Automating Toast POS to R365 GL Mapping Discrepancies

When Toast sales categories drift out of sync with the Restaurant365 chart of accounts, the daily sales journal posts variances that operators spend hours chasing. The blueprint below shows the deterministic mapping jiesen.ai applies before any LLM reasoning runs.

The Blueprint

Worked example — single-day mapping

Toast Daily Sales Summary for one location on a single business day, mapped to R365 GL accounts. Variance > $0.50 escalates for review.

Toast: Food Sales	→ R365 4000 · Food Revenue · $4,812.40
Toast: NA Beverage	→ R365 4010 · NA Bev Revenue · $612.15
Toast: Beer & Wine	→ R365 4020 · Alcohol Revenue · $1,204.00
Toast: Comps	→ R365 6300 · Promo Expense (contra) · ($98.00)
Toast: Voids	→ Suspense 1999 · review if > $25 · $14.50
Toast: CC Tips	→ R365 2310 · Tips Payable · $1,041.20
Toast: Sales Tax Collected	→ R365 2210 · Sales Tax Payable · $537.12

RULE mapping_check
  IF abs(toast.gross_sales - sum(R365.revenue_lines)) > 0.50 THEN
    OPEN ticket(category="mapping_variance", attach=daily_summary, gl_extract)
  END
RULE tips_accrual
  POST 2310 = toast.cc_tips + toast.cash_tips_declared
  WHERE shift.closed = true

Deterministic rules run before LLM commentary is generated.
