Print Serial / IMEI Numbers as Barcode Stickers and use them in Sales Invoice

Instead of printing Barcode numbers, Munim also allows you to print Serial/IMEI numbers.

Those stickers can be put on the products and used when making sales invoices by scanning.
The user has the option to select either barcode or Serial/IMEI numbers for printing by selecting the “Print Serial/IMEI No.” option, provided that both number types have been added.
Now, while creating a Sales Invoice, you don’t need to manually search for items.

This ensures faster billing, error-free selection, and accurate stock deduction.

Serial Number Reports & Tracking

Munim provides reports to track items serial number-wise.

You can view in this report:
- Which Invoice has which serial/IMEI number (sales tracking).

- Stock Status serial number-wise with the Status column.
These reports help in after-sales support, warranty claims, and returns.

Invoice Print with Serial/IMEI Numbers

When you generate and print a Sales Invoice that contains Serial/IMEI-managed items, the Serial/IMEI numbers will automatically be displayed below the item details.
This ensures that both you and your customer have a clear record of which serial/IMEI numbers were sold.
