Cash Flow Tips for Small Business: 10 Ways to Improve It
Short answer: cash flow is the money that actually moves through your bank account, not the profit on paper. Practical ways to improve it: invoice the day the work is done, make paying you easy, follow up overdue invoices on a set day, put money aside for SARS every month and look 13 weeks ahead, so you see a gap coming.
A business can be profitable and still run short of cash. Sales on credit, a large stock order or a VAT payment can all leave the bank balance far lower than the income statement suggests. These 10 cash flow tips for small business owners work for any business, from a salon or a building contractor to a consultancy or an online shop.
Profit and cash flow are not the same thing
Profit | Cash flow | |
|---|---|---|
What it measures | Income less expenses for a period | Money in and out of the bank |
When a sale counts | When you invoice | When the customer pays |
A loan you receive | Not income | Cash in |
Equipment you buy | Spread over its useful life | Cash out on the day you pay |
Profit tells you whether the business makes money. Cash flow tells you whether you can pay salaries, suppliers and SARS this month. You need both.
1. Know your cash position every week
Reconcile your bank account in your accounting system at least once a week, so the balance you look at is real. Then check three numbers on the same morning each week: cash in the bank, what customers owe you and what you owe suppliers and SARS. When your bookkeeping is up to date in Xero, all three are on the dashboard.
2. Invoice the same day
Every day an invoice waits is a day added to when you are paid. Send it when the job is finished or the goods leave, not at month-end. For longer jobs, ask for a deposit upfront and invoice in stages, for example 50% when you start and 50% on completion.
3. Make paying you easy
Put your banking details and a clear payment reference on every invoice, and add a pay-now link for card or instant EFT. Show a due date ("Due 31 October") rather than a term such as "30 days", which customers count from different days. For regular clients, a monthly debit order brings the money in on the same day every month.
4. Follow up overdue invoices on a schedule
Chasing money works best as a routine, not a mood. Xero can send polite automatic reminders before and after the due date, and shows you when a customer has opened the invoice. A simple rhythm: a reminder 3 days before the due date, one on the day, one 7 days after, then a personal message.
5. Agree longer terms with suppliers
Ask your main suppliers for 30-day terms, or longer if you buy from them every month. Then pay on the due date, not the day the invoice arrives. Pay early only when an early-settlement discount is worth more than keeping the cash.
6. Keep stock lean
Stock on the shelf is cash you cannot spend. List your slowest sellers, order smaller quantities more often and clear old stock, even at a lower margin, to turn it back into cash.
7. Put money aside for SARS every month
VAT and PAYE are money you hold for SARS, not money you can spend. Each time a customer pays, move a fixed share into a separate tax savings account. For a VAT vendor, 15/115 of every VAT-inclusive standard-rated sale is output VAT. Most vendors account for VAT on the invoice basis, so that VAT is due to SARS when you invoice, even if the customer has not paid yet. The VAT on your purchases reduces what you pay over.
SARS payment | When it is due |
|---|---|
PAYE, UIF and SDL (EMP201) | 7th of the following month |
VAT (VAT201) filed on eFiling | Last business day of the month after the VAT period |
Provisional tax (February year-end) | End of August and end of February |
When these dates are in your forecast, they stop being surprises. See our VAT threshold guide if you are deciding whether to stay VAT registered.
8. Look 13 weeks ahead
A 13-week cash flow forecast is a simple table: your opening bank balance, the money you expect in each week, the money going out (salaries, rent, SARS, suppliers, loan repayments) and the closing balance. Update it every week. A gap you see 8 weeks out is a planning job; a gap you find on payday is a crisis. Xero's cash flow tools show invoices due and bills to pay, and can project your balance up to 180 days ahead.
9. Cut fixed costs that don't move with your business
Fixed costs stay the same in a quiet month. Review every debit order and subscription each quarter: software, insurance, data contracts and memberships you no longer use. Where you can, choose costs that rise and fall with your business turnover. One Percent Accounting's monthly fee, for example, is 1% of business turnover, from R79 a month excluding VAT, so in a quieter month the accounting fee is lower too. See Pricing.
10. Arrange funding before you need it
The best time to arrange finance is while trading is good, not in the week salaries are due. Lenders look at reconciled books, up-to-date VAT and tax returns and recent bank statements. Options include an overdraft, a short-term business loan, a line of credit or invoice finance, which is an advance against unpaid customer invoices. Interest on overdrafts and many business loans is linked to the prime rate, which is now 10.75% (what the prime rate rise means for your business). Registered South African businesses can also apply for short-term finance through our Bridgement Finance page; Bridgement is the lender and sets any offer.
Frequently asked questions
What is cash flow in a small business?
The money moving in and out of your business bank account over a period. Positive cash flow means more came in than went out.
What is the difference between profit and cash flow?
Profit counts a sale when you invoice it. Cash flow counts it when the customer pays. A business can show a profit and still be short of cash.
How often should I check my cash flow?
Once a week. Reconcile the bank first, then check cash on hand, what customers owe you and what you owe.
How much should I set aside for VAT?
15/115 of every VAT-inclusive standard-rated sale is output VAT. Less the VAT on your purchases, that is what you pay over to SARS.
What is a 13-week cash flow forecast?
A week-by-week table of expected money in and out for the next 3 months, updated every week, so you see a shortfall while there is time to plan for it.
