This post is part of a series covering the billing tech startup landscape. You can view the full interactive map with more than 20 startups here.

The mapping above covers the new generation of billing tech for B2B software. The goal is to illustrate see how this market is evolving, compare the different approaches adopted by founders and discover the players shaping the future of software pricing.

Full Stack Billing Platforms

What is the scope of core billing platforms?

These platforms manage the full revenue cycle for software companies:

Subscription lifecycles: Create plans, manage upgrades or downgrades, control renewals and deal with cancellations.
Invoicing and payments automation: Generate invoices, collect payments, manage taxes and support multiple currencies.
Usage metering: Ingest raw product events, validate them, enrich them and aggregate them into a clean usage stream that billing and pricing systems can rely on.
Unify pricing models: Support flat subscriptions, seat based pricing, usage add ons and hybrid models in one system.
Customer accounts management: Track contracts, balances, credits and customer history across billing periods.
Finance and CRM systems integration: Sync with ERPs, accounting software and CRM tools to close the loop between sales, billing and finance.
Revenue workflows: Support revenue recognition, dunning, collections and audit trails needed for compliance.

Why did a new generation of full stack billing platforms emerge in the past couple of years?

Developers want systems they can actually integrate: The move toward API first and developer friendly software opened space for open source and engineering centric billing platforms.
The shift to hybrid pricing created new needs: SaaS companies now mix subscriptions, seats, credits and usage, which exposed limits in older billing systems.
Modern products generate richer billing events: AI and API based businesses need flexible pricing infrastructure that can evolve fast, pushing founders to build new solutions.
Finance teams want cleaner workflows: Traditional tools often require spreadsheets and manual steps. New entrants promise automation and a smoother quote to cash path.
