Invoice clients for growth experiments, user acquisition, and conversion optimisation work. Professional invoices from Tidybill.
A growth hacker invoice covers growth marketing services focused on rapid experimentation across acquisition, activation, retention, and referral channels. Growth hackers use data-driven testing (A/B tests, funnel analysis, channel experiments) to find scalable growth opportunities for startups and growth-stage businesses. Work includes funnel analysis, A/B testing, landing page optimisation, referral programme design, email re-engagement campaigns, and viral loop development. Growth hackers typically bill on a project or sprint basis, with clear deliverables per sprint. Some work on retainer with regular experimentation roadmaps. Performance-based bonuses tied to growth metrics are an alternative billing model.
