Deposit Invoices and Progress Billing: A Practical Guide

Wait until the end of a project to bill and you’re financing the whole job yourself: your hours, your materials, your risk. Deposits and progress billing spread payment across the project so your cash flow tracks the work. Clients accept both readily when they’re stated up front. They resist both when they appear mid-project. That timing difference is the whole game.

When to Ask for a Deposit

• New clients with no payment history
• Jobs where you buy materials before starting: construction, landscaping, custom fabrication
• Bookings that block out your calendar, like photography, events, or consulting engagements
• Any project long enough that a client walking away mid-job would hurt
• Custom or made-to-order work you couldn’t resell if the client vanished
• Clients who took weeks to approve the estimate. Slow approval often predicts slow payment.

How Much Is Standard

25-50% is the broad norm for service work. Materials-heavy trades often charge the full expected materials cost plus a portion of labor up front, so a client’s change of heart never leaves you holding inventory. Session-based businesses (photographers, tutors) tend to use a flat, non-refundable booking fee instead of a percentage. Whatever you choose, state it in the estimate. The deposit is part of the price conversation, not a surprise after approval.

Asking Without Losing the Job

Plenty of small businesses skip deposits because asking feels awkward, then spend the summer financing other people’s remodels. The awkwardness disappears when the deposit is framed as scheduling rather than suspicion: “A 40% deposit reserves your spot on our calendar and covers materials. The balance is due at final walkthrough.” Put that sentence in the estimate, before anyone has committed, and it reads as how you operate rather than a judgment about this client. And pay attention to how people react. A client who pushes back hard on a reasonable deposit is telling you how the final invoice will go, and it’s better to learn that before you’ve bought $3,000 of lumber on their behalf.

Invoicing a Deposit, Step by Step

1. 1State the deposit in the estimate: “40% deposit due before work begins; balance due on completion.”
2. 2After approval, send a deposit invoice for just that amount, clearly labeled “Deposit: [project name].”
3. 3Start work when the deposit clears. Not when it’s promised. When it clears.
4. 4On the final invoice, show the full project total, then the deposit as a credit line, then the balance due. The client should be able to see the whole story on one page.

Progress Billing for Longer Projects

Once a job stretches past a few weeks, split the price across milestones tied to visible progress: phases the client can walk through and verify, not dates on a calendar. In construction, it’s also common for clients to hold back a small retainage (often 5-10%) until final walkthrough. If you agree to one, put the release condition in writing before work starts, not after the walkthrough gets scheduled.

Milestones Clients Can Verify

The difference between smooth progress billing and a mid-project argument is how you define the milestones. “Rough-in complete” works because the client can walk through the house and see pipes in the walls. “50% done” invites debate, because percent complete is an opinion. Tie each payment to something visible or deliverable: demolition finished, cabinets installed, first design round delivered, draft sent. For a Cedar Home Services bathroom job, that might be three invoices: demo and rough-in, tile and fixtures set, final walkthrough. Write the milestone names into the estimate so everyone agrees on the checkpoints before money is attached to them, then invoice each one the day it’s reached instead of bundling them at the end.

Each milestone invoice is a normal invoice: its own number, its own due date, and a running summary showing the project total, everything billed so far, and what remains. That summary is what keeps the client feeling like they’re watching a plan unfold instead of being nickel-and-dimed.
