How to Automate Personalized Docs Like Proposals, Certificates, and Invoices with PostSheet

If you’ve ever copied a Google Doc, replaced a few names, downloaded a PDF, then emailed it to someone — you know the grind of “manual document creation.”

Multiply that across clients, events, or sales quotes, and it’s not just tedious — it’s a time suck.

With Google Sheets + PostSheet, you can instantly generate personalized, professional documents like proposals, certificates, and invoices — and send them automatically.

No design software. No manual edits. Just scalable, beautiful output.


Why Automate Document Creation?

Every personalized doc takes time. Automating this process helps you:

✅ Save hours every week
✅ Eliminate formatting and copy-paste errors
✅ Stay consistent across clients or recipients
✅ Deliver faster (and look way more professional)
✅ Scale without hiring more admin help

Perfect for freelancers, agencies, event organizers, coaches, and small businesses.


What You Can Generate with PostSheet

📄 Proposals & quotes — project scopes, pricing, timelines
🧾 Invoices — with payment info and due dates
🏆 Certificates — for course completions, awards, or achievements
📋 Reports — for client work or performance updates
📜 HR letters or contracts — formatted and branded

If it’s structured and repeatable, PostSheet can handle it.


Step 1: Set Up Your Spreadsheet with Dynamic Data

Let’s say you’re generating proposals. Your sheet might look like:

Client NameEmailProject NamePriceStart DateDeliverables
Acme Co.jane@acme.comWebsite Redesign$5,0002025-04-08Design, Dev, Launch Support
Bolt Studiomike@bolt.comBranding Package$3,2002025-04-12Logo, Style Guide, Templates

Each row becomes a personalized doc for that client.


Step 2: Create a Document Template in PostSheet

PostSheet lets you create and design a PDF or Google Doc-style layout using merge tags.

Example: Proposal Template


Project Proposal for {{Client Name}}

Project: {{Project Name}}
Start Date: {{Start Date}}
Total Investment: {{Price}}

Deliverables:

  • {{Deliverables}}

We’re excited to partner with you and bring this project to life. Let us know if you have any questions or revisions.

Best,
[Your Name]
[Your Company]


✅ You can add logos, format with headers and spacing, and reuse this template forever.


Step 3: Generate and Send in Bulk

Once your template is set, you can:

  • Generate PDFs for all rows at once
  • Preview each personalized version
  • Email the doc directly to the contact in your sheet
  • Or export them for download, upload, or printing

Want to attach a proposal to a personalized email? Easy — PostSheet handles both in the same workflow.


Other Use Cases You Can Tackle

  • 🧾 Invoices: Automatically send billing documents after service delivery
  • 🎓 Certificates: Generate custom completion certificates from a form submission list
  • 📊 Reports: Summarize project milestones, analytics, or deliverables for clients
  • 💼 HR Docs: Offer letters, promotion notices, confirmation letters
  • 🎫 Event Confirmations: Custom badges, attendee summaries, or ticket PDFs

If it lives in a spreadsheet, it can be automated.
