Ari connects contract terms with CRM, usage, billing, and payment data to calculate what to charge, create invoices, collect cash, and keep a reconciled audit trail.
Trusted by the fastest growing companies
Email, MSAs, usage spreadsheets, CRM records — Ari watches them all and kicks off the work the moment something lands.
Two full sentences of placeholder copy so the narrative column reserves its tallest height across all steps.
Ari working
Your contract says one thing. Stripe says another. CRM data is stale. Usage lives in the product database. Credits and voids happen after close. Payments arrive through ACH, Stripe, checks, or bank files.
Finance is left stitching together the truth manually — and proving it ties out.
That's the work Ari handles.

Ari
Reads context, resolves the exception, routes to the right system.
Finance and ops leaders are using Ari to close the gaps between contracts, billing systems, email, Slack, and the spreadsheets no one wants to maintain.
Archive case study
“After that person left, I thought I was going to need to replace him. Ari has made it so that we don't really have any plans to replace that person.”

Head of Finance and Revenue, Archive
OnShore case study
“With Ari handling the manual work, our team's energy goes toward what matters most: building client relationships and growing the business.”
Dominic
CEO, OnShore
Ari is built for the messy, repetitive revenue work that sits between systems and slows your team down.
“A new amendment just came in.”
Ari reads the amendment, diffs it against the original contract, recalculates billing, and updates the invoice before anyone asks.
“This customer short-paid us again.”
Ari checks the invoice, remittance, contract, deductions, and payment history — then explains what happened and drafts the next step.
“Usage doesn’t match what we billed.”
Ari pulls usage from the product database, compares it to the contract tiers, and flags the delta with a recommended correction.
“We got paid, but no one knows what it applies to.”
Ari matches bank activity, emails, remittance files, and open invoices — then posts the reconciliation.
“The invoice got rejected in Coupa.”
Ari finds the rejection reason, fixes the missing PO or field, and resubmits after approval.
“A customer wants the invoice changed.”
Ari checks the contract terms, updates the billing system, regenerates the PDF, and drafts the reply.
“Collections is stuck because AP needs something.”
Ari finds the blocker, drafts the customer follow-up, and keeps finance, CS, and sales aligned.
“Credits were applied after close.”
Ari traces the credit back to the original invoice, adjusts the open balance, and flags the journal entry for review.

Before Ari
After Ari
When a customer PO hits billing@, create or update the matching invoice in NetSuite, reconcile line items against the contract in Ironclad, then log into their Coupa portal and submit it with the PO number attached. If the tax code or remit-to doesn't match, ask me before sending.

Handle customer-specific billing, custom terms, split invoices, usage details, billing schedules, and invoice updates.
Follow up on overdue invoices, find missing POs, draft customer emails, escalate blockers, and keep finance and CS aligned.

Create, store, refresh, and send the Excel reports your team usually rebuilds by hand.
Finance work needs speed, but it also needs control. Ari ships with approvals, escalation, permissions, and audit built in from day one.
Ari asks for approval before important actions so your team always stays in control.

Ari respects the access, systems, and scopes you already trust across your stack.
Every decision, action, and source document is logged and easy to review later.
Your team decides what Ari can do automatically, what needs review, and where humans stay in the loop.
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.
The moment a deal closes in your CRM or a contract is signed, Ari extracts the terms and creates the right invoice or subscription.
Ari sends reminders, escalates when needed, and keeps every dollar moving without your team manually chasing customers.
LedgerUp ties out CRM, billing, and GL data so your team is not doing reconciliation by hand.
Instead of pinging finance for contract details, invoice status, renewal dates, or payment issues, your team asks Ari in Slack.
