The UK Magento agency market ranges from dedicated platform specialists with decades of experience to generalist web development shops that list Magento among a dozen other technologies. The difference matters considerably when a business is committing to a platform that will underpin its e-commerce operations for years. Asking the right questions during the selection process separates agencies that genuinely understand Magento Open Source from those that will learn on the client’s budget.
1. Are You an Adobe Solution Partner?
Adobe’s Solution Partner programme formally recognises agencies that have demonstrated Magento expertise through certified developers, client project volume, and ongoing training requirements. Partner status at Silver level or above is a meaningful signal: it indicates that the agency has made a sustained investment in the platform and is held to Adobe’s standards for technical competence.
Accentika holds Adobe Silver Solution Partner status, an accreditation that reflects over two decades of continuous Magento practice.
2. How Long Have You Been Working with Magento?
Magento has a long history. The platform launched in 2008, and the cumulative knowledge built up over that time, covering migrations between versions, the transition from Magento 1 to Magento 2, integration patterns, performance characteristics, and security vulnerabilities, is not something that can be acquired quickly. An agency that started working with Magento in the last two or three years will not have encountered the range of scenarios that a longer-established practice will have navigated.
Relevant experience is not just about years on the platform: it is about the variety of clients, project types, and integration challenges that have been encountered and resolved.
3. What Does Your Discovery Process Look Like?
A credible Magento agency will invest time in understanding a business before proposing a solution. The discovery process should cover existing platform limitations and pain points, integration requirements with ERP, CRM, and fulfilment systems, performance baselines and targets, and the specific business objectives the new or improved store is intended to serve.
An agency that jumps straight to a proposal without a meaningful discovery phase is either cutting corners or does not have the expertise to know what questions to ask. Both are warning signs.
4. Can You Demonstrate Integration Experience?
For most businesses, the Magento store does not operate in isolation. It connects to an ERP for stock and order data, a CRM for customer records, possibly a marketplace management tool, and in some cases an EPOS system or a B2B procurement platform. The ability to build and maintain these integrations reliably is what separates a Magento agency from a theme customisation shop.
Ask specifically about the integrations they have delivered: which systems, what data flows, how errors and failures are handled, and how the integrations are monitored in production. Accentika’s integration practice covers Sage, EPOS and Sage combined environments, Khaos Control, Punchout procurement, and multichannel marketplace management.
5. How Do You Approach Custom Development?
Magento Open Source is a mature, extensible platform with a well-defined architecture for custom development. Custom functionality should be built as properly scoped modules that follow Magento’s event-observer pattern and dependency injection framework, not as core file modifications that will break on every upgrade.
Ask how the agency handles custom development: whether code is version-controlled and how custom modules are maintained across Magento version upgrades. An agency that cannot answer these questions clearly is likely to produce technical debt that the client will pay to resolve later. Accentika’s custom plugin development practice follows Magento’s module standards throughout.
6. What Does Post-Launch Support Look Like?
A Magento store requires ongoing attention after launch: security patches, Magento version updates, performance monitoring, integration maintenance, and the continuous stream of smaller improvements that any live e-commerce business generates. An agency that focuses solely on project delivery and does not offer structured post-launch support leaves clients exposed.
Ask about response time commitments for critical issues, how security patches are managed, and whether the agency offers a proactive service that monitors and maintains the store, rather than simply reacting to reported problems. Accentika’s support and maintenance service is designed precisely around these needs.
7. Who Will Actually Work on the Project?
Some agencies present senior developers during the sales process but deliver projects using junior staff. This is particularly relevant for technically complex Magento work where experience makes a material difference to both the quality of the output and the efficiency of delivery.
Ask who specifically will be working on the project, what their Magento experience is, and if you can talk to them directly. The answer should be clear and specific. If it is vague, that is informative in itself.
Making the Decision
A Magento agency relationship typically lasts for years rather than months. The initial build or migration is only the beginning: the ongoing development, integration maintenance, and platform management that follow are where the quality of the agency relationship is most felt. Choosing well at the outset avoids the disruption and cost of switching agencies mid-programme.
