Expense Splitting for Small Teams

Our Common Ledger

Getting text messages at PM about who bought the toilet paper or the shared office coffee beans is a subtle, grinding kind of misery. Our Common Ledger is built for roommates, micro-agencies, and co-working groups who are sick of manual spreadsheets and awkward payment requests that sit unpaid for weeks. Instead of a complex enterprise suite or a chaotic group chat, this simple expense splitting app business functions as a lightweight team expense tracker app that connects directly to shared accounts or scans receipts to auto-split costs based on custom rules. You make money through a flat, low monthly subscription for team workspaces, alongside a tiny convenience fee for users who want to settle up instantly using direct bank transfers. Most legacy tools in this space have bloated their interfaces with annoying ads and aggressive paywalls, leaving a massive gap for a clean, privacy-first shared expense tool startup. To land your first ten groups, you need to go physical and hyper-local pitch to independent co-working managers, post on student housing boards, and sponsor local maker spaces with a dead-simple onboarding QR code. Your daily operation is less about complex software development and more about maintaining secure banking connections and fighting payment fraud. The growth ceiling is real; because users only think about splitting bills occasionally, you will eventually hit a wall where customer acquisition costs outpace user lifetime value unless you rely heavily on organic, viral invite loops.
