# What Do I Need to Do to Set Up Vendorati for Amazon FBA?

Vendorati is **mandatory** for Amazon FBA accounting with Companio. Without it, we cannot retrieve your Amazon sales data or support your accounting.

# Why Vendorati Is Required?

Vendorati provides the **only consolidated Amazon FBA sales report** we need.
Once connected:
* You no longer need to upload invoices or Amazon reports.
* Companio collects the data automatically.
* Your accounting becomes simpler and fully handled by us.

# What Is the Cost?

Vendorati’s Starter Plan costs 25 EUR/month. The amount is added to your credits each month.


# How to Complete the Setup?

1. **Sign up for Vendorati** and subscribe to the Starter Plan.
(Trial accounts do not allow access — they are not accepted.)
2. **Connect your Amazon Seller Central account** inside Vendorati.
3. **Grant Delegated Access**:
Go to **My Account → Delegate Access** and grant **Administrator** access to us.

Once access is granted:
* You do **not** need to upload any Amazon sales documents.
* Companio retrieves all necessary data from Vendorati automatically.
