Ratings and reviews

• Sew EssentialStore migrationMay 13, 2026

  Rainy City migrated our website with over 20000 products from Magento to Shopify and we couldn't be happier with the end result. Not only that, the whole process was well managed, clearly communicated and the team were an absolute dream to work with every step of the way. We've updated our website with several different agencies over the years and it has never, ever been anywhere near this seamless. Every challenge or change we identified they resolved and accommodated with a positive can do attitude. They listened carefully to what we wanted and what was important to us, but they also advised and guided us with the latest recommendations in ecommerce too. We are continuing to work with them and hope to do so for many years to come. Thanks RCA you're the best!

• AvomiStore migrationJan 15, 2026

  We had an excellent experience working with Rainy City on Avomi. They’re proactive, super knowledgeable and genuinely care about getting the best outcome for your business rather than just delivering a “standard” Shopify build. We utilised an existing theme they built for us and the changes we needed were handled quickly. The site now looks premium, performs better and is far easier for us to manage day to day.

• NicstoreTheme customizationJan 15, 2026

  Rainy City have been a fantastic partner for Nic Store - a new brand for us. Utilising an existing theme they were incredibly easy to work with and kept everything clear and transparent throughout the project. 10/10 thank you!

• VapestoreStore migrationJan 15, 2026

  Rainy City were outstanding on the Vapestore project. Their team were responsive, organised, and genuinely felt like an extension of our own. They explained every step clearly, gave great recommendations (especially around our store migration), and delivered a site that looks modern and performs exactly how we wanted. The process was stress-free, and the end result is something we’re really proud of.

• CallingWebsite audit and optimization strategyNov 11, 2025

  Rainy City are a team that support solo-founded brands like mine to have the feeling of an in-house team. They bring experience, talented teams and opportunities to meet other founders through networking events and initiatives. I couldn't recommend them more. Moreover - they're great people.

• Thursday Boot CompanyTheme customizationNov 7, 2025

  We highly recommend Rainy City. Lovely people to work with and they do fantastic work.

• True ToysStore migrationOct 22, 2025

  Working with Rainy City Agency on our website migration from Magento to Shopify was an excellent experience from start to finish. We were able to complete a full migration in just two months thanks to a genuinely transparent and collaborative relationship throughout the project. The team’s communication, technical knowledge, and project management made the process smooth and efficient, while their collaborative approach to design ensured our ideas and feedback were always heard and translated into something even better than we’d envisioned. Any challenges that came up were handled quickly and openly, which built a lot of trust and confidence in their approach. We’re really happy with the end result — the site performs brilliantly, looks great, and gives us much more flexibility moving forward. We’ve since continued working with Rainy City on ongoing site optimisations, and I’d happily recommend them to anyone looking for a reliable and skilled Shopify agency.

• CrossflyStore build or redesignNov 23, 2021

  Rebecca, Dean and the Team were absolute Tigers at sticking to their task and were always on call whenever we needed them. I loved their commitment to getting the job done and nothing ever seemed too much for them to cope with. There is no doubt I would recommend them to build your Shopify platform. Duncan P.

• Sparkle In PinkOct 11, 2021

  Working with Rainy City has been amazing! They are very responsive and timely at getting things done. We have been around for 10 years and have worked with many developers over the years, and have had problem after problem with every company we've worked with. We finally found a dev team we can rely on, and it has been a game changer for our company! 10/10 recommend this team to anyone with Shopify theme development needs.
