Subscription for the product is on a monthly basis with no long term contracts.
Users are charged fixed monthly amounts for a 30 day period based on a specified number of trial balance imports.
The software locks out the user at the earlier of the expiration of the 30 day period or usage of all the imports credits for the month.
User will therefore have full use of all the feature of the application and pay for only actual usage.
You can also choose to buy subscriptions for any number of months in advance.
