Frequently Asked Questions
How does client profitability tracking work?
Assign income (invoices) and expenses (contractor costs, tools, travel) to specific clients. AccountsOS calculates profit per client automatically. See which clients are gold and which are costing you money.
Can I track retainers separately from projects?
Yes. Set up retainer agreements with recurring income. Project work is tracked separately. See how much of your revenue is recurring (stable) vs project-based (variable).
How do I handle contractor payments?
Log contractor invoices and assign them to specific clients or projects. See true project profitability including outsourced work. Manage contacts so contractor records are always accessible.
What about clients who pay late?
AccountsOS tracks invoice status and shows you outstanding amounts per client. See who owes you money and how overdue they are. Send reminder emails directly from the platform.
