Why Connect Saasu to Xero?

No single source of truth when contacts live in two disconnected tools, so staff second-guess which system has the correct information

Manually copying data between Saasu and Xero wastes hours every week that could be spent on revenue-generating work

Invoice and payment data is re-entered between Saasu and Xero manually, doubling the work and risking GST errors at month-end

Online orders in Saasu and in-store inventory in Xero are never in sync, frustrating customers

Saasu limitations compound the integration challenge: significantly smaller user base and integration ecosystem than Xero and MYOB, limiting the range of third-party apps that connect natively

Contacts in Saasu and contacts in Xero drift out of sync, leading to outdated details on invoices, emails, and reports

Xero adds complexity: advanced reporting and custom financial reports are limited on lower plans - detailed management reporting often requires exporting to spreadsheets

How We Help

Every week without this integration costs your Professional Services and Retail & E-commerce business 8+ hours/week in manual data handling between Saasu and Xero. Our Harvard-educated consultants build a sync that eliminates that waste permanently. On the technical side, Saasu uses a REST API with OAuth authentication, and Xero authenticates via OAuth, which our team handles as part of the build.

Unified Contacts Across Both Platforms

Contacts in Saasu and contacts in Xero stay perfectly aligned. Every update, whether it is a new phone number, email change, or company association, is reflected in both systems within seconds.

Real-Time Visibility Across Teams

When a record updates in Saasu, every team member working in Xero sees the change instantly. No lag, no stale dashboards, no conflicting reports.

Scalable Without Extra Headcount

As your data volume grows, the integration scales with you. No need to hire additional admin staff to keep Saasu and Xero in sync, even as your business doubles.

Built-In Error Handling and Alerts

Our integrations include automatic retries, error queuing, and real-time notifications. If something fails between Saasu and Xero, your team knows immediately and the system self-recovers where possible.

Saasu to Xero Use Cases

Scheduled reconciliation between Saasu and Xero

A daily or weekly reconciliation job compares records across both platforms, flags discrepancies, and generates a mismatch report. Catches sync gaps before they become accounting headaches.

Automated error handling and retry for Saasu/Xero sync

When a sync between Saasu and Xero fails due to a rate limit, network issue, or validation error, the integration retries automatically with exponential backoff. Your team is alerted only when intervention is genuinely needed.

Auto-generate Saasu invoices from Xero

When records are completed in Xero, an invoice is automatically created in Saasu with the correct contact, line items, GST rates, and payment terms. Eliminates the delay between finishing work and sending the invoice.
