How Deduce works inside Odoo: menus, scheduled task and the path of a capture

What Deduce solves, according to its listing

The module's listing starts from one idea: a receipt without your tax ID can't reclaim VAT. From there, Deduce reads the receipt or invoice the moment you capture it, tells you when to ask for a full invoice and posts the expense in Odoo. What's left for you is taking the photo and reviewing.

The listing sums up the flow in four moves: you snap a receipt, the AI reads it, Deduce tells you if you can deduct the VAT and you post it. Its motto is «zero typing»: the AI reads, you review. The rest of this article explains where each of those things happens inside Odoo.

The menus Deduce adds

Once installed, these entries appear, named exactly as they are in the module:

• Deduce › Captures: where captured receipts and invoices live.
• Deduce › Queues: a menu with several submenus underneath.
• Deduce › Cockpit
• Deduce › Form 303 preparation
• Deduce › Recoverable VAT (total)
• Deduce › Tax rules
• Deduce › Configuration

The Cockpit is a kanban view with one card per company. In the screenshot below, the My Company card brings together VAT at risk, captures to review, validated but not posted, duplicates and quarterly deductible VAT.

The scheduled task running in the background

Deduce ships with a single scheduled task, active out of the box:

• Name: Deduce: procesar capturas pendientes.
• Frequency: every 10 minutes.

Its name says what it does: process the captures that are pending. If you upload several captures in a row, this is the task that comes back to whatever is still pending every 10 minutes. If you deactivate it, it stops running, so it's worth checking it is still active after installing or updating the module.

The path of a capture, step by step

A new capture is opened from Deduce › Captures. The empty form already shows the pieces you'll work with: the Upload your file button, the destination (Vendor Bill in the screenshot), the merchant fields and the Tax details and Text / AI tabs.

This is the order in which you use it:

1. Go to Deduce › Captures and create a new capture. The form starts in the New state.
2. Upload the photo or file with Upload your file.
3. Choose the destination. The listing says a record can end up as a vendor bill or as an employee expense; in the example form the destination shown is Vendor Bill.
4. Let Deduce read the document. According to the listing, it reads it the moment you capture it; the Deduce: procesar capturas pendientes task also goes over pending captures every 10 minutes.
5. Review the data the AI has read. In the example in the screenshot below, the form shows that data, the Detalle fiscal tab and the Needs review state, with an OdooBot message in the chatter.
6. Read the deductibility notice. Deduce tells you whether you can deduct the VAT and when to ask for a full invoice; in the example a green deductible VAT notice is shown.
7. Post it. The listing states that Deduce posts the expense in Odoo.
8. Follow the whole picture from Deduce › Cockpit, where each company card brings together what is at risk, what is waiting for review and what is validated but not posted.

If you'd like to see the three screens in a row, this is the sequence:

The pieces working underneath

Behind the menus sit several Odoo models. Their technical descriptions help you understand what is stored and what is worked out:

• deduce.capture: the captured receipt or invoice.
• deduce.extraction.service: the extraction service, described as native AI plus an optional bring-your-own key. The listing puts it as «your AI or keyless, on your server».
• deduce.deductibility.engine: the EU VAT deductibility engine.
• deduce.rule: the deductibility rule, with editable limits. In the menu you'll find Deduce › Tax rules.
• deduce.nif.validator: a fiscal ID validator for ES, FR and DE.
• deduce.client.cockpit: the advisory cockpit per client.
• deduce.iva303.readiness: VAT-return readiness per client and quarter.

The listing mentions 10 countries, each with its own VAT rules. What the module applies in each case is whatever you have in its rules; don't treat it as settled legal advice and check it with your accountant.

Versions and price

Deduce is published on Odoo Apps for Odoo 17.0, 18.0 and 19.0, and the listing for each of those versions shows €39, a one-off payment per version, excluding VAT. You can check it on the Odoo Apps listing or on the module page.
