Client never received the invoice? What to do

“Oh? I never received your invoice.” It’s one of the most common lines you hear when chasing payment. Sometimes it’s true (the email went to spam), but more often it’s a convenient excuse to stall. The key is to neither break the relationship nor let it become an open-ended shield for delay.

First: genuine, or an excuse?

If the client never responded to any earlier reminder and suddenly says “didn’t get it”, credibility is low.
If you can see the email was delivered or even opened, it’s most likely an excuse.

Standard response: remove the excuse on the spot

Whether genuine or not, the smartest reply is to kill the excuse immediately:

“Sorry for the inconvenience! I’m resending it now. Invoice INV-XXX, amount $X,X00, originally due [date]. Could you confirm once it arrives and let me know the expected payment date? Thanks!”

This reply does three things: resends (removing the excuse), restates the key facts (locking them in), and asks for a specific payment date (putting the ball back in their court).

Remove it at the source

Make “I didn’t get it” impossible to stand on:

Send with a trail: use a method where you can see delivery / open status.
Clear invoice numbers: a unique number per invoice for easy reconciliation (see invoice numbering best practices).
Put key info in the body: not just the attachment — write the invoice number, amount and due date in the email body too.
Reconcile regularly: send a monthly statement of account, where every unpaid invoice is visible and “didn’t get it” has nowhere to hide.

Let the system keep watch

Remembering “who to resend to, who hasn’t paid” by hand is tiring. Duefy tracks each invoice’s send and payment status and follows up automatically — however many excuses there are, they can’t get around reminders that arrive on time.
