Billing Trigger Density

Billing Trigger Density is the count of distinct events in a client engagement that can fire an invoice without a human deciding to send one. Agencies usually bill on a monthly retainer date, which means every approval lag, scope change, or milestone slip pushes revenue into the next cycle. Raising trigger density means wiring invoices to events that already happen: a signed statement of work, a completed sprint, a deposit at booking, a threshold of tracked hours. Hardbook collapses calendar hold, contract signature, and deposit into one client link, so the invoice fires at commitment rather than after it. Harvest converts tracked hours and expenses into invoices as work is logged, and Agicap connects bank and accounting data to forecast cash 13 weeks out. The framework matters because DSO is set by how many billing moments exist, not by how aggressively you chase payment.
