Our ERP development for Seattle builds or customizes ERP systems that handle industry-specific complexity while maintaining the financial accuracy and operational reliability that enterprise operations demand. Phase 1 — Requirements and System Design (3-4 weeks): understanding the operational requirements before selecting or building technology: operational analysis (documenting every business process the ERP must support — from procurement through production, inventory, sales, and finance — with specific attention to industry-specific requirements that generic ERPs miss — for Seattle: operational analysis includes regulatory analysis — identifying every FDA, NOAA, OSHA, L&I, and industry-specific compliance requirement the ERP must enforce), system evaluation (evaluating whether the requirements can be met through: commercial ERP customization (SAP Business One, Microsoft Dynamics 365, NetSuite, Sage — with industry-specific extensions and custom development), industry-specific ERP (platforms built for specific industries — Seasoft for seafood, SYSPRO for manufacturing, Acumatica for distribution), or custom ERP development (building a purpose-specific system when no commercial platform adequately handles the industry's unique requirements) — for Seattle: we recommend commercial platforms with customization when 70%+ of requirements are standard, and custom development when the industry-specific requirements are so extensive that customization would cost more than building purpose-built), and migration planning (planning the data migration and transition — mapping data from existing systems, planning cutover timing, and designing the parallel-running period — for Seattle: migration planning must minimize business disruption — seafood companies cannot afford ERP downtime during fishing season, and manufacturers cannot afford inventory accuracy issues during active production)). Phase 2 — Development (8-16 weeks): building or customizing the ERP: core module development (building or configuring the core ERP modules — financials (GL, AP, AR, fixed assets), inventory (receiving, storage, transfers, physical counts), procurement (PO management, vendor management, receiving), sales (order management, pricing, invoicing), and production (work orders, BOM, routing, shop floor control) — for Seattle: core modules must handle Washington State tax requirements (B&O tax, sales tax with complex nexus rules, and the absence of income tax which affects financial reporting)), industry-specific features (building the features that differentiate the ERP for the specific industry — for seafood: catch traceability, cold chain monitoring integration, species-specific grading, and export documentation — for manufacturing: AS9100 quality management, ITAR controls, aerospace BOM management — for multi-entity: intercompany transaction management, consolidated reporting, entity-specific configurations), integration (connecting the ERP with existing systems that will continue to operate alongside it — banking (payment processing and bank reconciliation), payroll (ADP, Paychex, or in-house payroll), e-commerce (for companies with online sales channels), CRM (for customer relationship data that supplements the ERP's customer master), and industry-specific systems (cold storage monitoring, shop floor data collection, EDI with trading partners)), and reporting and analytics (building the reporting layer — operational reports (inventory status, production progress, open orders), financial reports (P&L, balance sheet, cash flow, budget vs. actual), and management analytics (KPI dashboards, trend analysis, exception reporting) — for Seattle: reporting must satisfy both daily operational needs (a seafood plant manager needs real-time production and inventory visibility) and periodic compliance needs (FDA traceability reports, financial audits, tax filings))). Phase 3 — Migration and Go-Live (3-5 weeks): transitioning to the new ERP: data migration (migrating master data and transaction history — customer records, vendor records, product/item master, inventory balances, open orders, and financial balances — with rigorous validation to ensure accuracy — for Seattle: data migration must preserve the traceability and audit trail that regulatory compliance requires — historical lot traceability data and quality records must be accessible in the new system), parallel running (operating the new ERP alongside the existing system for a validation period — processing transactions in both systems and comparing results to verify accuracy — for Seattle: parallel running duration depends on industry — seafood companies need parallel running through at least one processing cycle, manufacturers need parallel running through a complete financial close), and go-live support (intensive support during the first month of live operation — on-site support, rapid issue resolution, and user assistance — for Seattle: go-live support must include competent help for the edge cases that only emerge in production — the unusual transaction types, exception scenarios, and regulatory situations that testing couldn't fully replicate)).
