Budgets and versions
From BC3, from Excel or by hand. Each change is a new version and you know which one the client accepted.
For building and renovation companies
Certify the work. Get paid what you’re owed.
Budget, progress certificates, invoices and payments for every job in one place. Retention and the construction reverse charge are applied for you.
With sample data. No sign-up needed.
Who it is for
Certifying, invoicing and getting paid for a project shouldn't need a separate spreadsheet.
64,271
construction companies in Spain have between 3 and 19 employees. That is the size Bildeit is built for.
Spanish National Statistics Institute (INE), Central Business Directory, data as of 1 January 2025: 35,474 construction companies with 3 to 5 employees, 16,409 with 6 to 9 and 12,388 with 10 to 19. INE press release, checked on 07/10/2026.
- 10%, 21% or no VAT chargedThe VAT on the same certificate changes depending on who the work is for.
- Months laterThe retention comes back when the guarantee ends. If nobody notes the date, it is claimed late.
- Two programs and a spreadsheetOne for the site, another for invoicing and a spreadsheet in between to reconcile them.
Step by step
How a progress certificate works
A €120,000.00 renovation, from the budget to the Verifactu record. These are screens from the real panel, with the demo's sample company.
-
01
You import the budget
In BC3, the industry's standard format, from Presto or TCQ; or from Excel; or by hand. You get the chapters and items, with a total of €120,000.00.
BC3 importedTotal: €120,000.00

02
You record progress
To date you are at 55%, €66,000.00. You had certified €36,000.00 before, so this certificate is €30,000.00.

03
The invoice comes out with its VAT
For a private client's home, 10% VAT: €31,500.00 to collect. For a developer on a new build, reverse charge and no VAT charged.

04
The retention is set aside
The 5%, €1,500.00, is set aside with its release date, and the panel warns you before it arrives.
5% retained: €1,500.00

05
The Verifactu record is kept
When issued, the invoice stores its record with a hash chained to the previous one and its QR code. Sending it to the tax agency comes once we choose the provider.
Invoice QR codeRecord created, not sent
What it does
From budget to payment, without copying a single number
Each card is a panel screen with the sample company. Everything here works today.
Payments and retentions
Each invoice with its due date and each retention with its release date, with a reminder beforehand.
The quarter, prepared
Forms 303 and 111, box by box, ready for your accountant. Bildeit prepares them; it does not file them.
Permissions by role
Office, site manager and accountant, each with their own. The database enforces it, not just the screen.
Connections
Works with what you already use
Only what works today. The bank and sending to the tax agency will appear here once they are really connected.

Verifactu
What it is and who it applies to
No small print, and with what Bildeit does today and what it doesn’t.
What it is
The new requirement for invoicing software. Every invoice creates a record with a hash chained to the previous one and a QR code, and that record is sent to the Spanish Tax Agency.
In Bildeit the record is already created when you issue. Sending is not there yet: it comes once we choose the provider that submits it to the Tax Agency.
Who it applies to and when
- 01/01/2027Companies (corporate tax)
- 01/07/2027Everyone else, self-employed included
Dates from Royal Decree-law 15/2025, consulted on 07/10/2026. On 05/10/2026 the Spanish Treasury announced a new postponement that has not yet been published in the BOE: we will update this when it is.
The chain of your invoicesEach record carries the hash of the previous one. If someone changes an invoice, the chain stops adding up.

Questions
What people ask before starting
With the real answer, also when the answer is no.
What works today?
Making the budget (imported from BC3 or Excel, or by hand), certifying progress to date and for the period, issuing the invoice from the certificate with its VAT, reverse charge and retention, seeing pending payments and retentions, recording supplier invoices with the 1% withholding, and preparing forms 303 and 111. The Verifactu record is created, but not yet sent to the tax agency: that comes once we choose the provider.
Does it work all over Spain?
Not yet. Bildeit calculates VAT for mainland Spain and the Balearic Islands. It does not cover the Canary Islands, where IGIC applies; Ceuta and Melilla, where IPSI applies; or the Basque Country and Navarre, which have regional tax authorities and their own invoicing system (TicketBAI in the Basque Country). When you create your company we ask for the province of your tax address and warn you if it falls outside.
Does Bildeit file my taxes for me?
No. It prepares them with your data and every figure broken down. Your accountant reviews and files them.
Is it accounting software?
No. It does no journal entries or annual accounts. It handles your jobs, your invoices and the VAT record books, which is what your accountant needs.
Can I bring my budgets?
Yes. In BC3, the industry's standard format, exported by Presto and TCQ, with chapters, items and measurements. Also from Excel or CSV, with summary, quantity and price columns. And if you have no file, you do it by hand.
Who can see my data?
Only the people in your company, each according to their role. The database enforces it row by row, not just the screen.
Can I take my data with me?
Today you can download the record books as CSV and each budget as Excel. Downloading everything at once is not possible yet.
We show you a whole job, with its numbers.
Half an hour, with your own budgets if you like. No commitment.
