Two rates, two questions
Logo renewal rate is the number of customers who renewed divided by the number due to renew in the period. Revenue renewal rate is the recurring revenue renewed divided by the recurring revenue up for renewal. Neither is sufficient alone. A business can renew nine of ten customers and lose half its revenue if the tenth was large, and the reverse is equally possible.
The date that matters
Most agreements carry a notice period, and the notice deadline rather than the end date is the point at which the decision becomes irreversible. Recording both, and scheduling all renewal work backwards from the earlier of the two, is the single most useful structural change most teams can make to their renewal process.
A worked timeline (illustrative)
Take an annual contract ending on 31 December with a sixty-day notice period. The notice deadline is 1 November, so that is the date everything works back from. Late July: an internal review covering usage, support history, outcomes delivered and any change in stakeholders. August: a value conversation with the customer, which is also where problems surface while there is time to address them. September: issues raised are worked, with owners and dates. Early October: the renewal proposal, including any uplift and any expansion, presented as one package. Late October: agreement, or escalation, ahead of the notice deadline. November and December: paperwork. Nothing important happens in the last month, which is the defining property of a renewal process that works.
