The grocery ecommerce solution buyer’s guide (2026)

How FMCG & Grocery Retailers Choose the Right Platform, and Why Grocery-First Wins

Across Europe and globally, grocery retailers are now focused on scaling, optimising, and differentiating their online customer experience, while keeping operational complexity under control.

At the heart of this challenge sits the ecommerce digital storefront: the layer where customers browse, build baskets, engage with promotions, and place orders.

This guide is written for anyone who is involved in e-grocery customer-facing solutions, evaluating front-end platforms for grocery and FMCG retail. It explains:

• The main front-end platform options on the market

• The strengths and limitations of each provider

• How grocery-first platforms compare to generic and marketplace-led solutions

• Why some retailers ultimately choose Pickitoo
  

Why Grocery Front Ends Are Different

E-grocery customer-facing solutions have unique requirements that generic platforms struggle to support:

• High-frequency purchasing

• Large and complex baskets

• Temperature requirements for fresh, frozen, and deli items

• Different pricing - regular, promo, loyalty, location-based

• Store-based fulfilment constraints
  

When front ends are not designed with these realities in mind, retailers face:

• Long implementation timelines

• Pricy custom development

• Slow in-store fulfillment during peak hours

• Misalignment between IT, commercial, and operations teams
  

This is why platform choice matters more in e-grocery than in almost any other retail vertical.

Limitations
