Marsello WooCommerce POS — Oliver POS Integration Guide

Oliver POS doesn't have a partnership with Marsello. It supports Marsello the same way any WooCommerce store does — through the WooCommerce connector (Marsello for WooCommerce), which already handles points, balances, rewards, tiers, and redemption for your online store. Once you understand that, the rest is mechanical: the Oliver POS register opens Marsello in an in-POS browser view with the WooCommerce customer already attached, the plugin recognises the shopper, the cashier sees balances and applies redemptions in the same flow as a normal sale, and the closing sale writes back through WooCommerce to award fresh points. WooCommerce is the system of record. Marsello is the loyalty engine. Oliver is the till on top.

What Marsello is, exactly

One of the few loyalty platforms designed from the ground up for omnichannel retail — built originally for retailers running both an online store and a brick-and-mortar POS.

For our purposes the important thing about Marsello isn't any specific feature — it's that the WooCommerce connector is mature, well-supported, and works at the WooCommerce-customer-and-order level. Oliver POS doesn't add a second Marsello integration or duplicate the loyalty database. It opens Marsello in an in-POS browser view at the till and lets the existing plugin do its job, with the WooCommerce customer attached.

How Oliver POS opens Marsello at the register

The Marsello WooCommerce POS flow inside Oliver is short and predictable:

1. The cashier rings the sale on the Oliver register, scans or selects items.
2. Oliver prompts to attach a customer — by email lookup, phone-number lookup, or a fresh customer card.
3. Oliver opens the WooCommerce checkout (or Marsello's customer view, where the plugin exposes one) in its in-POS browser view, with the attached WooCommerce customer ID already in session.
4. Marsello's plugin recognises the customer and surfaces their points balance, current tier, available rewards, store credit, or wallet.
5. The cashier applies a redemption (or accepts an auto-applied tier benefit) in the same UI the customer would use online.
6. The cashier takes payment through whatever WooCommerce payment gateway the store uses.
7. Oliver writes a standard WooCommerce order with the customer ID, line items, totals, and any redemption / discount applied.
8. Marsello's the WooCommerce connector runs its standard earn rules on the closing order — points credited, tier advanced, referrer credited, achievement unlocked — and the customer's balance updates within seconds.

End to end, the in-store sale earns and burns Marsello the same way an online sale does. There's no parallel POS-only loyalty database to reconcile.

The Marsello WooCommerce plugin — what Oliver rides on

Oliver doesn't add a second Marsello integration or duplicate the data path. The plugin Oliver rides on is the standard Marsello for WooCommerce, available at www.marsello.com/integrations/woocommerce. It's built specifically to handle the WooCommerce ↔ Marsello data path, including customer matching, redemption application, and the standard reporting flow.

Setup is identical to setup for any WooCommerce store: install the plugin, connect it to your Marsello account, configure earn rules / redemption thresholds in the dashboard, and you're live. Once that's done, every WooCommerce order — including every Oliver POS register sale — runs through the same Marsello pipeline.

Earn-and-burn at the counter — the in-POS browser story

The single biggest unlock for in-store loyalty is the in-POS browser view. Oliver POS doesn't reimplement Marsello's UI at the till. It opens the same WooCommerce checkout page (or Marsello's customer-facing view) that the customer would see online, inside a browser pane embedded in the cashier's register screen. The WooCommerce customer is already attached, so Marsello recognises the shopper, shows the same balance the customer sees on their account page, and offers the same redemption widget the website uses.

The cashier never has to context-switch. The redemption applies as a normal cart-level discount. The tendering flow continues as a normal Oliver sale. The closing order writes to WooCommerce, Marsello sees it the same way it sees an online order, and the customer's balance updates before the receipt prints. Loyalty programs that fall apart in store because the cashier can't see the balance — the most common failure mode for SaaS loyalty platforms with thin POS support — don't fall apart here, because the cashier is looking at the same loyalty UI the customer is.

