Growth & Maintenance Retainer UK
Hiring a UK developer costs £50,000–£80,000 per year before National Insurance, benefits, and management overhead. A London agency retainer starts at £4,000/month for a fraction of the output. Neither option makes sense for a scaling startup or a D2C brand that needs continuous technical progress without the bloat. Our Growth and Maintenance Retainer gives UK businesses a dedicated 12-person engineering team — Shopify developers, Next.js engineers, AI automation specialists — at a flat monthly rate that does not require a full-time headcount commitment. You get the output of a development team without the HR overhead. This is not a support ticket system. Every retainer client gets a dedicated project manager in ClickUp, weekly sprint updates, and direct access to the engineers building their product. We handle Shopify theme updates, new feature development, AI automation builds, CRO iterations, and infrastructure maintenance — whatever your growth stage requires. We have been doing this for D2C brands and growth-stage businesses across India and the GCC. The UK market needs the same thing: a technical partner who shows up every month, knows your stack, and moves things forward — without the invoice anxiety of hourly billing. As a DPIIT-recognised startup with AWS Partner and Official Shopify Partner status, we have the technical credentials and the infrastructure access to support UK businesses properly. Our engineers are not junior freelancers — they are the same team who delivered +41% mobile conversion for FloraSoul India and saved Bandbox 130 hours per month through AI automation.

FloraSoul India
100x Revenue growth over 4 years₹1Cr+ From ₹1L to ₹1Cr+ annual revenue+340% Organic traffic increase (Year 1)1.4s Average page load time
FloraSoul India, an Ayurvedic skincare brand founded by Garima Ahuja and Aankush Nagpal, had a vision to bring traditional Indian wellness wisdom to modern consumers. But their digital journey was anything but smooth. Their original website was built on WordPress by two freelancers who took their money and disappeared midway — leaving behind a broken, unusable storefront. The site suffered from constant downtime, painfully slow page loads, and a checkout experience that actively drove customers away. With practically zero revenue from their online channel and growing frustration, FloraSoul was on the verge of abandoning e-commerce altogether. When they reached out to us, they needed more than just a website. They needed a technology partner they could actually trust — one that would deliver on time, on budget, and stick around after launch.
Case studyZevarly
+280% Organic traffic growth (6 months)+45% Average order value increase+33% Repeat purchase rate1.6s Average page load time
Zevarly, a Kolkata-based fashion jewellery brand run by Mukesh Sethiya from the heart of Burrabazar, had built a loyal offline following through wholesale channels. But the brand had zero digital presence — no online store, no product catalogue, and no way to reach the growing wave of women shopping for jewellery online. The challenge was significant: fashion jewellery is one of the most competitive e-commerce categories in India. Customers can't touch or try on products, so every element of the online experience — from product photography presentation to zoom-enabled detail views — needs to build trust and desire simultaneously. Zevarly's product range spans hundreds of SKUs across gold-plated, silver-plated, and American Diamond collections, including bridal sets that need to feel premium even through a screen. Their competitors were already established on Shopify with polished stores, influencer partnerships, and strong Instagram presences. Zevarly needed more than just a website — they needed a complete digital commerce strategy that could compete from day one, with smart navigation for a large catalogue and pricing strategies that encouraged bulk purchases.
Case studyClient stories
What our clients say
Honest words from people who've been through the process. No stock photos, no made-up companies.
“When two freelancers ran away with our money, we had lost all trust in agencies. Innovatrix didn't just rebuild our store — they rebuilt our confidence. Four years later, we've gone from one lakh to over one crore in revenue. They're not our vendor, they're our technology partner.”
G
Garima Ahuja
Co-founder, FloraSoul India
“We had jewellery but no digital presence. Innovatrix gave us a Shopify store that actually feels like walking into a jewellery showroom. The tiered discounts and WhatsApp integration alone doubled our repeat customers. We went from zero online orders to processing 50+ orders a day within four months.”
M
Mukesh Sethiya
Founder, Zevarly
“Before this system, our team was glued to their phones all day just answering the same questions over and over. Now those hours are back, and our customers actually get faster responses than when we were doing it manually. Rishabh and his team understood our operations deeply before writing a single line of code.”
