Invoice Payment Terms Explained: Net 30, Due on Receipt, Deposits and More

Two words at the bottom of your invoice decide when you actually get paid. "Net 30" means one thing to an accounts team and something fuzzier to a homeowner. "Due on receipt" sounds firm but is routinely ignored. The payment terms you choose, and how clearly you state them, quietly control your cash flow more than the size of the job does. Pick the wrong terms for the wrong client and you fund their project out of your own pocket for two months.

This is the reference for the terms themselves. We are not covering speed tactics here (that is our guide to getting paid faster) or the full anatomy of an invoice document. This article does one job: define the common payment terms, show what each does to your days-to-pay and cash flow with real numbers, and help you pick the right one for each job and each client.

What "payment terms" actually means

Payment terms are the agreement for when and how a client pays you. At a minimum that is a deadline: the date the money is due relative to the invoice date. Good terms also spell out what happens around that deadline: any deposit taken before work starts, a discount for paying early, a late fee if the deadline is missed, and the payment methods you accept.

Two numbers matter for your business. The first is days-to-pay: how many days pass between sending the invoice and the money landing. The second is cash-flow exposure: how much of your own money (labour already paid, materials already bought) is tied up while you wait. Every term below moves one or both of these. Your goal is to shorten days-to-pay and shrink exposure without scaring off good clients.

The common payment terms, defined

Due on receipt

What it means: payment is expected immediately, as soon as the client gets the invoice. There is no grace period.

When to use it in the trades: small one-off jobs and first-time residential clients. The homeowner whose tap you fixed in an hour, the emergency callout, the GBP 180 drain unblock. They are standing right there, the work is done, and there is no reason to wait. This is your default for cash-and-carry style work.

Cash-flow effect: the shortest possible exposure, in theory. In practice "due on receipt" is the term most often treated as "whenever I get round to it," because there is no concrete date to miss. It works best when you pair it with an on-the-spot payment method so the client can settle there and then, rather than promising to "do it later."

Net 7

What it means: payment is due 7 days after the invoice date. Send it on the 1st, it is due on the 8th.

When to use it: regular residential and small-commercial work where the client needs a few days to action a transfer but you do not want to carry the balance for weeks. A good middle ground for repeat customers who pay reliably but not instantly.

Cash-flow effect: tight and healthy. On a GBP 924 job, net 7 means your money is realistically back within 7 to 14 days even allowing for the typical slip. Compared with net 30, net 7 can pull two to three weeks of cash forward, which is the difference between buying the next job's materials with your own money or the last client's.

Net 14

What it means: due 14 days after the invoice date.

When to use it: the sensible default for most small-contractor invoices. It gives a business client time to run the invoice through their process without giving them an excuse to forget. For a lot of tradespeople, net 14 is the sweet spot: short enough to protect cash flow, long enough to feel reasonable to a paying client.

Cash-flow effect: moderate exposure. Expect real-world payment around day 14 to 28. If you have bought materials upfront, net 14 means you are out of pocket for roughly two to four weeks, which most jobs can absorb.

Net 30

What it means: due 30 days after the invoice date.

When to use it: larger commercial clients, builders, property managers, and main contractors who genuinely run on monthly payment cycles and will not accept anything shorter. If a client's accounts department processes payments once a month, net 30 simply matches their reality. Use it because the client requires it, not because it sounds professional.

Cash-flow effect: the heaviest exposure of the standard terms. The hard truth is that net 30 rarely means 30 days. Small-business invoices are commonly paid 14 to 30 days late on top of the stated term, so a net 30 invoice routinely settles in 44 to 60 days. On a GBP 6,000 job where you have already paid subcontractors and bought materials, that is two months of carrying thousands of pounds of someone else's project. Only offer net 30 when the job margin and your reserves can take the wait, and protect it with a deposit (below).

50% upfront, balance on completion

What it means: the client pays half before you start and the rest when the job is finished. The split can be 30/70, 40/60, or 50/50 depending on how much material you have to front.

