i've worked with multiple clients til now and the pattern i see is the usually just need simple, few data in quantitative but they want it to be clear like what does the data stands for and how it'll help them with their issues. i usueally just keep it short with things like records processed, duplicates removed, companies scored, contacts enriched, emails found and validated, and also the final number of contacts ready for outreach. for reporting, i'd start with excel/clay exports and only build dashboards when it's an ongoing engagement plus icypeas to report on validation results and chatgpt to work for the copy and all will be exported to pdf format
