Can I require payment upfront from a contractor client? Yes, and here is how

Upfront payment is reasonable in three situations. First, when the contractor is funding materials out of pocket and the materials are non-returnable or custom. Second, when the contractor has no prior payment history with the client. Third, when the job duration is long enough that the contractor's labour and overhead would be at risk if the client backed out mid-project. These three together cover the majority of residential remodel, commercial buildout, and field-service installation work.

What is not reasonable is asking for 100% upfront on a discretionary or low-trust transaction (a small repair, a quick service call, a one-off consultation). The signal that sends to the client is that the contractor either has cash-flow problems or does not trust them, and either signal damages the relationship before the work starts.

Three structures dominate the trades. The 50% deposit, 50% on completion (used for jobs under roughly $10,000 with a duration under 30 days). The 25/50/25 milestone structure (25% at signing, 50% at substantial completion, 25% at final inspection or punch-list close-out; standard for residential remodels and HVAC installs over $10,000). And progress billing tied to AIA-style schedules of values (used on commercial work over $50,000, where the architect or general contractor approves each draw).

The deposit amount should scale with materials cost and job duration. A roofing job with $8,000 in materials and 5 days of labour can reasonably ask for 60 to 70% upfront. A landscape design with $500 in materials and 60 days of labour might ask for 25%. Match the deposit to where the contractor's real money is on the line, and clients accept it without negotiation.

Introduce deposit terms at the proposal stage, not after the client has agreed in principle. The proposal document itself should state the payment schedule in the same section as the scope and price. A simple example: total project $14,500, payment schedule of $7,250 deposit at signing and $7,250 at substantial completion. Clients who sign that proposal have already consented to the structure; clients who push back at the proposal stage are surfacing a real concern that is better handled before the contract is signed than after.

For existing clients on a service-call basis, introduce deposits on the next quoted job (not retroactively on the current account). A common phrasing is that the standard for jobs over $5,000 is a 30% deposit, applied starting with the next project. This reframes the change as a standard business practice update rather than a vote of no-confidence in the specific client.

Deposits prevent the worst invoice outcomes; they do not prevent every overdue invoice. For the balance due at completion (the back half of the 50/50, or the final 25 of the 25/50/25), Syntharra runs the same day-3 first-party follow-up call that we run on standalone invoices. The deposit protects the contractor's downside; Syntharra collects the upside. The two together are how the best-paid contractors operate.
