Abstract
Using the next-to-leading order (NLO) coefficient functions for exclusive electroproduction of heavy vector mesons derived in our previous work, we perform various phenomenological studies of exclusive electroproduction in ep collisions relevant for both the existing measurements from HERA, and the forthcoming Electron-Ion Collider (EIC). We compare our cross-section results to HERA data across a broad range of photon virtualities 
and 
centre-of-mass energies, provide predictions for upcoming EIC measurements and conclude with a discussion on the necessity of resumming logarithmically enhanced contributions in 
electroproduction.
