What are overhead categories for?

They group your fixed costs by kind, so you can see where the money goes. Fixed costs do not grow with each order, like rent. The preset categories are Shopify subscription, App costs, Salaries, Tools & software, Rent & storage, Agency & freelance, Compliance & fees and Miscellaneous. You can also name your own.

Grouping makes a slowly growing subscription bill visible in a way one total never does. A quarterly fixed cost review is the habit that catches it.

Two kinds of cost have a form of their own under Add cost instead. Marketing spend, like an influencer retainer, counts in marketing costs, because it is advertising, not rent. Other costs, one-offs like a repair, stay in overhead but get their own row on the P&L. So a month with a repair reads as normal overhead plus the repair. Each cost is counted exactly once either way.
