Just because a place has a line doesn’t mean its bank balance is healthy. Even with many customers, mismatches between card revenue deposit dates and ingredient payment dates can create cash shortages. The visible queue and the bank balance are different problems.
Making a closure decision based on feeling alone leads to mistakes. It’s more practical to first look at dates: bank balance, card-revenue deposit dates, ingredient payment dates, and rent day. These dates need to align so you can cover wages, ingredient costs, and rent.
Another common trap is confusing revenue with profit. Average spend per customer and customer count produce revenue. But if costs—food cost, delivery commissions, labor, and waste rate—are high, the actual money left is much smaller.
Timing is especially critical for cash flow. Card revenue may be deposited weekly or every 15 days, while ingredient bills are withdrawn in bulk on suppliers’ payment dates. Rent and wages are fixed outflows; if their dates coincide, the account can quickly go negative.
The numbers to check on-site can be narrowed to a few. Create a one-month projected bank-balance schedule and align it with expected card-deposit dates and ingredient-payment dates. Add rent and payroll dates, then mark shortfall days to reveal hidden risks.
For example, consider a small restaurant focused on lunch. If it averages 80 customers a day with an average spend of 9,000 won, daily revenue is around 720,000 won. But if 70% of sales are by card and card deposits come once a week, the actual cash flowing into the account will be concentrated several days later.
If ingredient payments are due every Monday and rent is on the 1st of the month, the beginning of the month can easily see cash shortages. Increasing delivery to raise average spend won’t help much if delivery commissions are 15%—net profit won’t rise as much as expected. Calculating this shows how a popular shop can still end up with a negative bank balance.
The inspection standard is simple. Map one month of cash flow by date and check the gaps between deposit and withdrawal dates. Estimate expected deposits by multiplying customer count, average spend, and the card ratio.
Subtract cost ratio, commissions, wages, and waste rate from that to see the actual cash remaining.
Actions must be realistic and practical. First, compare the current bank balance with fixed outflows for the next 15 days. If you see a shortfall, look for ways to shift payment timing—negotiate supplier payment dates, change to a card-settlement provider with faster deposit, or temporarily adjust labor payouts.
Menu trimming can be considered afterward; it’s not necessarily the first step.
There are small changes that produce immediate effects. Negotiate with ingredient suppliers to move payments to month-end, or switch to a card processor that pays out faster. Temporarily reduce high-commission delivery channels and focus promotions on in-store repeat visits to increase cash inflow.
The secret of a busy shop is the combination of menu, psychology, visual appeal, and operations. Judging closure is similar: before relying on qualitative judgment, check 2–3 months of cash flow with numbers. If a recurring deficit pattern persists, prepare for a change of business type or an exit route.
Deciding based on numbers makes next steps clearer than holding on emotionally.
The one thing to check at your shop today is the gap between card-revenue deposit dates and ingredient payment dates. Comparing that gap to your bank balance will show the exact timing when the account could go negative.
Frequently asked questions
Why does my bank account not grow even though my restaurant has lines?
A line and the bank balance are separate. If a high share of sales are by card and deposits are delayed, or if ingredient-payment days and rent days overlap, cash can run short. Also check hidden costs like food cost, delivery commissions, and waste rate.
Are there short-term ways to improve cash flow?
Adjusting payment timing is the fastest. Negotiate supplier payment dates, switch to a card-settlement provider with faster payouts, or temporarily reduce high-commission delivery channels to generate short-term cash inflow.
What period should I look at to judge closure by numbers?
Collect at least three months of numbers. Compare daily bank flow with sales, cost of goods, labor, and fixed costs to see whether a recurring deficit structure exists.
