Your invoicing, compliant with Spain's new rules (RD 1007/2023), without changing systems.
We adapt the program you invoice with today and leave it compliant, tested before your real invoicing is touched.
Who it is for
Who it serves
Companies invoicing with a custom-built program, with aging software, or with one built for their sector and no route published by its maker. Also anyone running a system of their own that works well and that nobody is going to adapt for them.
Who it does not serve
If you invoice with SAP, A3, Sage or Holded, your vendor already covers this obligation. We will tell you on the first call, before there is a proposal. Simple sole-trader invoicing is solved by standard tools, and for that case they are the right answer.
What it does
- Diagnosis of your system
- How you invoice today is compared against what the rules require, and what is missing is set out point by point.
- Integration onto the system you run
- Every invoice is recorded and verifiable by the tax agency, on the system you already run and without replacing it.
- Testing before anything is touched
- The full circuit is validated in the tax agency's test environment before a single real invoice is issued.
- Go-live and record retention
- We support you through the responsible declaration and keep the records, with their integrity verifiable at any time.
The proof
We invoice on this same system.
Our own invoices are issued with the same system we install for you, accepted by the tax authority since July 2026. We have not read it in the regulation: we have done it in our own company.
The case it came from
Our own invoicing
In-house proof: AIdvance's own invoicing.
- The problem
- The new invoicing rules force changes, and many companies are told they have to change software.
- What we built
- A system that meets the new invoicing rules without forcing a change of tools, and we tested it first in our own company.
- The change
- From “I have to change software to comply”, to complying without breaking what you already use.
Why it exists
The obligation is yours and there is no vendor to call.
You invoice with a custom-built program from twelve years ago, or with one for your sector that nobody updates anymore, and it works perfectly. Replacing all of it to comply with a record-keeping rule is out of proportion.
Delivery
How it is rolled out
The system is already built and running. What gets designed in each case is the integration with yours, and you decide before a single line is touched. It is contracted as a fixed-scope project: quoted after the diagnosis and delivered turnkey.
Frequently asked questions
Frequently asked questions.
-
Do we have to change our program?
- No. The compliant record is built onto the system you already run: every invoice is linked to the one before it, carries its QR code and is submitted to the tax agency. Your team invoices exactly as it did yesterday.
-
What exactly is attested to the tax agency?
- The regime works by responsible declaration: it is you who declares that your invoicing system meets the requirements, and there is no seal the tax agency grants to software. What we deliver is the technical conformity of the system and the support through that declaration.
-
What if an outside IT provider maintains our program?
- We talk to them from the diagnosis onward. The integration is built on what already exists and whatever is touched is documented, so whoever maintains your program can keep doing it.
