Finance & invoicing platform
We replaced 47 spreadsheet tabs with one finance app.
A services business ran its entire finances out of two monstrous workbooks — a profit-and-loss file and a client-invoice file, 47 tabs between them. Every month-end was copy-paste across tabs, manual reconciliation, and hoping a formula had not silently broken. Per-client statements and recurring invoices were all done by hand.
One multi-tenant web app behind single sign-on: cycle-aware P&L, organizations and memberships, and a real invoicing system — issued and recurring invoices, project line items, multi-currency, bulk drafting. Transactions import in, clean statements come out, and every figure is traceable instead of buried in a cell reference.
