The AI-native billing platform

About us

The AI-native billing platform

Every company needs billing. Lago is open-source and gives you the flexibility of a homegrown system with the features of an enterprise-grade vendor.

Billing shouldn't suck

Getting paid should be the easy part. But billing systems make it hard. For the longest time, you had to buy a third-party black box or waste time constructing your own billing. Lago fixes that.

It's not a problem that goes viral on social media, but it's ubiquitous in tech companies.

At one of Europe's biggest fintechs, we saw the “billing nightmare”: 10+ full-time engineers worked on billing alone. Product grew frustrated because pricing took months. Finance labored in spreadsheets they shouldn't need.

Nobody talked about this common issue: Bad billing systems block projects, frustrate teams and devour resources better spent on innovation.

But what options are there? Building your own system is a nightmare. Third-party systems become black boxes that cause more work than they save.

We wanted to solve billing, and open-source became the obvious choice. You should have full transparency and control your financial infrastructure without sacrificing the feature set of a market-leading vendor. That's how Lago was born.

Millions of invoices later, we're happy to support emerging and established leaders on billing so they can focus on building, not billing.
