9. Need Bangla Text Support on print.

Here is sample of how print Will look.

10. We want a POS app for M/S ALI STORE with Bangla language support.

Most of the features we need are already available in the Karbar POS app. If you can create the same type of POS but with some improvements in the invoice printing style, that will be perfect.

👉 Main improvements needed:

Remove unnecessary lines and spaces to make invoice shorter.

Option to enable/disable unit rate column.

Option to enable/disable total amount in words.

Allow editing product price & quantity during invoice creation (e.g. half carton at custom price).

Data export option (CSV/Excel).

Google Drive backup option (reduce server load).

Other than these printing & flexibility updates, Karbar is already a very good reference.
