Agency Invoice Generator — Milestones, Retainers & IP Clauses

When an agency bills a milestone, the invoice should reference the exact contract phase — not just 'services rendered.' Our template lets you tie each line item to a specific deliverable (e.g., 'Phase 2: UX Design Prototype — 35% per MSA §4.2'), so the client's CFO can cross-reference against the signed agreement.

Separate your monthly retainer hours from any overage work, list overage at the pre-approved hourly rate, and append a standard copyright transfer clause that triggers on full payment. All fields are editable; nothing is locked behind a paywall.
