Closing Retail shop - stop fresh invoice

I did a request for goods. set the timer for 48hrs, waited close to that (maybe, i forget) ran out of goods… so was like, well ill just close and sell.

 just before the time ran out, the Producer shows up and accepts the invoice.

(Soon as closed it should have prevented that being accepted)
goods sent (to a closed biz?) i paid for items as the items were sent. not the producers fault.

This seems like a bad timing issue.

Exactly that.
