Cost of building an inbound call center
The total cost to build an inbound call center can include many elements:
If you're building a new call center that is based on another already existing center, you may not need to do process work. However, if this is a net new function, you will also incur costs for things like planning, sizing, securing vendors and contracts, process design and documentation. Many companies use consultants to help develop a new center as there is much work to do and you won't likely have all the resources you need to do it. So, you might want to include consulting costs to develop the center as well.
We use a sophisticated tool for efforts like this that let you plan out the new center and budget based on the processes you need to handle, the workload they drive, the number of staff that workload demands, the technology and facilities you require for those staff. You should consider such an approach to get an accurate budget for building your center. Two new white papers written by Brian Hinton, a consultant at my firm, will help you learn more about such modeling:
