Remind customers before they are charged
Send a reminder a month and a week before renewal that states the date, the amount and how to change or cancel. Surprise charges become chargebacks.
Prepare the replies you will need
Write answers for price questions, invoice requests, seat changes and cancellation, and load them as macros.
Be clear about refunds
State your policy for a renewal the customer did not expect. A clear rule is easier to apply fairly.
Spot at-risk accounts early
Tag tickets from accounts renewing soon and check them. Unresolved problems before a renewal are the best predictor of a cancellation.
Follow up after the renewal
Thank customers who renewed and ask those who left why. Both answers improve the next cycle.
