Document Processing Automation for Singapore SMEs

Stop rekeying vendor invoices, purchase orders, and onboarding documents. We build extraction, validation, and matching workflows that route structured data into your accounting tool, ERP, or spreadsheets — with human review where it matters.

The problem

Documents arrive faster than your team can key them in

Invoices land in shared inboxes, POs sit in PDF attachments, and onboarding documents pile up in WhatsApp. Manual entry creates errors, delays payment cycles, and creates real exposure to duplicate payments and missed approvals.

  • Vendor invoices manually entered into Xero or QuickBooks.
  • PO and invoice mismatch caught only after payment.
  • Onboarding documents lost in email and WhatsApp threads.
  • No clean audit trail for finance or compliance review.

What Paddly builds

Extract, validate, match, route — with humans on exceptions

Routine documents are processed automatically. Anything outside the rules is queued for human review with the full source attached. You stay in control of approvals while removing the typing.

Example workflow

Vendor invoice → matched, routed, posted

  1. 1

    Invoice arrives in finance@ inbox

    A new email with a PDF attachment triggers the workflow.

  2. 2

    Fields extracted and normalised

    Vendor, invoice number, line items, totals, GST, and PO reference are extracted into a structured record.

  3. 3

    Three-way match against PO and delivery note

    The workflow checks the matching PO and goods-receipt note. Quantities and prices are reconciled.

  4. 4

    Routed for approval

    Matched invoices flow straight to the approver. Mismatches go to the exception queue with deltas highlighted.

  5. 5

    Posted to accounting

    On approval, the invoice is created in Xero/QuickBooks with line items, GST, and the source PDF attached.
