Your client needs an organisation answer that sits outside your mandate.
Between signing and closing, or inside a restructuring, the structural question is your client’s problem and not your remit. If you refer it to a large firm, your client usually gets a team and a programme along with the answer. Our price is fixed and published on this site, the work takes a few weeks, and we do not try to sell your client anything after it.
Most referrals start with an OD Opportunity or an OD Verdict.
