Custom retail software for omnichannel, B2B, and multi-store operations.

Shopify Plus and RetailPro handle the standard retail use case well. The limits become apparent when your business has requirements that fall outside their assumptions. B2B pricing is the most common: Shopify's price lists handle simple tier pricing, but customer-specific negotiated rates by SKU, volume-weighted averages, and contract price overrides require middleware or workarounds that are brittle and hard to maintain. Multi-location inventory is another: Shopify's multi-location inventory is adequate for simple store-and-ship models, but if you have complex fulfillment rules, a separate warehouse management system, or a franchise model where each location manages its own replenishment, the platform's inventory model becomes a constraint. ERP integration is a third: both platforms offer integration apps, but integration quality varies significantly, and the data model between a retail platform and an ERP is rarely a clean mapping. Custom software encodes your specific pricing rules, inventory logic, and ERP data model directly. There is no middleware layer to maintain, no workaround to document, and no per-transaction fee at scale. We will tell you honestly whether custom is justified for your specific requirements.

An order management system (OMS) is the layer between your sales channels and your fulfillment operations. It receives orders from every channel (ecommerce, in-store POS, phone, EDI from wholesale buyers), applies your fulfillment routing rules (which warehouse or store fulfills which order based on stock availability, proximity, and shipping cost), tracks the order through picking, packing, and dispatch, and updates the customer and the originating channel with status. A retailer needs a custom OMS when the off-the-shelf routing rules in Shopify or their 3PL's WMS do not match their actual fulfillment logic. If you have multiple warehouses with different stock profiles, if you fulfill from stores for local orders, if you have wholesale and retail orders with different SLAs, or if you have a returns process that requires manual grading and stock decision, a custom OMS encodes those rules and executes them consistently at order volume. We scope OMS projects with your operations manager and your warehouse team to capture every routing rule and exception before the design phase.

B2B pricing in retail is often more complex than the standard tier model. A wholesale distributor may have: base price lists by product category, volume breaks by order quantity or order value, customer-specific contract prices that override the list price for named SKUs, promotional pricing that applies only during a date range, and currency pricing for international accounts. Standard SaaS retail platforms handle the simple case: two or three price tiers. They do not handle customer-specific SKU-level overrides cleanly, and they do not handle the rule priority logic that determines which price applies when multiple rules are true simultaneously. Custom pricing engines encode the priority logic explicitly: contract price beats volume break beats tier price beats list price. The rules are documented, version-controlled, and auditable. A pricing audit can reconstruct exactly which rule produced the price on any historical order. We scope the pricing model during discovery with your commercial team, because the logic is always specific to the business and must be documented correctly before the build.

Yes. Legacy ERP and WMS integration is a common requirement in retail software projects. Integration approach depends on what your ERP or WMS exposes: SAP S/4HANA and SAP ECC integration via RFC, BAPI, or OData; Oracle EBS and Oracle ERP Cloud via REST or SOAP APIs; Microsoft Dynamics 365 via OData REST API; AS400 and IBM iSeries systems via ODBC, direct database reads, or file-based EDI exchange; Manhattan WMS and Blue Yonder WMS via their REST APIs or flat-file EDI interfaces. The integration scope covers the data flows that matter: stock level synchronization between the retail platform and the ERP (so the OMS routes based on live stock), purchase order status updates from the ERP to the supplier portal, and sales order and invoice posting from the retail platform back to the ERP. We assess integration feasibility during discovery with your IT team present. Legacy systems sometimes have limited API access, and we design around those constraints rather than discovering them mid-project.

A custom order management system for a mid-size omnichannel retailer typically runs $50,000--$85,000. A B2B pricing platform with customer-specific rates, volume tiers, and a self-serve buyer portal runs $45,000--$80,000. A custom POS system with ERP integration and multi-store support runs $40,000--$70,000. A supplier portal with PO management, delivery tracking, and performance reporting runs $35,000--$60,000. A full omnichannel platform combining OMS, POS, inventory management, and supplier portal runs $100,000--$160,000. These ranges depend on the number of ERP and channel integrations, the complexity of the pricing rules, and whether mobile apps are required alongside the web platform. Every project is fixed price, agreed before development starts.

A focused single-scope project, a supplier portal or a pricing platform, typically runs 10-14 weeks. An OMS or custom POS with ERP integration runs 12-16 weeks. A full omnichannel platform runs 16-22 weeks depending on the number of channels and integrations. Discovery is one week: we map your inventory flows, pricing rules, and integration points before any code is written. You get a fixed-price proposal at the end of week 1. Working software is demonstrated at bi-weekly sprint demos throughout the project. The final phase covers parallel testing with live orders before the full cutover. No development starts without your sign-off on the scope document.
