Financial Tracker — by The Agent Ledger

Just deliver this skill to your agent. One paste, and your agent becomes your personal CFO — no spreadsheets, no accounting software to learn. Your agent reads the instructions and handles the rest.

Track every dollar in and out of your solo business. Monthly P&L snapshots, revenue goal progress, cash flow flags, and tax estimate tracking — all maintained in plain text files your agent understands.

What This Skill Does

Configures your agent to act as a lightweight CFO for your solo business:

1. Income Logging — Record revenue entries with source, amount, date, and category
2. Expense Logging — Track business expenses with vendor, amount, purpose, and tax status
3. Monthly P&L — Generate profit-and-loss summaries on demand or on a schedule
4. Revenue Goal Tracking — Monitor progress toward monthly and annual income targets
5. Cash Flow Flags — Surface warning signs (slow months, rising costs, income concentration risk)
6. Tax Estimate Tracking — Rough quarterly self-employment tax estimates based on net income
7. Year-to-Date Snapshot — Running YTD revenue, expenses, and net income at any time

---

Quick Start

Tell your agent:

"Read the Financial Tracker skill. Set up my finance files and log this income: [source], $[amount], [date], [category]."

Your agent will create the file structure and start tracking immediately.

---

Setup (5 Steps)

Step 1 — Create Finance Directory

Your agent creates a /finance/ folder in your workspace (or wherever you prefer):

finance/
  README.md           ← how to use these files
  income-log.md       ← all income entries
  expense-log.md      ← all expense entries
  monthly-summary.md  ← running monthly P&L (appended each month)
  finance-state.json  ← targets, YTD totals, running balances
  tax-estimates.md    ← quarterly tax tracking

Tell your agent: "Create the finance directory structure using the Financial Tracker skill."

Step 2 — Set Your Targets

Your agent will ask for:

• Monthly revenue target — your income goal per month (e.g., $5,000)
• Annual revenue target — your yearly income goal (e.g., $60,000)
• Expense budget — monthly spend ceiling (e.g., $500)
• Tax rate estimate — rough self-employment rate (e.g., 30% — adjust based on your situation)

These go into finance-state.json and are used for all progress calculations.

⚠️ Tax Disclaimer: This skill provides rough estimates only. It is not tax advice. Consult a qualified tax professional for your actual tax obligations.

Step 3 — Log Your First Income Entry

Tell your agent:

"Log income: [source name], $[amount], [date], [category]"

Example: "Log income: Gumroad digital sales, $320, March 6, digital-products"

Your agent appends to income-log.md in this format:

| 2026-03-06 | Gumroad digital sales | $320.00 | digital-products | — |

Step 4 — Log Expenses

Tell your agent:

"Log expense: [vendor], $[amount], [date], [purpose], [tax-deductible: yes/no]"

Example: "Log expense: Canva Pro, $15, March 1, design tools, yes"

Step 5 — Get Your First Snapshot

Tell your agent: "Give me a financial snapshot for this month."

Your agent generates a P&L summary, shows goal progress, and flags any concerns.

Usage Patterns

Log Income

"Log income: [source], $[amount], [date], [category]"

"Add revenue: Consulting call with client, $300, today, services"

Log Expense

"Log expense: [vendor], $[amount], [date], [purpose], tax-deductible"

"Record expense: Mailchimp, $13, March 1, email marketing, yes"

Monthly Snapshot

"Financial snapshot for [month]" or "How did March go financially?"

Agent generates:

## March 2026 P&L

Income:       $1,247.00
Expenses:     $  182.50
Net Income:   $1,064.50

Revenue Goal Progress: $1,247 / $5,000 (24.9%) ← behind pace
Expense vs Budget:     $182.50 / $500 (36.5%) ✅ on track
Tax Reserve:           ~$319 set aside (30% of $1,064 net)

⚠️ Flag: Revenue concentration — 73% from one source (services)

YTD Summary

"Year-to-date financial summary" or "How's 2026 going financially?"

Revenue Goal Check

"Am I on track to hit my revenue goal this month?"

Tax Estimate

"What should I be setting aside for quarterly taxes?"

