General
We are a Mexican technology company with over 11 years of experience. We build proprietary platforms for CFDI 4.0 e-invoicing, invoice validation, AI transcription (Speech AI) and OSINT cyber-intelligence, plus custom software development, websites and CCTV security.
Reach out via the contact form or at contacto@viciousbyte.com. We offer a free initial consultation to understand your needs and propose the best solution. For online services (billing, validation, OSINT, Speech AI) you can subscribe directly from the Subscriptions section.
It depends on scope. A website usually takes 2–6 weeks; a custom system, 1–4 months. After the initial consultation we deliver a clear timeline with milestones and work with you throughout the process.
Yes. We work remotely with clients across the country, and our online platforms are available 24/7 from anywhere. For CCTV security we coordinate installation based on your location.
CFDI 4.0 Billing
Yes. Our platform stamps documents under the current SAT CFDI 4.0 standard, with seal validation and tax compliance. It is built for professionals, SMBs and enterprises.
Yes. We offer a REST API to stamp, query and cancel documents from your ERP, e-commerce or in-house system, with documentation and support. Ideal for automating billing at scale.
CFDI 4.0 stamping, an admin dashboard, PDF and XML generation, cancellations, reports and a REST API. Plans scale with your document volume; see Subscriptions for details.
Invoice Validation
It validates the structure and tax compliance of CFDIs: issuer and receiver Tax ID, SAT seal, validity and document status, among others. Ideal for audits and accounting control.
Yes. The platform is built for bulk CFDI validation, processing large volumes and returning clear per-document results. It also integrates via API.
Speech to Text (Speech AI)
Speech AI converts audio and video to text with high accuracy using AI models. Quality depends on audio clarity; it works great for interviews, meetings and multimedia content.
To transcribe interviews, meetings, calls, podcasts, classes and any spoken content you need as text. It automates transcription and saves hours of manual work.
OSINT Suite
It is our cyber-intelligence platform for digital investigations at scale. It runs OSINT queries across hundreds of open sources (social networks, forums and more) and generates reports with monitoring.
It delivers executive, evidence-ready reports in PDF, CSV and JSON, with data enrichment and cross-referencing. Built for teams that need consolidated, organized investigations.
Yes. OSINT works exclusively with open, public-source information. Responsible, lawful use is each organization’s responsibility; our platform is a professional tool for legitimate investigations.
Development & Websites
Two main areas: (1) Custom systems — web apps, enterprise management systems (ERP), REST and GraphQL APIs, admin panels, reports and analytics, and third-party integrations; and (2) Websites — corporate sites, online stores (e-commerce) and custom web applications. All built in-house at production quality.
Reference prices: corporate sites from $8,000 MXN, online stores (e-commerce) from $15,000 MXN and custom web apps from $25,000 MXN. These are "starting from" prices; the final cost is quoted based on scope. The initial consultation and analysis are free.
Custom systems start from $15,000 MXN per project, and the final price depends on scope and features. After the free initial consultation we deliver a clear quote. In the contact form you can indicate your budget range to guide the proposal.
We work in 4 stages: 1) Requirements analysis, 2) Design and architecture, 3) Development, and 4) Testing and delivery (deploy). After the initial consultation we deliver a timeline with clear milestones and support you throughout. For websites the flow is briefing and design → development → content and SEO → launch.
It depends on scope: a website usually takes 2–6 weeks, and a custom system 4–12 weeks. For websites we use an agile process (design in a few days, fast development, testing and optimized launch). The exact timeline is set in the proposal.
Responsive design (mobile, tablet and desktop), optimized SEO, a CMS to manage your content, contact forms and analytics. We also include a .com domain for the first year, an SSL certificate and professional hosting with high availability. For e-commerce we add catalog, cart, payment gateways and an admin panel.
A modern production stack: React and Next.js, Node.js, Python (Django), PHP (Laravel), Vue.js, TypeScript, SQL and NoSQL databases (PostgreSQL, MySQL, MongoDB, Redis), and cloud deployment (AWS, Azure, Docker). For websites we also use WordPress, Shopify, Strapi and Tailwind. We pick the right technology per project.
Yes. We build and integrate REST and GraphQL APIs, and connect with third parties: ERPs, e-commerce, payment gateways, and our own platforms (CFDI 4.0 billing, validation, Speech AI, OSINT). If you already have a system, we integrate it; if you start from scratch, we design it to scale.
Yes. All our sites are responsive (mobile, tablet and desktop), fast and search-optimized (technical SEO), following best practices for performance and accessibility.
Yes. For websites we offer a free demo and a no-cost initial consultation and analysis, so you can see a proposal before deciding. Reach us via the contact form and we’ll set it up.
Yes. We offer maintenance, updates and ongoing support after launch so your product keeps running securely and reliably. Maintenance plans are agreed based on your needs.

CCTV Security
We install professional IP video surveillance with high-resolution cameras, secure recording and storage, to quality standards. We design the solution based on your site’s size and needs.
Yes. The systems allow real-time remote monitoring from your phone or computer, so you can watch your property from anywhere.
Subscriptions & Payments
Our online services run on a subscription basis and are available 24/7 from anywhere. You pick a plan, create your account and activate the service instantly. You can view plans and subscribe directly from the Subscriptions section of the site.
Four online platforms: Electronic Billing (CFDI 4.0), Invoice Validation, Speech to Text (Speech AI) and the OSINT Suite. We also offer Premium cybersecurity Guides, which are a one-time purchase (not a subscription). Development, website and CCTV services are handled per project, not by subscription.
There are plans for each service, with prices from $240 MXN/month, varying by service and the volume you need (for example, billing documents). Each service has its own tiers. Check the up-to-date prices and pick yours in the Subscriptions section.
Yes. Most services offer a monthly plan and a yearly plan. The yearly plan is usually worthwhile if you use the service continuously. You can compare both on each service’s page before subscribing.
Plans are shown with their base price, and at checkout you’ll see the breakdown: base + VAT (16%) + total. Charges are made in Mexican pesos (MXN). Premium Guides are charged as a one-time payment.
We accept credit and debit cards through MercadoPago, a secure payment gateway. Charges are in Mexican pesos (MXN). For enterprise plans or custom projects we can arrange other options; write to contacto@viciousbyte.com.
Yes. Payment is processed through MercadoPago over an encrypted connection; your card data is handled directly by the gateway and is not stored on our servers. The site uses end-to-end HTTPS.
It’s quick: 1) Pick the plan on the service page; 2) create your account with your email (or sign in if you already have one); 3) we confirm the plan; 4) you pay by card via MercadoPago; and done, your service is active. You’ll see a confirmation at the end.
Subscriptions do not include a free trial period. What we do offer at no cost is an initial consultation to advise you and choose the right plan, and for websites a free demo. If you’re unsure which plan fits you, reach out and we’ll guide you.
Yes. Subscriptions auto-renew at the end of each period (monthly or yearly) so your service isn’t interrupted. You can manage or cancel the renewal according to your plan’s terms. Premium Guides are a one-time purchase and do not renew.
Yes. You can change plans (upgrade or downgrade) or cancel according to your subscription terms. If you need help with your account, a plan change or your billing, contact us at contacto@viciousbyte.com and we’ll gladly assist.
