Our Experience
KLEVERBILL was conceptualized in 2016 and launched in 2018 with our first pilot customer. From the beginning, the software has been developed and optimized in close collaboration with users. Since the launch, KLEVERBILL has been continuously enhanced based on real operational requirements.
Since 1995, S/F/G Forderungsmanagement GmbH has collaborated with companies all facing the same challenges: unpaid invoices, awkward reminder calls, chaotic Excel sheets, loss of time, and pressure on cash flow. We observed how much energy was being diverted to administration rather than growth and how easily customer relationships could suffer due to impersonal or poorly timed reminders.
In 2016, we resolved to address this issue fundamentally, not by increasing personnel, but by enhancing our systems.
KLEVERBILL was developed in collaboration with actual clients who were frustrated with the manual process of chasing payments. Each feature is informed by real invoices, actual objections, genuine delays, and the true financial pressures faced by companies with an annual recurring revenue of 1-10 million euros.
The goal was simple: Provide businesses with control, clarity, and peace of mind in their receivables process.
Heute treibt diese Mission immer noch alles an, was wir entwickeln. KLEVERBILL unterstützt Unternehmen dabei, schneller bezahlt zu werden, Stress in der Buchhaltung zu reduzieren und ihre Kundenbeziehungen zu schützen – alles durch vollständig anpassbare Automatisierung, kompromisslose Sicherheit und vollständige Transparenz.
What used to be a source of daily frustration has now become a seamless system operating in the background, allowing businesses to concentrate on their core priorities.
