Is your small business or freelance venture trembling at the obligation to connect your billing with the Tax Agency due to the new Anti-Fraud and Electronic Invoicing laws?
In Spain, sending certified electronic invoices to the Tax Agency is no longer optional. Small agencies, workshops, and entrepreneurs who bill using custom programs, foreign CRMs, or older systems are facing a concrete wall. Their software does not know how to talk to government servers. If you do not adapt in time, you face crippling fines that can wipe out your business numbers, and the countdown is running out day by day.
The trap of Buying a Corporate ERP out of Panic
Large software companies take advantage of this fear to force you to migrate to their cloud platforms, imposing abusive monthly fees and forcing your team to learn a complex system from scratch. Throwing away the software with which your small business works perfectly just to meet a tax requirement is an unacceptable technological hijack.
Our solution: Billing API Cloud Middleware
At LANZA ESTUDIO, we resolve state bureaucracy with invisible engineering. As Cloud architects, we design an intermediate layer (Middleware) hosted in the cloud that acts as the official and automatic translator between your current program and the Public Administration's API.
- Silent API Extraction: We connect our Cloud gateway to your current CRM, database, or Mini-ERP to detect every time you generate an invoice, without you having to press extra buttons.
- Transformation to Legal Format: The Middleware instantly converts your data into the standardized XML format required by law (FacturaE or equivalent European standards).
- Cloud Cryptographic Signature: We apply your corporate digital certificate automatically in a secure AWS or Google Cloud environment, sealing the invoice to guarantee its legal immutability.
- Bidirectional Communication with the Tax Agency: The API sends the document to state servers, manages response codes, and returns the verification QR to be printed on your PDF in a matter of milliseconds.
The Real Impact on your Tax Peace of Mind
- Guaranteed Regulatory Compliance: Your business is automatically shielded against tax penalties, operating under the strictest legal standard without any manual effort.
- Zero Learning Curve: Your employees continue billing exactly the same as yesterday, on the same screen as always, while data engineering happens invisibly in the cloud.
- Massive Savings on Software Licenses: You avoid paying the extortionate monthly fees of large corporate accounting programs, amortizing your private API gateway in just a few months.
