Custom software development services, from architecture to production.
J14 is a bilingual custom software development company. We design the data model, APIs and integrations first (QuickBooks, Shopify, CRM and ERP), then ship tested software your team uses every day, from a 4-week MVP to a full operations platform.
Example: a client onboarding form written in TypeScript (left) and the same form in production, syncing with QuickBooks Online (right).

Quick Answers
What kinds of companies do you work with?
Mostly small and growing businesses, founder-led ventures, and operations that need custom software, integrations, AI-ready systems, or stronger infrastructure. Many of our clients are in the United States or Latin America and need a team that can translate business priorities into technical execution — quickly and without hand-holding.
Do you only build full custom platforms?
No. Some engagements are full platforms. Others are a single integration, a dashboard, a reporting layer, an API, a cloud infrastructure improvement, or a modernization of one specific workflow. We define the right scope based on what the business actually needs — not on what makes the largest project.
Can you integrate with QuickBooks, ERP, CRM, or other business systems?
Yes. Integration is one of our strongest capabilities. We connect finance, operations, reporting, websites, internal platforms, customer systems, and third-party tools through REST APIs, webhooks, middleware, and structured synchronization processes. If two systems need to share data reliably, we can build the connection.
How fast can a project start?
Faster than most companies expect. One of our core advantages is that we move quickly once the diagnosis and architecture are clear — and we are structured to get there efficiently. We work with companies that need momentum, and we design delivery to show visible progress as early as the first phase.
Do you have experience with AI and machine learning?
Yes — and our approach is practical, not experimental. We work on AI-ready data models, TensorFlow workflows, Vertex AI pipelines, orchestration patterns, retrieval-based systems, and business-focused AI implementation. The goal is always to align AI with real workflows, usable data, and outcomes the business can measure.
What makes J14 different from a typical development agency?
Most agencies are optimized for design projects or marketing deliverables. We are a technical and business partner for companies that need architecture, systems thinking, serious integrations, and execution at an enterprise level. Clients come to us when the software has to support real operations — not just look professional on a screen.
Do you support clients after launch?
Yes. Our engagements do not stop at delivery. We support systems after launch through optimization, monitoring, cloud management, maintenance, new module development, additional integrations, and continuous evolution — as long as the business needs it.
What is the savings calculator for?
It helps leadership quantify the return on a software investment before committing to it. Instead of evaluating a project purely on development cost, the calculator estimates how process improvement, automation, integration, and better reporting translate into recovered time, reduced overhead, and operational gains. It makes the case for technology in business terms.
