Many new merchants running Facebook Ads often face the same frustrating problem: your ads get clicks, traffic seems fine, but ROAS stays low, costs keep rising, and your pixel barely learns anything.

You may already have the Pixel installed, maybe even CAPI enabled, yet performance still feels inconsistent. And the reason is simpler than most people realize:

“Your pixel is not seeing all the conversions that actually happen.”

In real-world ecommerce, a large portion of orders don’t happen directly on the website. Instead, they come from:

• COD confirmations
• Messenger or WhatsApp chats
• Phone call orders
• In-store purchases
• Leads who pay later

All of these conversions are invisible to your Pixel, which means Facebook is missing the data it needs to optimize your ads properly. This is where Offline Events come in — a solution designed to close the gap between what happens online and what really happens in your business.

In this guide, you’ll learn:

• What Offline Events are
• Why they matter for Pixel learning
• How they help reduce costs and improve ROAS
• And most importantly: “How to enable Offline Events inside the Orichi Pixel App in just a few steps”

What Are Offline Events?

When you run Facebook ads, your Pixel tracks how people behave on your website — things like viewing a product, adding to cart, initiating checkout, or completing a purchase.

But in many businesses (especially in markets like Vietnam or Southeast Asia), a large share of real conversions happen outside the website. These are actions your Pixel simply cannot see, such as:

• COD orders confirmed by your staff
• Purchases made through Messenger or WhatsApp
• Orders placed via phone call
• Customers buying at your physical store
• Leads that convert later, not during the online session

These “offline” conversions still matter. They still generate revenue. They still count as results influenced by your ads — Facebook just doesn’t know they happened.

This is exactly what Offline Events are designed to solve. With Offline Events, Facebook allows you to send these real-world conversions back to the system so it can:

• Understand how ads influence offline purchases
• Attribute conversions more accurately
• Improve the quality of your data
• Train the pixel with the full picture, not just website activity

In other words:

” Offline Events let Facebook see the conversions your Pixel misses — so your ads can optimize based on all your actual sales, not just the online ones.”

Offline Events essentially complete the tracking process and give you a more realistic view of your marketing performance.

Why Are Offline Events Important for the Facebook Pixel?

To understand why Offline Events matter, it helps to know how the Facebook Pixel actually learns. The Pixel improves its performance by observing conversions — the more complete the data, the smarter the optimization. But there’s a catch:

“The Pixel can only learn from what it can see on your website.”

That’s a problem for many merchants whose sales don’t happen entirely online. COD orders, chat-based sales, phone bookings, and in-store purchases all take place outside the Pixel’s reach. As a result, Facebook receives only a fraction of your real customer activity.

And when the Pixel learns from incomplete information, you’ll likely notice:

• Higher cost per purchase
• Inconsistent ROAS
• Slow learning phase
• Poor audience targeting
• Limited ability to scale

This is where Offline Events make a dramatic difference.

By sending offline purchases back to Facebook, you help the system:

• Recover missing conversion data
• Train the pixel with more accurate signals
• Understand which ads truly drive sales
• Improve attribution across campaigns
• Reduce optimization waste
• Find more people who behave like your real buyers

Offline Events are especially helpful for new pixels, which typically need 50–100 conversions before stabilizing. If most of your early sales are COD or chat-based, the Pixel won’t reach that threshold unless you upload offline data.

Once Offline Events are enabled, Facebook finally receives the complete picture of your customers’ actions:

“More conversions → better learning → lower cost → stronger ROAS.”

It’s one of the simplest yet most impactful upgrades you can make to your tracking setup.

How Facebook Uses Offline Events

Once your offline data is uploaded, Facebook begins matching those real-world actions with people who interacted with your ads. This is where the system becomes surprisingly powerful — it doesn’t just store your data; it actively uses it to improve your campaigns.

Here’s how the process works.

Facebook compares your offline conversions against multiple signals, such as:

• Phone number
• Email address
• Customer name
• Location details
• Order time
• Order value

Using these identifiers, Facebook attempts to match each offline purchase with a user in its system who may have:

• Viewed your ad
• Clicked your ad
• Engaged with your page
• Landed on your website but bought later
• Interacted with your brand across platforms

Once a match is found, Facebook attributes the conversion to the appropriate:

• Campaign
• Ad set
• Ad

This gives you a more accurate view of how your ads contribute to sales — even if those sales happen outside your website. But the real benefit goes deeper than reporting.

With matched Offline Events, Facebook can:

• Strengthen the pixel’s learning signals
• Improve the accuracy of Optimization Events
• Enhance your Lookalike Audiences
• Refine targeting in Conversion and Advantage+ campaigns
• Boost retargeting effectiveness
• Reduce wasted spend by identifying true buying patterns

Instead of optimizing based on partial information, Facebook can now optimize based on a complete customer journey, both online and offline.

“Better data means better decisions — not just for you, but for the algorithm too.”