Why in-store loyalty matters when half your revenue is in store

Most retailers running Marsello on a WooCommerce store have an online-skewed loyalty program, because online is where the platform was always integrated. The result is a loyalty program that knows everything about online purchases and almost nothing about counter sales. The downstream consequences are real:

• Customers who shop in store can't earn. A regular customer who buys at the counter never sees their points balance grow, never advances tiers, and eventually stops believing the program covers them.
• Tier benefits are wrong. A customer who has hit Gold tier through online + in-store activity combined gets treated as Bronze at the counter, because the in-store sales never made it into Marsello.
• Referral attribution leaks. A referred customer who first buys in store doesn't credit the referrer, because the referral relationship never gets a qualifying-purchase event.
• Lifetime-value reporting is half-blind. Marsello's analytics treat the customer as low-value because half their spending is invisible. Segmentation, churn alerts, and campaign targeting all skew wrong.

Open Marsello at the counter through Oliver POS and all of those problems resolve at once. The customer earns and burns the same way online and in store. Tiers reflect total spend. Referral attribution closes the loop. Analytics see one customer with one full purchase history. The loyalty program finally does what you're paying for it to do.

What this is NOT

Oliver POS is not a Marsello partner. There is no co-marketing agreement, no revenue share, and no special Marsello pricing for Oliver merchants. Oliver does not insert itself between WooCommerce and Marsello; the data path is exactly the same one any WooCommerce store uses. Oliver doesn't charge a markup, doesn't add a per-redemption fee on top, and doesn't take a cut of the Marsello subscription. Your Marsello account, dashboard, and contract are entirely between you and Marsello.

It's also worth saying that Oliver POS doesn't change the data ownership story. The WooCommerce orders and customer table on your own WordPress install remain the source of truth. Oliver writes into it; Marsello reads from it through the WooCommerce connector. If you ever leave Marsello, the data stays where it has always been — in WooCommerce.

Setup in 4 steps

1. Install Marsello for WooCommerce on your WordPress site and connect it to your Marsello account, mapping earn rules, redemption thresholds, and any tier definitions.
2. Verify the plugin works end-to-end online — place a test order on the website and confirm points / rewards / redemptions behave as expected.
3. Install Oliver POS, sign in to the register on your counter tablet, and confirm the customer-capture prompt is enabled at checkout.
4. Run a small live test sale at the counter, attach a known customer, confirm the cashier sees their Marsello balance in the in-POS browser view, apply a redemption, and confirm the closing sale awards new points / credit.

FAQ

Does Oliver POS replace Marsello or just surface it at the register?

It surfaces it. Oliver POS doesn't run a parallel loyalty database. Marsello remains the source of truth for balances, tiers, rewards, and referral attribution; Oliver opens Marsello's UI in an in-POS browser view at the counter with the customer attached so the same balance and rules work in-store.

Does Oliver POS have a partnership with Marsello?

No. Oliver doesn't partner with Marsello or any other loyalty platform. We support Marsello because the WooCommerce connector already handles the loyalty flow for your online store — and Oliver writes every in-store sale into WooCommerce as a standard order, so the same plugin picks it up automatically. Your Marsello account stays between you and Marsello.

Does Oliver charge extra to use Marsello?

No. You pay Marsello directly on Marsello's published subscription pricing. Oliver's pricing is a flat monthly POS software fee that has nothing to do with the loyalty platform you choose.

Will the cashier see the customer's Marsello balance at the Oliver POS register?

Yes. Oliver POS attaches the WooCommerce customer to the in-POS browser session, so when Marsello's plugin loads in the browser view it already knows who the shopper is and surfaces the same balance, tier, and available rewards the customer sees on the website's account page.

Will my in-store and online activity build one unified loyalty profile?

Yes. Oliver POS writes register sales into the same WooCommerce store that powers your online checkout, so by the time orders reach Marsello they're a unified order stream against one customer record. Marsello sees one earn history, one redemption history, one tier progression — no manual reconciliation between an online and an in-store program.
