The problem

The hard part isn't sending invoices. It's knowing what to bill.

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.

Archive case study

Archive
5x reduction in admin hours

Archive cut finance admin from 6 hours a week to under 1.

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.

Real work

Give us the work your team keeps avoiding.

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.

Operating layer, not a replacement

Keep your stack. Replace the manual work around it.

LedgerUp does not ask you to rip out Stripe, Chargebee, NetSuite, QuickBooks, Salesforce, or your customer portals. Ari works across the systems you already use, follows your approval rules, and leaves an audit trail behind every action.

  • Reads PDFs, contracts, remittance files, invoice attachments, and customer emails
  • Drafts changes before taking action
  • Routes approvals to the right person
  • Leaves a clear audit trail for every step

Why LedgerUp

Why teams use LedgerUp instead of another automation tool.

LedgerUp is built for judgment-heavy revenue work, not just simple automations.

Zapier breaks on exceptions

Ari reads context, handles messy inputs, and asks for approval when judgment is needed.

RPA needs brittle scripts

Ari can work from emails, PDFs, spreadsheets, contracts, remittance files, and portals.

Offshore teams still need management

Ari does the repetitive work, shows its reasoning, and escalates only the unusual cases.

Billing systems handle the clean path

LedgerUp handles the messy edge cases around them.

Example workflows

We make them one less thing to worry about.

Contracts, invoice changes, cash application, collections, and portals all follow the same pattern: Ari gathers context, updates the right systems, and asks for approval when it matters.

Meet Ari

Train Ari the way you'd train a new teammate.

You

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.
