Keying vendor invoices from email into your books?
MailParse reads each invoice email, pulls the fields you name (vendor, invoice number, amount, due date), and exports clean rows to Excel, CSV, or JSON for your AP process. Try the invoice data extractor, or read the workflow below.
Accounts payable teams live in the inbox. Vendors email invoices, subscription renewals, and payment reminders, and someone reads each one, types the vendor name, invoice number, amount, and due date into the accounting system, then files it for approval. For a small firm that is a few minutes a day. For a business paying dozens of vendors, manual AP data entry is hours of typing and a steady source of errors that surface at month end.

How do I automate accounts payable data entry from email?
To automate accounts payable data entry from email, connect the inbox that receives invoices to an email parser, name the fields your books need (vendor, invoice number, invoice date, due date, amount, PO number), and the parser writes each invoice email to a row and exports it as Excel, CSV, or JSON for import. That removes the retyping step, so your team reviews and approves instead of keying.
What invoice fields can a parser pull from an email?
A parser reads the fields written in the email body or an HTML invoice table: vendor name, invoice number, invoice and due dates, subtotal, tax, total, payment terms, and a PO number when the vendor includes one. Each of those becomes a column you choose. When an invoice is a line-item table in the body, each line can become its own row tied to the invoice number, which is what you need for GL coding.
| Step | Manual AP | Parser-assisted AP |
|---|---|---|
| Capture invoice data | Type each field by hand | Parsed into rows automatically |
| Review and approve | Person checks each entry | Person checks a clean sheet |
| Import to accounting | Re-key into the system | Import the CSV directly |
What about invoices sent as PDF attachments?
Be clear on this: MailParse reads the email message, not the contents of a PDF attachment. It records each attachment by filename, type, and size, and parses any invoice fields the vendor writes into the email body or an HTML table. When the numbers live only inside an attached PDF, that is a document-extraction job. For teams with high PDF volume, a dedicated accounts payable automation tool that runs OCR on attachments is the right fit; a parser handles the many invoices whose details are in the email itself.
How do I import parsed invoices into QuickBooks or Xero?
Export the parsed invoices as a CSV mapped to the columns your accounting software expects, then use its import. QuickBooks and Xero both accept a bill or transaction CSV with vendor, date, amount, and reference columns. Because the parser lets you name the fields, you can match your import template exactly and skip the cleanup pass. See using an email parser for QuickBooks for the field mapping details.
Does this reduce data entry errors?
Yes, in two ways. The parser reads the same value every time, so a transposed invoice number or a misread amount from tired typing disappears. And because your team reviews a structured sheet instead of retyping from scratch, the remaining check is faster and catches the exceptions that matter. You still keep a human approval step; the parser removes the mechanical keystrokes, not the judgment.
Getting started with AP email parsing
Start with a week of real invoice emails to confirm the vendor, invoice number, amount, and due date come back correctly. Connect the AP inbox or upload saved messages, map the fields, and export an Excel workbook or an accounting-ready CSV. Accountants comparing tools will find the best email parser for accountants rundown useful, and the extract invoice data from email workflow is built for exactly this AP job.
