Setting Up Your First Retail POS: A Complete Guide

Opening a new retail business is exciting — and overwhelming. Your POS system is the operational heart of your store, touching everything from sales and inventory to customer management and reporting. Getting it right from the start saves you headaches down the track.

This guide walks you through everything you need to set up a retail POS system in New Zealand, from choosing hardware to going live on day one.

Step 1: Define Your Requirements

Before you buy anything, answer these questions:

How many checkout points (terminals) do you need?
Do you need barcode scanning?
Will you accept cash, card, or both?
Do you need inventory management?
Will you have an online store that needs to sync with in-store stock?
Do you need loyalty or rewards features?
What’s your budget — both upfront and ongoing?

Write these down. They’ll guide every decision from here.

Step 2: Choose Your POS Software

Your POS software determines what your system can do. For New Zealand retail, popular options include:

Vend (now Lightspeed): Cloud-based, excellent inventory management, good for multi-store. NZ-developed.
Shopify POS: Great if you also sell online. Seamless sync between online and in-store.
Idealpos: Traditional on-premise system. Very robust, popular in NZ hospitality and retail.
Square: Simple to set up, good for small businesses. Free basic plan with transaction fees.

Most software providers offer free trials — take advantage of them. Test with your actual products and workflows before committing.

Step 3: Select Your Hardware

A typical retail POS hardware setup includes:

The Essentials

Terminal/display: A touchscreen tablet (iPad or Android) or a dedicated POS terminal. Dedicated terminals are more durable but more expensive.
Receipt printer: A thermal receipt printer like the Epson TM-T82III. Fast, quiet, and reliable. Budget around $400–$500.
EFTPOS terminal: For accepting card payments. Rent or purchase from a payment provider like Windcave or Verifone.

Highly Recommended

Barcode scanner: The Zebra DS2208 or Honeywell Voyager 1200g are excellent choices. Budget $200–$350. Essential if you sell barcoded products.
Cash drawer: A metal cash drawer that connects to your receipt printer (opens automatically with each cash sale). Budget $150–$250.

Nice to Have

Customer-facing display: Shows the customer what’s being rung up and the total.
Label printer: For printing price labels and barcode stickers.
Tablet stand: If using an iPad, a secure adjustable stand keeps it stable and accessible.

Step 4: Set Up Your Network

Your POS needs a reliable network connection. For cloud-based POS, this is critical — no internet means limited or no functionality (though most have an offline mode for emergencies).

Use a wired (Ethernet) connection for your primary terminal if possible — it’s more reliable than Wi-Fi.
Set up a dedicated network for your POS and EFTPOS equipment, separate from customer Wi-Fi.
Have a backup plan: a mobile hotspot or 4G failover router can keep you trading during internet outages.

Step 5: Configure Your Software

This is where the real work happens. You’ll need to:

Set up your product catalogue — names, descriptions, prices, categories, barcodes
Configure tax settings (15% GST for most NZ businesses)
Set up payment methods (cash, EFTPOS, credit card)
Configure receipt templates with your business name, address, and GST number
Set up user accounts for staff with appropriate permission levels
Import existing product data if migrating from another system

Tip: If you have more than 50 products, ask your POS provider about bulk import via CSV. Entering products one by one is tedious and error-prone.

Step 6: Integrate Payments

Connect your EFTPOS terminal to your POS software so transaction amounts flow automatically. This means:

Staff don’t manually key amounts into the EFTPOS terminal (reduces errors)
Transactions reconcile automatically at end of day
Faster checkout for customers

Your POS software provider can confirm which payment providers they support. In NZ, Windcave integration is the most common.

Step 7: Train Your Staff

Don’t skip this. Even the best POS system will cause problems if your staff don’t know how to use it. Cover:

Basic sales transactions (scan, total, payment)
Refunds and exchanges
Opening and closing procedures (cash count, end-of-day reports)
How to handle common issues (printer jams, payment declined, system errors)

Step 8: Go Live (and Have a Backup Plan)

On opening day, be prepared for things to not go perfectly. Keep your POS provider’s support number handy. Have a calculator and manual receipt book as emergency backup. Process a few test transactions before customers arrive.

After the first week, review your setup. Is the workflow smooth? Are there bottlenecks? Do you need to adjust your product categories or receipt layout? Small tweaks early on prevent bigger problems later.

Common Mistakes to Avoid

Buying the cheapest hardware: Budget gear fails faster and costs more in the long run. Buy business-grade equipment from trusted brands.
Not testing before going live: Run test transactions with real products and payment methods before opening.
Ignoring networking: A flaky Wi-Fi connection will bring your whole operation to a halt. Invest in reliable networking.
Skipping staff training: Untrained staff make more errors, slow down service, and get frustrated.
Forgetting about support: Make sure you have access to local support. When things break at 5pm on a Friday, overseas helpdesks won’t cut it.
