Service Delivery and Cash Operations Workbook

Connect accepted project work with available delivery hours, client obligations, billing assumptions and the dates cash can actually arrive.

By PriceAndProfit Editorial Updated Oct 25, 2026

Connect accepted project work with available delivery hours, client obligations, billing assumptions and the dates cash can actually arrive.

A signed contract, a booked hour, an approved milestone and a bank receipt are different events. Start with the remaining work rather than the original quote. Identify skill constraints and client approval holds before converting an aggregate backlog into weeks of capacity. The service guides cover carried retainer hours, meetings, handoffs, travel, written-off hours and contract caps so each can enter the budget once.

Then connect delivery to receipts. A delayed acceptance can postpone billing, and a concentrated client receipt can leave a cash gap even when the project margin is positive. The forecast guides reconcile signed receipt and payment errors and distinguish a favorable timing movement from a permanent improvement. Contract terms and rates remain explicit user assumptions.
