How to rebuild SaaS marketing attribution the CFO will sign off.

SaaS marketing attribution breaks for one boring reason. Every ad platform claims the same conversion, so the channel totals add up to more revenue than the company actually booked.

Google says it drove the deal. LinkedIn says it did too. So does the retargeting campaign and the email tool. Add the platform reports together and marketing is suddenly claiming 140% of pipeline. A CFO sees that once and quietly discounts every marketing number that follows, forever.

Why platform attribution always over-counts

Each platform is built to take credit. That is its job, it justifies its own spend. None of them can see the others, so none of them can de-duplicate. You are asking four players to referee their own game and then adding up four biased scores. The total is fiction and finance can smell it.

Once the data lives in the warehouse, the model is a choice, not a default someone else made for you.

The attribution model we actually trust

Multi-touch, weighted to the touches that move deals forward, with the assumptions written down in plain English. Not last-touch, which hands all credit to the final click and starves the channels that created demand. The honesty matters more than the math. A model that says "here is what we credit and here is what we cannot see" beats a model that projects false precision. Finance trusts stated uncertainty far more than confident nonsense.

There is a simple way to know whether your attribution is real.

So would your attribution survive a finance review?

Sit your marketing numbers next to the finance numbers and see if they reconcile. If marketing claims more pipeline than the company booked, you have a platform problem, not a performance problem. Fix the referee before you argue about the players. The rebuild is unglamorous and it is the highest-leverage thing most SaaS marketing teams are not doing.
