I use Wave for accounting because it's free, but there's no direct Square integration. I export my Square POS transactions weekly and convert them to Wave bank format with fee split mode enabled. Having the processing fees as separate expense rows makes my tax deductions accurate without manual journal entries.

How People Use Square → Wave
Several of my small business clients use both Square and Wave. I convert their Square transaction reports to Wave's bank import format monthly. The location tracking in descriptions helps me categorize income by store when clients have multiple Square locations.
I process all card payments through Square and do my books in Wave Accounting. The converter handles my refunds as negative amounts correctly, so my Wave income reflects the actual revenue. I run it every two weeks and import to a Square Clearing account to avoid duplicates with my bank feed.
Square → Wave Conversion Questions
Should I use fee split mode?
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.
How do I get the Square Transaction Report CSV?
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.
Does Wave directly integrate with Square?
No. Wave doesn't offer native integration with Square. Our converter bridges this gap by transforming your Square transaction CSV into Wave's bank import format, with no subscription required. Just export from Square, convert, and import to Wave.
Why Convert Square to Wave?
Track Square POS Income
Square is widely used for retail POS, online payments, and mobile card processing. Wave needs proper tracking but lacks direct Square integration for all accounts.
This tool converts Square's Transaction Report CSV to Wave bank format:
- Track all Square sales and refunds
- Separate fees for tax deductions
- Reconcile payouts with bank deposits
Fee Tracking Options
Two modes for handling Square fees:
Net Mode (default): Uses net total after fees. One row per transaction.
Fee Split Mode: Two rows per transaction - total collected + separate fee expense for detailed tracking and tax deductions.

Frequently Asked Questions
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. Our converter bridges this gap by transforming your Square transaction CSV into Wave's bank import format, with no subscription required. Just export from Square, convert, and import to Wave.
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.
