What Are The Must-Have Features For A Grocery App Development?

In order to enhance the user experience, the software solution should come with several striking features that are at par with the top grocery delivery apps. 


Interactive Home Page

Users will be provided with a list of stores based on their location, and products’ searches. They can see ‘recommended’ & ‘open’ stores, and can also create a list of their ‘favorite stores’. Special badges will reflect against stores that follow the highest safety standards. 

Explore Stores & Products

Users can search for a variety of products and/or for a particular store they want to shop from. The system search algorithm will return matching products along with the stores’ availability. They will also get options for a substitute product, in case the selected product runs out of stock. 

Lightning Fast Search

The software should leverage ElasticSearch to enable super-fast search and filtering from a huge catalog. This provides a seamless user experience, besides shortening the sales cycle. 

Advanced Filters

Users will get multiple filtering options. They can apply the same based on their preferences. All products search will be sorted out based on ratings & reviews, availability, price, etc. 

Detailed Product Description

Users will get a descriptive view of products. This will help them better understand the product attributes – price, color, manufacturer, etc. The PDP allows users to check which store is offering the lowest price on a product. 

Product Availability Notifications

As products will have specific inventories added on the CMS panel, users will be notified about the availability of a product, during checkout. Similar products can be generated using a machine learning algorithm, based on buying patterns of users. 

Multi-Vendor Cart

To enhance the user experience, the software should allow customers to shop & order from a variety of stores, at the same time! They can add or delete items, and can also view total savings on every purchase. Users can also schedule a preferred time for the delivery. 

Seamless Checkout Process

After confirming the order & delivery address, users can choose from multiple payment options (credit/debit cards, COD, app wallets) in our online grocery delivery app software. If a store does not deliver in a particular area/zone, users can either cancel the order or change the address. 

Real-Time Delivery Tracking

The real-time tracking will help users to know each detail- from the time the order gets picked, to the completion of the delivery. In case a product is unavailable, the picker/delivery agent will inform the users, and the latter can immediately opt for a substitute, or cancel the item. 

Order History

The whole list of past and present orders will be visible to users. Orders can be filtered based on several parameters (months, years). Orders that are purchased from multiple stores, will be tracked separately.

grocery delivery software- unique selling points


The functioning of the store app must be highly flexible and should allow configuration, based on several parameters.  

Home Page

The grocery store application is an excellent tool for store owners/ product sellers to manage and dispatch orders to customers. The home page shows a list of tabs where a new order; orders that are ready for pickup, checkout & delivery- all are displayed in an organized way. 

View All Order Details

As and when a new order arrives, the owner gets notified in the grocery delivery software. They can now see all necessary details- like the customer details, the contents of the order, the selected mode of payment, etc.

Assigning A Picker

After accepting the order, the store owner can either pick-up the items himself or assign a picker. Detailed order picking stages (‘order picked’, ’not picked yet’, ‘product substituted’, ‘product removed’) will be displayed in various tabs for faster updates. 

Suggestion Of Substitute Products

The picker or the store owner has the option to update the customer about products that are unavailable or out of stock. A substitute product will be suggested by the picker, and on approval by the customer, they can continue with the grocery shopping & delivery process.  

Bag Label Printing

During checkout, the cashier will generate a receipt after scanning all the items. The receipt must be uploaded to the app. The picker will then confirm the no. of bags, print labels for each bag, which will be tied to the order & scanned by the driver at the time of delivery. 

Pickup & Delivery

Once the shopping process ends, the store/freelance driver will update the customer about his estimated time of the final delivery. In case a driver isn’t assigned for the job, the store manager can manually assign a person from the store to deliver the groceries.

Multi-vendor grocery delivery app software should facilitate order delivery either via freelance drivers (ones who can pick-up items & deliver from multiple stores), or specific store drivers. 

Assignment Of Orders 

A store driver will be assigned the job directly, but freelance drivers will receive notifications on the app which they can accept or reject. The drivers will have the option to mark themselves available or unavailable as per their preference.  

Single Pickup – Multiple Deliveries 

Since drivers can deliver grocery orders at multiple addresses, they can provide updates both to the store owners/managers and the customers, all the same time! The real-time updates ensure seamless communication between drivers, store owners, and customers. 

Proof Of Pickup & Deliver

The driver has to scan the QR code for each bag before delivery. The grocery delivery will be considered complete only after he has taken the signature of the customer. In case of contactless delivery, the drivers can take snaps of the bag left at the doorstep, as a sign of proof. 

Reattempting Delivery Management 

The driver can reattempt for a delivery, in case the customer is unavailable. He is allowed to do the same for other reasons as well and has to provide valid reasons, in order to inform the system admin about the reattempt.
