Paid discovery vs. free proposals: what agencies should weigh
Paid discovery can improve the quality of an agency’s scope, but it changes the buying decision and may lengthen the path to a signed project.
A practical call review can reveal where qualification, discovery and next steps break down before an agency changes its pitch or process.
An agency can lose a deal well before a prospect says no. The call may have focused on services before confirming fit. The buyer may have hinted at a business constraint that went unexplored. Or the conversation may have ended with a vague promise to follow up.
Reviewing sales calls helps owners find these points of friction. The goal is not to grade a rep’s personality or hunt for a magic closing line. It is to identify where the conversation stopped helping the buyer make a decision, then improve the process.
Tim Kilroy - WTF Growth lists Call Lab and Discovery Lab among its diagnostic tools, and offers SalesOS for building repeatable sales processes. The specific review method below is a practical way to examine calls; it does not depend on a particular tool or interface.
Pick three to five recent calls that ended in different ways: a win, a loss and a stalled opportunity, if available. Include calls from more than one person if you are training a team. A single call can expose a mistake. Several calls can show whether the same problem keeps appearing.
Use recordings only when you have the necessary permission and follow the rules that apply to your business and the prospect. If a recording is not available, review contemporaneous notes, but treat conclusions about tone or conversational dynamics as uncertain.
Before listening, write down what you know about the opportunity: who attended, what the agency believed the prospect wanted, and what happened next. Do not use the eventual outcome as proof that every choice on the call was right or wrong. A win can still contain weak discovery; a loss can happen despite a sound conversation.
For each pass, capture a timestamp or short quotation, then write two notes: what happened and what it may mean. “Prospect says the current campaign is not converting; rep moves to agency credentials” is evidence. “Rep does not understand performance marketing” is an interpretation.
Keep the interpretation provisional. Ask what question could have tested it. In this example, the rep might have asked where conversion breaks down, what the prospect has already tried and how the result is measured. That turns a broad judgment into a practice point.
A simple score can help compare calls: mark each area as clear, partial or missing. Use the labels consistently, but do not mistake the score for the diagnosis. The specific moment and its business consequence matter more than a total.
After reviewing the sample, look for repeated friction. Are reps moving to solutions before they understand the problem? Do they leave decision-makers or buying constraints unaddressed? Do prospects raise the same concern without getting a clear response? A repeated pattern is a better candidate for process improvement than one awkward exchange.
Choose one change to test. It could be a discovery question, a qualification checkpoint or a clearer way to confirm the next step. Write down when the team should use it and what evidence would show that it helped. Then review another small batch of calls. Avoid changing the pitch, qualification criteria and follow-up routine all at once; otherwise, it becomes hard to tell what changed the conversation.
Share call excerpts with the team in a coaching setting, focusing on the decision and its effect rather than embarrassment. Owners reviewing their own calls should apply the same standard. A sales process should make useful behavior easier to repeat, not turn every conversation into a script.
That discipline is the practical value of an agency sales call audit. It makes weak qualification, missed diagnostic signals and vague closes visible. Tools such as Call Lab and Discovery Lab sit within WTF Growth’s diagnostic offer; the work remains the same: listen closely, separate observation from assumption, and use the evidence to refine a repeatable sales process.
Paid discovery can improve the quality of an agency’s scope, but it changes the buying decision and may lengthen the path to a signed project.
Use a business-first sequence to uncover what a prospect needs to change before you discuss scope, tactics or price.
Before handing sales to a rep, agency owners should be able to explain how a qualified opportunity moves from first conversation to signed work.
