I will build an offline inventory control dashboard for your business
Xavier L.
About this gig
Too much stock ties up cash. Too little stock loses sales.
My name is Xavier Loeb, founder of XL Data Express. I will build a private offline inventory control dashboard for retailers, distributors and e-commerce businesses that need to see what moves, what stalls and where capital is tied up.
Using an anonymized Excel, CSV or Parquet structure, I configure local analysis of stock levels, product rotation, slow-moving items, low-stock risks, category performance, stock value, ABC/Pareto concentration and trends by period or location when those fields are available.
Your files stay on your computer. No public cloud upload or recurring dashboard subscription is required.
You receive:
- Offline inventory dashboard
- Data mapping and validation
- Product, category and location filters
- KPIs, rankings and visual reports
- Parquet support for larger files
- Branding and onboarding by package
This is decision support, not an ERP replacement or automatic stock updater without a compatible data export. Before ordering, send only a column list or anonymized sample. A business-use license is included; source code and resale rights require a separate quote.

I am an 11th-term Economics student at UAM Azcapotzalco and a data analyst experienced in pharmaceutical-market and financial analysis. Since 2025, I have built dashboards, cleaned databases and automated reports using Power BI, Excel, Power Query, Python and SQL.
Through XL Data Express, I create offline BI tools that turn Excel and CSV files into clear KPIs, filters and visualizations. I also repair AI-generated spreadsheets and validate formulas.
I communicate in Spanish and English and define project scope clearly. Please contact me before sharing confidential information.
FAQ
Who is this service for?
Retailers, wholesalers, distributors, manufacturers and e-commerce businesses that export inventory or product data to Excel, CSV or Parquet.
What problems does it help identify?
Depending on the available fields: excess stock, low-stock risk, slow-moving products, product concentration, stock value and performance by category, period or location.
Does it replace an ERP or point-of-sale system?
No. It is an offline analytical layer that works with a compatible export from your existing systems.
Does it update inventory automatically?
Not by default. The standard service analyzes uploaded local files. Automated refresh requires a compatible local data source and a separate scope review.
Which formats are supported?
Excel, CSV and Parquet. Parquet is recommended for larger tabular datasets when compatible with the client's workflow.
Will my inventory data be uploaded to a public cloud?
No. The configured dashboard runs locally. Use anonymized information during the compatibility review.
Which columns are normally useful?
Product ID, description, category, current stock, units sold, date, unit cost or stock value, location and reorder threshold. The exact model depends on your available data.
Is source code included?
No. The package includes implementation and a business-use license. Source code and resale rights require a separate quote.
