bexio is a Swiss business management platform used by over 100,000 paying SMB customers for customer management, order processing, and bookkeeping. We've been bexio's embedded backend engineering partner since 2021 - supporting the platform as it doubled its customer base, from ~50,000 paying customers to over 100,000. Our engineers work across bexio's internal engineering organization - not as an external vendor running a siloed project, but as an integrated extension of their team.
What we do
Platform maintenanceKeeping production reliable for 100,000+ paying customers. Monitoring, incident response, and operational stability.
Ongoing refactoringModernizing the existing codebase incrementally as part of normal feature work. No big-bang rewrites - steady improvement alongside delivery.
New feature developmentBuilding what comes next on the product roadmap as bexio grows.
Swiss banking and compliance
The highest-impact work has been connecting bexio to Switzerland's financial infrastructure.
Swiss bank integrations - We onboarded banks one by one through direct bank APIs and bLink - SIX Group's open-finance interface, which bexio was among the first accounting platforms to join. Designed integration patterns that scale across banking partners. bexio customers can pull statements and execute payments end-to-end inside the platform.
Swissdec certification - We implemented and obtained Swissdec certification, the Swiss standard for payroll data exchange between employers, insurers, and authorities. This lets bexio process compliant payroll and insurance flows for Swiss SMBs. Compliance work owned end-to-end by our team.
The stack
Scala with ZIO and cats for functional backend services. Java with Spring for parts of the existing platform. Infrastructure on GCP. The dual-stack reflects a mature codebase: we work fluently across both and modernize as we go.
For companies evaluating our Scala expertise, bexio is the reference: five years of production Scala/ZIO at scale for a regulated European SaaS.
Why five years matters
Any team can deliver a project. Staying embedded in an engineering organization for five years - across product changes, team rotations, and scaling - requires consistent quality, reliable people, and the ability to work inside someone else's standards rather than imposing your own.
bexio didn't hire us for a project. They hired us as part of their team. Five years later, we're still there.
Same timezone, no friction
bexio is in Switzerland. We're in Serbia. Both CET. Full working day overlap, no adjustment. Daily standups, code reviews, and sprint planning happen in normal Swiss business hours.
For European companies evaluating nearshore partners, this is the proof point: five years of embedded delivery in the same timezone with zero communication friction.
