Telling your client
Pros
- You never have to manage a secret. A client who finds out on their own wonders what else they don't know.
- It passes procurement. Enterprise and regulated clients often have to approve everyone who touches their code or data.
- It shows depth. "We bring in specialist engineers for builds like this" sounds like a well-run agency, not a thin one.
- The partner can work in the open. Engineers can answer technical questions on calls without a cover story.
Cons
- Some clients will ask why they aren't paying the partner directly.
- Your markup gets more scrutiny.
- It opens a door to the partner. A non-solicit closes it, but only for the term you agreed.
