O6: inventory consumed on jobs posts DR COGS / CR Inventory, but neither recompute
engine reflected it — so reports understated COGS / overstated inventory and a
"Recalculate Balances" wiped the effect. The COGS posting fires only for JobUsage
and Waste transaction types, which are created only at the two COGS-posting sites,
so the consumption is exactly identifiable from InventoryTransaction:
- both posting sites now record consumption at the effective (weighted-average)
unit cost so TotalCost equals the COGS posted (the recompute reads TotalCost)
- LedgerService: new section (dated rows + prior balance) crediting Inventory /
debiting COGS from JobUsage/Waste rows on items with both accounts mapped
- FinancialReportService: Trial Balance + accrual P&L include consumption COGS
This reads existing transactions, so historical data is covered with no backfill.
The Balance Sheet inventory line is intentionally left alone — it does not track
inventory purchases either (periodic), so relieving it for consumption alone would
unbalance it; tracked as O9 (inventory capitalization policy).
O8: the write-off already creates a balanced posted JournalEntry (both engines read
it via their JE-line sections). The real defect was 4 "Status != WrittenOff" filters
in FinancialReportService that excluded pre-write-off payments from AR credits and
bank debits — leaving the paid portion dangling as open AR and understating the bank.
Removed those filters; AR now nets to zero for written-off invoices and the trial
balance balances. No backfill needed.
Adds a LedgerService regression test for inventory consumption. Build clean; 293
unit tests pass.

ApplyGiftCertificate posts DR 2500 Gift Certificate Liability / CR AR, but the AR
recompute only subtracted payments and credit-memo applications — so the redemption's
2500 debit was recomputed while its AR credit was not, leaving the Trial Balance out
of balance by the total gift-certificate amount redeemed and overstating AR on the
Balance Sheet.
Subtract GC redemptions from AR in both recompute engines:
- FinancialReportService: Balance Sheet (gcRedeemedBs) and Trial Balance (gcRedeemedTb)
- LedgerService: AR section (dated rows) and ComputePriorBalanceAsync (prior balance)
AR Aging was already correct (uses BalanceDue, which includes GiftCertificateRedeemed).
Adds a LedgerService regression test. Build clean; 292 unit tests pass.

O1: account 2300 has always been used by the deposit GL code as the Customer
Deposits liability (resolved by number), but it was seeded/named "Payroll
Liabilities" for tenants the AccountingDepositsGL migration's NOT EXISTS guard
skipped — so the liability was mislabeled on the balance sheet. Rename 2300 to
"Customer Deposits" (IsSystem) and move payroll to a new 2400 account:
- both seed paths (SeedDataService.Accounts, SeedData)
- EnsureSystemAccountsAsync self-heal (renames only where still default-named,
preserving user renames; ensures 2400 exists)
- migration RenameDepositsAccountAddPayroll for existing tenants
Account number 2300 is unchanged, so the deposit posting code needs no changes.
O2: LedgerService never recomputed 4950 Sales Discounts, so "Recalculate
Balances" wiped it to JE-only and the Balance Reconciliation report showed false
drift. Add a 4950 section to GetAccountLedgerAsync and ComputePriorBalanceAsync
that reproduces the actual postings (invoice discounts DR + credit-memo issuance
DR, less the unapplied remainder of voided memos CR), matching AccountBalanceService.
Adds a LedgerService regression test for 4950. Documents both fixes plus the
remaining open findings (O3, O4) in docs/ACCOUNTING_AUDIT.md so the audit is no
longer lost. Build clean; 291 unit tests pass; migration applied.

Audit finding 9b: store-credit refunds and credit memos posted nothing to the GL
on issue (only a CreditMemo + Customer.CreditBalance), so outstanding store credit
was invisible on the balance sheet and the contra-revenue was recognized only on
apply. Introduces a 2350 "Customer Credits" liability so the credit is on the books
from issue to apply.
Model (chosen): lifecycle-equivalent to before, plus the liability is tracked.
- Issue (credit memos, goodwill, and store-credit refunds): DR Sales Discounts
(4950) / CR Customer Credits (2350).
- Apply: DR Customer Credits / CR AR (was DR Sales Discounts / CR AR).
- Void unapplied remainder: DR Customer Credits / CR Sales Discounts.
Posting updated in all 8 sites: CreditMemosController Create/Apply/Void and
InvoicesController IssueCreditMemo/IssueRefund(store credit)/ApplyCredit/
VoidCreditMemo/CancelRefund. New 2350 account (seed + self-heal).
Reporting moved in lockstep so the books still balance: the 4950 contra-revenue
shifts from applied -> issued (active memos in full + applied portion of voided),
the 2350 liability = unapplied balance on active memos, AR still credited by
applications. Updated in FinancialReportService (balance sheet retained earnings,
trial balance, P&L) and LedgerService (per-account + prior-balance 2350 section).
Verified the balance-sheet identity for active and voided memos by hand; new
ledger test covers the 2350 lifecycle. Build clean; 284 unit tests pass.
Note: pre-existing quirks left untouched (out of 9b scope) — account 2300 is
seeded as "Payroll Liabilities" but resolved as Customer Deposits in code, and
LedgerService doesn't recompute 4950 so RecalculateBalances understates it; both
predate this change.

Audit finding 9a: a cash refund posted DR AR (control up) while the customer
subledger went down — opposite directions, guaranteeing AR drift. Per the chosen
model, a cash refund now *reverses the sale*: DR Sales Returns (revenue portion)
+ DR Sales Tax Payable (tax portion) / CR Bank, with the customer AR balance left
untouched (the invoice stays paid; the sale is contra'd).
- New 4960 "Sales Returns & Allowances" contra-revenue account (seed + self-heal).
- Tax/revenue split centralized in Core RefundAllocation.Split so the posting and
both reporting recomputes compute it identically (a mismatch would unbalance the
trial balance).
- InvoicesController IssueRefund/CancelRefund: new posting + reversal; no AR/
customer-balance change.
- LedgerService (per-account + prior balance): refunds debit Sales Returns + Sales
Tax, no longer debit AR; bank credit unchanged.
- FinancialReportService: trial balance, balance sheet (retained earnings + tax
liability), and P&L (contra-revenue line) all updated to match. Store-credit
refunds are excluded everywhere (they post via CreditMemo, not the GL — 9b).
Verified: $108 refund (incl. $8 tax) -> bank -100... checks: assets -108 =
liabilities -8 + equity -100. New tests cover the split invariant and the ledger
postings. Build clean; 283 unit tests pass.
