Our pricing unit counts are the number of common model instances synced by Merge across all live (i.e., production) Linked Accounts!
We only count common model units from live (i.e., production) accounts. We do not charge for test accounts. To avoid incurring any unwanted charges, please make sure to mark your test accounts as such. You can view instructions on marking test accounts in our Help Center here.
You can access your pricing unit counts on the top right of your Billing page!
