How Retailers Can Use Meta Ads to Re-Engage Existing Customers and Increase In-Store Sales

If you’ve ever struggled to grow your retail business as quickly as you’d like, it might be because you’re overlooking your biggest opportunity for low-cost, profitable growth — your existing customers.

In this article, we’ll show you exactly how to target your current customers on Meta (Facebook and Instagram) using your own POS data to drive more repeat visits and sales.

Here’s a stat to get us started: 59% of your customers who have shopped with you only once have never returned.

Meaning? Most retailers don’t have a real strategy to drive customers back in-store — and that’s where we come in.

At Omni, we make this simple with our software Omni Lightning — a tool designed to connect your POS system directly with Meta so you can target past customers with precision.

Why Targeting Existing Customers on Meta Matters

Your current customers already know and trust you. They’ve bought from you before — and it’s far cheaper to get them to shop again than to acquire a brand-new buyer.

What many retailers don’t realize is that you can actually match your POS customer data (name, phone, and email) to their Facebook and Instagram profiles.

When that match happens, you now have a powerful new audience sitting inside Meta Ads Manager — ready for you to target with ads that drive them back in-store.

It really is that simple.

The 3 Steps to Turn POS Data Into Meta Ads That Bring Customers Back

1. Integrate Omni Lightning With Your POS System

No matter which POS system you use, Omni Lightning can connect directly through an API.

Our team of developers handles the integration so we can securely sync your customer data and automatically create a Custom Audience on Facebook for you.

From there, Meta recognizes those customer profiles — and they become a ready-to-target audience inside Ads Manager.

Pro Tip: You can also segment audiences by purchase frequency, category, or store location for even more personalized ads.

2. Run Paid Meta Ads to Those Customers

This audience targeting works through Meta’s paid advertising platform, not organic posts.

Once your audience is created, you can run campaigns that reintroduce your business to these customers and remind them to come back in.

Example:
Let’s say your POS system has 20,000 customers. On average, Omni Lightning matches about 75% of them to Facebook and Instagram profiles — giving you a 15,000-person audience for your ads.

Run ads that:

• Announce new products or seasonal updates

• Highlight sales or limited-time offers

• Invite customers to exclusive in-store events

Bonus Tip: You can even target customers who have moved outside your store radius with eCommerce ads to boost online sales.

3. Track Every Visit and Sale to Measure ROI

Here’s the best part — you can track which of these customers saw an ad and then came back in-store.

If you’ve ever felt frustrated by not knowing the ROI of your Facebook or Instagram ads, this is your solution.

That’s actually why we built Omni Lightning. Retailers used to ask us, “How many people came into my store from our ads?” — and for years, there wasn’t a great answer.

Now there is.

Omni Lightning tracks all Meta activity. When someone who saw one of your ads comes back in-store and makes a purchase, we recognize that match.

If they shop within 28 days of seeing an ad, it’s counted directly in your dashboard. You’ll see how many repeat transactions and how much revenue your ads generated — all in real time.

The takeaway: You’ll know exactly which ads drove foot traffic and repeat sales — no more guessing.

The Economics: Why This Approach Pays Off

Let’s break down the math for a typical retailer.

If your average order value is $150 and you can bring even 5% of your 15,000 matched customers back in-store, that’s:

15,000 × 5% = 750 transactions
750 × $150 = $112,500 in sales

That’s the power of targeting customers who already know you — at a fraction of the cost of finding new ones.

Ready to Grow by Focusing on the Customers You Already Have?

Before you launch your next Meta ad campaign, think about this: Are you including your existing customers in your targeting?

Using Omni Lightning, you can:

• Re-engage past customers on Facebook and Instagram

• Track who comes back in-store after seeing an ad

• Increase lifetime value with repeat business

Stop chasing new customers before you’ve re-engaged the ones you already earned.
