BILKCT.

BILKCT is a simple, private tool for tracking project costs and revenue. Built for freelancers, individuals, and small teams, it helps you understand each project's profit and cost structure at a glance. Your project data is stored on your device, and no account is required to use the app.

Five-tab workflow:

• Dashboard: Monthly profit, margin, alerts, project rankings, and recent ledger entries in one view.
• Projects: Create project profiles and manage costs and revenue for each engagement.
• Ledger: Review every cost and revenue entry across projects, filter by month, and edit records.
• Insights: Analyze cost structure with charts and compare this month with last month.
• Me: Read the user guide and disclaimer, export a local backup, load sample data, or clear records.

Key features:

• Record costs by project across multiple categories
• Enter revenue manually for each project
• Automatic profit and margin calculations, where margin = (Revenue - Cost) / Revenue
• Cost-structure breakdown with a donut chart and share percentages
• Six-month trend chart
• Month-over-month project comparison
• One-tap sample data to explore the app instantly
• Local storage with export and backup

BILKCT is a personal bookkeeping aid. Calculations are based on the data you enter and do not constitute financial, tax, audit, or investment advice.
