We turn your inbox into your collections team.
Paid finds every overdue invoice in your QuickBooks, drafts the follow-up in your voice, and queues it in your Gmail for one-click approval. Nothing sends without you.

Why this is broken for A/E firms
You designed the building. You shouldn't have to chase the check.

overdue invoices never get a single follow-up email
How it works
You stay in Gmail. We do the chasing.
Connect QuickBooks
We pull every open invoice, the work it covers, and how long it has been overdue.
We draft the follow-up
Tone calibrated by client history and invoice size. Pay Now button included. Sounds like you wrote it.
You approve in Gmail
One click sends from your real address. Nothing goes out without your approval.
Built for firms that bill on trust — and need the cash in the door.
What you get
01Reminders go out from your real Gmail — never from a noreply address
02Tone slides from friendly to firm based on client history and invoice size
03Pay Now button on every email, with optional early-pay discount or payment plan
04Replies are read and classified — “will pay next week” schedules a follow-up automatically
05Send the whole queue to your bookkeeper with one share link
What we hear from owners
The pattern is always the same.
Paraphrased from conversations with A/E firm partners and managing principals during early access.
“
I have a folder of invoices my clients should have paid eight weeks ago. I just never get around to writing the email. By the time I do, I feel weird about it.
Principal, Civil Engineering Firm
“
Two of my partners do the technical work. The third partner does the reminders, on Fridays, when they remember. It is the worst use of partner time we have.

Our average is 80-something days to get paid. Half the clients pay within a week if I just ask. I never ask.
