IT Support for Perth
Retail Businesses

When your POS system goes down mid-Saturday trade, the cost is immediate and visible. We build IT around the uptime and payment security a Perth retailer actually needs.

Sound familiar?

Common IT Problems Perth Retailers Face

POS system down mid-Saturday trade with no way to take payment

No internet failover - a dropped connection stops trading entirely

Stock counts drifting out of sync between in-store and online

Payment network not properly isolated, creating unnecessary PCI DSS scope

Casual and seasonal staff access not provisioned or revoked consistently

No plan for what staff actually do during a system outage

We fix these - and prevent them from happening again.

What We Do

IT Services Built for Retail

POS & Payment System Support

We support Square, Lightspeed Retail, Impos, Shopify POS, and similar platforms - understanding the specific hardware and integration each one actually needs.

PCI-Compliant Network Segmentation

EFTPOS and card payment terminals kept on a separate, isolated network from staff and customer WiFi - both for security and PCI DSS compliance.

4G/5G Connectivity Failover

Automatic backup connectivity that takes over when the internet drops, so a dropped connection doesn't mean lost trade.

Stock & Inventory Integration

Reliable syncing between your POS, online store, and inventory systems, so stock counts don't drift out of sync until a physical count finds the problem.

Retail WiFi Design

Coverage planned properly for metal shelving, stockrooms, and awkward floor plans that a single router rarely handles well.

Backup & Downtime Planning

A tested backup and a clear plan for what staff do during an outage - a manual sales process, a backup terminal, an alternate connection - not an afterthought.

Recovery Time Matters More Than in a Typical Office

An office business with a system outage can often keep working around it for a few hours. A retailer with a POS outage during trading hours typically can't sell anything until it's fixed - so recovery time matters more than for most other business types.

A tested backup and a clear plan for what staff do during a system outage should be part of every retail IT setup, not an afterthought.

FAQs

Retail IT Questions, Answered

What POS platforms do you support?

Most Perth retailers run on Square, Lightspeed Retail, Impos (formerly Kounta), or Shopify POS. Each has different hardware requirements, offline capability, and integration options - we understand the specific platform, not just treat it as generic software.

Do we need PCI DSS compliance if we use a third-party terminal provider?

The scope is significantly reduced if you handle card data entirely through a third-party terminal provider rather than directly, but a properly segmented payment network is still the right approach either way, both for security and to keep your compliance obligations as simple as possible.

How much does connectivity failover actually cost?

A 4G/5G backup connection that automatically takes over during an outage is one of the highest-value, lowest-cost investments a retailer can make, especially compared to the cost of lost trade during even a single busy-period outage.

What should staff do if the POS system goes down mid-trade?

This should be a documented process, not improvised on the day - a manual sales process, a backup terminal, or a fallback connection, depending on your setup. We build this into every retail IT plan, alongside the tested backup that gets full systems back up properly afterward.

This guy really knows his craft. I have used Top Tier several times already. His expertise is extensive and fits in well with our Company's growth at this stage. Having Top Tier as a partner going forward is an insurance policy for our ever expanding IT requirements.

Couldn't recommend Top Tier Computing highly enough. They went above and beyond to help me sort out some IT issues with my business, even taking the time to assist me over the weekend while I was overseas. They were responsive, knowledgeable and made the whole process straightforward.
