How to organise your first commercial cleaning contract

This guide shows how to put those details into a short job brief that you and your customer can use. The completed example is fictional, so you can follow the process without opening a template or filling in blanks.

Confirm the work before promising a start date

Start with a walkthrough and the customer’s actual requirements. Record which areas need cleaning, what needs doing in each area and how often. Ask about opening hours, access, waste disposal, storage and who provides washroom supplies.

Keep the regular service separate from an initial deep clean or occasional work. “Clean the office” leaves too much open to interpretation. A list of areas, tasks and frequencies gives both sides something specific to check.

Use the commercial cleaning walkthrough checklist to gather the site details. If you still need to work out the time and price, the labor-hours calculator estimates time from your own task and support-time assumptions, while the guide to calculating a commercial cleaning bid explains pricing. The bid calculator can help you work through your own assumptions; it does not set the right price for every site.

Put the agreed details in one place

After the customer accepts your proposal, confirm the scope, price, service dates and practical arrangements in writing. Include the main contact for each side, any work excluded from the regular price, and what should happen when the customer asks for something extra.

Keep the accepted version. Record later changes separately so a request for extra work does not silently change the original agreement.

The commercial cleaning proposal template provides a completed example and a reusable Word document. It helps present the work and price; it is not a complete service agreement for every situation.

A completed first-contract brief

Prepare the first visit

Give the person doing the clean the agreed task list, visit time, access instructions and a contact to use if something prevents the work. Check that equipment, cleaning materials and customer-provided supplies will be available.

If you are doing the cleaning yourself, keep the same brief. It is easy to forget a detail discussed during the walkthrough once you are on site.

Confirm the first date and access arrangements with the customer. A planned visit is only useful if the cleaner can get in and knows which work was agreed.

Check what happened before closing the visit

Check the completed work against the scope. Use the commercial cleaning inspection checklist to record what was checked and anything that needs attention.

Write what happened in plain language. For example, if access prevented part of the clean:

Second washroom locked; not cleaned. Asked the office manager to arrange access.

That is an illustrative exception, not a record from a real customer. It identifies the room, the work that could not be done and the follow-up needed.

Do not mark a task complete because it was scheduled. Keep incomplete work visible and agree the next step with the customer. A recurring access problem may need a different visit time or a change to the agreed arrangements.

Invoice on the agreed basis

Match the invoice to the customer’s agreed pricing arrangement and the work completed.

In the Daybreak Studio example, November 2026 has five Mondays: November 2, 9, 16, 23 and 30. If all five visits are completed at CAD 120 each, the service subtotal is CAD 600 before tax. Four completed visits would total CAD 480 before tax.

Do not assume that a month always contains four weekly visits. Equally, do not use this per-visit calculation for a contract with an agreed fixed monthly fee. Keep cancellations, incomplete visits and extra work subject to the actual agreement, rather than automatically treating them as billable.

Make the invoice clear enough for the customer to connect the charges to the agreed service. Include the relevant service period or visit dates and use the payment terms you agreed.

Review the first few visits

Compare the planned time with the work actually required. Look for missing supplies, awkward access, repeated unfinished tasks or areas that need more attention.

Ask the customer whether the service is meeting the agreed expectations, using a contact method that works for them. If the site needs more time or a different task frequency, discuss the change and confirm the future scope and price. Keep the original accepted scope available.

Before the first visit

• Confirm the included areas, tasks and frequencies.
• Separate initial, regular and occasional work.
• Record the accepted price and billing arrangement.
• Confirm the first date, visit time and person doing the work.
• Arrange access and a contact for problems.
• Check equipment, materials and customer-provided supplies.
• Decide how you will check completion and follow up on unfinished work.
