Manufacturing in a Small Workshop: Recipes, Production Orders and the True Cost of Each Product

Why "materials cost" is not your real cost

Many small workshops price their products by adding up the materials and adding a margin. The problems show up later:

• The labor and the delivery of materials are paid, but never counted in the product.
• A batch planned for 50 pieces gives 48, and the cost of the missing two is spread nowhere.
• Material prices change, but the product price stays the same, and the margin quietly shrinks.

1. Write the recipe once

A recipe is the template for a product: the materials and their quantities for a standard quantity, plus the costs you pay every time, such as labor or delivery. For example, a recipe for 50 cakes lists the flour, sugar, eggs and butter they need.

A recipe never moves stock. It also tells you, from what is in stock right now, how many units you can make and an estimated unit cost — useful before you accept a large order. Editing a recipe later does not change earlier production, because each order keeps its own copy.

2. Open a production order when you start

When you start a batch, open a production order from the recipe. Opening it takes the materials out of stock right away, because they are now on the workbench rather than on the shelf. If a material is short, the app tells you how much is missing.

3. Close it with what really happened

When the batch is done, close the order and correct the quantities actually used and produced. Used more flour than planned? The extra is deducted. Some butter left over? It goes back to stock at the cost it left with. Then add the cost lines — labor, gas, delivery — each paid in cash from a fund or recorded on credit to a person.

4. The product enters stock at its true cost

When the order closes, the finished product enters stock at:

Say the materials came to 400, labor to 80 and delivery to 20: 500 in total. If you made 50 cakes, each costs 10. If only 48 came out, each costs about 10.42 — and that is the number your selling price has to beat. From then on, the profit on every sale of that product is calculated from its real cost.

5. Mistakes can be undone

If an order was opened by mistake, cancel it: the materials return to stock, the product is withdrawn and its cost lines are removed.

A routine for your workshop

1. Write a recipe for each product you make regularly.
2. Before a big order, check how many units your stock can make.
3. Open an order when the work starts, and close it when it ends with the real quantities and costs.
4. Compare each product's unit cost with its selling price every month or two.
