Offering customers a variety of ways to pay for your product allows for flexibility and ease. In general, there are two ways for customers to pay for usage: Post-paid and pre-paid. Pre-paid is sometimes also referred to as PAYG, or Pay-As-You-Go. Post-paid usage can sometimes lead customers to have billing surprises if they are not tracking their usage closely. This can cause headaches for these users and can also cause issues for the service provider.

Many API developers and companies struggle to find ways to easily set up systems to monetize their APIs. Some are simple but not customizable, some are complex and require massive engineering effort to actually get it all running. To make things easier, Moesif created a feature a few months ago called Billing Meters which gives massive customizability but with a minimal amount of code and engineering effort.
