How many milestones should a project have?

Typically 3-5 milestones for most projects. Too few means large gaps between payments; too many creates administrative overhead. A common structure: deposit, mid-project, completion.

What if a client delays milestone approval?

Include approval timelines in your contract (e.g., "milestone deemed approved if no feedback within 5 business days"). This prevents indefinite payment delays.

Can I combine milestone and monthly billing?

Yes. Some businesses use milestone billing for project phases and monthly billing for ongoing support or maintenance after project completion.

How do I handle change orders with milestone billing?

Add change orders as additional line items on the current or next milestone invoice. If the change is significant, create a new milestone.

What percentage should the deposit be?

A 25-50% deposit is standard. Higher deposits are appropriate for custom or specialized work. The deposit should cover your initial costs and commit the client to the project.

Recurring Billing: Milestone Billing

Milestone billing invoices clients at predefined project milestones — key deliverables or phases — rather than on a fixed time schedule. Each payment is tied to completing a specific portion of work.

Pros & Cons of Milestone Billing

Advantages

+ Aligns payment with deliverable completion — fair for both parties
+ Maintains cash flow throughout long projects
+ Provides natural checkpoints for project review
+ Reduces financial risk for both client and provider

Considerations

- Requires clear milestone definitions upfront
- Delays in milestone completion delay payment
- Disputes over whether a milestone is complete can hold up billing
- More administrative tracking than simple monthly billing

Milestone Billing Best Practices

Define milestones clearly in the contract — specify what "complete" means for each phase.

Include a deposit milestone (20-50% upfront) to secure commitment before work begins.

Make milestone payments roughly proportional to the effort in each phase.

Invoice immediately upon milestone completion while the deliverable is fresh.

Include a final milestone for project closeout, handoff, and any remaining balance.

Build in a buffer milestone for testing, revisions, or change orders.

Common Milestone Billing Mistakes to Avoid

Vague milestone definitions that lead to disagreements about completion.

Backloading payments — too much of the total at the end creates cash flow problems.

Not including a deposit milestone, which means you start work with zero cash in hand.

Tying milestones to client approvals without specifying approval timelines.
