Turn Google Workspace Into Your CRM and ERP, Without the Enterprise Price Tag
Most businesses don't need Salesforce or NetSuite. They need Sheets, Gmail, and Drive working together intelligently. I build that for you, usually live within 1–3 weeks.

The problem
Sound familiar?
Ops teams stuck moving data between sheets and SaaS tools need a system inside Workspace, not another subscription that half the team ignores.
Spreadsheets that don't talk
Sales, inventory, and finance live in separate tabs. Someone copies data by hand every morning.
CRM seats you barely use
Salesforce or Zoho licenses for 20 people, but half the team still lives in Google Sheets.
No IT team to build tools
You know what you need, but no in-house developer and agency quotes start at six figures.
Manual Gmail-to-Sheets entry
Form leads, email replies, and calendar events never land in your tracker without retyping.

Why Workspace
Google Workspace vs Salesforce or NetSuite
Your team already lives in Gmail and Sheets. Build on that foundation instead of a rip-and-replace migration.
| Factor | Workspace build | Traditional CRM/ERP |
|---|---|---|
| Per-user licensing | $0 extra (Workspace you already pay) | $25–150+/seat/month |
| Data location | Your Google account | Vendor cloud |
| Gmail & Calendar integration | Native, no middleware | Connectors or manual sync |
| Customization | Unlimited, you own the code | Plan limits & add-ons |
| Time to first working version | 1–3 weeks typical | Weeks of setup + training |
| Migration risk later | Extend in place, no rip-and-replace | Export pain if you outgrow it |

FAQ
Frequently asked questions
Straight answers on replacing Salesforce, data security, timelines, and cost vs SaaS licenses.
Can a Google Sheets CRM replace Salesforce or Zoho?
For many SMBs and teams under ~50 users, yes. If you need pipeline tracking, lead capture, email follow-ups, and reporting without per-seat fees, a custom Sheets + Apps Script system often covers 80% of what you pay Salesforce for. Enterprise compliance, complex territory rules, or 500+ user sales orgs may still need dedicated CRM software.
What happens if my team grows past Google Sheets limits?
Sheets handles millions of cells when designed well. For high-volume data I use batch processing, archive tabs, BigQuery export, or split workbooks by department. Most CRM/ERP builds serve 5–50 users comfortably. We scope capacity during discovery so you know the ceiling before build starts.
Do you maintain the system after launch?
Yes. Every project includes documentation and a handover walkthrough. Optional maintenance at $50/hr covers trigger fixes, Google API changes, and feature additions as your process evolves. You own all source code in your Google account, so you are never locked in.
Is my business data secure in Google Apps Script?
Scripts run inside your own Google Workspace. Data stays in your Sheets, Drive, and Gmail. I build with minimum OAuth scopes, Script Properties for secrets, and protected ranges. I never host or store your operational data on external servers.
How long does a typical CRM or ERP build take?
Focused CRM builds (pipeline, contacts, tasks, Gmail automation) often go live in 1–3 weeks. Multi-module ERP systems with inventory, invoicing, and approvals typically take 3–6 weeks. I provide a fixed timeline in the scoping doc before development starts.
How much does it cost compared to SaaS CRM licenses?
Most builds land between $2,000 and $15,000 as a one-time project at $50/hr or fixed price. A 15-person team paying $25/seat/month for Salesforce spends $4,500/year before add-ons. A custom Workspace system pays for itself in months and you stop paying per user.
