What Our Users Say
Been searching for something like this for months. Our Shopify store processes 500+ orders monthly and this handles everything perfectly. Date formats, tax columns, refunds - all correct.
works good, wish it had batch mode
I was spending 4-5 hours every month reformatting exports manually. This tool paid for itself in the first use. The preview feature helped me verify the mapping before paying.
exactly what i needed thx!!
Super straightforward. Upload, convert, download. No account needed which is nice. Would give 5 stars if they add Xero support.
saved me hours of work
My accountant was so happy when I sent her the converted file. No more back-and-forth about date formats or missing columns. Everything imported correctly on first try.
fast and easy 10/10 would recommend
Been using this for 6 months for monthly reconciliations. Handles all the edge cases - partial refunds, multi-line orders, currency conversions. Very reliable tool.
Good tool, does what it says. Interface could be bit better but conversion quality is excellent. Using it for my 3 Shopify stores.
Switched from A2X to this. Way simpler for my needs - I don't need real-time sync, just clean data once a month. This delivers exactly that.
finally!! something that works with QB desktop!!

Quick Answers
Which QuickBooks Desktop versions are supported?
Pro, Premier, and Enterprise editions from 2020 to 2025. IIF format is supported in all Desktop versions.
What accounts do I need to create first?
All accounts in the IIF must exist in your Chart of Accounts before import. Create: deposit account, sales income, tips income, and sales tax payable.
What data transfers from Square to QuickBooks Desktop?
Sales data, fees, taxes, tips, and discounts transfer daily. Data is summarized into a single daily invoice for easy bank reconciliation.
The Desktop Gap
No Native Square-Desktop Integration
Square doesn't offer a direct QuickBooks Desktop integration.
Most accounting apps (A2X, Synder) only support QuickBooks Online.
Desktop users are left with manual data entry or expensive middleware.
IIF: The Desktop Import Format
QuickBooks Desktop accepts IIF (Intuit Interchange Format) files.
IIF is a tab-delimited format with specific headers (TRNS, SPL, ENDTRNS).
We convert your Square transactions to valid IIF files that Desktop accepts.
Your Data is Safe
Bank-Level Security
256-bit SSL encryption. Same standards as major financial institutions.
No Data Storage
Files are processed directly in browser. No calls to our servers.
GDPR Compliant
Full EU data protection compliance. Your privacy rights protected.

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.
Pro, Premier, and Enterprise editions from 2020 to 2025. IIF format is supported in all Desktop versions.
Yes. QuickBooks Desktop requires admin login and single-user mode for IIF imports.
All accounts in the IIF must exist in your Chart of Accounts before import. Create: deposit account, sales income, tips income, and sales tax payable.
QuickBooks Desktop limits customer names to 41 characters (vs 100 in Online). Names are automatically shortened to fit.
Yes, but be careful of duplicates. Each transaction gets a unique reference number (SQ-xxx) to help identify duplicates.
Check that all account names exist in your Chart of Accounts. Account names must match exactly. QuickBooks Desktop is case-sensitive.
Sales data, fees, taxes, tips, and discounts transfer daily. Data is summarized into a single daily invoice for easy bank reconciliation.
Yes, always backup before importing IIF files. Go to File → Back Up Company → Create Local Backup. IIF imports cannot be easily undone.
