Intro

On most jobs, problems start with unclear words, not bad work. Every contractor should do this: put the job in writing before any tool comes out. It protects you, your crew, and your client. It sets clear expectations. In this guide, you’ll learn exactly what to write, why it matters, and how to do it in under 30 minutes. We’ll use plain language. Clear steps. Real examples. Do this on small jobs and big ones. Every contractor should do this on every project.

Quick Answer

Every contractor should do this: lock down a written scope, price, timeline, payment schedule, and change-order process before work starts. Get a client signature, then convert it to an invoice after acceptance. This simple habit cuts disputes, protects margin, and saves 2–3 hours per week in back-and-forth.

Why Every Contractor Should Do This

Verbal deals fade. Memories drift. Photos and signatures don’t. Every contractor should do this because written terms reduce scope creep, missed extras, and unpaid time. They also speed decisions. When you show a client a clear plan, they say yes faster. It’s common for contractors to report fewer callbacks and smoother cash flow when everything is written.

On site, you make dozens of choices daily. A written scope keeps you aligned. It protects your margin. It protects your schedule. It protects your reputation. Every contractor should do this to avoid doing free work and to stop arguments before they start.

What to Put in Writing, Every Time

Here’s a simple checklist you can reuse. Every contractor should do this on every job, even small ones.

1. Client and site details
   • Full name, phone, email, site address. One point of contact.
2. Clear scope of work
   • Write what you will do in plain words. 5–10 bullet points is fine.
3. Exclusions and assumptions
   • List what you won’t do. Example: painting touch-ups, asbestos removal, permits by owner.
4. Materials and finishes
   • Brand, model, colour, grade. Note allowances (e.g., tile at $5/sq ft). Keep it exact.
5. Timeline and access
   • Start date window (e.g., within 10–14 days of deposit), working hours, site access needs.
6. Price and taxes
   • Show subtotal, taxes, and total. Note if pricing is fixed or time-and-materials.
7. Payment schedule
   • Example: 30% deposit, 40% mid-way, 30% at substantial completion. If your province requires a statutory holdback (commonly 10%), show it clearly.
8. Change-order process
   • All changes in writing, priced and signed before work continues. Target 1 business day for pricing.
9. Permits and inspections
   • Who pulls permits, who pays fees. State inspection requirements.
10. Warranty and call-backs

• Typical workmanship warranty is 12 months (check your local rules). Define what’s covered and response time (e.g., within 5 business days).

11. Site conditions and cleanup

• Debris removal, daily cleanup, protection. Note lead-safe rules if applicable.

12. Signature and date

• Both parties sign. No work without signatures.

Attach 10–12 photos to show existing conditions. Label them. Every contractor should do this to prevent “It wasn’t like that before” disputes.

How Every Contractor Should Do This: 7 Steps

Here’s a fast system you can run in under 30 minutes. Every contractor should do this the same way, every time.

1. Capture details (10 minutes)
   • Walk the site. Take 10 photos. Record a 2-minute voice note. Jot 5 key scope bullets.
2. Draft the scope (10 minutes)
   • Use a template. Write scope, exclusions, materials, and timeline. Keep sentences short.
3. Price it (5–10 minutes)
   • Insert your labour rate, materials, overhead, and profit. Show taxes clearly.
4. Set payments (2 minutes)
   • Example: 30% deposit to schedule, 40% mid-way, 30% at substantial completion. Add any 10% holdback line.
5. Add change-order rules (1 minute)
   • “Changes must be written, priced, and signed. Work pauses until signed.”
6. Send within 24 hours
   • Speed wins work. Aim for same-day on small jobs.
7. Get signatures before starting
   • No deposit, no permit, no start. Every contractor should do this without fail.

Tip: For follow-up, send one reminder at 24 hours, then call at 48 hours. Keep it polite. Keep it simple.

Tools to Help You Do This Fast

Many contractors find that the hardest part is writing the proposal quickly. Tools like Donizo help you capture project details by voice, text, and photos, then turn them into a branded PDF you can email. Clients can sign with built-in e-signatures, and you can convert accepted proposals to invoices in one click.

This pairs well with refining your professional proposals, tightening your project timelines, and standardizing your invoice templates. Every contractor should do this to work faster without losing accuracy.

What If Things Change on Site?

Things always change. Hidden rot. Missing blocking. Client picks a pricier faucet. No problem. Every contractor should do this when something changes:

1. Stop and document the change (5 minutes). Photo and 2–3 lines of text.
2. Price it the same day, or within 1 business day.
3. Send a written change order. Get a signature.
4. Update the timeline if needed (example: +2 days for special order).
5. Only then continue the changed work.

If you want a deeper dive into managing change orders, look for resources that show clear templates, approval flow, and how to protect your margin.

Common Mistakes to Avoid

• Starting without signatures
  • Don’t. Every contractor should do this instead: pause until signed.
• Vague allowances
  • “Nice tile” is not an allowance. Write “tile at $5/sq ft, labour included.”
• Missing exclusions
  • List 5–10 common exclusions on every job. It prevents free work.
• No photos of existing conditions
  • Take 10–12 photos. Label them by room or area.
• Confusing payment terms
  • Show the 3 milestones, taxes, and any 10% holdback. Keep it clear.
• Not sending fast
  • Proposals sent within 24 hours win more. Every contractor should do this to beat slow competitors.

FAQ

Do I really need a signed proposal for small jobs?

Yes. Even for a 2-hour service call, use a one-page scope, price, and signature. It takes 5 minutes and prevents disputes over “what was included.” Every contractor should do this, no matter the job size.

What if the client refuses to sign?

Stay polite, but don’t start. Explain that written terms protect both sides. Offer to walk through the scope on a 10-minute call. Every contractor should do this to avoid unpaid extras and schedule slips.

How detailed should exclusions be?

Very clear. List 5–10 items you’re not doing: paint, drywall past patch area, permits by owner, disposal fees, after-hours work, moving furniture, and so on. Every contractor should do this to keep scope tight.

Can I start before permits or deposit?

Don’t. Most problems begin here. Wait for signatures, deposit, and any required permits. Every contractor should do this to stay legal and protect cash flow.

How often should I update the client?

Weekly is enough on most jobs. Send a 5–10 minute update every Friday: what’s done, what’s next, and any decisions needed. Every contractor should do this to keep trust high and surprises low.
