When you send an invoice, the payment terms you choose do more than set a deadline. They signal how you run your business, shape your cash flow, and — if you pick the wrong ones — can slow down payment without you realising it.
Here's what the most common invoice payment terms actually mean, and how to decide which ones to use.
What Are Invoice Payment Terms?
Payment terms are the conditions under which you expect to be paid. They appear on an invoice and tell the client:
- When payment is due
- Whether any discounts apply for paying early
- Whether there are penalties for paying late
Most freelancers and small businesses use one of four standard terms. The rest of this guide breaks each one down.
Net 30
Meaning: Payment is due 30 days from the invoice date.
Net 30 is the most widely used payment term in business. It became the default because it gives buyers time to process invoices through their accounts payable system — useful for large companies with formal approval chains.
When it makes sense: When working with larger companies or agencies that genuinely need internal processing time. Corporate clients often expect Net 30 and will flag anything shorter.
When it works against you: For freelancers and small service businesses, Net 30 is often too generous. If you send an invoice on April 1, you don't get paid until May 1. Multiply that across several clients and your cash flow gets stretched.
The hidden problem: Many clients treat Net 30 as a floor, not a ceiling. They pay on day 30 (or day 35). If you need money sooner, don't start with terms that give them a 30-day window.
Net 15
Meaning: Payment is due 15 days from the invoice date.
Net 15 is the sweet spot for most freelancers and small businesses. It's short enough to maintain cash flow, but long enough that clients don't find it unreasonable.
When it makes sense: Service providers, consultants, designers, writers, developers — anyone who completes work and invoices immediately. If the deliverable is done and handed over, there's no reason the client needs 30 days to pay.
When to avoid it: If you're regularly working with large enterprise clients who can't route invoices quickly, Net 15 can create friction. Know your client before you set your terms.
Net 7
Meaning: Payment is due 7 days from the invoice date.
Net 7 is common for very small projects, one-off work, or clients you have an established relationship with. It's also standard in some industries — event work, short-term contracts, small trades jobs.
When it makes sense: Low-value invoices, trusted repeat clients, or situations where the payment process is simple (e.g. paying by card).
When to avoid it: New clients, large projects, or any client that works through a formal accounts payable process. Seven days is too tight for a corporate procurement chain.
Due on Receipt
Meaning: Payment is due immediately upon receiving the invoice.
Despite sounding aggressive, Due on Receipt is common and widely accepted — especially for client-facing service businesses, retail, events, and situations where payment follows delivery closely.
When it makes sense: When you hand over work and invoice at the same time. A photographer delivering a final gallery, a consultant wrapping up a one-day workshop, a developer pushing a small feature — these are natural moments for immediate invoicing.
When to avoid it: Project-based work where the client needs time to review before paying. Asking for payment on receipt before the client has had a chance to check the deliverables can create friction and disputes.
2/10 Net 30
Meaning: The client gets a 2% discount if they pay within 10 days; otherwise the full amount is due in 30 days.
This is an early-payment discount. It's a common tool in trade credit and B2B supply chains, less common for freelancers.
When it makes sense: If cash flow is tight and you'd genuinely rather receive 98% of an invoice in 10 days than 100% in 30, this term works. It's also a useful tool when you have clients who are reliable but slow.
When to avoid it: If your margins are thin, giving away 2% hurts. And most small-project clients won't take the time to do the maths — the discount may go unnoticed.
Late Payment Clauses
Payment terms can also include a late fee — typically something like 1.5% per month on balances outstanding past the due date, or a flat fee such as £25 after 14 days overdue.
A late payment clause doesn't just give you a mechanism to recover money. More importantly, it signals that you track due dates and take them seriously. That alone tends to move invoices up the priority list.
Keep the language simple and state it clearly near the bottom of the invoice.
How to Choose the Right Payment Terms
A few questions to work through:
What's your cash position? If you're waiting on several invoices at once, shorter terms protect you. If you can afford to wait, you have more flexibility.
Who is the client? A large company with a procurement team needs more time than a small business owner who pays from a single account. Match terms to the client's reality.
What's the project size? Small invoices can carry tighter terms than large ones. A £200 invoice with Net 7 is normal. A £15,000 project milestone with Net 7 may create friction.
What's standard in your industry? Advertising agencies expect Net 30. Event vendors expect payment on the day. Knowing your sector's norms helps you avoid unnecessary pushback.
Do you have an ongoing relationship? Long-term clients earn more flexibility. New clients start with whatever terms protect you.
A Note on Consistency
Whatever terms you choose, apply them consistently. An invoice that says Net 30 but is followed by a chasing email on day 20 confuses clients and undermines your own terms.
Set your terms, state them clearly, and then hold to them. If a client consistently pays late, address the terms in the next contract — not by chasing earlier each time.
Putting It on the Invoice
Payment terms should appear in two places:
- In the invoice header or summary block — alongside the due date. Don't just write "Net 30". Write "Net 30 — due 8 May 2026". The calculated date removes ambiguity.
- In the invoice footer — where you can also include your accepted payment methods and any late payment clause.
Plain Statement lets you set payment terms and due dates on every invoice, with the calculated due date displayed prominently so clients always know exactly when payment is expected.
