Financial tips for SMEs: ten habits that keep cash, margin and financing under control

A business that has traded for years rarely gets into trouble for lack of customers. It gets into trouble when growth, a large customer on long payment terms or a jump in costs absorbs more cash than the profit and loss account shows. The financial tips for SMEs on this page are written for that stage: you have staff, a bookkeeper, a bank facility and annual accounts, and you want earlier warnings and better decisions. If your business is still young, start with the ten financial tips for new business owners; this page builds on those habits rather than repeating them. The principles work in any country and any currency.

Ten financial tips for SMEs that already trade

1. 01

   Roll your cash flow forecast forward every week

   An annual budget is set once; a rolling forecast moves with the business. Keep a weekly view of the next thirteen weeks with every known receipt and payment: payroll, VAT or sales tax, tax instalments, rent, loan repayments and large supplier invoices. Behind it, keep a monthly view of the next twelve months that you extend every month. Compare last week's forecast with what really happened: a gap that keeps coming back points to a wrong assumption, usually the date customers actually pay.

2. 02

   Run credit control as a process, not a chase

   Check new customers before you give credit, set a credit limit per account and state the payment term on every quote and invoice. Review the aged debtor list (unpaid invoices sorted by how long they are overdue) every week and follow a fixed ladder: a reminder before the due date, a phone call soon after it, a stop on new work after that. In the EU and the UK, payment terms agreed between businesses are normally capped at 60 days, with longer terms allowed only if expressly agreed and not unfair to the supplier (source: EUR-Lex, February 2011; GOV.UK, October 2026). Other countries have their own rules, so check yours.

3. 03

   Size your buffer to your real risks

   For an established firm the buffer is cash plus the undrawn part of a committed credit facility, not cash alone. Size it on what could actually happen. How many weeks of fixed outgoings does it cover? Would it survive your largest customer paying two months late? What happens if the bank reduces the facility at renewal? Write the target down and refill the buffer after you use it.

4. 04

   Know your margin per customer and per product

   The gross margin of the whole business hides the mix. Calculate the contribution (revenue minus the costs that move with it) per product group and per customer, then add the cost to serve: small orders, rush deliveries, custom work, returns and long payment terms. Usually a few customers or products earn most of the profit and some cost money. Activity-based costing shows how to assign overheads to the activities that cause them, so the comparison is fair.

5. 05

   Finance each need with the right term and product

   Match the term to the life of what you finance, and the product to its pattern. Machinery suits asset finance or a term loan over its useful life; seasonal stock and growing receivables suit a revolving facility or invoice finance; a permanent rise in working capital needs long-term money, not an overdraft that is always drawn. Spread maturities so that not every loan needs refinancing in the same year, and read the covenants (financial conditions in the loan agreement, such as a minimum equity ratio) before you sign. Where collateral is short, see grants and public funding.

6. 06

   Learn the warning signs that cash is getting tight

   Tight cash shows in behaviour before it shows in the accounts. The overdraft no longer returns to zero, debtor days creep up month after month, suppliers or the tax authority are paid later than agreed, customer deposits fund running costs, and the headroom against your loan covenants shrinks. Agree in advance which sign triggers action and who acts, so nobody waits for the year-end accounts.

7. 07

   Close the month fast and read one page

   Management accounts only help if they arrive while you can still act, ideally within two weeks of month-end, with accruals for large costs so the result does not depend on when invoices arrive. Put one page on top: revenue and gross margin against budget and last year, overheads, operating result, cash, debtor days, stock and the order book. A few times a year, the profit and cost benchmark shows how these figures compare with your industry.

8. 08

   Review prices every year and write it into contracts

   Costs rise in steps; prices often follow late or not at all. Plan a fixed annual price review based on your cost price and the market, and add a price adjustment (indexation) clause to framework agreements and long contracts, linked to a published index or to named cost items. Look at discounts and free extras too: they grow without anyone deciding it, and removing old ones is often the quickest gain.

9. 09

   Manage working capital in days

   Working capital (the money tied up in stock and unpaid customer invoices, minus what you owe suppliers) grows with revenue. Track it in days: debtor days, stock days and creditor days. Together they give the cash conversion cycle, the time between paying for materials or labour and receiving the customer's money. Every day off that cycle releases cash without new borrowing.

10. 10

    Keep your bank informed before you need it

    Banks lend more readily to customers they understand. Send your annual accounts and a short update without being asked, meet your relationship manager once a year and share your forecast before you need extra credit. Report setbacks early, together with your plan, and know when each facility is up for renewal. A second financing relationship, such as an asset finance or invoice finance provider, makes you less dependent on one lender.

How to free up cash in an established business: a worked example

Vellmar Technical Services installs and maintains climate systems in office buildings and employs thirty-five people. Its overdraft was fully drawn, and the owner planned to ask the bank for an extra €200,000. The rolling forecast showed why: revenue had grown to €4,200,000, but two new property management customers paid after about ninety days, invoices for maintenance work went out only at month-end, and the parts warehouse had grown with every new contract.

Fictitious Firmfocus example, amounts rounded to hundreds. The logic works in any currency.

Vellmar invoiced each job on completion, moved maintenance contracts to direct debit and agreed sixty-day terms with the two property managers. It returned slow-moving parts to the supplier and set reorder levels per van. The €250,800 released was more than the €200,000 the owner had wanted to borrow. Vellmar did not pay its own suppliers later, which would only have moved the problem. It kept the overdraft as a buffer and sent the new forecast to the bank, which made the next renewal a short conversation.

Cash getting tight? What to do first

• Update the thirteen-week forecast: with realistic payment dates, so you know how deep and how long the gap is.
• Call your largest overdue customers: personally, with a concrete proposal such as a part payment now and a schedule for the rest.
• Talk to the bank before the limit is reached: bring the forecast and the measures you are taking.
• Contact the tax authority before a deadline passes: ask whether a payment arrangement is possible; asking afterwards leaves fewer options.
• Pause spending you can postpone: investments, hiring and stock building.
• Involve your accountant early: an outside view separates a timing problem from a structural one.

Small firm or larger SME: where to put your effort

Pitfalls

• Growth without a cash plan: more revenue means more receivables and stock before it means more cash.
• An overdraft that is always drawn: it is long-term debt in disguise, and the bank can reduce it at short notice.
• Funding growth by paying suppliers late: it costs you discounts, priority and goodwill.
• Trusting the average margin: a loss-making customer or product hides easily in the total.
• Surprising the bank: late bad news costs more trust than the news itself.
