Example: follow one Lightspeed sale

For businesses with a Squarespace site out front and a Lightspeed register in the shop. Squarespace announces orders straight away but not stock you edit yourself, and its 60-character SKU is the tighter of the two.

What to know before you connect

Inventory limit

Lightspeed marks it shipped, without the number

Lightspeed records a sale as fulfilled but does not keep a carrier or tracking number against it. We mark it shipped and the number stays visible in QuickSync.

Manual control

Review export and draft settings for Squarespace and Lightspeed

Connecting Squarespace and Lightspeed imports their catalogues. A confirmed Sync Products export can create missing products. Ongoing product syncing follows your master store on Pro or higher. Use Create as drafts where supported when you want to review copies before publication.

Speed

Orders arrive at once; your own edits wait

The two paths through Squarespace run at different speeds.

A sale on either side reaches the other in about a second: Squarespace announces its orders immediately and so does the register. The slower path is stock you edit by hand inside Squarespace, which it tells no one about; we pick that up on our next look, a couple of minutes later.

In practice that means recounts belong in one place. Adjust the number in QuickSync or at the register and both sides carry it; adjust it inside Squarespace and it arrives on the next check.

The details

Sixty characters, and a sale marked shipped

Squarespace connects with a key, and Lightspeed keeps no tracking number.

Squarespace connects differently from the register: you generate an API key in Squarespace and paste it into QuickSync, and nothing on the site changes until you switch sync on. The shared SKU has to fit Squarespace’s 60 characters, the tighter side of this pair.

Tracking goes to the Squarespace order as normal. Lightspeed marks its own sales fulfilled without keeping the number, so shipping detail for register sales stays in QuickSync.

Questions people ask about this pair

How do I connect Squarespace to Lightspeed?

You generate an API key in Squarespace and paste it into QuickSync. You sign in to Lightspeed X-Series and approve QuickSync for the outlet you want connected. Then match products by SKU, choose which shop holds the true count on day one and turn the sync on. Keep SKUs within 60 characters, Squarespace’s limit.

Does Squarespace integrate with Lightspeed?

Not directly: neither offers a built-in link. QuickSync sits between them, matching items by SKU (60 characters or fewer, Squarespace’s limit) and keeping both sides in step automatically.

How does the Squarespace connection work?

You generate an API key in Squarespace and paste it into QuickSync; the register connects by signing in to Lightspeed X-Series. Nothing is written to either side until you turn sync on, so you can review what matched first.

Do I have to re-list my Squarespace products on Lightspeed?

No. Existing Squarespace and Lightspeed listings match by SKU. A separate Sync Products export can create missing products. Ongoing product updates require Pro or higher and a master store. Review the export scope and draft setting before confirming a write.

Can I charge a different price on Lightspeed?

Yes, on Ultra or higher. Set a price-modification rule for Lightspeed in its store settings. Ongoing price updates follow the product master and the selected rule, so Squarespace and Lightspeed can use different prices.

Does the tracking number go back to both shops?

Supported shipment updates return to the original order when the connected fulfillment store supplies them. Supported tracking details can return to the originating Squarespace order. QuickSync can mark the Lightspeed sale shipped, but does not store the carrier or tracking number there.

Does a Squarespace order get recreated on Lightspeed?

Eligible Squarespace orders can create a routed copy in Lightspeed when you choose it as your fulfillment store and enable order syncing on Pro or higher. The original stays in its source store. Unsupported directions, order state and your settings can prevent a copy in Lightspeed.

What happens if a buyer cancels or I refund them on Squarespace or Lightspeed?

A refund alone does not restock an item. When the originating platform reports a stock increase, QuickSync propagates the updated quantity between Squarespace and Lightspeed.

Which plan do I need for Squarespace and Lightspeed?

For Squarespace and Lightspeed, Lite starts at $19/month for two stores and 1,000 syncing items and includes inventory syncing. Ongoing product updates and order syncing require Pro or higher; price modification requires Ultra or higher. Choose a plan for both your features and catalogue size. Extra stores are billed at the selected plan rate; see Pricing for current limits.
