Notes From the Field

In fulfillment, mistakes are rarely random. The same type of order causes the same type of problem in the same way. There are 5 order types that keep coming up on the floor, again and again:

The 5 Order Types That Cause the Most Mistakes

1. Multi-variant orders — Different size/color combinations of the same product leave the door open to picking the wrong variant.
2. Campaign-period orders with gift/promotional add-ons — If the add-on product logic isn't set up correctly, the risk of shipping too little or too much increases.
3. Orders with missing or unclear address information — Addresses missing apartment/block details in particular lead to delivery delays.
4. Repeat orders involving partial returns — If stock synchronization isn't handled correctly, the same mistake repeats.
5. High-volume single-customer orders (bulk purchases) — Large orders that fall outside the standard packaging process require extra checks.

How to Reduce the Error Rate

The problem usually isn't the order itself; it's how we process it. Identifying these 5 types in advance and building integrated checkpoints into the system significantly reduces the error rate.
