# Execution Scorecard: Blended retainer-plus-usage billing for agencies

Score: 40/100

Tier: Research first

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 Launch Plan
- **2026-06-17 / 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.
- **2026-06-20 / 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.
- **2026-06-24 / 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.
- **2026-07-01 / 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.
- **2026-07-08 / 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.
- **2026-07-17 / 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.
