If you’ve attached a Product Plan to an end-customer Account and the Plan is priced using a _Counter_ for unit-based recurring subscription charges, you can then use the _Counter Adjustments_ tab on the Account page to create adjustments for the number of Counter units the Account subscribes to. The Counter Adjustments on an Account for a given billing period will then determine the recurring charges calculated for that period’s Bill. For full details on how to work in the Counter Adjustments tab to create and manage Counter Adjustments for your end-customer Accounts, please see the [Understanding and Creating Counter Adjustments for Accounts](https://docs.m3ter.com/guides/recurring-charges-counters/creating-counter-adjustments-for-accounts) topic in the [Recurring Charges](https://docs.m3ter.com/guides/recurring-charges-counters) section.

**Important!** Before you attempt to price your Product Plans for unit-based pricing, attach those Plans to Accounts, and then create Counter Adjustments for Accounts, we _strongly recommend_ that you review all of the topics in the [Recurring Charges](https://docs.m3ter.com/guides/recurring-charges-counters) section, which explains how to work with Counters for pricing Plans and manage Counter Adjustments on Accounts for recurring charges billing.
