Saasybill

Saasybill is a subscription billing management solution that helps B2B SaaS companies on Xero automate recurring invoicing without moving their financial data out of Xero. Most billing tools take invoicing out of the accounting system and run it through their own platform. That means revenue data lives somewhere else, Xero reporting is incomplete, and reconciliation becomes a job in itself. Saasybill works the other way. Invoices are created directly inside Xero at every renewal, keeping it as the source of truth for all financial data. Connect to Xero, define pricing plans, attach subscriptions to customers, and billing runs automatically from that point. Proration is calculated to the day for mid-cycle changes, upgrades, and downgrades, with the correct invoice pushed to Xero without manual input. A complete audit trail is maintained for every change. Saasybill is built for SaaS companies that have outgrown manual invoicing and spreadsheet-based subscription tracking but do not need the complexity or cost of enterprise billing platforms. It handles both monthly and annual contracts, supports multiple pricing models per customer, and is designed for businesses that invoice via bank transfer rather than card. Because invoices are generated inside Xero rather than synced from an external system, there is no partial data transfer and no reconciliation work required at month end. Key features: - Automated invoice generation directly inside Xero at every renewal - Five billing models: flat fee, per-seat, volume, tiered, and stairstep - Day-accurate proration for mid-cycle plan changes and upgrades - Add-ons for optional charges layered on top of base plans - No transaction fees, flat subscription pricing only Setup connects directly to an existing Xero account. 14-day free trial, cancel anytime.
