Looking for AI Solutions?
If you need voice AI, intelligent copilots, or ML-powered automation, see our AI Solutions service. This page focuses on custom workflow applications that extend enterprise systems (SAP, Oracle, Salesforce).
You Need One Thing. They Want to Sell You $500K Worth of Everything.
You need a portal so suppliers can check their orders. SAP says "module." Oracle says "platform." They both come with 18-24 month implementations and $500K+ licenses. Half the features you'll never use. Months of configuration. And when you need to change something, you're calling support for a $10K change order.
There's a middle ground. A focused app that solves your specific 1-3 workflows. Pulls data from SAP. Writes confirmations back to Oracle. Gives your field team a mobile interface that actually works. No bloat. No features you don't need. Just the thing that solves the problem you actually have.
These apps cost 60-80% less and ship in 8-16 weeks instead of nearly two years. Your core systems stay untouched. You don't have upgrade conflicts. And when you need changes, you call us—not a support desk with a 6-week queue.
Business Impact
Cost Optimization vs. Enterprise Modules
Custom surround applications deliver specific workflows at 60-80% lower cost than full enterprise module implementations. Focus your budget on the workflows that matter, not comprehensive platforms with unused features.
8-16 Week Time-to-Value
Custom applications reach production in 8-16 weeks compared to 18-24+ months for enterprise module rollouts. Line of Business teams get working solutions before traditional implementations complete discovery.
Mobile-First User Experience
Field technicians, warehouse staff, and suppliers get intuitive mobile interfaces tailored to their specific workflows—not generic ERP screens adapted for mobile. Adoption rates improve dramatically with purpose-built UX.
Preserve Core System Investment
Your SAP/Oracle/Salesforce remains the source of truth. Custom apps extend capabilities without replacing core systems or disrupting upgrade paths. You get flexibility where you need it, stability where it matters.
Build vs. Buy: When Custom Apps Make Sense
Custom applications aren't always the right choice. Use this framework to evaluate your specific situation.
Consider Custom Apps When:
- You need 1-3 specific workflows from a larger system
- Off-the-shelf module costs $500K+ but you only use 20% of features
- Vendor pricing model doesn't match usage (paying per-seat for occasional users)
- You need mobile-first UX that the core system doesn't provide
- Integration between 2-3 existing systems for a specific process
- Timeline pressure (need production app in 8-16 weeks)
Choose Off-the-Shelf SaaS When:
- Ultra-detailed, complex requirements spanning 10+ workflows
- You need comprehensive, pre-built industry functionality
- Budget and timeline align with vendor implementation (12-18+ months acceptable)
- Compliance/audit requirements favor established vendor solutions
- Your team can adopt the vendor's prescribed processes
- Ongoing vendor support and updates are critical to your operations
Hybrid Approach: Many successful projects use a combination—core ERP/CRM for comprehensive processes, custom apps for focused Line of Business workflows that don't fit standard modules.

Frequently Asked Questions
When should I NOT use custom applications?
Custom apps aren't the right choice for comprehensive ERP replacement or when you need 10+ workflows spanning multiple business functions. If you have ultra-detailed, complex requirements requiring extensive pre-built industry functionality, an enterprise module or vertical SaaS platform is likely better. We help with focused, surround applications (1-3 workflows) that complement your core systems, not replace them.
Will this replace our SAP/Oracle/Salesforce system?
No. We build surround applications that extend your core systems, not replace them. Your ERP/CRM remains the source of truth for master data. Custom apps handle specific workflows, user experiences, or integrations that your core system doesn't address well.
What happens when our core system gets upgraded?
We use standard APIs and integration patterns that are designed to survive system upgrades. When your SAP/Oracle/Salesforce environment is upgraded, the custom application typically requires only minor updates to API endpoints or authentication—not a complete rebuild.
Who maintains the application after launch?
You have options. We can provide ongoing maintenance and support ($20-40K/year typical), you can bring maintenance in-house with your IT team, or use a hybrid approach. We provide full source code, documentation, and knowledge transfer to enable your team to take ownership.
How do you handle security and compliance?
We implement enterprise-grade security from day one: SSO integration, role-based access control, audit logging, and encryption at rest and in transit. For regulated industries, we design to your specific compliance requirements and standards.
Can you integrate with our legacy systems?
Yes. If legacy systems have APIs, we use those. If not, we explore database integration, file-based sync, or message queue patterns. During discovery, we assess what's technically feasible and recommend the most maintainable approach.
What if our requirements change during development?
We use an agile, sprint-based approach with weekly demos. Small scope changes are normal and expected. Significant scope changes are documented as change requests with updated timeline and cost estimates. Our goal is flexibility while managing expectations transparently.
Ready to explore a custom application for your workflow?
Schedule a 30-minute scoping call to discuss your specific workflow, integration requirements, and timeline. We'll provide an honest assessment of whether a custom application is the right approach.
No obligation. No sales pitch. Just an honest conversation about your needs.
