Flux tax rates let you define the rates you charge and apply them automatically to invoices and checkout. Tax shows as its own line for the customer, and it stays itemized through reporting and the QuickBooks sync so filing time is not a spreadsheet hunt.
Why businesses use it
Applied automatically
Attach a rate once and every invoice or checkout applies it without manual math.
Itemized for the customer
Tax appears as its own clear line, not buried in the total.
Ready for filing
Tax stays itemized through reports and QuickBooks, so totals are there when you file.
How it works
Create the tax rates you charge in the dashboard, then attach them to invoices, payment links, or checkout. Flux calculates the tax on each payment, shows it as a line item, and keeps it itemized in your reporting.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume merchants and no setup fees or contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee. You can also pass the processing fee to the customer at checkout where local surcharging rules allow.
