Every SMB I've worked with treats a Google Sheet as their first real database — leads, deals, inventory, campaign tracking. Then they buy a CRM and ask "how do we get the sheet into HubSpot/Pipedrive/Zoho?" There are four ways I've actually shipped this, and which one is right depends on volume, two-way needs, and how much code you want to maintain.

Here's the decision tree I use:

Need two-way sync?

├── No → Is your CRM's native Sheets connector free on your tier?

│ ├── Yes → Use that (15-min setup)
