Hi @Vistaro
Accounts are automatically upgraded to a Power User Subscription once they are over a 1000 nominal entries in a rolling 12 month period. It sounds as though you have gone over this threshold while entering the old data.
The £45 (+VAT) is chargeable on an annual basis for the Power User Subscription. If your account drops to below the 1000 nominal entries in the rolling 12 month period then the renewal of the Power User Subscription is optional.
If you feel as though an Affinity Account is more suited to your needs, you can find out more information about it here: https://www.quickfile.co.uk/home/affinitypricing
However, please note that this will be charged on a monthly basis rather than annual.
If you are using an Affinity Account, you will not need to pay for the additional Power User Subscription. However, there are different features enabled for the different account types so please be aware that some features may be different. For more information on the differences between the Power User Subscription and Affinity Account, please check out the following: Power User Subscription vs Affinity
I hope this helps, but if you have any further questions, please don’t hesitate to ask.
