Generate beautiful invoices in seconds. No dependencies, no subscriptions, no cloud required. Clean Python code. --- **Professional invoice generation for freelancers and small businesses.** Generate beautiful, professional invoices in seconds. No dependencies, no subscriptions, no cloud required. Just clean Python code that works. Created by **Shadow Rose** • quality-verified • MIT License --- ## What It Does Invoice Forge helps you: - **Generate professional invoices** with clean, print-ready HTML templates - **Manage clients** with a simple database - **Track payments** and see what's overdue at a glance - **Calculate taxes and discounts** automatically - **Create recurring invoices** from templates (monthly retainers, subscriptions) - **Run reports** on revenue, outstanding balances, and client activity Perfect for freelancers, consultants, indie creators, and small businesses who need invoicing that just works. --- ## Quick Start ### 1. Set Up Your Configuration Copy the example config and customize it: ```bash cp config_example.json config.json ``` Edit `config.json` with your business details: ```python BUSINESS_NAME = "Acme Consulting" BUSINESS_EMAIL = "[REDACTED_SECRET]" CURRENCY_SYMBOL = "$" DEFAULT_PAYMENT_TERMS = 30 # Net 30 TAX_RATES = {"sales_tax": 0.08} # 8% sales tax ``` ### 2. Add a Client ```bash python invoice_clients.py add client001 "John Doe" "[REDACTED_SECRET]" "123 Main St, City" "+1-555-0100" ``` ### 3. Create an Invoice ```bash python invoice_forge.py create client001 \ --item "Web Design Services" 1 2500.00 \ --item "Hosting Setup" 1 500.00 \ --terms 30 ``` This creates an invoice, saves it as HTML in the `output/` folder, and records it in your ledger. ### 4. View Your Invoices ```bash # List all invoices python invoice_forge.py list # See summary stats python invoice_report.py summary # Check for overdue invoices python invoice_report.py overdue ``` --- ## Features ### Client Management Store client details once, reuse forever: ```bash # Add a client python invoice_clients.py add acme "Acme Corp" "[REDACTED_SECRET]" # List all clients python invoice_clients.py list # Search clients python invoice_clients.py list "acme" # Update client info python invoice_clients.py update acme phone="+1-555-1234" # Get client details python invoice_clients.py get acme ``` ### Invoice Generation Create invoices with multiple line items, taxes, and discounts: ```bash # Basic invoice python invoice_forge.py create client001 \ --item "Consulting" 10 150.00 \ --item "Expenses" 1 250.00 # With discount python invoice_forge.py create client001 \ --item "Web Development" 40 125.00 \ --discount-percent 10 # With custom terms python invoice_forge.py create client001 \ --item "Design Work" 1 5000.00 \ --terms 15 \ --notes "Thank you for your business!" # Custom invoice date python invoice_forge.py create client001 \ --item "Monthly Retainer" 1 3000.00 \ --date 2024-01-01 ``` ### Output Formats Generate invoices in multiple formats: ```bash # HTML (default - professional, print-ready) python invoice_forge.py create client001 --item "Service" 1 1000 --format html # Markdown (for version control, notes) python invoice_forge.py create client001 --item "Service" 1 1000 --format markdown # Plain Text (for email, terminal display) python invoice_forge.py create client001 --item "Service" 1 1000 --format text ``` ### Payment Tracking Update invoice status as payments come in: ```bash # Mark as paid python invoice_forge.py status INV-0001 paid # Mark as cancelled python invoice_forge.py status INV-0002 cancelled # List by status python invoice_forge.py list --status pending python invoice_forge.py list --status paid ``` ### Recurring Templates Set up templates for regular invoices: Edit `config.json`: ```python RECURRING_TEMPLATES = { "monthly_retainer": { "items": [ {"description": "Monthly Retainer", "quantity": 1, "rate": 5000.00} ], "payment_terms": 15, "notes": "Monthly retainer for ongoing services.", }, } ``` Then use it: ```bash python invoice_forge.py template monthly_retainer client001 ``` ### Reports & Analytics Get insights into