Cost-up pricing for makers. Every sale profitable by design.
What do you buy and how much of it goes into one finished piece?
Per-item packaging cost. Tracked separately per selling channel — shipping envelopes for online orders, a small box or bag for market day, etc.
How long does it take to make one piece and at what rate? Add a row per person or task. Hourly (enter rate + minutes per piece) or a flat cost per unit.
Recurring fixed costs (studio rent, subscriptions) that apply regardless of selling channel. Use "Monthly ÷ output" to spread a fixed monthly cost over your production volume.