Agent calculates rough self-employment tax based on YTD net income and your configured rate.

Expense Review

"What did I spend money on this month?" or "What are my recurring expenses?"

Income Breakdown

"Break down my income sources for this quarter"

---

Monthly P&L Format

Your agent appends a monthly summary to monthly-summary.md at the end of each month (or on demand):

## March 2026

**Income**
| Source | Amount |
|--------|--------|
| Digital products | $587.00 |
| Services | $660.00 |
| **Total Income** | **$1,247.00** |

**Expenses**
| Category | Amount |
|----------|--------|
| Tools/software | $68.00 |
| Platform fees | $78.50 |
| Education | $36.00 |
| **Total Expenses** | **$182.50** |

**Net Income:** $1,064.50
**vs. Monthly Target ($5,000):** 21.3% — below target
**Tax Reserve (30%):** ~$319

**Flags:**
- ⚠️ Revenue below target by $3,752
- ✅ Expenses within budget
- ⚠️ Income concentration: 53% from services (single-source risk)

---

---

Cash Flow Flags

Your agent automatically raises these warnings during any snapshot:

Flag	Trigger	Why It Matters
⚠️ Revenue Below Pace	< 50% of monthly target by mid-month	You may fall short — act now
⚠️ Income Concentration	1 source > 60% of income	Client/product loss = big problem
⚠️ Expense Spike	Month expenses > 120% of prior month	Something changed — review it
⚠️ No Income Logged	7+ days with zero entries	Activity may have stalled
🔴 Negative Month	Net income < $0	Expenses exceeded revenue
✅ Goal Hit	Revenue ≥ monthly target	Celebrate, then plan the next

---

Tax Estimate Tracking

Your agent maintains a rough quarterly tax ledger in tax-estimates.md:

# Tax Estimates

> ⚠️ Rough estimates only — not tax advice. Consult a professional.

## 2026

| Quarter | Net Income | Estimated Tax (30%) | Due Date | Status |
|---------|------------|---------------------|----------|--------|
| Q1 (Jan–Mar) | $0 | $0 | April 15 | — |
| Q2 (Apr–Jun) | — | — | June 15 | — |
| Q3 (Jul–Sep) | — | — | Sept 15 | — |
| Q4 (Oct–Dec) | — | — | Jan 15 | — |

Tell your agent: "Update my Q1 tax estimate" and it recalculates based on logged net income.

---

AGENTS.md Standing Instructions

Add this to your AGENTS.md so your agent always knows its financial role:

## Financial Tracking

I maintain a `finance/` directory with income and expense logs. When I mention revenue, sales, or spending:
- Log income entries to `finance/income-log.md`
- Log expense entries to `finance/expense-log.md`
- Update `finance/finance-state.json` YTD totals after each entry
- Never auto-send financial summaries externally
- Flag if monthly revenue is below 50% of target by mid-month
- Remind me at month-end to close the books and generate a P&L summary

---

Customization

Adjust Income Categories

In income-log.md, replace or add category labels to match your business model. No code changes needed — just use your own labels consistently.

Multiple Revenue Streams

If you have separate businesses or products, add a stream column:

| Date | Source | Amount | Category | Stream | Notes |
|------|--------|--------|----------|--------|-------|
| 2026-03-05 | Gumroad | $49 | digital | guide-sales | — |
| 2026-03-05 | Etsy | $12 | digital | cards | — |

Tell your agent: "Break down income by stream this month."

Currency

All entries default to USD. To use a different currency, tell your agent:

"Use [EUR/GBP/CAD/etc.] for all financial tracking."

It will note the currency in file headers.

Monthly Recurring Expenses

For recurring subscriptions, tell your agent:

"Add a recurring expense: [vendor], $[amount], [day of month], [purpose], [tax-deductible]"

Your agent will remind you to log it each month and flag if it goes missing.

Income Alerts

Set a target and ask your agent to alert you via heartbeat when you hit milestones:

## HEARTBEAT.md (finance section)
- Check finance/income-log.md — has monthly income crossed $1,000? $3,000? $5,000? 
  If a new milestone crossed, surface it in the briefing.
