A client going silent after receiving an invoice is frustrating but not uncommon. Here's how to handle it methodically.

1. Don't assume the worst immediately

Emails get missed, people go on leave, and invoices genuinely slip through busy inboxes. Start with a calm, low-pressure follow-up.

2. Try a different communication channel

If email goes unanswered, try a phone call, a different email contact at the company, or a message through whatever platform you originally communicated on.

3. Send a formal notice

If silence continues past a reasonable window, send a clear written notice restating the amount owed, the original due date, and a new deadline for response.

4. Reference your contract or agreement

If you have a signed agreement, remind the client of the terms it contains — this often prompts a response even from someone actively avoiding the conversation.

5. Consider a collections process for larger amounts

For significant unpaid amounts, a formal demand letter or small claims process may be appropriate, depending on your location and the sum involved.

6. Learn from the experience

Consider requiring deposits or shorter payment terms for future engagements with new or unproven clients to reduce this risk going forward.
