03 / Quarterly close

Know where you stand without waiting for your tax advisor.

With your invoices up to date, so are your numbers: what you have billed, what you have spent and an estimate of what you will owe the tax agency (Hacienda) this quarter. And when the time comes, everything collected in Taxaia is prepared to send to your tax advisor (gestor) with a link.

  • An estimate of what you will owe this quarter, based on your books as they stand today.
  • A read-only link with the whole quarter for your advisory firm (gestoría): no account, no chasing files.

✦ Quarter messenger

Before each Modelo 303/130 it prepares the link for your advisory firm and drafts the email. You send it.

The work moves forward.
The decision is yours.

You set the limits.

Tax actions and anything sent outside Taxaia need your approval. Every proposal keeps its source and its confidence level.

Why Taxaia

Others wait for your photo.
Taxaia reads your email.

01

It connects to your email

Most tools wait for you to take the photo or upload the PDF. Taxaia goes into your mailbox, recognises the invoices and brings them to your inbox without you lifting a finger.

02

You wait for no one to know where you stand

Your books and an estimate of what you will owe for the quarter update as invoices come in. No spreadsheet to fill in, no call to your tax advisor.

03

You approve from the platform

Every expense arrives with its data extracted and the original document alongside. One click to approve: the AI proposes, you decide.

VERI*FACTU invoicing

Every invoice keeps
its history.

Issued invoices are numbered, sealed and chained together, as Spain's VERI*FACTU rules require. You can trace each one and keep a record of every transaction.
