Flosak is a lightweight receivables tracking system designed for very small businesses and solo operators. Instead of focusing on traditional invoicing and accounting workflows, Flosak centers around uncollected money as the core entity. The system allows users to: Record simple transactions (client, amount, reason, due date) Optionally convert transactions into invoices Track outstanding, overdue, and upcoming payments in a single dashboard Send and log payment reminder communications Mark payments as received with basic payment method notes Generate human-readable monthly summaries (collected, outstanding, overdue) Flosak intentionally avoids accounting terminology, bank integrations, and tax complexity to reduce cognitive load and increase daily usage. Target users include freelancers, workshops, clinics, and small B2B service providers with short payment cycles and minimal operational overhead.