When to use it: larger jobs where you buy materials before you earn anything: a kitchen fit-out, a re-roof, a full repaint, a patio. The upfront portion covers your materials and protects you if the client vanishes. It is also a useful filter: a serious client pays a reasonable deposit without fuss.

Cash-flow effect: this is the single biggest improvement you can make to exposure on big jobs. On a GBP 4,000 job with GBP 1,500 of materials, taking GBP 2,000 upfront means you never go negative on the project. Without it, you are GBP 1,500 down on day one and stay there until the final payment clears.

How this works with Billr: Billr does not automate deposits or split a single invoice into instalments. In practice you arrange the upfront amount with the client directly, then send a Billr invoice for the deposit with the due date set to before the start date, and a second invoice for the balance when the job is done. Each invoice carries its own pay link and is tracked separately, so you can see exactly which half is paid.

Stage or milestone payments

What it means: the total is split into agreed chunks tied to progress, for example 25% on signing, 25% at first fix, 25% at second fix, 25% on completion. Each milestone is invoiced as it is reached.

When to use it: long-running projects measured in weeks or months: extensions, full renovations, large landscaping or fit-out jobs. Milestone billing keeps cash flowing in throughout the project instead of you waiting until the very end to see any money, and it limits how much you are ever owed at once.

Cash-flow effect: the lowest sustained exposure for big work, because you are never carrying the whole project. The trade-off is admin: you have to invoice at each stage and keep track of what has been billed.

How this works with Billr: there is no automatic staged-payment schedule in Billr. You bill milestones manually by sending a separate invoice at each stage, each with its own due date and pay link. Because every invoice shows a clear status, your dashboard balance tells you at a glance how much of the project is still outstanding.

2/10 net 30 (early-payment discount)

What it means: the client may take a 2% discount if they pay within 10 days; otherwise the full amount is due in 30. The notation is read as "two ten, net thirty."

When to use it: when you deal with slower-paying commercial clients on net 30 and you would rather have the cash now than the last 2%. It gives the client a concrete reason to jump the queue and pay you ahead of their other suppliers.

Cash-flow effect: you give up a small slice of revenue to pull payment forward by roughly 20 to 50 days. On a GBP 3,000 invoice, a 2% discount is GBP 60. If that turns a 50-day wait into a 10-day one, you have effectively bought 40 days of cash for GBP 60. Whether that is worth it depends on how badly you need the money sooner. Many tradespeople find a flat early-pay sweetener works just as well and is easier to explain than the formula.

Terms at a glance

• Due on receipt: tiny jobs, first-timers, callouts. Shortest exposure if paid on the spot; vaguest deadline if not.
• Net 7: reliable repeat residential. Tight, healthy cash flow.
• Net 14: the all-round default for small contractors. Reasonable to clients, kind to your cash.
• Net 30: commercial clients and main contractors who require it. Heaviest exposure; protect with a deposit.
• 50% upfront: material-heavy jobs. Removes most of your exposure on big work.
• Milestone payments: long projects. Steady cash in, lowest sustained exposure, more admin.
• 2/10 net 30: slow commercial payers. Trade a small discount for much faster cash.

Which terms to pick for which job and client

Terms are not one-size-fits-all. Match them to two things: the size of the job and how well you know the client.

• Small job, new residential client: due on receipt, ideally paid on the spot. There is no reason to extend credit to someone you have never billed before.
• Small job, trusted repeat client: net 7 or net 14. Reward reliability with a little breathing room, but keep it short.
• Medium job with materials: a deposit (30 to 50%) plus net 14 on the balance. The deposit covers your outlay; the short balance term keeps the tail tight.
• Large job, weeks or months long: milestone payments. Never let the amount you are owed grow to the full project value.
• Commercial client or main contractor: match their cycle (often net 30), but take a deposit on anything sizeable and consider an early-payment discount to pull cash forward.

One rule cuts across all of these: the bigger your upfront outlay, the more you protect yourself with a deposit, and the shorter you keep the term on the balance.

How to state your terms so they actually get honoured

The clearest term in the world does nothing if the client only sees it after the work is done. Two things make terms stick.

