Ecommerce Order Fulfillment in India: When to Pack In-House and When to Use a 3PL

Ecommerce fulfillment is more than courier pickup. It includes receiving inventory, storage, order capture, picking, packing, shipping, tracking and returns. When volume is small, doing this in-house can make sense. As channels, SKUs and orders grow, fulfillment can become a constraint.In-house or 3PL?Do not outsource only because packing is tiring, and do not stay in-house only because a 3PL quote looks expensive. Compare total cost and service performance.FactorIn-house3PLControlHighDepends on SLAFixed costOften higherOften more variablePeak scalingYou add capacityPartner may absorb peaksMulti-city stockCapital intensiveOften easierCalculate real in-house costInclude space, fulfillment salaries, supervision, software, equipment, inventory shrinkage, picking errors, carrier coordination and returns handling.Assume a brand ships 2,000 orders per month. Space and utilities cost ₹70,000, the fulfillment team ₹1,20,000, software and equipment ₹20,000, and operational errors ₹20,000. That is ₹2,30,000 before shipping and packaging materials, or ₹115 per fulfilled order.If volume falls to 1,200 orders while most costs stay fixed, overhead becomes about ₹192 per order. This is why variable 3PL pricing can be attractive for volatile brands.Metrics to trackOrder accuracy: correctly shipped orders divided by total shipped orders.Dispatch time: order confirmation to carrier handoff.Inventory accuracy: system stock compared with physical stock.RTO rate: track by channel, pincode, product and courier.Cost per successful delivery: total fulfillment and logistics cost divided by successfully delivered orders.When a 3PL deserves a pilotPeak sales overwhelm your team.You need stock in more than one city.Marketplace and website inventory goes out of sync.Warehouse labour management is becoming a separate business.Cost per successful delivery keeps rising.Run a controlled 3PL testChoose representative SKUs.Send a limited quantity of inventory.Route one channel or region through the partner.Run the pilot for four weeks.Compare accuracy, dispatch time, cost and returns.Reconcile physical and system inventory before expanding.Mistakes to avoidChoosing only on pick-and-pack price.Ignoring return processing fees.Moving without a clean SKU master.Splitting stock across too many locations too early.Signing a long contract before testing performance.SourcesShopify India, 3PL in Ecommerce, 2026Shiprocket Fulfillment, ecommerce order fulfillment
