If you're a Salesforce consulting partner considering an overflow delivery relationship — bringing in outside capacity or a niche skill like Marketing Cloud or CPQ without adding headcount — the partner you pick reflects directly on you. Your client doesn't see the arrangement; they see the outcome. Here's what's worth asking before you commit.
1. Will their name ever appear in front of my client?
This should be a flat no. A real overflow partner works as an extension of your delivery team, not a competing brand. If there's any ambiguity in how they answer this, that's the answer.
2. Are their consultants actually certified for the cloud in question, or learning on your project?
Ask which credentials the specific people on your engagement hold — not the firm in aggregate. "Certified before we start, not while billing you" is the bar worth holding any partner to.
3. What's their actual delivery track record, by industry?
Generic "we do everything" positioning is a yellow flag. Ask for specifics — which industries, what kind of engagements, and whether they can speak to trade-offs, not just outcomes.
4. How fast can they actually plug in?
A long onboarding process defeats the purpose of overflow capacity. A short scoping call followed by rapid staffing is the model to look for — weeks of internal process before anyone touches your client's org is a warning sign.
5. What does their engagement structure actually look like?
Dedicated resource, project-based, or managed retainer — and can they flex between them as the engagement changes? A partner locked into one model regardless of what you actually need is optimizing for their own convenience, not yours.
6. What happens to governance and release discipline once they're in your client's org?
Sandbox strategy, release management, and documentation shouldn't depend on the individual consultant remembering to do them. Ask how it's built into their process, not just promised.
The short version
The right overflow partner should make your firm look more capable to your client, not introduce risk you now have to manage. If a potential partner can't answer these six questions specifically and quickly, that's worth treating as data.
