Mifumo

Manufacturing

Write recipes for what you make, plan production runs, issue materials from stock and put finished goods into stock at what they really cost.

Getting started

The Manufacturing link appears in the menu when your plan includes the Manufacturing module. The module brings Inventory with it, including Shipments and landed cost and the stock reports, so you don't need to add Inventory separately.

  1. Add your finished products and raw materials under Products and services with Track stock ticked. Recipes only use stocked products.
  2. Receive your raw materials into stock as usual, on a bill or a goods received note. For imported or delivered materials, put freight, duty and transport on the same shipment under Inventory, then Shipments and landed cost, so the materials go into stock at their landed cost.
  3. Open Manufacturing, then Manufacturing settings, and switch on only what you need. With everything off you get recipes, production orders and the true material cost of each product.
  4. Open Recipes and click New recipe.
  5. Plan your first production order from the recipe.

How to

Create a recipe

A recipe (bill of materials) lists what one batch of a product uses.

  1. Open Manufacturing, then Recipes, and click New recipe.
  2. Choose the Finished product. The Recipe name defaults to the product name.
  3. Enter how much One batch makes, in the product's own unit.
  4. For each material, choose it and enter the Quantity per batch and any Expected wastage %. Click Add material for more rows.
  5. Add notes on the method, mixing order or quality checks if you like.
  6. Click Save recipe.

Each quantity is in that product's own unit, shown next to the box, and can have decimals, for example 12.5 kg. You can also type a weight or volume with its unit and Mifumo converts it: 250 ml for a material kept in litres saves as 0.25 L, 500 g for one kept in kg saves as 0.5 kg. Wastage is added on top when you plan production: 100 kg with 2% wastage plans 102 kg. The recipe page shows what the materials for one batch cost at today's stock cost.

Plan a production order

  1. Open Manufacturing, then Production orders, and click New production order. You can also click Plan production on a recipe.
  2. Choose the Recipe and enter the Quantity to make.
  3. Set the Production date.
  4. Choose the store to Take materials from and the store to Put finished goods in.
  5. Click Plan production.

The order opens as Planned. Its Materials table shows what the recipe needs, what is on hand in the store, and anything short.

Start production

  1. Open the planned order.
  2. If any material is short, receive or transfer it into the store first. Production cannot start while materials are short.
  3. Click Start production (issue materials).

The materials leave stock at FIFO cost and move into work in progress. The order becomes In production.

Record the output

  1. Open the order that is In production.
  2. Under Record the output, enter the Good units produced, any Scrapped or rejected units, and the Finished on date.
  3. If lot numbers or expiry dates are switched on, enter the Lot number and Expiry date.
  4. Click Receive finished goods.

The finished goods go into stock at their actual cost: materials, plus labour and overhead if you use them. The cost of scrapped units stays in the good units. The order shows the cost per unit and links to both journal entries.

Record a finished run in one step

  1. Open the planned order.
  2. Open Already finished? Record the whole run in one step.
  3. Fill in the output as above and click Issue materials and receive finished goods.

Record what a run really used

This needs Record actual material usage switched on in the settings.

  1. Open the planned order.
  2. In the To issue column, change the quantity of any material the batch used more or less of.
  3. Click Save quantities, then start production.

The difference from the recipe shows as a variance on the order and on the costing report.

Void a production order

  1. Open the order that is in production or completed.
  2. Open Void this production order, give a reason and click Void and put the materials back.

The finished goods come out of stock, the materials go back on the shelf, and both postings are reversed. This only works while none of the finished goods have been sold. You need a role that can approve. A planned order that has not started can simply be removed with Delete.

See what each product cost to make

  1. Open Manufacturing, then Production costing.
  2. Choose the From and To dates and click Show.

By product shows the runs, quantity produced, scrap, materials, labour, overhead and average cost per unit. Each run shows each completed order and how far material use was above or below the recipe.

Settings

Open Manufacturing, then Manufacturing settings.

Questions

Why can't I find my product when I create a recipe?

Only stocked products appear. Open the product under Products and services and tick Track stock.

Why is the Start production button greyed out?

Some materials are short in the store you chose. Receive or transfer them first, or plan the order from a different store.

Can I make a product in kilograms from materials in litres?

Yes. Each product keeps its own unit, so a recipe can mix weight, volume and count.

How do I make a product measured by volume?

Give the product a volume unit, such as L or ml, under its product details, and enter One batch makes in that unit: a 200 L batch of juice. Materials kept in litres or millilitres are entered the same way. To sell in bottles, keep the bulk liquid as one product in litres and the bottled drink as another in pcs: its recipe uses 0.5 L of the liquid, one bottle and one cap.

Which units does Mifumo convert?

ml, cl and L (litres) between each other, and mg, g, kg and tonnes between each other. It does not turn weight into volume, because that depends on the material: if you buy cooking oil by the kg but measure it in litres, keep it in one unit and enter the recipe in that unit. Stock keeps three decimals of a product's unit, so the smallest amount of a material kept in litres is 1 ml, and of one kept in kg is 1 g. For a pinch of something, keep that material in g or ml.

Why can't I void a completed order?

Finished goods from that run have already been sold. A void needs all of them still in stock.
