Why Connect Expensify to Sage?

Client engagement details in Expensify and time-tracking data in Sage do not align, making billing inaccurate

Reporting across Expensify and Sage requires painful manual exports and spreadsheet merges

Sage adds complexity: migration between Sage products (e.g., Sage 50 to Sage Intacct) is not seamless and often requires professional assistance

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

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

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

Transaction data in Expensify requires manual verification against Sage, increasing audit risk

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

How We Help

Connecting Expensify (accounting & finance) with Sage (accounting & finance) is one of the most requested integrations among Australian Professional Services and Financial Services businesses. This integration eliminates the manual transfer of expenses and reports data, reducing errors and freeing up your team to focus on growth. On the technical side, Expensify uses a REST API, and Sage authenticates via OAuth, which our team handles as part of the build.

Amplify Expensify Strengths

Expensify excels because smartScan receipt capture uses AI to extract merchant, date, amount, and currency from photos with high accuracy, making expense logging genuinely effortless. Connecting it to Sage ensures that advantage flows through your entire workflow rather than staying siloed in one tool.

Real-Time Visibility Across Teams

When a record updates in Expensify, every team member working in Sage 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 Expensify and Sage 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 Expensify and Sage, your team knows immediately and the system self-recovers where possible.

Expensify to Sage Use Cases

Scheduled reconciliation between Expensify and Sage

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 Expensify invoices from Sage

When records are completed in Sage, an invoice is automatically created in Expensify 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 Expensify/Sage sync

When a sync between Expensify and Sage 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.
