Why your bookkeeping is costing you more than you think - and how to fix it
Ask most founders what they think about bookkeeping, and you’ll get one of two answers.
Either: “It’s fine — someone handles it.”
Or: “I know it’s behind but I’ll sort it out when things quieten down.”
Both answers suggest the same thing: bookkeeping is seen as admin. A necessary evil. Something to keep on top of so the accountant doesn’t shout at you.
But here’s the thing. Poor bookkeeping isn’t just an admin problem. It’s a business problem — one that quietly costs you money, time, and confidence in your numbers every single month.
Let me show you what I mean.
The hidden costs of poor bookkeeping
When bookkeeping is behind or inaccurate, the costs are rarely visible on a spreadsheet. But they’re real.
You make decisions on bad data.
If your books are three months behind, your management accounts are three months behind. Which means the decisions you’re making today — about cash, about hiring, about pricing — are based on a picture of the business that no longer exists. That’s a risk most founders don’t consciously take, but end up taking anyway.
You spend time you don’t have firefighting.
Chasing receipts. Reconciling accounts before a VAT return. Trying to remember what a transaction from four months ago was for. Every hour spent on this is an hour not spent on running the business — and it’s usually the founder’s time, which is the most expensive time of all.
You lose money on VAT and tax.
Missed expense claims, incorrectly coded transactions, VAT returns filed on estimated figures. Poor bookkeeping is one of the most common reasons businesses pay more tax than they should — not through avoidance, but simply through inaccuracy.
You can’t see your margins.
Accurate margin reporting depends on accurate cost coding. If expenses aren’t allocated to the right project, client, or service line, your margin figures are meaningless. And if you can’t see your margins clearly, you can’t price confidently or spot the work that’s quietly losing you money.
You can’t get a loan, investment, or grant without it.
Any funder — bank, investor, or grant body — will want to see accurate, up-to-date financials. If your books are a mess, your options narrow significantly at exactly the moment you need them to be open.
What good bookkeeping actually looks like
Good bookkeeping isn’t complicated. But it does require consistency, the right tools, and clear ownership. Here’s what it looks like in practice:
What good looks like
Transactions recorded and reconciled within one to two weeks. A consistent chart of accounts that reflects how the business actually works. Clear coding of costs to the right project, client, or category. Someone with clear ownership of the process — and the time to do it properly.
Signs your bookkeeping needs attention
Not sure where you stand? Here are the most common signs that bookkeeping is becoming a problem:
- Your management accounts are regularly more than four weeks behind
- You’re not confident the figures in your accounts are accurate
- VAT returns are stressful and often filed close to the deadline
- You can’t easily see profit by client, project, or service line
- Your bookkeeper is also responsible for chasing invoices, doing payroll, and answering the phone
- Nobody has reviewed your chart of accounts in the last two years
- You’ve changed accountants recently and the handover was messy
If two or more of those rang a bell, it’s worth taking a proper look.
How to fix it — without starting from scratch
The good news: bookkeeping problems are almost always fixable, and you rarely need to start from scratch. Here’s the approach we take with clients:
First, get the books up to date.
This might mean a bookkeeping clean-up — going back through the last few months and making sure everything is coded correctly and reconciled. It’s often quicker than people expect.
Then, review the chart of accounts.
Make sure the categories you’re coding to actually reflect how the business works and give you the information you need. This is often where significant insight gets unlocked.
Put a process in place.
Decide who does what, by when. Get bank feeds connected. Set up a simple month-end routine. The best bookkeeping systems aren’t complex — they’re consistent.
Make sure the right person is doing it.
Bookkeeping done by someone without the right skills, time, or tools is often worse than no bookkeeping at all. If the person currently doing your books is stretched, it might be time to review the setup.
Where does your finance function actually stand?
Bookkeeping is just one of seven areas we look at when we assess the health of a finance function. The others — cashflow, management reporting, margin visibility, compliance, team and process, and grant management — all matter too, and they’re all connected.
Our free Finance Function Diagnostic covers all seven areas in around five minutes. You’ll get an instant, honest picture of where your finance function is strong and where the gaps are — so you know exactly what to focus on.
