Sandorian: Software Integration Partner for European Labs

Sandorian is a software engineering and integration partner for established European companies. Headquartered in Rijen, the Netherlands, with a distributed team across Europe, Sandorian builds the software layer around laboratory systems - covering workflows a LIMS doesn't address - and delivers compliance-first integrations for testing, calibration, and diagnostic labs under ISO 17025, ISO 15189, and IVDR. Sandorian also serves fintech product teams, energy operators, R&D institutes, and customs brokers - connected by a single engineering philosophy: compliance is the starting point, not the finish line.

What we build

Every industry Sandorian works in shares one trait: off-the-shelf software runs out of road exactly where the regulated workflow gets complicated. That's the gap Sandorian fills - with purpose-built integrations, portals, and middleware that keep client operations running and auditors satisfied.

A checklist of four purpose-built software layers Sandorian adds around an existing LIMS: sample registration portals, instrument middleware, eIDAS-sealed certificate portals, and audit trail and…

Lab software that covers what your LIMS doesn't

A Laboratory Information Management System handles sample tracking and results storage. What it rarely handles well: customer-facing request intake, instrument middleware, certificate delivery with legally binding signatures, and the CAPA and audit trail workflows that ISO 17025:2017 and ISO 15189:2022 inspectors scrutinize most closely.

Sandorian builds the software layer around your existing LIMS rather than replacing it. That means purpose-built tools for the parts of your workflow that your LIMS vendor never covered:

  • Sample registration portals - structured intake forms that feed directly into your LIMS workflow, reducing transcription errors and processing time
  • Instrument middleware - bidirectional bridges between analyzers, balances, and measurement equipment and your LIS or LIMS, using HL7 and ASTM protocol adapters where the instrument manufacturer's software stops short
  • eIDAS-sealed certificate portals - client-facing portals where calibration and test certificates carry qualified electronic signatures under eIDAS Regulation EU 910/2014, giving end customers legally valid, tamper-evident documents without a paper chase
  • Audit trail and CAPA tooling - structured deviation logging, corrective and preventive action workflows, and ALCOA+-aligned data integrity controls that sit on top of or alongside your LIMS

I've seen labs stall accreditation renewals for months because their LIMS vendor's API documentation was three versions out of date and their middleware vendor had been acquired. That's a compliance risk, not a software problem - and it's exactly the kind of situation Sandorian is built to resolve. Read more about what audit-ready lab software actually needs and the most common causes of lab integration failure in Sandorian's knowledge base.

Compliant by design: ISO 17025 · ISO 15189 · IVDR · eIDAS - built in from the first sprint, not bolted on before go-live.

For diagnostics labs operating under IVDR (EU 2017/746), Sandorian covers the specific software validation and documentation requirements the regulation imposes - including traceability, clinical performance data management, and post-market surveillance data flows. The IVDR compliance roadmap for laboratory software lays out exactly what that means in practice.

Payments and fintech engineering

Sandorian is a Mollie Preferred Integration Partner - a third-party verified credential that reflects sustained, production-grade delivery on Mollie's payment infrastructure. That partnership shapes how Sandorian approaches fintech work: PSP selection, API integration architecture, subscription billing, and KYC/KYB workflow design are treated as engineering problems with compliance consequences, not just plumbing tasks.

Key capabilities in the fintech vertical:

  • PSP integration and payment orchestration using Mollie's REST API, with webhook handling, idempotency patterns, and reconciliation pipelines
  • Subscription billing on Laravel applications using laravel-cashier-mollie, the open-source library Sandorian maintains
  • KYC and KYB workflow design for European fintech products under PSD3 and PSR requirements
  • Open banking API connectivity and account data aggregation patterns
  • Multi-tenant SaaS billing architecture for European platforms

Energy platform integration

Energy operators across Europe face a version of the same problem labs do: proprietary systems, legacy SCADA infrastructure, and data pipelines built for a single-source grid that now need to talk to spot markets, smart meters, and balancing platforms at the same time.

Sandorian builds integration layers for energy platforms that connect SCADA systems to modern software stacks, normalize smart meter data streams, and connect operators to European power exchange APIs including ENTSO-E and day-ahead market feeds. The compliance angle here is data integrity and auditability - the same engineering discipline that governs lab software.

Software for R&D institutes and customs brokers

R&D institutes need software that tracks innovation pipelines - from grant application through prototype, pilot, and commercialization - in a way that satisfies both internal governance and external reporting requirements. Sandorian builds structured innovation pipeline software that replaces spreadsheet-driven processes without forcing a generic project management tool onto a highly specialized workflow.

For customs brokers and logistics operators, Sandorian builds document workflow tools that handle the structured, legally significant data flows customs declarations require - with the same audit trail discipline applied across lab and fintech work.

