SharePoint app customization is possible by dedicated app version installed from SharePoint App Catalog (here is more info.)
Customized app version is new app instance, not an update performed on app instance downloaded from the SharePoint Store.
Total customization cost = app license cost (only if you don't have it yet) + 300 USD of initial setup fee (one-time fee,only first customization) + cost of implementing changes (one-time fee) + monthly support fee (depending on number of users).
The cost of implementing changes is based on the level of complexity and estimated working hours, typically ranging from a few hundred USD for very small modifications (e.g. changes in labels) to several thousand USD or more for more significant modifications.
To get an detailed estimate for your customization, send us email with application name and scope of changes, for example:
App Name: Service Desk Pr
Customization scope:
1. Add new button on the request creation form that perform specific operation
