Invoice [[invoice number]]: work paused until payment is received

Hi {{first_name}},

I understand that cash flow can be unpredictable. If paying Invoice [[invoice number]] ([[amount]]) in full right now isn't feasible, I'm open to discussing a payment schedule.

Could you let me know what timeline would work on your end? I'd rather find a solution that works for both of us than let this sit unresolved.

Hi {{first_name}},

This is a final notice regarding Invoice [[invoice number]] for [[amount]], now [[number]] days overdue. I've sent several reminders without a response.

If payment is not received by [[date]], I will need to [[specific consequence per your contract: apply the late fee outlined in our agreement, refer this account to collections, or engage a third party for resolution]].

I'd much rather resolve this directly. Please reply with a payment date or call me at [[your phone number]] to discuss.
