Quick answer

To switch restaurant POS safely: export everything first (menu, customers, sales and GST invoices), set up and test the new system, train staff by role, run both systems in parallel for a few quiet shifts, then go live on a quiet day at the start of a month with a new invoice series. Keep your old records for 72 months, as GST law requires.

Most POS switches go wrong for one of three reasons: data wasn't exported before the old contract ended, staff weren't trained, or the go-live landed on a Saturday night. This plan avoids all three. For choosing the new system, see our restaurant POS comparison; for the basics, our restaurant POS system guide.

Signs it's time to switch

What to export from your old POS

DataWhy it mattersTip
Menu, prices, categories and taxesRebuilding the menu is the biggest setup jobExport to a spreadsheet; check modifiers and combos
Recipes and ingredientsNeeded for stock deduction and food costExport if available; re-check quantities and yields
Customers and loyalty balancesRegulars, their preferences and pointsExport with consent records; honour points in the new system
Sales history and reportsGST filing, trends and comparisonsExport daily and monthly sales, taxes and item reports
GST invoicesLegal records you must keepExport or download all invoices for every financial year
Suppliers and purchase pricesOrdering and price historyExport the supplier list and recent purchase prices
Open itemsAdvances, gift cards, credit customers, open tablesSettle or list them so nothing is lost
Users and permissionsWho can void, discount and see reportsList staff and their roles

Export before you give notice. Some vendors limit access once a contract ends. Save every export in two places, such as a laptop and cloud storage.

The two-week switching timeline

WhenWhat to do
2 weeks beforeChoose the new POS and go-live date. Check your notice period with the old vendor. Export menu, customers and recent sales.
10 days beforeSet up the menu, taxes, printers and stations in the new POS. Add recipes for your top dishes.
1 week beforeCreate staff logins and permissions. Train each role in a short session. Print test bills and KOTs.
3–4 days beforeRun the new POS in parallel during quiet shifts. Compare totals with the old system.
Day beforeExport final data from the old POS. Count high-value stock for opening balances.
Go-live dayStart on a quiet day at the beginning of a month if possible. Keep the old system available read-only.
First weekCheck day-end reports daily. Fix menu, tax or printer issues fast. Collect staff feedback.

GST, invoice numbers and old records

Confirm the details with your accountant, especially if you switch mid-month.

Running both systems in parallel

For a few quiet shifts before go-live, bill every order in the new POS as well as the old one, or re-enter the day's bills after service. Compare totals, taxes and payment methods. Differences reveal menu, price or tax mistakes before guests see them. Don't run in parallel for weeks; two or three shifts is enough and avoids double work.

Frequently asked questions

How long does it take to switch restaurant POS?

Plan about two weeks: a few days to export data and set up the new system, a few days of training and a short parallel run. The actual switch can happen in a single day; billing setup on a cloud POS often takes just a few hours.

Will I lose my sales history when I change POS?

Not if you export it first. Download your sales reports, GST invoices and customer list before you cancel the old system. Your old vendor may not keep your data after the contract ends.

How long do I need to keep my old POS records?

Under Section 36 of the CGST Act, registered businesses must keep accounts and records for 72 months from the due date of the annual return for that year, and longer if a case or appeal is pending. Electronic records are accepted if they're readable.

Can I continue my invoice numbers in the new POS?

Invoice numbers must be unique and consecutive within a financial year. The simplest approach is to start a new series with a different prefix in the new POS, ideally from the first day of a month, and keep the old series' records. Check with your accountant.

When is the best time to switch POS?

On a quiet weekday at the start of a month, away from festivals and weekends. Starting at the beginning of a month keeps GST reporting clean, with each month's sales in one system.
