A pitch is a temporary but real location
Goods leave home or a stockroom, spend the day at the stall and may return. If they continue to appear at the source, somebody can promise an item that is physically elsewhere. A transfer keeps the business total unchanged whilst showing honest local availability.
Open and close with a repeatable routine
Before trading, check packed quantities, transfer them to the market location, review prices and confirm that the phone has synchronised. During the day, keep sales and money received distinct, especially where a regular customer pays later.
At closing, compare the remaining goods with the app. Damage or loss should be explained rather than invented as a sale. Transfer back only what physically returned.
Plan for crowded networks
Markets, fairs and busy venues can have weak or congested service. Offline-first supported flows allow the record to remain on the handset, but the team must understand that pending is not yet server-confirmed. Keep the device until delivery is complete.
Prepare before the first customer
Set up products, units, barcodes and prices in advance. During a queue, record the essential event with as little friction as possible. Leaving everything for memory at the end loses small sales, part-payments and expenses.
