Checked against GRA guidance. GRA does not certify software — anyone saying “GRA-approved” is guessing. Cash sales of G$10,000 or less switch to a sales invoice automatically. Read the VAT guide →

“I've spent four years building BillBook because Guyanese businesses deserve tools as modern as anywhere in the world — VAT-ready, WhatsApp-native, priced in dollars that make sense here. If you send bills and want them taken seriously, I'd love for you to be one of the first.”

Your books stay yours.
Encrypted in transit and at rest, backed up daily, exportable from Settings any time. Built with Guyana's Data Protection Act 2023 in mind. We never see your MMG PIN.
How we handle data →Straight answers.
No fine print. Still stuck? A real person replies on WhatsApp, usually the same day.
What 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.
Can I take MMG on every invoice?
Yes. Your MMG and bank details print on every document and on the pay page your customer opens from WhatsApp. They pay, tap “I've paid”, you record it and the receipt goes back to them.
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. Add it to your home screen and it opens like an app.
What does it cost?
Start free: 5 quotes or invoices and 10 receipts a month, forever. Paid plans from G$4,000 a month, in Guyana dollars, paid by MMG or bank transfer. Every account also gets 14 days of the Growth plan free — the clock starts at your first document, not at signup, so none of it goes to waste. No card needed.
My accountant works in QuickBooks, Sage or Excel. Will this fit?
Yes. Hand them the month in one go: output-VAT summary, customer statements, aging and CSV exports, ready before the 21st. BillBook runs the paperwork; they keep the books however they like.
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? Where is it stored?
Yes. Everything runs over encrypted connections on a secured cloud PostgreSQL database with automatic backups, rate-limiting and security headers in place. Your books are yours — export everything from Settings whenever you want.
