Why these exist
We build FlareApps for small Thai businesses. These are the pieces we pulled out so anyone can use them — no account, no waiting.

The technical set — JSON, Base64, hashes, QR codes, short links.
Open the ToolkitFrequently asked questions
- Do I need an account?
- No. Every tool on this page works straight away. The one thing an account adds is keeping your shopping note in your notebook.
- Do the numbers I type go anywhere?
- No. Every calculation happens in your browser. The page loads the published tax rates once when it opens, and after that nothing is sent.
- What is FlareApps?
- A business system for small Thai companies — menu, orders, stock, books and a shop website in one account. These free tools are pieces of it.
Want these numbers to come from your own shop?
FlareApps works with your business's own numbers — a plate cost from the recipe you recorded, VAT separated if your shop is VAT-registered, and withholding tax when you record a supplier payment.
FlareApps has a free plan you can start on today; paid business plans are billed monthly or yearly, per business. Every real price is on the pricing page — no phone call needed.
