Generate invoices from templates

To generate invoices from templates, you can follow these steps depending on your preferred platform (manual, Excel, Google Docs, or programmatically):

1. Using Microsoft Word or Google Docs Templates

Steps:

• Open a pre-designed invoice template (search “Invoice Template” in Word/Docs).

• Replace placeholder fields with:

  • Invoice Number

  • Date

  • Client Information

  • Service/Product Details

  • Rates, Quantity, Subtotals

  • Total Amount

  • Payment Terms

• Save as PDF and send.

2. Using Excel or Google Sheets Templates

Advantages: Automatic calculations, reusable.

Steps:

• Download or open an invoice template (from Microsoft or Google template galleries).

• Edit the following:

  • Company name/logo/contact

  • Client details

  • Invoice number and date (can auto-increment)

  • Itemized services/products with pricing formulas

  • Tax/VAT if applicable

  • Total and payment instructions

• Export as PDF or share via link/email.

3. Using Online Invoice Generators

Popular tools:

• Invoice Generator (invoice-generator.com)

• Zoho Invoice

• PayPal Invoicing

• Wave Accounting

Steps:

• Select a template.

• Enter business and client details.

• Add services/products and cost.

• Preview and download/send directly.

4. Programmatic Invoice Generation (for developers)

Using Python (with Jinja2 + PDFKit or WeasyPrint):

python
CopyEdit
from jinja2 import Environment, FileSystemLoader
import pdfkit

env = Environment(loader=FileSystemLoader('.'))
template = env.get_template("invoice_template.html")

invoice_data = {
    "invoice_number": "INV-1001",
    "date": "2025-05-18",
    "client": {"name": "John Doe", "address": "123 Main St"},
    "items": [
        {"description": "Web Design", "quantity": 1, "rate": 500},
        {"description": "Hosting", "quantity": 12, "rate": 10},
    ],
    "total": 620
}

html_out = template.render(invoice_data)
pdfkit.from_string(html_out, "invoice_output.pdf")

Note: Ensure wkhtmltopdf is installed if using pdfkit.

5. Automating from a CRM or Billing System
