FAQ
Do I need to contact you before ordering?
I recommend contacting me first, especially for Standard or Premium projects. I can review your files, goals and required features to make sure the project fits the selected package.
What files can you work with?
I primarily work with Excel (.xlsx, .xls) and CSV files. I can also combine multiple files or work with structured exports from accounting, ERP or business systems.
Will I receive the source code?
Yes. Source code can be included depending on the selected package and project scope. Please mention this before ordering if source code delivery is important for your project.
Can you clean and organize my data?
Yes. I can clean, restructure and standardize your Excel or CSV data before building the app. More complex or highly inconsistent datasets may require the Data Cleaning extra.
Can you combine multiple Excel or CSV files?
Yes. Standard and Premium projects can combine multiple files into one structured financial application. The number and complexity of files may affect the final scope.
Is online deployment included?
Deployment depends on the selected package. Online deployment can also be added as an extra if you want the application accessible through the web.
Can the app include custom calculations?
Yes. I can implement custom KPIs, margins, profitability calculations, ratios, budget comparisons and other business-specific formulas based on your requirements.
Can users upload new Excel or CSV files to the app?
Yes. File upload functionality can be added so users can update the application with new Excel or CSV data without modifying the source code.
Can the app export reports or data?
Yes. PDF or Excel export functionality can be added depending on the package or as an extra service.
10. Is an API or database connection included?
This Gig is primarily designed for Excel and CSV projects. API or database integrations are available for more advanced projects and may require a custom offer or my Financial Analytics App service.
