Your books should not get a price hike every single year.

Invoicing, expenses, a live bank feed, sales tax, and a P&L written in plain English, for service businesses that will never need inventory, payroll modules, or a four-tier upsell ladder.

$19/month. The price you join at is your price, for life.

The pledge is the product. Published on this page. Written into the terms.

Everyone else is climbing. We signed a pledge not to.

The incumbents keep raising prices 15-25% at a time, and the cheap tiers exist mostly to move you to expensive ones. FlatBooks is one plan with everything, locked at the price you join at.
