How Many Gigs Do I Need for a POS

How Many Gigs Do I Need for a POS

The question “how many gigs do I need for a POS?” is more common today than ever.

Retailers want a point-of-sale system that runs fast, stays reliable during peak hours, and doesn’t freeze when customers are lined up. Whether you’re opening a new store or updating old hardware, understanding memory requirements is one of the first steps.

As a retail POS consultant, my goal is to simplify this so you don’t overspend on hardware you don’t need or end up with a slow system that frustrates staff and customers.

Why POS Memory Matters

A POS system works like a small computer. Memory (RAM) affects:

  • How quickly the POS loads screens

  • How many apps it can run at once

  • How well it handles inventory tracking, reporting, and payment processing

  • Whether it lags during busy seasons

Modern POS software depends heavily on RAM because it uses cloud apps, browser-based dashboards, and payment integrations.

If you're looking for how many gigs do I need for a POS 2025, the answer is different from what stores used 5–10 years ago.

Minimum vs. Recommended RAM for a POS

Minimum RAM: 4GB

This is the lowest memory you should use in 2025. Basic POS systems can still run on 4GB, but you may notice slower loading times if:

  • You run multiple apps (inventory, CRM, accounting)

  • Your POS uses a browser interface

  • You process large product catalogs

  • You rely on real-time syncing

4GB works only for small retail setups with simple tasks.

Recommended RAM: 8GB

Most retailers today use 8GB RAM because it offers smoother performance and supports cloud-based POS software comfortably.

Why 8GB?

  • Faster product search

  • Quicker barcode scanning

  • No lag during checkout

  • Better for multi-register stores

  • Handles integrations (payment terminals, loyalty apps, reporting tools)

In short:


If you want the best balance of performance and cost, choose 8GB RAM.

High-Performance RAM - 16GB (Optional)

Consider 16GB only if your store:

  • Handles thousands of SKUs

  • Runs advanced reporting on-site

  • Uses POS + CCTV + accounting tools on the same terminal

  • Has a connected back-office workstation on the same device

For 90% of retailers, this is unnecessary—but for large operations, it improves speed significantly.

How POS Software Type Affects Memory Needs

1. Cloud POS Systems (Square, Shopify, Lightspeed)

These rely more on the internet than the device, but still benefit from memory.

Minimum: 4GB
Recommended: 8GB
Reason: Browsers like Chrome use heavy RAM.

2. Installed (Locally Run) POS Software

On-premise POS programs require more RAM because processing happens inside the device.

Minimum: 8GB
Recommended: 16GB for large setups

3. Tablet POS Systems (iPad / Android)

Tablets don’t use “gigs” the same way, but the equivalent is:

  • Entry-level: 3–4GB RAM

  • Recommended: 6–8GB

  • Best for heavy use: 8GB+

Does Storage (GB) Matter in a POS?

People often confuse RAM with storage.

Your POS also needs storage (GB), especially if you save:

Recommended POS Storage

  • 64GB for small stores

  • 128GB for mid-sized stores

  • 256GB for large retail brands

If your POS software relies heavily on offline mode, storage becomes even more important.

  • Offline backup

Best option: 16GB RAM, 256GB storage

How Many Gigs Do I Need for a POS Plan?

When choosing a POS “plan” (especially cloud POS), your hardware still gives your system its performance.

Your POS plan may include features like:

  • CRM

  • Reporting

  • Inventory management

  • Multi-store syncing

  • Loyalty programs

The more modules you use, the more RAM you need.

Simple POS Plan

4GB RAM is fine.

Advanced POS Plan

8GB RAM is ideal.

Enterprise POS Plan

16GB RAM recommended.
