Look official.
Get paid faster.
Branded, VAT-ready invoices, quotes and receipts — sent on WhatsApp, tracked to the dollar, ready for the GRA on the 21st. No accounting degree required.
No card required · Works on your phone · Made in Georgetown
Everything a Guyanese business needs to get paid.
Not another bloated accounting suite. Documents, balances and VAT — done properly, in the app you actually see below.
Invoices that look official
Tax invoices, quotes, receipts and credit notes with every field the GRA expects — serial numbers automatic, your brand on every sheet, five print templates to pick from.
Customers see exactly how to pay
Share any invoice by WhatsApp. The link opens a clean page with your bank and MMG details and an “I've paid” button — so the money comes back faster.
Know what's on the shelf — and what it earns
Count cases, packs and singles, log what moves, and see estimated profit and margin per item. Built for the mini-mart and hardware store, not the accountant.

“I'm a Queen's College alumnus and a law student, and I've loved business for as long as I can remember. For the better part of four years I've been building BillBook, because I'm convinced Guyanese businesses deserve tools as modern as anywhere in the world — VAT-ready, WhatsApp-native, and priced in dollars that make sense here. This is my shot at modernizing how we do business at home, one honest invoice at a time. If you send bills and want them taken seriously, I'd love for you to be one of the first.”

Everything
you're
wondering.
Straight answers — no fine print. Still stuck? A real person replies on WhatsApp, usually same-day.
Ask on WhatsAppWhat does 'VAT-ready' mean?+
Documents carry the fields GRA guidance expects — the 'Tax Invoice' heading, your TIN and VAT registration number, per-line VAT treatment (14%, zero-rated or exempt), unique serial numbers and issue dates. You stay responsible for your own filings; we make preparing them fast.
I'm not VAT-registered. Can I still use it?+
Yes. Set your business to non-VAT mode and your documents are issued without VAT. When you approach the G$15,000,000 registration threshold, you'll be ready to switch.
How does WhatsApp sending work?+
One tap opens WhatsApp on your phone with the message and document link prefilled — you press send. No new app for your customers to learn.
Does it work on my phone?+
BillBook is built phone-first. Everything — creating invoices, recording payments, sending documents — works from your browser on any smartphone.
What does it cost?+
Start free — 5 invoices and 5 quotes a month, forever. Paid plans (from G$4,000/mo) lift the limits and add stock, contracts, insights and more. Every new account also gets 14 days of the Growth plan free, no card needed.
Can I cancel anytime?+
Yes — no contracts, no cancellation fee. Moving down a plan or leaving is always free; you keep the plan you paid for until the month ends. Your data stays yours and you can export it all first.
What if I'm not tech-savvy?+
If you can send a WhatsApp, you can use BillBook. It's built to be simple, and there's a guided tour in the app plus a Help Center — and a real person on WhatsApp, usually same-day, if you get stuck.
Is my data safe?+
Yes. Everything runs over encrypted connections on a secured cloud database with automatic backups, rate-limiting and security headers in place. Your books are yours — export everything from Settings whenever you want.
Where is my data stored?+
In a secured cloud PostgreSQL database, backed up automatically. Your data belongs to you and can be exported from Settings at any time.
