## **Short answer**

The Custom CRM Build is a CRM or client portal built around how you sell: your stages, fields and client view. It runs on the Workspace369 backend or fully custom in Vue/Nuxt or React on Firebase. A $450 written scoping in 3 business days picks the path and ends in a fixed build quote.

**$450**

### **Step 1: Scoping, $450**

- Your pipeline, stages, fields and roles, written down

### **Step 2: The build**

- The screens and flows in the agreed scope: pipeline, client pages, tasks, reports
- Sign-in and roles, so each person sees what they should
- Imports from your spreadsheet or old CRM, and the integrations named in the scope
- Deployed to your own accounts, with the code in your repository
- Handover notes and 14 days of written fixes for defects in the agreed scope

## Two ways to build it

The scoping picks the path that fits and says why. Both end with a CRM built around your process, deployed to your accounts.

### **Built on Workspace369**

Usually faster

Your screens and workflow on top of the Workspace369 backend. Clients, pipeline stages, custom fields, proposals, e-signatures, invoices and payments already exist there, so the build is only the part that is yours. Workspace369 is Simon’s own product.

- Your own app, connected over MCP or the HTTP API
- Permissions, approvals and an audit log already underneath
- Runs on your own Workspace369 plan: from $29/month, the HTTP API and webhooks on Specialist ($149/month) and up

**Best for service businesses that sell, sign, invoice and get paid.**

### **Fully custom**

Your stack

A CRM on your own database and cloud: Vue/Nuxt or React with TypeScript, on Firebase. The data model is built from scratch for your process.

- Deployed to your own Netlify, Vercel or Google Cloud account
- Connected to the tools you keep, such as Stripe, Twilio, SendGrid or your own backend
- No platform subscription, only your hosting

**Best when the CRM is part of a product you sell, or the data has to stay in your cloud.**

## This fits when

- Your pipeline lives in spreadsheets and nobody trusts them
- You bent an off-the-shelf CRM until it fights you
- Clients need their own view: a portal for files, approvals or invoices
- You want a fixed price instead of an open-ended hourly bill

Honest answer

## **You may not need a custom CRM**

Many freelancers and small agencies don’t. If your work runs lead, proposal, contract, invoice, a ready-made CRM is cheaper and you can start this week. The scoping tells you if this is you, and says so.

- The stages and fields a good CRM gives you are close enough
- You want it working this week, not after a build
- Your budget is a monthly plan, not a project

## How it works

1. 01 ### **Pay for scoping** Send how you sell today: your stages, a sample of your spreadsheet or CRM export, and the tools it must connect to.
2. 02 ### **Get the scope and quote** Within 3 business days: the path that fits, users and roles, screens, data, integrations, what waits for later, and a fixed price and timeline.
3. 03 ### **Build** If you say yes, the CRM is built to that scope, with progress shared in writing and your data imported before launch.
4. 04 ### **Launch and hand over** Deployed to your own accounts, with the code in your repository and 14 days of written fixes for defects in scope.

## **Building it yourself with Claude Code, Cursor or Lovable? Use Workspace369 as the backend.**

Your agent builds the screens. Workspace369 gives it clients, pipeline stages, proposals, e-signatures and invoices to read and write over MCP, so you skip building the backend. There is a build prompt to copy and a starter repo.

## Questions before you pay

<dl>

<dt>How much does a custom CRM cost?</dt>
<dd>The $450 scoping sets a fixed price for yours before you commit. The build is from $6,000, because a pipeline for one person and a portal for fifty clients are different jobs.</dd>

<dt>Should I build on Workspace369 or fully custom?</dt>
<dd>Workspace369 is usually faster when your work is selling, signing, invoicing and getting paid, because that backend already exists. Fully custom fits when the CRM is part of a product you sell or the data has to stay in your cloud. The scoping picks one and says why.</dd>

<dt>Is Workspace369 your product?</dt>
<dd>Yes. Simon builds and runs Workspace369. If the scoping finds that fully custom fits you better, the quote says so.</dd>

<dt>Can you move us off HubSpot, Pipedrive or a spreadsheet?</dt>
<dd>Yes. The import named in the scope moves your contacts, companies and deals from a CSV export. Moving years of history beyond that is quoted separately.</dd>

<dt>Do I have to go ahead with the build?</dt>
<dd>No. The written scope is yours to keep and use with any developer.</dd>

<dt>Is the $450 scoping credited toward the build?</dt>
<dd>Yes, credited in full against the build. Once you have the written scope, it isn’t refundable if you walk away, because you keep the scope.</dd>

<dt>What starts the 3 business days?</dt>
<dd>The materials arriving (stages, sample export, tool list), not payment.</dd>

<dt>How is the build itself paid?</dt>
<dd>Half on the signed scope, half on handover. No work before the first half.</dd>

<dt>Which payment makes the work mine?</dt>
<dd>Scope documents on the $450; code and files on the build payments.</dd>

<dt>Do I need a call before I pay?</dt>
<dd>No. The scope, price and delivery time are on this page, and everything happens in writing. If you want to talk live, calls cost $100 per 15 minutes, paid upfront.</dd>

<dt>Who owns what you deliver?</dt>
<dd>You do. The code, videos and files delivered under this offer belong to you once paid.</dd>
