sales4.dev is the dev's sales cockpit. It finds the client, sends the proposal, follows your call and points out the bug that cost you the deal. You just code — the sales side runs on autopilot.
// built for anyone selling B2B services
They told you to "improve your portfolio". A lie. What's blocking your revenue isn't technical — it's what comes after the code: finding who pays, charging the right price, not ghosting on follow-up and not freezing when you hear "that's expensive". That's not in the docs.
Five steps. Each one solves a part of selling that costs you money today — and they all talk to each other.
too expensive
// example run
Finds businesses in your area with no website — your hottest lead — and fires the outreach on WhatsApp and email.
Automatic rotation across your WhatsApp numbers and email inboxes, with a daily cap by channel age. Volume without losing a number.
Unified inbox with AI suggesting the right reply to every objection. Your number, your tone — zero robot vibes.
Presentation, proposal and contract generated in your style from the client's brief. PDF in hand, no Canva.
Records your call, gives you a score and points out the bug that cost the "yes". Like code review — but for the conversation.
Scans Google Business by niche and region and automatically flags who has no digital presence — your hottest lead — dropping it straight into your funnel.
Connect your number (official or not) and send with anti-block pacing, your way — zero robot vibes.
Presentation, proposal and contract generated in your style from the client's brief — as PDF, ready to send.
Your Meet/Zoom calls become a score and a checklist of bugs. Each mistake links to the right lesson — you improve every conversation, not every year.
Every lead on a card, moving visually from "new" to "paid" — you never lose track of where each client stopped.
The "from prompt to paid" track — and the AI prioritizes the lesson for whatever you struggle with most, based on your own calls.
No API keys, no tools to sign up for, no need to understand sales. All the infrastructure is ours and runs invisibly behind the scenes. You connect your WhatsApp and that's it — the rest is already on.
You are already senior at code. The plan says where you stand at selling.
