LedgerUp

LedgerUp is an accounting journal entries tool. LedgerUp provides an AI billing teammate called Ari that reads signed contracts, drafts and submits invoices, chases overdue payments, files documents into procurement portals, answers billing inbox requests, and reconciles incoming payments against open invoices across existing finance systems.

LedgerUp is a financial operations platform built around Ari, an AI billing teammate that handles the manual accounts receivable work left over after billing systems finish their part. The core idea is narrow and practical: signed contracts, customer emails, procurement portals, and bank payments all contain information that someone has to read, retype, and reconcile. LedgerUp assigns that reading and retyping to an agent, while the finance team keeps control of the decisions. In practice Ari covers five connected workflows. It reads signed agreements and turns terms into billing schedules and invoice drafts, including quarterly or multi-part arrangements. It drafts overdue follow-ups after checking the open balance and prior customer correspondence. It submits invoices and supporting purchase order documents into portals such as Coupa and Ariba and stores the submission receipt. It reads the billing inbox, applies context to requests like PO changes, and prepares revised invoices as replies. Finally it matches incoming payments to open invoices across accounting and billing systems and updates the records. The product is aimed at finance and accounting teams at growing companies, particularly controllers and billing operations staff who are issuing volume invoices and spending hours on exceptions. LedgerUp is explicit that this is not a full replacement for an ERP or a subscription billing engine. It sits on top of HubSpot, Salesforce, Stripe, QuickBooks, NetSuite, DocuSign, Chargebee, Sage, Slack, and similar systems, and the homepage states that 50 or more integrations are supported alongside custom connectors for any API-accessible system. The control model is the distinguishing feature. Teams choose a mode: draft for review, approve key actions, or run within set rules. Mismatches, such as a remit-to address that differs between a purchase order and an invoice draft, get escalated with context rather than silently resolved. Every action and source document is logged for later audit. LedgerUp publishes comparison pages against Stripe Billing, Tabs, Upflow, HighRadius, and Maxio, which positions it as a layer rather than a swap for those tools. Onboarding is claimed to take about a week for a first workflow.
