Cleaning business bookkeeping: profit by contract, not just in total

Profit lives at the contract level

Cleaning contracts fail quietly: the billing is fixed, the hours creep, and the company-wide totals stay healthy enough to hide it. So the unit of account in our cleaning books is the site, not the company. Every invoice, timesheet hour, and supply order carries a contract code, and the monthly report ranks contracts by direct margin — which is how you find the office tower that has quietly become your worst customer.

The mechanics are simple: locations or classes in QuickBooks Online, shifts tracked in QuickBooks Time or your scheduling app with a site on every entry, and supplier invoices captured through Dext. The discipline is the product.

Labour allocation: where the money actually goes

Payroll dominates the cost structure of a cleaning company, so contract profitability is decided by how honestly labour is allocated. Wages alone understate it: employer CPP and EI, vacation pay, statutory holiday pay, and WSIB premiums ride on every hour, and we load that burden onto site labour so each contract carries the true cost of staffing it.

Where cleaners are engaged as subcontractors rather than employees, we tag those payments separately, because the classification question carries real stakes — we cover it on our cleaning business payroll page.

Supplies: small numbers that compound across thirty sites

Chemicals, liners, and paper look immaterial invoice by invoice and become a genuine margin lever across a full route list. We track supplies per site each month, split consumables you absorb from consumables billed through to the client, and carry bulk purchases as stock on hand instead of dumping a quarter of chemicals into one month. When a site's supply cost bends upward, it usually means scope creep or product walking out the door — either way, you want to see the trend early.

Franchise systems: gross revenue, net deposits

Many janitorial franchises bill the customer centrally and remit the balance to you after royalties, brand-fund contributions, insurance, and admin fees. Record just the deposit and you lose the gross figure, the fee detail, and the correct GST/HST base all at once. We rebuild the gross from the franchisor's statement and post each fee to its own line, so you can weigh what the system costs against the work it feeds you — which is exactly the analysis you need at renewal.

When the franchisor is American, royalty payments raise Part XIII withholding and gross-up questions on the Canadian side. That layer is covered in our cross-border tax guide for cleaning businesses.

Cash, receivables, and keeping payroll safe

Commercial clients pay on net-30 or net-60 terms; your cleaners get paid every two weeks regardless. The books have to manage that gap on purpose: receivables aged by contract so slow payers are chased before they become write-offs, HST set aside as it is collected rather than discovered at filing time, and a simple payroll-coverage view showing how many payroll runs current cash supports. For what the full monthly close includes, see our bookkeeping services page.

None of this is exotic. It is ordinary discipline applied at the level where cleaning companies actually win or lose — the individual contract.
