Three decisions people mix together
Keep both
In-person sales stay on Square: the stand, the readers, the staff login, the locations you already run. Online sales move to Shopify, or stay on Shopify if you are already there. Between them, SquareFloww syncs the shared records.
You are not “half migrated.” You are running two systems on purpose, with a map between them. That is a normal retail shape: the floor tool people know, and the ecommerce tool with the theme and app ecosystem you want.
Migrate the website once
A different path is leaving Square Online. Shopify’s own docs walk through moving a catalog from Square’s website into Shopify. That project ends. After it, Square Online is not your storefront. Your POS might still be Square. If it is, you are back to “keep both,” and you still need an ongoing sync or the new Shopify catalog will drift from the register.
If the search was “migrate Square to Shopify,” write down which thing is moving: the website, the POS, or both. Only the website has to move for you to sell on Shopify. The POS can stay.
Replace the POS
A third path is changing the register itself to Shopify POS and leaving Square. That can be right. It is a hardware, training, and payments project, not a sync project. SquareFloww will not switch the register for you. If you want one vendor on the floor and you have already chosen, finish that project. Do not install a sync app for a POS you plan to unplug next month.
When keeping Square POS and selling on Shopify is the right call
Keep both when the floor is fine and the website is the gap.
- Staff already know Square. Retraining the Saturday team is a real cost, and you do not have to pay it to get a better online store.
- In-person cards stay on Square. SquareFloww does not move that money flow. Readers stay readers.
- You want Shopify for the online catalog, the theme, and the apps around the storefront.
- You sell from one or more locations and need each store’s count tied to a Shopify location, not a single blended number.
- You are tired of typing products twice, not tired of Square itself.
If that list sounds like your shop, the next step is a connection, not a rip-and-replace. Start with How to connect Square to Shopify.
When a full switch can be the better call
Keeping both is not a virtue. Switch, or at least plan a switch, when one stack is what you actually want.
- Leadership wants a single vendor and will fund the retraining. Two admins forever is an ops tax. Pay it only if both systems earn their place.
- You have no in-person Square dependency. No hardware, no book of in-store regulars on Square, no reason to keep the POS lights on.
- The company has standardized on Shopify POS. A sync back to Square would fight that standard.
- Your pain is Square’s website, and you are happy to leave the POS conversation to a later quarter. Then migrate the website and decide about the register with clearer eyes.
Official help from Shopify and Square is the right source for a true migration or a POS change. We will not fake a feature-by-feature bake-off here. If you do switch POS, turn off any sync that still writes the old register, or you will update a system nobody uses.
How sync makes “keep both” workable
Two live catalogs drift. Sync is what makes the dual setup boring, which is what you want.
SquareFloww covers:
- Products: title, description, price, and image, linked by SKU or title
- Inventory: a Shopify location paired with a Square location
- Customers in either direction, with automatic customer updates on Growth and Pro
- A primary store: product and stock updates copy from the store you edit to the other one
| Plan | Price | Products | Customers | Location pairs | Sync |
|---|---|---|---|---|---|
| Starter | $19/mo | 1,000 | 500 | 1 | Manual |
| Growth | $39/mo | 2,000 | 2,000 | 3 | Automatic |
| Pro | $79/mo | 10,000 | 10,000 | Unlimited | Automatic |
One store and a person who can run sync: Starter is enough to prove you can keep Square and sell on Shopify. More than one location, or no one to press the button: Growth or Pro. The trial is seven days. The product page with the same numbers is Shopify Square integration.
Stock, because it is the usual reason dual systems hurt: Sync Square inventory with Shopify. Several doors: Multi-location inventory with Shopify and Square.
If you searched “switch” or “migrate”
“Switch from Square to Shopify” might mean you want Shopify’s website and you are willing to keep Square POS. Connect the systems and sync.
It might mean you want off Square entirely. Do not buy a sync subscription as a stepping stone you will resent. Finish the decision, then pick a tool.
“Migrate Square to Shopify” often means the website import. Do that import if you are leaving Square Online. Then, if the register stays, add ongoing sync so the import is not the last time the two catalogs agreed.
