Lots of small businesses make a profit and still run short of cash. Customers pay late. Suppliers want payment on time. Wages and super go out every pay run, and a BAS bill arrives every quarter. The profit shows up in the reports, and the bank account is still low.
Bookkeeping is where you can see this happen. When your records are current, you know what customers owe you, what bills are coming and how much to put aside for tax. None of the habits below need special skills.
Why Bookkeeping Affects Your Cash Flow
Cash flow is the money moving in and out of your bank account. Profit is what is left after costs over a period, and it can sit in your reports for weeks before the cash arrives. A business can sell plenty and still be short, because customers pay in 30 days while staff and suppliers get paid sooner. Your bookkeeping records that timing gap.
Current records tell you who owes you money, which bills are due and what is in the bank today. With reliable small business bookkeeping you can plan payments around real dates. A monthly look at your reports will often show where cash is tied up, like unpaid invoices or slow-selling stock.
Common Bookkeeping Mistakes That Hurt Cash Flow
- Entering transactions weeks late, so the bank balance and the books do not match
- Sending invoices days or weeks after the job is finished
- Missing overdue invoices because nobody checks the aged receivables report
- Mixing personal and business spending in one account
- Paying bills too early, or paying the same bill twice
- Forgetting about GST and PAYG amounts, then facing a big BAS bill
- Guessing at expenses instead of tracking them
Reconcile Your Bank Accounts Often
Bank reconciliation means matching your books to your bank statement. Weekly is ideal, and monthly is the minimum. It picks up double payments, missing deposits and bank fees you forgot about. Errors are quicker to trace when they are recent.
Cloud software like Xero or MYOB makes reconciling faster. Bank feeds bring in transactions each day, and you check and approve them. Rules for repeat items, like rent or software subscriptions, save time and keep categories the same each month. Consistent categories make your profit and loss report easier to read.
Invoice on Time and Follow Up Late Payments
Late payment is a common cash flow problem for Australian small businesses, and it often starts with late invoicing. Send the invoice the day the work is done. For larger jobs, ask for a deposit or bill in stages. Put payment terms on every invoice, such as 14 days, with your bank details and a due date.
Then check your aged receivables report. It lists every unpaid invoice and how many days it is overdue. Look at it weekly and send a reminder a few days before each due date. If chasing payments takes too much of your week, an accounts receivable service can track invoices and follow up for you.
Ways to Get Paid Sooner
- Send invoices straight after the work is finished
- Offer online payment options such as card, bank transfer or direct debit
- Ask for a deposit before starting larger jobs
- Use progress payments on long projects
- Set up automatic payment reminders in your accounting software
Manage Bills and Supplier Payments
Timing matters on the payment side too. Paying every bill the day it arrives can leave you short. Paying late can cost you late fees and strain supplier relationships. Aim to pay on the due date. Most accounting software lists upcoming bills, so you can see the week ahead.
Check supplier terms once or twice a year. Some suppliers will extend from 14 to 30 days if you ask. Keep a weekly list of bills due and compare it with the income you expect. A tidy accounts payable process also stops duplicate payments and missed bills.
Set Money Aside for GST, BAS and Super
GST you collect is held for the ATO and paid through your BAS. PAYG withholding from wages works the same way. The BAS for the July to September quarter is due on 28 October 2026, and lodging through a registered BAS agent can give extra time.
Super has changed too. Since 1 July 2026, Payday Super means employers must get super into the employee’s fund within 7 business days of each payday, instead of once a quarter. The super guarantee rate is 12%. That cash now leaves your account every pay cycle, so build it into your forecast. Moving the GST part of each customer payment into a separate savings account also helps at BAS time. A payroll service can keep pay runs and super payments on schedule.
Build a Basic Cash Flow Forecast
A cash flow forecast lists the money you expect to receive and pay over the next 8 to 12 weeks. A spreadsheet is enough. Start with your current bank balance. Add expected customer payments, then subtract bills, wages, super, rent, loan repayments and tax. The result is your expected balance for each week.
Update it monthly with actual figures from your books. After a few months you will see patterns, such as slow seasons or clients who always pay late. If a shortfall shows up, you will know weeks ahead. That leaves time to chase invoices or speak to your bank.
