How to Choose a Sitecore Development Agency
In This Article
Choosing a Sitecore development agency begins with understanding the delivery problem. An existing XP implementation needing maintenance, a new XM Cloud frontend and a migration with several enterprise integrations require different evidence and responsibilities. A list of product names is a useful starting point, but it is not an implementation plan.
Use this guide to prepare an agency comparison. For the service scope, see Sitecore CMS development services; this article focuses on the questions to ask before selecting a team.
Describe the platform and outcome
Share the platform version, frontend architecture, content model and hosting arrangement. Explain whether the goal is a new site, a migration, backlog delivery or ongoing support. List the systems that the platform depends on and the publishing problems your editors face.
Ask for an initial assessment that separates known requirements from unknown dependencies. This prevents a proposal for component development from being treated as a complete migration or support agreement.
How to Choose a Sitecore Development Agency
Choose a Sitecore development agency by matching evidence and delivery responsibilities to the actual platform and project. Ask for relevant implementation work, dependency assessment, QA, editorial testing and handover rather than inferring capability from product names or certification claims.
Check evidence relevant to the work
Request a walkthrough of a relevant implementation and the team's actual contribution. Ask about decisions, constraints, QA and handover. Public portfolio pages can help you choose topics to discuss, but they do not establish that every proposed engineer worked on every project.
- Who will lead the work, and what will each role own?
- Can the team explain content modelling and frontend integration decisions?
- How are code review, permissions and deployment managed?
- Can editors test preview, publishing and reusable components before launch?
- What evidence supports any claimed certification or project outcome?
Treat certifications as evidence to verify rather than something inferred from an agency's description. Agree which examples can be shared with your stakeholders and whether client information must remain confidential.
Discuss the scope and responsibilities for your project
Separate migration workstreams
Content transfer does not resolve presentation code, custom modules, integrations or analytics dependencies. Sitecore's official migration guidance explains that existing MVC solutions need conversion for XM Cloud's headless delivery model.
Ask for a dependency inventory covering components, forms, search, personalisation, identity and external systems. Require a plan for content, application changes, URL mapping and editor training. The XM Cloud development service is the relevant specialist journey when that platform is the target.
Choose the delivery model deliberately
An individual specialist can fit a bounded requirement when your team already owns planning, architecture, reviews and releases. A managed project team may be more suitable when those responsibilities also need to be supplied. Neither model removes the need for clear ownership on the client side.
Compare the Sitecore developer hiring service with a full implementation proposal. Agencies delivering under their own brand should also discuss confidentiality and client-contact boundaries with the white-label Sitecore partner service.
Ask for a testable delivery plan
A proposal should connect milestones to working outcomes. Include component behaviour, authoring, permissions, integrations, redirects, metadata and deployment checks. Ask who provides test data and who accepts the result. A demonstration of a homepage is insufficient evidence that every template and workflow is ready.
Agree how requirements are changed and how dependencies affect milestones. Ask which issues block release and how the team records unresolved risks. Written acceptance criteria make proposals easier to compare and reduce ambiguity at handover.
Define support separately from development
Determine who monitors the platform, investigates incidents, approves production changes and maintains integrations. Discuss support windows, escalation, included effort and exclusions in writing. A monthly developer package does not automatically establish a response-time commitment or round-the-clock coverage.
Use the Sitecore development support service for the ongoing journey. Keep emergency work, routine maintenance and feature development distinguishable in the proposal.
Prepare the enquiry checklist
Send the current architecture, project objective, required integrations, known pain points and launch constraints. Add the expected agency responsibilities, evidence you want to review and your handover needs. Ask for a scoped discovery recommendation when dependencies remain unclear.
Select the proposal that explains how your actual work will be delivered and accepted. A clear platform assessment, relevant evidence and explicit responsibilities are more useful than a broad promise to implement every Sitecore capability.

Frequently Asked Questions
What should I ask a Sitecore development agency first?
Describe the current platform, planned outcome, integrations and delivery constraints. Ask the agency which work is included, which assumptions need assessment and who owns testing, deployment and handover.
Should I use an agency team or a dedicated developer?
A dedicated developer can fit a defined skill gap when your team owns architecture and delivery. An agency team can be useful when the engagement also needs architecture, frontend work, QA, release coordination and support.
Is moving an MVC Sitecore site to XM Cloud a simple hosting change?
No. Existing MVC presentation and platform dependencies need assessment for a compatible headless implementation. Content transfer and application redevelopment are separate workstreams.
Does a developer package define production support coverage?
No. Confirm included hours, support responsibilities, availability windows and response arrangements separately in the written engagement. Do not infer them from a monthly developer amount.
