Personal Finance & Shared-Expense SaaS

Multi-tenant architecture4 split methodsDurable server-side rate limits

The brief

XplitX is a live personal-finance and shared-expense SaaS built as a true multi-tenant platform: accounts with member invites, account-scoped data isolation enforced at the security-rules layer, and a staff admin console operating beside the product. It covers the full money workflow — wallets and net worth, income and cash flow, custom categories, a budget grid, savings goals, a debt planner, CSV import, and receipt photo capture — plus the social layer: exact, percentage, share-based, and itemized expense splits with multi-currency settle-up. An AI proxy meters usage against plan credits, and durable server-side rate limits protect the platform under load.
