Snap it before it fades

Point your camera at any receipt. billsup.ai reads the merchant, date, amount, VAT and tax-ID — then files it where thermal paper can’t fade and a wallet can’t lose it.

  • Merchant, date, amount & 7% VAT extracted automatically
  • Tax-ID validated (mod-11) and ใบกำกับภาษี flagged
  • Buddhist-era (พ.ศ.) dates handled correctly

Built for Thai tax reality

Not a generic scanner — built for how Thailand actually reimburses

Most expense apps were built for Western forms. billsup.ai is built around ใบกำกับภาษี, 7% VAT, พ.ศ. dates, and the Easy E-Receipt deduction.

Tax-grade validation

Tax-IDs checked with the mod-11 algorithm, money and VAT validated on entry — so a claim isn’t rejected on a typo.

พ.ศ. ↔ ค.ศ. native

Buddhist-era dates read and converted correctly, the way every Thai receipt and finance system expects.

Easy E-Receipt ready

Collect valid e-receipts through the year so the annual deduction (up to ฿50,000) isn’t a December scramble.

Who it’s for

Built for the people who front their own money

When your own cash is on the line, a faded receipt isn’t paperwork — it’s a personal loss. These are the two jobs we built for first.

Field & SI engineers

You advance ฿10k–50k for a job, then wait months

Front the materials, finish the work, and chase repayment for one to three months. billsup.ai holds the proof and the running total so nothing you advanced slips away.

Your claims get rejected without the right documents

Doctor meetings come with compliance rules. Bundle every receipt with its sign-in sheet and attendee list, and clear the approval the first time.

From the field

The pain we kept hearing in interviews

Grounded in conversations with the people who live this every month.

“I fronted ฿45,000 for a site job and the advance was delayed for months. One faded receipt and that’s my money gone — not the company’s.”

Trust by design

Your proof. Your data. Locked down.

A receipt vault only works if you trust it with the proof that protects your money.

You own your data

Your receipts belong to you and travel with you across employers and jobs — we never sell them. Export everything, any time.

Encrypted at rest

Receipts and any third-party tokens are encrypted at rest, with keys kept outside the database — defense in depth, not an afterthought.

Validated at the boundary

Every input is re-validated server-side. Tax-grade rules run on the backend, not just in the app, so your records hold up.

Questions & answers

Frequently asked questions

The short version of what billsup.ai is and how it protects your money.

What is billsup.ai?

billsup.ai is a receipt and reimbursement tracker for Thailand. It turns every receipt into durable, searchable proof, extracts the merchant, date, amount, 7% VAT and tax-ID, and tracks each claim from submitted to outstanding to repaid — so you never lose money you’re owed.

Who is billsup.ai for?

It’s built first for people who advance their own cash: field and systems-integration engineers who front ฿10,000–50,000 for a job and wait months to be repaid, and medical reps whose claims get rejected without the right attached documents. Office workers and freelancers tracking reimbursements and Easy E-Receipt deductions benefit too.

How does billsup.ai track what I’m owed?

Every receipt becomes a claim with a state — submitted, outstanding, or repaid — and an age. billsup.ai shows a live total of every baht owed to you and warns you when a claim has aged too long, so nothing slips through before you’re repaid.

Does it support ใบกำกับภาษี and Thai tax rules?

Yes. billsup.ai is built around Thai tax reality: it validates tax-IDs with the mod-11 algorithm, checks 7% VAT, handles Buddhist-era (พ.ศ.) dates, flags full tax invoices (ใบกำกับภาษี), and helps you collect valid e-receipts for the annual Easy E-Receipt deduction of up to ฿50,000.

Is my data private and secure?

Your receipts belong to you and are portable across employers and jobs — we never sell your data. Receipts and any third-party tokens are encrypted at rest with keys kept outside the database, and every input is re-validated server-side. You can export everything at any time.

How much does billsup.ai cost?

billsup.ai is free to start with no credit card required. Paid individual and team tiers for the owed-money ledger and compliance features are planned, but you get value from the first receipt you scan.
