Excel vs shop POS
A spreadsheet is free. A phone shop pays when IMEI and the shift do not match in the morning.
What Excel still wins
One owner, one file, no staff. Charts you already know. NextPay does not replace your accountant’s workbook.
Where the shop breaks
Two sellers edit the same file. IMEI is a row someone forgets. The shift never closes. Payroll is a guess. The second phone overwrites the first.
What NextPay actually does
Browser POS: cash, terminal, inventory, IMEI, repairs, open/close shift. Server is the book, with backups and up to five devices. Not a Play app. Auto-pay is not live — trial is.
