Tax invoices
What UDS POS does about VAT, why ordinary bills do not show it, and how to issue a tax invoice to a business customer who claims the VAT back.
If your shop is not VAT-registered
Leave Rate % at 0 under Settings → Shop & VAT. Nothing is charged, nothing is printed about VAT, and you can skip the rest of this page.
If your shop is VAT-registered
Under Settings → Shop & VAT:
- Enter your VAT Registration number and the Rate %.
- Shelf prices already include VAT: leave this ticked if your prices are what the customer pays — the usual way in Sri Lankan shops. VAT is worked out from inside the price and recorded against every sale for your own records. The screen shows a worked example as you type.
- Press Save.
Tax invoices for business customers
A VAT-registered business — a company, a garage, a hotel — may need a tax invoice to claim the VAT back. It names both businesses, shows both VAT numbers, and shows the VAT on every line.
To issue them:
- Tick Issue tax invoices under Settings → Shop & VAT (it needs your registration number). Most shops leave it off.
- Add the customer's VAT registration number to their record under Customers, so it prints on their tax invoices — they need it to claim the VAT.
- Open the invoice for that customer and press Issue & print tax invoice.
The first print is the original. To print it again later, open the invoice and press Print tax invoice copy — every later print is marked as a copy.
Which bills can be tax invoices
Only a bill that names a customer. A walk-in sale with no customer on it stays an ordinary bill.
