Using the Bill of material gives you accurate cost at all times!

So, with a burger for example - you will create the

bun - supplier quantity 12 (Dozen) & qty used in burger 1

Patty - Supplier qty 50 (Box) qty used 1

Tomato - Supplier qty 1 (kg) qty used .1 (100gram)

Lettuce - Supplier qty 1 (kg) qty used .05 (50gram)

Now, as you enter the purchased of the ingredients, the costs of these items will be correct & therefore your cost of the burger will be correct. You can then use a matrix to calculate the selling from cost, but be careful as it may change the burger price daily as your costs go up!

Potatoes is easier to work with in kg. So today if you are buying a 7kg bag - enter the qty as 7, tomorrow it may be 10kg, so you purchased qty of 10 etc. it means your costs are always correct based on the market! The average cost will calculate the weighted average for you & thus you can determine your TRUE profit!
