Cash Flow Management for Small Restaurants
Cash flow is the lifeblood of any small restaurant in Australia. Without it, you can't pay staff on ANZAC Day, cover a Bidvest invoice spike, or weather a quiet January. Most owners focus on profit margins—food cost, labour cost—but ignore the timing of money in and out. That's a mistake. A profitable restaurant can still collapse if cash doesn't flow the right way.
Why restaurant cash flow is different from other businesses
Restaurants operate on razor-thin margins. The Australian Hospitality Association reports that food costs sit around 28–32% of revenue, labour around 25–30%, and rent another 8–12%. That leaves 10–15% for everything else: utilities, suppliers, insurance, and actual profit. Unlike retail or services, you can't ask a customer to pay next month—the money hits your till (or your Eftpos machine) the moment they eat. But you've already paid your suppliers. That gap—between when you pay suppliers and when customers pay you—is where cash flow breaks.
Add Australia's penalty rate system, and the problem gets worse. A Melbourne cafe owner pays 50% more for a Saturday barista and 75% more on a Sunday. Christmas week? Double time. ANZAC Day? Double time. Your cash goes out fast during peak trading, even if revenue looks good on paper.
The supplier timing trap
Most Australian hospitality venues buy from Bidvest, PFD, or Countrywide on 7–14 day payment terms. That sounds reasonable until you realise you're paying for Monday's stock on the following Friday—but you won't serve half that stock until Wednesday. If you're running a 30% food cost, you need to turn over $3 in revenue to cover every $1 you spend on suppliers. If your cash is tied up in stock that hasn't sold yet, you're short.
The fix: negotiate staggered payment terms with your biggest suppliers. Most don't advertise this, but they'll do it. Ask Bidvest or your local PFD rep for split payments—50% on delivery, 50% seven days later. It won't cost you anything; they'll agree because they want your business. This alone can free up 5–7 days of working capital.
Track your cash conversion cycle—not just your P&L
Your profit and loss statement is a lie. It shows revenue and costs on the day they happen, but cash doesn't work that way. You might invoice a corporate event on a Monday, but they don't pay until the 15th of next month. Your GST is due quarterly, but you've already spent the money. Your superannuation is due by the 28th of the month following the quarter.
Calculate your cash conversion cycle: the number of days between paying suppliers and collecting cash from customers. For most restaurants, it's 15–25 days. A cafe with high card-payment turnover might be 5 days. A fine-dining restaurant with corporate events might be 45 days.
To calculate it:
- Days inventory outstanding (how long stock sits before it's used): typically 3–5 days for a restaurant
- Days sales outstanding (how long before customers pay): 0 for cash/card, 30+ for corporate clients
- Days payable outstanding (how long you hold supplier payments): 7–14 days for most venues
If your cycle is 20 days, you need 20 days' worth of operating expenses in the bank at all times. If your daily operating cost is $2,000 (wages, rent, utilities, supplier replenishment), you need $40,000 in reserve. Most small restaurants don't have this—and that's why they struggle.
The counter-intuitive tactic: delay your best customers
Here's something most owners won't tell you: sometimes you should slow down your high-revenue days to smooth cash flow.
If you run a restaurant in Sydney with a big Friday-night crowd, you're collecting $8,000–$12,000 in cash and card payments on Friday. But your supplier invoices from Bidvest hit your account on Wednesday. You're short on Wednesday, flush on Friday. By Monday, you're short again.
Instead: offer a small discount (2–3%) for cash payments on quiet Tuesday or Wednesday nights. Price your tasting menu or set menu 5% higher on Friday–Saturday, lower on Mon–Wed. Encourage corporate bookings on quieter nights with a group discount. This flattens your revenue curve and keeps your cash position stable.
It sounds counterintuitive because you're not chasing the biggest nights. But stable cash beats lumpy cash every time. A Melbourne bar owner who shifted 15% of Friday revenue to Thursday–Wednesday reported that she cut her overdraft usage by 60%.
Public holidays and penalty rates: plan 8 weeks ahead
Australia's public holiday calendar is brutal for cash flow. Christmas, Boxing Day, New Year's Day, Australia Day, ANZAC Day, Queen's Birthday, Melbourne Cup Day—each one triggers penalty rates of 50–100% extra on wages. A restaurant that normally pays $800 in wages for a night shift might pay $1,600 on Christmas Day.
Most owners react to this. They're shocked when the payroll bill lands. Instead, plan it.
Eight weeks before each major public holiday period:
- Calculate the extra wage cost (use your rostering software or a spreadsheet)
- Set aside that amount in a separate savings account—even if it's just $500–$1,000
- Plan your menu and pricing to absorb the cost (don't discount on public holidays; if anything, charge 10% more)
- Reduce discretionary spending that week (defer non-urgent maintenance, delay stock orders)
Christmas is the biggest: most venues lose 3–5 days of staff because people take leave, forcing you to hire casuals at double rates. Plan for July and August. ANZAC Day? Plan in February.
Invoice errors and supplier overcharges
A Countrywide invoice for a Brisbane restaurant might include:
- Stock you didn't order (a "suggested" item added by the sales rep)
- A price higher than the quote (new product, weight change, or just an error)
- A duplicate charge (Friday's order billed twice)
Most owners pay without checking. Over a year, that's 2–5% of your supplier spend—money you've already factored into margins. A restaurant spending $15,000 a month on suppliers is losing $3,600–$9,000 a year to errors.
The fix: audit 10% of invoices each week. Pick three random Bidvest or PFD invoices and cross-check them against your order confirmations and delivery dockets. If you find errors, ask for a credit. Most suppliers will grant it without pushback—they know it's their mistake. This alone can recover $200–$400 a month for a medium-sized venue.
GST and tax timing
GST is a cash-flow killer. You collect 10% from customers, but you don't get to keep it—it's due to the ATO quarterly. If you're doing $100,000 a month in revenue, you're collecting $10,000 in GST. But you've already spent that money. On the 28th of the month following each quarter, $10,000 leaves your account.
Most venues don't plan for this. They're surprised every quarter.
Set up a separate GST account. Every time you reconcile your till or Eftpos, transfer 10% of the day's revenue to this account. By the time the ATO bill is due, the money is already there. You won't feel the pinch, and you won't be tempted to spend it.
The same applies to quarterly superannuation: set aside 11.5% of your wage bill as you pay staff, not when super is due.
Where Calso fits in
Managing cash flow requires visibility—knowing what's coming in, what's going out, and when. Calso's supplier ordering and invoice auditing features flag overcharges and duplicate billing before they hit your account. By automating invoice checks and streamlining supplier payments, you reclaim time and money that would otherwise leak away. For venues serious about cash flow, that visibility is the first step.
