VatPay

VatPay provides software for online invoicing, time tracking, project management, and automated billing. The job it does: handling plans, proration, dunning and revenue recognition for recurring revenue.

The natural audience is SaaS and subscription companies. They also list Billing and Project Management, so expect those to show up in the feature set. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

VatPay is based in Atlanta, Georgia and founded in 2010. You can read more at vatpay.com.

Before you commit, look at payment processor support, tax handling, and migration help. A short pilot with your real data tells you more than any demo.
