Contractors typically need four main types of business documents:

**Estimates**: Approximate pricing before scope is fully defined. Used for initial client discussions and job bidding.

**Quotes**: Fixed pricing commitments for defined work. Used when you can accurately price a job.

**Proposals**: Comprehensive documents that sell your approach. Used for larger projects where clients evaluate multiple options.

**Invoices**: Payment requests for completed work. Used to get paid and create documentation.

**Supporting documents you may also need:**

- Contracts or work agreements

- Change orders

- Lien waivers

- Completion certificates

- Warranty documents

Each document serves a specific purpose in the client relationship lifecycle.

Understanding when to use each document:

**Phase 1: Discovery**

Client calls about a bathroom renovation. You visit the site.

→ **Use: Estimate** (scope is unclear, conditions unknown)

**Phase 2: Scope Definition**

After assessment, you understand exactly what is needed.

→ **Use: Quote** (you can now commit to pricing)

**Phase 3: Selling the Project**

Client is comparing you to competitors.

→ **Use: Proposal** (differentiate yourself, not just pricing)

**Phase 4: Agreement**

Client accepts your quote or proposal.

→ **Use: Contract** (formalize the legal agreement)

**Phase 5: Work and Payment**

Work is completed or milestones are reached.

→ **Use: Invoice** (request payment for completed work)

Not every project follows all phases. Small jobs might go directly to quote; large jobs might require detailed proposals.

Estimates are where most client relationships begin. Make them count.

**What to include in contractor estimates:**

- Your business name, license numbers, insurance info

- Client name and job site address

- Detailed scope description

- Material estimates (allowances for selections)

- Labor estimates

- Permits and fees

- Contingency amount (typically 10-15%)

- Clear "estimate only" language

- Validity period

**Estimate best practices:**

- Visit the job site before estimating—never guess

- Document assumptions clearly

- Take photos for your records

- Provide ranges when uncertain

- Break out owner-furnished items separately

- Include what is NOT included

**Common mistakes:**

- Underestimating to win the job

- Forgetting permits, cleanup, or dumpster fees

- Not accounting for travel time

- Ignoring site conditions

- Leaving out contingency

When you are confident in scope and pricing, quotes demonstrate commitment.

**Contractor quote essentials:**

- Detailed scope of work—what exactly you will do

- Materials list (or allowances for selections)

- Specific timeline with start and completion dates

- Payment schedule tied to milestones

- Exclusions—what you will NOT do

- Change order process

- Warranty information

- Validity period (typically 30 days)

**Quote versus estimate decision:**

Use quotes when:

- You have complete plans or specifications

- Site conditions are known

- Materials are specified or can be accurately estimated

- Timeline is predictable

**Pricing strategies:**

- Include reasonable contingency in your pricing

- Consider material price fluctuation clauses

- Specify what requires change orders

- Be clear about scope boundaries

For larger projects, proposals differentiate you from competitors.

**When to use proposals:**

- Renovation projects over $25,000

- New construction bids

- Commercial work

- Any job with significant competition

**Proposal sections for contractors:**

1. Executive summary—the quick overview

2. Understanding of the project—show you get it

3. Your approach—how you will execute

4. Detailed scope of work—what exactly is included

5. Timeline with milestones

6. Investment breakdown—pricing tied to phases

7. About your company—credentials, insurance, references

8. Terms and conditions

9. Acceptance mechanism

**What makes contractor proposals win:**

- Photos of similar completed projects

- Specific references for similar work

- Clear timelines with realistic dates

- Communication plan during the project

- Clean, professional formatting

Getting paid properly requires proper invoicing.

**Contractor invoice essentials:**

- Invoice number and date

- Job address and description

- Work completed this invoice period

- Materials used (if billing separately)

- Labor hours or fixed milestone amount

- Contract amount, previous payments, current due

- Lien waiver status

- Payment due date and late fee policy

- Payment methods accepted

**Invoicing schedule:**

- Progress billing: Invoice at milestones (foundation, framing, etc.)

- Time and materials: Weekly or bi-weekly

- Fixed price: At project completion or percentage milestones

**Getting paid faster:**

- Invoice immediately upon milestone completion

- Include photos of completed work

- Reference contract payment terms

- Make payment easy (accept cards, offer ACH)

- Follow up before due date, not after

**Protecting yourself:**

- Send preliminary lien notices as required

- Track all payments against contract

- Document everything with photos

- Get signatures on completion certificates

Professional templates save time and ensure consistency.

**What every template needs:**

- Standard terms and conditions

- Clear formatting and professional fonts

**Template management:**
