FAQ
Is this service only for dashboards?
No. I also clean data, write SQL, define KPIs, analyze business performance, and repair reports. Your deliverable can be a prepared dataset, reusable code, findings report, or an agreed reporting solution.
Which package should I choose?
Basic covers one small task. Standard covers one dataset and one business question, with up to five metrics. Premium covers up to three related tables and ten metrics, with a report and up to three charts. Send a sample before ordering so I can confirm the scope.
Can you help define our KPIs?
Yes. We can define each key performance indicator’s purpose, formula, data source, reporting period, and exclusions. I validate calculations against agreed examples or reference totals. Business targets require your input.
Can you fix existing SQL queries or reports?
Yes. I investigate incorrect totals, duplicate counts, broken joins, calculation errors, and reporting issues. Share the current result and expected result. I will review the issue before confirming the repair scope.
Can you work with messy or incomplete data?
Yes. I check missing values, duplicates, inconsistent formats, and invalid records. We agree on cleaning rules before changes. I document unresolved issues and explain how they affect the findings.
Are dashboards, warehouses, and pipelines included?
The packages include only their stated deliverables. Dashboards, full warehouse builds, pipelines, and migrations require a separate quote. Premium includes report charts, but these do not automatically include an interactive dashboard.
What files will I receive?
You receive the files agreed before the order starts. These may include a prepared dataset, SQL queries, Python scripts, KPI definitions, and a findings report. Custom Power BI or Tableau projects include editable files where applicable.
How do you check the results?
I use checks suited to the task, such as row counts, duplicate checks, relationship checks, and comparisons with reference totals. I document assumptions and limitations so you can understand and reuse the work.
What do revisions cover?
Revisions cover adjustments within the agreed scope. New data sources, business questions, metrics, report pages, or features require additional scope. Please provide clear, consolidated feedback.
What do you need before starting?
Send your business question, sample data, current tools, required output, budget, and deadline. Include metric definitions and expected results where available. Remove sensitive information from samples. Do not send passwords or secret keys.
