Our Ecommerce Development Process

No long consulting cycles or confusing handoffs. We keep things simple: a clear process, honest timelines, and a team that stays with you from first call to post-launch growth.
01

Discovery Call

We understand your business, current setup, and blockers to recommend what you actually need.
02

Audit & Scoping

We review your systems and data and provide a fixed-price roadmap upfront.
03

Build & Integrate

We build in sprints with regular updates, keeping you informed at every stage.
04

Grow Together

We stay on after launch with same-time-zone support and ongoing improvements.

Industries We Serve

Different industries sell in fundamentally different ways. Our eCommerce solutions account for those buying cycles, pricing models, and operational workflows that make each business unique.

Manufacturers

Distributors

Wholesalers

Growing B2B Businesses

Manufacturers

Turn complex part configurations and custom specs into structured digital orders with interactive catalogs and direct-quote workflows.

Distributors

Keep large, multi-location SKU lines moving accurately with live inventory sync and high-speed bulk reorder tools.

Wholesalers

Protect negotiated contract pricing and payment terms while giving approved accounts private self-service ordering portals.

Growing B2B Businesses

Scale digital sales across new products, customers, and channels without rebuilding the commerce experience every time the business grows.

Challenges Holding Your Digital Commerce Back

You didn’t choose your eCommerce stack. It accumulated. Each tool or workaround solved a need at the time, but over the years, those fixes became part of how you sell online.

Weak Product Discovery

Buyers struggle to find the right SKUs or technical parts across large, complex catalogs.

Rigid Platform Limits

Standard platforms and off-the-shelf templates break under complex B2B workflows and custom business logic.

No Buyer Self-Service

Customers still depend on sales reps for basic reorders, invoice copies, and account tracking.

Siloed Contract Pricing

Managing custom account rates and negotiated terms manually leads to pricing errors and checkout friction.

Slow Quote-to-Order Cycles

Custom configurations and price approvals get stuck in email threads instead of converting directly into orders.

Disconnected Operations

Storefront data remains isolated from the central ERP, WMS, and inventory systems, forcing manual data re-entry.

Frequently Asked Questions

Still have a question about how Ecommerce Website Development works with your business? Talk to our team directly.
How much does it cost to build an eCommerce website in St. Louis?
Most custom eCommerce projects cost $10,000–$25,000. Complex builds with ERP integrations, custom checkout rules, or enterprise workflows can range from $30,000 to $75,000+. We define the scope and requirements upfront, so you know what the project will cost before development begins.
We build with security and PCI-DSS requirements in mind from the start. This includes secure API endpoints, token authentication, SSL encryption, role-based permissions, and compliant payment gateways. Payment data stays within the payment provider rather than being stored directly on your site.
Most eCommerce projects take 6–16 weeks. The timeline depends on your platform, integrations, catalog size, custom functionality, and business workflows. Smaller storefronts can launch sooner, while ERP integrations and complex B2B requirements typically take longer.
We structure product data around your catalog and how customers search for products. Custom fields and metaobjects can handle technical specifications, downloadable documents, fitment data, and cross-reference part numbers while keeping filtering and product discovery fast.
Yes. One store can support both. Retail customers see standard pricing and checkout options, while approved wholesale buyers can access custom pricing, catalogs, bulk ordering, and net payment terms using the same inventory.
We configure checkout around your B2B requirements. This can include PO number validation, credit limits, invoice-based payment terms, multi-user accounts, and approval workflows for corporate buyers.
We map old URLs to their new destinations, set up 301 redirects, and preserve important metadata and structured data. This helps protect existing rankings and organic traffic when the new store goes live.
Orders can be routed based on warehouse stock, customer location, shipping rules, and fulfillment requirements. This lets the store choose the right warehouse, distribution center, or dropship location for each order.
We keep development and testing separate from your live store. Migrations and the final cutover are planned around your operations, with testing completed before launch to minimize downtime and prevent lost orders.
We continue supporting the store after launch by monitoring integrations, ERP syncs, API activity, server performance, and order workflows. If an issue appears as real customer traffic comes in, we can quickly identify and resolve it.
