Setting it up
Setup takes 5-15 minutes depending on whether you have an existing Microsoft 365 account. Prerequisites: active Microsoft 365 account with admin access, your InvoiceQuickly workspace, and the relevant API permissions or OAuth authorization. From Settings → Integrations → Microsoft 365, follow the connection flow (OAuth for most, API key for some specialized tools). The integration syncs bidirectionally where supported — invoice creation in one system reflects in the other. Initial setup includes mapping data fields between systems (customers, products, payment methods, tax codes).
Best practices
Define one source of truth for customer data
When you connect Microsoft 365, decide which system owns customer records. Most teams keep their primary CRM/ERP as the source of truth and let invoices sync into it. This prevents duplicate customer creation and reconciliation issues.
Test with a small batch before production rollout
Before syncing all historical data or going live for daily operations, test with 5-10 invoices to verify field mapping, tax handling, and payment workflow. Adjust configuration based on test results.
Reconcile sync status weekly
Network failures, OAuth expirations, and edge cases occasionally cause sync gaps. A weekly reconciliation (compare invoice counts in both systems) catches issues early before they accumulate.
Document the integration scope for your team
Write a brief internal doc (one page) covering: which workflows use the Microsoft 365 integration, who owns reconciliation, what to do when sync fails. Reduces support overhead as the team grows.
Common issues
Sync stops after working initially
Most common cause: OAuth token expired (typically 60-100 days depending on the Microsoft 365 platform). Reconnect via Settings → Integrations → Microsoft 365. Set a reminder to refresh authorization every 60 days for critical integrations.
Field mapping creates duplicate or missing data
During initial setup, the field mapping between Microsoft 365 and InvoiceQuickly may not catch every edge case. Adjust mapping in Settings → Integrations → Microsoft 365 → Field Mapping. Re-sync affected records after fixing.
Rate-limit errors during high-volume operations
Microsoft 365 APIs typically allow 100-1000 calls per minute. Bulk operations (importing all customers, syncing 1000+ historical invoices) can hit rate limits. InvoiceQuickly handles backoff automatically; if you see persistent errors, retry during off-peak hours.
