Ask for a deposit of 30 to 40 percent before starting, covering at minimum the cost of materials, and get the price confirmed in writing — even a simple WhatsApp message — before you pick up a single tool. Non-payment is almost never organised theft: it is a misunderstanding over price, a customer who changes their mind partway through, or simply the absence of any written commitment that makes refusing to pay easy. Here is how to structure every job so that risk nearly disappears.

This is not specific to one trade

Whether you are a plumber, painter, electrician or carpenter, the logic is the same: the more materials a job requires you to buy up front, the more a deposit protects your cash flow. A ten-minute unblock does not need one; a bathroom renovation absolutely does. Adjust based on what you are actually fronting, not a single fixed rule. These habits are worth stating clearly on your craftsman profile, where you can note your usual terms in your bio.

Why a deposit protects both sides

A deposit is not a sign of distrust towards the customer — it is mutual protection. It covers you if the customer cancels after you have bought materials. It commits the customer, who finds it harder to disappear having already paid something. And it removes an awkward conversation at the end: instead of negotiating the total once the work is finished and the leverage has shifted, the bulk of it is already settled before you even start.

How much to ask, and when

  • 30 to 40 percent on booking — the norm for most jobs, adjusted for trust and size.
  • The cost of materials, at minimum — if you are buying the materials, never front them from your own pocket without a deposit.
  • Staged payment on a large job — a third at the start, a third midway, the balance at the end. This stops you fronting weeks of unpaid work.
  • Never 100 percent before starting — even if the customer insists. A job paid in full before the first tool is picked up gives nobody an incentive to do it right or check it carefully.
warning

A signal worth noticing

A customer who flatly refuses any deposit at all, even 20 percent, on a job with real materials to buy, is telling you something. It is not always a problem — some people are simply cautious — but it is the moment to nail down the price in writing before committing.

A written agreement, even a simple one, beats unspoken trust.

The written record that changes everything

You do not need a formal contract to protect yourself: a WhatsApp message sent before starting, summarising the total price, what it covers, the deposit amount and the balance due, carries the same practical weight as a signed document. It fixes both sides' memory and prevents the classic "that's not the price we agreed" at the end. Make it a habit even with a customer you know well — that is exactly where misunderstandings cost the most, because nobody expects a disagreement.

What to do about a slow payer

Follow up early and without hostility — a polite message the day after the agreed deadline beats two weeks of silence followed by a tense one. Restate the amount and date you agreed on, the ones you have in writing. If the delay drags on, a courteous visit is often more effective than another round of messages. And if the amount at stake is significant and nothing works, keep every written record — it is your best protection if you need to pursue it further.

A job framed clearly from the start — a clear price, a reasonable deposit, a written note fixing expectations — almost always ends well, and a job that ends well leads to a good review. It is the same habit of clarity that protects you from non-payment and builds your reputation over time: see how to build a reputation from scratch.

Frequently asked questions

What deposit is reasonable?expand_more
Between 30 and 40 percent of the total is standard, with materials cost covered at minimum. Adjust for the size of the job and the trust already built with the customer.
What if the customer refuses to pay a deposit?expand_more
Explain that it protects both sides, not just you. If the refusal persists on a job with significant materials, it is better to nail the price down in writing before committing, or to decline the job.
Does a WhatsApp message count as proof of agreement?expand_more
Yes, in practice. A message summarising the price, what it covers and the deposit carries the same weight as a signed document in establishing what was agreed.
How do I chase a customer who is not paying?expand_more
Early and politely. A message the day after the agreed deadline, restating the written amount, works better than a long silence followed by a harsh tone.
Should I charge everything up front on a big job?
