Integration

Q. Can I connect multiple Lightspeed Restaurant K-Series accounts to one Marsello account?

A. Yes. You can connect multiple Lightspeed Restaurant K-Series accounts to one Marsello account where that setup is supported for K-Series. However, this does not override Marsello’s account-wide rule that each Marsello account is limited to one eCommerce integration. If you need to connect multiple eCommerce sites, you’ll need a separate Marsello account for each site. Only use this Lightspeed Restaurant K-Series setup when it fits within that one eCommerce integration limit.

Q. Is there a historical sync for customers and orders through the integration?

A. No, the Lightspeed Restaurant K-Series API doesn't currently support historical sync. We suggest exporting your Lightspeed K-Series customer database and then following these steps to import customers into your Marsello account.

Q. How long does it typically take for data, such as an order, to sync from Lightspeed Restaurant K-Series to Marsello?

A. Once the connection is established, all completed orders from Lightspeed K-Series will automatically sync through a scheduled polling process that runs approximately every 5 minutes. Depending on the processing volume, additional queue time may apply. In most cases, orders and customer data appear in Marsello within 5-10 minutes, although occasional delays may occur during periods of high activity.

Q. Does Marsello integrate with the Lightspeed Restaurant K-Series built-in order ahead features?

A. No. Marsello isn't currently integrated with the Lightspeed Restaurant K-Series built-in order ahead features. If this is something you'd like to see added, feel free to vote for this feature. Your feedback goes directly to our product team and helps us prioritize what's most important to you!

Q. If my eCommerce orders sync into my POS account, will this award double points for the same order?

A. No. Customers won't earn double points for the same order, because Marsello has checks to prevent this. For example, if an order is placed through your eCommerce platform (this applies only to Shopify, WooCommerce, BigCommerce and Ecwid platforms connected to Marsello), the customer earns points for that online purchase. If the same order later syncs to your POS account, the customer won't earn additional points, and vice versa. This means customers earn points only once per order, which keeps your loyalty program fair.

Q. If a customer signs up to Marsello via the Customer Portal, will that customer sync to the POS automatically (and how long does that take), or do staff still need to add them manually?

A. No. A customer who signs up through the Marsello Customer Portal doesn't sync to your Lightspeed Restaurant K-Series POS automatically. Staff need to add the customer to the POS manually for their first order. Once that order is placed, the customer's details sync to Marsello and link to their Customer Portal profile.

Currently, Marsello can only access order data from K-Series, so customer information is received only when an order is completed.

Q. Is there a loyalty program link (URL) that I can share with my customers?

A. Yes. You can share your in-store portal link with customers. The in-store portal link automatically opens the loyalty widget, so customers can access and interact with your loyalty program.

Q. Can you exclude customers from the loyalty program automatically with Lightspeed K-Series?

A. Yes. If a customer removes a reward or email discount from their sale, they will still have access to the discount code for future use. The code can be viewed in their loyalty profile. Removing the discount does not refund the loyalty points used to redeem it.

Q. Do customers sync between Lightspeed X-Series and K-Series in Marsello?

A. No, customers do not sync between X-Series and K-Series. Marsello also doesn’t create customers in K-Series, so they’ll need to import their customer list manually into K-Series.

During a sale: staff should add products, then add the customer, and click the loyalty button to access their loyalty profile. Marsello matches the customer by email address to their Marsello account.

Q. Does Lightspeed K-Series support QR code scanning for loyalty programs?

A. No, Lightspeed K-Series doesn’t support QR code scanning for loyalty right now.
