When (and how) to switch payroll software

Most small businesses do not choose their payroll method so much as inherit it. You started with one or two staff, opened a spreadsheet, and the spreadsheet stuck around long after the team grew. Or you handed the whole thing to a bureau and only notice it when an invoice arrives or a payslip turns out wrong. Either way, payroll quietly becomes one of those jobs that takes longer, costs more and worries you more than it should.

This guide is for the owner who suspects it is time for a change but is nervous about the disruption. We will cover the clear signs you have outgrown your current setup, what to look for in a replacement, the best time of year to make the move, and a practical migration checklist so you can switch without dropping a single pay run or missing a SARS deadline.

The signs it is time to switch

You rarely wake up one morning and decide to change payroll systems. Instead, the friction builds. Here are the signals that tend to mean the cost of staying put has overtaken the cost of switching.

• Errors keep creeping in. A formula gets dragged one cell too far, a rebate is applied to the wrong employee, or PAYE is out by a few rand every month. Small mistakes compound into big reconciliation headaches at year-end.
• It eats your time. If a single pay run swallows half a day of copying, checking and re-checking, that is time not spent running your business.
• You are missing or rushing deadlines. The EMP201 is due by the 7th of the following month. If you are scrambling every month, the system is working against you.
• Your payslips are not compliant. A spreadsheet printout is not a BCEA-compliant payslip. If yours is missing required fields, you carry a real legal exposure.
• The cost no longer makes sense. A bureau that was fine for two staff may feel expensive at ten, especially if you are still doing half the legwork yourself.
• Nobody can cover you. If only one person understands the spreadsheet, a single sick day can hold up everyone's pay.

What to look for in a replacement

Once you have decided to move, the temptation is to grab the cheapest or most familiar option. Resist that. Payroll is a compliance job first and a convenience second. Hold any candidate against this short list before you commit.

This is the bar OrigamiPay is built to clear: it does the PAYE, UIF and SDL maths against the current tables, produces BCEA-compliant payslip PDFs, and pre-fills your EMP201 totals so the monthly declaration is a review rather than a rebuild. If you want a refresher on how those three deductions fit together, see PAYE, UIF and SDL explained.

The statutory figures your system must get right

Whatever you switch to, it has to handle the 2025/26 numbers correctly. These are the headline figures any compliant system should apply automatically.

PAYE is the part most spreadsheets get wrong, because it is not a flat percentage. It is worked out by annualising the month's pay, applying the sliding bracket table, subtracting the rebates and any medical scheme credits, then dividing by twelve. Here is the table your system should be applying.

The best time to switch

You can move payroll providers at any point, but two moments make it far simpler.

Start of the tax year (1 March)

The South African tax year runs from 1 March to 28 February. Switching on 1 March is the cleanest option because everyone starts the new year with zero year-to-date figures. There is nothing to carry across, and your old system handles the full prior year's EMP501 reconciliation and IRP5 certificates.

Start of a calendar month

If you cannot wait for March, switch at the start of a month. Payroll is a monthly cycle, so a month boundary gives you a clean cut-off. The one thing you must bring across is each employee's year-to-date totals, so PAYE continues to annualise correctly. Avoid switching mid-cycle, which forces you to split a single month across two systems.

Your migration checklist

A switch goes wrong when it is rushed. Work through these steps in order and the move becomes routine rather than risky.

1. 1Gather your employee data. Full names, occupations, ID numbers, tax numbers, bank details, start dates, pay rates and pay frequency. Get it clean and complete in one place before you load anything.
2. 2Capture the year-to-date figures. If you are switching mid-year, you need each employee's earnings, PAYE, UIF and any other deductions already paid this tax year. This is what keeps PAYE annualising correctly. If you switch on 1 March, you can skip this.
3. 3Confirm your statutory registrations. Make sure your PAYE, UIF and (if applicable) SDL reference numbers are correct and to hand. Remember SDL only applies once your annual payroll exceeds R500 000.
4. 4Set up and load the new system. Enter your company details and employees, then your opening year-to-date balances.
5. 5Parallel-run one cycle. Run one pay period in both the old and new systems at the same time and compare. The numbers should match to the rand.
6. 6Verify line by line. Check net pay, PAYE, UIF, SDL and the EMP201 totals against your old output. Investigate any difference before you go live.
7. 7Issue payslips and file as normal. Once the parallel run ties out, hand staff their new payslips, submit the EMP201 by the 7th, and retire the old system.

After the switch

Switching is a one-off effort; the payoff is every month afterwards. Once you are settled, the rhythm is simple: capture any changes, run the cycle, hand out compliant payslips, and submit the EMP201 by the 7th of the following month. The maths, the tables and the paperwork should largely look after themselves, which is the whole point of moving in the first place. Keep your three years of records in order and the heavy lifting is done.
