SideStacks is the finance app built for the way you actually earn — multiple income streams, no spreadsheets, total clarity.
Free to start · No credit card required
Record income and expenses per stack, add notes, filter by category or date. Every dollar accounted for — without the spreadsheet.
Profit trends, income vs expenses, margin breakdown — all automatic. See your best month, spot patterns, and make better decisions.
Create a professional invoice in seconds, assign it to a stack, and track paid, pending, and overdue — all from one screen. No more chasing clients in your notes app.
Whether you've got one hustle or five, SideStacks keeps the numbers clear so you can stay focused on the work.

Record income and expenses as they happen. Categorise, add notes, attach invoices. Everything stays in one place.
Your dashboard shows exactly how each hustle is performing. Adjust, focus, and hit your goals faster.
