How to Use

Basic Usage

Navigate to your messy invoice folder:

code

cd ~/Desktop/receipts-to-sort

Then ask Claude Code:

code

Organize these invoices for taxes

Or more specifically:

code

Read all invoices in this folder, rename them to 
"YYYY-MM-DD Vendor - Invoice - Product.pdf" format, 
and organize them by vendor

Advanced Organization

code

Organize these invoices:
1. Extract date, vendor, and description from each file
2. Rename to standard format
3. Sort into folders by expense category (Software, Office, Travel, etc.)
4. Create a CSV spreadsheet with all invoice details for my accountant

Instructions

When a user requests invoice organization:

•
Scan the Folder

Identify all invoice files:
bash
```
# Find all invoice-related files
find . -type f \( -name "*.pdf" -o -name "*.jpg" -o -name "*.png" \) -print
```
Report findings:
- •Total number of files
- •File types
- •Date range (if discernible from names)
- •Current organization (or lack thereof)
•
Extract Information from Each File

For each invoice, extract:

From PDF invoices:
- •Use text extraction to read invoice content
- •
  Look for common patterns:
  - •"Invoice Date:", "Date:", "Issued:"
  - •"Invoice #:", "Invoice Number:"
  - •Company name (usually at top)
  - •"Amount Due:", "Total:", "Amount:"
  - •"Description:", "Service:", "Product:"
From image receipts:
- •Read visible text from images
- •Identify vendor name (often at top)
- •Look for date (common formats)
- •Find total amount
Fallback for unclear files:
- •Use filename clues
- •Check file creation/modification date
- •Flag for manual review if critical info missing

•

Determine Organization Strategy

Ask user preference if not specified:

markdown

I found [X] invoices from [date range].

How would you like them organized?

1. **By Vendor** (Adobe/, Amazon/, Stripe/, etc.)
2. **By Category** (Software/, Office Supplies/, Travel/, etc.)
3. **By Date** (2024/Q1/, 2024/Q2/, etc.)
4. **By Tax Category** (Deductible/, Personal/, etc.)
5. **Custom** (describe your structure)

Or I can use a default structure: Year/Category/Vendor

•
Create Standardized Filename

For each invoice, create a filename following this pattern:
code
```
YYYY-MM-DD Vendor - Invoice - Description.ext
```
Examples:
- •2024-03-15 Adobe - Invoice - Creative Cloud.pdf
- •2024-01-10 Amazon - Receipt - Office Supplies.pdf
- •2023-12-01 Stripe - Invoice - Monthly Payment Processing.pdf
Filename Best Practices:
- •Remove special characters except hyphens
- •Capitalize vendor names properly
- •Keep descriptions concise but meaningful
- •Use consistent date format (YYYY-MM-DD) for sorting
- •Preserve original file extension

•

Execute Organization

Before moving files, show the plan:

markdown

# Organization Plan

## Proposed Structure

Invoices/ ├── 2023/ │ ├── Software/ │ │ ├── Adobe/ │ │ └── Microsoft/ │ ├── Services/ │ └── Office/ └── 2024/ ├── Software/ ├── Services/ └── Office/

code


## Sample Changes

Before: `invoice_adobe_march.pdf`
After: `2024-03-15 Adobe - Invoice - Creative Cloud.pdf`
Location: `Invoices/2024/Software/Adobe/`

Before: `IMG_2847.jpg`
After: `2024-02-10 Staples - Receipt - Office Supplies.jpg`
Location: `Invoices/2024/Office/Staples/`

Process [X] files? (yes/no)

After approval:

bash

# Create folder structure
mkdir -p "Invoices/2024/Software/Adobe"

# Copy (don't move) to preserve originals
cp "original.pdf" "Invoices/2024/Software/Adobe/2024-03-15 Adobe - Invoice - Creative Cloud.pdf"

# Or move if user prefers
mv "original.pdf" "new/path/standardized-name.pdf"

•

Generate Summary Report

Create a CSV file with all invoice details:

csv

Date,Vendor,Invoice Number,Description,Amount,Category,File Path
2024-03-15,Adobe,INV-12345,Creative Cloud,52.99,Software,Invoices/2024/Software/Adobe/2024-03-15 Adobe - Invoice - Creative Cloud.pdf
2024-03-10,Amazon,123-4567890-1234567,Office Supplies,127.45,Office,Invoices/2024/Office/Amazon/2024-03-10 Amazon - Receipt - Office Supplies.pdf
...

