Online Payment Platform (OPP), part of the Worldline Group and a leading payment provider for platforms and marketplaces, has announced a strategic partnership with SUNMI, a global provider of BIoT hardware solutions for retail and hospitality. The collaboration introduces a fully integrated payment and device ecosystem designed to simplify how software providers and resellers across Europe embed and monetize payments.
As SaaS platforms increasingly seek to offer seamless payment functionality within their core products, many have struggled with fragmented integrations, country-specific compliance requirements, and complex hardware dependencies. OPP’s ready-to-use payment infrastructure aims to eliminate those barriers by offering a unified platform that streamlines acquiring, compliance, reporting, and settlement across multiple European markets.

SUNMI complements this infrastructure with its portfolio of smart BIoT devices built for SoftPOS commerce and modern retail environments. Together, the companies are delivering a consolidated solution that brings payments, business applications, and hardware onto a single foundation. The result is a system that supports traditional in-store transactions, mobile payments, and self-service use cases without requiring separate integrations for each channel.
For development teams, the partnership reduces technical overhead. For sales and distribution teams, it removes friction in onboarding merchants. And for SaaS platforms operating across borders, it offers a faster, more predictable deployment model. By consolidating what has traditionally been a patchwork of providers and technologies, the joint solution creates a scalable framework that allows software companies to transform payments from a technical challenge into a recurring revenue stream.

Richard Straver, founder of OPP, emphasized that payments should function as a growth engine rather than an operational obstacle. He noted that the partnership removes long-standing complexity around integration and monetization, enabling SaaS platforms to launch more quickly and generate predictable revenue from embedded payment services.
Rather than requiring platforms to stitch together multiple acquiring partners, terminals, and regulatory processes in each country, OPP provides access to an integrated system supported by simple APIs and a scalable commercial model. This structure is particularly valuable for SaaS companies expanding across European markets, where regulatory and operational fragmentation often slows growth.
From SUNMI’s perspective, the partnership aligns with its broader vision of building a BIoT ecosystem that empowers fintech companies and independent software vendors to deliver tangible value at scale. By aligning its hardware portfolio with OPP’s embedded payment capabilities, SUNMI enables software providers to combine smart devices and integrated payments without increasing operational complexity.
Vincent Fillaut, Head of Payment at SUNMI, highlighted that bringing business applications and payment functionality onto a shared hardware and software infrastructure allows innovation to become practical and deployable rather than experimental.
The collaboration also strengthens Worldline’s broader SMB strategy. Joachim Goyvaerts, Head of SMB at Worldline, described the partnership as a way to make embedded payment functionality more accessible to software platforms across Europe by tightly integrating hardware and software capabilities.

Through this alliance, OPP extends its embedded payment infrastructure into brick-and-mortar retail and hospitality environments, allowing SaaS platforms to offer modern device-based payment experiences as part of a unified commercial offering. What once required significant scale and investment can now be delivered through a single integrated solution designed for rapid deployment and cross-border scalability.
As embedded finance continues reshaping the European payments landscape, the OPP and SUNMI partnership reflects a growing demand for unified platforms that reduce friction, simplify monetization, and enable true omnichannel commerce.
