B2B Lead Generation and Outreach SaaS

Project: Lead Finder + Outreach SaaS (LeadsFynder-style)
Goal (one line):
Build a multi-source B2B lead generation + outreach SaaS (similar to LeadsFynder) that pulls leads from Google Maps, LinkedIn, Facebook, and domains; includes verification, CRM-lite, email/WhatsApp outreach, analytics, admin controls, and tiered pricing.

Phase 1 (MVP – Must Have)
1. Auth & Billing
• Email/Google login.
• Stripe/PayPal/Razorpay/UPI integration.
• License system with feature flags per plan.
• Admin Panel Control: Change prices & create plans from admin → show directly on frontend.
2. Lead Sources
• Google Maps API (keyword + city search).
• Domain leads (upload CSV / auto-crawl contact pages, emails, socials).
• LinkedIn lite (public company page info).
• Facebook lite (page URL data).
• CSV import fallback.
• Duplicate Avoidance: If “Pet supplier in USA” searched today gave 200 leads, next search should skip already-given results and fetch only new ones.
3. Lead Manager (CRM-lite)
• Table view + filters (industry, location, rating, has email/phone).
• Lead scoring rules (customizable).
• Tags, notes, status (New, Qualified, Contacted, Won/Lost).
• Import CSV or Add New Lead manually.
• Call Log + Follow-up Calendar:
o Record conversation notes + response.
o Set reminder (e.g., “Call after 2 days”).
o Dashboard shows “Today’s Follow-ups” with last call summary & what to ask next.
4. Email Verification
• API integration (NeverBounce/DeBounce etc.).
• Flags deliverable/risky/unknown/disposable.
5. Outreach (Basic)
• Connect any SMTP (Gmail OAuth, Mailgun, SendGrid, SMTP2Go, Postmark, Zoho, etc.).
• Send 1-by-1 or bulk emails via connected SMTP.
• Sequences (1–3 steps) with spintax & custom fields.
• Clean, modern email sending UI (easy view of status).
• Daily send caps + pause on bounce/spam.
• Master Inbox (IMAP) for replies.
6. WhatsApp Integration
• Flexa Wapi official API for bulk send.
• Also via QR login (note: may risk account block).
7. Analytics
• Metrics: lead sources, email sends/opens/replies, verification stats.
• Export CSV/PDF reports.
8. Admin Panel
• Manage users, plans, pricing, usage, rate-limits, API keys.
• Control which features are active in each plan.

Phase 2 (Add-Ons)
• Unlimited Pack: remove caps, weekly DB refresh, verifier credits.
• AI Personalization: AI snippets for first lines/subject lines.
• Multi-Channel: WhatsApp API, SMS (Twilio/MSG91), LinkedIn helper.
• Reports Suite: SEO/Business/Accessibility reports.
• Team/Agency: sub-accounts, role permissions, activity logs, white-label.

Tech Stack (preferred)
• Frontend: React/Next.js + Tailwind.
• Backend: Node.js (NestJS/Express) or Python (FastAPI).
• Database: Postgres + Redis.
• Queues: BullMQ/Celery.
• Hosting: Docker.
• Designs: Figma (responsive).

Deliverables
• Full source code (frontend + backend) + Docker setup.
• Env templates & setup docs.
• Figma design files.
• Postman collection / OpenAPI spec.
• Demo data + tests.
• PDF process guide.

Pricing Models
• Front-End Plan ($27): Search caps, basic filters, CSV export, SMTP send, 100 verifier credits.
• Pro Unlimited ($67): Unlimited searches, advanced filters, 5k verifier credits/mo.
• Add-ons: AI ($29), Multi-Channel ($39), Reports ($29), Agency ($59).
