Choose a comparison period and expected call volume. For each offer, add its one-off implementation costs, recurring charges for that period, expected usage charges and the cost of retained staff review. Add any overlapping services, contract exit costs and ongoing integration work. Count a charge once if it is already included in a package.
Comparison total for the agreed period
One-off costs + recurring charges + usage charges + internal review and escalation costs + transition costs.
