Overview

Regular subscriptions allow you to periodically bill your customers for provided services at any arbitrary schedule.

Prepaid models allow your customers to buy a certain amount of billable metrics units and use them until running out of balance.

A good example is, your customers buy 1000 credits, use them and top up as needed.

Another example is a Trial plan with 500 API calls included. Once the customer makes 500 requests, Nadles revokes access.

Nadles API gateway and billing engine work together to track usage per subscription, periodically aggregate the usage data, calculate and bill amounts due.

You can combine several prices with different billing intervals in a single subscription.

It’s easier to illustrate with an example. Let’s say, you would like to offer an annual plan with overages paid monthly.

E.g.,

• $400 a year
• 5000 API calls per month included
• $0.1 overage, billed monthly

With Nadles, implementing this kind of pricing can be done with several mouse clicks.

Sometimes you’d like to record usage more often and collect a payment once in a while. You can do so by setting different billing and usage aggregation periods.

For example, you can configure Nadles to aggregate usage daily and bill for the accrued amount once a month.

By combining different kinds of pricing and billing rules you can create complex pricing scenarios that fit your business model.
