Why Connect BigCommerce to Xero?

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

BigCommerce uses a REST + Webhook API while Xero uses REST, requiring careful middleware to translate data formats between the two platforms

Reporting across BigCommerce and Xero requires painful manual exports and spreadsheet merges

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

Guest booking data in BigCommerce and operations scheduling in Xero require manual coordination

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

Customers in BigCommerce and contacts in Xero drift out of sync, leading to outdated details on invoices, emails, and reports

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

How We Help

Connecting BigCommerce (e-commerce) with Xero (accounting & finance) is one of the most requested integrations among Australian Retail & E-commerce and Hospitality & Tourism 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, BigCommerce uses a REST + Webhook API with OAuth authentication, and Xero authenticates via OAuth, which our team handles as part of the build.

Scalable Without Extra Headcount

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

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 BigCommerce means your team gets this benefit with complete, accurate data flowing in automatically.

Eliminate Manual Data Entry

Stop copying contacts between BigCommerce and Xero by hand. Our integration syncs data automatically, saving your team 8+ hours/week.

Built-In Error Handling and Alerts

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

BigCommerce to Xero Use Cases

Sync BigCommerce customers to Xero contacts

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

Scheduled reconciliation between BigCommerce 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.

Auto-generate Xero invoices from BigCommerce

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

Automated error handling and retry for BigCommerce/Xero sync

When a sync between BigCommerce 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.
