Executive Summary

Solo founders and solopreneurs—around 20 million in key markets—spend disproportionate time on manual invoicing, chasing payments, and expense categorization, which siphons hours away from product development and customer work and tightens cash flow for one-person businesses. Even small delays in collections or repeated manual edits meaningfully reduce runway and growth capacity for solo operators. You could build a lightweight, mobile-first AI billing assistant that auto-extracts billable items from contracts, time logs, emails and receipts, generates compliant invoices with embedded payment links, automates polite follow-ups and reconciliation, and routes payouts via integrated payment rails. Design for under-five-minute onboarding and a $300 ACV core plan with optional faster-payout or bookkeeping export add-ons. The addressable market is compelling—roughly $6.0B (20M solopreneurs × $300 ACV) with a high market score (90/100) and strong tailwinds from the rise of independent work, payments-first expectations, and AI-enabled automation. These trends make solo founders both able and willing to pay for reliable tools that meaningfully cut admin time and improve DSO. You can stand out by optimizing end-to-end solo workflows (tax-ready templates, one-click reconciliations), investing in best-in-class LLM extraction to minimize manual corrections, and bundling fast, transparent payouts to beat general-purpose invoicing tools. The honest challenges are medium competition, proving payment/security reliability, and acquiring users cost-effectively—early partnerships with freelancer marketplaces or tax/prep services will be critical to de-risk go-to-market.
