Cash Flow Is Not Profit, and Month Three Bites
A profitable month can still leave you short on rent. How timing on HST, payroll and deposits drains cash, plus a one-page weekly cash view you can keep.
Your accountant says you made money last month. Your bank account says you can't make payroll on Friday. Both are true, and neither one is a mistake.
This is the single most common thing that blindsides a new owner, and it tends to land around month three. Not month one, when you still have your opening float. Not month two, when the bills are still small. Month three, when the first real remittance comes due at the same time as rent, payroll, and a supplier who has quietly moved you off net-30.
This is not financial advice. I run a restaurant and a web studio, not an accounting firm. Talk to a bookkeeper or an accountant about your actual numbers. What follows is the plumbing — how the money moves, and a page you can keep on your desk so the timing stops surprising you.
Profit is about a period. Cash is about a date.
Profit answers: over these 30 days, did what I earned exceed what I spent? It smooths everything into one bucket. It doesn't care whether the money arrived on the 2nd or the 29th.
Cash answers: on Thursday, is there enough in the account for the thing that leaves on Thursday?
A month can be profitable and still have four days in it where the balance goes negative. Those four days are the ones that cost you NSF fees, a declined supplier payment, or a conversation with a landlord you'd rather not have. Profit is the scoreboard. Cash is whether you can keep playing.
Some of the money in your account isn't yours
This is the part that catches people hardest.
When you charge HST, you collect it. You don't earn it. It sits in your bank account looking exactly like revenue, because your bank doesn't label it. Then your filing period closes, and a large number leaves all at once. If you've been spending against that balance all quarter, the remittance feels like a penalty. It isn't. You were holding someone else's money and treating it as float.
Same story with payroll. The gross number on the schedule isn't what leaves your account. Net pay goes out on payday. The CPP, EI and income tax you withheld go out later, on a remittance schedule that depends on your size — often the 15th of the following month. So payday feels survivable, and then a second, smaller payroll bill arrives two weeks after you've forgotten about it. Add WSIB if you're covered, and employer-side contributions on top of what you withheld.
Tips, if you handle them, are in the same category. Money moving through you, not money belonging to you. If you're still sorting out how that works, we wrote about tip pooling in Ontario separately.
The practical fix is boring and it works: a second bank account. Every week, move the HST you collected and the source deductions you withheld into it. Don't look at that account. When the remittance comes due, the money is there and you feel nothing.
Money in arrives later than you think
Sales are not deposits. Between a customer tapping a card and the money being spendable, you have:
- Card settlement. Usually one to two business days, longer across a long weekend. Friday and Saturday sales often land Tuesday.
- Delivery apps. Typically a weekly payout, net of commission, on a fixed day. So a huge Saturday on an app shows up next week, minus a chunk. If you haven't audited which apps are worth their payout delay, start with which apps to keep and which to drop.
- Invoices. If you do catering, contract work, or B2B service, net-30 means net-30 at best. Realistically some customers pay on day 45. That is a month and a half of your cost being carried by you.
- Deposits and gift cards. Cash in your hand today for work you owe later. Good for cash flow, dangerous if you spend it and still have to deliver.
Meanwhile, money out arrives exactly when scheduled. Rent on the 1st, no grace. Payroll every two weeks, no grace. Insurance, loan payments, software subscriptions, all on dates set by someone else.
You can't change most of the out-dates. You can absolutely shorten the in-dates. Taking payment at the time of order instead of at pickup, requiring a deposit on bookings, invoicing the same day the job finishes instead of at month-end — each of those pulls cash forward by days or weeks without changing your prices.
Why month three specifically
The first two months hide the problem. You opened with cash on hand. Suppliers extended you terms to win the account. Your first HST period hadn't closed. Your first big payroll remittance hadn't landed.
By month three, all of those arrive at once, and a few new ones join them: inventory you're now restocking at full pace rather than drawing down opening stock, the end of any free trial software, and the realization that your slowest weeks still have the same rent as your best ones.
Nothing has gone wrong. The bills have simply caught up with the business. If you've mapped the dates ahead of time, month three is a Tuesday. If you haven't, it's a crisis.
The one-page weekly cash view
One sheet. Eight columns, one per week, covering the next two months. Paper is fine. A spreadsheet is fine. Not an app.
For each week, five lines:
- Opening balance. What's actually in the account on Monday morning.
- Money in. Expected deposits, placed in the week they'll actually land — not the week you earned them. Card settlements, app payouts, invoices you genuinely expect to be paid.
- Money out — fixed. Rent, payroll, loan payments, insurance, remittances. These are dated and non-negotiable. Write them in the week they hit.
- Money out — variable. Food, supplies, inventory, anything you control week to week.
- Closing balance. Line 1 plus 2, minus 3 and 4. That becomes next week's opening.
Then circle the lowest closing balance across the eight weeks. That single number is your real cushion, and it's the one to watch. If it's below one payroll run, you have a timing problem to solve now, not in six weeks.
Update it Monday morning, same sitting as your weekly operating numbers. If you don't have that habit yet, the three numbers to check every Monday pairs with this in about ten minutes total. And clean books make this sheet take minutes instead of an afternoon — a few bookkeeping habits do most of that work for you.
When a week comes up short
You spot it three weeks out. That's the point of the sheet. In rough order of what to try:
- Pull money in. Call the two unpaid invoices. Offer a small discount for payment this week if that's cheaper than the alternative.
- Push non-critical money out. Inventory orders can shift a few days. Equipment purchases can wait a month.
- Talk to suppliers early. A supplier told on Monday that you'll pay Friday instead of Wednesday is an administrative note. A supplier told after a failed payment is a credit decision.
- Never delay payroll or remittances. These are the two that create consequences you can't negotiate out of.
The tools that actually move the date
Most cash-flow fixes are operational, not financial. Online ordering that charges at order time instead of pickup. A booking page that takes a deposit when the appointment is made. A quote that goes out within the hour instead of the next day, so the catering job is yours and the deposit is in your account. A phone that gets answered so the order exists at all.
That's the overlap with what we build — see our services — but the principle stands with whatever system you're using. Any change that collects money sooner, with no extra work from you, improves your worst week. And your worst week is the number that decides whether month three is a Tuesday or a crisis.
