We'll reach out the moment we're ready for you.

No spam. One email when we launch.

From your store to every ad platform - server-side.

SyncBeacon sits in the middle: enriching, deduplicating, consent-filtering and forwarding every conversion - automatically.

The market sells these as three separate tools.
We bundle them.

Server-side conversion tracking, automatic ad pausing, and a GTM replacement are sold by different vendors at different prices - or paid for in developer hours. SyncBeacon is the only platform that does all three, across every major e-commerce stack.

01

Server-side conversion tracking

Every purchase, add-to-cart and checkout captured server-side and dispatched to Meta, Google, Microsoft Ads, X Ads, Snapchat and Pinterest - immune to ad blockers, ITP and PayPal/Stripe redirect gaps.

Standalone server-side tracking tools charge $100–$249/mo for this alone.

02

Automatic ad pause on stock-out

When inventory hits zero, ads pause across all five platforms in seconds. When you restock, they resume automatically. No more burning budget on products you can't ship.

Dedicated ad-pause apps charge $49–$499/mo - and they're all Shopify-only.

03

Replaces Google Tag Manager

Paste one script and retire GTM completely. No containers to audit, no per-platform pixels to maintain, no developer needed for updates. Platform SDKs auto-update on the server.

GTM costs 10–40 dev hours/quarter to operate, plus $20+/mo for a server-side container.

What other tools miss.

Standard Shopify integrations lose conversions on manual invoices, post-purchase upsells, and browser/server deduplication. SyncBeacon is built to catch the hidden revenue other stacks drop.

01

Zero-configuration setup

Sync the event_id instantly across browser and server — no hard-coded theme scripts, no checkout.liquid edits, no developer every time you change platforms. Paste one script; Purchase events on thank-you pages pick up the order ID automatically and match your webhook events for pixel + CAPI deduplication.

02

Server-side delivery to six ad platforms

Meta CAPI, Google Ads, Microsoft, X Ads, Snapchat, and Pinterest from one pipeline — with three-layer retry logic so eligible conversions aren’t lost when a platform rate-limits or hiccups.

03

Draft orders & post-purchase upsells

Manual invoices, B2B draft orders, and one-click post-purchase upsells don’t show up in standard pixel setups. SyncBeacon registers draft-order webhooks, detects order-edit revenue increases, and deduplicates every hidden Purchase so you stop under-reporting ROAS.

Under the hood

Why server-side tracking still misses conversions - and what SyncBeacon does differently.

Server-side event capture

Browser pixels miss roughly 30% of purchases. The order goes through Stripe or PayPal, the page reloads, and the pixel never fires. SyncBeacon captures orders from your platform's webhook before any browser is involved - ad blockers, ITP, and redirect gaps become irrelevant.

Google Ads: full click-ID attribution

Google needs a click ID to credit your campaign for a sale. On server-side orders, that ID doesn't travel with the webhook. SyncBeacon stitches the gclid from the original browser session to the server order - so Google attributes the sale correctly instead of marking it 'unknown source'. wbraid and gbraid cover iOS 14+ and Safari.

Delivery that actually retries

Ad platform APIs go down. Rate limits happen. When a delivery fails, most tools log an error and move on. SyncBeacon queues the event and retries up to 24 times over 30 minutes across three independent systems. If it still fails after all that, you get a flag - not a silent gap in your data.

Shared event_id across browser & server

Meta and Google deduplicate pixel and CAPI events by event_id. SyncBeacon assigns the Shopify order ID on thank-you pages and webhooks automatically — no theme edits, no duplicate conversions, no inflated ROAS.

Hidden orders: drafts & upsells

Draft-order invoices and post-purchase upsell apps create revenue standard integrations never see. SyncBeacon listens for draft_orders webhooks and order-edit revenue increases, emitting deduplicated Purchase events your ad platforms can actually optimize on.

Privacy by design

Built for the EU. Ready for every privacy law.

SHA-256 hashing in-browser, zero third-party cookies, consent-signal aware, and a built-in Right-to-Erasure endpoint. GDPR compliance is the architecture - not an add-on.

Common questions

What is SyncBeacon?

SyncBeacon is a server-side conversion tracking platform for e-commerce. One script replaces Google Tag Manager, forwards purchases to Meta, Google Ads, TikTok, and other ad platforms from your store backend, and includes automatic ad pause on stock-outs.

What is server-side conversion tracking?

Server-side conversion tracking sends confirmed purchase events from your store backend to ad platforms like Google Ads, instead of relying only on a browser tag on the thank-you page. The order still counts even when ad blockers, iOS restrictions, or consent limits block the browser tag.

Why is Google Ads missing conversions from my Shopify store?

Usually because conversion tracking depends on a browser tag that is blocked by iOS privacy settings, ad blockers, or cookie consent rejection. The order still happens in Shopify, but Google Ads never receives the event.

How much conversion data do EU e-commerce stores typically lose?

Many EU stores lose roughly 25-30% of browser-tracked conversions, and sometimes more on mobile-heavy or privacy-conscious traffic. Losses vary by market, consent setup, and device mix.

Do ad blockers affect Google Ads conversion tracking?

Yes. Popular blockers and privacy browsers can prevent Google Ads tags and Google Tag Manager from loading, which means purchase events never reach Google even when the sale completes.

Does iOS affect Google Ads tracking on websites?

Yes. Safari and iOS privacy features restrict cookies, limit cross-site tracking, and reduce the reliability of browser-based attribution, especially for mobile shoppers.

Do I need a developer to set up SyncBeacon?

No. Most stores add one script tag and connect a store webhook. Setup typically takes under 15 minutes without custom code.

Your competitors are already recovering those conversions. It takes five minutes to set up and one script to deploy.
