Managing Multiple Stakeholders on One Client Account
Short answer: Multi-stakeholder accounts fail in two specific ways — contradictory feedback that nobody reconciles, and single-threading, where your entire relationship runs through one person who then leaves. Both are structural rather than interpersonal. Map who does what, route decisions through a named approver, and deliberately build a second relationship before you need it.

Map the four roles
On any account with more than one contact, work out who occupies each:
The champion — chose you, defends the budget internally, knows what you've delivered
The approver — whose sign-off actually closes a deliverable. Sometimes the champion, often not
The operator — day-to-day contact, sends the assets, answers the questions
The economic buyer — controls the money, may rarely appear until renewal
Most agencies know the operator well and the economic buyer barely at all. That's the wrong way round for retention, because the person who decides whether you're renewed may have almost no direct experience of your work.
The single-threading problem
When a client-side champion leaves their company, the probability of the account churning within twelve months rises sharply — and rises further when the departing contact is senior.
The mechanism is simple. Their replacement inherits your invoices and none of your history. They have no memory of the problem you solved, no relationship with your team, and often their own preferred agency. To them you are an unexamined line item with a cost.
Treat every new stakeholder as a fresh pitch, because from their side that's exactly what it is.
How to stay multi-threaded
Get a second person on your side known to them — not just the account lead
Get a second person on their side known to you, ideally closer to the money
Make sure the record of what you've delivered is visible to anyone on their side, not carried in one person's memory
When a new stakeholder appears, book a proper introduction rather than letting them absorb you through email threads
That third point does most of the work. A new stakeholder who can see twelve months of delivered work forms a very different view than one who sees only an invoice.

Routing decisions
Contradictory feedback is a routing failure, not a client failure.
Name one approver per deliverable type. Design decisions go to one person, commercial decisions to another. Everyone else comments.
Require feedback to be consolidated on their side. If contradictory notes arrive, send them back rather than choosing — choosing means you own an outcome nobody agreed on.
Put requests through one channel. Three stakeholders emailing three people at your agency guarantees dropped work and duplicated effort.
Give everyone the same view of status. Most "why wasn't I told" comes from stakeholders receiving different updates at different times.
Frequently asked questions
How do I handle conflicting feedback from client stakeholders?
Send it back to be reconciled on their side rather than choosing between the notes. Choosing means you own an outcome the client never agreed on, and you'll be revisiting it.
What happens when my main client contact leaves?
Churn risk rises sharply. The replacement inherits your invoices without your history. Treat them as a new pitch — book a proper introduction and make sure they can see the full record of what's been delivered.
How do I avoid single-threading a client relationship?
Build a second relationship on both sides before you need it, and make sure the record of delivered work is visible to anyone on their side rather than held in one person's memory.
Should all stakeholders get the same updates?
Yes for status. Most "why wasn't I told" friction comes from different people receiving different information at different times. Detail can vary; the underlying picture shouldn't.
The short version
Map champion, approver, operator and economic buyer. Route decisions through named approvers. Build a second relationship on both sides before the first one leaves — and make sure your delivery record survives that departure.
