Mondu review June 2024

We take a closer look at the buy now pay later products available with Mondu.

The “buy now pay later” (BNPL) industry is continuing to boom and is currently the fastest-growing online payments method in the UK. BNPL is a service that allows consumers to shop online and place orders without having to pay the full amount upfront.

But as well as proving popular in the B2C e-commerce sector, BNPL is also taking off in the B2B e-commerce space thanks to providers like Mondu.

What is Mondu?

Founded in 2021, Berlin-based Mondu launched in the UK in March 2023. The payments fintech enables B2B merchants and marketplaces to offer BNPL payment methods to their business customers. The company also operates in Austria and the Netherlands and has also expanded into France, although it is currently only available for buyers.

What does Mondu offer?

Mondu offers a BNPL solution for online checkouts so that businesses can offer their customers an alternative payment method and flexible terms. These services let customers buy goods and services and pay for them later.

In February 2023, Mondu also launched MonduSell, a new solution that offers BNPL across multiple sales channels, including over the phone, onsite, and by email.

How does Mondu work?

By integrating Mondu into your online checkout, your business customers will be able to buy the goods and services they need and then opt to pay for them at a later date. You, as the merchant, get paid promptly after an order has been placed, protecting you against the risk of default. Mondu also reduces the operational tasks associated with payment allocation and in the event of a missed payment deadline, Mondu will take care of chasing and collecting payments on your behalf.

Merchants can integrate various BNPL payment methods into their checkout. Buyers can choose to pay their invoice in 30, 45, 60 or 90 days or can opt for 3, 6, or 12 monthly instalments via Mondu’s instalments plan.

Mondu’s payment methods currently include purchase on account by bank transfer, purchase on account by SEPA direct debit, and purchase by instalments.

According to Mondu, merchants that offer flexible payment terms can gain a competitive advantage while increasing their conversion rate, average order values and sales.

How much does Mondu cost?

Exact costs are currently unclear but Mondu says its partner bank will send you the invoice payment, minus the billing amount and the VAT due. You will also receive a payout report from Mondu that will explain what has been purchased, along with what fee has been applied and what sales tax has been incurred.
