Invoice clients for product strategy, roadmap work, and product management consulting. Professional invoices from Tidybill.
A product manager invoice covers work defining, prioritising, and overseeing the development of digital products. Contract product managers are brought in to fill gaps during team transitions, drive specific product initiatives, or coach in-house product teams. Work includes user research, competitor analysis, writing product requirements and user stories, managing product backlogs, collaborating with engineering and design teams, defining product metrics, and presenting to stakeholders. Unlike engineers who produce code, product managers produce decisions, documentation, and alignment, so invoices should describe the outcomes enabled (product roadmap created, feature set launched, team process improved) rather than just time spent. Day rate contracting is the most common billing model for embedded product management roles.
| Service | Typical Rate | Unit |
|---|---|---|
| Product management (day rate) | 600 | day |
| Product strategy and roadmap development | 3000 | project |
| User research and discovery (per round) | 1500 | project |
| Product coaching (individual or team) | 300 | session |
| Product audit and recommendations | 2000 | project |
| Stakeholder workshop facilitation | 800 | session |
For embedded contract roles, invoice weekly or bi-weekly with a brief description of work completed: ceremonies attended, documents produced, decisions made, and features shipped. For project-based engagements (product audits, discovery sprints), invoice at the end of the engagement with a summary of deliverables. Reference the product name and engagement period on every invoice.
