We connect ERP, telematics, legacy applications, field tools, and back-office systems so operations stop running on manual exports, spreadsheets, and tribal knowledge.
What We Do
Most operationally complex organizations don’t need new software. They need the systems they already own to work together.
Seisan builds the connective tissue between ERP, CRM, telematics, work orders, field applications, IoT devices, and legacy databases. We turn fragmented data into a single operational picture, eliminate duplicate data entry, and give leadership the visibility to make decisions in real time instead of reconstructing them after the fact.
This isn’t middleware as a feature. It’s how your business actually runs.
Who It's For
This engagement is built for organizations dealing with fragmented data, reporting delays, and manual workarounds holding back execution. It’s especially valuable for leadership who know something has to change but want a smarter path before making a larger investment.
You’re a strong fit if your organization is dealing with:
• 3 or more core systems that don’t share data across a mid-market or enterprise environment
• A COO, CIO, CTO, VP Operations, or Director of Enterprise Applications overseeing operations
• $15M to $1B+ in revenue with field, fleet, or distributed operations
• Reporting that still depends on manual exports, spreadsheet reconciliations, or someone in finance who “just knows where the data lives”
• AI pressure with a data foundation that isn’t ready to support it
Problems We Solve
Your ERP has one version of a customer, your CRM has another, your field app has a third. Every report is a reconciliation exercise. Every executive question turns into a multi-day data hunt.
The dashboard reflects last week's truth, not today's. By the time you see a problem, the cost has already landed. Decisions get made on stale data because the live data isn't accessible.
Someone exports a CSV every morning. Someone else maps fields and uploads it somewhere. A third person catches the errors. None of this is the job they were hired for, and all of it breaks when they take vacation.
Every AI pilot eventually hits the same wall: the data isn't clean, isn't consistent, and isn't connected. Without an integration layer, AI is a science project. With one, it's an operational capability.
Our Core Offering
A phased modernization program that turns fragmented legacy systems into an AI-ready operating environment. Without forcing a reckless rebuild.
We start by understanding what you already own, where it breaks, and what’s actually slowing the business down. Then we design the integration, data, and workflow strategy that gets you to a modern operating environment one phase at a time.
• Legacy system and technical debt assessment
• Integration, API, and middleware strategy
• Data normalization and governance plan
• Workflow redesign priorities
• Targeted AI use cases tied to measurable operational outcomes
• Phased transformation roadmap with budget and risk view
Real Results
Seisan has built integrations across some of the most operationally complex environments in the country. Below are environments we’ve worked in.
Technology & Retail
Seisan integrated inventory, pricing, and fulfillment systems into a custom Android application for Intel’s Connected Store initiative. The result was a unified retail stack with real-time data accuracy across every store touchpoint.
Entertainment & Performing Arts
Seisan unified Sight & Sound’s ticketing, guest management, and operational platforms into a single system spanning reservation through arrival. The result was less operational friction and staff working from one accurate view of every visitor.
Professional Services
Seisan integrated a cloud-based database infrastructure connecting a custom mobile app to EY’s enterprise systems for 250,000+ global users, meeting enterprise-grade security, compliance, and performance requirements.
Most teams don’t need a bigger software footprint. They need the systems they already own to do more, talk more, and break less. Book a working session and we’ll walk through your current environment and identify the highest-value integration moves.
Got Questions?
Systems integration is the process of connecting different software applications, databases, APIs, and technology platforms so they work together as a unified system. This eliminates data silos, reduces manual data entry, and enables seamless information flow across your organization.
We integrate ERP systems, CRM platforms, databases, cloud services, legacy applications, APIs, IoT devices, mobile apps, and custom software. Common integrations include Salesforce, SAP, Oracle, Microsoft Dynamics, AWS services, and custom-built enterprise applications.
Simple point-to-point integrations can be completed in 4 to 6 weeks. Complex enterprise integration projects involving multiple systems, data transformation, and workflow automation typically take 3 to 6 months. We provide detailed timelines after assessing your specific integration requirements.
Yes. Legacy system integration is one of our specialties. We build middleware, APIs, and data bridges that connect older systems with modern cloud platforms and applications without requiring a complete replacement of your existing infrastructure.
We use a variety of approaches depending on your needs, including REST and SOAP APIs, message queues, event-driven architecture, ETL pipelines, middleware platforms, and custom integration adapters. We select the approach that best fits your technical environment and performance requirements.
We implement data validation, transformation rules, error handling, and reconciliation processes at every integration point. Our approach includes comprehensive testing with real data, monitoring for data quality issues, and automated alerts when discrepancies are detected.
Yes. We offer support and monitoring packages that include proactive monitoring of integration health, troubleshooting, performance optimization, and updates when connected systems change. This ensures your integrations continue to function reliably over time.
We have delivered integration projects across defense and government, healthcare, education, manufacturing, logistics, and professional services. Our experience spans highly regulated environments with strict compliance requirements as well as fast-moving commercial organizations.
