APS

APS specializes in cloud computing, web-based applications, false alarm billing and permit management systems. In practice that means handling plans, proration, dunning and revenue recognition for recurring revenue.

The natural audience is SaaS and subscription companies. Alongside the main category they mention Billing and Cloud Computing. As a very small product team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

APS is based in Pleasant Hill, California and founded in 2011. More on alarmprogramsystems.com.

Before you commit, look at payment processor support, tax handling, and migration help. Get the renewal terms in writing before the first invoice.

If you have worked with APS, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
