This is not only positioning copy anymore
The product now has the core workflow pieces required to support the anti-Friday story in the app itself.
Payments and open amounts are tracked
Invoices now carry paid and open balances, and manual payment recording supports partial receipts instead of all-or-nothing status changes.
Reminder flow is in the product
Businesses can configure reminder timing, send reminders from invoice and cashflow views, and run a daily reminder job with dry-run support.
Cashflow data is usable in app and API
There is a dedicated cashflow view for operators plus authenticated and public forecast endpoints for dashboards, automation, and external systems.
Automate your billing with the QuoteCash API
Automate invoices and e-invoice PDFs directly from your workflows.
Invoices after Project Completion
Trigger an invoice via API as soon as a project is marked complete in your tool.
