Tired of Submitting Invoices to
Coupa and Ariba?
Ariba. Coupa. Bill.com. Tipalti. Your team is logging into a different portal for every customer. Ari reads the PO, matches the invoice, and submits it automatically.
Ari does the portal work for you
Log in, find the right fields, match the PO, click submit. Ari handles every step so your team never has to.
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 (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. Teams using Ari save 15 hours per month and reduce DSO by an average of 13 days.
The procurement portal nightmare
Submitting invoices to procurement portals is always an afterthought, until it's the reason you're not getting paid.
Every customer uses a different portal
Ariba, Coupa, Bill.com, Tipalti, custom portals. Your team is logging into a dozen different systems just to submit invoices. Each one has its own rules, required fields, and quirks.
Delayed submissions = delayed payments
An invoice that sits in someone's inbox for three days before getting submitted to a portal is three days of DSO you didn't need. Multiply that across every customer and it adds up fast.
Tracking status is impossible
Which invoices were submitted? Which ones were rejected? Which ones are stuck waiting on a PO match? Nobody knows without logging into every portal individually.
30-email threads with procurement
A PO number is wrong. A field is missing. The amount doesn't match. Now you're deep in an email thread with procurement trying to piece together what went wrong and what the current state even is.

Ari handles the entire workflow. No manual logins, no copy-pasting, no portal-hopping.
Ari monitors your billing inbox
Add Ari to your finance, billing, or AR email. When a procurement team sends a portal submission request or a new PO comes in, Ari picks it up automatically.
Ari reads the PO and prepares the invoice
Ari reads the purchase order, matches it against your invoice, and updates any fields that need to change (amounts, line items, PO numbers) so the submission matches what the portal expects.
Ari submits to the portal
Using the credentials you provide, Ari logs into the procurement portal and submits the invoice with the correct data, attachments, and required fields. No manual entry.

Procurement portal automation FAQ
Common questions about automating invoice submissions to procurement portals with LedgerUp.
What is automated procurement portal invoice submission?
Automated procurement portal submission uses AI to take invoices and submit them directly to your customers' procurement portals (Ariba, Coupa, Bill.com, Tipalti, and others) without anyone on your team manually logging in, entering data, or uploading documents.
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. Customers using this feature see an average 13-day reduction in DSO.
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.
