-versions

Docs-only change — unit/rules/build/Playwright unaffected (no code touched).

Risk / deployment notes

  • No secrets, credentials, or private data were committed. Production realm id and entity ids do not appear; company name/country are already public business facts.
  • No behavior changes; no QBO writes exist. The doc explicitly blocks posting work on the pre-flight inspection of what the existing Stripe→QBO path creates.

Summary by Sourcery

Document the gated design for syncing Stripe payment revenue to QuickBooks Online without double-counting existing accounting activity.

Enhancements:

  • Add a comprehensive design for a future Stripe-to-QuickBooks accounting sync that prevents duplicate revenue, cash, and fee postings.
  • Define the proposed revenue, refund, clearing-account, tax, mapping, idempotency, retry, and rollout policies for accountant review.
  • Document the blocking pre-flight inspection required before enabling any QuickBooks writes.

Documentation:

  • Link the QuickBooks operations guide to the new accounting sync design as the required reference before implementing postings.

Summary by CodeRabbit

  • Documentation
    • Added a proposed approach for reconciling settled Stripe payments and refunds in QuickBooks Online, with guidance on account mappings, tax and currency checks, retries, rollout, and manual verification.
    • The proposal is pending accountant review and recommends checking for existing revenue postings before any implementation to avoid double-counting.
    • Updated the QuickBooks operations guide to highlight this pre-flight review.
    • QuickBooks write integration is not implemented.

Designs the accounting model for posting Stripe payments into the
production QBO company without double-counting money the existing
Stripe/bank path already represents.

- Recommends gross Sales Receipts into a Stripe clearing account
  (revenue leg only — never deposits, fees, invoices, or journals),
  contingent on a pre-flight inspection of what the existing
  Stripe→QBO path already creates.
- Records production evidence: CW (Curaçao) company — non-US tax;
  mapping confirmed unset; no fees/payout linkage captured today;
  Dashboard refunds invisible to the app.
- Documents RefundReceipt refund model, clearing reconciliation,
  conservative no-tax-posted launch posture, per-type idempotency,
  retry/failure semantics, and a manual verification checklist.

Implementation issues filed as #178–#184. No QBO writes are built.

Reviewer's Guide

This docs-only PR establishes the accounting-sync design and review gate for future QuickBooks writes: inspect the existing Stripe/bank integration first, then—if no revenue leg already exists—post gross payment Sales Receipts to a Stripe clearing account while leaving deposits and fees to the existing path.

Systems and components

  • observed — docs (service) was modified; 2 changed files map to changed impact.

Before / after behavior

  • observed — Modified behavior in docs/operations/quickbooks.md: Added a reference to the accounting sync design and instructed readers to review its double-counting risks and required pre-flight inspection before posting.
  • observed — Modified behavior in docs/architecture/quickbooks-accounting-sync.md: Adds the proposal’s status and production context, documents the payment facts available to sync, and identifies missing fee, payout-linkage, and out-of-app refund data.
  • observed — Modified behavior in docs/architecture/quickbooks-accounting-sync.md: Adds the unresolved inspection gate for existing Stripe/QBO activity and identifies duplicate revenue, cash, and fee risks. The proposed posting model is conditional on inspection confirming that existing activity does not already post revenue.
  • observed — Modified behavior in docs/architecture/quickbooks-accounting-sync.md: Compares Sales Receipt, Invoice-plus-Payment, revenue-only posting, and no-posting options. The document rejects the invoice workflow and reserves reconciliation-only operation for cases where inspection confirms revenue is already recorded.

- Around line 299-302: Update the Launch posture section to specify the required
GlobalTaxCalculation mode for the company’s approved no-tax treatment, using
NotApplicable only if it is valid for this company. Keep the existing TaxCodeRef
guidance and clarify that the Sales Receipt request must include this
transaction field.
- Line 232: Update the paid payment mapping for SalesReceipt to specify that QBO
TxnDate uses the payment’s paidAt settlement date, not the worker’s processing
date.
- Line 174: Update the amount mapping for Sales Receipts and refunds so the
integer USD cents in amountMinor are converted to decimal QBO currency units
before posting; preserve the gross-amount treatment and apply the conversion to
both transaction types.

- Convert amountMinor (integer cents) to QBO decimal units at the
  boundary, for Sales Receipts and RefundReceipts.
- Post TxnDate from the payment's paidAt (refund's refundedAt), not
  the worker date — retries/backfills land in the right period.
- Non-US companies require GlobalTaxCalculation on sales transactions;
  the intended NotApplicable value is confirmed by the pre-flight
  tax check.

docs/architecture/quickbooks-accounting-sync.md:368-373
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Require missing-record recovery before enabling writes.

When the planned producer commits a payment as paid and its post-commit enqueueAccountingTransaction() call fails without creating a sync record, that payment remains outside qboSyncRecords. Section 13 proposes a sweeper but leaves its trigger to the implementation issue. Rollout step 5 and the blocking pre-flight checklist do not require recovery to be implemented and tested. The post-enable QBO-outage check covers a sync record that already exists. Require tested recovery for paid payments with no sync record before enabling writes; otherwise, those payments can remain unsynced until a later sweep or manual recovery.

Suggested fix
-5. Enable writes for **new** payments only; verify the first payout
-   reconciliation with the accountant.
+5. Enable writes for **new** payments only after recovery for paid
+   payments without sync records is implemented and tested; verify the
+   first payout reconciliation with the accountant.
