Why Connect MYOB to Square?

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

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

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

Site crews rely on MYOB while the office uses Square, so neither team sees the full picture until end of day

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 MYOB and Square wastes hours every week that could be spent on revenue-generating work

MYOB limitations compound the integration challenge: third-party app integrations are more limited than Xero, with fewer modern SaaS tools offering native MYOB connections

MYOB to Square Use Cases

Sync MYOB contacts to Square customers

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

Synchronise inventory catalogue between MYOB and Square

Product data, pricing, and stock levels stay consistent across both platforms. When a inventor is added, updated, or discontinued in MYOB, Square reflects the change within seconds.

Automated error handling and retry for MYOB/Square sync

When a sync between MYOB and Square 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.

Scheduled reconciliation between MYOB and Square

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.
