Saasybill - 2026 Pricing, Features, Reviews & Alternatives

Saasybill is a subscription billing and management software designed for B2B businesses that use Xero as their accounting platform. The application automates recurring billing processes by synchronizing directly with Xero and eliminates manual invoice creation, spreadsheet based tracking, and month end reconciliation. It invoices through Xero to avoid transaction fees typically charged by card processors. The platform accommodates varying billing frequencies and contract terms, reducing the potential for manual errors in complex subscription management scenarios.

Saasybill supports five distinct billing models to accommodate diverse pricing strategies, including flat fee, per unit, tiered, volume, and stairstep pricing structures. Built in proration capabilities calculate day accurate adjustments automatically when mid cycle changes occur, such as plan upgrades or unit modifications. Monthly and annual billing cycles are processed automatically, with renewal events triggered on the scheduled date for each subscription. Individual pricing rules at the customer level allow custom overrides and plan specific configurations across the customer base.

The platform manages subscription lifecycle events including trial to paid conversions, plan downgrades, and subscription completions with predefined cycle limits. Automated credit note generation in Xero handles refunds or billing corrections, ensuring accurate financial records throughout the subscription lifecycle. A complete audit trail records each billing event, subscription change, and invoice modification for transparency and compliance. All invoices generated by Saasybill are pushed to Xero, where they appear as standard Xero invoices ready for delivery and reconciliation.

Saasybill integrates natively with Xero through a bidirectional synchronization that keeps contacts, invoices, and billing records aligned between both systems. The integration operates continuously without manual triggers, processing renewals, upgrades, and invoice generation based on each subscription configuration. This dedicated billing layer slots into existing Xero workflows and removes the need for additional payment processing systems or manual intervention. It is intended for software related businesses that require reliable, automated subscription management with minimal administrative overhead.
