Your team should not be the glue between systems.
A deal closes. A contract gets signed. Then someone has to read the terms, build the invoice, chase the PO, follow up for payment, reconcile the books, and answer the same billing questions over and over.
Deal closes. Invoice sends.
The moment a deal closes in your CRM or a contract is signed, Ari extracts the terms and creates the right invoice or subscription.
Invoice goes overdue. Ari follows up.
Ari sends reminders, escalates when needed, and keeps every dollar moving without your team manually chasing customers.
Payment lands. Books reconcile.
LedgerUp ties out CRM, billing, and GL data so your team is not doing reconciliation by hand.
Your team has a question. Ari answers.
Instead of pinging finance for contract details, invoice status, renewal dates, or payment issues, your team asks Ari in Slack.

Your team has a question. Ari answers.
Instead of pinging finance for contract details, invoice status, renewal dates, or payment issues, your team asks Ari in Slack.
“Our sales team used to ping me 20 times a day on billing questions. Now they just ask Ari in Slack.”
100 Emails a Day. Zero From You.
You're digging through threads, cross-referencing systems, and writing the same responses over and over. Ari handles it and only pings you when something actually needs a human.
“I was drowning in emails... We would get 100+ emails a day on billing questions. Ari has saved us so much time and effort.”
PO Received. Invoice Sent. Done.
You're chasing customers for PO numbers before you can even send an invoice. Ari proactively asks for the PO, matches it to the deal, and sends the invoice the moment it's confirmed.
“It was so hard staying up to date with POs and I was always chasing people for them. Now this is 5 hours of my week I don't have to worry about.”
Usage In. Invoices Out.
You're exporting CSVs, running formulas, and praying the numbers tie out before the invoice goes out. Ari ingests your usage data, meters it against each contract, and bills your customers automatically - every cycle, every time.
“LedgerUp made usage so easy. They just connected to our usage data and now usage gets billed automatically. It's a game changer.”
All 5 contracts rated and invoiced - zero manual work.
One workflow. Full context. No manual handoffs.
