OTO Cross-Module Operations Cheat Sheet

Follow the evidence

Source record → correct party/location → date → quantity/unit → amount/currency → tax/payment method → status → destination record → report.

Purchase to stock

Requisition → approval → PO → receipt/count → GRN → stock post → supplier and finance match. Stop on product, unit, quantity, price, tax, or total difference.

Stock to POS

Product/UoM conversion → POS item/sides/price/tax → order → KOT → bill → payment or room charge → consumption → sales/payment/stock reports.

POS to room

Correct bill → correct in-house guest/room → send once → verify POS status → verify Front Desk POS Bill charge → collect at stay → avoid duplicate payment.

Daily close

POS orders/bills → Front Desk stays/charges/payments → Inventory receipts/stock → Back Office cash/expenses/accounts → exception handover → Supervisor → New Day once → verify next date.

Stop and hand over

Mismatch, duplicate, unclear owner, unexpected balance, or blocked New Day → preserve records → do not submit a false correction → record code, expected vs actual, checks, owner, and next action.
