Tracking business expenses in South Africa: what to log and why it pays off

Most sole traders track what comes in. Far fewer properly track what goes out, and that gap usually costs money at tax time, whether that is VAT you never claimed back or deductions you cannot prove because the receipt is long gone.

Why expense tracking matters more than it looks

Every rand you spend running your business, rent, software subscriptions, materials, transport, is a rand that reduces your taxable income. If you are VAT-registered, some of those expenses also carry input VAT you are entitled to claim back from SARS. Miss the logging, and you miss the deduction and the claim, even though the money already left your account.

The problem is rarely that business owners do not know this. It is that tracking expenses by spreadsheet or shoebox falls apart the moment things get busy, and by the time the tax deadline arrives, half the receipts are unreadable or missing entirely.

What to log for every expense

A usable expense record needs more than an amount. For each expense, capture:

→

Description: What was actually bought or paid for, specific enough that you (or SARS) can tell what it was a year later.

→

Amount: The full amount paid, VAT-inclusive if the supplier charged VAT.

→

Category: A consistent bucket such as Rent, Software & Subscriptions, Transport, or Bank Charges, so you can see where money is actually going.

→

Date: The date on the invoice or receipt, not the date you got around to logging it.

→

VAT claimable: Whether the supplier charged VAT and you can claim the input tax back.

The VAT-claimable flag is the one most sole traders get wrong. If a supplier's invoice shows VAT separately (or is marked "TAX INVOICE"), the amount you paid includes input VAT you can deduct from what you owe SARS. If it does not, tick nothing: there is nothing to claim.

What this looks like on the Starter plan

The Expense Tracker on the Starter plan gives you exactly the fields above, organised by month. You log an expense once: description, amount, category, date, and whether it is VAT-claimable, and from there:

→Input VAT is calculated automatically. Tick "VAT claimable" and the 15/115 portion of the amount is worked out for you, no separate calculation needed.
→Expenses feed straight into your VAT Return Summary. Your bi-monthly SARS period shows output tax from invoices next to input tax from expenses, with the net amount payable or refundable, ready to use when you file your VAT201.
→Category totals show where money actually goes. A running breakdown by category makes it obvious if, say, software subscriptions have quietly become your biggest cost.
→Every entry is editable, with history kept. Fix a typo'd amount or wrong category later and the change is logged, not silently overwritten.

For most sole traders and single-business owners, this is already the difference between a confident VAT return and a guess.

Where Pro takes it further

The Pro plan does not change how you log an expense. It changes what that logged data can do for you once your business is bigger or more complex than a single income stream.

Starter

→ Unlimited expense logging
→ Automatic input VAT calculation
→ Expenses feed the VAT Return Summary
→ Category totals for one business

Pro

→ Everything in Starter, on every business you run
→ Expenses roll up into an Annual Financial Summary
→ Materials automatically split out as cost of sales
→ A draft Statement of Comprehensive Income for your accountant

The biggest jump is the Annual Financial Summary. On Pro, every expense you have already logged during the year is pulled into a Statement of Comprehensive Income for a financial year you choose, with Materials split out as cost of sales and everything else grouped as operating expenses. It is a draft for your accountant to work from when preparing your actual CIPC Annual Return, not a replacement for one, but it means the expense data you captured all year does not need to be reconstructed from scratch every February.

If you run more than one business under the same login, such as a side project alongside your main trade, Pro also keeps each business's expenses, categories, and totals completely separate, switchable from one dropdown in the dashboard.

If you run a separate PayFast-connected product

Pro's PayFast Transaction Sync pulls sales from your own PayFast merchant account straight into your Cash Flow Tracker, and now logs a matching PayFast Commission/Fees expense automatically too, whenever PayFast reported a fee on that sale. You do not need to log that one yourself.

Two things the sync still leaves for you: a refund or chargeback (excluded from the sync entirely rather than logged incorrectly as income) and PayFast's separate per-withdrawal payout fee, which is not tied to a single sale. Log the payout fee under its own PayFast Payout Fee category, so it stays distinct from the per-sale commission the sync already handles for you.

A habit worth building early

The single best time to start logging expenses properly is before you need the numbers, not during the week your VAT return is due. Log an expense the day you incur it, tick VAT claimable when it applies, and pick a category and stick with it. Six months in, the category totals alone are usually enough to spot a subscription you forgot to cancel or a supplier quietly costing more than expected.

Start tracking expenses on Starter

Log expenses, auto-calculate input VAT, and see it flow straight into your VAT Return Summary. Upgrade to Pro whenever you are ready for the Annual Financial Summary and multiple businesses.
