Intro

You work hard on site, but bills still pile up. Progress billing fixes that. It lets you get paid as you finish each stage, not months later. You protect your cash flow. Your crew stays busy. Your supplier accounts stay clean. In this guide, we’ll break down what progress billing is, when to use it, and how to write simple terms that clients accept. We’ll show easy schedules you can copy, how to invoice each milestone, and how to handle changes without fights. The steps are plain and practical. You can use them on your next job.

Quick Answer

Progress billing is a payment plan tied to project milestones. You bill a deposit, then invoice each stage as it’s done. Use clear scopes, dates, and approval steps. Keep milestones simple. Invoice fast with photos. This keeps cash moving and reduces disputes.

Key Takeaways

• Set 4–6 clear milestones. Keep each tied to visible work.
• Use simple percentages: deposit 10–20%, mid stages 20–30% each, final 10%.
• Define approval steps and due dates (commonly 7–14 days).
• Invoice same day the milestone is done. Add photos and notes.
• Handle changes with written approvals before work continues.

What Is Progress Billing?

Progress billing breaks one big invoice into smaller ones. Each bill matches a stage of work. When you finish the stage, you invoice it. The client pays as the project moves. This helps both sides. You keep cash coming. The client sees progress before paying more.

Use progress billing on jobs longer than two weeks. It fits renovations, additions, and multi-trade projects. It also works on fixed price or cost-plus jobs. The key is simple, clear milestones. Make them easy to see on site. “Rough-in complete” is clear. “50% done” is not.

Build A Simple Payment Schedule

A good schedule is short and clear. Aim for 4–6 stages. Tie each stage to work that’s easy to verify.

1. Deposit: 10–20% on acceptance. Covers booking, permits, and early materials.
2. After Demolition: 20–25%. Site is open. You’re ready for framing or prep.
3. After Rough-In: 20–30%. Electrical, plumbing, HVAC rough-in inspected.
4. After Finishes Start: 20–25%. Drywall, tile, flooring, or cabinets underway.
5. Substantial Completion: 10–15%. Space is usable. Minor items remain.
6. Holdback/Retainage Release (if used): typically after a set period, once all paperwork is done.

Adjust the percentages to match cash needs. Front-load materials you must prepay. Don’t overload the final bill. Clients resist big final payments. Keep the last invoice small, often 10%.

Put Terms In The Proposal

Your proposal should show the payment schedule, due dates, and what “done” means. Keep it plain:

• Scope per milestone: one or two lines. Clear and visible.
• Due dates: common terms are Net 7 or Net 14 days.
• Approval method: email reply, client portal, or signed form.
• Late fees: simple and fair. For example, a small monthly charge.
• Holdback/retainage: if required by contract or client. Show how and when it releases.

Capture details fast. Voice your notes, attach photos, and turn them into a proposal using tools like Donizo. Send the branded PDF, get an e‑signature, and move on. Clear terms up front reduce back-and-forth by half.

This pairs well with understanding invoice templates that save time and reduce mistakes.

Invoice Milestones The Right Way

When a milestone is done, invoice that day. Don’t wait 2–3 days. Add 3–5 photos. Add a short note: “Rough-in completed, inspected on Tuesday.” Attach any inspection slips or delivery notes.

• Reference the milestone name and number.
• Show the percentage and the dollar amount.
• Repeat the payment terms (for example, Net 7 days).
• Include how to pay. Keep it easy.

If a client questions a bill, be calm. Point to the scope, photos, and the signed proposal. Most disputes end there.

A Simple Example: 5-Stage Bath Reno

• Deposit 15% on acceptance. You order tile and vanity.
• After Demolition 20%. Site cleared. Any hidden issues noted.
• After Rough-In 25%. Plumbing and electrical rough-in inspected.
• After Tile Install 25%. Tile set and grouted. Shower sealed.
• Final 15% at substantial completion. Small punch list only.

Show total price and each stage value. Keep numbers round. Clients like simple math.

Manage Changes And Delays

Changes happen. Hidden rot. Client adds lights. Don’t mix changes into progress bills. Use a change order. Describe the change, price, and time impact. Get written approval first. Then invoice the change separately or add a new mini-milestone.

If weather or supply delays hit, update the schedule in writing. Push the milestone dates. Keep the sequence the same. Clear notes now save arguments later.

For contractors dealing with change orders, we recommend our detailed guide on change orders done right.

Common Mistakes To Avoid

• Vague milestones: “Half done” invites fights. Use visible work.
• Big final invoice: Keep it near 10%. Clients expect small at the end.
• No approval path: State who signs, how, and when.
• Slow invoicing: Same-day billing keeps cash moving.
• Missing holdback plan: Some contracts use holdback. Show release steps.
• No photos: Pictures end most debates in one email.

FAQ

How much deposit is fair?

In general, 10–20% is common. It should cover early materials, booking time, and admin. If custom items need full payment up front, explain that. Many clients agree when you show supplier quotes.

What if the client delays payment?

Send a polite reminder after the due date. Then call. Keep it short and calm. Stop work if needed, per your contract. Put this right in your proposal so it’s clear before you start.

How do I handle holdback or retainage in Canada?

Many contracts use a holdback or retainage. The amount and timing vary by province and contract type. Show the holdback on every invoice. State when it releases, and list required paperwork, like statutory declarations or waivers.

Can I use progress billing on small jobs?

Yes. Use fewer stages. For a two-week job, try 30% deposit, 40% mid-job, and 30% at substantial completion. Keep it simple and visible.

Should I use time-and-materials with progress billing?

You can. Bill a deposit, then weekly or at milestones based on tracked hours and materials. Share time logs and receipts. Clients trust clear records.

Conclusion

Progress billing keeps your cash steady and your projects calm. Keep milestones visible, terms simple, and invoices fast. Start with one current job. 1) Write 4–6 milestones. 2) Add due dates and approval steps. 3) Invoice the first stage the day it’s done. If you want less admin and faster sign-off, platforms such as Donizo help you turn site notes into signed proposals and convert approvals into invoices in one click. By setting clear steps now, you protect margin on every job.
