Should you Build or Buy the Billing System?

Building home-grown billing systems is a good idea until a two-month sprint becomes a full-blown one involving at least 10 engineers and extending way beyond 12 months.

Most organizations start with “just-good-enough” billing systems that works well enough—up to the point your business starts to scale up.

As you acquire more customers and start integrating with more tools and databases, not to mention experimenting with flexible pricing strategies, your billing workflows only get more and more complex.

This is why we find many businesses at a crossroads where they have to decide between continuing to build an in-house billing system or switching to a vendor with an off-the-shelf solution.

We’re putting an end to this dilemma…
