Dual-Sort Running Totals Tool
TL;DR
Dual-sort data analysis tool for mid-size company accountants that applies two simultaneous sort rules (e.g., date + region) to 100K+ row CSVs while auto-calculating running totals in real time so they can generate error-free financial reports 5x faster without Excel crashes or manual workarounds.
Target Audience
Data analysts using Power BI or Excel for inventory forecasting
The Problem
Problem Context
Data analysts and accountants track daily forecasts in large spreadsheets or databases. They need to sort data by two specific rules at once (e.g., date + category) while calculating running totals. This helps them spot trends and make decisions faster.
Pain Points
Their current tools (Excel, Google Sheets, or databases) crash when applying both sorting rules simultaneously. The system throws memory errors, forcing them to restart or simplify their analysis. Manual workarounds like splitting data into smaller sheets waste hours and introduce errors.
Impact
Crashes delay reports, which slows down business decisions. Missed trends or errors in forecasts can cost thousands in lost revenue or incorrect planning. The frustration of repeated crashes disrupts their workflow and reduces productivity by 20% or more.
Urgency
They need this fixed now—every day they wait, they fall further behind on critical reports. The problem isn’t just annoying; it’s blocking their ability to do their job effectively. Temporary fixes (like smaller datasets) don’t solve the root issue.
Target Audience
Data analysts, financial planners, and accountants in mid-size companies (10–500 employees) who work with large datasets daily. Also affects project managers, supply chain analysts, and anyone who relies on sorted running totals for forecasting.
Proposed AI Solution
Solution Approach
A web-based tool that lets users upload their data (CSV, Excel, or direct database connection) and apply two sorting rules simultaneously without crashes. It calculates running totals in real time, even for large datasets (100K+ rows), and displays results in an interactive table.
Key Features
- Running Total Calculator: Auto-computes cumulative sums for any column while respecting both sort orders.
- Sandbox Mode: Test calculations on a copy of your data to avoid accidental overwrites.
- Export Options: Download results as CSV, PDF, or shareable link for reports.
User Experience
Users drag-and-drop their data file into the tool. They select their two sort criteria (e.g., ‘Month’ and ‘Product Category’) and choose the column for running totals. The tool processes the data instantly, showing sorted results with cumulative sums. They can refine sorts, export, or share—all without leaving the browser.
Differentiation
Unlike Excel or databases, this tool is *built for dual-sort + running totals- and won’t crash. It handles large datasets natively (no ‘out of memory’ errors) and requires zero setup. Competitors either lack this feature or force users to split data manually, which is error-prone.
Scalability
Starts with single-user plans ($29/mo) but scales to team plans ($99/mo for 5+ users). Adds API access for firms that need to integrate with their existing tools. Future features: scheduled reports, team collaboration, and custom calculation formulas.
Expected Impact
Users save 5+ hours/week by eliminating crashes and manual workarounds. Reports are generated faster and more accurately, leading to better decisions. The tool pays for itself in the first month by preventing downtime and errors.
