We turn complex ideas into high-performance software. Cutting-edge technology for companies that aim for market leadership.

Connect Your Technology, Unify Your Operation

Growing companies accumulate software: ERP, CRM, E-commerce, Marketing. The problem arises when they don't talk to each other. We build the bridges that connect your digital ecosystem.

Lack of integration leads to manual rework, inconsistent data and slow decision-making. At 300 Software, we specialize in building robust integration architectures. We develop secure APIs, microservices and middlewares that allow legacy systems to exchange data in real time with modern cloud applications, ensuring operational fluidity.

  • API Development (REST/GraphQL)
  • ERP Integration (SAP, Totvs, Oracle)
  • Microservices Architecture
  • Legacy System Modernization
  • Payment Gateways and Fintech
  • Real-Time Synchronization
  • Data Security and OAuth

How We Connect Everything

Our approach ensures that integration is invisible to the user but powerful for the business.

01.
Interface Mapping

We analyze all your current systems to understand communication protocols and the data that needs to flow.

02.
Integration Architecture

We design the ideal technical solution (API Gateway, ESB or direct connection) focused on security and low latency.

03.
Secure Implementation

We develop and test connections, ensuring data is validated and encrypted in transit.

Yes. We often create "modernization layers" (wrappers) that allow old systems without native APIs to communicate with modern software through database or file reading.

No. We carry out development in a parallel environment (staging) and plan go-live for low-impact times, ensuring business continuity.

Yes. We have experience integrating custom solutions with major market players (SAP, Salesforce, Microsoft Dynamics, Hubspot, Totvs), extracting and sending data according to business rules.

Security is a priority. We use modern authentication protocols (OAuth2, JWT), SSL/TLS encryption and API firewalls to ensure only authorized systems access your data.
