Manual portal logins required
Procurement portal automation eliminates the manual process of logging into each customer's procurement portal to submit invoices. B2B companies often have dozens of customers using different portals (SAP Ariba, Coupa, Bill.com, Tipalti, and custom systems), each with unique requirements. LedgerUp's AI agent Ari monitors your billing inbox, reads purchase orders, matches them to invoices, and submits directly to the portal. LedgerUp customer-reported data shows teams using Ari save about 15 hours per month and reduce DSO by an average of 13 days.

Procurement portal automation FAQ
Common questions about procurement portal invoice submission automation with LedgerUp.
What is automated procurement portal invoice submission?
Procurement portal invoice submission automation uses AI to submit invoices directly to customer portals such as Coupa, SAP Ariba, Bill.com, Tipalti, and custom vendor portals. Ari reads the purchase order, matches it to the invoice, enters required fields and attachments, submits it, and reports acceptance or rejection in Slack.
Which procurement portals does LedgerUp support?
Ari can submit to any procurement portal as long as you provide the login credentials. This includes Ariba, Coupa, Bill.com, Tipalti, and custom or proprietary portals. If your team can log in and submit, Ari can too.
How does Ari know when to submit an invoice?
Ari monitors your finance, billing, or AR email inbox. When a procurement team sends a submission request, a new purchase order arrives, or an invoice needs to be submitted, Ari picks it up and handles it automatically.
Does Ari handle PO matching?
Yes. Ari reads the purchase order, matches it to the corresponding invoice, and updates any fields that need to change (PO numbers, amounts, line items) so the submission matches what the portal expects and doesn't get rejected.
What happens if Ari runs into a problem during submission?
Ari notifies your team in Slack and asks for the specific information or clarification needed. There are no silent failures. If something is wrong with the PO, the portal rejects the submission, or a field is missing, your team knows immediately and can resolve it quickly.
How does this reduce DSO?
Most DSO inflation from procurement portals comes from delayed submissions, specifically invoices sitting in someone's inbox for days before being submitted. Ari submits invoices as soon as they're ready, eliminating that delay. LedgerUp customer-reported data shows an average 13-day reduction in DSO for teams using this workflow.
How is this different from other procurement portal submission services?
Most portal submission services still rely on a human team manually logging into portals and entering data, which is why they're slower and more error-prone. Ari automates the entire process end-to-end: reading the PO, matching it to your invoice, submitting to the portal, and reporting status, all without manual intervention.
Can I check the status of a submission?
Yes. You can ask Ari in Slack at any time. Just say "What's the status of the Acme invoice?" and he'll tell you whether it's been submitted, accepted, rejected, or is pending payment.
