High bill volume, want full control, and data must never leak
The more bills a month, the more a per-bill service costs. This system is built for teams that want their own system, want to set their own booking rules, and don't want customer bills sitting on anyone else's cloud.
The more you process, the more you save
The model runs on your own machine, so there's no per-bill cost. Ten bills or ten thousand, the electricity bill stays the same.
You control every rule
The chart of accounts, the signatories, the company-specific rules stay in your hands. The system adapts to your work, not the other way around.
Bills never leave your system
The real system runs inside your organization, so personal-data requirements are met without relying on any provider's promise.

Output imports into FlowAccount · PEAK · Express and any accounting system that accepts file import
We don't let AI do the math for you
AI has one job: transcribe the numbers and text off the bill exactly as printed. Addition, tax, and the call on whether to trust a figure belong to a fixed calculator that recomputes everything a second time. If the numbers don't add up, the system sends it to a human, it doesn't guess.
Start by telling the system about your company
Answer a few short questions, no accounting jargon required. The system assembles a COMPANY.md context file for you. This file stays with you, attach it back next time and the system remembers your company, and you can carry it straight into the real on-premise system.
No receipt for an expense? We draft a certificate in lieu of receipt (ใบรับรองแทนใบเสร็จ) for you
Taxi fares, market purchases, coin-operated parking, expenses like these will never come with a receipt. They can't be booked for tax purposes until an authorized person in the company signs off. The system pulls these expenses out, drafts the certificate following Revenue Department guidance, fills in the signatory name you set up, and emails it to you along with the Excel file in one pass.
Already know which bills are incomplete? Fill in the two fields below and upload them directly, no need to wait for the system to sort them. Uses the same quota as the combined extraction.
Fill this in here or in the first console, it's the same data either way, the system keeps them in sync.
The system drafts the certificate, fills in the signatory name from your saved context, and emails it to you along with the Excel file.

Before you try it
How many bills can I try for free, and how is it counted?
30 bills a month, counted per email address and per buyer company shown on the bills. Upload and walk away, the system emails you the file when it's done.
Can it read handwritten bills?
Partially, but the system never guesses. Anything it isn't confident about always goes to a human for confirmation, a number that fails verification never slips silently into the file. The on-premise system can also be tuned to the documents you see regularly, so accuracy on your bills keeps improving with use.
How safe is my bill data?
Trial mode processes on our server and deletes everything the moment results are sent back. The real system installs on your organization's own machine, so bills never touch anyone's cloud, PDPA compliance comes from how the system is built, not from a promise.
Can I import the output file straight into my accounting system?
Yes. The figures in the file are real numbers, not text. Dates support the Buddhist Era, and the file states clearly whether each price already includes VAT. Columns are laid out to match the import screens of FlowAccount, PEAK, and Express directly.
What is a certificate in lieu of receipt (ใบรับรองแทนใบเสร็จ), and when is it used?
A document an authorized person in the company signs to certify that an expense genuinely happened for the business. It's used for expenses where you can't get a receipt from the payee, taxi fares, market purchases, coin-operated parking, following Revenue Department guidance. When the system finds an incomplete bill, it drafts one automatically, or you can upload directly to the certificate console. Same quota either way.
How is this different from pay-per-bill extraction services?
Typical services charge per bill, and your bills go up to their cloud. This system installs once on your own machine, after that there's no per-bill cost. The more bills you process, the more you save, and you own both the system and the data.
