spend-optimizer
Complete spend optimization: subscription auditing + credit card rewards maximization.
What This Does
- Subscription Audit - Find recurring charges, categorize (keep/cancel/investigate), calculate savings
- Card Optimization - Map charges to optimal credit cards based on reward categories
- Credit Optimization - Flag services you're paying for that should be FREE via card credits
- Interactive Reports - HTML dashboards with dispute tracking, notes, and actionable insights
Workflow
Step 1: Get Transaction CSVs
Ask user for bank/card CSV exports. Support multiple cards for full optimization.
Common export sources:
- Apple Card: Wallet → Card Balance → Export
- Amex: Account → Statements & Activity → Download
- Chase: Accounts → Download activity → CSV
- Mint/Copilot: Transactions → Export all
Important: Request exports from ALL cards for accurate optimization. Note the last 4 digits of each card number.
Step 2: Gather Card Information
Ask user about their credit cards:
What credit cards do you have? For each, I need:
- Last 4 digits (for matching to transactions)
- Card name (e.g., "Amex Gold", "Chase Sapphire")
- Annual fee (if known)
Check credit-cards.md for common card reward structures.
Step 3: Analyze Transactions
Read all CSVs and identify:
Recurring charges:
- Same merchant, similar amounts, monthly/annual frequency
- Flag subscription-like charges (streaming, SaaS, memberships)
- Note charge frequency and total annual cost
Card optimization opportunities:
- Which card each charge is currently on
- Which card it SHOULD be on for max rewards
- Calculate potential rewards gain from moving charges
Credit/perk opportunities:
- Check credit-cards.md Statement Credits section
- Flag any service the user is paying for that's covered by a card credit they have
- Examples:
- Paying for Disney+ on Chase → Should be on Amex Platinum (free $7/mo credit)
- Paying for Uber on random card → Should be on Amex Platinum ($15/mo) or Amex Gold ($10/mo)
- Paying for DoorDash → Should be on Chase Sapphire Reserve (free DashPass + $5/mo)
- Paying for Adobe → Should be on Amex Business Platinum ($150/yr credit)
- Paying for cell phone bill → Should be on Amex Business Platinum ($10/mo wireless credit)
Step 4: Categorize with User
For each subscription, ask user to set status:
- Keep - Intentional, continue paying
- Cancel - Stop immediately
- Investigate - Needs decision (unsure, contract trap)
- Dispute - Never got access, want refund
Ask in batches of 5-10 to avoid overwhelming. Include card optimization recommendation with each.
Step 5: Generate HTML Report
Use template.html to create interactive report:
Header section:
- Subscription count and total monthly spend
- Potential annual rewards with optimized card usage
- Savings from cancelled subscriptions
- Dispute count and value
Card legend:
- List all user's cards with color coding
- Show reward categories for each card
Subscription rows include:
- Service name and monthly amount
- Current card (color-coded badge)
- Optimal card with "OK" or "MOVE" indicator
- Status dropdown (Keep/Cancel/Investigate/Dispute)
- Notes field for user comments
- Frequency (monthly/annual/etc.)
Features:
- Auto-save to localStorage
- Export disputes button
- Privacy toggle (blur names)
- Collapsible sections
- Dark mode support
Step 6: Generate Card Optimization Plan
If significant optimization opportunities exist, create card-optimization.html:
- Card arsenal overview (all cards, fees, reward structures)
- Spend routing strategy table
- Action items for card migration
- Quick reference cheat sheet
- Monthly checklist
- ROI summary (fees vs rewards)
Step 7: Help Cancel & Dispute
When user is ready to act:
Cancellations:
- Check common-services.md for cancel URLs
- Use browser automation to navigate and cancel if requested
- Update HTML row status when done
Disputes:
- Export disputes from HTML report
- Provide guidance on disputing with card issuer
- Note: Most cards allow disputes within 60-120 days

Tips
For maximum value:
- Get CSVs from ALL cards (not just one)

- Track category cap progress quarterly
- Update card payment methods for "MOVE" items
- Set calendar reminders for annual subscriptions
Red flags to surface:
- Duplicate subscriptions (same service, multiple charges)
- Price increases - Compare same merchant across months (see Price Increase Detection below)
- Zombie charges (services no longer used)
- Trial conversions (free trial → paid)
- Annual charges - Flag yearly subscriptions with renewal estimates (see Annual Tracker below)
- Missed credits - Paying for something covered by a card credit (see below)
- Category cap warnings - Alert when approaching $150K limits (see Cap Tracker below)

Report format for missed credits:
When flagging a missed credit, show:
⚠️ MISSED CREDIT: You're paying $X.XX/mo for [Service] on [Current Card]
→ Move to [Credit Card] to get it FREE ($XX/yr savings)
Price Increase Detection
Compare the same merchant across multiple months to catch silent price increases.
How to detect:
- Group transactions by merchant name (normalize: lowercase, remove extra spaces)
- For recurring charges, compare amounts month-over-month
- Flag if current amount > previous amount
Report format:
⚠️ PRICE INCREASE: [Service] went from $X.XX to $Y.YY (+Z%)
First seen at new price: [Date]
Consider: Is this still worth it at the new price?
Common patterns:
- Streaming services: Often increase $1-2/mo annually
- SaaS tools: May increase 10-20% at renewal
- Annual subscriptions: Harder to notice since you only see once/year
Thresholds:
- Flag any increase > $1 or > 5%
- Highlight increases > 20% as significant
Annual Subscription Tracker
Annual charges are easy to forget. Flag them and estimate renewal dates.
How to detect:
- Look for charges that appear only once in 6-12 months of data
- Check if amount suggests annual billing ($100+ single charge vs $10 monthly)
- Look for merchant names containing: "annual", "yearly", or known annual services
Known annual services to watch for:
- Domain registrations (GoDaddy, Namecheap, Google Domains)
- Annual software licenses (Adobe, Microsoft 365)
- Memberships (Costco, Amazon Prime, warehouse clubs)
- Professional subscriptions (industry associations)
- Insurance premiums
- Accounting software (QuickBooks, FreshBooks)
Report format:
📅 ANNUAL SUBSCRIPTION: [Service] - $XXX/year
Last charged: [Date]
Estimated renewal: [Date + 1 year]
⏰ Set reminder for [2 weeks before renewal]
In HTML report:
- Add "Annual" badge to these subscriptions
- Show estimated renewal date
- Sort annual subscriptions by upcoming renewal date
Category Cap Tracker
Track spending against bonus category caps to maximize rewards.
Key caps to track:
| Card | Category | Cap | Multiplier After |
|---|
| Amex Business Gold | Each bonus category | $150,000/yr | 1x |
| Amex Blue Business Plus | All purchases | $50,000/yr | 1x |
| Chase Ink Preferred | Combined bonus categories | $150,000/yr | 1x |

| Chase Ink Cash | Gas/dining | $25,000/yr | 1% |
| BofA Customized Cash | Choice category | $50,000/yr | 1% |
How to track:
- Categorize each transaction by reward category
- Sum spending per category per card
- Calculate percentage of cap used
- Project when cap will be hit based on monthly average
Report format:
📊 CATEGORY CAP STATUS: [Card Name]
Advertising: $87,500 / $150,000 (58%) ████████░░░░
Software: $42,000 / $150,000 (28%) ████░░░░░░░░
Shipping: $12,000 / $150,000 (8%) █░░░░░░░░░░░
⚠️ At current pace, you'll hit Advertising cap in ~2.5 months
→ Consider moving overflow to Chase Ink Preferred (3x)
