The website that sells BillBook — with Tristan, an AI helper, on the page
The public face of BillBook. It has to explain VAT software to a shop owner in one scroll, answer the price question up front, and get them signed up in under two minutes — with an AI helper answering questions along the way.
What we built
- Pricing in Guyana dollars, with a free plan up front
- Pages for contractors, mini-marts, restaurants, trucking and salons
- A free import-duty calculator, its vehicle maths checked against GRA's own examples
- Tristan, an AI helper that answers questions on the page
The standout
Tristan answers the moment they ask
An AI helper on the page answers questions in plain English — prices, VAT, how getting paid works — with plan prices fed straight from the live price list. When someone's ready, it points them to the free plan.

The breakdown
Everything it does, front to back.
8 things this site handles — most of them invisible until you need them.
What visitors see
One-scroll explanation
What BillBook does, who it's for and what it costs — before anyone has to ask.
A page per industry
Contractors, mini-marts, restaurants, trucking and salons each get their own page.
Pricing in G$
A free plan, then G$4,000, G$5,500 and G$18,000 a month, with a 21-day free trial of Growth.
Free import-duty calculator
Duty on vehicles and everyday goods, with the vehicle maths checked against GRA's own worked examples.
A help centre
Plain-English guides on VAT, documents, sharing, payments and stock.
What runs behind it
The AI stays on the server
Tristan talks to the AI through BillBook's own server, so the account key never reaches the browser.
Guard rails
Rate-limited per visitor, a short memory and plain-text answers. It says it's AI when asked, and it's told to quote only the real price list, with no made-up discounts or dates.
One price list for site and app
Plan prices come from the same list the app bills from, so a price change shows up on the site and in the app together.
