Payment terms are one of those things freelancers often skip over, either because they feel awkward talking about money upfront, or because they assume clients already know the deal.

They don't. And that assumption is why so many invoices end up paid late.

What are payment terms?

Payment terms define when and how you expect to be paid. The most common ones you'll see:

Net 7: payment due within 7 days
Net 14: payment due within 14 days
Net 30: payment due within 30 days
Due on receipt: payment expected immediately

Most freelancers default to Net 30 because it's industry standard. But for small projects and solo clients, Net 14 or even Net 7 is completely reasonable, and worth asking for.

Where to include your payment terms

Payment terms should appear in three places:

1. Your contract

This is the most important. Before any project starts, your contract should specify:

Payment schedule (e.g. 50% upfront, 50% on delivery)
Due dates relative to invoice date
Late payment policy (more on this below)
Accepted payment methods

If you don't have a contract, start here first.

2. Your invoice

Every invoice you send should clearly state the due date. Not "Net 30", the actual date. Clients shouldn't have to calculate it.

Good: "Payment due: 14 March 2026" Less good: "Payment terms: Net 30"

3. Your follow-up emails

When you send an invoice, include a one-liner mentioning the due date. When you follow up, reference it again. Repetition isn't nagging. It's professional clarity.

Late payment fees: do they work?

Some freelancers add a late payment clause, typically 1.5–2% per month on overdue balances. In theory, this incentivises timely payment. In practice, it depends on your relationship with the client.

For large corporate clients, it's worth including. They're used to it. For small businesses or individuals, it can sometimes feel adversarial.

A lighter alternative: mention that invoices overdue by 30+ days may be subject to a late fee, without specifying the amount. This signals you're serious without being aggressive.

The upfront deposit model

One of the most effective ways to protect yourself as a freelancer is to require a deposit before starting work. Common structures:

50% upfront, 50% on delivery: standard for project work
33% at start, 33% at midpoint, 33% on delivery: good for longer projects
100% upfront: works for smaller or first-time clients

Getting paid upfront changes the dynamic entirely. You're no longer chasing money you've already earned. You're finishing the work before releasing the final payment.

What to do when terms are ignored

Even with clear terms, some clients pay late. Here's a simple escalation path:

Day 1 overdue: Friendly reminder, assume it was an oversight
Day 7 overdue: Follow up with reference to your payment terms
Day 14 overdue: Ask for a payment date commitment
Day 30+ overdue: Formal notice referencing late fees; consider pausing future work

Most invoices get paid by step 2. The key is consistency: following up every time, not just when it feels convenient.

Automate the process

The friction isn't usually in knowing what to do. It's in actually doing it, every time, for every client. Writing reminder emails takes mental energy that most freelancers don't want to spend.

Setting up automated reminders means your payment terms are enforced consistently, without you having to think about it. Nüdge Theory lets you configure exactly when reminders go out, before and after the due date, and handles the follow-ups for you.
