Tax rules change often, and keeping clean records by hand is hard when you bill hundreds of customers a day. A good POS system won't file your returns for you, but it will give you the accurate sales, purchase and tax records that VAT compliance depends on. This guide covers the basics every Sri Lankan shop owner should know.
This article is general information, not tax advice. Rules can change — always confirm with the Inland Revenue Department or your accountant.
VAT in Sri Lanka at a glance
- Standard rate: 18% from 1 January 2024.
- Registration threshold: you must register if your taxable supplies exceed Rs. 15 million in a quarter or Rs. 60 million in a 12-month period. A proposed reduction of this threshold was abandoned in 2026, so these limits remain in place.
- When to apply: within 15 days of becoming liable for registration.
- Voluntary registration is possible below the threshold, and importers and exporters of goods for commercial purposes must register regardless of turnover.
Why your POS matters for VAT
VAT is calculated from your sales and purchases. If those numbers live in notebooks, separate spreadsheets and a basic billing app, month-end becomes guesswork. A POS that records every sale, return, GRN and supplier invoice gives you one reliable source for your accountant.
What to look for in a VAT-ready POS
- Tax invoices. Registered businesses must issue proper tax invoices showing the required details, such as your name, address and VAT registration number, the date, the description, quantity and value of goods, and the VAT charged. Your POS should print these consistently.
- Correct handling of returns and voids. Every cancelled or returned bill should be logged, with the user and time, so sales and tax figures reconcile. Visiro includes void invoice reports and supervisor authorisation for exactly this reason.
- Purchase records. GRNs and supplier invoices recorded in the system support your input tax claims.
- Reports by period. Daily, monthly and quarterly sales reports that your accountant can use for returns.
- Audit trail. Logs of stock edits and price changes, with user names and timestamps.
- Backups and record keeping. Records must be kept for years. Automatic backups protect them from hardware failure.
VAT, SVAT and WHT for growing businesses
As a business grows, finance work goes beyond the counter: SVAT for suppliers to exporters, withholding tax, and a full general ledger. That is where an ERP helps. Visiro Cloud ERP adds VAT, SVAT and WHT workflows, banking and accounts payable on top of your POS data — see ERP system for Sri Lanka and POS vs ERP.
Good habits that make VAT easier
- Record every purchase as a GRN on the day stock arrives, with the supplier's invoice number.
- Never delete bills. Use returns and voids so there is a trail.
- Give each cashier their own login (PIN or QR) so every transaction is traceable.
- Close each day with a cash and card reconciliation report.
- Share monthly reports with your accountant rather than raw notebooks.
Pricing, VAT and your POS
Decide early whether your shelf prices include VAT and set the POS up the same way, so cashiers never calculate tax by hand. When the rate or your registration status changes, update prices and tax settings in the POS once rather than on every bill. Keep a note of the date of each change so your accountant can match reports to the right period.
Approaching the threshold? Plan ahead
Because registration depends on turnover, growing businesses should watch sales against the Rs. 15 million quarterly and Rs. 60 million annual limits. A POS makes this simple: monthly and quarterly sales reports show exactly where you stand, so you can talk to your accountant and prepare your invoices and records before you become liable, not after.
Which Visiro POS fits?
Single shops that want a one-time purchase usually choose offline POS, such as our supermarket or retail versions. Multi-branch businesses that want central reporting choose cloud POS. Both keep the sales, purchase and audit records described above. Pharmacies, hardware stores and restaurants have industry versions too — see the POS system guide.
