Si Muddell's Review Sourced from Google
Fantastically positive and driven team who on every interaction you just know care deeply about a) what they do b) what they deliver and c) ultimately the experience the end user will have.Hugely impressed with their personal, creative and energy driven approach at the pitch stage, I commissioned 3SC to help us better scope an app. Their task was to take an in-house developed app prototype, and turn it into a fully fledged technical specification with user stories, MoSCoW prioritisation, costs, and an updated look and feel; all done with audience need at the heart.Myself and the wider team have nothing but very good things to say about 3SC. When reflecting on an agency to work with, loads say they can do it, some can actually do what they say they can do, even less do it in the spirit of real partnership and mutually respect/drive. 3SC do all of these excellently. I highly recommend them.

Headless CMS agencies help you design and implement a content platform and delivery stack that lets teams ship digital experiences faster, scale across channels, and integrate cleanly with your existing systems.
By decoupling the content platform from the front end, content teams can publish while developers ship front-end improvements on independent release cycles. In return, 69% of users report faster time-to-market and higher productivity.
With 98% of mobile app users expecting consistent UX and a 123% bounce rate for slow-loading mobile sites, headless CMS companies can help you deliver unified yet personalized user experiences. They achieve this by reusing structured content across touchpoints while maintaining centralized governance.
In fact, businesses switching to headless CMS report having 15% better UX and 14% improved performance.
With more localized and personalized user experiences, businesses are reporting higher conversion rates and ROI with their headless CMS systems. According to Gitnux, headless commerce adopters experience:
Moreover, IDC research found that omnichannel buyers spend 15%-20% more than those purchasing on a single channel.
The cost to build a digital solution with headless CMS architecture can range between $8,000 to over $500,000. The final billing will depend on scope, integrations, migration effort, number of channels, and build complexity.
Here are the hourly rates of headless CMS developers per region:
Based on these hourly rates, here are the approximate costs of each headless CMS project:
A headless CMS project can take 10-12 weeks for a small-scale project, like a multi-channel marketing website. However, more complex builds can take 12-20+ weeks, and enterprise replatforms can run 4-9 months.
The actual project timeline will depend on your project's complexity, core features and functions, integration and compliance requirements, and feedback loops. Here is an estimated timeline breakdown:
| Discovery and planning (2-4 weeks) | Stakeholder workshops to define business objectives, audiences, performance indicators, governance, and technical requirements. |
| Designing and prototyping (3-5 weeks) | Crafting the wireframes, architecture, design systems, and key components. |
| Content migration (2-10+ weeks, often in parallel with development) | Audit and migration plan, content cleanup, mapping, redirecting SEO, and validation. |
| Development and integration (4-8 weeks) | Content modeling, roles/permissions, environments, front-end build, and integrations (e.g., CRM and data analytics tools). |
| Testing and quality assurance (2-3 weeks) | Testing the website's performance, usability, accessibility, security, and reliability. |
| Launch (1-2 weeks) | Deploying the website to a live site and monitoring it for potential issues, so it can be resolved quickly. |

Headless CMS companies plan, implement, and operate a headless content management system (CMS), so teams can efficiently publish content across websites, apps, and other digital channels. Typical headless CMS development services include:
A headless CMS separates the content management backend from the frontend experiences. As such, content is delivered via APIs to any channel (websites, mobile apps, and IoT devices), so teams can reuse the same content across multiple experiences.
On the other hand, a traditional CMS has a unified back- and front-end (monolithic), meaning that there is a single interface that often comes in the form of a website. It can still power multiple channels, but doing so requires extensive tooling and customization.
Here are more details on their differences:
