Invoice clients for CRO audits, A/B testing programmes, and landing page optimisation. Professional invoices from Tidybill.
A conversion rate optimisation (CRO) consultant invoice covers services improving the percentage of website visitors who take a desired action. CRO work includes website and funnel audits, user research (heatmaps, session recordings, surveys), A/B and multivariate testing, landing page redesign, checkout optimisation, and ongoing experiment management. CRO is typically project-based (audit and recommendations) or retainer-based (ongoing testing programme). Tool costs (Hotjar, VWO, Optimizely) are significant and may be passed through. Results from CRO can be demonstrated with conversion data, making invoices easy to justify with performance reports.
