Growth in the solar industry: How Tepto transformed from 100% B2C to 75% B2B with flexible B2B payments

The solar industry is booming – but for retailers, rapid growth brings new challenges. More and more business customers are demanding flexible payment options that align with their project cycles. Tepto recognised early on that flexible payment solutions would become a decisive competitive advantage. With Mondu as their partner, the solar specialist achieved an impressive transformation – from a pure consumer business to a company that now generates 75 percent of its revenue from business customers.

About Tepto

Tepto was founded in 2012 and has grown from a company with 10 employees to a leading provider in the solar industry with over 100 staff members. The company processes more than 200 orders daily and operates an impressive 40,000 m² of warehouse space. Most of Tepto’s business customers are tradespeople and young companies, often still in the early stages of their business operations.

Flexible payments in the solar industry

In the solar industry, much of the business runs on personal relationships and direct customer contact. Solar retailers and installers are constantly on the move – on rooftops, in their vans between appointments, or in the workshop in the evening. They need a partner who offers flexibility. That’s why Tepto customers can order however it suits them: by phone, via WhatsApp, in the online shop, by email, or directly on-site at the warehouse.

Just as important as quick ordering channels are realistic payment terms. Installers purchase from Tepto, install the system at the end customer’s site, and only then receive their payment. This can take weeks. Tepto knew the problem but initially only offered prepayment – the industry seemed too risky. As more and more customers requested invoice payment, it became clear: without more flexible payment options, Tepto would lose business.

Tailored B2B payment solutions for the solar industry

With Mondu, Tepto has implemented a comprehensive B2B payment solution that is available both in the online shop and in personal sales via MonduSell. The flexible Buy Now, Pay Later options specifically address the unique challenges of the solar industry:

  • Material pre-financing: Solar retailers can order components and only pay after receiving payment from their end customers
  • Project flexibility: Unplanned changes or extensions don’t strain liquidity
  • Sales optimisation: Retailers only pay when they actually sell the goods to their customers

Tepto’s customers benefit primarily from improved cash flow through payment deferrals and can realise larger investments in solar systems through instalment payments – without straining their liquidity.

Why Tepto chose Mondu: The deciding factors for the partnership were the high approval rates even for young companies, generous buyer limits, and the customised solutions tailored precisely to Tepto’s business requirements. Additionally, Mondu’s seamless checkout process convinced them, functioning smoothly both online and in field sales.

Successful implementation

The integration of Mondu was quick and straightforward. Via Shopware, Mondu could be easily activated within the existing online shop structure, while the offline solution MonduSell was immediately deployed by account managers for field sales.

Since partnering with Mondu, Tepto has recorded remarkable B2B growth: the flexible payment terms and omnichannel solution enabled Tepto to reorient its business – from an originally pure B2C business to a focus of 75% in the B2B sector. The results are clear: with a 10% increase in conversion rate and an average approval rate of at least 93%, the success of the partnership is reflected in concrete numbers.

We’re here to help you turn payments into your growth engine.
