FAQ
What type of data can you work with?
Sales, marketing, customer, financial, operational, or survey data — in CSV, Excel, or via SQL database access. If you're unsure whether your data fits, message me before ordering and I'll confirm.
How will you deliver the analysis?
As a written report (PDF or Excel) with charts, key findings, and a plain-language summary of what the data shows. Standard and Premium tiers include a Python/Jupyter notebook if you want to see the underlying work.
Do I need technical knowledge to understand your report?
No. Every report is written for decision-makers, not just analysts — the goal is clear takeaways you can act on, not raw output.
Can you help me clean or preprocess my data?
Yes, data cleaning is included as part of the analysis process in all tiers.
Can I request changes after delivery?
Yes — revisions are included per package (1 on Basic, 2 on Standard, 3 on Premium). Let me know exactly what needs adjusting and I'll turn it around quickly.
What if my dataset is larger than the tier limit?
No problem — message me before ordering and I'll recommend the right package or a custom quote.
