The problem

Month-end shouldn't feel like this

You chase invoices, bank statements, open items, your accountant… and end up running your company's accounting across WhatsApp, Excel, email and five different systems.

With CONTARO · one place
  • Your financial information, up to date
  • Invoicing, expenses and documents
  • Open items and obligations in plain view
  • Your accountant, in the same place

We think there should be a far simpler way.

What CONTARO is

Two things you normally buy separately

The software for running your company's books and the firm that keeps them. Together, for one flat monthly fee.

Normally bought separately

The software

A platform where you review and manage your financial information, invoicing, expenses, documents and open items.

  • Check your financial information whenever you want
  • Invoicing, expenses and documents in one place
  • Open items and obligations always in view

And this, hired separately

The firm

An accounting team that keeps everything running and makes sure your obligations are met correctly.

  • Monthly bookkeeping done by accountants
  • Taxes calculated and filed on time
  • Advice from someone who knows your company

At CONTARO

= one flat monthly fee

Software, automation, artificial intelligence and, above all, real people who answer for your accounting.

We don't hand you a tool and tell you “now use it to do your accounting”.

We give you the tool and we do the accounting with you.

How we work

Agents that never sleep. Accountants who answer

Our artificial intelligence agents work on your information 24/7. Behind them there is always an accountant who knows your company, reviews the work and makes sure everything gets done.

Always on

AI agents, 24/7

They do the heavy lifting every day, not only when the deadline is close.

  • Review your CFDIs one by one
  • Classify your transactions
  • Reconcile your bank movements
  • Catch open items before they become problems
  • Get your information ready for review
Answers for you

Your go-to accountant

One assigned person, with a name and a direct line. Not a call center, not a chatbot.

  • Knows your company and how it operates
  • Reviews the agents' work
  • Advises you on tax decisions
  • Answers for your obligations being met

The agents prepare. Your accountant decides, signs and answers. That is the difference between automating your accounting and having it handled.

How it works

Getting started takes minutes, not weeks

1

You connect

You add your FIEL, connect your banks and your systems. Your information stops living in five places and ends up in one.

2

The agents work

They review, classify, reconcile and catch open items every day — not only when the deadline is close.

3

Your accountant answers

They review the work, advise you and file your obligations. You log in to the platform and see everything handled.

One monthly fee

Like any subscription: it's all included

We want to be the Netflix of accounting. You pay one monthly fee and never see another hourly charge, surprise extra or invoice at the end of the month.
