Invoice & Receipt Generator

The problem

Freelancers and solopreneurs often waste time wrestling with spreadsheets or paying for expensive accounting software just to send a basic bill. Manual formatting leads to math errors, missed payment terms, and unprofessional-looking documents that delay getting paid.

Built with beginners in mind — enter your service details and client information, and this skill produces professional invoices and receipts instantly. No accounting or bookkeeping experience required. Experienced business owners save time too: consistent formatting and automatic calculations on every invoice means fewer errors and faster payments.

What it does

• Generates structured, professional invoices for hourly, flat-fee, or retainer-based work.
• Calculates subtotals, taxes, discounts, and deposits automatically to ensure mathematical accuracy.
• Produces payment receipts to confirm received funds and close out client accounts.
• Provides companion email templates tailored to the specific invoice to streamline client communication.

Why this beats prompting it yourself

General AI prompts often forget critical business details like late fee policies, Net terms, or clear subtotal breakdowns. This skill uses a standardized, clean Markdown schema that is ready to paste into Notion, Google Docs, or emails without broken formatting or logical gaps.

Use cases

• Creating a Net-30 invoice for a corporate client after completing a project.
• Billing a client for a mix of hourly services and flat-rate expenses like research or travel.
• Generating an official payment receipt once a bank transfer is confirmed.
• Calculating total due for services that include a specific sales tax percentage and a prior deposit.
