Claude's Finance Agents

A set of Claude agents that track spending, model budgets, and watch your money for you.

These are Claude agent setups you can run today — in Claude.ai Projects, via the API, or inside your own tools. Each category below is a self-contained agent design: copy the prompt, paste it into a Claude Project system prompt or a conversation, and wire it to your data. No coding background required for the simpler ones. For the API-based agents, you'll need basic familiarity with calling Claude programmatically or a no-code tool like Make or Zapier.

Spending Tracker Agents

/categorize-transactions — paste a CSV of bank or card transactions and Claude assigns each line a category (food, software, ads, travel, etc.) and flags anything that looks wrong
/weekly-spend-summary — give Claude your week's transactions and it returns a plain-English breakdown of where money went, what changed vs. the prior week, and what to watch
/find-duplicates — run your subscription list through this agent and it surfaces duplicate charges, overlapping tools doing the same job, and charges you probably forgot about
/tag-business-vs-personal — paste mixed expenses and Claude separates them by likely deductibility, flagging ambiguous items for your review

Budget Modeling Agents

/build-zero-based-budget — give Claude your income and fixed costs, and it drafts a zero-based budget that allocates every dollar with justification for each line
/scenario-model — describe a business decision (hire a contractor, buy a tool, run an ad campaign) and Claude models the budget impact across three scenarios: conservative, base, and optimistic
/runway-calculator — input your current cash balance and monthly burn rate and Claude tells you your runway, the break-even threshold you need to hit, and what levers change the number most
/reforecast — give Claude your original budget and your actuals through the current month, and it rewrites the rest of the year's forecast based on the delta

Cash Flow Agents

/map-cash-flow — describe your revenue timing and fixed obligations and Claude builds a 13-week cash flow map showing which weeks are tight and where you have slack
/late-payment-alert — feed Claude your invoices and due dates; it tells you which clients are late, calculates the impact on your next 30 days, and drafts follow-up messages
/gap-finder — Claude identifies gaps between when you get paid and when bills are due, then suggests how to restructure payment terms to reduce the pinch

Subscription and Vendor Audit Agents

/subscription-audit — list every recurring charge; Claude evaluates each one for ROI signal, identifies redundancy, and ranks them by cut-first priority
/vendor-compare — describe what a tool does and what you pay; Claude researches the category and returns 3–5 alternatives with estimated cost differences
/contract-flag — paste a vendor contract or terms of service and Claude highlights auto-renewal clauses, price escalation terms, and exit penalties

Tax Prep Support Agents

/deduction-checklist — describe your business type and Claude returns a categorized list of common deductions for your situation, with questions to ask your accountant
/quarterly-estimate-prep — input your revenue and expenses by quarter and Claude helps you organize the numbers in the format your CPA or tax software expects
/expense-memo-writer — paste a transaction and Claude writes a short business-purpose memo you can attach to the record for audit-readiness

Claude is not a licensed financial advisor or CPA. Use these agents to organize, model, and draft — then run the outputs by a qualified professional before making major financial decisions.

Revenue Analysis Agents

/revenue-breakdown — paste your sales data and Claude segments it by product, channel, or customer type and tells you where revenue is actually coming from
/ltv-estimator — give Claude your average purchase value, purchase frequency, and churn rate, and it calculates customer lifetime value and what acquiring a customer is worth
/pricing-pressure-test — describe your offer and current price; Claude stress-tests the pricing against your cost structure, market positioning, and common objections
/churn-impact-model — input your current MRR and churn rate and Claude models what reducing churn by 1%, 2%, or 5% does to your revenue over 12 months

Invoice and Accounts Receivable Agents

/invoice-writer — give Claude the job details, deliverables, and amount and it writes a clean, professional invoice in plain text or markdown you can paste into your invoicing tool
/ar-aging-summary — paste your open invoices with due dates and Claude buckets them by age (current, 30, 60, 90+ days) and flags the highest-risk accounts
/collections-sequence — Claude writes a 3-message follow-up sequence for an overdue invoice: a gentle reminder, a firmer notice, and a final demand — all in your tone

Ad Spend and ROI Agents

/ad-roi-calculator — input your ad spend, clicks, conversion rate, and offer price; Claude calculates ROAS, cost per acquisition, and tells you whether the math works
/budget-allocation-model — give Claude your total ad budget and your channel options; it recommends an allocation based on your stated goals and the relative cost of each channel
/spend-vs-return-audit — paste your last 90 days of ad spend alongside revenue by channel and Claude tells you which channels are pulling weight and which are eating budget

Financial Decision Support Agents

/hire-vs-tool — describe a task you're considering automating or delegating; Claude models the cost of hiring a person vs. buying software vs. using AI, with break-even timelines
/buy-vs-build — describe a system you need; Claude lays out the build cost, maintenance overhead, and opportunity cost vs. buying an existing solution
/offer-profitability-check — give Claude your offer price, delivery costs, and time investment; it calculates your actual margin and flags where profit is leaking

Starter Prompt Templates
