Custom Costs is a feature for you to add extra expenses to TrueProfit manually. As a seller on Shopify, there might be many different kinds of costs that incur in your store, for example taxes paid, Shopify subscription, KOL/influencers, or even Ad agencies costs. Basically, any costs that don’t fall into other existing categories in TrueProfit can be created and customized in the Custom Costs feature.

What are fixed costs and variable costs?
Fixed cost:

Example: Shopify subscription = $39/month, office rent = $500/month, or a one-time design fee = $200.
2. Variable cost:
A cost that is calculated as a percentage or formula, depending on your store’s performance.
Changes based on revenue or order value.
