Creating Custom Proposals from a Spreadsheet in Minutes

Proposals are a big deal.

Whether you’re pitching a service, scoping out a project, or quoting pricing for a lead — a clean, tailored proposal can make the difference between a closed deal and a cold lead.

But let’s be honest: creating proposals manually? Time-consuming. Repetitive. Error-prone.

With Google Sheets + PostSheet, you can create and send personalized, professional proposals in minutes — no design software, no Word templates, no copy-paste loops.

Here’s how to do it.


Why Automate Proposal Creation?

A great proposal is personalized, well-structured, and fast to deliver. But building each one manually is inefficient, especially when:

  • Your pricing, timelines, and deliverables follow a pattern
  • You’re working with similar client profiles
  • You’re responding to multiple leads at once

Automating this process means you can:

✅ Respond faster to leads
✅ Avoid errors in pricing or client names
✅ Deliver a polished proposal every time
✅ Free up time for follow-up and closing
✅ Scale your outbound or inbound sales process


What Kind of Proposals Can You Automate?

Just about any kind, including:

  • 🎯 Project scopes and timelines
  • 💼 Freelance service quotes
  • 🧾 Pricing breakdowns for SaaS or agency packages
  • 🛠️ Implementation or onboarding plans
  • 🧘 Workshop or course proposals
  • 📦 Bulk order quotes for eCommerce or wholesale

If your proposals follow a repeatable format, this is for you.


Step 1: Build a Spreadsheet with Client + Deal Info

Use Google Sheets to organize details for each proposal. One row per deal or client.

Client NameContact EmailProject TypeStart DatePriceDeliverables
Acme Co.jane@acme.comWebsite Redesign2025-04-15$8,500UI audit, dev, handoff
Bolt Techmike@bolt.comBrand Strategy2025-04-22$6,000Brand guide, messaging map

You can include as many fields as needed — deadline, contact person, billing details, etc.


Step 2: Design Your Proposal Template in PostSheet

In PostSheet, create a PDF proposal template using the fields from your sheet.

It might look like this:


Project Proposal: {{Project Type}} for {{Client Name}}

Start Date: {{Start Date}}
Price: {{Price}}
Deliverables:
{{Deliverables}}

Thank you for considering us for this opportunity. We’re excited to help {{Client Name}} move forward with this project.

Please let us know if you have any questions or would like to adjust the scope.

Best,
[Your Name]


You can add branding, format headers, and style the layout to match your brand. It’ll look like a custom proposal — but generated in seconds.


Step 3: Generate and Send in Bulk

Once your template is ready:

  1. Start a new document campaign
  2. Connect your spreadsheet
  3. Match your spreadsheet fields to the template variables
  4. Preview each proposal (PostSheet shows each one individually)
  5. Generate and send as PDFs — either by email or as a batch download

You can include a custom email like:

python

Copy

Hi {{Client Name}},

Attached is your personalized proposal for the {{Project Type}} project. Let me know if you have any questions, or if you’d like to hop on a quick call to review it.

Looking forward to working together!

– [Your Name]
