Every receipt becomes durable proof, and every claim is tracked all the way to repaid — so an advance never quietly becomes your personal loss.
Capture, track, and get reimbursed — without paper, Excel, or a folder of LINE photos.
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.
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-IDs checked with the mod-11 algorithm, money and VAT validated on entry — so a claim isn’t rejected on a typo.
Buddhist-era dates read and converted correctly, the way every Thai receipt and finance system expects.
Collect valid e-receipts through the year so the annual deduction (up to ฿50,000) isn’t a December scramble.
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.
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.
Doctor meetings come with compliance rules. Bundle every receipt with its sign-in sheet and attendee list, and clear the approval the first time.
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.”
“A claim got rejected for ฿12,000 because the sign-in sheet wasn’t attached. The receipt was fine — the bundle wasn’t.”
“Right now it’s paper, Excel, and LINE photos. By the time I file, half the thermal receipts have already faded to nothing.”
A receipt vault only works if you trust it with the proof that protects your money.
Your receipts belong to you and travel with you across employers and jobs — we never sell them. Export everything, any time.
Receipts and any third-party tokens are encrypted at rest, with keys kept outside the database — defense in depth, not an afterthought.
Every input is re-validated server-side. Tax-grade rules run on the backend, not just in the app, so your records hold up.
The short version of what billsup.ai is and how it protects your money.
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.
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.
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.
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.
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.
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.
