The onboarding roadblock: KYB API Integration to automate B2B client registration

"As a Cloud Specialist, it frustrates me to see B2B companies losing sales because it takes them two weeks to onboard a new corporate client. Asking for deeds, mercantile registry certificates, and validating the VAT number by hand via email is a bottleneck that cools down any negotiation. I design cloud API integrations that connect your ERP directly with mercantile and tax databases (like VIES, Informa, or Dun & Bradstreet), validating your client's legal identity instantly so they can start buying on the spot."

Does your administration department stall sales closures because it takes weeks to validate the legal documentation of a new corporate client?

For a B2B company, signing a large contract is only half the journey. Before you can invoice or grant commercial credit, you must perform the corporate onboarding process (Know Your Business or KYB). Your team has to chase the client to send incorporation deeds, powers of attorney, their Tax ID, and certificates of good standing. This manual paperwork, coupled with human validation on government websites, generates terrible friction that delays the first order, frustrates your sales reps, and gives a terrible image of corporate slowness.

The trap of Manual Searches in Public Registries

To try to verify tax data, some administrative staff spend the day copying and pasting VAT numbers into the VIES portal or downloading PDFs from mercantile registries. Turning your financial staff into internet detectives who validate documents by hand is the most inefficient way to scale your client portfolio.

Our solution: KYB Mercantile Validation API Architecture

At LANZA ESTUDIO, we digitize your risk and legal compliance. As Cloud engineers, we develop a secure Middleware that connects your CRM or ERP onboarding form directly with the APIs of global mercantile registries and tax authorities.

  1. Corporate Data Auto-Completion: By simply entering the Tax ID or company name, the Cloud API automatically extracts the registered address, legal name, and legal administrators.
  2. Intra-Community Tax Validation (VIES): The system queries European authorities in real time to confirm if the client is in the VAT Information Exchange System (VIES), applying the correct VAT instantly.
  3. Shareholder Structure Analysis (UBO): The integration automatically identifies the Ultimate Beneficial Owners (UBO) to strictly comply with international Anti-Money Laundering (AML) regulations.
  4. Automatic ERP Profile Creation: Once all mercantile parameters are validated, the architecture injects a 100% clean and verified client profile into your management software without anyone typing a single piece of data.

The Real Impact on your B2B Sales Cycle

  • Onboarding Reduced to Seconds: You transform a fifteen-day bureaucratic process into instant validation, allowing your new client to place their first order on the very same sales call.
  • Bulletproof Regulatory Compliance: You eliminate the risk of millionaire fines by systemically guaranteeing that all your clients comply with anti-money laundering laws before operating with them.
  • Error-Free Database: By extracting information directly from official registries, you eradicate returned invoices caused by typographical errors in the address or legal name.
