Service DAOs: Skip this step!If you’re running a SaaS, subscription, or consulting business (like Zenland DAO), you don’t need to track inventory. Skip to Record Income instead.
Resources are the raw materials, ingredients, and supplies that get consumed to create your products. Think of them as the inputs that go into what you sell.

Cost Tracking (Weighted Average)

OpenBook uses Weighted Average Cost (WAC) for inventory valuation. Here’s how it works:
When you purchase inventory at different prices, OpenBook calculates the average:Example:
  1. You have 1,000g of beans at 0.02/g=0.02/g = 20.00
  2. You buy 2,000g more at 0.025/g=0.025/g = 50.00
  3. New WAC = (20+20 + 50) / (1,000 + 2,000) = $0.0233/g
This average cost is used for Cost of Goods Sold (COGS) when you make a sale.
You don’t need to set the initial cost manually. It will be calculated when you receive your first inventory (Step 7).
