Retail & E-commerce Software Experts
SaaS platform development, modernization, and long-term stewardship for multi-brand retailers, DTC merchants, and the commerce platforms that serve them.
PALADEM designs platforms across storefront and catalog, order management, point of sale, inventory and replenishment, and customer data and loyalty. Our retail software experts treat order, inventory, and customer as shared entities across channels, so a sale rung at a register, placed online, or captured by a service agent moves through the same ledger, the same inventory positions, and the same customer record. We build unified omnichannel commerce platforms for the long horizon: seven to ten years of seasonal peaks, catalog growth, new channels, and compounding customer data.
Sub-sectors We Have Worked Across
Each sub-sector carries its own workflow conventions, data model, and integration landscape. Our experience spans the set below, which lets us reuse proven platform primitives while respecting the details that differ from storefront to back office to store floor.
Storefront & Catalog
Headless and traditional storefronts, product catalog management, merchandising rules, and category and search experiences. We model SKUs, variants, bundles, and promotions as first-class entities so merchandisers can evolve the catalog without engineering intervention for every new product type.
Order Management (OMS)
Order orchestration across channels, sources, and fulfillment locations: capture, validation, allocation, routing, and settlement. We design the OMS so every order carries a clear lifecycle and a clear source of truth, which keeps returns, exchanges, and partial fulfillment from fragmenting across systems.
Point of Sale (POS)
In-store point of sale running on fixed terminals and mobile devices: scanning, pricing, tender, returns, and line-busting. We build POS as a client on top of the same order and customer model as the web, so store associates, managers, and reporting all see a single reality of the business.
Inventory & Replenishment
Inventory positions by location, in-transit visibility, safety stock, and replenishment planning. We design the inventory model around atomic position updates and channel-aware available-to-promise so the storefront, POS, and OMS share the same answer to "can this ship today."
Customer Data & Loyalty
Unified customer profiles, preference and consent state, loyalty ledgers, and marketing-ready segmentation. We design the customer record so it carries household, order history, returns, and loyalty status as related facets of one identity rather than five disconnected feeds.
Our Retail & E-commerce Software Services
Custom Retail SaaS Development
We design and build storefront, OMS, POS, and customer data SaaS platforms end to end, from initial architecture through production deployment. Our engagements target the long-lived core of the platform: the catalog, order, inventory, and customer layers the business depends on for a decade or more.
Legacy Platform Modernization
Retail platforms rarely tolerate a big-bang rewrite. We use incremental modernization to stabilize the existing system, carve the surface area into bounded modules, and migrate module by module behind feature flags. Storefronts keep selling and stores keep ringing while the platform moves forward.
Integration Architecture
Retail platforms live inside an ecosystem of ERPs, tax engines, payment processors, 3PLs, carriers, marketing clouds, and review and loyalty providers. We design the integration layer so each external system can be swapped or extended without rewriting catalog, order, or customer business logic.
Compliance-Aware Data Design
PCI DSS on payment flows, CCPA and GDPR on customer data, and jurisdictional sales tax across the catalog: the compliance landscape is real. We design the data model, access controls, and audit trail to carry compliance obligations by default, which keeps the platform defensible as regulations evolve.
Platform Stewardship & Support
We offer long-term stewardship for production retail platforms: dependency upgrades, security patching, performance tuning, peak-season readiness, incident response, and feature work. Our stewardship engagements are sized to the real surface area of your codebase rather than a fixed retainer that drifts out of alignment with reality.
Run Your Retail & E-commerce Business on PALADEM Platforms
When a retailer or multi-channel merchant needs working software now rather than a full custom build, we offer three productized platforms under the PALADEM brand that cover the full loop: customer acquisition, store and e-commerce operations, and unified payment acceptance.
PALADEM Grow for Customer Acquisition, Loyalty & Email Marketing
PALADEM Grow covers storefront and e-commerce lead capture, abandoned-cart and browse-abandonment automation, email and SMS broadcasts, loyalty and referral sequences, review capture, and AI voice agents for store and order-status calls. The platform is pre-wired for high-volume consumer marketing motions.
