Trusted by businesses selling across borders
Square takes the payment. Tax compliance is still on you
Rebuilding invoices, tax reports, and threshold checks from Square exports costs hours every month and leaves gaps an audit will find.
Square on its own
- Invoices by hand Making every invoice and credit note compliant for each country yourself.
- Spreadsheet tax reports Exporting Square data and rebuilding VAT, GST, and sales tax totals before every filing.
- Missed thresholds Finding out you crossed a nexus or VAT threshold after the back taxes have piled up.