When Should You Use Offline Events?

Not every business relies entirely on online checkouts — and for many new merchants, that’s exactly why their tracking feels incomplete.

If a significant portion of your sales happens outside the website, your Pixel simply doesn’t receive enough data to optimize properly. Offline Events are especially useful in situations where online tracking alone can’t tell the full story.

You should strongly consider enabling Offline Events if your business:

• Handles COD(Vietnam, Indonesia, Thailand, India, and others…) (Cash on Delivery) orders
• Takes orders through Messenger, WhatsApp, or phone calls
• Confirms purchases manually through a support team
• Has a physical store and sells offline
• Generates leads first and closes sales later
• Uses POS or CRM systems to complete transactions
• Runs Conversion or Advantage+ Shopping campaigns
• Is working with a new pixel that needs more learning data

For many merchants — especially in markets where COD and chat-to-order are common — Offline Events are not just helpful; they are almost essential. Without them, Facebook only sees a small percentage of your actual sales, which leads to:

• Slow learning phases
• Unstable ROAS
• Higher cost per purchase
• Weaker audience optimization

Once Offline Events are enabled, Facebook finally gets visibility into all your real conversions, not just the online ones.

“If your sales happen anywhere outside the website, Offline Events should be turned on — no exceptions.”How Offline Events Work Inside the Orichi Pixel App

For many merchants, the biggest challenge with Offline Events is the technical setup. Manually exporting CSV files, cleaning customer data, and uploading them to Facebook can be confusing — especially if you’re new to tracking.

That’s exactly why the Orichi Pixel App automates the entire process for you. Instead of dealing with spreadsheets or manual uploads, the app handles everything in the background and sends your offline conversions to Facebook in real time.

Here’s how Orichi makes Offline Events easy for beginners:

Automatic Order Sync from Shopify

The app collects your orders directly from Shopify, including:

• COD orders
• Paid online orders
• Messenger or phone-confirmed orders
• POS orders
• Draft and manual orders

No matter how the sale happens, Orichi captures it.

Data Cleaning and Normalization

Before Facebook can use your offline data, it must be correctly formatted and processed.

Orichi automatically:

• Hashes customer information using SHA256 (Meta’s required standard)
• Normalizes phone numbers (e.g., converts 0 → +84 for Vietnam)
• Fixes common email formatting issues
• Removes duplicate entries
• Maps each order to the correct Purchase event

This step ensures Facebook can match your data accurately.

Sends Data to Meta Using Offline CAPI

Once cleaned, your offline orders are sent to Facebook using Offline CAPI, which is Meta’s recommended server-to-server method.

This improves:

• Match rate
• Tracking stability
• Pixel learning quality
• Overall reporting accuracy

The system also adds event_id to prevent duplicate conversions.

Real-Time Reporting Inside the App

You can see everything directly within Orichi:

• How many offline events were sent
• How many were matched by Facebook
• Match rate percentage
• Additional revenue attributed to offline data
• Individual logs for each order

This gives new merchants clarity and confidence that their tracking is working properly.

“once you turn it on, Offline Events continue running automatically — no maintenance and no manual uploads.”

• Assign the correct ad account and permissions

Once connected, you’re ready to send offline data.

Step 4 — Turn On “Upload Shopify Orders Automatically”

This is the core setting that activates Offline Events.

When enabled, Orichi will automatically upload eligible orders to Facebook.

You can choose:

• Upload all orders
• Upload only COD-confirmed orders
• Upload only completed Purchases
• Exclude canceled or fraud orders

This gives you control while still keeping things simple.

Step 5 — Check Status and Logs to Confirm Everything Is Working

After enabling, open the Logs tab to review:

• Events sent to Facebook
• Matched events
• Match rate
• Any warnings or unmatched data
• Shortcut link to view events in Meta Events Manager

Most data will appear in Facebook within a few minutes.

“From this point on, everything is automated.” Your offline conversions will continue syncing without any manual uploads.

Frequently Asked Questions (FAQ)

As new merchants begin working with Offline Events, a few common questions usually come up.

Here are the most important ones, explained clearly and simply.

Conclusion

Tracking is one of the most important parts of any Facebook advertising strategy — and for many new merchants, it’s also the easiest place to overlook real results. When your Pixel only sees online conversions, but most of your sales come from COD, chat, or offline interactions, Facebook ends up optimizing with only half the story.

That leads to higher costs, weaker targeting, and unstable ROAS. Offline Events fix that. They give Facebook the missing information it needs to understand your customers and optimize your campaigns accurately. With more complete data, the algorithm can:

• Learn faster
• Reduce cost per purchase
• Improve ROAS
• Strengthen retargeting
• Build better Lookalikes
• Deliver more consistent performance

And with the Orichi Pixel App, enabling Offline Events is no longer a complicated, technical task.

The app handles the syncing, data cleaning, matching, and reporting for you — automatically.
