Libra Energy B2B commerce platform

Libra Energy is a wholesaler for anything to do with renewable energy: solar panels, battery storage, EV charging and any installation material an installer may need. Those installers order the materials for the job they are on, often the same day. Libra wanted its webshop to do more than take those orders. It wanted the webshop to bring in new customers. The first chance was Solar Solutions Amsterdam in March 2026, where Libra was launching new products and planned to sign up new customers at its stand.

The existing webshop had served Libra well while the business was smaller, but it was not built for this next step. It depended on an external supplier's systems, which were due to be retired, so a change was coming anyway. Installers could order if they knew the article number. They could not search by name or specification, see product images, or order on account with a live credit check.

For Rensa Family, the group Libra belongs to, the project mattered beyond Libra. Libra would be the first of the group's labels (its brands) on a shared composable commerce platform. If it worked, the other labels would follow on the same foundation, starting with Rensa, the group's main brand, planned for 2026.

We built one multi-label platform on commercetools, Contentful, Algolia and Mollie, with a single integration layer to Rensa's systems. Evolve, our own accelerator platform, connects the storefronts to those services through one GraphQL endpoint. Libra was the first label on it.

From December 2025, while the old webshop kept running, we invited Libra's largest customers onto the new platform. By mid-February, 90 customers were placing 15% of all Libra orders there. Those real orders showed us where the platform needed work, weeks before the full switch, so Libra could base the go-live decision on evidence from real customers.

Because the launch date was fixed, Libra and Lab Digital agreed what installers needed on day one and built that first. Everything else followed in the weeks after launch, once the platform was live and taking orders. Rensa's security and infrastructure teams worked with us throughout, so the platform met the group's security requirements from its first day.

Every feature is built around how an installer works: find the right product quickly, see your own price and stock, and order in the way your business is set up to buy.

Libra Energy went live on 3 March 2026 with all of its active customers on the new platform, one week before Solar Solutions Amsterdam. The switch took one evening.

Installers found the new webshop easier to use. Their customer effort score, which measures how easy it is for customers to get things done, rose from 6.1 to 6.7 out of 7 after go-live.

Libra's platform is now the documented blueprint for Rensa Family's other labels. A roll-out plan describes how a new label storefront is set up on the same foundation, and Rensa is next.

Much of Libra's demand never reaches the webshop. An installer quotes a job to their own customer, then forwards the same quote to Libra as a PDF or Excel attachment. Until recently, someone at Libra read each document and rebuilt the list by hand in the catalogue. That took around 30 minutes per quote, ten or more times a day, and the installer waited several hours or a full working day for a priced list.

An AI agent now does that work. The installer forwards the quote to a Libra mailbox. The agent reads the attachment, whatever the format, and finds each line in the catalogue. It creates a shopping list on the platform and replies in the installer's own language, listing anything it could not find. The installer opens the link, logs in, sees their own contract prices and current stock, and adds the whole list to the cart in one click. A Libra account manager checks each list before the reply goes out.

Why this was possible

The agent uses the same gateway and the same authentication as the webshop, so it can do only what the webshop can do. It never sees pricing or stock; those appear when the installer logs in. The commerce platform was built as a set of services with one typed interface, so we only had to give the agent access to services that already existed. The same layer is ready for returns handling, an assistant inside the storefront, and the roll-out to Rensa.
