Ask me anything before you pay

Start with the 30-second fit check. Harness itself is £19 a month for the whole company, with the first 7 days free. A card is taken today and you are charged £19 on day 8 unless you cancel. Cancel any time. Custom workflow builds are £250 each, one-off, and the first three are free with an install. 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. If you would rather see it first, book twenty minutes.

Getting Harness going is a login. You add it as a connector in ChatGPT or Claude, sign in once, and connect your own tools from the chat. There is no terminal, no code and nothing to install. Custom workflows on top of that are usually built within the week, and if yours will take longer you hear that first.

Harness is built for UK businesses. It reads UK accounting software, writes in British English and works to UK payment terms, so that is where it is any good. If you are outside the UK and want to try it anyway, email me first and I will tell you honestly whether it will do anything useful for you.

You email or ring me and I fix it. There is no support tier to buy and no ticket queue to sit in. If a chase goes wrong you can see exactly what was drafted, what you approved and what was sent, because all of it is logged.
