How do I set up my FBM costs and VAT in Nova?

Open Costs & Taxes › FBM Costs in the left menu and give the ★ Primary card of each region a shipping rate. Then open Costs & Taxes › VAT and, on each card marked Tax calculated by you, set the category of your reduced-rate and zero-rated products. How Nova uses them: FBM costs, VAT.

Both pages serve Seller Central accounts. Admins and Workspace owners edit them; a Workspace member sees Ask to be Workspace owner.

In which order do I fill the FBM Costs page?

Cards are grouped by region, one per country you shipped to in the last 24 months.

  1. On each region's ★ Primary card (Mandatory input), click + Add rate next to Shipping, then Packing and Picking if you pay them. Cards ticked Use … costs read these rates. Rest of world prices every other country.
  2. For a country that costs more, click Enter own costs on its card.
  3. For a product that costs more, select its destination card, then click the product's row under Per-product FBM costs.

The form asks for From a specific date or All orders since day one, the amounts, and Shipping charged: per order or per unit. Packing is per order, picking per unit, and a product's shipping follows its destination's rule. Click Add period. A period reads Ongoing until a newer one starts, then Ended.

How do I set VAT categories?

Click a region card. Under Tax calculated by Amazon, the VAT Category column is read-only. Under Tax calculated by you, click a product's cell:

  • EU: search Amazon's categories, such as A_BOOKS_GEN.
  • UK and Mexico: pick Standard rate, Reduced rate or Zero-rated.

Standard rate · default means no category: Nova applies the last rate Amazon charged on the product, else the country's standard rate. Missing VAT lists these products.

The account's default category has no button: set it from your AI assistant, for example A_NOVA_ZERO if you sell VAT-free or handle VAT outside Nova.

Can my AI assistant do it?

Yes. Click Copy the prompt in the banner of either page, then drop your carrier grid or product list into Claude, ChatGPT or Gemini connected to Nova (Connect Claude). Nothing is saved until you confirm the preview.
