Free Product Manager Invoice Template & Generator

Your invoice needs to show exactly what deliverables you completed during the billing period. Clients want to see if you're billing for sprint planning, feature specifications, user research, stakeholder meetings, or roadmap work. Break out hours by activity type so their finance team can allocate costs properly. If you worked with multiple teams or products, separate those lines. Companies often need this detail for internal cost tracking and budget allocation across different product lines.

Most product management contracts work on monthly retainers or weekly rates. Some clients do milestone payments tied to product releases or completion of specific phases like discovery or beta launch. Net 30 is standard but you can often negotiate Net 15 for smaller companies. Getting a 25-50% upfront payment is reasonable for new client relationships or project-based work.

Send your invoice the day your billing period ends, not a week later. Product managers often get busy with launches and forget to invoice promptly. Late invoices get pushed to the next payment cycle. Also, attach your completed deliverables or link to the documentation you produced. Finance teams process invoices faster when they can immediately verify the work happened.
