Overdue invoice reminder software for trade shops
You did the work. The invoice is out. Now you are the one chasing it, between jobs, after hours, on your own phone. PaidUp sends the follow-ups for you by email, so the money comes in without the awkward call.
The chasing stops being your second job
Most late payments are not a dispute. Somebody got busy, the invoice slipped down the inbox, and nobody reminded them. PaidUp keeps a polite, steady sequence going until the invoice is paid, and stops the moment you mark it paid. You stay on the job. The reminders go out on time, every time, in your business's name.
Friendly, firm, then final
Every overdue invoice follows the same three steps. First, a friendly reminder that the invoice is due. Then a firmer note when it is still unpaid. Then a final notice that makes clear you expect payment. You can preview each step before it sends, and you can see at a glance which invoices are 1 to 15 days overdue, 16 to 30, 31 to 60, or over 60 days. Nothing sits in a pile until it becomes a write-off.
Built for HVAC, plumbing, electrical, and contracting shops
PaidUp is not accounting software and it is not built for a finance team. It is built for a shop that invoices after the job is done: a repair, an install, a service call. Add invoices by hand or import them from a CSV, and PaidUp sorts them oldest first so the invoice that has waited longest is the one you deal with first. No QuickBooks subscription required. No per-user pricing. No setup call.

How it works
- Add your invoice: customer name, email, amount, and due date, or import a CSV.
- PaidUp watches the due date and sends the friendly, firm, then final reminders by email.
- You mark the invoice paid. The reminders stop.
That is the whole system. If you can send an email, you can run PaidUp.
