Pros
Billtrust cares about their employees and about their customers. At the end of the day that's what matters most. How do they show they care about their employees? They higher the best. They offer open PTO. They try to keep healthcare costs low. They offer a mentor program and an Employee Resource Group program. They do weekly virtual trivia. They offer pathways for growth. And your coworkers are willing to answer your questions, show you what they do, and help you when they can. How do they show they care about their customers? It's embedded in the strategic imperatives. It's at the core of how they approach problems. It's about how everything from pricing to features is centered around finding wins for the customers which are then wins for the company. Also - the company values. If you haven't yet gone to the website and looked at the values please do. It's not just words on a website it's legit. And if the values resonate with you then you will fit right in.
Cons
Take a look at the size of the company and make sure this is for you. If you thrive at a very process driven organization of hundreds of thousands you might want to wait and check back in here in five years. If you like 3 person start ups this also might not be for you. (Though it depends on the department what the energy is like.) If you want to join a quickly growing company which is big enough to have resources for employees and room to grow and learn but small enough that every day is an adventure then this is for you. Also - I hesitate to say anything about offices / work from home since the world changes daily. But as of the writing of this review I work from home and have the option to do that indefinitely but also have the option to work from the headquarters which is close to where I live. For me, it's great to have those choices.
