Plastiq is billpay with benefits.

Everyday payments have become second nature: we swipe a card, tap a button, or press submit. But many of our most important bills — a child's care or tuition, critical business expenses, or taxes and rent — haven't caught up. Billions of checks are still written today. Wire transfers can be confusing. Payments are slow, late, or even unaccounted for.

We set out to pursue these challenges.

Our mission? To make bill payment simple and seamless. Plastiq lets you pay bills in the way that works best for you. We hope you love the service. 

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
