Know Your Costs
Trying to calculate food costs even with a spreadsheet can be really hard -- and when you're in a hot kitchen during service, it's almost impossible!
With the PlatePricer app for iPhone, you can calculate your food costs or menu prices in just seconds. So you can check a dish's food costs the very moment a cook is telling you about a change in its setup.
PlatePricer is available in the App Store for any iPhone.
Keep it simple, and don't sweat the small stuff
Most restaurant calculators and spreadsheets make you convert from the invoicing units (say, pounds), to your recipe amounts (for instance, grams). PlatePricer handles those conversions automatically.
Additionally, once you enter in a price for one ingredient, all your recipe costs will update -- you don't have to update them individually.
Lastly -- and I think this is extremely important -- you don't need to give exact pricing for all the inexpensive small stuff on the plate, like, say, onions and lettuce on a burger. You can just lump that into a fixed cost for the dish, however much you estimate. That's the industry standard for plate price calculations; they're based just on proteins and feature ingredients with a little fixed amount added on.
Using all the features is very simple and will allow you to stay no top of your costs with almost no time and effort.
