Ledger & Invoice

A simplified invoicing and bookkeeping SaaS platform built specifically for solopreneurs and freelancers to streamline billing, expense tracking, and tax preparation without complex accounting knowledge.

Executive summary

We are building Ledger & Invoice, a lean SaaS product that combines invoicing and basic bookkeeping for independent professionals. Our target market is the 27 million US freelancers and solopreneurs who currently juggle spreadsheets, PayPal invoices, or costly enterprise accounting software. We will launch with a freemium model, offering core invoicing free and charging for bookkeeping automation and tax reports, reaching profitability within 18 months.
