ParcelWILL Order Tracking

Function wise it's pretty good.
Frustratingly they are quick to remind you to upgrade when you reach the limits of a plan, but they don't automatically reduce the amount you pay if your orders that month fall short of the tier you're in. Looking back at the past few months I can see that we've lined the pockets of Parcel Panel with $100s of unused credits because they told us we needed to upgrade the plan when really we didn't.

Update: since writing my original review, the PP team reached out to refund about 1/4 of the over payments I made this year (paying for tiers that I wasn't using). They have also created a bespoke plan for me which has made the whole PP experience a lot more cost effective.
