7 Ways to Improve Business Cash Flow

Most businesses chase invoices too late and too politely. A three-stage sequence — polite nudge at 7 days, firm reminder at 14 days, Letter Before Action at 21 days — gets results. Most customers pay within 48 hours of a Letter Before Action. It costs nothing. It requires discipline.

If you're sending one vague email after 30 days and then nothing, you're leaving cash on the table. The money is already yours — you're just not collecting it efficiently.

If you're invoicing on 60-day terms because that's what the customer asked for, ask yourself: did you negotiate, or did you just agree? Many businesses accept the first terms offered without pushback. Shorter terms — 30 days, or even 14 for smaller jobs — can cut the gap between doing the work and getting paid in half.

Ask for deposits. Stage payments on longer jobs. Credit-check customers before giving them 60-day terms. These are all standard commercial practices — not aggressive, just sensible.

Invoice finance lets you get up to 90% of your invoice value within 24 hours of raising it, rather than waiting 30, 60, or 90 days. The finance provider advances you the cash, then collects from your customer when they pay. You receive the balance (minus fees) once they have settled.

It works best for businesses with consistent B2B invoicing and customers with good credit. Typical cost is 1–4% of annual turnover depending on sector, volume, and provider. Not free — but it eliminates the waiting entirely.

Cash flow is a two-sided problem. You can work on what comes in — or you can work on what goes out. If you are paying suppliers on 30-day terms but your customers take 60, you have a structural mismatch. Ask suppliers for 45 or 60 days. Many will say yes, especially if you are a reliable customer.

Early payment discounts work the other way too: if a supplier offers 2% off for payment within 10 days, think carefully — 2% over 20 days is roughly 36% APR. Sometimes it makes sense, sometimes it does not.

Subscription software, insurance you've never claimed on, card processing fees that were competitive three years ago — most businesses have outgoings that no longer make sense. A quarterly review of bank statements for recurring items catches more than you expect.

This will not solve a structural cash flow problem, but it reduces the pressure while you work on the bigger levers. Even £500/month in unnecessary outgoings is £6,000 a year.

A business overdraft or revolving credit facility lets you draw down what you need and pay back when cash comes in. Unlike a term loan, you only pay interest on what you use. It is not a solution to structural cash flow problems — it just gives you breathing room.

Rates vary widely. Bank overdrafts are typically the cheapest option but hardest to get without a relationship. Alternative lenders offer revolving credit facilities more flexibly but at higher rates. Shop around. Always understand the rate before drawing down.

If cash flow has become a debt problem — you are missing loan repayments, falling behind on PAYE, or using personal savings to keep the business going — the right move is to talk to someone independent before you take on more credit.
