How to Enable TDS in Sales Invoice

How to Enable 10% (Proff. Tax) TDS in GST Sales Invoice

see tax withholding document

Home > Accounting > Taxes > Tax Withholding Category

Seems to be solved here:

Hi, documentation seems indicate that Withholding is both for Suppliers and Customers. But when applying it to a Customer, the invoice is adding up the tax instead of deducting from the amount the Customer will pay because he is withholding the money from me.

Here, the sales tax is 16% and it is added correctly. But the ‘retenido’ is something the customer is withholding from the seller (1.25).

I might not be understanding something here. If anyone could point the error it would be much appreciated.
