Manage your shop’s VAT

Set up VAT, choose your scheme (domestic or OSS), select the reduced rates for each product, and manage your returns.

By default, your shop is VAT-exempt: no VAT is charged and your invoices will state ‘VAT not applicable’. You don’t need to do anything. This article explains how to enable and manage VAT if your business is liable for it.

Winslor calculates and displays VAT for you, but it does not replace your accountant: it is your accountant who determines whether you need to charge VAT, at what rate, and under which scheme. This article explains how the tool works; it is not intended as tax advice.

The principle: your prices include VAT

The prices you enter include all taxes (TTC). Enabling VAT therefore never changes the price paid by the customer: it simply breaks down this price into the pre-tax amount (HT) and VAT on the invoice. Please note: your pre-tax margin is reduced by the amount of VAT deducted from the price.

Enable VAT

  1. Go to Settings → General, VAT section.
  2. Tick the box marked ‘I charge VAT’.
  3. Enter your standard rate (e.g. 20 for France).
  4. Choose your tariff: ‘Mon taux partout’ (domestic) or ‘OSS’.
  5. Record.

The two diets

Domestic (default)

You charge your standard rate to all your customers in the European Union; sales outside the EU are charged at 0% (exports). This is the scheme you should use as long as your sales to other EU countries remain below the threshold set out below.

OSS (one-stop shop)

You charge the VAT rate applicable in the customer’s country for your sales to private individuals within the EU: the customer always pays the same price including VAT, but the VAT is paid to their country. This is mandatory if your annual sales to private individuals in other EU countries exceed €10,000.

The Invoices page displays a threshold indicator: it totals your sales to other EU countries for the year and alerts you when you approach or exceed €10,000. This is the time to switch to the OSS scheme.

Reduced rates by product

If a product is subject to a reduced rate (e.g. a book), enter the rate in the ‘VAT (%)’ field on its product page. Leave it blank to apply the shop’s default rate. Reduced rates apply to domestic sales; for OSS, the standard rate of the destination country applies.

Your invoices and accounts

Each paid order automatically generates a numbered invoice (continuous numbering, without a perforation). When VAT is enabled, the invoice shows the total excluding VAT, VAT by rate and the total including VAT; otherwise, it states that VAT is exempt.

Find all your invoices in the ‘Invoices’ section (admin menu), where you can filter them by year. The CSV export includes the country and rate for each sale — allowing you to break down the VAT collected by country for your tax returns (standard return for France, OSS return for other EU countries).

A sale outside the EU is an export subject to 0% VAT. However, the customer may have to pay import duties on receipt, depending on their country.
