Offline conversion tracking

When the sale happens on a call, in a CRM or on an invoice, offline conversion tracking still connects it to the ad.

Flat monthly price, no revenue tax
No annual contract
Tracking starts the minute the snippet is live

Many valuable sales never touch a checkout page: a deal closed on a sales call, an invoice paid by bank transfer, a customer who walks in after seeing an ad. Offline conversion tracking records those sales against the person who generated them and reports them to your attribution tool and ad platforms.

It works by keeping the link between the person and their ad click. When the lead first arrives, store their click ids and identifiers. When the deal closes, look up the person by email or phone and send the conversion with the most recent click id and hashed customer data. The platform matches it to the click and credits the ad.

The problem

Why this matters for your ad budget

Offline sales are often the biggest ones, and the hardest to attribute. Without them, your ad reports undercount the most valuable outcomes.

Bringing them in and sending them back to ad platforms closes the loop.

Why BrainyMetrics

From theory to your own numbers

Everything in this guide is built into BrainyMetrics, working on your real ads, leads and sales.

Without BrainyMetrics

With BrainyMetrics

Meta, Google and TikTok each claim the same sale, so platform totals add up to more than your bank account.

Each sale is counted once, from your own checkout data, and reconciled against what each platform claims.

Analytics gives the last click all the credit, so the ads that start journeys look like they lose money.

Seven attribution models are computed for every conversion, so you can compare first click, last click and everything between.

Phone calls and booked calls are a black box. You know they happened, not which ad caused them.

Calls and bookings are matched to the visitor's session and the ad behind it, then tracked through qualified and closed.

Ad blockers, Safari and cross-domain checkouts quietly break your data.

A first-party tracking subdomain, server-set cookies and cross-domain linking keep journeys intact.

Spend lives in one tab, revenue in another, and ROAS is a spreadsheet you rebuild every Monday.

Spend syncs hourly and sits next to attributed revenue, so ROAS, CPA and profit are on every row, down to the ad.

Ad algorithms optimise on the few conversions their pixel happens to see.

Real purchases and leads are sent back to the ad platforms' conversion APIs, deduplicated against the pixel.

Stop guessing which marketing pays.

Frequently asked questions

Common questions about Offline conversion tracking, setup and pricing.

The fastest answer is your own data

Create an account, install the snippet and see how BrainyMetrics handles your real traffic.

Get started

How long after the click can I upload?

Platforms limit this: Google Ads accepts clicks up to 90 days old, Meta generally 7 days for Conversions API events.

How long does setup take?

The basics take minutes: paste the snippet, connect your checkout or funnel builder, and connect your ad accounts. The setup checklist in your dashboard ticks each step off as data arrives, so you always know what's left.

Do I need a developer?

Usually not. The snippet can go in through Google Tag Manager, WordPress or your funnel builder's tracking code settings, and most revenue sources connect with a click or a webhook URL you paste. The developer guide covers the JavaScript and server API if you do have a developer.

Does the price go up as I grow?

No. Plans are a flat monthly or yearly price. We never bill a percentage of revenue or ad spend, and you can switch, pause or cancel from the Billing page without a call.

Does tracking stop if I hit a plan limit?

No. Plans limit dashboard modules and things like integrations or workspaces; tracko.js, webhooks and syncs keep collecting data, so nothing is lost if you upgrade later.

Is it privacy friendly?

Yes. BrainyMetrics supports consent modes, works with your consent banner, respects Global Privacy Control and handles sensitive form fields strictly. Data is first-party: it belongs to your workspace, not an ad network.
