Powering 30% Online Sales Growth
See how we contributed to the 30% YoY sales growth for the UK’s leading organic food brand through ecommerce consultancy, CRO, and subscriptions.
Biona is a family-owned, market-leading organic food company dedicated to providing high-quality organic food for everyone to share and enjoy. Their direct-to-consumer channel has become a key growth driver, but to unlock its full potential, Biona turned to our ecommerce consultancy expertise.
The Challenge
Despite strong brand equity and customer demand, Biona’s ecommerce site faced two key challenges:
Conversion & retention
Strong traffic volumes were not translating into optimised on-site conversion and repeat purchase.
Subscriptions & loyalty
No existing framework to encourage recurring revenue or deepen brand loyalty.
Biona needed a roadmap to strengthen their DTC channel, improve performance metrics, and create a long-term retention strategy.
Our Approach
Gravytrain partnered with Biona to deliver a consultancy-led programme of CRO and strategic ecommerce improvements, including:
CRO audit & testing via Visually, delivering data-backed recommendations and running structured experiments.
Shopify development to enrich the site’s user experience and optimise customer journeys.
Subscriptions implementation, introducing a recurring revenue model with 190 subscribers onboarded within months.
Loyalty programme refresh and evaluation of service providers for reviews to enhance retention.
SEO & CRO support to ensure scalable growth across acquisition and on-site conversion.
The Results
- 30% increase in sales YoY since consultancy began.
- 33% increase in traffic, driving stronger brand reach.
- 4% uplift in AOV, supporting higher customer spend.
- 190 active subscriptions live on site, establishing a new revenue stream.
- £20k+ assisted revenue from ongoing CRO tests run via Visually.
- Delivered strategic clarity on next steps for growth, including which areas of the business required review and optimisation.
Our work with Biona demonstrates how consultancy-first partnerships can translate into tangible growth for FMCG and food brands on Shopify. By combining CRO testing, UX improvements, and a clear retention strategy, Gravytrain has helped Biona build the foundations of a scalable DTC channel.
