European rules,in your own store.

Brightfern Labs builds two WooCommerce plugins: e-invoices that follow the European standard EN 16931 and are checked before they are sent, and a record of your packaging per country.

  • Both free on WordPress.org
  • No customer data sent to Brightfern Labs
  • Made in Kortgene, the Netherlands

Brightfern E-Invoicing

Checked before they leave.

Turn orders into e-invoices that follow EN 16931, in four formats. Every invoice is checked before it is sent, and incoming e-invoices land in your own inbox.

The format your customer's country asks for.

Ombel Packaging Records

Weigh once. Every order counts.

Record how much cardboard, plastic and other packaging material you ship to which country, for every order. A clean basis for your packaging declaration under the PPWR and national EPR rules.

Create a profile with the materials and weights of your packaging. When it changes, you create a new version; earlier figures stay as they were.

Packaging profiles with versions. The 141 g shipping box got a second version of 121 g.

Link profiles to your products. For every new order the plugin records which material goes to which country, including the shipping packaging.

On WordPress.org the plugin is called Ombel Packaging Records for WooCommerce.

Clear about rules, careful with your data.

Regulation is complicated enough. The plugins keep it clear and honest.

  • Check first.

    E-invoices are checked before they are sent: against the rules of the format, your customer's VAT number and whether they can be reached on Peppol. You see a mistake now, not after a rejection.

  • Your data stays with you.

    Both plugins run inside your own WordPress. Your orders and customer data are not sent to Brightfern Labs servers.

  • Honest about what it does.

    No "one-click compliance". The plugins show what is done, what is still missing and what you need to do yourself.

Small company, direct lines.

Brightfern Labs is a software company from Kortgene, in the Dutch province of Zeeland.

We build and publish plugins for WooCommerce stores that sell across Europe. When you ask a question, the answer comes from the person who builds the plugin.

The name comes from the fern: a frond that unfurls step by step. That is how we build, too. Start small, grow carefully.

Install for free from WordPress.org.

Both plugins run inside your own WordPress. You don't need an account with us.