PALADEM Scale for POS, Inventory, Accounting & E-commerce Operations
Our customizable ERP platform gives multi-channel retailers a single integrated system for in-store point-of-sale, multi-location inventory, purchasing, accounting, e-commerce storefront, warehouse and fulfillment, HR, and supplier collaboration. We configure the Scale platform to the retailer's real workflows rather than splitting operations across an unconnected POS, accounting tool, and e-commerce cart.
PALADEM Collect for Unified Online, In-Store & Mobile Payments
Our unified payment processing and gateway platform gives retailers a single consolidated payment surface across online checkout, in-store POS, mobile and line-busting acceptance, subscription and recurring billing, and hosted payment pages for marketing funnels. Fees are consolidated, PCI scope is contained through hosted fields, and refund and dispute workflows are unified rather than split across merchant accounts.
Custom Software When Productized Platforms Fall Short
Productized platforms cover common retail patterns well, but merchants often carry headless-commerce architectures, custom integrations to Shopify, Square, or BigCommerce, specialty B2B storefronts, or marketplace and drop-ship workflows that fall outside those patterns. When that happens, we build custom software from the ground up under our Software Stewardship Framework™ so the custom work is a long-lived asset rather than a one-time script.
Why PALADEM?
- Built for Retail’s Long Horizon. Storefronts, POS, and order platforms run every day of the year across every channel, and catalog and customer data compound in value over time. We design for that horizon, not for the launch demo.
- US-Based Architecture, Global Delivery. Senior US architects lead every engagement, supported by a global engineering team for efficient, cost-effective delivery. See our full services for how we structure engagements.
- Software Stewardship Approach. Every engagement is guided by our Software Stewardship Framework™, which treats your platform as a long-lived asset to be cared for across all eight stewardship pillars rather than a one-time deliverable.

Learn moreFrequently Asked Questions
What kinds of retail and e-commerce platforms has PALADEM built software for?
PALADEM has built SaaS platforms across storefront and catalog, order management, point of sale, inventory and replenishment, and customer data and loyalty. The shared thread is omnichannel retail software used every day by merchandisers, store associates, and customers. Our platforms are designed to treat order, inventory, and customer data as shared entities across channels.
How do you handle PCI DSS and customer-data privacy (CCPA, GDPR)?
Payment and privacy obligations are designed into the architecture from day one. We rely on processor tokenization so primary account numbers never land in application storage, segment cardholder data environments to keep scope tight, and design the data model around privacy-by-design and consent lifecycle: opt-in state, data subject access, retention, and deletion are first-class concerns rather than afterthoughts. This work falls under our Security Stewardship and Business Stewardship pillars.
Do you integrate with ERPs, tax engines, and fulfillment providers?
Yes. Retail platforms rarely live in isolation. Our integrations typically include ERP systems for financial and inventory master data, sales-tax engines such as Avalara and TaxJar for jurisdictional tax calculation, and 3PL and carrier APIs for fulfillment, shipping rates, and tracking. We design the integration layer as a normalized boundary so each external system can be swapped or extended without rewriting order or catalog business logic.
Can you modernize a legacy retail platform without disrupting sales?
Yes. Retail platforms typically cannot tolerate a big-bang cutover because sales flow every hour of every day. We use incremental modernization: we stabilize what is fragile, carve the surface into bounded modules, and migrate channel by channel behind feature flags so we can move storefront, POS, or OMS while the others keep operating. The platform stays shippable throughout, consistent with our Engineering Stewardship pillar.
Can you unify POS, e-commerce, and customer data into a single platform?
Yes. We treat inventory, order, and customer as shared core entities with channel-specific experiences layered on top. That means a sale rung at a register, placed on the storefront, or captured by a customer service agent writes to the same order ledger and the same customer record, so reporting, loyalty, returns, and fulfillment behave consistently regardless of which channel initiated the transaction.
