I offer a monthly maintenance plan that includes 2.5 hours of support per month for 12 months at a reduced rate. The support plan is paid in advance. I have also offered custom plans for 6 months of support for clients who have asked.
The plan includes upgrades, theme customizations, plugin recommendations and installation, general questions, etc.
Another feature of the support plan is being moved up the support request list. A client on a support plan is going to be responded too quickly and the work will have a higher priority than other types of requests.
Ok – so why am I talking about this now? Well, I have recently been asked about offering smaller plans. For example, many people may only need 1 hour of support per month rather than 2.5 and I don’t have any support plans that cover that.
