A grocery delivery app differs from a normal store in three ways: thousands of items whose availability must stay current, products sold by weight whose price changes after picking, and substitutions when an item runs out. Build it with an organized catalog, a picker app for staff, delivery slots with set capacity, and payment by mada, Apple Pay or cash on delivery. In Fanann you describe it and it builds the database and admin panel too.

How do you build a grocery delivery app? The short answer
A grocery delivery app lets your customers browse your store's items, order, pay and choose a delivery time, while a staff member picks the order from the shelves and a driver delivers it. With the Fanann Agent you describe your store, departments, delivery and payment, and it builds the customer app, picker app, admin panel and database. Start with the neighborhood around your store.
Why your own app if you are already on delivery apps? Aggregators like HungerStation, Jahez, Keeta and Mrsool bring new customers, but take a commission and keep the customer relationship. Your own app serves your regulars: you know what they buy, send them offers directly and build real loyalty. Many stores do both.
- Customer data and purchase history are yours
- Offers and loyalty fully under your control
- No per-order commission, but you run delivery and marketing
- Ideal for regulars and big weekly baskets
- Access to new customers from day one
- A ready delivery fleet in many cities
- Commission on orders and platform rules
- Good for quick small orders and discovery
What features does a supermarket app need?
| Feature | What it does | Priority |
|---|---|---|
| Catalog | Departments and items with photos and prices; Arabic and English search that tolerates typos | Version one |
| Availability | Hide out-of-stock items automatically; update from POS or a daily file | Version one |
| Weighted items | Produce and meat by kilo or piece with an estimated price | Version one |
| Substitutions | Per item: similar substitute, call me, or remove | Version one |
| Delivery slots | Slots with capacity; express for small orders if possible | Version one |
| Payment | mada, Apple Pay, cards and cash on delivery | Version one |
| Saved basket | A 'monthly groceries' list reordered in one tap | Later |
| Offers and loyalty | Weekly deals, coupons, points | Later |
Catalog and stock: keeping thousands of items current
The top frustration with grocery apps is ordering an item only to learn it is unavailable. Make availability a priority from day one. The core data in plain words:
- Departments: produce, dairy, bakery, meat, frozen, cleaning and so on, with display order.
- Items: Arabic and English name, brand, size, photo, price, barcode, sold by piece or kilo.
- Stock: available quantity, plus a threshold that hides an item before it truly runs out.
- Orders and lines: requested quantity, picked quantity, actual weight, and any substitute.
- Delivery slots: a maximum capacity per zone and slot.
Three ways to keep availability current
- 1Connect to your POS
Best if your system offers an API, so stock updates automatically. Ask Fanann for it and share your system's documentation.
- 2A daily file
Export Excel or CSV from your system each morning and upload it in the admin panel to update quantities and prices.
- 3Update while picking
When a picker taps 'unavailable', the item is hidden for everyone else instantly.
If you also want full stock control for your store or warehouse, read build an inventory management app.
Picking, weights and substitutions: what happens in the store
The picker app is the screen your staff use walking the aisles. It sorts the order by department to cut walking, lets them scan barcodes to confirm the item, and records actual weight for items sold by the kilo.
| Situation | How the app handles it |
|---|---|
| Weighted item | Estimated price at order; picker enters actual weight, the amount adjusts and the customer is told |
| Out of stock, customer chose substitute | The app suggests similar items of similar size and price; the customer is notified |
| Out of stock, customer chose 'call me' | A quick call or WhatsApp button, with the decision recorded |
| Out of stock, customer chose 'remove' | Removed and deducted automatically |
| Chilled and frozen | Picked last and labeled on the bag so the driver keeps them cold |
Who does what: roles in the store
- Picker: sees only assigned orders, picks, enters weights and marks items unavailable; no revenue access.
- Driver: sees ready orders and addresses, confirms delivery and cash collection.
- Branch manager: manages items, prices and slots, and follows late orders and complaints.
- Owner: every branch, sale, offer and report.
Ask for these permissions to be enforced in the database itself, not just by hiding buttons, and for a log of who changed a price or cancelled an order, and when.
Delivery and payment: slots, zones and mada
Split delivery into slots with capacity matched to your pickers and drivers. Add a minimum order and a delivery fee, and consider free delivery above a set amount to encourage bigger baskets. Draw coverage zones on a map and use the National Address to reduce lost drivers. See maps and delivery zones.
For payment, connect local payments: mada, Apple Pay and cards, plus cash on delivery for those who prefer it. Many grocery customers like paying on delivery, especially with weighted items, so read cash on delivery vs online payment before deciding.
Seasons that need preparation
- Before Ramadan: ready-made Ramadan baskets, much higher demand, and pre-iftar slots that fill fast.
- Eid: meat, sweets and hospitality items, with an early order cutoff before Eid day.
- Start of the month: many families order monthly groceries after payday; prepare capacity and offers.
- Back to school: snacks and lunchbox supplies.
Build it with Fanann: a ready prompt
Paste this into Fanann and adjust departments, neighborhoods and prices. Ask for the plan first, then upload your item file.
Build a supermarket app called 'Hai Groceries', Arabic first with English. Login by phone with OTP. A catalog of departments and items (Arabic and English name, brand, size, photo, price in SAR, barcode, sold by piece or kilo), with items, quantities and prices imported from a daily Excel file in the admin panel. Arabic and English search that tolerates typos and ranks best-sellers first. Hide an item automatically when stock reaches a threshold. Each basket item has an out-of-stock choice: similar substitute, call me, or remove. Two-hour delivery slots each with capacity, coverage zones on a map, a minimum order and free delivery above an amount I set. Payment by mada, Apple Pay and cards or cash on delivery, with an e-invoice including VAT. A picker app: order sorted by department, barcode scanning, actual weight entry, an 'unavailable' button that hides the item and applies the customer's choice, then adjusts the amount and notifies the customer. A driver app with tasks, address and call. A saved 'monthly groceries' basket reordered in one tap. Admin: orders by status, most frequently out-of-stock items, daily sales, offers and coupons. Show me the plan and tables before building.

Launch checklist and common mistakes
- 1Start with best-sellers
300 to 500 items with clear photos beat 5,000 items without.
- 2Run ten real orders
From staff and family, including weighted and out-of-stock items; time the picking.
- 3Set capacity
How many orders can a picker handle per hour? Size slots accordingly.
- 4Promote in store
A QR sticker at the till and on bags, with a first-order discount.
- 5Review weekly
Most out-of-stock items, complaints and average delivery time.
Key takeaways
- Keeping availability current is the biggest challenge; link it to your POS or a daily file.
- Weighted products need an estimated price, then an adjustment after weighing, with the customer informed.
- Ask customers upfront what to do if an item is out: substitute, call me, or remove.
- Delivery slots with capacity stop you promising what you cannot deliver.
- A saved 'monthly basket' makes reordering one tap and drives repeat orders.
