The tax category of our products has been configured to 12% VAT. The problem is we just found out that our business is NON-VAT so we need to change the TAX category of our products to NON-VAT which has 0% tax. And that must also reflect to the previous tickets that are stored in our database.
-Change the tax categories of products to Non-VAT(0%)
-Previous price of products w/ 12% VAT should still be the same. (ie. (Sell price)100+(12% VAT)12=Total sell price: 112 -> (Sell price)112)
-All previous receipt should also be updated. As if we start with Non-Vat(0%) from day 1.
-Before we accept your offer, we must be sure that you can really handle and understand this job. We will require you to give us a demonstration via Teamviewer. We will enter a few products with 12% VAT in the system and make a sale and closed cash. Then you will show us that you can convert it to Non-vat without affecting the price.
