How to Use the POS

This is a step-by-step tutorial for using the POS system at Muse & Co. Whether it is your first shift or you need a refresher, this page walks through every action you will need to take -- from ringing up a drink to processing a refund.

Logging In

1. Open a browser on the register tablet (or any device).
2. Go to staff.ncmuse.co.
3. Log in with your staff portal credentials.
4. Navigate to the POS page.

You will see the main POS screen with category tiles on the left and an order cart on the right.

First Time Logging In?

Your credentials are the same ones you use for the staff portal. If you have not received them yet or cannot log in, ask your shift lead or email hello@ncmuse.co.

Taking an Order

Step 1: Tap a Category

The main screen shows color-coded category tiles. Tap the one that matches what the customer wants:

Category	Color	Examples
Coffee	Amber	Latte, Mocha, Drip Coffee
Boba	Purple	Classic Milk Tea, Taro, Matcha
Milk Tea	Pink	Thai Milk Tea, Honeydew
Fruit Tea	Orange	Mango, Passion Fruit, Peach
Snacks	Red	Packaged snacks and light bites
Seasonal	Blue	Limited-time specials
Workshops	Indigo	Sit and Paint, Paint & Boba

Step 2: Tap the Drink

After selecting a category, you will see a list of items in that category. Tap the one the customer ordered. For example, if they want a Classic Milk Tea, tap Boba then tap Classic Milk Tea.

Step 3: Customize

A customization screen appears after selecting an item. Set the following based on what the customer requested:

Sweetness:

Option	When to Select
100%	Default -- full sweetness
75%	Slightly less sweet
50%	Half sweet
25%	Lightly sweet
0%	No added sweetness

Ice Level:

Option	When to Select
Regular	Default -- standard ice
Less Ice	Customer wants less ice
No Ice	Customer wants no ice

If the customer did not specify a preference, leave it at the defaults (100% sweetness, regular ice).

Step 4: Add Toppings

If the customer wants toppings, tap each one from the toppings section. Each topping is added individually:

Topping	Price
Boba (tapioca pearls)	$0.50
Popping boba	$0.75
Jelly	$0.50
Pudding	$0.75
Other toppings	$0.50 -- $1.00

You can add multiple toppings to a single drink.

Step 5: Add to Cart

Tap Add to Cart. The item appears in the order summary on the right side of the screen, showing the drink name, customizations, toppings, and price.

If the customer is ordering multiple items, go back to Step 1 and repeat for each item. All items accumulate in the cart.

Adjusting Quantity

If a customer wants two of the same drink with the same customizations, you can adjust the quantity in the cart instead of adding the item twice. Tap the item in the cart and change the quantity.

Step 6: Review the Cart

Before checking out, review the cart with the customer. Read back:

• Each item and its customizations
• The total price

"That's a Classic Milk Tea, 75% sweet with boba, and a Taro Milk Tea regular -- $13.48 total. Sound right?"

Step 7: Tap Checkout

Once confirmed, tap Checkout. The payment screen appears.

Step 8: Select Payment Method

Method	What to Do
Card	Tap Card. The customer taps, inserts, or swipes their card on the reader.
Apple Pay / Google Pay	Tap Card. The customer holds their device near the reader. Stripe handles it the same as a card tap.
Cash	Tap Cash. Enter the amount the customer handed you. The POS calculates and displays the change to give back.

Step 9: Order Complete

Once payment is processed:

• A confirmation appears on screen.
• The order label prints automatically on the Brother label printer.
• Grab the label, attach it to a cup, and start making the drink (or hand it off to whoever is on drink prep).
• When the drink is ready, call the customer's name.

Voiding an Order

If you need to cancel an order that has already been placed (wrong item, customer changed their mind, duplicate order):

1. Go to the Order List in the POS.
2. Find the order you need to cancel.
3. Tap the order to open it.
4. Tap Void.
5. Confirm the void.

Voiding vs. Refunding

Void is for orders that have not been fulfilled yet -- the drink was never made. Refund is for orders where the customer already received their drink but there is an issue. Use the right one for the situation.

Processing a Refund

If a customer needs a refund (drink was wrong and they do not want a remake, or another qualifying reason):

1. Go to the Order List in the POS.
2. Find the order.
3. Tap the order to open it.
4. Tap Refund.
5. Select the specific items to refund (you can refund individual items without refunding the entire order).
6. Confirm the refund.

The refund is processed back to the original payment method. For card payments, it goes back to their card automatically. For cash payments, give the refund amount from the register.

When to Refund

Refunds should be offered when a remake will not solve the problem -- the customer is leaving, they do not want a replacement, or the issue is not drink-related (like being charged for an item they did not order). When in doubt, check with your shift lead.

Quick Reference

Action	Where	Steps
New order	POS main screen	Category > Item > Customize > Cart > Checkout
Add topping	Customization screen	Tap each topping after selecting the drink
Adjust quantity	Cart (right side)	Tap item in cart, change qty

Troubleshooting

Problem	Solution
POS page is frozen or unresponsive	Refresh the browser. Completed orders are saved, but your current cart may clear.
Label did not print	Check that the Brother printer is on and has paper. Green light = ready, red light = issue. See Label Printer.
Wrong item in the cart	Tap the item in the cart and remove it, then add the correct item.
Payment declined	Ask the customer to try another card or payment method. Do not share details about why it declined.
Cannot log in	Try refreshing the page. If that does not work, ask your shift lead or email hello@ncmuse.co.