your business: ```bash # Overall summary python invoice_report.py summary # Client-specific summary python invoice_report.py client client001 # Overdue invoices python invoice_report.py overdue # Revenue by month python invoice_report.py revenue --period month # Top clients by revenue python invoice_report.py top --limit 10 # Aging report (who owes what for how long) python invoice_report.py aging ``` --- ## Use Cases ### Freelance Consultants Track client hours, generate invoices weekly or monthly, monitor who's paid and who hasn't. ```bash python invoice_forge.py create client001 \ --item "Strategy Consulting - Week of Jan 15" 20 200.00 \ --terms 15 ``` ### Digital Product Sellers Invoice for one-time purchases, custom work, or licensing fees. ```bash python invoice_forge.py create client002 \ --item "Premium License - VideoEdit Pro" 1 499.00 \ --item "Priority Support (1 year)" 1 99.00 ``` ### Small Agencies Manage multiple clients, track monthly retainers, generate reports for accounting. ```bash # Set up recurring template in config.json python invoice_forge.py template monthly_retainer agency_client_001 python invoice_forge.py template monthly_retainer agency_client_002 # Review outstanding balances python invoice_report.py aging ``` ### Service Providers Track project-based work with multiple line items and milestones. ```bash python invoice_forge.py create startup_co \ --item "Website Design - Phase 1" 1 3500.00 \ --item "Logo Design" 1 800.00 \ --item "Brand Guidelines Document" 1 500.00 \ --discount-percent 5 \ --notes "Milestone 1 of 3 - Design Phase" ``` --- ## Configuration Reference ### Business Profile ```python BUSINESS_NAME = "Your Business Name" BUSINESS_ADDRESS = """123 Main Street Suite 456 City, State 12345""" BUSINESS_EMAIL = "[REDACTED_SECRET]" BUSINESS_PHONE = "+1 (555) 123-4567" BUSINESS_LOGO = None # Path to logo image (optional) PAYMENT_DETAILS = """Bank Transfer: ... PayPal: [REDACTED_SECRET]""" ``` ### Invoice Settings ```python INVOICE_PREFIX = "INV-" # Invoice number prefix INVOICE_START = 1 # Starting number INVOICE_PADDING = 4 # Zero-pad to 4 digits (INV-0001) DEFAULT_PAYMENT_TERMS = 30 # Net 30 ``` ### Currency ```python CURRENCY_SYMBOL = "$" CURRENCY_CODE = "USD" ``` ### Taxes ```python TAX_RATES = { "sales_tax": 0.08, # 8% "vat": 0.20, # 20% } DEFAULT_TAX_TYPE = "sales_tax" TAX_LABELS = { "sales_tax": "Sales Tax", "vat": "VAT", } ``` ### Recurring Templates ```python RECURRING_TEMPLATES = { "monthly_retainer": { "description": "Monthly Retainer", "items": [{"description": "...", "quantity": 1, "rate": 5000.00}], "payment_terms": 15, "notes": "...", }, } ``` --- ## File Structure ``` invoice-forge/ ├── config_example.json # Configuration template ├── config.json # Your config (create from example) ├── invoice_forge.py # Main invoice engine ├── invoice_clients.py # Client management ├── invoice_report.py # Reports and analytics ├── invoice_template.py # HTML/Markdown/Text rendering ├── data/ │ ├── clients.jsonl # Client database │ └── invoices.jsonl # Invoice ledger └── output/ ├── INV-0001.html # Generated invoices ├── INV-0002.html └── ... ``` All data is stored as **JSONL** (JSON Lines) for: - **Human readability** - easy to grep, diff, and version control - **Append-only safety** - no risk of corruption - **Easy backup** - just copy the files --- ## Data Format ### Clients (data/clients.jsonl) ```json {"client_id": "client001", "name": "John Doe", "email": "[REDACTED_SECRET]", "address": "...", "phone": "...", "created_at": "...", "updated_at": "..."} ``` ### Invoices (data/invoices.jsonl) ```json {"invoice_number": "INV-0001", "invoice_date": "2024-01-15", "due_date": "2024-02-14", "client": {...}, "items": [...], "subtotal": 3000.00, "tax_amount": 240.00, "total": 3240.00, "status": "pending", ...