Offering a payment plan

Understanding & practicalAny stage (client in difficulty)
Subject line

Re: Invoice [#INVOICE]: payment plan option

Email body
Hi [CLIENT NAME],

I understand that cash flow can be unpredictable, and I appreciate you being upfront about the situation with invoice [#INVOICE] for [AMOUNT].

Rather than let this become a bigger issue, I'd like to offer a payment plan so we can resolve it in a way that works for both of us.

Here's what I'm proposing:
- [NUMBER] monthly payments of [INSTALLMENT AMOUNT]
- First payment due by [DATE]
- Remaining payments on the [DAY] of each following month

This keeps our working relationship intact and gives you a manageable path to settling the balance.

If this works for you, reply to confirm and I'll send a brief payment agreement for us both to sign. If you'd like to suggest different terms, I'm open to discussing.

Thanks,
[YOUR NAME]

Why invoices go unpaid

Before you assume the worst, understand that most unpaid invoices are not malicious. Knowing the reason helps you choose the right template and tone.

1

They simply forgot

The most common reason. Your invoice arrived during a busy week, got buried in email, and your client genuinely lost track of it. A polite nudge (template #1) solves this 80% of the time.

2

Cash flow problems

Your client wants to pay but does not have the funds right now. This is especially common with small businesses and startups. Offering a payment plan (template #7) preserves the relationship.

3

Disputed work or amount

The client has an issue with the deliverables, scope, or pricing but has not told you. The empathetic check-in (template #3) opens the door for this conversation.

4

Lost or misdirected invoice

The invoice went to the wrong email, got caught in spam, or was sent to an employee who left. Confirming receipt (template #1) catches this early.

5

Intentional non-payment

The least common but most frustrating reason. The client has no intention of paying. This is where escalation templates #5 and #6 exist, and why maintaining a paper trail from day one matters.

Step-by-step action plan for unpaid invoices

Follow this escalation timeline to maximize your chances of getting paid while keeping the relationship professional.
