Names like these, in green, are pages inside your ArmPOS shop. Sign in to your shop to open them.

By the end you will have added a customer, from the POS or with the full form, and know how to follow what they owe.

The walk-in customer

A new shop has one customer, walk-in-customer. It is the Default Customer in Settings › System Settings › Defaults, so every POS sale starts with it. Keep it for sales where you don't need to know who is buying.

Your customers

People › Customers lists them all, newest first, with their Phone, Email, loyalty Points, Credit Limit, Opening Balance, Total Sale Due (what they owe you) and Total Sell Return Due (what you owe them). Search, Filter, PDF and EXCEL are above the list.

People › Customers: Search, Filter, PDF, EXCEL, Import Customers and Create above a list of customers with their phone, email, points, credit limit, opening balance, total sale due and total sell return due.
Total Sale Due is what each customer still owes you.

Add a customer at the POS

  1. Click the Quick Add Customer icon in the POS top bar, or click Customer and then Quick Add Customer at the top of the list. F8 opens the same form.
  2. Enter the Customer Name. It is the only required field. Email, Phone, Country, City, Tax Number and Address are optional, and Is royalty eligible lets them collect loyalty points.
  3. Click Submit. The new customer is selected for the sale in progress.
The Quick Add Customer window: Customer Name with Daniel Okot, Email, Phone, Country, City, Tax Number, Address, the Is royalty eligible box, and Cancel and Submit.
Quick Add needs only a name. The customer is chosen for the sale straight away.

Quick Add Customer shows while it is switched on in POS Settings. It is on in a new shop.

Add a customer with every detail

  1. Open People › Customers and click Create.
  2. Fill the required fields: First name, Last name, Username and Email. Username is the name the POS and the receipts show. Two customers can't share an email, and neither can a customer and an online store account.
  3. Add what else you know. Phone, Country, City, State, Zip, Tax Number and Address.
  4. Set the money fields if they apply. Opening Balance (Previous Dues) is what the customer owed you before ArmPOS. Credit Limit is the most they may owe, and 0 means no limit.
  5. Tick Is royalty eligible if they should earn loyalty points on their purchases.
  6. Click Submit. You land back on the list.
The Create customer form filled for Agnes Nankya: first and last name, username, email, phone, country Uganda, city Kampala, a Credit Limit of 200, an address, and Is royalty eligible ticked.
Fields marked * are required. A Credit Limit of 0 means no limit.

What a customer owes

When a customer pays less than the total, the rest stays on the sale as due, and Total Sale Due shows it. Each customer's menu, the button at the start of their row, has:

  • Customer Ledger: their sales, payments, returns and quotations, with what is due.
  • pay all sell due at a time: one payment for everything they owe. It pays the opening balance first, then the sales.
  • pay all sell return due at a time: one payment for every return you still owe them. It shows only when you owe them something.
  • Customer Details, Edit Customer and Delete Customer.
  • Adjust Customer Points and Adjust Opening Balance.
  • Portal Client: their access to the customer portal.
A customer's menu: Customer Ledger, pay all sell due at a time, Customer Details, Adjust Customer Points, Adjust Opening Balance, Portal Client, Edit Customer and Delete Customer.
Everything about one customer starts from their menu.

A Credit Limit above 0 is checked at the POS. A sale that would take what the customer owes above it is refused.
