The job description online doesn't give the "full picture". This is actually a very entry level basic job with high volume sourcing, data entry, project tracking, and basic office skills. This is not marketing - not account management - much closer to a/r and administrative support of sales reps.
The sales reps get the business and say YES then turn it over to this role to source a vendor, craft a proposal, and ensure everything happens in the time frame the sales rep promises.
