Accounting Integrations
This article walks through how Engine's accounting integrations work: what they do, why they're worth setting up, and what to expect once you turn one on. If your finance team uses QuickBooks Online or NetSuite, this integration keeps your books in sync with your Engine activity automatically.
Available integrations
Engine currently integrates with QuickBooks Online and NetSuite. Select your platform below for step-by-step setup instructions.
How the integration works
An accounting integration connects Engine directly to your accounting system so your travel and card transactions sync automatically.
Once it's set up, this integration takes the transactions happening in Engine and gets them into your books accurately, without your team re-entering anything by hand.
- Automate transaction flow: your invoices, refunds, vendor bills, and other activity sync into your accounting platform on their own.
- Preserve data quality: account and custom field mappings, vendor references, and expense syncing stay consistent every time, so nothing gets entered inconsistently between systems.
- Improve timeliness: your books reflect what's happening in Engine faster, since you're not waiting on someone to key it in.
- Support reconciliation: every synced transaction is easy to trace back to its source in Engine.
- Reduce operational risk: less manual entry and fewer spreadsheet workarounds means fewer chances for errors to creep in.
Treat the integration as part of your embedded finance stack, not just a technical connector. Chart of accounts design, approval workflows, reconciliation rules, and exception handling matter as much as APIs and file transfers.
Setting up your integration
When you turn the integration on, you'll configure a handful of settings. Getting these right from the start means less cleanup later.
Data scope
- Which transactions are in scope
- Which fields are required for posting
- Whether the integration sends detail or summary data
Posting logic
- Chart of accounts mapping
- Entity, department, class, location, or project dimensions
Data consistency
- Customer, vendor, item, and tax code references
- Currency and exchange rate handling
- Rules for creating or matching records
Operational controls
- Error handling and retries
- Duplicate detection
- Reconciliation and close support
Frequently asked questions
Should I sync detailed transactions?
Engine's integration syncs detailed transactions, which give more traceability and operational visibility. This allows Engine's integration to fit seamlessly into your existing approval workflows and accounting system set up.
Is real-time synchronization always better?
No. Real-time movement helps some workflows, but finance processes usually depend more on accuracy, completeness, and controlled cutoff timing than on speed alone. Many successful accounting integrations run on scheduled intervals instead.
What is the most common reason accounting integrations fail?
The connection itself is rarely the problem. Missing mappings, poor master data quality, undefined exception handling, and weak reconciliation processes cause more issues than the transport method.
Who should approve changes to an accounting integration?
Changes that affect posting logic, mappings, tax treatment, dimensions, or timing should go through the finance owner, with implementation support from the relevant system and technical owners.
