Oliver POS doesn't have a partnership with Omnisend. It supports Omnisend because Omnisend ships an official WooCommerce plugin that already syncs subscribers, customers, and orders from WooCommerce into Omnisend. Oliver writes every in-store sale into WooCommerce as a normal order, the Omnisend plugin treats it the same way it treats an online order, and every email + SMS workflow keys off the unified data. Omnisend does the messaging. WooCommerce is the system of record. Oliver is the till on top.
What Omnisend is, exactly
Omnisend is the e-commerce email + SMS platform built for small and mid-market online retailers. It ships with pre-built workflow templates for welcome series, abandoned cart, browse abandonment, post-purchase, and review request — all tuned for the typical online-store lifecycle. The platform is positioned as the fast-to-launch alternative to Klaviyo, with simpler segmentation and easier onboarding for teams that don't want to spend a quarter configuring a marketing-automation tool.
The Omnisend Email Marketing & SMS for WooCommerce plugin syncs subscribers, customers, products, and orders into Omnisend in real time. Profiles include first/last name, address, total spent, and a list of purchased products. Omnisend's workflow templates can be turned on with the WooCommerce sync as the data source — no custom event mapping required.
How Oliver POS feeds in-store sales into Omnisend
The Omnisend WooCommerce POS flow inside Oliver is short:
- The cashier rings the sale on the Oliver register and taps Charge.
- Oliver prompts to attach a customer — by email lookup, phone-number lookup, or a fresh customer card with marketing + SMS consent.
- The cashier takes payment through whatever WooCommerce payment gateway the store uses.
- Oliver writes a standard WooCommerce order with the customer ID, line items, totals, and payment method.
- The Omnisend plugin's background sync sees the order through WooCommerce hooks, posts it to Omnisend, and updates the contact's profile.
- Pre-built workflows that listen for Order Placed or Order Paid fire immediately. SMS workflows fire too, provided the shopper has opted in at the counter.
End to end, the in-store sale reaches Omnisend within seconds of the cashier closing the order. The customer is in the same audience as your online buyers, with the same total-spend and last-purchase fields populated, ready for the next campaign send.
The Omnisend WooCommerce plugin — what Oliver rides on
Oliver rides on the official Omnisend Email Marketing & SMS for WooCommerce plugin, maintained by Omnisend. The plugin is the standard path for any WooCommerce-plus-Omnisend store and handles the customer sync, the order sync, and the on-site tracking script for the WooCommerce online checkout.
Setup mirrors any other Omnisend onboarding: install the plugin, connect to your Omnisend account, pick your audience, and let the initial sync run. Once that's done, every WooCommerce order — including every Oliver POS register sale — flows into Omnisend on the same path.
Why pushing in-store sales into Omnisend matters
Omnisend's pre-built workflows are tuned for online stores — and that's the cohort it serves best. A retailer adding Oliver POS to a WooCommerce store will, however, quickly notice the gap:
- Post-purchase automations send review requests for products the customer bought online but never for products they bought at the counter.
- Win-back workflows treat in-store regulars as lapsed customers.
- Product-recommendation blocks reflect only online purchase history.
- Cross-channel campaigns (email and SMS to the same audience) miss the half of the customer base that only shops in person.
Closing that gap is the difference between Omnisend feeling smart and feeling oblivious. Push Oliver POS sales through the WooCommerce sync and the same workflows widen to include the whole business. Reporting reflects real lifetime value, not just online lifetime value.
What this is NOT
Oliver POS is not an Omnisend partner. There's no co-marketing agreement, no revenue share, and no special pricing. Oliver doesn't insert itself between WooCommerce and Omnisend; the data path is the same one any WooCommerce store uses. Oliver doesn't charge a markup, doesn't add per-contact fees, and doesn't take a cut of any Omnisend send. Your Omnisend account and contract are entirely between you and Omnisend.
Setup in 4 steps
- Install the Omnisend for WooCommerce plugin and connect it to your Omnisend account.
- Verify the initial customer + order sync completes and confirm a recent online order appears against the matching Omnisend profile.
- Install Oliver POS, sign in to the register, and confirm the customer-capture prompt with marketing + SMS consent is enabled at checkout.
- Run a small live test sale at the counter, attach a customer, and confirm the order appears in Omnisend within a few seconds.
FAQ
Will Omnisend SMS workflows include in-store customers?
Yes — provided the shopper has explicitly opted in to SMS at the counter. Oliver captures the phone number with a consent prompt; the number flows into WooCommerce, the Omnisend plugin syncs it, and the SMS workflow can target the contact.
Do Omnisend's product-recommendation blocks include products bought in store?
Yes. Omnisend's recommendations are based on the contact's purchase history in Omnisend, which now includes counter purchases via the WooCommerce sync. The blocks reflect everything the customer has bought, online or in store.
Does Oliver POS partner with Omnisend?
No. Oliver POS is not an Omnisend partner. Omnisend is supported because it ships an official WooCommerce plugin that any WooCommerce store can install, and Oliver writes register sales into WooCommerce as standard orders the plugin syncs.
Does Oliver charge extra to use Omnisend?
No. Oliver's pricing is a flat monthly POS software fee. You pay Omnisend directly on Omnisend's published pricing.
Will my online + in-store customers be one profile in Omnisend?
Yes. Omnisend matches by email; Oliver POS attaches the WooCommerce customer to every register sale, so the shopper has one Omnisend profile spanning online and in-store activity.
