Barcodes and direct selling

I want to ask about whether you will make barcodes and direct selling in your next updates

Barcodes have nothing to do with accounting software.
They are a means of data entry - they replace or supplement a keyboard or mouse.

What do you mean by “Direct selling”?
You can enter sales using a Receipt payment for cash sales and using a Sales Invoice for credit sales

I have a wholesale company and I also have retail branches that need a barcode for easy selling

If you attach a bar code reader to the PC you can use it to read a bar code instead of typing in the data for example a product code

You need to give more detail about the selling process than you have so far to get better reply
