What are the best payment terms for a contractor invoice?

For most residential trade work, "due on receipt" or "net 7" gets you paid fastest. For larger jobs, take a 30–50% deposit and bill the balance on completion. For commercial or repeat clients, net 15 to net 30 is normal. Always state a specific calendar due date rather than vague terms.

What does Net 30 mean on an invoice?

Net 30 means the full invoice amount is due 30 days from the invoice date. It is common in commercial work but means you wait a month to be paid, so build that delay into your cash flow and consider shorter terms or a deposit for residential clients.

Can a contractor charge a late fee on an unpaid invoice?

Yes, as long as the late fee is disclosed on the invoice or contract before the work and is reasonable — typically 1.5% per month (about 18% per year). Check your state limits, state the fee clearly on every invoice, and you do not have to enforce it every time for it to change client behaviour.

Contract Invoice Payment Terms for Trade Contractors

What each payment term actually means

Payment terms are the rules attached to an invoice that tell the client when and how to pay. They sound like accounting jargon, but for a trade contractor they directly control how fast cash lands in your account. Here is what the common ones actually mean.

Due on receipt — payment is expected as soon as the client gets the invoice. Best for residential jobs where you want to be paid the day the work is done.
Net 7 / Net 15 / Net 30 — payment is due 7, 15, or 30 days after the invoice date. "Net 30" is the most common in commercial work, but it is also where contractors wait longest for money.
50% deposit, balance on completion — half up front, half when the job is finished. Standard for larger jobs and a good way to cover your materials cost before you spend it.
Progress / milestone billing — you invoice in stages on a multi-day job (deposit, mid-point, final). Keeps cash flowing instead of waiting for one large payment at the end.
Late fee — a charge added when payment is overdue, usually expressed as 1.5% per month (about 18% annually). Make sure it appears on the invoice, not just in a contract the client never reads.

The mistake most contractors make is using vague terms. "Net 30" means different things to different clients, and "payment appreciated promptly" means nothing. Replace it with a concrete date: "Due by July 5, 2026." Specific dates get paid faster than open-ended terms, especially with residential clients who do not handle invoices regularly.

Which terms to use, by job type

There is no single right answer — the term should match the client and the size of the job.

Small residential jobs (under $1,500)

Use due on receipt or net 7. The client is a homeowner, the work is done, and there is no reason to wait. Send the invoice the moment you finish, include a payment link, and most will pay within a day or two.

Larger residential jobs (over $1,500)

Take a 30–50% deposit up front, then invoice the balance due on receipt at completion. The deposit covers your materials and filters out clients who were never serious. Clients who have hired contractors before expect this.

Commercial and repeat clients

Net 15 or net 30 is normal here because the client is running their own accounts-payable cycle. Build that delay into your pricing and cash-flow planning — a client who reliably pays in 30 days is effectively borrowing from you interest-free, which is fine if you priced for it.

Whatever you choose, the term should be on the invoice in plain language. For more on getting paid quickly once the invoice goes out, see How to Get Paid Faster as a Contractor.

Deposits, late fees, and making terms stick

Terms only work if they have consequences. Two clauses do most of the work.

Deposits protect you before the job. Asking for 30–50% on jobs over $1,500 is standard and professional. A client who pushes back hard on a reasonable deposit for a large job is telling you something worth listening to.

Late fees protect you after the job. A 1.5%-per-month late fee, stated clearly on the invoice, gives an overdue payment a real cost and gives you a reason to follow up that is not personal. You do not have to enforce it every time — but having it written down changes the conversation.

The final piece is consistency. Send invoices immediately, set a specific due date, and follow up on a schedule rather than when you happen to remember. Fieldpaid sends automatic reminders at day 7, 14, and 30 and cancels them the moment the invoice is paid, so your terms get enforced without you making an awkward call.
