Work Order vs Sales Order vs Job Card

Ever wondered how a customer's simple request for a product transforms into a concrete task on the factory floor? 🤔 In the world of manufacturing, it's all about a clear, logical flow of information. Without a structured process, turning customer orders into finished goods would be chaotic.
Think of it like a chain of command in a well-organized project. Each document has a specific purpose and triggers the next step in the process. This ensures that what the customer wants is exactly what gets produced, efficiently and trackably.
Here is a visual representation of this workflow:
Sales Order ➝ Production Plan ➝ Work Order ➝ Job Card
Sales Order
: This is the customer's request. It says, "We need 100 shirts." Work Order
: This is the internal production plan. It translates the customer's request into a manufacturing task, saying, "We will produce 100 shirts for this specific Sales Order
." Job Card
: This is the actual task on the factory floor. It says, "This workstation is now making 25 of the 100 shirts planned in that Work Order
." The Work Order
acts as the crucial bridge.
The Job Card
is linked to the Work Order
, and the Work Order
is linked to the Sales Order
.
Without the Work Order
, there is no direct, standard connection between a Job Card
and a Sales Order
.
Let's look at each component in detail.
A Sales Order is the starting point of the entire manufacturing journey. It's the official document confirming a sale with a customer.
This document contains all the crucial details from the customer's perspective: what they want, how many they want, what price they agreed to, and when they need it.
A Work Order is the internal production plan. It acts as the master instruction sheet, translating the customer-facing Sales Order
into a language the production team can understand and execute.

authorizes the consumption of raw materials, allocates resources, and schedules the production run.
It's the central hub that connects the sales department's promise to the factory's actions.
A Job Card (sometimes called a job ticket or work ticket) is the most granular instruction. It's a specific task assigned to a particular workstation or employee, derived from the broader Work Order
. A single Work Order
can be broken down into multiple Job Cards

Understanding this hierarchy is the first step toward streamlining your production and ensuring that every task on the floor is perfectly aligned with customer demand. ✨
