Why Connect Wave to Xero?

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

Customers in Wave and contacts in Xero drift out of sync, leading to outdated details on invoices, emails, and reports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

New team members take longer to onboard because they must learn manual workarounds to keep Wave and Xero aligned

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

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

How We Help

Connecting Wave (accounting & finance) with Xero (accounting & finance) is one of the most requested integrations among Australian Professional Services and Retail & E-commerce businesses. This integration eliminates the manual transfer of contacts and invoices data, reducing errors and freeing up your team to focus on growth. On the technical side, Wave uses a REST API with OAuth authentication, and Xero authenticates via OAuth, which our team handles as part of the build.

Unified Customers Across Both Platforms

Customers in Wave 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 Wave, every team member working in Xero sees the change instantly. No lag, no stale dashboards, no conflicting reports.

Custom-Built for Your Workflow

Unlike generic connectors, we build integrations tailored to how your business actually uses Wave and Xero. Custom field mappings, business rules, and error handling included.

Unlock Xero Value

Xero stands out because australian-first design means GST, BAS, and Single Touch Payroll are built in rather than bolted on as afterthoughts. Integrating it with Wave means your team gets this benefit with complete, accurate data flowing in automatically.

Wave to Xero Use Cases

Sync Wave customers to Xero contacts

When a customer is created or updated in Wave, the corresponding contact record in Xero is automatically created or updated. Contact details, company associations, and custom fields are all mapped.

Scheduled reconciliation between Wave 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 Wave/Xero sync

When a sync between Wave 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 Wave invoices from Xero

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