You stay the client's contact
I don't talk to your client unless you want me on the call, and I don't pitch them anything. White label is fine.
You keep the client relationship and the invoice. I build to the spec, in whichever platform you've already scoped it in, and hand back something your team can maintain after I'm gone.

Send the scope and I'll come back with the questions that matter before I start, not after. No daily check-ins needed.
n8n, Make.com, Zapier, or custom JavaScript and Apps Script. If you've already sold it in one, that's the one I build in.
Notes on how it runs, what breaks and where the credentials sit, written for whoever on your team inherits it.
Scoped in defined chunks rather than one number for a vague whole, so you can quote your client with a margin you can hold.
If the spec has a hole in it or the platform is wrong for the job, you hear that before the work starts.
Before going independent I spent three and a half years running operations at a digital agency in Pakistan, moving from SEO manager to general manager. Delivery, hiring, business development, the lot. I know what it costs you when a subcontractor needs managing, misses the brief, or disappears halfway through a build.
The clearest example of what I actually ship is a production order pipeline for a subscription kitchen in Japan. Four to five hours of manual work a week, down to about thirty minutes, live since March and running without me since June.
Send the spec. I'll tell you whether it's a fit, what I'd need, and roughly how long, usually the same day.