Who we work with

Sandorian's clients are established European companies in regulated industries. They share a profile: they have an existing system landscape, they cannot afford compliance gaps, and they need a technical partner who understands their regulatory environment before a single line of code is written.

The people who typically reach out are:

  • Lab managers and QA leads at calibration, testing, or diagnostic labs seeking to close the gap between their LIMS and their compliance obligations
  • Diagnostics and testing lab operations teams working toward or maintaining ISO 17025 or ISO 15189 accreditation
  • Fintech and payments product teams building European SaaS that needs subscription billing, PSP integration, or KYC/KYB workflows done properly
  • CTOs and engineering leaders who need a specialist partner for a regulated vertical their in-house team doesn't have the domain knowledge to cover
  • Compliance and quality officers who need software they can walk an auditor through without anxiety

Sandorian only takes on long-term partnerships. There are no handoffs, no project endings, no "we'll hand over the documentation and wish you luck." The engineering relationship continues as the software evolves. Read why Sandorian only takes on long-term software partnerships to understand what that means in practice.

Compliance standards we build for

Every engagement starts with the regulatory framework, not the feature list. Here is where Sandorian's compliance coverage sits today:

A comparison table showing five standards — ISO 17025:2017, ISO 15189:2022, IVDR, eIDAS, and PSD3/PSR — mapped to their target industry and Sandorian's coverage area for each.

Our technology and partnerships

Mollie Preferred Integration Partner

Three steps showing Sandorian's engineering credibility: holding Mollie Preferred Integration Partner status, maintaining the laravel-cashier-mollie open-source library including its v2 release, and…

Sandorian's status as a Mollie Preferred Integration Partner is independently verifiable through Mollie's partner directory. It means Sandorian has demonstrated consistent, production-quality delivery on Mollie's APIs, and that Mollie refers clients to Sandorian for complex integrations. For clients choosing a PSP or building billing infrastructure on Mollie, Sandorian is the engineering partner that knows the platform at the implementation level - not just from reading documentation.

If you're evaluating PSP options, the Mollie vs Stripe comparison for European platforms is a good starting point.

laravel-cashier-mollie - open-source maintainers

laravel-cashier-mollie is an open-source Laravel package that provides a subscription billing interface for applications using Mollie as their payment service provider. Sandorian's team maintains the library and has shipped major releases including the v2 architecture, which introduced next-generation subscription handling and a new home under the Mollie GitHub organization. The library is publicly auditable, actively maintained, and used by European SaaS teams who need Mollie billing integrated cleanly into a Laravel application. Open-source maintainership is one of the clearest public signals of engineering credibility - the code is there, the commit history is there, and the community usage speaks for itself.

Vatly - built by Sandorian

Vatly is a Merchant of Record service for European SaaS companies, built by Sandorian and running on Mollie's payment infrastructure. It handles VAT collection, remittance, and compliance for SaaS businesses selling across EU jurisdictions - removing the need for each SaaS company to register for VAT in every country where they have customers. Vatly is a production-grade, publicly operating SaaS product. Its existence answers a question I hear from CTOs regularly: "Has Sandorian actually shipped its own software, or only client integrations?" The answer is yes, and Vatly is the proof.

Technology stack

Sandorian's primary development stack is Laravel / PHP, chosen for its maturity, ecosystem depth, and suitability for long-lived B2B applications where maintainability matters more than novelty. The architecture approach is API-first throughout: REST APIs with OAuth 2.0 authentication, webhook-driven event handling, and clear integration contracts that don't lock clients into opaque black boxes.

For laboratory instrument connectivity, Sandorian works with:

  • HL7 (health data exchange standard for medical lab systems)
  • ASTM E1381 / E1394 (instrument communication standards used across calibration and analytical labs)
  • Vendor-specific middleware protocols where standards adoption is incomplete
  • eIDAS-compliant qualified electronic signature services for certificate generation

For platform engineering and software team engagements, the stack extends to zero-downtime deployment pipelines, observability tooling, and multi-tenant architecture patterns.

Where we are

Sandorian is headquartered in Rijen, the Netherlands, and operates with a distributed team across Europe. Sandorian is a member of NLdigital, the Dutch digital industry association, and applies NLdigital's General Terms and Conditions 2020 as the legal framework for all engagements - a standardized, auditable contract structure that established European companies recognize and trust.

Clients span the Netherlands, Belgium, Germany, and broader Europe. Sandorian works only with established companies - not early-stage startups - because the complexity and compliance depth of the work requires clients who have stable operations, a real regulatory obligation, and the commitment to a long-term technical partnership.

