Field employees photograph receipts into a WhatsApp bot; OCR extracts the details, policy rules approve routine expenses instantly, exceptions route to managers, and approved items post straight to payroll and the ledger. Reimbursement now takes two days instead of three weeks.

The challenge
Field teams stuffed paper receipts into envelopes and filed expense forms whenever they got back to a desk — often weeks later. Finance retyped everything, chased missing receipts and unreadable photos, and applied policy rules by memory. Reimbursements took three weeks on average, employees fronted costs out of pocket, and month-end accruals were a guessing game.

−86%The automation
We built a WhatsApp bot that accepts a receipt photo the moment an expense happens. OCR extracts vendor, date, amount, and VAT; the expense is matched to the employee and cost center, and policy rules run automatically — per-diem limits, category caps, receipt-quality checks. Compliant expenses are approved on the spot, exceptions go to the right manager with one-tap approval, and everything approved posts directly to payroll and the accounting ledger.
How it works
- 01
Snap the receipt
The employee photographs the receipt into the WhatsApp bot right at the point of expense.
- 02
OCR extraction
Vendor, date, amount, and VAT are pulled from the image and matched to the employee and cost center.
- 03
Policy check
Per-diem limits, category caps, and receipt-quality rules run automatically on every submission.
- 04
Exceptions to managers
Anything out of policy goes to the right manager with a one-tap approve or query.
- 05
Posted & paid
Approved expenses post to payroll and the ledger, with reimbursement in the next run.

The impact
Reimbursement time dropped from three weeks to two days, and 87% of expenses now clear without anyone in finance touching them. Lost receipts have disappeared, finance spends two hours a week on expenses instead of fourteen, and month-end accruals reflect reality instead of estimates.
Questions about this automation
What does an employee have to do to submit an expense?
They take a photo of the receipt and send it to the company WhatsApp bot, ideally right after paying. The bot reads the vendor, date, amount and VAT, matches the expense to the employee and cost center, and replies with the status. There is no form to fill in and no paper to keep.
How are expense policy rules applied?
Rules the finance team defines run on every submission, such as per-diem limits, caps by category and checks that the receipt image is readable. Expenses that pass are approved automatically. Anything outside policy goes to the right manager, who approves it or sends a question with one tap.
Which finance systems does the flow connect to?
Approved expenses post directly to the payroll system for reimbursement in the next run and to the accounting ledger under the correct cost center. Because entries post as soon as they are approved, month-end accruals reflect real spending. This is a multi-step build, usually rolled out in stages, starting with receipt capture.
