Are you a Microsoft Dynamics customer? Are you paying an annual amount for software maintenance? Then you need to be logging in to CustomerSource at least annually to ensure that your annual software maintenance agreement (sometimes referred to as "BRAP") is being renewed with Microsoft.
This is to ensure that your payment is being processed correctly and also keeps your Dynamics Partner in check. I'm not going to comment further other than to say that errors can happen but I'm also a former retailer myself and intentional miss-use of funds paid by a retailer to a Dynamics Partner specifically for software maintenance renewals is not cool or ethical (or legal).
If you require assistance, please contact Microsoft at 888-477-7877.
If you are a Dynamics RMS/HQ, POS 2007, POS 2009, or POS 2.0 user, I may be able to assist you as well - I can be reached at 208-340-5632 or firstname.lastname@example.org.
