Why Convert Square to Wave?

Track Square POS Income

Square is widely used for retail POS, online payments, and mobile card processing. Wave Accounting requires proper transaction tracking but doesn't have direct Square integration for all account types. This tool converts Square's Transaction Report CSV into Wave's bank transaction format, allowing you to: - Track all Square sales and refunds in Wave - Separate Square fees for tax deductions - Reconcile Square payouts with bank deposits - Maintain accurate retail business bookkeeping

Fee Tracking Options

Square charges processing fees on all transactions. This tool offers two modes: Net Mode (default): Uses the net total (after fees). Simple and clean - one row per transaction. Fee Split Mode: Creates two rows per transaction - total collected + separate fee expense. This gives you detailed fee tracking for tax deductions and profitability analysis. Most retailers prefer fee split mode for accurate expense categorization in Wave.

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.
Yes, if you want to track Square fees separately as business expenses for tax deductions. Fee split mode creates two rows per transaction: the total collected from customers and the fee expense. This matches real-world accounting where fees are legitimate business expenses. Use net mode only if you prefer simple one-row-per-transaction tracking.
Log into Square Dashboard → Transactions → Click 'Export' → Select date range → Choose 'All columns' → Download CSV. You can export up to 90 days at a time. For longer history, export multiple date ranges.
Square deposits to your bank will appear in both Square export and bank feed. Import Square transactions to a 'Square Clearing' account in Wave, then record deposits as transfers between Square and Bank accounts to avoid duplication.
Refunds appear in the Square export with negative Total Collected amounts. The converter preserves this negative sign, so refunds appear as negative (withdrawals) in Wave. This correctly reduces your Square income.
Square includes tips in the Total Collected amount. If you need to track tips separately, you'll need to categorize them manually in Wave after import, or use Square's itemized report and process differently.
Yes! Enable 'Include Location in Description' to add location names to each transaction. This allows you to filter or categorize by location in Wave after import.
No. Wave doesn't offer native integration with Square, so you'll need to export CSV files from Square or use automation tools like Zapier to transfer data.
Bank deposits show net amounts after Square's processing fees are deducted. You need to 'gross up' sales by recording the fees separately to match your actual revenue.
Use MM/DD/YYYY format for Wave imports. Dates must have leading zeros (01 not 1) and cannot be in the future, or the upload will fail.
Yes. Bank imports show net deposits (after fees), while CSV imports show gross sales. Using both together will create duplicate records with different amounts.
