Does PrestaShop core validate EU VAT numbers?

It can store vat_number. It does not call VIES or automatically apply intra-community reverse charge. Tax still comes from tax rules and addresses unless a module hooks TaxManager.

Is B2B coming to PrestaShop core?

There is an experimental B2B foundations discussion in core. Until that ships and covers reverse charge, proforma, and locked company identifiers, merchants still need focused modules.

Should a first addon also generate Italian XML e-invoices?

Usually no. Collecting SDI/PEC and VIES evidence is a different job from submitting FatturaPA. Keep the first release reviewable.

PrestaShop Addon Gaps Worth Building in 2026

Core PrestaShop still stores a VAT number without VIES, skips reverse charge on the invoice, and treats B2B company IDs as editable fields. Those legal and stock jobs are module-sized.

PrestaShop is already a catalog, cart, and PDF invoice engine. The addons worth voting on in 2026 sit where EU B2B law and warehouse reality diverge from those three screens. Core can print a VAT number on an invoice without ever asking VIES whether the number is live. Reverse charge is not a native tax outcome. A customer can change their company identifier after the first order and break the ERP match. Payment-pending orders do not always reserve stock the way a B2B desk expects. Agencies have been listing these as project boilerplate for years; GitHub’s B2B foundations thread makes the same inventory of gaps explicit.

A useful PrestaShop addon draft is a back-office page with the cyan header and dark menu merchants already know — not a WordPress dashboard and not a Shopify admin. The first release should do one legal or stock job: VIES plus a reverse-charge mention, a proforma before payment, a warehouse transfer, a combination-level low-stock digest.

How to judge a module proposal

Name the PrestaShop version, the tax-address setting, and the order state that triggers the job. Say what will not ship: a full accounting suite, a replacement for native cart rules, or XML already handled by a local e-invoicing specialist. Then vote. DraftPlugins will not list a module on PrestaShop Addons until the community threshold is reached and a release exists.
