Start Free Trial →Consultant-Specific Pain Points
📅 Retainer Billing Headaches
Monthly retainers that roll over, expire, or get consumed at different rates. Spreadsheets break down fast.
📋 Project Phase Invoicing
Discovery, Strategy, Implementation, Review — each phase has different deliverables and billing rules.
📎 Deliverable-Based Billing
You bill when the deliverable is approved, not when the hours are logged. Tracking approvals is a nightmare.
💬 Scope Creep Without Billing
Extra "quick questions" and "small follow-ups" that add up to unpaid hours. Every consultant knows this pain.

Clients want to see what they got for their money. Creating usage reports takes hours you don't have.
