How it works
- Add a customer with their name and WhatsApp number.
- For each purchase on credit, type the amount and tap "+ Credit". For each repayment, "− Payment".
- The balance updates by itself, and the list shows the biggest balances first.
- "Send balance on WhatsApp" opens a ready message, for example: "Hello Karim, your balance at Salam Grocery is 350.00 MAD."
Where is my data?
Only in the browser on your phone or computer: nothing is sent to PosSwift or anyone else. So if you change phones or clear the browser, the book is gone. Download a backup now and then and keep the file; you can restore it on another device.
When the book isn't enough
On Pro, PosSwift keeps customer accounts and credit inside the till: a credit sale is recorded as you ring it up, with printable account statements, plus stock and reports. On Android tablets and Windows PCs, even offline.
