Step 1: Convert Lightspeed Retail (X-Series) POS Loyalty into Marsello Points

When setting up your loyalty program, it’s important that your Marsello earning rules match your Lightspeed Retail (X-Series) POS Loyalty settings. This keeps your customers' balances worth the same after you switch.

Example 1: Default setting

If your Lightspeed Retail (X-Series) POS is set to:
$1 = $1 Loyalty
Then in Marsello, your Making a purchase earn rule should be set to:
“Earn 1 point for every $1 spent.”

📝 Note: This is Marsello’s default “Making a purchase” setting.

Example 2: Custom loyalty conversion

If your Lightspeed Retail (X-Series) POS is set to:
$5 = $1 Loyalty
Then in Marsello, your Making a purchase earn rule should be set to:
“Earn 1 point for every $5 spent.”

Example 3: Creating a new Marsello loyalty program

If you are creating a new loyalty program in Marsello, you may need to convert your customers’ existing Lightspeed Retail (X-Series) POS loyalty balances to align with your new Marsello earning rules.

Example Conversion

If your Lightspeed Retail (X-Series) POS is set to:
$10 = $1 Loyalty
And in Marsello, your earn rule is set to:
“Earn 1 point for every $1 spent.”
Then you must multiply your customers’ existing loyalty balances by 10.
This ensures their updated Marsello balances match the new points earning rule.

Step 2: Move your customers' existing loyalty balances into Marsello

Use Update existing customers to bring your customers' Lightspeed loyalty balances into Marsello. Your customers must already be in Marsello through your Lightspeed X-Series connection. The update only updates existing customers — it never creates new profiles. Rows that don't match exactly one customer will fail and be listed in your import report email.

In short, you'll:

Export your customers from Lightspeed and keep First Name, Last Name, your chosen identifier and Points Balance.
Convert balances if your Marsello earn rule differs from your Lightspeed setting (see Example 3 above).
In Marsello, go to Customers > All Customers, click the Manage Customer List dropdown and select Update existing customers.
Select Points, choose your identifier, choose to add to or replace current balances, then upload your file.