This CSV is useful for:

•Importing into accounting software
•Sharing with accountants
•Expense tracking and reporting
•Tax preparation

•

Provide Completion Summary

markdown

# Organization Complete! 📊

## Summary
- **Processed**: [X] invoices

Example 1: Tax Preparation (From Martin Merschroth)

User: "I have a messy folder of invoices for taxes. Sort them and rename properly."

Process:

•Scans folder: finds 147 PDFs and images
•
Reads each invoice to extract:
- •Date
- •Vendor name
- •Invoice number
- •Product/service description
•Renames all files: YYYY-MM-DD Vendor - Invoice - Product.pdf
•Organizes into: 2024/Software/, 2024/Travel/, etc.
•Creates invoice-summary.csv for accountant
•Result: Tax-ready organized invoices in minutes

Example 2: Monthly Expense Reconciliation

Output: Creates structure:

code

Invoices/
├── 2022/
│   ├── Adobe/
│   ├── Amazon/
│   └── ...
├── 2023/
│   ├── Adobe/
│   ├── Amazon/
│   └── ...
└── 2024/
    ├── Adobe/
    ├── Amazon/
    └── ...

Each file properly renamed with date and description.

Example 4: Email Downloads Cleanup

User: "I download invoices from Gmail. They're all named 'invoice.pdf', 'invoice(1).pdf', etc. Fix this mess."

Output:

markdown

Found 89 files all named "invoice*.pdf"

Reading each file to extract real information...

Renamed examples:
- invoice.pdf → 2024-03-15 Shopify - Invoice - Monthly Subscription.pdf
- invoice(1).pdf → 2024-03-14 Google - Invoice - Workspace.pdf

Common Organization Patterns

By Vendor (Simple)

code

Invoices/
├── Adobe/
├── Amazon/
├── Google/
└── Microsoft/

By Year and Category (Tax-Friendly)

code

Invoices/
├── 2023/
│   ├── Software/
│   ├── Hardware/
│   ├── Services/
│   └── Travel/
└── 2024/
    └── ...

│   ├── Q1/
│   │   ├── Software/
│   │   ├── Office/
│   │   └── Travel/
│   └── Q2/
│       └── ...

code

Invoices/
├── Deductible/
│   ├── Software/
│   ├── Office/
│   └── Professional-Services/
├── Partially-Deductible/
│   └── Meals-Travel/
└── Personal/

Automation Setup

For ongoing organization:

code

Create a script that watches my ~/Downloads/invoices folder 
and auto-organizes any new invoice files using our standard 
naming and folder structure.

This creates a persistent solution that organizes invoices as they arrive.

Pro Tips

•Scan emails to PDF: Use Preview or similar to save email invoices as PDFs first
•Consistent downloads: Save all invoices to one folder for batch processing
•Monthly routine: Organize invoices monthly, not annually
•Backup originals: Keep original files before reorganizing
•Include amounts in CSV: Useful for budget tracking
•Tag by deductibility: Note which expenses are tax-deductible
•Keep receipts 7 years: Standard audit period

Handling Special Cases

Missing Information

If date/vendor can't be extracted:

•Flag file for manual review
•Use file modification date as fallback
•Create "Needs-Review/" folder

Duplicate Invoices

If same invoice appears multiple times:

•Compare file hashes
•Keep highest quality version
•Note duplicates in summary

Multi-Page Invoices

For invoices split across files:

•Merge PDFs if needed
•Use consistent naming for parts
•Note in CSV if invoice is split

Non-Standard Formats

For unusual receipt formats:

•Extract what's possible
•Standardize what you can
•Flag for review if critical info missing

Related Use Cases

•Creating expense reports for reimbursement
•Organizing bank statements
•Managing vendor contracts
•Archiving old financial records
•Preparing for audits
•Tracking subscription costs over time
