Businesses don't usually fail dramatically. They get slowly squeezed by things too small to notice individually — each one forgettable, all of them together significant.
The nine leaks
Go through these honestly. Most small businesses have four or five running at once.
1. Invoices sent late
Every week between finishing a job and invoicing is a week of your money in someone else's account. It doesn't feel like a loss because it arrives eventually — but the cash flow cost is real.
2. Invoices never chased
The awkwardness of chasing means some money is quietly written off. See chasing invoices politely.
3. Work done and not charged
The extra bit while you were there. The call-out that turned into an hour. Individually generous, collectively expensive.
4. Quotes never followed up
See the jobs you lose without knowing. Probably the largest leak on this list.
5. Prices that haven't moved
Costs rose. Your prices didn't, because raising them is uncomfortable. Every month at the old price is a margin you've chosen not to have.
6. Subscriptions you don't use
Worth an audit — most businesses find something. Small monthly amounts are designed not to be noticed.
7. Repeat customers who drifted
They didn't leave, they forgot. See your best customers haven't heard from you.
8. Slow replies losing enquiries
See the cost of being slow to reply.
9. Your own unpaid hours
The biggest and least visible. Every evening spent on admin is unpaid labour propping up the business — it doesn't appear in any account, but it's real. See what your time is worth.
Why leaks beat disasters: a disaster gets your full attention and gets fixed. A leak gets absorbed. You adapt, you work a bit later, you accept it — and because each one is individually trivial, none of them ever reaches the top of your list.
The two-hour audit
Take the list above. For each leak, write down roughly what it's costing you per month. Guess if you have to — a rough number beats no number.
Then add them up. That total is what you're currently paying for not having got round to things, and it's usually enough to reorder your priorities.
Fix the ones that need no bravery first
Some fixes require difficult conversations — raising prices, charging for extras, chasing a slow payer. Those are worth doing but they'll take longer to get to.
Start with the ones that just need doing: invoicing promptly, following up quotes, cancelling unused subscriptions, contacting past customers. These need no courage, only time — which is exactly why speeding up the writing they involve matters. When a follow-up takes two minutes instead of twenty, it happens.
Then set a reminder
Leaks reopen. Put a recurring note in the diary — quarterly is plenty — to run through this list again. Fifteen minutes, four times a year, to check nothing has started dripping again.

What are the most common money leaks in a small business?
Invoices sent late or never chased, work done and not charged, quotes never followed up, prices that haven't risen with costs, unused subscriptions, repeat customers who drifted, slow replies losing enquiries, and your own unpaid evening hours.
Why don't business owners fix small leaks?
Because a disaster gets full attention and gets fixed, while a leak gets absorbed. You adapt, work a bit later, accept it — and because each one is individually trivial, none ever reaches the top of the list.
How do I audit my business for leaks?
Go through the common leaks and write down roughly what each costs per month — guess if you must, since a rough number beats none. Add them up. The total is what you're paying for not having got round to things, and it usually reorders priorities.
Which leaks should I fix first?
The ones needing no bravery — invoicing promptly, following up quotes, cancelling unused subscriptions, contacting past customers. Price rises and charging for extras need difficult conversations, so they'll take longer to get to.
