The tax details of the order, checked for real

Ask for the NIF, NIE or CIF at checkout and check whether it is valid with the AEAT algorithm, not with a regular expression. It collects and sorts the data of the order; it does not issue invoices and it sends nothing to the Spanish tax agency.

What it does, in one sentence

It adds the tax fields the checkout is missing and makes sure that what the customer types is a valid document. It then leaves the data tidy inside the order, ready to be taken to your invoicing software.

It validates with the AEAT algorithm: the check letter of a DNI, a NIE and a CIF is really calculated, not matched against a text pattern. 12345678Z goes through; 12345678A does not.
It asks what the customer is: an individual, a Spanish company or a European Union company. The field changes name and format depending on the choice, and for an EU company it asks for the VAT number with its country prefix.
It shows the company name only when needed: for a company the field appears; for an individual nothing extra is asked.
It leaves the data on the order: the tax ID, the company name and the customer type are stored with each order and shown on its screen, in a row called «Bill to».
It exports a CSV with the tax details of every order in a date range, for your accountant or to import into another program.
It generates the tax QR of an invoice from the tax ID, the number and the amount, to print it or to check that the data adds up.
It tells you whether your shop is ready: a diagnostic screen that goes over what invoicing needs —the shop tax ID, the territory, the missing data in orders— and explains it in plain language.

What it does not do, and we say it plainly: it does not issue invoices, it does not number anything, it does not chain records and it sends nothing to the AEAT. That is Faro Factu SIF, which is another product. This is the plugin that collects the data and checks it.

A look inside

Getting started screen with the three steps — Getting started in three steps: your tax ID, the territory and a final check. You can skip it and come back whenever you like.

Checkout with the customer type selector and the tax ID field — At checkout: the customer chooses individual or company and the tax ID field changes with them.

Diagnostic screen — The diagnostic screen: what is fine, what is missing and what can be fixed, with the reason for each one.

CSV export screen — The export: pick a date range and take the tax details away in a CSV.

Tax QR screen — The tax QR, with the data of a sample invoice.

Three minutes to install

1Download and upload the ZIP

Plugins → Add New → Upload Plugin. You will also be able to search for «Faro Factu» in the installer once it is published on WordPress.org.

2Activate it and follow the guide

On activation a three-step guide appears: the shop tax ID, the territory and a check of what is still missing.

3Look at the first order

Place a test order and check that the tax ID reaches the order screen. If something does not add up, the diagnostic screen tells you.

Quick questions

Does this issue invoices?

No. It collects and validates the tax details of the order, nothing more. Issuing, numbering and sending to the AEAT belong to Faro Factu SIF.

Does it work if I only sell to individuals?

Yes. You can leave the selector on «individual» and ask only for the DNI, or remove the field altogether. With the tax ID validated you avoid the typing errors that later have to be fixed by hand.

Does it send the data anywhere?

No. Everything stays in your database. There is no account, no server of ours and no calls to the internet.

What happens if the customer leaves the tax ID empty?

You can make it required or not. If you leave it optional, the diagnostic screen tells you how many orders have no tax ID so that you can decide.

What about EU shops?

There is an «EU company» customer type that asks for the VAT number with the country prefix. That number is validated for format only: the VIES registration is still done wherever it belongs.
