How much deposit should you pay a contractor?

A contractor may ask for money before work begins for perfectly legitimate reasons.

Materials may need to be ordered, equipment booked or time reserved.

But there isn't one deposit percentage that automatically makes an arrangement reasonable or unreasonable.

Before paying, understand why the money is needed, what it covers, when future payments become due and what your written agreement says.

Why contractors ask for deposits

Depending on the job, an upfront payment may help cover things such as:

• materials;
• specially ordered items;
• equipment;
• supplier commitments;
• preliminary work; or
• reserving capacity for the project.

Not every contractor or project uses the same payment structure.

A small repair, custom installation and major renovation can have very different upfront costs.

Ask what the requested deposit is intended to cover rather than assuming every deposit serves the same purpose.

Is there a standard deposit percentage?

There isn't one universal percentage that is automatically appropriate for every contractor or project.

The amount can depend on:

• the total project value;
• materials required upfront;
• whether materials are standard or custom-made;
• supplier payment requirements;
• the length of the project;
• how the work is staged;
• the type of service; and
• the agreed contract terms.

Instead of asking only “What percentage is it?”, also ask:

“What does this amount pay for?”

Understand what the deposit covers

Before paying, ask for enough information to understand the request.

Depending on the project, useful questions include:

• What is the total quoted or estimated price?
• How much is required upfront?
• What does that payment cover?
• Are particular materials being ordered?
• Who will own materials once they're paid for?
• Are any items custom-made or non-returnable?
• When is the next payment due?
• What happens if the scope changes?
• What are the applicable cancellation terms?

The appropriate level of detail will depend on the size and complexity of the job.

Get the payment terms in writing

For substantial work, the quote, agreement or other appropriate written record should make the payment arrangement clear.

Depending on the job, record:

• total price or how the price will be calculated;
• deposit amount;
• what the deposit relates to;
• payment stages;
• due dates or milestones;
• materials;
• exclusions;
• how additional work is approved;
• cancellation terms; and
• any other agreed payment conditions.

Written terms don't guarantee that a project will go perfectly.

They give both sides a clearer record of what was agreed.

Consider staged or milestone payments

Larger projects may use payments linked to stages or milestones rather than one upfront amount and one final amount.

For example, a project might have payments associated with:

• ordering agreed materials;
• completion of a defined stage;
• installation of specified items; or
• another clearly described milestone.

There isn't one universal milestone schedule.

The stages should make sense for the particular project and be clear in the agreement.

Understand what triggers the next payment

Before work begins, establish what needs to happen before another payment becomes due.

A milestone should be described clearly enough that both customer and contractor understand it.

If a project changes, confirm how that affects the price and payment schedule before additional work proceeds where practical.

What about paying for materials upfront?

Material-heavy projects may require significant spending before installation begins.

If a large part of the deposit is for materials, consider asking:

• what is being purchased;
• approximately what it costs;
• whether it is standard or custom;
• when it is expected;
• where it will be delivered or stored; and
• what happens to the materials if the project is cancelled.

The answers will depend on the supplier and contract.

Don't assume that paying for materials automatically gives the customer legal ownership in every situation.

Is full payment upfront always a scam?

No.

Full upfront payment isn't automatically fraudulent.

Different services and products use different payment models.

But for substantial contracting work that will take place over time, it is reasonable to understand why the entire amount is being requested before work starts and what protection the written arrangement provides.

Treat an unusual or unexplained payment arrangement as a reason to ask more questions before paying.

Is paying cash a warning sign?

Cash itself doesn't prove anything is wrong.

Whatever payment method you use, keep an appropriate record of:

• how much you paid;
• when you paid;
• who received it; and
• what the payment was for.

If paying cash, ask for an appropriate receipt or acknowledgement.

Electronic payment isn't automatically safe either.

Payment fraud can happen through bank transfers and other payment methods.

Verify unexpected banking-detail changes

If a contractor's banking details unexpectedly change, pause before paying.

Confirm the new details directly with the contractor using a contact method you already know and trust.

Don't rely only on the message, email or invoice that supplied the changed details.

Where appropriate, check the account-holder information presented during your banking process as an additional piece of information.

A familiar-looking invoice or message doesn't by itself prove that payment details are genuine.

What if the price changes during the job?

Projects can uncover additional work or change after they begin.

A price change isn't automatically evidence of dishonesty.

Before additional work proceeds where practical, clarify:

• what changed;
• why it changed;
• the additional cost;
• whether materials are affected;
• whether timing changes; and
• how the payment schedule will be adjusted.

Keep agreed variations or change orders in an appropriate written form for substantial projects.

Keep your payment records

Keep relevant:

• quotes;
• contracts or agreements;
• invoices;
• receipts;
• proof of payment;
• material information;
• approved changes;
• messages; and
• completion or compliance documents where applicable.

These records don't prevent disputes, but they can help establish what was agreed and paid.

Where ID Verified fits

On Know a Pro, South African Pros complete identity verification as part of signup before their profile can go live.

Once completed, their profile can display the ID Verified badge.

ID Verified means the Pro completed Know a Pro's required identity-verification process.

It does not mean:

• a deposit request has been approved by Know a Pro;
• the amount is reasonable;
• banking details are genuine;
• the contractor will complete the job;
• the money can be recovered;
• the contractor is financially sound; or
• the transaction is risk-free.

Evaluate the payment arrangement separately.

Reviews don't make a deposit safe

Reviews can provide useful context about previous customer experiences.

They don't prove that:

• a current invoice is genuine;
• banking details are correct;
• a deposit is appropriate;
• the contractor will perform as expected; or
• your money is protected.

Read reviews as one part of the overall picture.

Questions to ask before paying

Before sending a contractor deposit, consider:

• What is the total project price or estimate?
• How much am I being asked to pay now?
• What does this payment cover?
• Are materials being purchased?
• What written record do I have?
• When is the next payment due?
• What milestone or event triggers it?
• How will extra work be approved?
• What happens if the project is cancelled?
• Have the banking details changed unexpectedly?
• Do I understand who I'm paying?

The bottom line

There is no single deposit percentage that tells you whether a contractor arrangement is good or bad.

Look at the amount in the context of the job.

Understand what the money covers, put important payment terms in writing, keep records, verify unexpected payment changes and make sure later payments are tied to terms you understand.

A deposit can be a normal part of contracting work without being something you should pay without asking questions.
