Learn how vendors submit invoices to BillerPlus.
Two ways to submit
Web Form
Visit the company’s submission URL, fill out the form, and upload your invoice.
Send your invoice as an email attachment to the inbox’s email address. AI extracts the data automatically.
Both methods result in the same experience—your invoice appears in the company’s dashboard and you receive status updates via email.
Using the web form
Accessing the form
Vendors access the submission form via a unique URL. No account or login is required—simply visit the link and start submitting.
The URL looks like:
https://billerplus.com/submit/company-name
https://billerplus.com/submit/company-name/inbox-name
Required information
Vendors must provide the following to submit an invoice:
| Field | Description |

Finding the email address
Each inbox has a unique email address:

What to send
Just attach your invoice document and send. You can optionally include: - Invoice number in the subject line - Additional context in the email body
