Payslips for commission earners: what to confirm a provider handles

You've just hired your tenth salesperson on a commission-plus-base model, and your basic spreadsheet system is starting to creak. Each month feels like a mini audit: hunting for the right sales figures, working out bonuses, recalculating tax withholding, then manually crafting each payslip. The risk is real—a wrong number on one slip costs trust, triggers payroll query emails, and eats your time. Time to hand this over. But before you ring someone, you need to know what questions separate a payroll provider who truly understands commission payroll from one who'll fumble it.

Why commission payslips demand a different skill set

Commission earners don't clock a fixed weekly or monthly wage. Their earnings land in bands—a guaranteed base, plus variable commission tied to real-time sales, targets, or performance thresholds. Some months they earn 120% of their base; others, maybe 85%. A standard payroll system built for salaried staff often can't flex enough to accommodate shifting gross amounts, changing tax brackets, and the knock-on effect on PAYE calculations. A provider handling commission payroll must track multiple income streams in parallel, apply the correct tax rates to each component, and ensure PAYE is calculated accurately before the final net pay lands in the employee's account. If they've only ever processed flat salaries, they'll quickly show their gaps.

What to ask about their commission calculation workflow

When you reach out, ask how they ingest sales or commission data. Do they require a spreadsheet upload from you each month, or can they integrate with your sales platform or CRM? The former is workable but leaves room for human error when transferring figures; the latter is cleaner. Ask whether they can handle tiered or multi-step commission structures—for example, 5% on sales up to R50,000, then 7% above that. Ask how they verify the accuracy of those calculations before payslips are generated: do they reconcile total gross pay against your source data, and do they flag anomalies? A competent provider will have a built-in quality step, not just rubber-stamp what you feed them. Also confirm whether they can apply retrenchment commission, clawbacks for client refunds, or other mid-contract adjustments without re-running the entire payroll.

Checking they'll handle variable tax withholding correctly

Because commission earners earn different gross amounts month to month, their PAYE liability shifts. An employee earning R25,000 one month and R35,000 the next sits in different tax brackets. A provider must recalculate PAYE for each individual payslip based on that month's actual gross, not apply a fixed withholding percentage. Ask them to walk you through a worked example: give them a commission earner's base salary and a hypothetical commission figure, and ask them to show you how they'd arrive at the PAYE amount on the payslip. If they pause or hedge, that's a warning sign. Also confirm that they apply the right tax tables—SARS updates thresholds regularly, and a provider handling multiple clients must stay current. Request that they note the tax calculation method or reference on the payslip itself, so employees can see the logic and trust the number.

Getting clear on integration and amendments

Before you book, establish how mistakes get fixed. Will they reissue a payslip if you spot an error in the commission figure, and how quickly? Ask if they can backdate payslips—not to distort records, but because commission sometimes lands late or gets adjusted retroactively once a deal closes or a refund processes. Confirm whether amendments can be handled within the same monthly payroll run or whether they require a separate correction payslip. Finally, ask how many users from your side can log in to submit commission data or raise queries, and whether they offer email or WhatsApp support for urgent month-end questions. A provider who hedges on these details will frustrate you when the first discrepancy appears.

When you're ready, look for providers on Strove who specialise in payroll processing and explicitly mention experience with commission or variable pay. Read their reviews closely for feedback from other SMMEs with salespeople or contract workers, and don't skip the reference call—a brief chat with someone they've already helped will tell you whether they truly own commission payroll or just manage it adequately.
