CORE CAPABILITIES

Built for high-volume enterprise throughput.

From manufacturing floor telemetry to complex multi-entity billing engines, we design resilient software architectures that eliminate operational friction.

Custom ERP Systems

Unified systems of record replacing disconnected legacy spreadsheets. Real-time production dispatch, bill of materials (BOM), inventory ledger, and departmental coordination.

Custom ERP Supply Chain BOM Ledger Telemetry

Multi-Tenant B2B SaaS

Scalable multi-tenant architectures with isolated schema security, custom billing tiers (Stripe/Paddle), subscription lifecycle management, and enterprise SSO (SAML/Okta).

6-PHASE DELIVERY LIFECYCLE

How we deliver custom enterprise software with zero operational risk.

Enterprise software failures occur when engineers write code before mapping workflow realities. We use structured dual-track modeling to eliminate adoption resistance.

01
Phase 1 · Week 1–3

Operational Audit & Domain Modeling

We shadow your teams, document existing Excel models and edge-case exceptions, and map the domain entities to produce an unambiguous system architecture specification.

  • Entity-Relationship Diagram (ERD)
  • State Transition Maps & Business Rules
  • Gap Analysis & Cutover Strategy
02
Phase 2 · Week 3–5

UI/UX & Operator Ergonomics

Custom software must be fast for daily power users. We design keyboard-first interfaces, dense data tables with instant filters, and mobile-friendly floor inspection screens.

  • High-Density Data Table Prototyping
  • Keyboard Shortcuts & Scan Gun UI
  • Clickable Workflow Demonstrations
03
Phase 3 · Week 5–7

Database & Core Engine Setup

Normalized relational schemas in PostgreSQL, Redis caching layers, ACID transaction boundaries, and automated audit logging hooks baked directly into the data access layer.

  • Strict Foreign Key & Constraint Schema
  • Immutable Change Data Capture (CDC)
  • Automated DB Migration Framework
04
Phase 4 · Week 7–14

Milestone Sprint Sprints

Dedicated engineering sprints delivering functioning modules every 2 weeks (e.g., Inventory module -> Dispatch module -> Billing module -> Analytics reporting).

  • Bi-weekly Staging Demos
  • Automated Unit & Integration Tests
  • Real-Time Jira / GitHub Progress
05
Phase 5 · Week 14–16

Shadow Testing & Data Migration

We run dual-track parallel operations where historical data is migrated and daily transactions run in both systems simultaneously to verify 100% financial and operational parity.

  • 100% Reconciled Financial Balance Checks
  • Operator Shadow Shift Dry Runs
  • Rollback Runbook & Disaster Drills
06
Phase 6 · Cutover & Dual-Track

Production Cutover & 90-Day SLA

Weekend final data sync, primary system cutover, on-site/virtual floor support during week one, and a 90-day comprehensive operational stability warranty.

  • Zero-Loss Production Cutover
  • Operator Training Videos & Docs
  • 90-Day Post-Launch SLA Warranty
ENTERPRISE INFRASTRUCTURE

The custom software stack built for 10-year durability.

We architect systems that outlast framework hype. Battle-tested relational engines, decoupled event workers, and clean containerized deployments.

FREQUENTLY ASKED QUESTIONS

Common questions about custom software & ERP development.

Straightforward answers regarding total cost of ownership, migration safety, and ongoing support.

Off-the-shelf ERP platforms charge massive annual per-user licensing fees ($150–$300/user/month), require expensive certified consultants for minor customizations, and force your business to conform to rigid software conventions. Custom software requires an upfront capital investment but incurs zero recurring seat licenses, perfectly mirrors your proprietary competitive advantages, and belongs 100% to your balance sheet as a corporate asset.

We utilize the Strangler Fig architectural pattern combined with dual-track ETL replication. Both old and new systems run concurrently during a 2 to 4 week validation window. Transactions are verified on both ledgers before flipping the primary operational switch on a scheduled maintenance weekend.

A phased implementation strategy typically launches the core Phase 1 operational module (e.g. inventory tracking or order dispatch) within 10 to 14 weeks. Subsequent departmental modules roll out incrementally every 4 to 6 weeks, allowing your staff to adapt smoothly without operational chaos.

Yes. We engineer bidirectional sync connectors for QuickBooks Online, Xero, Tally Prime (via XML/ODBC sync), Stripe, and bank feeds with automated reconciliation and error notification queues.

Data is encrypted at rest using AES-256 and in transit via TLS 1.3. We configure automated point-in-time recovery (PITR) backups with automated cross-region replication, role-based access control (RBAC), and immutable audit logs capturing every user edit.
