UlúApp · Waitlist

Complete customs files, without chasing anyone by email.

UlúApp keeps the file for every client and supplier of your brokerage. The holder uploads documents from a link, AI checks them against customs and tax regulations, and your team decides what's critical.

The problem

Your brokerage answers to the tax authority for every client's paperwork.

Today that work lives in emails, spreadsheets and shared folders, in the hands of very few people. Files arrive incomplete, expired or with data that doesn't match.

How it works

From the first document to the file the authority asks for.

Six steps in one place. Every step records who did what.

  1. 01

    You register the client

    You choose their profile (importer, exporter, individual or company) and UlúApp builds the document list that applies, with its legal basis.

  2. 02

    The holder uploads documents

    They get a link and a one-time code by email. They upload from their phone and always see what's missing and how to fix it.

  3. 03

    AI reads, classifies and cross-checks

    It checks each document against Mexican customs and tax law, extracts its data and flags what doesn't match between documents.

  4. 04

    Your team decides

    Approving or rejecting is always a person's call, with the file in view. If rejected, the holder gets the reason and how to fix it.

  5. 05

    Expiry dates watch themselves

    Reminders before each expiry, ten days of grace and a single escalation per file when something stays expired.

  6. 06

    The file, ready for the authority

    Your brokerage's Word forms pre-filled and the complete file downloadable in one click, with the log of every step.

Why it doesn't fail

AI helps. Rules and people decide.

UlúApp is built so a machine error never reaches operations without someone seeing it.

  • Critical documents always go through a person

    Articles of incorporation, powers of attorney and contracts go to human review by system rule, not by setting: nobody can skip it.

  • Auto-approval with a lock

    Only monthly renewals can be approved automatically, and only if a person already approved one, the reading has 0.9 confidence or more, the tax ID matches and the date is in the month. It ships off, and any approval can be sent back to review.

  • Data is cross-checked across documents

    If the company name, tax ID or address doesn't match between two documents, UlúApp flags it and someone confirms or corrects it.

  • The machine never stops the work

    If automatic review stops, the dashboard says so and the document goes to manual review. Your team keeps working.

  • When something fails, it says so

    No screen shows a quiet day when it actually couldn't query: every error says what happened and what to do.

  • Access with link and code

    The holder signs in with their signed link and a 6-digit code valid for 10 minutes with 5 attempts. Documents are served through short-lived links.

  • An audit log without personal data

    Every sensitive action is logged with who and when, without the document contents or the tax ID.

  • It learns from your team

    Each document a person approves teaches the system to classify the next ones better. Learning never approves or rejects on its own.

What needs attention first shows up first.

First client

Built with Injoy Agencia Aduanal, in Veracruz.

UlúApp was built with the team at Injoy, a customs and transport brokerage in the port of Veracruz, on their real operation: their holders, their document catalog and their expiry rules. Everything specific to each brokerage lives in configuration, so your file comes out the way your regulator requires.

The name comes from San Juan de Ulúa, the fortress in the port of Veracruz, the historic gateway of Mexico's foreign trade.
