How to Build A Grocery App Like Happy Fresh

Grocery apps come with unique hurdles—the logistics of fresh goods, last-minute orders, and unnaturally picky consumers. However, consider grocery deliveries are worth $770.90 billion in revenue and growing at a CAGR of 11.81% and suddenly it’s worth the trouble!

For now, let’s focus on building the app first, using Happy Fresh as our reference material.

By the end of this guide, you will learn:

• Why HappyFresh is our benchmark for grocery delivery
• Key features of a grocery app
• Technology stack options for a grocery app
• Best practices for user engagement and customer loyalty
• Strategies for launching and marketing your grocery app

Let’s begin.

Why Is HappyFresh the Gold Standard for Grocery Apps?

Indonesian-based HappyFresh was founded in 2014 before expanding to Malaysia and Thailand via user-friendly interface design that catered to ts three primary user groups:

1. Convenient Grocery Shopping Experience

HappyFresh makes grocery shopping convenient and stress-free for consumers by offering:

• Wide Selection: Access to groceries from top retailers like AEON, Giant, Tesco, and more.
• Personalized Shopping Experience: Users can engage with personal shoppers for tailored advice, ensuring the freshest picks.
• Fast Delivery: Customers enjoy quick and reliable delivery options, with same-day or next-hour delivery services available.
• Seamless Payments: A range of secure payment methods, including credit cards and e-wallets, provide flexibility and convenience.

2. Professional Shoppers and Riders

For personal shoppers and riders, HappyFresh offers:

• Efficient Workflow: Professional shoppers are trained to select the freshest items, ensuring a quality shopping experience for consumers.
• Flexible Delivery: Riders ensure timely delivery, offering convenience for customers and a smooth operational flow for the service.
• Employment Opportunities: By joining HappyFresh, shoppers and riders can work flexibly and efficiently, delivering high-quality service without the need for upfront investments.

3. Merchants

HappyFresh simplifies online expansion for grocery merchants by:

• Low-Risk Entry: Merchants can join HappyFresh without any upfront costs, offering their products online in a matter of weeks.
• Increased Market Reach: Merchants gain exposure to a larger customer base, helping them increase sales and grow their business.

You’ll want to do the same with your grocery app.

Find Gaps in Happy Fresh Offerings

While HappyFresh is a good platform for grocery shopping, there are areas where it can be improved. 

While we couldn’t find anything wrong with the app itself, keep in mind that you are aiming to build a SaaS business, and historically, the Happy Fresh business model has failed.

HappyFresh expanded aggressively as apps funded by venture capital are prone to do. 

However, the company faced a high monthly burn rate and over US$97 million in debt. 

The world economy began to slow, and after seven years, HappyFresh Malaysia closed down on September 22, 2022.

So while there may not be anything wrong with the app itself, bear in mind you may not want to grow your grocery delivery business too quickly.
