How to Send an Estimate to a Client (and Get It Approved)

EEstimateForge Team6 min read

Writing a strong estimate is half the job. How you deliver it — and what you do in the days following — determines whether it converts to a signed project or disappears into a client's inbox.

This guide covers the three main delivery methods, what to say in your cover email, when to send, and how to manage the approval process without chasing clients awkwardly.

The Three Delivery Methods

1. PDF Attached to Email

The default for most freelancers. You create a PDF estimate, attach it to an email, and send it.

Pros:

  • Familiar and expected in most industries
  • Clients can download and share internally
  • Professional appearance if the PDF is well-designed

Cons:

  • No visibility into whether the client opened it
  • Approval requires a reply email or a phone call
  • Easy to overlook in a busy inbox
  • Back-and-forth slows down the process

If you go the PDF route, make sure the file is well-named (e.g., Estimate_2026_ClientName_EST042.pdf, not draft_v3_FINAL.pdf) and that the PDF is actually formatted professionally — not a screenshot of a spreadsheet.

2. Online Estimate Link

Instead of a PDF, you send the client a link to an online estimate they can view in their browser. They can review, ask questions, and approve with a single click.

Pros:

  • You know when the estimate is opened
  • Approvals are instant — no printing, signing, or replying
  • Clients can view it on any device
  • Easier to present tiered options or accept deposits inline

Cons:

  • Requires a tool that supports online estimates
  • Some clients in traditional industries may prefer paper or PDF

Tools like EstimateForge let you build and share estimates as a link — when the client approves, you're notified immediately and can move straight to invoicing. For freelancers who deal with slow email responses, this removes a significant bottleneck.

3. Printed and In-Person

Still standard in construction, home services, landscaping, and some local trades. You print the estimate, present it in person or leave it with the client.

Pros:

  • Creates a personal interaction
  • Physical document is harder to ignore than an email
  • Right for clients who aren't email-first

Cons:

  • No way to update quickly if details change
  • Approval requires physical signature or a follow-up call
  • Slower and less scalable

If you deliver in person, bring a duplicate copy — one for the client, one for your records.

Writing the Cover Email

The estimate itself is the main document. The cover email is your introduction to it — brief, professional, and action-oriented. Many freelancers overthink this or, worse, send the PDF with no email body at all.

Here's what a good cover email does:

  1. References the conversation or project by name
  2. Summarizes what's inside the estimate (one sentence)
  3. States the next step clearly
  4. Makes it easy to ask questions

Template 1: New Client

Subject: Estimate for [Project Name] — [Your Business Name]

Hi [Client Name],

Thank you for the time earlier this week. As discussed, I've put together an estimate for the [project name] project.

The estimate covers [brief 1-sentence scope summary]. The total is [X], with [payment terms summary].

The estimate is valid for 30 days. To move forward, [state the next step — e.g., "sign and return the attached" or "click Approve on the estimate link"].

Happy to answer questions or set up a quick call if anything needs clarification.

[Your Name] [Title / Business Name] [Phone / Website]

Template 2: Existing Client (Repeat or New Project)

Subject: Estimate #[EST-XXX] — [Project Name]

Hi [Client Name],

As we discussed, here's the estimate for [project name].

Scope summary: [1-2 sentences]. Total: [X].

Same payment terms as last time — [X]% upfront, balance on delivery.

Let me know if you have questions, or just give the green light and I'll get started.

[Your Name]

Template 3: Sent Without a Prior Call (Cold or Inbound Lead)

Subject: Estimate for [Service Type] — [Client Company Name]

Hi [Client Name],

Thanks for reaching out. Based on your brief, I've prepared an estimate for the [project description].

Please note that this is based on the information provided — if the scope is different from what I've outlined, I'm happy to revise. The estimate is valid for 30 days.

I've included a short scope description in the estimate. If it looks right, [next step — e.g., "hit Approve on the link" or "reply to confirm and I'll send the deposit invoice"]. If you have questions, a quick 20-minute call would be the fastest way to align.

Looking forward to working with you.

When to Send the Estimate

Send within 24 hours of a discovery call. Speed signals professionalism and enthusiasm. Clients who are speaking to multiple freelancers are often won by the one who responds fastest and most clearly. Sending three days later, when the conversation has gone cold, reduces your conversion rate.

Don't send during off-hours if you want same-day attention. An estimate sent at 11pm Friday is likely to be buried by Monday morning. If you can, send Tuesday through Thursday, between 9am and 11am in the client's time zone. Not a hard rule, but worth thinking about.

Don't send before you have enough information. A poorly scoped estimate is worse than a slow one. If you need more information before you can price accurately, ask for it. A short intake form or a brief clarifying email is better than an estimate the client will question immediately.

Setting Expectations for Response Time

Don't let the estimate go out into the void with no timeline established. In your cover email or in a follow-up, communicate:

  • How long the estimate is valid
  • When you need a decision by to hold your availability
  • What happens next once they approve

This isn't pressure — it's logistics. "I have two spots starting May 1st, and this estimate is valid until April 30th" is honest and helpful.

The Approval Process

Define what approval looks like before you send. Ambiguity here causes delays.

For PDF estimates:

  • Ask the client to reply to your email confirming acceptance, or
  • Include a signature line and ask them to sign and return

For online estimates:

  • A click-to-approve button creates an immediate confirmation that's time-stamped

For in-person estimates:

  • Get a physical signature on a copy of the estimate before you leave

Once you have approval, send the deposit invoice immediately (if your terms include an upfront payment). The faster you get money moving, the less likely the project is to stall between approval and kickoff.

When They Don't Respond

No response within 48–72 hours is normal. Don't panic. Send a brief follow-up that's specific — not "just checking in" but something useful.

After that first follow-up, if you still don't hear back, you have two options: a second follow-up referencing the estimate's expiry, or letting the estimate expire and deciding whether to re-engage.

Common Sending Mistakes

Sending without a subject line that identifies the project. "Here's the estimate" tells the client nothing. "Estimate for Logo Redesign — EST-042" is scannable and searchable.

Attaching a generic filename. Estimate.pdf or draft_final_v2.pdf looks careless. Name the file clearly.

Apologizing for your price in the cover email. Writing "I know this might seem high" before they've even read it suggests you don't believe in your own pricing.

No clear next step. Every cover email should tell the client exactly what to do next. Don't leave it open-ended.

Sending the estimate and then immediately calling. Give them time to read it first. A call within 5 minutes feels like pressure, not follow-up.
