I handle bookkeeping for a small restaurant group with four Square POS locations. The Square Xero integration through CSV lets me review each location's transactions separately before importing, which the native sync doesn't support. Month-end close went from two days to half a day.

How People Use This
Our coffee shop runs everything through Square but our accountant uses Xero. I tried the built-in Square Xero connector but it couldn't pull historical data from before we set it up. The CSV-based approach let me integrate six months of backlog in one batch.
Several of my clients use Square POS and need their sales data in Xero. Each client has different GL mapping requirements. The file-based integration gives me control over how transactions land in their chart of accounts, something the automatic sync tools don't allow.
Integration Questions Answered
How does this compare to Square's native Xero integration?
This CSV-based approach offers more control: historical data import, custom GL mapping, offline processing, and no monthly fees. The native integration is simpler but less flexible.
What Square data can I integrate?
Transactions (to bank statements or invoices), customers (to contacts), and item catalog (to inventory). Use our specific tools for each data type.
Is this a one-time setup or ongoing?
Ongoing — export from Square periodically (daily/weekly/monthly) and import to Xero. The frequency depends on your reconciliation needs.
The Square-Xero Integration Challenge
Why Native Integration Falls Short
Square's built-in Xero integration has limitations: no historical data import,
limited control over GL account mapping, doesn't handle complex multi-location setups,
and no offline capability. When you need to import Square data into Xero with full control, CSV-based integration is the better approach.
Our Integration Approach
This tool provides flexible Square-Xero integration:
Export data from Square (transactions, customers), convert to Xero-compatible CSV format,
and import directly into Xero. Works offline, handles any data volume, and you control
the timing. Supports bank statement mode, invoice mode, and contact sync.
Seamless and Secure Integration
Automatic Column Matching
Fields from your source file are mapped to the right columns in the target format. No manual work needed.
Runs in Your Browser
Integration runs entirely in your browser. No third-party access to your data.
GDPR Compliant
No data leaves your machine. Full EU privacy compliance.

Common Bank Statement Import Errors
Issues you might encounter when importing Transactions Export data to Bank Statement - and how we solve them
Cash Transactions in Clearing
Cash doesn't flow through Square to bank
Enable 'Exclude cash transactions' option
Cash should go to separate Cash on Hand account
Fees Have Wrong Sign
Square exports fees as negative, Xero needs negative for outflows
We preserve the negative sign automatically
Check that fee rows show negative amounts
Transaction vs Deposit Date
Bank shows deposit on different day than transaction
This is normal - Square batches daily, deposits next day
Match by Deposit ID or batch deposits together
Gift Card Recorded as Revenue
Gift card sales are liability, not revenue
Enable gift card detection for proper handling
Post to Gift Card Liability account, not Sales
Frequently Asked Questions
Your data never leaves your device. All files are processed entirely in your browser using client-side JavaScript - no data is stored on our servers or sent anywhere. There's no account to hack, no database storing your files, and no API connections to your bank or accounting software. You upload, convert, download, and we forget it immediately.
No payment or signup required. You can upload your file, see a free preview of the conversion results, and verify everything looks correct before paying anything. If it doesn't work for your files, you haven't wasted any money. We only charge when you're satisfied and ready to download the final converted file.
You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.
This CSV-based approach offers more control: historical data import, custom GL mapping, offline processing, and no monthly fees. The native integration is simpler but less flexible.
This tool is for manual/batch integration. For real-time automation, you'd need Square's native integration or a third-party app. Many businesses prefer monthly batch processing for better control.
Transactions (to bank statements or invoices), customers (to contacts), and item catalog (to inventory). Use our specific tools for each data type.
Ongoing — export from Square periodically (daily/weekly/monthly) and import to Xero. The frequency depends on your reconciliation needs.
Export your transaction report from Square Dashboard, upload it to our converter, then import the bank statement CSV into Xero. No API connection or third-party subscription needed.
Disable your bank feed for Square deposits or use only the Square integration to avoid duplicates. Reconciliation becomes simpler when transactions come from one source.
Most integrations support syncing transactions from the past 30-90 days. Older data may require manual import or special configuration depending on your integration method.
Yes, the integration supports multiple Square locations and can organize sales by store with proper chart of accounts mapping in Xero.
Tips are typically synced as separate line items or added to sales transactions. You can configure how they map to your Xero accounts during setup.
You need to manually map Square categories to Xero accounts during integration setup. Custom account mapping ensures accurate expense categorization.
Most integrations sync data within 1-24 hours. Real-time syncing may vary based on your integration provider and Xero's update frequency.
