Invoices were two weeks behind. Month-end close took 15 days. Then Ari joined the team.

Featured customer story

ServiceUp

A 15-day close became 3 days.

Ari took on invoicing and reconciliation. In the first three months, ServiceUp issued 30,000 invoices and moved 80 hours of weekly contractor work to other accounting priorities. Caitlyn got at least 10 hours a week back.

Ari

The PO lists Boston, but the invoice draft has San Francisco. Which remit-to should I use? I’ve held the Coupa submission.

You

Use Boston for this invoice. Keep checking with me when they differ.

Draft updated to Boston. Awaiting your approval to submit.

What is LedgerUp?

LedgerUp builds AI agents for the manual accounts receivable work that billing systems leave behind. Its AI billing teammate, Ari, reads signed contracts, creates and sends invoices on the right schedule, follows up on overdue payments, submits invoices to procurement portals such as Coupa, Ariba, Bill.com, and Tipalti, answers customer billing questions, matches payments to invoices, and keeps revenue recognition tied to the contract. Ari works inside Slack and email with the CRM, billing, and accounting systems B2B companies already run, including Salesforce, HubSpot, Stripe, QuickBooks, and NetSuite. LedgerUp is SOC 2 Type II compliant, and most teams are live in a week.

Who is LedgerUp built for?

B2B companies with sales-led deals, a lean finance team, and billing work that spills beyond their software. If custom contracts, customer portals, and payment exceptions keep landing on the same few people, Ari can take on the follow-through. Simple self-serve subscriptions may not need this level of support.

Do we need to replace our billing system?

No. Ari works alongside your existing billing and accounting tools. He handles the work around them, including reading contracts, following up on payments, submitting invoices to portals, and resolving exceptions.

Which systems can Ari work with?

Ari connects to tools like Salesforce, HubSpot, Stripe, Chargebee, NetSuite, QuickBooks, Xero, and Sage, plus email, Slack, e-signature tools, and procurement portals. A REST API is available for custom integrations.

How much can Ari do without approval?

That’s up to you. Review every draft, approve only key actions, or let Ari run workflows within your rules. He follows your permissions, brings you exceptions, and keeps an audit trail.

How long does it take to get started?

Some straightforward, repetitive tasks can be automated within 24–48 hours. Most teams are live in a week, with migration assistance and onboarding included. There are no setup fees. Pilots are available so you can try Ari on your own billing work before committing.

How is LedgerUp different from Stripe Billing, Maxio, or Tabs?

They are different layers. Stripe Billing and Maxio are billing engines: they store the plans and produce the invoices. Tabs runs billing through its own dashboard and billing engine. LedgerUp is an AI agent for the manual work around the engine: reading custom contracts, submitting to procurement portals, chasing collections, answering billing questions, applying cash, and keeping the audit trail tied out. Ari plugs into the billing engine, CRM, and accounting system you already use, so most teams run LedgerUp alongside Stripe or Maxio rather than instead of them.

How is our data protected?

LedgerUp is SOC 2 Type II compliant. Ari follows your access permissions and approval rules, and keeps an audit trail of his work.