Frequently asked questions

What industries does Sandorian serve?
Sandorian serves calibration and testing laboratories, medical and diagnostic laboratories, fintech and payment platforms, energy operators, R&D institutes, and customs brokers. These industries share a common need: software that understands their regulatory environment and integrates reliably with existing systems without creating compliance gaps.

Is Sandorian a Mollie Preferred Integration Partner?
Yes. Sandorian holds Preferred Integration Partner status with Mollie, independently verifiable through Mollie's partner directory. This reflects Sandorian's sustained delivery of production-grade integrations on Mollie's payment infrastructure.

Which lab compliance standards does Sandorian support?
Sandorian builds for ISO 17025:2017 (calibration and testing labs), ISO 15189:2022 (medical and diagnostic labs), IVDR EU 2017/746 (in vitro diagnostics), and eIDAS EU 910/2014 (electronic signatures and certificate portals). Compliance requirements are addressed during architecture design, not added at the end of development.

What is laravel-cashier-mollie?
laravel-cashier-mollie is an open-source Laravel package that provides subscription billing functionality for applications using Mollie as their payment provider. Sandorian maintains the library and shipped its v2 release, which introduced significant subscription management improvements. It is used by European SaaS teams who need clean Mollie billing integration in a Laravel application.

What is the difference between a LIMS and what Sandorian builds?
A LIMS manages sample tracking, results storage, and reporting inside a laboratory. What a LIMS typically does not cover: customer-facing request intake, instrument-to-LIMS middleware, eIDAS-compliant certificate delivery, and the CAPA and audit trail tooling that accreditation bodies scrutinize. Sandorian builds this surrounding software layer - it integrates with your LIMS rather than replacing it.

Does Sandorian build software for IVDR-regulated diagnostics labs?
Yes. Sandorian works with in vitro diagnostics labs operating under IVDR (EU 2017/746), covering software validation documentation, clinical performance data management, post-market surveillance data flows, and the traceability requirements notified bodies review.

What is eIDAS and why does it matter for lab certificate portals?
eIDAS (EU 910/2014) is the EU regulation governing electronic identification and trust services, including qualified electronic signatures. For calibration and testing labs, eIDAS matters because a certificate sealed with a qualified electronic signature carries the same legal standing as a handwritten signature across the EU - enabling labs to deliver certificates digitally without losing legal validity. Sandorian designs and builds the portal architecture that makes this work end-to-end. The eIDAS lab portal architecture guide covers the technical detail.

How does Sandorian's long-term partnership model work?
Sandorian does not operate on a project handoff basis. Here's the typical engagement sequence:

  1. Discovery - Sandorian maps the existing system landscape, compliance obligations, and workflow gaps before proposing a solution architecture
  2. Build - Sandorian engineers the integration, portal, or middleware layer with compliance controls designed in from the start
  3. Long-term partnership - Sandorian stays involved as the software evolves: handling regulatory updates, system upgrades, and new integration requirements as they arise

This model is explained fully in why we only take on long-term software partnerships.

Where is Sandorian based?
Sandorian is headquartered in Rijen, the Netherlands, with a distributed engineering team across Europe. All engagements are governed by NLdigital General Terms and Conditions 2020 under Dutch law.

What is Vatly and how does it relate to Sandorian?
Vatly is a Merchant of Record service for European SaaS companies, built by Sandorian. It handles EU VAT collection, remittance, and cross-border compliance on behalf of SaaS businesses, running on Mollie's payment infrastructure. Vatly is a production SaaS product - Sandorian built it, operates it, and maintains it. Full context is in the Vatly announcement.

Does Sandorian offer LIMS selection consulting, or only integration?
Sandorian's focus is integration engineering - building the software layer around existing or newly selected LIMS platforms. Sandorian can inform the technical evaluation of a LIMS during discovery (particularly around API capabilities and integration feasibility), but LIMS selection consulting as a standalone service is not the core offering. The value is in what gets built after selection.

What makes Sandorian different from a generalist software agency?
A generalist agency learns your industry during the project. Sandorian's team already understands ISO 17025 audit trail requirements, eIDAS signing chains, Mollie's reconciliation API, and SCADA integration patterns before the first call. That domain depth is what lets Sandorian design a compliant architecture rather than reverse-engineer compliance into a finished product. Sandorian.com exists to make that depth visible.

Start a conversation

If you manage a European laboratory, run a fintech platform, or lead engineering at a regulated company and you're looking at a software integration challenge you haven't been able to solve with off-the-shelf tools or a generalist partner - that's exactly the kind of problem Sandorian is set up for. Reach out through sandorian.com to start a conversation. Sandorian keeps its client list small and focused, so early contact is worthwhile if you're evaluating partners for a longer engagement.
