Because you don't own anything. You rent their platform, live under their feature decisions, and the moment you stop paying the monthly fee your data, workflows, and automations disappear. CRM4Sale is a one-time purchase — you get the source, the mobile apps, and full control. No per-seat fees, no lock-in, no surprise pricing increases.

You can try. A realistic estimate: 3–6 months of full-time prompt engineering to get a multi-tenant CRM with email routing, SMS, voice, campaigns, AI compose, pipeline kanban, form builder, mobile apps, and a deployment pipeline. At a contractor rate of $100/hr that's $48,000–$96,000 before you've fixed a single production bug. CRM4Sale ships all of that — battle-tested — for a fraction of one month of that effort.

That's exactly what the AI Developer solves. Every install ships with a built-in tool that's fully trained on the codebase. Describe the feature you need in plain English, paste the output into Claude Code, and it's built — to the same conventions as the rest of the repo. No dev team, no tickets, no waiting. If you can explain it, you can have it.

Neither. You're getting a standalone, full-stack web application: PHP 7.4 backend, MySQL 8 database, Docker deployment stack, nginx reverse proxy, plus native iOS and Android companion apps. It's not a theme or a plugin — it's the entire working CRM that runs on your own server, behind your own domain, with your own branding.

No. You own the source code outright. It runs on your infrastructure, not ours. There's no license server to phone home to, no API key that expires, no dependency on us staying in business. The AI Developer panel, the deployment scripts, the docs — they all live inside your copy. You're self-sufficient from the moment you receive the handoff.

PHP 7.4 is the most deployed server-side language on the planet. It runs WordPress, Laravel, and most of the web's CRM infrastructure. The codebase is stable, well-documented, and every hosting provider on earth supports it out of the box. We chose boring on purpose — you'll never struggle to find a developer who can read this code, and the AI Developer is even better at PHP than most humans.

Every table that holds tenant data has an id_company column. All queries are scoped to the current company — there's no shared state between tenants. Super-admins can switch context between companies, but regular users only ever see their own company's data. This isolation is enforced at the ORM layer, not just the UI.

Anywhere. The reference deployment is DigitalOcean because it's simple and cheap ($48/mo for a single-tenant droplet), but the Docker stack runs on any Ubuntu box — AWS, Hetzner, Linode, bare metal, your closet. The rebuild script handles provisioning, but if you want to run it on your own infra the Docker compose file is the only dependency.

SendGrid and MailJet for outbound email, Nylas for inbox sync, Twilio for SMS and voice, Anthropic Claude for AI compose and the developer tools, Stripe for payments, Google Places for address lookup, and Sphinx/Manticore for full-text search across millions of records. Each integration has a working wrapper in the codebase — no SDK to install, just fill in the API key.

Yes. Full native iOS (Swift) and Android (Kotlin) source code. They use the same REST endpoints as the web app. Rebrand them, publish them to your own App Store / Play Store accounts, and ship them to your clients.

It's been running live across multiple agencies and industries for years. The deployment scripts, the email routing, the SMS pipeline, the cron jobs — all battle-tested on real data, real users, real SendGrid/Twilio accounts. We include a 90-day warranty because we're confident in what we're shipping, and the AI Developer gives you full transparency into every table, every file, every convention in the repo.

If a bug in the code we delivered surfaces within 90 days of your Google Drive handoff, we fix it — free, no arguments. That covers platform bugs, broken integrations that worked at delivery, config errors from our handoff process, migration issues, and security patches. It does not cover new features you build, third-party API changes after delivery, or upstream updates you apply yourself.

A senior full-stack developer costs $80–$150/hr. This codebase represents roughly 2,000–3,000 hours of work across backend, frontend, mobile, deployment, and integrations. At $100/hr that's $200,000–$300,000 — not counting project management, QA, or the months of production bug-fixing that you skip entirely. The first copy of CRM4Sale is $3,750.

Every copy comes with a 2-hour onboarding call, access to main-branch updates, and the 90-day warranty. Capping at four copies keeps that support realistic. The ascending ladder rewards early buyers — you get the same code at every tier, but buyer #1 pays $3,750 while buyer #4 pays $7,500. Once the fourth copy sells, the listing closes permanently.

Only hosting — roughly $48/mo for a DigitalOcean droplet (single-tenant) or $96/mo for a two-server setup with a dedicated search node. You'll also pay for your own SendGrid, Twilio, and Nylas usage at their published rates (all have generous free tiers). There are no per-seat fees, no monthly platform fees, and no recurring charges from us.
