How to check a provider counts the sick-leave cycle correctly

When an employee takes sick leave, how it's counted matters. Count it wrong and you face back-pay claims, disgruntled staff, and audit red flags. Yet many small business owners discover mid-year that their payroll provider has been applying sick-leave rules incorrectly — sometimes for months. The good news: you can catch this before it becomes expensive.

Sick leave under South African labour law works differently from annual leave, and the details trip up many providers who handle it casually. The question isn't whether your provider *knows* the law — it's whether they're actually *applying* it correctly to your business's pay runs and records. Here's how to verify this.

Understand what "correct" looks like before you check

Sick leave accrues at a rate of one day per 26 working days worked. It doesn't reset on January 1st; it's a rolling entitlement that accumulates and carries forward. An employee can take it when genuinely ill, and employers can require a medical certificate after a certain threshold (often three consecutive days, though your policy may differ). What trips up providers is the *tracking*: whether they're counting working days accurately, whether they're handling partial days, and whether they're carrying unused balance forward correctly into the next cycle.

Before you call your provider, pull your own payroll records for the past six months. List one or two employees and manually check: How many working days did they work each month? How much sick leave did they take? What balance appears in your records now? Write this down. You're about to compare this against what your provider tells you.

Request a sample sick-leave audit from your provider

Email or WhatsApp your provider directly: ask them to pull a detailed sick-leave record for a single employee over the past six months. Request it in writing so there's a record. A competent provider will send you a breakdown showing accrual (days earned per month), deductions (days used), carry-forward balance, and any policy-specific rules applied. If they send you a vague summary or say "it's all in the system," that's a warning sign; ask them to export the detail into a spreadsheet so you can read it line by line.

When the report arrives, check it against your own records. Does the accrual rate match (one day per 26 working days)? When the employee took three days sick leave in June, are all three recorded and deducted? If they had unused balance in June, does it carry into July? If your records and theirs disagree, ask them to explain the discrepancy in writing. A trustworthy provider will walk you through it; a defensive or evasive one suggests they're not confident in their own system.

Also ask: "How do you handle employees who join mid-year or leave on notice?" Sick-leave accrual pro-rates, and errors here are common. Request a worked example showing how they'd calculate it for a new hire or a departing staff member. Their answer reveals whether they've thought this through or are winging it.

Check references and ask the hard question

If your provider gave you client references when you first engaged them, phone one or two and ask directly: "Have you ever spotted an error in how they count sick leave?" Don't ask softly; ask as though you expect it might have happened. Most will answer honestly. If they say, "Yes, we caught it when we reviewed our records," that's actually reassuring—it means the error was finite and correctable. If they say, "No idea, never checked," ask them: "Would you check now?" Sometimes a reference conversation prompts a client to verify their own records, which is useful intelligence for you.

Before you switch providers or ask for a full audit, run this check first. If the sample audit shows accuracy and your references are calm, you likely have someone competent. If the sample is messy or your references hesitant, it's time to dig deeper or consider moving on.

When you're ready to vet a new provider, use this same process as part of your selection. Ask them to walk through a sick-leave scenario before you hire them. Their answer will tell you whether this is genuinely part of their system or an afterthought. You can find verified payroll providers on Strove who specialize in leave administration; ask them for this same sample audit during the vetting stage, and compare the rigour of their responses.
