The Home Screen

When you open SlonAxis, you see the Home screen where you can:

• Search for services or products by name
• Browse items in a grid display
• Add items to cart using +/- buttons
• View cart total with a counter

Adding Items to Your Cart

1. Find the item you want by scrolling or searching.
2. Tap the + button on the product card to add it.
3. Tap + again to increase quantity.
4. Tap - to decrease the quantity if needed.
5. Watch the cart counter at the bottom — it shows the total count of items.

Cart Button

At the bottom right, you'll see a floating button:

• Says "Cart" if empty
• Shows "Cart • N" if items are added (e.g., "Cart • 3" means 3 items)
• Tap it to go to your cart and checkout

Out of Stock Items

• Items marked "Out of Stock" cannot be added to cart
• The +/- buttons are disabled for these items

info

Services and Packages will always show as available, even if the products required to provide that service are out of stock. This is by design — managers can fulfill orders by sourcing the products later. Ask your manager before adding a service to cart if you're unsure about availability.

Cart Screen — Review & Edit

When you tap the Cart button, you see your shopping cart.

Each item shows:

• Product/service image, name, unit price, quantity, and line total
• Discounts applied banner (if any) showing how many offers and total savings

Edit Your Cart:

• Increase quantity: Tap + on the item
• Decrease quantity: Tap - on the item
• Remove item: Reduce quantity to 0

Customer Selection

Before checkout, you can add a customer (optional but recommended):

• If no customer selected: Treated as "Walk-in Customer" (anonymous). Tap "Add Customer" to link to a customer.
• If customer is selected: Tap customer name to Change Customer or Remove Customer.

Feature	Registered Customer	Walk-in Customer
Bill linked to profile	✅ Yes	❌ No
Payment recorded	✅ Yes	✅ Yes
Revenue counted	✅ Yes	✅ Yes

Always try to get customer details and link them to a profile. This helps managers understand repeat customers and apply loyalty rewards.

Checkout — Generate Bill

Once items are in cart and customer is selected:

1. Review items and verify quantities are correct.
2. Tap "Checkout" button at the bottom of the cart screen.
3. System validates all items, calculates subtotal, applies discounts and tax, and creates a bill.
4. Bill is generated with a unique Bill ID, items list, subtotal, discounts, tax, and total amount.

If checkout fails:

• ❌ Item is out of stock → Cannot proceed
• ❌ Item was deleted → Cannot proceed
• ❌ Cart is empty → Cannot proceed

Cart Locking

Once a bill is generated, your cart is LOCKED. You cannot edit items or create a new cart until payment is completed or cancelled. If you close the app, the locked cart persists — reopen the app and tap "Complete Payment" to resume.
