The goal
My client, an established B2B service provider, faced a task with a hard deadline: around 5,000 customers had to complete a legally required contract change within a few weeks. Speed was essential, and the system had to be live by the cut-off date, no exceptions. Ordering, payment and invoicing had to work together reliably from day one. Doing this by hand would have tied up the entire team for weeks, if not months.
What they needed was a solution that could go live fast, fit into their existing systems and give customers a simple path.
The approach
Focus on what matters. At the start, the client and I defined what was essential for launch and what could wait. That way every hour went into features that were needed from the first day.
Connect existing systems instead of replacing them. I built the platform with SvelteKit and TypeScript and connected it directly to the existing setup: Mollie for payments, Fastbill for invoicing, the company’s customer portal and automated emails. Payment, invoice and customer account now work together without manual steps.
Privacy from the start. The platform is GDPR compliant, and payments and billing run through EU-based providers.
The platform went live after 14 days.
The result
In the first four weeks, around 5,000 customers used the platform and processed €1.2 million in net revenue through it.
- €1.2 million net in four weeks, fully paid and invoiced online
- 5,000 customers without manual case handling
- Several thousand working hours saved, because payment matching, invoicing and confirmations run automatically
- 14 days from requirements to launch
Instead of matching payments and writing invoices, the team could focus on its customers.
