How do I improve cashflow in a small business?
By Andrew Isaacs, CIMA Member in Practice ·
To improve cashflow in a small business, get invoices out faster, shorten customer payment terms, slow down the money leaving the business, build a rolling 13 week cashflow forecast, and keep a tight hold on stock and work in progress. The businesses that stay in control of cash are the ones that look at it weekly, not just when something goes wrong.
What cashflow actually means
Cashflow is the movement of money in and out of your bank account. It is not the same thing as profit. A business can be profitable on paper and still run out of cash, which is the single most common reason small companies fail. Profit is an accounting measure. Cash is real. When you are running a small business, cash is what pays the staff, the rent, HMRC and your suppliers.
The goal of cashflow management is simple. Make sure you always have enough cash in the bank to meet your obligations, with a buffer for the unexpected.
The five levers that improve cashflow
There are only five places you can pull to change your cash position. Work through each one deliberately.
1. Get paid faster
Most small business cashflow problems start here. Money is owed but not collected. Three things usually move the needle.
- Invoice the day the work is done. A delayed invoice is a delayed payment. If your systems let customers sit in a queue for two weeks before being invoiced, you have added two weeks to your debtor days before you have started chasing anybody.
- Shorten your standard payment terms. Moving from 30 days to 14 days on new customers compresses your receivables book significantly. If customers push back, offer a small early settlement discount rather than extending terms.
- Chase proactively, not reactively. Have a named person responsible for credit control. Send the invoice, send a polite reminder before the due date, and call if payment slips. Silence from you trains customers to pay you last.
2. Time the money going out
Paying suppliers too early quietly drains cash. Paying them too late damages relationships and can mean penalties. The right rhythm is to pay on terms, not before.
Review your supplier terms. Where terms are shorter than your customer terms, you are funding the gap yourself. That is fine if you have the cash, but it is worth knowing. For larger suppliers, ask for extended terms as a deliberate negotiation rather than stretching payments without warning.
3. Build a rolling 13 week cashflow forecast
A weekly forecast stretching 13 weeks ahead gives you enough visibility to act rather than react. You can see a cash pinch coming four or five weeks out, which is enough time to bring in a receipt, delay a discretionary payment, or draw on a facility.
Without a 13 week forecast, most small businesses are managing cash by looking at today's bank balance. That is driving by looking at the speedometer instead of the road.
4. Manage stock and work in progress
Every pound sitting in stock or in unbilled work in progress is a pound not in your bank account. For product businesses, review stock turn regularly and identify slow movers you can discount or clear. For service businesses, make sure work is billed as milestones are hit rather than at the end of a project. Long, unbilled engagements drain cash quietly and for months at a time.
5. Use finance facilities strategically
A short term cash gap is not automatically a problem. It becomes a problem only if you do not have the funding to bridge it. An invoice finance facility, an overdraft or a committed loan can smooth genuine timing gaps and let you take on work that would otherwise strain cash. The trick is to set the facility up before you need it. Banks are far more willing to lend to a business that is planning ahead than to one already under pressure.
Common mistakes to avoid
| Mistake | What happens | What to do instead |
|---|---|---|
| Measuring profit, not cash | You think the business is healthy while the bank balance shrinks | Monitor cash and profit separately every month |
| Invoicing in arrears | Payment is delayed by the gap between the work and the invoice | Invoice at the moment the work is done or the milestone is hit |
| No credit control | Debtor days drift upwards and some invoices are never collected | Assign ownership and chase on a schedule |
| Paying suppliers too early | You lose a cash buffer for no reason | Pay on terms and diarise the payment run dates |
| Forecasting in a spreadsheet nobody updates | The forecast becomes fiction within a fortnight | Refresh weekly against the actual bank position |
How quickly can cashflow actually improve?
Most small businesses that tighten invoicing and credit control see a measurable improvement in their cash position within four to six weeks. Reducing debtor days by seven days can release several weeks of working capital for a business with meaningful receivables.
The key is consistency. Cashflow improvement is not a project you finish. It is a weekly habit.
Common questions
What is the difference between cashflow and profit? Profit is income minus expenses across an accounting period. Cashflow is the actual movement of money in and out of the bank in real time. A business can be profitable and still run out of cash, usually because customers pay slowly or stock is tying up working capital.
How often should I review cashflow? Weekly at minimum. A rolling 13 week forecast updated every Monday, compared against the bank position, gives most small businesses enough visibility to act before a problem bites.
What debtor days should I aim for? Under 30 days is a reasonable target for most SMEs trading business to business on 30 day terms, though it varies by industry. Watch the trend as much as the number. If debtor days are rising, cash is deteriorating even if sales are not.
Is invoice finance a good idea? It can be. It releases cash against your debtor book, which smooths cashflow if you have slow paying customers. The downsides are cost and commitment. Compare it against an overdraft before committing.
When should I ask for extended supplier terms? As part of an annual or twice yearly review of your key suppliers. Ask before you need the flexibility, not once you are already behind.
