So, is Google Sheets a CRM? Technically, it can hold CRM-style data — and for a solo founder with a simple sales process, a well-structured sheet with dropdowns, filters, and conditional formatting genuinely works. But as the research shows, the cracks appear fast: manual data entry breeds errors, activity history is the hardest thing to maintain, and once trust in the sheet fades, the whole system decays. Even the "free" math gets shaky — one analysis found a 10-person team's Sheets-based CRM setup can run about $310/month once you add Google Workspace and automation add-ons, per Capsule's cost breakdown. The real question isn't whether Sheets can store contacts — it's who follows up on them. If you're ready for a system where every lead is captured, followed up on, and remembered automatically — without you maintaining a single formula — AI Business Sites builds that CRM right into your website.
