Thermotech Services Houston, TX

What was built

Started as a custom invoicing app built entirely in Spanish for a commercial refrigeration company, then grew into a full public website. The owner creates and edits invoices from his phone, tracks jobs and partial payments with automatic paid/pending status, and downloads a branded PDF invoice that matches the paper invoice book it replaced. The public site — services, photo gallery, and contact form — is entirely self-managed from the same admin login.

From a carbon-copy invoice book to one app plus a real website — all run from a phone.

▸ Invoicing side is private — full walkthrough available on request
