Seasonal Capacity: Paying for Your Peak Only in the Peak

The people-shaped ones. User licences, phone system seats, mobile lines and SIP call channels can be added for a period and removed afterwards. Circuits cannot — a leased line or fibre install is committed for its term regardless of trade. So the flexible saving is in licensing and capacity, not in the connection itself.

The peak, without much hesitation. A connection that copes in February and fails in December is not a saving, it is a failure deferred to the month you can least afford it. Connectivity is also the item you cannot change quickly, so under-sizing it leaves you with no route out during the season itself.

A season ahead rather than at the start of one. Adding licences for December in November is straightforward; doing it on the second of December, when the temporary staff are already in, is where it goes wrong. It is worth putting the dates in a calendar with the rest of the seasonal planning rather than treating it as reactive.

From what actually happened last season rather than what people remember, because memory overstates the peak every time. Call reporting shows the busiest hour of the busiest day, which is the number that matters, and it is usually lower than the estimate — meaning the flexible uplift needed is smaller and cheaper than expected.

You generally have to ask, and that is the honest answer. The default at renewal is to reissue what you had last year, so a business that grew a seasonal team three years ago is still paying for it in the off-season unless somebody raises it. It is one of the more common findings in a bill review.

Then this probably is not for you, and we would say so. Flexing capacity has an administrative cost and it only pays where there is a genuine off-season — a real trough of months rather than quiet weeks. For a business with steady volume that merely feels busy at times, the right answer is sizing correctly once.
