About KoPay

Built in the USA. Built on feedback.

KoPay is invoicing software built specifically for service businesses — contractors, tradespeople, field technicians, and small business owners who send invoices and collect payments as a core part of what they do.

We're a US-based team, and we take user feedback seriously. When a contractor tells us something is broken or missing, we fix it. When a locksmith tells us they need to invoice faster from the field, we build for that. The features in KoPay exist because real businesses told us they needed them.

The processing fee pass-through feature — our most-used and most-loved — came directly from contractors who were tired of watching 3% disappear off every card payment. It's now baked into the core of the product and available to every business type we serve.

KoPay is currently free during our early access beta. We'll announce paid plans well in advance and give early users priority access to any launch pricing. There are no surprises.

If you're a service business that invoices customers, collects card payments, and has ever wondered why your invoicing software doesn't handle fees properly — KoPay was built for you.

100% US-based team building for US service businesses
Free During beta — unlimited invoices, estimates, and customers
Stripe Powered — PCI Level 1 certified payment processing under the hood
