2️⃣ Decide the reference price type from which you want to post the price change.

1. **Custom amount**. Define yourself the reference price at which you buy that product.
2. **Price of the last purchase**. haddock aligns the reference price with the price of the last purchase, i.e. the last invoice for that product.
3. **Pondered Average price**. haddock averages the price achieved within the period you select.
