Calculate →Why These Tools?
In e-commerce, profit doesn't come from a single number. To see what an order actually earns you, the desi, the shipping fee, the marketplace commission and the VAT you need to account for all of it at once. These tools exist to unpick that chain piece by piece.
A typical flow works like this:
- Paketin its desi — the shipping fee is calculated from this.
- the shipping fee and work out your free-shipping threshold.
- If you sell on a marketplace the commission subtract.
- With the remaining amount your profit marginmeasure it.
- When you publish the price the VAT and, if any, the discount reflect it accurately.
To track your products in the warehouse and in transit the barcode generatoryou can use.
