The cost of a managed file transfer (MFT) solution depends on factors such as
Cloud or on-premises
The number of file transfers
The number of endpoints
The complexity of file processing, e.g. transformation from one file to another location.
Migration from legacy systems to a new system
Custom integration with APIs
On-premises managed file transfer costs may be based on how many servers, endpoints, MFT agents or domains you have. Some on-premises MFT solutions now offer a subscription model.
Cloud managed file transfer costs may be based on usage, feature bundles, interfaces or endpoints—it depends on the vendor and what you can negotiate.
The bottom line: Because it is difficult to say an exact number here, keep the cost question top of mind as you talk with vendors. Make sure you understand their pricing model and how it compares to others.
