Code example

Parse a receipt into a ledger entry

Call DocuParse API when a receipt is uploaded, then map the extracted fields directly to your bookkeeping entry model.

// Parse a receipt and create a bookkeeping entry
async function processReceipt(receiptFile) {
  const form = new FormData();
  form.append('file', receiptFile);

  const res = await fetch('https://docuparseapi.com/api/v1/extract', {
    method: 'POST',
    headers: { 'Authorization': 'Bearer YOUR_API_KEY' },
    body: form,
  });

  const data = await res.json();

  // Map to a bookkeeping ledger entry
  const ledgerEntry = {
    date: data.date,
    vendor: data.merchant,
    amount: parseFloat(data.total),
    tax: parseFloat(data.tax),
    currency: data.currency,
    lineItems: data.line_items,
    reference: data.receipt_id,
    type: 'expense',
  };

  return await bookkeepingService.createEntry(ledgerEntry);
}

Frequently asked questions

How does receipt parsing help with bookkeeping automation?

Receipt parsing extracts structured fields — vendor, total, tax, date, and line items — from uploaded receipts. These fields can be mapped directly to bookkeeping entries, eliminating manual data entry for common business expenses.

Can I parse both receipts and invoices for bookkeeping?

Yes. DocuParse API supports both receipts and invoices. For invoices, it also extracts invoice ID, due date, and vendor details needed for accounts payable.

How do I map extracted fields to my accounting software?

The API returns named JSON fields. Map merchant to vendor, total to amount, date to transaction date, and line_items to expense line items. Most accounting software APIs accept these common fields.

Does it work with scanned receipts and invoices?

Yes. PDF, JPG, PNG, and CSV files are all supported, including scanned documents and receipt photos.
