Question 1

What does it cost to automate invoice chasing in the UK?

Accepted Answer

7 days free, then £19 a month for the whole company. A card is taken today and you are charged £19 on day 8 unless you cancel. Cancel any time. The first 50 companies pay £19; after that it is £49 a month.

Question 2

What is the £950 deposit?

Accepted Answer

Build Your Own is a £950 deposit. We audit, build and test. If you want it running after that, monthly at an amount we agree from the scope.

Question 3

Can AI chase invoices without sending anything wrong?

Accepted Answer

The fear is that something goes to a customer in your name that you would never have written. Nothing goes out to your customer without your tap. Overnight Harness works out who has not paid. Your connected ChatGPT or Claude writes the chase, you read it on your phone, and you approve, edit or skip each one. The approval gate covers sends and is enforced, not left as a setting. Every draft, edit, approval and send is logged.

Question 4

Do I need new software?

Accepted Answer

You already pay for tools you barely use, so another login is the last thing you want. There is no new system to learn. It runs on the ChatGPT or Claude account you already have and works with what you use today. Your accounting and your inbox stay exactly where they are.

Question 5

How long does setup take?

Accepted Answer

You want to know how long the disruption lasts. Setup is designed to be short, and we tell you the current connection steps before you pay anything.

Question 6

We already use ChatGPT. Is this not the same thing?

Accepted Answer

It is ChatGPT with the steps you never get round to. The work is not the writing, it is remembering who went quiet three weeks ago while you were on a job, checking it against what has been paid, and having the chase drafted before you wake up.

Question 7

Is my data safe?

Accepted Answer

You are handing over the details of who owes you money, so the question is fair. Your books and your email stay where they are. What we hold is the chase list and the logins you connect, encrypted, on our UK servers. Your card goes to Stripe, never to us. You connect through each tool's own login screen, so we never see a password. You can pull the access any time, and you can sack us any month. No lock-in, on purpose.

Question 8

Who is this not for?

Accepted Answer

Not for people who do not use AI yet. Not for anyone who wants every email going out unsupervised from day one: Harness asks every time, and only the gentle reminders can ever earn the right to stop asking. Not for anyone who wants their core systems ripped out. We work with what you have.
