What to do when a client refuses to pay before you sue them

You did the work. You sent the invoice. And now it's been 45 days and nothing.

Before you call an attorney, there are a few things worth trying. Not because litigation is a last resort — sometimes it isn't — but because most payment disputes resolve before they get that far, and how you handle the early stages affects your options later.

Here's what that looks like in practice.

Start with a direct conversation, not a formal notice.

This sounds obvious. Most people skip it. They send an email instead of calling, or they wait hoping the invoice will get paid, or they escalate immediately because they're frustrated.

A direct phone call — not a demand letter, not a collections notice — resolves more payment disputes than anything else. People pay invoices they forgot about. They explain a cash flow problem you didn't know they had. They give you information that changes your options.

Make the call. Document that you made it.

Send a clear written follow-up.

If the call doesn't resolve it, follow up in writing within 48 hours. Not a legal threat — a clear, professional summary of what's owed, when it was due, and what you need to resolve it.

Keep it short. Keep it factual. Avoid language that sounds angry or accusatory even if you are.

This email matters later. If the dispute escalates, it becomes part of your documentation.

What to include:

• The invoice number and original due date

• The amount outstanding

• A specific new deadline — "by [date]" not "as soon as possible"

• Your preferred payment method

• A single sentence offering to discuss if there's an issue

Understand what kind of dispute you're actually dealing with.

Most unpaid invoices fall into one of three categories, and each one has a different approach.

They forgot or deprioritized it.
The most common situation. A direct conversation and a clear follow-up resolves this most of the time.

They're disputing the work.
They're claiming something wasn't delivered, or the quality was below what was agreed. This is a contract dispute, not just a collections issue. You need to understand what they're actually claiming before you respond.

They're stalling because of cash flow.
They intend to pay but can't right now. A payment plan negotiated early is almost always better than a dispute that drags out for months.

Knowing which one you're dealing with tells you what your next step actually is.
