The overheads audit: one afternoon to find where your business leaks money

Usual advice on cutting overheads goes: switch energy supplier, renegotiate the lease, buy cheaper paper. Sensible, but it misses the costs that never get their own line in the accounts.

The biggest ones often look like nothing at all. Ten minutes retyping an order. A subscription nobody remembers. A phone that rings out on a Saturday. Here's how to find them in an afternoon, with a pot of tea and last year's bank statements.

Leak 1: Hours lost to repetitive admin

Evidence on this is patchy, so take the numbers as a prompt rather than gospel. In a small March 2026 survey by HeyBRB, an automation consultancy, 167 UK owner-operators reported losing an average of 8 hours a week to repetitive admin. And 83% had never calculated what it costs them.

Do this: ask everyone to list repetitive jobs and rough weekly time. Then work out hours × hourly cost × 48 weeks. Include your own time, at the rate you'd charge a customer.

Leak 2: Software nobody uses

Most businesses have a graveyard of subscriptions, and the charges keep arriving. Fasthosts says that nearly 40% of workplace software goes unused, though it doesn't publish its method, so treat that as a warning rather than a measurement.

Do this: go through 12 months of card and bank statements and list every recurring charge. For each one, ask who uses it, when they last did and what would happen if it stopped. Look particularly for:

• seats for people who've left
• two tools doing the same job
• annual renewals coming up soon
• free trials that quietly became paid ones

Then look at the AI subscriptions in particular. Are three people paying separately for tools that do the same thing?

Leak 3: Enquiries that go nowhere

This one's a lost-income leak rather than a cost, but it hits profit all the same. You pay to attract an enquiry through your website, your ads and your reputation. If nobody answers, you've paid for nothing.

Do this: for one month, count every enquiry by phone, form, email and social. How many got a reply? How fast? What about evenings and weekends? Check your phone system's missed-call log, too. Most people find this one uncomfortable to read.

If out-of-hours calls are a real problem, there are ways to deal with them that don't involve hiring. The Beehive Legal AI Voice Agent, which we built at Just Creative People, answers the firm's out-of-hours calls, explains its services, books calls and passes leads to the CRM.

Leak 4: Doing things twice

Rework rarely shows up in the accounts. It looks like a customer's details typed into three systems, a brief that gets re-explained because nobody can find it, or a mistake caught at the end that could have been caught at the start.

Do this: follow one real job from enquiry to final invoice. Note every time information is retyped, every "where's that file?" and every "who was meant to do that?".

Then ask what would catch those problems earlier. Often it's something simple. For Cambridge Xyz, we built a Google Ads Campaign Checklist: clients complete their brief through a private link, the team signs off every check before and during a campaign, and everyone can see progress in one place. The saving comes from less chasing and fewer missed steps.

Leak 5: Marketing you can't measure

If you can't say which marketing brings in paying customers, you can't tell which part to stop.

Do this: list everything you spent on marketing last year. Next to each item, write how many enquiries and sales it brought. A blank space doesn't necessarily mean it isn't working. But it does mean you need proper tracking before you spend more, starting with asking new customers how they found you.

Leak 6: Chasing your own money

Hours spent chasing payment are a cost, and so is the cash tied up while you wait. The government's figures show businesses that spent staff time on it averaged 86 hours a year.

Do this: list what's overdue today and how long each invoice took to go out. Often the quickest win is invoicing sooner and setting up automatic reminders.

What it looks like when leaks are visible

Most of these leaks survive because nobody can see them. That's the thinking behind the dashboard demo we built at Just Creative People for Chilled Out Foods, a Stockport trade butcher. Online, trade and phone orders sit on one board, alongside stock and use-by alerts and overdue trade invoices, so the morning starts with what could be saved today.

Now rank what you found

Put everything in one table:

Then do these in order:

1. High cost, low effort. Do them this month. Cancelling subscriptions is usually here.
2. High cost, high effort. Pick one and plan it properly. This is where automation or a custom tool might pay for itself.
3. Low cost, low effort. Clear them when you have a spare hour.
4. Low cost, high effort. Cross them off and stop feeling guilty.

One warning

Cutting costs can cost you money if you cut what customers value. Automating a reply that should be personal, or dropping the check that catches mistakes, will show up later in your reviews and your repeat business. We'd take out the tedious work and keep the human bits.

Then do it again

Book the same afternoon in six months' time. Leaks come back, subscriptions creep in and processes drift. Run it twice a year and it starts to feel less like an audit and more like routine maintenance, which is exactly what it should be.
