Hello,
We are looking into using USPS First Class Large Envelopes “Flats” (not a flat rate shipping method, but literally a flat envelope) to ship a majority of our products. We sell small, thin envelopes of seeds. We will save about $100k a year in shipping costs by switching from Ground Advantage to USPS First Class Large Envelopes.
Is anyone using this service method in Acumatica?
I do not see this as an option when setting up a Ship Via. We have an integration with stamps.com and it does exist as a service method on our account:
I wonder if we have to do something similar to when we set up Med/Large Flat Rate ship vias? We had to do some heavy lifting to get those working:
First by creating new Carrier IDs for each of those:
→ then putting those new Carrier IDs in the Ship Via as the “Carrier”
→ Then adding specific BOX IDs to the packages tab of the Ship Via
I wonder if we have to do the same for First Class Large Envelopes? The only wrinkle is that these are NOT flat rates. Depending on envelopes size (we’ll have two different sizes), weight and shipping zone, it is a different charge.
