Documentation Mercado Libre### How does it work?The Net Proceeds model was developed to **protect your net profit margin (Net Proceeds)**,ensuring that the value you define as your earning is always maintained. To achieve this,the **public price** (the final value displayed to the buyer) becomes a variable that is**automatically adjusted** by our system. This adjustment occurs whenever there arefluctuations in **variable costs** (such as shipping costs, commissions, or fees), ensuring that:**Public Price = Your Fixed Net Proceeds + Fluctuating Variable Costs**In this way, if a variable cost increases or decreases, the value of your**Net Proceeds does not change**, only updating the **public price**.If you wish to change your profit, simply edit the Net Proceeds value directly.### Practical example:* **Publishing flow with Net Proceeds:** the seller informs "net_proceeds": 13, and the system automatically calculates the listing price (USD 13 + USD 3 + USD 4 = USD 20).With this new logic, the focus shifts from the listing price to the net proceeds, optimizing item publication and ensuring greater transparency about the amounts actually received.### Publishing with Net ProceedsNet Proceeds can be configured in different ways when publishing an item. Below, we present the available options so you can choose the one that best fits your integration.When using the **"net_proceeds"** field, it is not necessary to include the "price" field, as the system will automatically calculate the listing price based on applicable fees and shipping costs.### Compatibility Rules by Logistic TypeTo ensure the correct creation of items on the target sites, follow the compatibility rules by logistic type:The system automatically calculates the listing price based on fees and shipping.The final Listing Price must be provided. The use of the "net_proceeds" field will cause a validation error.### Configuration by Sites to SellThe same call, in code.
