How Shopify POS Works: The Complete Guide

Updated August 2026 with current hardware, pricing, and the POS Go retirement.

Shopify POS is a point-of-sale system that connects a physical store to a Shopify account, so in-person and online sales run on the same inventory, customer records, and reporting. It runs on iPhone, iPad, and Android through the Shopify POS app, and pairs with Shopify's own card readers and terminals.

It comes in two versions — POS Lite, included free with every Shopify plan, and POS Pro, an $89 per month per-location upgrade. Which one a store needs depends less on size than on whether it has staff, multiple locations, or inventory that moves between them.

This is the overview. Each section links to a deeper guide where there is one.

How Shopify POS works

The POS app installs on a phone or tablet and signs into the same Shopify admin that runs the online store. Products, prices, and stock levels are shared, so a sale rung up at the counter decrements the same inventory an online order would. Customer profiles and order history are shared too, which is what makes buy-online-pickup-in-store and in-store returns of online orders possible without manual reconciliation.

That shared data layer is the entire argument for Shopify POS over a standalone system. If your online store is already on Shopify, you are not integrating two systems — there is only one.

What it costs

Three separate costs, and merchants routinely budget for only the first.

The software. POS Lite is free with every Shopify plan. POS Pro is $89 per location per month.

Card processing. In-person rates depend on your Shopify plan: 2.6% + 10¢ on Basic, 2.5% + 10¢ on Grow, and 2.4% + 10¢ on Advanced. The flat 10¢ per transaction is the part people miss, and it matters enormously if your average order value is low. A cafe doing $10,000 a month in $6 tickets pays roughly $1,700 a year more in fees than a boutique doing the same revenue in $40 tickets.

Hardware. Anywhere from nothing to about $1,100 per counter. See below.

POS Lite vs POS Pro

The practical dividing line: a solo operator selling at markets or a single counter is well served by Lite. Once there are employees to hold accountable, stock moving between locations, or pickup orders to fulfill, Pro pays for itself quickly. The full POS Lite versus Pro breakdown covers the limits in detail.

Hardware

The lineup changed significantly in 2026. Shopify partnered with Verifone, and POS Go — the old all-in-one handheld — is being retired, with mobile selling ending May 26, 2027. Do not buy one.

Hardware compatibility varies by country and device generation, so confirm before buying. Our Shopify POS hardware guide covers what is worth buying, what to skip, and the full cost of ownership.

Setting up Shopify POS

Setup follows the same sequence in most stores:

1. Install the Shopify POS app and sign in to the Shopify account
2. Set the store location, currency, and tax settings in the admin
3. Confirm products and inventory are assigned to the retail location
4. Pair the card reader and any peripherals over Bluetooth or USB
5. Enable offline payments and set your transaction limits
6. Set up staff accounts and PINs, then run a test transaction

Most of the time is spent on inventory hygiene, not the app itself — products never assigned to a physical location will not appear on the register. Our card reader setup and troubleshooting guide covers pairing, and what to do when a reader drops mid-shift.

Payments and connectivity

Payments run through Shopify Payments where available, at card-present rates lower than the equivalent online rates. Cash, gift cards, store credit, and custom tender types are all supported — our guide to Shopify POS payment methods covers enabling each one.

On connectivity: Shopify POS can process card payments offline, but the feature is off by default and has to be enabled in advance, with per-transaction and per-device caps. If a payment declines once it uploads, the loss is yours. Tap to Pay does not work offline at all. This is the single most common gap between what merchants assume and how the system actually behaves — our offline mode guide walks through the setup and the risk.

Staff access and security

Every staff member gets a PIN that identifies them at the register, which is what makes sales attribution, void tracking, and refund permissions work. POS Pro extends this into full role-based permissions. As of June 2026, a centralized Devices view in admin lets you see every POS device across locations and remotely log out a lost or stolen unit. Our POS PIN code guide covers setting, resetting, and managing staff access.

Branding the customer-facing display

The screen a customer looks at while their payment processes is a brand touchpoint, and it is customizable. In Shopify admin, go to POS Channel settings and open the Display Editor. From there you can add a logo to the lock screen, apply brand colors across the interface, upload custom background images, and preview everything before publishing.

This matters most for pop-ups, markets, and temporary locations, where establishing recognition quickly is part of the job. Use the same colors and imagery as your online store so the experience reads as one brand rather than two.

Compliance in Germany and Austria

Shopify POS has built-in regulatory support for two European markets that require it. German merchants get KassenSichV compliance (the cash register security regulation), and Austrian merchants get RKSV, its Austrian equivalent. Both are integrated rather than requiring a third-party add-on.

The practical tooling that comes with it: Z-Reports for daily financial reconciliation, and Cash Book functionality for the record-keeping those regulations expect. If you operate in either market, verify your specific configuration rather than assuming defaults are correct — the system does the heavy lifting, but a local accountant should confirm your setup meets your own circumstances.

How Shopify POS compares

The honest summary: if the online store is already on Shopify, POS is the path of least resistance and the unified inventory is the reason. If a store is primarily in-person with no ecommerce ambitions, Square is often cheaper to start. If inventory complexity is the defining problem — thousands of SKUs, serialized items, deep purchase-order workflows — Lightspeed is stronger.

Frequently asked questions

How does Shopify POS work?

The Shopify POS app runs on a phone or tablet and signs into the same Shopify admin as your online store. Products, inventory, customers, and orders are shared, so an in-store sale updates the same stock an online order would. You pair a card reader over Bluetooth or USB to take payments, and everything reports through one dashboard.

Is Shopify POS free?

POS Lite is included with every Shopify plan at no extra cost. POS Pro is $89 per month per location. Card processing fees apply separately at in-person rates of 2.4% to 2.6% plus 10¢ per transaction, depending on your plan.

Do I need a Shopify online store to use Shopify POS?

A Shopify account is required, but the online storefront does not have to be active. Many retailers run POS with the online store password-protected or disabled entirely.

Can Shopify POS work without internet?

Partly, and better than most guides suggest. Cash and custom payment methods always work offline. Card payments also work offline, but only if you enabled offline payments in your admin beforehand and set transaction limits — and you carry the liability if one declines after it uploads. Tap to Pay is not supported offline. See the offline mode guide.

What hardware do I need?

At minimum, a way to take cards and a device to run the app — which can be as little as Tap to Pay on a phone you already own. A typical starting setup is a $49 Tap & Chip Reader with an iPad. Fixed counters are better served by the $349 POS Terminal.

Does Shopify POS support German and Austrian tax regulations?

Yes. KassenSichV compliance is built in for Germany and RKSV for Austria, along with Z-Reports for daily reconciliation and Cash Book record-keeping. No third-party add-on is needed, though you should verify your specific configuration with a local accountant.

How many registers can I run?

Unlimited, on both Lite and Pro. Pro is billed per location, not per register, so adding a second till at the same address does not increase the subscription.

The bottom line

For a store already selling on Shopify, POS removes the reconciliation problem that separate systems create — one inventory, one customer list, one set of numbers. Start on Lite, and move to Pro when staff management, multi-location stock, or local pickup become real operational needs rather than hypothetical ones.

Two things to get right early: skip POS Go given its 2027 end-of-life, and switch on offline payments before your first busy weekend rather than after it.
