Brevo WooCommerce POS — Oliver POS Integration Guide

Oliver POS doesn't have a partnership with Brevo. It supports Brevo (formerly Sendinblue) because Brevo ships an official WooCommerce plugin that already syncs contacts and orders from WooCommerce into Brevo. Oliver writes every in-store sale into WooCommerce as a normal order, the plugin treats it the same way it treats an online order, and every email, SMS, and CRM rule keys off the unified data. Brevo does the messaging. WooCommerce is the system of record. Oliver is the till on top.

What Brevo is, exactly

Brevo, the platform formerly known as Sendinblue, is a European email + SMS + CRM suite particularly popular with small and mid-market businesses across the EU. Brevo bundles email marketing, transactional email, SMS, chat, marketing automation, and a light CRM into a single platform — at pricing materially lower than HubSpot or Klaviyo, with EU data residency that simplifies GDPR compliance.

The Brevo for WooCommerce plugin (still listed under its previous Sendinblue name on WordPress.org) syncs new subscribers, existing customers, and orders into Brevo. Order data populates contact attributes — last order date, total spent, last product purchased — and Brevo's automation builder can target contacts based on those attributes.

How Oliver POS feeds in-store sales into Brevo

The Brevo WooCommerce POS flow inside Oliver is straightforward:

1. The cashier rings the sale on the Oliver register and taps Charge.
2. Oliver prompts to attach a customer — by email lookup, phone-number lookup, or a fresh customer card with marketing + SMS consent.
3. The cashier takes payment through whatever WooCommerce payment gateway the store uses.
4. Oliver writes a standard WooCommerce order with the customer ID, line items, totals, and payment method.
5. The Brevo plugin syncs the order to Brevo via API; the contact's attributes update; any automation listening for "Order placed" or for attribute changes fires.
6. SMS campaigns reach the contact too if they've opted in at the counter — Brevo handles SMS in the same workflow editor as email, with no separate SMS provider needed.

The Brevo WooCommerce plugin — what Oliver rides on

Oliver rides on the official Brevo for WooCommerce plugin, maintained by Brevo. Setup mirrors any other Brevo onboarding: install the plugin, paste your Brevo API key, pick the list to receive new contacts, and let the initial sync run. Once that's done, every WooCommerce order — including every Oliver POS register sale — flows into Brevo on the same path.

Why pushing in-store sales into Brevo matters

Brevo's heavy use among EU small businesses means a lot of retailers running it are exactly the kind of business that takes substantial counter revenue — bakeries, wine shops, boutique apparel, specialty food. The platform's strength is that one tool handles email, SMS, and a light CRM in a single place; the weakness is that without in-store data, the platform is only as informed as the WooCommerce online checkout makes it.

• Abandoned-cart automations exclude shoppers who bought in store.
• Birthday campaigns include the regulars whose only contact channel is the counter.
• RFM (recency, frequency, monetary) segmentation works the way it's supposed to.
• Brevo's transactional API, if you use it for WooCommerce receipts, sends in-store receipts the same way it sends online receipts.

What this is NOT

Oliver POS is not a Brevo partner. There's no co-marketing agreement, no revenue share, and no special pricing. Oliver doesn't insert itself between WooCommerce and Brevo; the data path is the same one any WooCommerce store uses. Oliver doesn't charge a markup, doesn't add per-email fees, and doesn't take a cut. Your Brevo account and contract are entirely between you and Brevo.

Setup in 4 steps

1. Install the Brevo for WooCommerce plugin and connect it to your Brevo account using your API key.
2. Pick the contact list to receive WooCommerce customers and verify the initial sync completes.
3. Install Oliver POS, sign in to the register, and confirm the customer-capture prompt with marketing + SMS consent is enabled at checkout.
4. Run a small live test sale at the counter, attach a contact, and confirm the order and attribute updates appear in Brevo within a few seconds.

FAQ

Is Brevo a good fit for EU GDPR compliance?

Brevo is headquartered in France and stores customer data in the EU, which simplifies the GDPR story for EU retailers. The Oliver POS + WooCommerce + Brevo flow keeps all customer data inside the WooCommerce database (your own host) and Brevo's EU infrastructure — there's no extra processor in the middle.

Will Brevo's transactional email replace the WooCommerce receipt email?

It can, but doesn't have to. Brevo offers a transactional email API that the WooCommerce store can use for order confirmations and shipping notifications. That works exactly the same for in-store sales as for online sales — when WooCommerce sends the order confirmation, Brevo handles delivery.

Does Oliver POS partner with Brevo?

No. Oliver POS is not a Brevo partner. Brevo is supported because it ships an official WooCommerce plugin that any WooCommerce store can install.

Does Oliver charge extra to use Brevo?

No. Oliver's pricing is a flat monthly POS software fee. You pay Brevo directly on Brevo's published pricing.

Will my online + in-store customers be one Brevo contact?

Yes. Brevo matches by email; Oliver POS attaches the WooCommerce customer to every register sale, so the shopper has one Brevo contact spanning online and in-store activity.
