Shopify POS earns its place when the online store is the business and the shop is a second way to sell the same catalog. Merchants start looking elsewhere when that stops being true: the physical store grows faster than the website, inventory work outgrows a web-first catalog, or a payments relationship pulls them toward a provider. Each alternative below answers one of those shifts, and the order reflects which shift we expect to be most common.

Where to go, in order

  1. Square, when in-person selling now leads. An integrated register, payments and hardware ecosystem built for small merchants.
  2. Lightspeed, when stock is the job. Deeper inventory and location workflows for retailers with transfers, counts and purchasing.
  3. Clover, when you buy through a provider. Hardware-led POS sold and serviced through merchant-service channels.

Why Square leads

Picture a boutique that opened online, signed a lease, and finds two years later that the counter carries the business. At that point the owner wants a register the weekend staff can learn quickly, with payments and devices from one company. One company for all three is Square's positioning; how fast your staff learn it is a demo check, so have a weekend employee ring a sale and a return in the trial.

The catch is the website. A Square Community moderator stated in 2025 that Square does not integrate with Shopify. Keeping the Shopify store and moving the counter to Square therefore means two catalogs and two stock counts, unless a third-party connector you have vetted closes the gap. The cleaner version of this move is a merchant whose web sales are small enough to rebuild elsewhere or retire.

When Lightspeed is the better move

Lightspeed is the alternative that does not force a choice between store and website. Its Retail (X-Series) help center documents a Shopify integration that treats Retail POS as the system of record and shares products, inventory, customers and sales with Shopify. The stated limits are worth reading before you plan anything: updates made in Shopify may be overwritten or cause sync issues, Shopify product images do not sync to Retail POS, products can no longer be sold only on Shopify, and barcodes sync once at setup unless Support enables two-way syncing. A retailer who wants the shop to own the catalog and accepts those terms gets deeper stock tools while keeping the web storefront.

When Clover is the better move

A merchant whose bank or local processor offers installed and serviced hardware may prefer Clover, which is positioned for that channel. The question is the same as with any Clover offer: will the provider put processing, device ownership, app support and termination in writing? Clover is a weak fit if the website still matters, because this guide has no source describing a Clover connection to Shopify.

Count the accounting change too

Xero's own integration syncs Shopify sales, payouts, fees and taxes, including Shopify POS sales, as daily summaries or individual transactions. Moving the counter off Shopify POS while keeping the store means in-person sales arrive in the books by a different route. Ask your bookkeeper which route they will use for the new register before the switch.

When to stay on Shopify POS

Stay if the website still drives most revenue, products and customers are shared across both channels, and transfers between locations are occasional. Shopify POS is doing the one job it is best placed for, and none of the alternatives here is positioned around that shared catalog the way Shopify POS is.
