How much does it cost to support and maintain my Magento 2 website?
Maintaining your Magento 2 store is essential to keep it secure, fast and performing at its best. At 5MS, support works as a flexible retainer where you pay for the hours you need, with packages to suit businesses of every size. Pricing stays transparent with no hidden costs. Download our price guide for current rates, or get in touch for a tailored quote.
What happens if I don't use all of my support hours?
It depends on the support package you choose. We structure plans around the level of cover you actually need, and we are clear from the start about how hours are tracked and what happens to any time you do not use. If you are unsure which package fits, get in touch and we will explain exactly how it works before you commit, no surprises.
Can you help me get the most out of Magento?
Yes. Getting the most out of Magento is exactly what we do. Beyond keeping your store secure and fast, we optimise performance, improve SEO and the on-site experience, advise on new features and integrations, and use analytics to find the changes that lift conversions. Think of us as a long-term growth partner, not just a maintenance team.
Do you work with businesses in Portsmouth?
Yes. We are a UK Magento agency serving Portsmouth and the wider Hampshire area, as well as brands across the country. Our UK-based team works with clients remotely and on-site as needed, giving Portsmouth businesses a full-service Magento partner of developers, project managers and marketing specialists, without compromise.
Are you a certified Magento agency?
Yes. 5MS is an official Adobe Solutions Partner with UK-based, certified Magento developers. We have worked with Magento since 2011, so you are getting a team with deep, proven experience across Magento development, support and optimisation.
Can you migrate our store or take over from another agency?
Yes, and we guarantee a smooth migration from your current Magento provider. We take over cleanly, keep what is working and put right what is not, with no disruption to your store or your customers. Protecting your search rankings through the move is built into how we plan every migration.
Do you offer flexible retainers or pay-as-you-go support?
Our support works as a flexible retainer where you pay for the hours you need, whether that is occasional fixes and one-off jobs or a set block of hours each month with priority, SLA-backed response. You can scale up or down as your needs change, and if you would rather we handle everything, our fully managed partnership covers support, security, SEO and ongoing improvements. Download our price guide for current rates.
Am I tied into a long contract?
No. We earn our place month to month. Our support is built to flex around your business, so you can move between paying for the hours you need, a retainer and a managed partnership as things change. We would rather keep you because the work speaks for itself than lock you into a contract you cannot leave.
How long does a Magento project take?
It depends on the scope. A focused improvement or a migration can take a few weeks, while a full new build or replatform takes longer. After our initial discovery and audit, we give you a clear roadmap with realistic timescales upfront, and our clients consistently tell us we are transparent about timing from the start.
Do you work with Adobe Commerce as well as Magento Open Source?
Yes. As an official Adobe Solutions Partner, we work across Magento Open Source and Adobe Commerce. Whether you are on Magento 2 today, planning a migration, or weighing up Adobe Commerce, our certified developers can advise on the right platform and version for your business and budget.
