Sero vs Shopify POS

Different starting points

Shopify POS starts from the online store. As of 2026, per Shopify’s public site, it’s included with Shopify plans, with a POS Pro upgrade for more advanced retail features at each location. It’s a natural choice for brands whose business is mostly online and who want their shop counter to behave like another sales channel of the website.

SeroPOS starts from the counter. It’s a complete in-store system with inventory, purchasing, staff management and accounting, and its two-way Shopify sync means you can keep Shopify for the website while running the shop on SeroPOS. Products, prices and stock stay aligned in both directions, and online orders arrive in the SeroPOS queue.

When the store is more than retail

If you run a café in a bookshop, a bakery with packaged goods, a deli counter in a grocery store or a taproom that sells merchandise, you need restaurant tools as well as retail ones. SeroPOS includes floor plans, kitchen order tickets, a kitchen display, nested modifiers with upcharges and split bills in the same app as barcode retail.

Shopify POS is focused on retail. That’s fine for many brands, but for mixed businesses it can mean a second system for the food side, with its own menu, its own reports and its own end-of-day close. Running both sides in SeroPOS keeps one set of numbers and one staff login.

Inventory, payments and accounting

SeroPOS inventory includes purchase orders, suppliers, transfers between locations, lot and expiry tracking and recipes. For in-store cards you choose Global Payments, Moneris or Gravity Payments rather than being tied to one processor, and we offer to beat your current rate if you send us a statement from your existing provider.

Sales post to SeroBooks, which handles Canadian and US sales tax, inventory valuation and 160+ reports, or sync to QuickBooks Online and Xero on SeroPOS Pro. Amazon sellers can add SeroBooks for Amazon to account for settlements, fees and marketplace-facilitator tax, so every channel ends up in one ledger. Tax is recorded as a liability, never as revenue.

When Shopify POS may be the better fit

If your business is mainly online, you sell at pop-ups or run a single small shop, and you want one admin for everything, Shopify POS keeps life simple. Shopify’s app ecosystem is very large, Shopify Payments is quick to set up, and your staff work in the same interface you use to manage the website.

For brands that already depend heavily on Shopify apps for loyalty, subscriptions, reviews or marketing, staying inside Shopify can be less work than connecting another system. If your in-store needs are light and you don’t serve food, the extra depth of SeroPOS may simply not be necessary. Simplicity has real value.

Using both

Many retailers keep Shopify for the website and use SeroPOS at the counter. The two-way sync keeps catalogue, prices and stock aligned, online orders arrive in the SeroPOS queue for pickup or shipping, and ShipStation can handle labels. Your website stays exactly as it is, and only the in-store system changes.
