The 7 / 14 / 28-day chasers you keep forgetting to send.
You finished the job three weeks ago. The customer was lovely. The invoice is still unpaid. You hate chasing — it feels rude, even though it's their money you've already spent on materials — so you don't, and now you're £4k short for VAT.
Set the rhythm once — 7 days polite, 14 days firmer, 28 days final warning. Hint sends each chaser in your firm's tone of voice, automatically pauses if the customer replies or pays, and shows you who owes what in a single view. The VAT quarter stops being a panic.
Free to start. Open it and have a go — pay only when it's pulling its weight.
