Company profile
researched Sep 2026Sumly offers bookkeeping software aimed exclusively at self-employed professionals, freelancers and solopreneurs. The product connects to a user's bank accounts and automatically sorts transactions into categories, flagging tax-deductible and partially deductible items (for example, meals at 50%) so that deductions are identified without manual receipt collection or spreadsheets. Alongside expense tracking and ongoing bookkeeping, the service calculates quarterly estimated tax payments, supports tax filing handled by a licensed tax professional, and offers business setup such as LLC formation, with human support available for questions.
The company positions the product against general small-business accounting tools that it characterizes as designed for firms with employees and an outside accountant, arguing those require lengthy setup and ongoing weekly admin. Sumly's stated alternative is quick bank connection, automatic categorization for user review, and read-only bank access through Plaid with encryption. Marketing materials cite roughly 50 hours a year saved and refunds in a $2,000-$18,000 range, and customer testimonials reference individual savings figures.
Founding story
Co-founders Maggi Heneghan and Maximo Librandi met at a pitch competition at Columbia University, where Librandi was completing a Master's in Engineering and Heneghan was at the Business School. Heneghan had worked in consulting and fintech and observed friends going independent and losing time to receipts and quarterly taxes; Librandi, a software engineer and former freelancer, had experienced the same administrative burden. They built Sumly as a simpler way for independent workers to track expenses, keep books and handle taxes.

Market position
Sumly positions itself as a niche alternative to general accounting tools such as QuickBooks, which its materials describe as built for businesses with employees and an accountant and as feeling like unpaid work for solo earners.
Sumly is scoped to self-employed earners rather than businesses with employees and accountants, emphasizing fast bank-connection onboarding and automatic categorization instead of manual setup, read-only Plaid access rather than broader bank credentials, and inclusion of licensed tax professionals for filing and questions within the subscription.
