“IMEI numbers required” message

For products that track IMEI or serial numbers, every unit you sell needs its number. If any are missing, the invoice shows the IMEI numbers required for mobile products section with the message “Please select all required IMEI numbers before generating the bill” and won’t save.

Fix it

1. Scroll to the IMEI section of the invoice.
2. For each product line, select one IMEI / serial number for every unit in the quantity. Selling 2 phones needs 2 numbers.
3. Save the invoice again.

The number isn’t in the list

• Only numbers that are in stock are listed. Check that the purchase invoice for that unit was recorded with its IMEI. Track IMEI and serial numbers
• A number already sold on another invoice is not offered again.
• Check the quantity: if you typed 3 but are selling 2, correct the quantity.
