Payment Status

Definition

The stored fact recording whether a cost has been settled: PAID or UNPAID. Written at the moment of the business event, never derived at query time.

Worked Example

Pay Now flow:
   Cost item created -> expense recorded
   Withdrawal created -> bank balance reduced
   payment_status = PAID    (all in one atomic transaction)

Pay Later flow:
   Cost item created -> expense recorded
   payment_status = UNPAID
   liability_type  = AP or ACCRUED

Interpretation & Pitfalls

A stored status is evidence ("set by user X at time T"); a computed status is an argument that changes whenever the code does. Financial systems store facts. See: stored-vs-computed.

In TupicFinance

payment_status is stored explicitly and updated transactionally together with the matching bank movement.
