Overview
app.itin.org is the platform where every ITIN.ORG client creates an account, uploads documents, signs, pays and tracks their ITIN until the IRS issues it — and where the team runs the whole business.
The challenge
Thousands of clients in dozens of countries, each with documents, contracts, payments and a long IRS process. Email and WhatsApp don't scale.
Our approach
One system with two sides: a simple, step-by-step portal for clients and a full back office for the team, with CRM, document review, billing and reports.
The solution
A multilingual client portal with e-signature and real-time tracking, plus a back office with CRM, contracts, invoices, collections and sales reports — all moved to its own cloud infrastructure.
What we built
- Step-by-step client portalPersonal details, documents, preparation and digital signature, with a progress bar and real-time ITIN status.
- Secure accessSign in with password or Passkey, two-step verification and bot protection.
- E-signature and contractsContracts and forms signed online and stored with each client.
- Document reviewClients upload passports and documents; the team approves or rejects them from the back office.
- Billing and collectionsInvoices, pay-on-approval plans, automatic reminders and payment links.
- CRM and sales reportsLead pipeline, follow-ups, monthly goals and sales reports for the team.
- Emails in 6 languagesRedesigned transactional templates: codes, invoices, reminders and welcome emails.
- Cloud and securityFull migration to GitHub and Render, documents in cloud storage and a security audit.
