Our ERP Application Development Process
A structured six-stage process designed to deliver an ERP your operations team actually adopts - from business process discovery and data modelling through modular development, integration, parallel run, and post-go-live optimisation.
We conduct structured workshops with your finance, operations, procurement, manufacturing, and HR stakeholders to map existing workflows, identify pain points, define data ownership, and establish integration requirements - before a single line of code is written.
Our architects design a modular, scalable ERP architecture with a unified data model - shared master data (entities, accounts, locations, products) with module-specific transaction tables, a clean API layer, and a reporting data warehouse decoupled from operational databases.
We build and deliver the core financial and inventory modules first, getting your team on live data quickly. Manufacturing, procurement, HR, and supply chain modules are built in parallel sprints, with biweekly demo releases on a shared staging environment.
All required integrations are designed, built, and tested - CRM, eCommerce, banking, logistics, EDI trading partners, tax engines, and BI tools. Integration monitoring dashboards with alert thresholds are delivered alongside each connector.
Full data migration from your legacy or interim system - GL balances, open transactions, vendor and customer master data, inventory, and historical records. A controlled parallel run period validates ERP data accuracy against your existing system before final cutover.
Staged go-live starting with pilot business units, followed by phased rollout. User training sessions, admin documentation, and an ERP helpdesk during the hypercare period. Post-go-live, new modules and features continue on a sprint roadmap.
What Our ERP Clients Say
Trusted by manufacturers, distributors, food and beverage companies, and enterprise operations teams across the US, UK, and Australia.
We replaced a decade-old legacy ERP - finance, inventory, and procurement - with a custom platform built by 1Solutions. The project was delivered on time and on budget, and we went live with zero disruption to month-end close. Our finance team had full real-time visibility for the first time in years.
Our distribution business had 4 different systems for orders, inventory, finance, and logistics. 1Solutions unified everything into a single ERP with real-time dashboards and EDI connectivity to our top 12 suppliers. Inventory accuracy went from 78% to 98.5% in the first quarter after go-live.
We are a food manufacturing business with complex lot tracking, expiry date management, and food safety compliance requirements. 1Solutions built a custom ERP with full production traceability from raw material to finished goods. Audit prep time dropped from 3 weeks to 2 days.
Why Choose Us for ERP Application Development
15+ years building custom ERP systems across manufacturing, distribution, food and beverage, retail, and professional services - with deep integration expertise, modular delivery, and a track record of replacing SAP and Oracle at a fraction of the cost.
15+ Years ERP & Enterprise Application Expertise
We have been building ERP systems and enterprise business applications since 2008 - across manufacturing, distribution, retail, food and beverage, professional services, and government sectors.
Modular Architecture - Go Live Faster
We build ERP systems module by module. Your core finance and inventory modules go live in 20–28 weeks while manufacturing and HR modules are built in parallel - so your team benefits from the new system long before the full platform is complete.
No Licensing Fees. Ever.
A custom ERP eliminates per-user ERP licensing permanently. For most mid-market businesses, the development investment pays back within 18–24 months versus SAP or Oracle licensing, implementation consultancy, and annual support costs.
Deep Integration Expertise
We have built ERP integrations with 60+ external systems - CRM, eCommerce, 3PL and logistics, banking APIs, EDI trading partners, customs platforms, tax engines (Avalara, Vertex), and BI tools - with full monitoring and alerting.
AI-Powered Demand & Supply Intelligence
We integrate ML-powered demand forecasting, inventory optimisation, supplier risk scoring, predictive maintenance scheduling, and anomaly detection directly into ERP operational workflows - not as a bolt-on afterthought.
SOC 2 Ready, ISO 27001 Aligned
ERP platforms we build include RBAC, AES-256 encryption at rest and in transit, comprehensive audit logs, immutable financial transaction records, data retention policies, and SOC 2 Type II-ready access control frameworks.
US / UK / AU / Global Delivery
We serve manufacturers, distributors, retailers, and service businesses across North America, Europe, and Australia - adapting to GAAP, IFRS, GST, VAT, and regional payroll tax requirements in the ERP financial and compliance modules.
Transparent Delivery. Full Ownership.
Biweekly module demos, weekly progress reports, shared sprint boards, and direct architect access. All source code, data schemas, and IP are 100% yours from day one - no vendor lock-in, no held-hostage upgrades.
