Retail Order Management Services
OMS Implementation & Integration Services for Retailers
Implement a new order management system, migrate from a legacy platform or connect the OMS you already run. Nextuple helps retailers, grocers and distributors turn complex requirements into working order and fulfillment flows, from solution design and integration through testing and go-live.
An OMS Implementation Built Around Your Operations
Your OMS has to support how you sell, promise, fulfill and manage exceptions. We translate those requirements into platform configuration, integrations and a rollout plan shaped around your channels, fulfillment network and existing systems. Still defining requirements, choosing a platform, or deciding on your target architecture? Explore our OMS strategy and consulting services.
OMS Implementation & Integration Services
Launch a new OMS, connect your existing platform or modernize the systems behind your order operations. From platform configuration and system integration to upgrades and testing, Nextuple delivers the technical work needed to put your OMS into operation.
OMS Implementation
Configure your selected OMS around order capture, sourcing, fulfillment, returns, and customer service. Translate approved requirements into platform configuration and extensions, with testing and rollout support from our delivery team.
OMS Integration
Connect your OMS with commerce, ERP, WMS, POS, payments, and fulfillment partners. Build and validate the integrations that keep orders, inventory, shipments, and transaction data moving across your retail environment.
Migration & Cutover
Coordinate data and open-order migration, integration changes, and cutover rehearsals around your launch plan. Confirm readiness with business and technology teams, then support order processing and issue resolution through agreed post-launch stabilization.
OMS Upgrades
Upgrade your OMS with a plan for existing customizations, integrations, and operational dependencies. Use dry runs, regression testing, and a phased cutover to validate the release and reduce disruption to daily operations.
QA & Test Automation
Test order flows across your OMS and connected systems, including cancellations, split shipments, returns, and fulfillment exceptions. Build automated regression coverage and support end-to-end and user acceptance testing before release.
Performance Engineering
Test OMS response times, throughput, and integrations against expected trading volumes and peak demand. Identify bottlenecks, tune affected components, and retest against agreed performance criteria before launch to verify readiness.
OMS Integration Across Your Retail Technology Environment
Nextuple delivers end-to-end order and inventory management system integration of best-in-class OMS platforms into your ecosystem. Using pre-built connectors, accelerators, and reusable integrations from our Integration Hub, we connect OMS with ERP, WMS, payments, shipping, POS/returns, and last-mile—so you launch faster, reduce risk, and scale confidently. Deploy anywhere with our cloud partners: we implement and modernize the OMS you run, whether on-prem, hybrid, or cloud.
