Execution Scorecard

Blended retainer-plus-usage billing for agencies

Blended retainer-plus-usage billing for agencies scores 40/100 for execution readiness. The recommended next step is Recruit eight agencies, model one real hybrid-pricing client each, generate a month of consolidated invoices, and check accuracy against their hand-built spreadsheet plus willingness to switch.

Bottlenecks

Billing accuracy is unforgiving and a single miscalculated invoice can lose an agency's trust permanently.
Stripe Billing and similar incumbents already handle usage and subscriptions, narrowing the differentiation to agency-specific blending.
A broad AI assistant can flatten differentiation unless the wedge is painfully specific.
The first release can become a generic dashboard if the job is not named tightly.
Needs real buyer access, not only desk research.
Needs proof of budget or repeated urgency.
Needs a crisp wedge before broad product work starts.

Accelerators

Can talk to the buyer before writing much code.
Can ship a narrow first-win demo quickly.
Can use local-first research artifacts to keep validation moving without a large team.
Use specificity as the wedge: one buyer, one workflow, one measurable result.
Show proof earlier than broad competitors with before-and-after examples and small pilot data.
Keep implementation lighter than incumbent suites or generic AI assistants.
Concierge review or paid template

Dated Plan

First 30 days to evidence.

The plan starts from build time and should be re-exported when the founder chooses a real start date.

1. Frame the wedge

Write the one-sentence promise and test it in the strongest channel.

Proof: Recruit eight agencies, model one real hybrid-pricing client each, generate a month of consolidated invoices, and check accuracy against their hand-built spreadsheet plus willingness to switch.

2. Interview 10 people who match the buyer persona.

Create the lead magnet and use it to recruit interviews.

Proof: Problem resonance: 5+ calls or 10+ detailed replies.

3. Ship a clickable demo or concierge workflow that produces the first useful artifact.

Build the smallest demo that proves the first win.

Proof: Activation: 25% of demo visitors complete the first-win path.

4. Run one paid pilot or collect explicit pricing objections before automating the rest.

Delete any report section that feels generic before building.

Proof: Commercial pull: 3 paid pilots, LOIs, or concrete procurement next steps.

5. Promote to a deeper build plan only after the wedge survives validation.

Run the lead magnet and first-win demo tests.

Proof: Fewer than five qualified buyers agree to discuss the workflow after targeted outreach.

6. Execution checkpoint 6

Promote to deeper implementation only once the wedge survives interviews or paid-pilot outreach.

Proof: Promote to a deeper build plan only after the wedge survives validation.
