Follow one Lightspeed sale

For shops that take money on a Lightspeed register and also sell online through Shopify. Lightspeed records a sale as fulfilled but does not store the carrier or tracking number, so Shopify carries the full dispatch record and Lightspeed carries the fact of it.

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

Listings do not publish to Shopify or Lightspeed on their own

Copying a listing from Shopify to Lightspeed (or the other way) always waits for you to look at it. Stock is the only thing that moves on its own, and only once you have turned it on.

The shipping gap

Lightspeed marks it shipped without keeping the number

Half a handshake, and worth knowing before you route posted orders through the till.

When you ship an order that came from Lightspeed, we tell Lightspeed the sale is fulfilled and it records exactly that. What it does not do is keep the carrier or the tracking number against the sale, because Lightspeed has nowhere to put them. So the sale stops looking outstanding, and the number that tells a customer where their parcel is does not live there.

The tracking number itself is not lost. It stays visible in QuickSync and on the Shopify order if that is where the sale started, which covers the common case of a customer emailing to ask. It only bites if your process is for someone to open Lightspeed and read the tracking off the sale, because that is the one place it will not be.

We would rather write this down than let you find it in week three. Lightspeed’s own integration is explicit about the limit, and a page that quietly said tracking syncs both ways would be wrong in a way you would only discover with a customer on the phone.

Before you connect

Lightspeed takes 64 characters of SKU

Shopify holds 255, so this is the length to design to.

Items pair up by SKU, and the shorter of the two limits is the one that governs. Shopify will store a SKU up to 255 characters; Lightspeed takes 64. Anything longer is truncated on the way across and then stops matching the item it came from, which shows up later as a count that will not move rather than as an error.

Sixty-four characters is generous enough that most catalogues never notice, so this is a five-minute check rather than a project. Sort by SKU length, look at the top of the list, and shorten anything that runs over before you turn sync on.

Speed

Neither side is on a timer

Both tell us the moment something happens, which is not true of every pair.

Shopify and Lightspeed both announce their changes to us, so a sale at the counter and a sale on the website each reach the other side without waiting for a scheduled check. Several channels we support cannot do this and have to be polled every couple of minutes; this pair is not one of them.

That matters on a busy Saturday rather than an ordinary Tuesday. If the same item sells in the shop and online inside the same minute, the second sale is not sitting behind a timer waiting to be noticed, which is the situation that produces an oversell.

Questions people ask about this pair

Does Shopify integrate with Lightspeed?

Yes, through QuickSync. Connect Shopify and Lightspeed, match products by SKU, and a sale on either side lowers the count on the other.

Does QuickSync send tracking numbers to Lightspeed?

We mark the sale fulfilled in Lightspeed, but Lightspeed does not store a carrier or tracking number against it, so the number itself stays in QuickSync and on the originating shop’s order. The sale stops showing as outstanding; the tracking detail just lives somewhere else.

How do I connect Shopify to Lightspeed?

You connect your shop from QuickSync and approve it in your Shopify admin. Shopify asks which permissions to grant and you can withdraw them from the Shopify side at any time. 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 64 characters, Lightspeed’s limit.

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

No. We match your existing Shopify and Lightspeed listings by SKU, and hand you a short list of whatever we could not match. You can also copy a listing from one side to the other if you want it in both places; that step always waits for you.

Can I charge a different price on Lightspeed?

Yes. Set a rule once for Lightspeed: a percentage, a fixed uplift, or a price you type yourself. We apply it whenever the price changes, and nothing forces Shopify and Lightspeed to the same number.

Does the tracking number go back to both shops?

On Lightspeed we mark the sale shipped, but Lightspeed does not keep the carrier or tracking number, so that detail stays visible in QuickSync. The other side gets the full number when it accepts one.

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

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

Which plan do I need for Shopify and Lightspeed?

Lite covers Shopify and Lightspeed. Lite is $19 a month for two shops and holds 1,000 items, with up to eight connected integrations. You would move up a plan for catalogue size, and your bill goes up by another $19 if you connect a third shop.
