Building a Lightweight CRM with Google Sheets and PostSheet

Most CRM tools are… a lot. Complicated setup, high cost, endless features you’ll never use.

But if you’re just trying to track contacts, send personalized follow-ups, and stay organized — you don’t need Salesforce or HubSpot.

You need a lightweight, flexible system. One you can build with tools you already use: Google Sheets + PostSheet.

In this post, we’ll show you how to build your own simple CRM that’s powerful enough to manage leads, clients, and outreach — without the bulk.


Why Build Your Own CRM in Google Sheets?

✅ It’s free
✅ It’s flexible
✅ Everyone on your team already knows how to use it
✅ It works perfectly with PostSheet for email, follow-ups, and document creation

It’s the perfect combo for early-stage teams, solopreneurs, agencies, and anyone who wants full control — without the tech headache.


What You Can Do with a Google Sheets + PostSheet CRM

📇 Manage leads and contacts
📬 Send personalized emails (cold outreach, follow-ups, nurture)
📄 Generate documents (invoices, proposals, contracts)
📅 Track deal stages or activity dates
🔁 Schedule recurring check-ins
📈 Analyze performance over time (win rate, stage conversion, etc.)

Let’s build it.


Step 1: Create Your CRM Spreadsheet

Start with a simple layout like this:

NameEmailCompanyStageLast ContactedNext StepNotes
Jamie Wongjamie@email.comAcme Co.Discovery2025-04-01Send proposal by FridayAsked for case studies
Leo Turnerleo@email.comBolt StudioFollow-Up2025-03-30Follow up in 3 daysInterested but hesitant

You can expand with fields like:

  • Role
  • Industry
  • Product Interest
  • Source
  • Lead Score
  • Closed/Won Date

Step 2: Set Up Email Templates in PostSheet

Write outreach or follow-up templates using merge tags from your sheet.

Example:

perl

Copy

Subject: Quick check-in with {{Company}}

Hi {{Name}},

Just wanted to follow up on our last conversation. You mentioned interest in {{Next Step}}, and I wanted to make sure you had everything you need.

Let me know if you’d like to set up a time to chat or if now’s not the right time.

Best,  

[Your Name]

You can send cold outreach, warm follow-ups, post-call recaps, or even post-sale thank-yous — all personalized, all fast.


Step 3: Segment and Filter in Your Sheet

Use filters or tabs to group contacts by:

  • Stage (Lead, Discovery, Demo, Closed)
  • Time since last contact
  • Activity (e.g. “Needs Follow-Up” = Yes)
  • Priority or deal size

This lets you run highly targeted outreach with just a few clicks.


Step 4: Use PostSheet to Send or Schedule Follow-Ups

With your filtered list:

  1. Start a PostSheet campaign
  2. Connect your CRM spreadsheet
  3. Map fields like {{Name}}, {{Company}}, {{Next Step}}
  4. Preview emails and send now or schedule for later

Want to send reminders or check-ins automatically every week? Easy.


Step 5: Automate Notes and Activity Logs

You can add columns like:

  • Follow-Up Sent?
  • Last Email Type
  • Response Date

Then use formulas or Zapier to update these fields as needed — keeping your CRM up to date without extra tools.


Add-On: Generate Docs from Your CRM

Need to send a proposal, invoice, or contract?

Use the same spreadsheet to generate custom PDFs in PostSheet:

  • Send an invoice based on Stage = Closed Won
  • Generate a proposal based on Product Interest
  • Share a welcome doc for Stage = Onboarding

All with the same workflow, all automated.
