I found this exact problem in my own account.
I run Google Ads for my own businesses. After Google's tracking changes, I found my account was firing its conversion data in the wrong order and quietly misreporting everything. I caught it, fixed it, and watched the wasted spend drop.
That is the same process I run on your account. No bloated agency, no junior handed your account, no long contract. Just the person who does the work, finding your leaks and stopping them.
Because I keep it lean, I move faster and cost less than the agencies, and you are never locked in.