} ``` --- ## Tips & Best Practices ### Version Control Your Invoices Keep your invoices under version control (git) for: - Full audit trail - Easy rollback if something breaks - Backup and recovery ```bash git init git add data/ output/ git commit -m "January invoices" ``` ### Backup Regularly The `data/` folder contains your entire business ledger. Back it up! ```bash # Simple backup cp -r data/ data-backup-$(date +%Y%m%d) # Or use git git add data/ git commit -m "Backup $(date)" ``` ### Use Recurring Templates If you bill the same thing regularly (monthly retainers, subscriptions), set up templates in `config.json`. Saves time and ensures consistency. ### Check for Overdue Invoices Weekly ```bash python invoice_report.py overdue ``` Set a reminder to run this every Monday morning. Follow up promptly. ### Generate Tax Reports Revenue by month helps with quarterly/annual tax filing: ```bash python invoice_report.py revenue --period month ``` ### Print-to-PDF for Clients The HTML invoices are print-ready. Open in browser, print to PDF, send to clients. --- ## Python API You can also use Invoice Forge as a library: ```python from invoice_forge import InvoiceForge # Initialize forge = InvoiceForge() # Create invoice invoice = forge.create_invoice( client_id="client001", items=[ {"description": "Web Design", "quantity": 1, "rate": 2500.00}, {"description": "Hosting Setup", "quantity": 1, "rate": 500.00}, ], discount={"type": "percent", "value": 10}, notes="Thank you for your business!", ) # Render as HTML html = forge.render_invoice(invoice, format="html") # Save to file filepath = forge.save_rendered_invoice(invoice, format="html") print(f"Invoice saved to: {filepath}") ``` Client management: ```python from invoice_clients import ClientManager # Initialize clients = ClientManager() # Add client client = clients.add_client( client_id="client001", name="John Doe", email="[REDACTED_SECRET]", address="123 Main St", phone="+1-555-0100", ) # Get client client = clients.get_client("client001") # List all clients all_clients = clients.list_clients() # Search clients results = clients.list_clients(search="john") ``` Reports: ```python from invoice_report import InvoiceReporter # Initialize reporter = InvoiceReporter() # Overall summary summary = reporter.get_overall_summary() print(f"Total invoiced: ${summary['total_invoiced']:,.2f}") # Overdue invoices overdue = reporter.get_overdue_invoices() print(f"{len(overdue)} invoice(s) overdue") # Revenue by month revenue = reporter.get_revenue_by_period("month") for month, amount in revenue.items(): print(f"{month}: ${amount:,.2f}") ``` --- ## Requirements - **Python 3.7+** (uses standard library only) - **No external dependencies** - works out of the box --- ## Installation ```bash # Clone or download git clone <your-repo-url> invoice-forge cd invoice-forge # Set up config cp config_example.json config.json # Edit config.json with your business details # Start invoicing! python invoice_clients.py add client001 "John Doe" "[REDACTED_SECRET]" python invoice_forge.py create client001 --item "Service" 1 1000.00 ``` --- ## FAQ **Q: Where is my data stored?** A: All data is in the `data/` folder as JSONL files. Human-readable, version-control friendly. **Q: Can I customize the invoice template?** A: Yes! Edit `invoice_template.py` to change the HTML/CSS. The template is clean and well-commented. **Q: How do I handle multiple tax rates?** A: Define them in `config.json` under `TAX_RATES`, then specify `--tax <type>` when creating invoices. **Q: Can I add a logo?** A: Yes! Set `BUSINESS_LOGO = "logo.png"` in `config.json`. The logo will be embedded in HTML invoices. **Q: How do I email invoices?** A: Invoice Forge generates the invoice files; emailing is separate. Use your email client or a script to send the HTML files as attachments. **Q: Can I export to PDF directly?** A: The HTML template is print-ready. Open in browser, print to PDF. For automation, use a tool like `wkhtmltopdf` or headless Chrome. **Q: What about recurring subscriptions?** A: Set up templates in `config.json`, then use `python invoice_forge.py template <name> <client>` to generate them quickly. **Q: How do I migrate to a different system later?** A: Data is stored as JSONL (one JSON object per line). Easy to parse and import into any other system. --- ## Support This is open-source software provided as-is under the MIT License.
