Hi there Dlmm324,
Thanks for reaching out about your client's reconciliations. QuickBooks Online Accountant is a great tool able to assist in helping you connect with all your clients' books from one platform. I can provide some information about removing a reconciliation.
You can undo the reconciles all the way up to the wanted date by following the steps in this article if you're accessing your client's books from your QuickBooks Online Accountant platform. Once undone, you can redo the reconciliation for those months so that the ending dates will be correct.
Also, please do make sure that you're only using the methods provided by a trusted source for reaching out to the support team outside of the Community. Trust only the information provided by a member of the Community that has the QuickBooks Team badge, like myself, or a Moderator badge in the same place.
If you have any other questions, feel free to reach out here.
