No you do not need an external system for contacts/tendering unless you are tendering to an external system, which in your case you are not. As far as your problem goes, check and make sure that your service provider and dispatch locations have the same Corporation ID... this is how they are linked for tendering.

I know I've seen this problem before when OTM tenders out 24 hours instead of the time you specified but I can't remember why right now. If you read your logs after tendering it should pop out at you. Are you sure the e-mail tenders are going out correctly? Sorry I can't help more, but I remember that this has something to do with OTM not being able to find something during the tendering process so it defaults to 24 hours for response time. It may have something to do with the logistics involved party on your shipment. If I remember I will post again and let you know. Good luck!
