Offline conversion tracking for B2B SaaS: send the qualified demo and the paid plan, not the signup

SaaS companies often think they don't have an offline conversion problem, because everything happens online. Then they look at where the money actually decides itself: the sales call, the trial that turns into a plan, the contract that closes in a CRM.

Here's the shape. An ad gets a click. The click becomes a signup or a demo request. Then a sales-assisted process follows: qualification, a demo, a trial, a negotiation, a signed plan. The ad platform sees the signup. Everything that decides revenue happens in the CRM.

The result is familiar: campaigns optimise for signups, and signups are cheap. So the platform finds lots of people who'll sign up for anything. Cost per signup looks good. Revenue doesn't.

What to send, roughly in order.

The qualified lead: a person your sales team accepted. It filters most of the junk.

The demo held: an actual conversation happened. Strong signal, moderate volume.

The trial activated or the plan paid: the truest, with the value. If your sales cycle is long, this may arrive too late for some platforms, so send the earlier stages too.

Two constraints matter especially for B2B.

The window. LinkedIn accepts conversions up to 90 days old, Google ignores uploads more than 90 days after the click, and Meta rejects events sent more than 7 days after they happened. A six-month enterprise cycle blows past all of them, so send the stages that fall inside.

The match key. LinkedIn matches on a hashed email, the li_fat_id, or a name with company or job title. It doesn't match on phone. So collect a work email.

A made-up example. 500 signups a month. 120 qualified. 60 demos held. 18 paid plans. Optimise on signups, and the platform chases 500. Optimise on demos held, and it chases the 60, each of them a real conversation.

It's worth separating two SaaS motions, because they need different signals.

Sales-led: the person requests a demo, talks to sales, and a contract follows. Send qualified, demo held, and closed-won with the value. The CRM is the source of truth.

Product-led: the person signs up and uses the product, and a plan is bought later, often without a human. The interesting signals are usage-based: activated, invited a teammate, hit a limit, upgraded. Those need to reach the ad platform as events with the person's email attached.

Many companies are both. Then map each stage to its own event, and be careful that a self-serve upgrade and a sales-closed deal don't both count for the same customer.

A quick cheat sheet for windows. Meta: send the event within 7 days of it happening. Google: within 90 days of the click. LinkedIn: conversions up to 90 days old. If your cycle is longer, send the earliest stage that's still a good signal.

What's your sales cycle, and which stage are you sending?
