The challenge
Small land-lot businesses run on paper plans, installment spreadsheets and manual collections. Getting late fees, interest and amortization right, without legal mistakes, is hard.
What I built
- Site-plan editor: upload a sketch and draw lots, blocks, curved streets and green areas on top. The plan is colored by each lot's status.
- Sales with reservation, down payment, grace period, financing interest (French amortization) and bonus extra payments.
- Per-project sales page with SEO: AI writes the headline and copy and generates the banner; the form creates leads automatically and shows live availability.
- Late fees capped at the legal usury rate; payments go to interest first, then principal, as Colombian law requires.
- Automatic PDFs: purchase agreement, amortization table, account statement, receipts and clearance letter.
- Per-company WhatsApp (linked by QR): installment plan, payment confirmations, reminders and overdue notices.
- Multi-company with a super-admin panel and admin and sales-agent roles.
Outcome
A land-lot business moves from paper and Excel to a system that attracts buyers, sells, collects and produces its own documents. In production with real projects.
