Stop chasing invoices by hand
The most common reason small-business invoices are paid late is simple: nobody reminded the customer. Aqeris flags an invoice as overdue the day after its due date, emails the customer a polite reminder, and notifies the owner.
Reminders are throttled (every three days by default, capped at five) so customers are nudged, not nagged. Owners see outstanding balances on the dashboard and in their notifications until the invoice is settled.
