Why Order Routing Matters
Order routing is the decision: "Which warehouse should fulfil this order, using which carrier, assigned to which ERP entity?"
For a business processing 100 orders/day with 2 warehouses and 5 carrier partners, that's 100 routing decisions per day. Manageable manually. But at 1,000 orders/day? At 10,000? Manual routing becomes a full-time job — and it still produces errors.
Automated order routing makes these decisions in milliseconds, consistently, 24 hours a day.
The Anatomy of an Order Routing Decision
A routing engine evaluates each order against a set of prioritised rules:
Step 1: Inventory check
Does the preferred warehouse have stock? If yes, route there. If not, check alternative warehouses.
Step 2: Delivery zone match
Which warehouses can service this delivery pin code within the required SLA? Filter to eligible warehouses.
Step 3: Carrier selection
For the selected warehouse, which carriers service this pin code? What is the SLA and cost for each? Select optimal carrier based on configured priorities.
Step 4: ERP assignment
Which legal entity (company, subsidiary) should this order be assigned to in the ERP? Based on customer account, delivery location, or order type.
Step 5: Fulfilment instruction
Push the fulfil instruction to the WMS with: warehouse location, carrier, shipping label request, and ERP reference.
All of this happens in under 200 milliseconds per order.
Real-World Routing Rule Examples
Rule 1: Mumbai orders → Navi Mumbai warehouse → Delhivery
Customer pin code in Mumbai city limits → route to Navi Mumbai DC → assign Delhivery as carrier (best SLA in Mumbai)
Rule 2: B2B orders → dedicated B2B warehouse
Order type = B2B → route to B2B fulfilment centre → standard carrier with invoice-based shipping
Rule 3: Low margin orders → economy carrier only
Order value < ₹500 AND SKU margin < 15% → restrict to economy carrier (max ₹50 shipping cost)
Rule 4: Same-day delivery → hyperlocal carrier
Customer opts for same-day delivery → route to nearest warehouse → assign Shadowfax or Dunzo
Rule 5: Out of stock fallback
Primary warehouse = 0 stock → check warehouse 2 → if 0, check warehouse 3 → if all 0, trigger backorder workflow in ERP
The Cost Impact of Intelligent Routing
A B4Ucommerce customer in the electronics space saved ₹18 per order in shipping costs — ₹1.8 Cr per year at 10,000 orders/month — simply by routing orders to the optimal carrier instead of defaulting to a single carrier contract.
Another customer in fashion reduced average delivery time from 4.2 days to 3.1 days by routing to closer warehouses based on customer pin code clustering.

Frequently Asked Questions
What is automated order routing?
Order routing is the decision of which warehouse fulfils an order, with which carrier, assigned to which ERP entity. An automated routing engine makes that decision in under 200 milliseconds per order by checking inventory at the preferred warehouse, matching the delivery pin code and SLA, selecting the optimal carrier on cost and speed, assigning the correct ERP legal entity, and pushing the fulfilment instruction to the WMS.
When does manual order routing stop working?
At 100 orders/day with 2 warehouses it's manageable manually. At 1,000 orders/day it becomes a full-time job that still produces errors, and at 10,000 it's impossible. Automated routing makes the same decisions consistently, 24 hours a day, in milliseconds.
What do real order routing rules look like?
Examples: Mumbai pin codes route to the Navi Mumbai warehouse with Delhivery (best local SLA); B2B orders route to a dedicated B2B fulfilment centre; orders under ₹500 with thin margins restrict to economy carriers; same-day deliveries route to the nearest warehouse with a hyperlocal carrier like Shadowfax; and if all warehouses are out of stock, a backorder workflow triggers in the ERP.
How much money does intelligent order routing save?
One B4Ucommerce electronics customer saved ₹18 per order in shipping — ₹1.8 Cr per year at 10,000 orders/month — by routing to the optimal carrier instead of a single default contract. A fashion customer cut average delivery time from 4.2 to 3.1 days by routing to warehouses closer to the customer.
