For an Indian D2C brand, cash on delivery is often a large share of orders, and many COD parcels come back unopened. Each return to origin costs two shipping legs and ties up stock. The fix most stores use is a confirmation call before dispatch, which means someone on the phone all day.
After dispatch come the "where is my order" messages on WhatsApp and Instagram, almost all answerable from the courier tracking page. Then the money: Razorpay settles in batches, net of fees and GST on those fees, so matching a settlement to the orders inside it and to the bank credit takes a spreadsheet and an afternoon. Stock counts drift when the same product sells on the website, a marketplace and in a physical store.
These are the jobs e-commerce automation handles well. They are frequent, rule-based and checkable. Pricing, buying, product decisions and customer complaints that need judgement stay with your team.