Agree them upfront, in writing

State your terms before you start the job, not on the final invoice. A line in your quote, your booking confirmation, or a text message ("GBP 2,000 deposit to book, balance due within 14 days of completion") means the invoice is just a reminder of something already agreed, not a surprise. Surprises are what get disputed.

Put a real date on the invoice, not just a label

"Net 14" forces the client to do the maths and gives them room to forget. "Payment due by 2 July 2026" is a deadline, and deadlines get met. Always convert your term into an actual calendar due date on the document. In Billr, every invoice carries a due date (it defaults to roughly +15 days, and you can set it per invoice), and that date is printed clearly on the invoice the client sees. Because the invoice can also carry a card, PayPal, bank-transfer, or QR pay link, a short term like net 7 is realistic: the client can pay the moment they open it. Once they do through Stripe or PayPal, Billr marks the invoice paid automatically, so your records never drift. See how the invoicing and payment features fit together.

Early-payment discounts and late fees

Two levers sit on either side of your due date. Use them deliberately.

Early-payment discounts pull cash forward by giving the client a reason to pay now. A simple "2% off if paid within 7 days" or a flat "GBP 25 off for payment within a week" can be more effective than the formal 2/10 net 30 notation, because tradespeople's clients understand a plain offer faster. Only offer a discount you can afford to give up; it comes straight out of your margin.

Late fees protect the back end. A clearly stated late fee ("a 5% charge applies to balances unpaid after the due date") signals that the deadline is real. The key word is stated: a fee you spring on a client after the fact will be argued; a fee they agreed to upfront usually gets the invoice paid before it ever applies. Check what your local law allows before setting a rate. The fee is less about the money and more about making your deadline matter.

Key takeaways

• Payment terms control two things: how fast you get paid (days-to-pay) and how much of your own money is tied up while you wait (cash-flow exposure).
• Net 14 is the sensible default for most small-contractor work. Use net 7 for trusted repeat clients and reserve net 30 for commercial clients who genuinely require it.
• On material-heavy jobs, a 30 to 50% deposit removes most of your exposure. On long projects, milestone payments keep cash coming in throughout.
• Billr does not automate deposits, instalments, recurring invoices, or staged-payment schedules. You arrange the upfront amount yourself and send a separate invoice per stage, each with its own due date and pay link.
• Agree terms upfront in writing and print a real calendar due date on the invoice, not just a label. Pair short terms with an online pay link so paying on time is the easy option.

Frequently asked questions

What is the most common payment term for tradespeople?

Net 14 and net 30 are the most common, but the right one depends on the client. Residential one-off work is usually due on receipt or net 7; commercial clients and main contractors typically expect net 30. For most small contractors, net 14 is a strong default for invoiced work.

Does "due on receipt" mean the client has to pay immediately?

That is the intent: payment is expected as soon as the invoice arrives, with no grace period. In practice, without a concrete due date people treat it loosely. It works best for small jobs paid on the spot, ideally with an online pay link so the client can settle there and then.

Can Billr take a deposit or split an invoice into instalments?

No. Billr does not automate deposits, partial pre-payments, instalments, or staged-payment schedules, and it does not create recurring invoices or send automatic reminders. To take an upfront amount you arrange it with the client and send a Billr invoice for the deposit, then a second invoice for the balance. Each invoice has its own due date and pay link and is tracked separately.

Should I charge a late fee?

A clearly stated late fee makes your deadline feel real, and it usually works by deterrence rather than ever being charged. State it upfront in your quote and on the invoice, keep it reasonable, and check what your local law permits before setting a rate.

Are early-payment discounts worth it?

They can be, if you genuinely need cash sooner. Giving up 2% to turn a 50-day wait into a 10-day one is buying time with margin. If your cash flow is comfortable, you are better off keeping the full amount and simply using short terms with an easy online payment option.

Clear payment terms plus a due date the client cannot miss are the simplest way to get paid on time. Billr puts a real due date and an online pay link on every invoice, so the easy path for your client is also the fast one for you. See Billr's plans and start getting paid on your terms.
