Payment Methods
Every way a customer can pay, mapped to the right account before the first sale.
What it does
Master-data screen for the configured list of payment methods available at checkout - cash, card networks, and any others in use - each one's description and the GL account it settles to.
How it works
Pick a method to edit
Double-click a row to load its description and linked account into the edit fields.
Point it at the right account
Every payment method needs a real linked account before it can be used to settle a sale - checkout validates each method's account link at the moment a sale posts.
Save just that one row
Changes apply to the single edited method, not a resend of the entire list.
The problem it solves
Split-tender checkout only works if every payment method actually lands somewhere in the books - a card payment with no linked account would post a sale with nowhere for that money to go. Validating the link before a sale is allowed to post, rather than after, catches a misconfiguration before it becomes a stuck, half-posted transaction.
