The Financial Question to Ask Before Your Next Proposal Goes Out

Before the next proposal leaves your inbox — one question that changes everything.
"At our proposed fee, can we genuinely deliver what this client needs and still make a 55% gross margin?"
Not: can we do the work. Not: will they pay the fee. Can we do the work at the margin we need to run a sustainable business.
Most agencies skip this entirely. They say yes to the work, figure out the economics later, and then wonder six months into a retainer why that client is the most stressful relationship in the business.
"The best time to have the financial conversation about a client is before they become one."
Why This Keeps Getting Skipped
There's a moment in every new business conversation where the work feels exciting, the client feels right, and saying yes feels easy. That's exactly when the financial check gets skipped.
The brief looks deliverable. The fee looks reasonable. And the detailed margin calculation feels like something you can sort out once it's signed.
Six months later, that client is the one eating the most hours, paying the least per hour, and generating the most internal stress. Not because the relationship went wrong — because the economics were never right to begin with.
The fix isn't better account management. It's a ten-minute check before the proposal goes out.
Three Checks to Run Before Every Proposal
Check one: What is the realistic hourly rate after all delivery costs?
Take the proposed fee. Divide by estimated hours. Multiply by 0.85 — to account for the hours that always run over.
If that effective rate comes out below £75 fully loaded, the scope needs tightening before anything is agreed. You're not being precious about margin. You're protecting the team's time and the business's sustainability.
Check two: Does the brief match the budget?
If the expectation is full SEO, paid media, content, reporting and strategy calls for £1,500 a month — that isn't a pricing conversation. That's a fundamental mismatch that will not improve after the contract is signed.
Better to surface it before the proposal than to discover it in month two when resentment is already building on both sides.
Check three: What happens in month three when the scope expands?
Every client expands the brief. Every single one. The question isn't whether it will happen — it's whether you've priced for it or whether you're assuming goodwill will hold.
If your contract has no change order clause, scope expansion is essentially free from the client's perspective. That's a commercial decision you've made by default rather than by choice.
Your Checklist
Review your last three new client proposals — did you model the margin before sending?
Calculate the effective hourly rate on any live proposals — fee ÷ estimated hours × 0.85
Check whether brief expectations match the budget — flag any mismatches before they become contractual
Set a minimum margin threshold — no new client below 50% gross margin on the proposal
Add a change order clause to your standard contract if one doesn't already exist
Three Things to Do This Week
1. Apply the margin test to every live proposal right now. If any don't hit 50%+ gross margin at the proposed fee — reprice or rescope before it goes out. Not after. Before.
2. Have the brief vs budget conversation early. "Based on what you've described, here's what we can deliver at that budget — and here's what would require additional investment." That conversation before the contract is infinitely easier than the one you'll have after month two.
3. Set a written minimum margin threshold as policy. No new client below X% on the proposal. Make it a rule, not a case-by-case judgement call made under commercial pressure. When it's written down it stops being a negotiation every time.
The agencies that grow without the stress aren't turning away more work. They're just making better decisions about which work to take — and at what terms.
That starts before the proposal goes out.
