How to Write an Estimate That Clients Actually Say Yes To
You've quoted a job. The client said "I'll think about it." And then... nothing.
If this sounds familiar, the problem might not be your price. It might be how you present it.
A well-written estimate does more than list prices. It builds trust, sets expectations, and makes the decision easy. Here's how to write one that works.
1. Start with Your Identity
Before the line items, establish who you are. Your estimate should include:
- Your business name — not just "John" but "John's Plumbing & Heating"
- Your contact info — phone and email so they can reach you
- Your license or tax ID — this signals legitimacy
CogniBill stores all of this in your business profile. Set it once, it's on every estimate.
2. Be Specific With Line Items
Vague estimates get rejected. Specific estimates get approved.
Bad:
- Plumbing repair — $500
Good:
- Diagnostic inspection of kitchen sink leak — $0 (free with service)
- Replacement of garbage disposal unit (InSinkErator Evolution Compact) — $249
- Labor: 1.5 hours at $85/hour — $127.50
- Haul away old unit — $25
- Total: $401.50
See the difference? The client knows exactly what they're paying for.
3. Use the Right Pricing Model
Most contractors charge one of three ways:
| Model | Best For | Example |
|---|---|---|
| Flat rate | Simple, predictable jobs | "Replace thermostat — $150" |
| Time + materials | Complex jobs with unknowns | "$85/hour + materials at cost" |
| Itemized | Jobs with multiple components | Each item priced separately |
Choose the model that fits the job. For complex projects, itemized is almost always better.
4. Include Payment Terms
Don't leave payment up in the air. Be clear:
- Due date: Due on receipt? Net 15? Net 30?
- Deposit: Do you require 50% upfront?
- Accepted methods: Cash? Check? Bank transfer? Credit card?
- Late fee: What happens if they don't pay on time?
CogniBill has built-in payment terms you can set per estimate.
5. Add Context with Photos (For Complex Jobs)
For repair jobs, before/after photos help justify the cost. For installations, a photo of the finished work shows what the client is paying for.
Note: CogniBill is an estimate and invoice app. For photo documentation, pair it with KeepProof — a local document vault on iPhone.
6. Handle Deposits and Installments
Some jobs require a deposit. Some have progress payments. Make this clear on the estimate.
Example:
- Deposit (50% due on acceptance): $750
- Final payment (due on completion): $750
- Total: $1,500
CogniBill tracks each payment separately so you know exactly where each client stands.
7. Follow Up
Most estimates don't close on the first send. Follow up after 3-5 days. A simple "Just checking in on the estimate I sent" email can recover 30% of "lost" jobs.
CogniBill doesn't have built-in reminders yet, but the overdue detection feature helps you prioritize follow-ups.
Putting It All Together
A great estimate is clear, specific, and professional. It answers every question before the client asks it.
With CogniBill, you can create one in under 3 minutes. The AI feature does the heavy lifting — just describe the job and it builds the estimate for you.
