The cheap bookkeeper. Where the bill really lands.
The quote is low, the books get "done", the annual accounts appear. For a while, nothing breaks. Then something asks a question — IRAS, a bank, a buyer, a GST auditor — and the answer has to be rebuilt from bank statements at a rate that makes the original saving look small. Here is where the cost of cheap bookkeeping actually shows up, in the order we usually see it.
In this article
Missed deductions
A bookkeeper who only records what the bank statement says will code a director’s personal expense as company cost (not deductible, and now a problem) and miss the business cost the director paid from their own card (deductible, and now lost). Capital allowances go unclaimed because there’s no asset register. Grants the company was eligible for are never mentioned because nobody was reading the numbers, only entering them. None of this shows up as an error. It shows up as tax that didn’t need to be paid.
GST claimed on faith
Every purchase with a GST line gets claimed. Whether the supplier was actually registered, whether the invoice is a valid tax invoice, whether the expense is even allowed for GST purposes — nobody checked. IRAS does check, on audit, and it goes back years. Disallowed input tax plus penalties is the single most expensive line we’ve seen a cheap engagement produce. The proper hand asks five questions before any line goes into a GST return; the cheap one asks none.
The tell: ask your bookkeeper what they do when a receipt is missing. "Claim it anyway" and "ignore it" are both the wrong answer. "Ask you" is the right one.
The year-end reconstruction
Cheap bookkeeping is often quarterly or annual data entry. By the time the accounts are prepared, the person who knows what a transaction was has forgotten. So revenue is booked when cash arrived rather than when it was earned, unpaid supplier bills vanish, and the profit figure is wrong in both directions. The tax computation is then built on that wrong number, and the ECI you filed early on the same books was wrong too. Reconstructing a year properly costs more than keeping it properly would have.
When the bank asks
Banks, especially for foreign-owned companies, ask for management accounts and explanations of transactions. A buyer doing due diligence asks harder. A set of books that can’t answer "what was this payment?" within a day reads as a red flag, and a red flag at a bank can mean an account review or a frozen facility. We’ve had clients come to us with a bank deadline and books that needed a fortnight of forensic work first. The bookkeeper was cheap. The fortnight wasn’t.
What to check before you hire
Who actually does the entries, and do they understand your business or just your bank feed? How often do the books get done — monthly, or "before the deadline"? Will they read the numbers back to you, or just file them? What’s their process for GST claims? And will they flag when something looks wrong, even if it’s awkward? Price matters, but it’s the last question, not the first. We’d rather be the bookkeeper who tells you your profit looks odd in March than the one who’s cheapest in January.
