I have been using Expedia Corporate Travel / Egencia for about 6 months and have never had an issue with points posting or getting upgrades. BUT, I always use the "PUBLISHED RATES" not the "EXPEDIA SPECIAL RATES" (visable when clicking the "View all rates" link on the hotel map/search page). Before I used travelport.net and about 1/4 of my stays would not show up because my HH number was not in the reservation, but filling out the form on hhonors.com would always get the points posted within a few days. Also, if I caught it at check-in, the front desk person would enter my number and then the credit would work fine.
