Your billing stack has tools. It doesn't have a worker.
Most billing platforms give you dashboards and workflows — then leave you to operate them. Your team still manually reads contracts, creates invoices, chases payments, and reconciles every transaction. That's not automation. That's a to-do list with better UI.
2-5%
revenue leakage
Custom contracts, mid-cycle changes, and billing errors quietly drain revenue every quarter.
40+ hrs/month
on manual billing ops
Finance teams spend a full work week every month on manual invoicing, reconciliation, and collections.
45+ day DSO
average collection time
Late invoices and manual follow-ups slow down cash flow when you need it most.
3-6 months
to switch billing systems
Most teams can’t afford a migration. But they also can’t afford to keep doing billing ops manually.
You don't need to switch billing systems. You need a platform that connects to yours and actually does the work.
A complete billing and revenue platform
Everything your finance team needs to manage contracts, invoicing, payments, reconciliation, and reporting — all in one place.
Deals close. Billing starts.
LedgerUp reads your contracts, extracts billing terms, pricing structures, and renewal dates — then automatically sets up the billing schedule. No handoff meetings. No ops tickets.
Invoices that handle themselves
Complex pricing, usage tiers, mid-cycle amendments — LedgerUp generates accurate invoices for every scenario and sends them on time, every time. Even the messy ones.
Every dollar, accounted for
Payments and usage data reconcile against invoices in real time. Discrepancies get flagged before they become problems. No more month-end spreadsheet marathons.
Get paid without the awkward follow-ups
Past-due invoices get handled automatically — friendly reminders, escalation paths, and recovery workflows that protect your customer relationships while keeping cash flowing.
Your CRM, always up to date
Ari syncs invoice status, payment status, renewal dates, and collections status back to HubSpot and Salesforce - so your GTM team always has the full picture.
Connects to the tools you already use
LedgerUp layers on top of your existing stack. No migration. Just connect and let Ari get to work.
Don't see yours? We'll still connect.
Now meet Ari — the AI that does the work
Other platforms stop at automation. LedgerUp goes further. Ari is an AI agent built into the platform that actually handles billing requests — in Slack, over email, and from your support tools. Your team isn't just getting software. They're hiring a teammate.
Works in Slack
Ari lives in your team's Slack. She proactively handles billing tasks, answers questions, and surfaces decisions that need a human — right where your team already works.
Handles email requests
When customers email about billing questions, invoice requests, or payment issues — Ari reads the email, pulls the relevant data, and drafts a response.
Plugs into support platforms
When a billing ticket comes in, Ari pulls the customer's billing history, identifies the issue, and resolves it — or escalates with full context.
New contract signed with Acme Corp — $24K/year, net-30, quarterly billing. I've set up the billing schedule and the first invoice goes out Monday. Anything you'd like me to adjust?
Looks good, thanks Ari
Done. I've also updated the Acme Corp record in HubSpot and Salesforce - billing status, contract terms, and next renewal date are synced. I'll follow up if payment isn't received by the due date. ✅
Full control. Full visibility. Always.
Ari is powerful — but your team sets the rules. Every action is logged, every decision is auditable, and you decide how much autonomy Ari gets.
Approval workflows
Set approval requirements by amount, customer, or action type. Ari asks before acting on anything that crosses your thresholds.
Complete audit trail
Every action Ari takes is logged with timestamps, context, and reasoning. Built for teams that take compliance seriously.
Adjustable autonomy
Start with full oversight. As you build confidence, expand what Ari handles on her own. You set the pace. And because LedgerUp connects to your existing systems, there’s no migration risk to get started.
