Most of the financial problems we encounter in Sri Lankan SMEs could have been avoided. By the time a consultant gets called in, the books are usually a year behind, VAT returns are guesswork, and nobody is quite sure how much money the business actually made last quarter. The mistakes that lead there are consistent — and almost all of them are fixable before they become expensive.
These are the five we see most often in growing businesses across Colombo and the suburbs — small enough to be common, big enough to cost real money.
1. Treating director’s drawings as business expense
In family-run SMEs — which is most of them in Sri Lanka — the line between the owner’s wallet and the company’s bank account is the single biggest source of accounting trouble. Fuel for the family car, a renovation at home, a child’s school fee — all paid out of the business account and quietly booked as “office expense” or “general administration.” The numbers look fine for a year. Then the auditor disallows half of it, the assessable income shoots up, and the tax bill arrives.
Director’s drawings are not an expense. They’re a balance-sheet movement. If your chart of accounts doesn’t have a clean “Director’s Loan” or “Drawings” account in equity, this is the first thing to fix.
2. Not reconciling bank accounts monthly
The typical growing SME has three or four operating accounts — Sampath, Commercial, BoC for government counterparties, an HNB credit card. Nobody reconciles them. The accountant trusts the bank statement, the bank statement trusts the system, and a whole class of issues (duplicate payments, missed receipts, suppliers paid twice) hides in the gap. Monthly bank reconciliation isn’t bookkeeping hygiene — it’s the only control most SMEs have against cash leaks.
3. Forgetting that WHT is a receivable
Every Sri Lankan business invoicing other VAT-registered businesses gets withholding tax deducted at source. That WHT is recoverable against your final income tax liability — but only if you actually track it as a receivable and chase the WHT certificate from each customer.
We’ve seen growing businesses with LKR 4–5M of unclaimed WHT sitting on the table because nobody booked it as an asset. It was just “tax deducted” in the back of the ledger. If your accounting system isn’t showing a running WHT-receivable balance by customer, that’s money you have already paid that you may never recover. (The personal-tax side of WHT also moved this year — see our note on Sri Lanka personal income tax for 2025-26.)
4. Booking inventory at invoice cost only
If you import anything — raw materials, finished goods, packaging — the cost on the supplier’s invoice is not your real cost. Freight, clearing, port charges, demurrage, and Customs duty can add 20–30% on top, and in some categories much more. SMEs routinely book stock at landed FOB cost and treat the rest as “import expense.” The result: gross-margin reports that overstate profitability across the whole catalogue, and pricing decisions made on numbers that aren’t real.
Proper landed-cost accounting takes one extra step per shipment. The payoff is knowing which SKUs are actually making you money.
5. Filing VAT returns without reviewing journals first
Most accounting software will generate a VAT return at the click of a button. That’s exactly the problem. If a transaction was posted to the wrong tax code three weeks ago, the return propagates the error. The IRD doesn’t care that the system generated the number — the liability sits with you.
A 30-minute pre-filing review — checking that input tax ties to actual purchases, that output tax matches sales, and that exempt and zero-rated transactions are correctly classified — is the difference between a clean assessment and a notice from the Department three years later.

None of these are exotic. They’re the basics that get skipped when a business is growing fast and the finance function hasn’t caught up. If any of them feel familiar, the cheapest time to fix them is now — before the audit, before the bank facility renewal, before the tax assessment.
