Who can build custom ecommerce software when Shopify or WooCommerce no longer fits how we sell?
BitIngenuity builds custom ecommerce and retail software for businesses that have outgrown template platforms: headless storefronts, B2B ordering portals with customer-specific pricing, inventory and order management systems, and retail SaaS. We work with DTC brands, wholesalers, distributors, and multi-store retailers — usually shipping a first release in 8 to 14 weeks on Next.js with the commerce backend that fits, whether that is headless Shopify, a custom platform, or both.
Most retailers do not need custom ecommerce software, and we will say so when that is the case: if you sell a few hundred simple products to consumers, a template platform is the right answer and always will be. Custom development earns its cost at the point where the platform starts dictating how you sell — when your B2B customers each have negotiated pricing, when stock lives across three warehouses and two retail stores, when an order needs to split across suppliers, when your configurator has dependency rules no app supports, or when checkout performance is measurably costing you conversions. That is the point where the workaround stack becomes more expensive than the software.
Problems We Solve in Retail & Ecommerce
B2B pricing that no consumer platform models properly
Wholesale and distribution run on customer-specific price lists, volume breaks, contract terms, credit limits, minimum order quantities, and pack sizes. Consumer ecommerce platforms model one price per product, so B2B sellers end up with apps stacked on apps, or with orders still arriving by email and phone and being re-keyed into an ERP. B2B ecommerce development means building the pricing engine properly: per-customer catalogs and pricing, tiered breaks, quote-to-order flows, approval chains, credit checks, and repeat-order tooling that lets a buyer reorder ninety lines in under a minute.
Inventory that disagrees with itself across channels
Sell on a website, a marketplace, a retail counter, and a wholesale channel, and you will oversell — because each channel holds its own idea of stock and reconciliation happens nightly at best. Inventory management software development solves this with a single stock ledger as the source of truth, real-time allocation and reservation, multi-location awareness, and channel sync that pushes availability outward instead of trying to reconcile four systems after the fact. Oversells drop, and staff stop apologizing for orders they cannot fulfil.
Storefront performance quietly costing conversion
Theme-based storefronts accumulate apps, and each app adds scripts. By the time a store has reviews, upsells, chat, analytics, and a personalization widget, the page carries several megabytes of JavaScript and loses mobile shoppers before it renders. A headless storefront on Next.js flips this: server-rendered pages, images optimized and sized correctly, third-party scripts deferred or moved server-side, and Core Web Vitals treated as a budget rather than an aspiration. Faster pages also rank better, which compounds the benefit on product and category SEO.
Order operations that scale by adding people
Manual order routing, returns processed by email, purchase orders raised in a spreadsheet, and shipping labels created one at a time — all workable at fifty orders a day and impossible at five hundred. An order management system automates routing to the right warehouse or supplier, handles splits and backorders, manages returns and exchanges as a first-class flow, and integrates carriers and accounting. The measure is straightforward: orders processed per operations hour, before and after.
Product data trapped in spreadsheets and duplicated per channel
Retailers selling across channels usually maintain product information three or four times: once in the store platform, once in a marketplace feed, once in a print or wholesale catalog, once in a spreadsheet somebody guards. Attributes drift, images differ, translations lag. A product information layer with one enriched record, channel-specific views, and automated feed generation ends the duplication and makes launching a new channel a configuration task instead of a project.

Common Use Cases
Wholesale ordering portal for a distributor
Trade customers log in to their own catalog and pricing, reorder in seconds, and see credit and delivery status — removing hundreds of emailed orders a week from the sales team.
Headless replatform for a growing DTC brand
Keep Shopify for checkout and payments, replace the theme with a Next.js storefront, and recover the conversion lost to a slow, app-heavy front end.
Unified inventory across stores and channels
A multi-store retailer consolidates stock into one ledger with real-time channel sync, ending oversells and enabling ship-from-store and click-and-collect.
Product configurator with real dependency rules
Made-to-order or complex-assembly products configured with validation, live pricing, and a bill of materials passed to production — impossible on template platforms.
Vertical marketplace with curated supply
A niche multi-vendor platform winning on curation and search quality rather than catalog size, with split payments and seller tooling from launch.

How We Work
1. Commerce discovery
We map how you actually sell — channels, pricing rules, stock locations, fulfilment paths, returns — and where the current platform forces a workaround. The output is a scope, an integration list, and a fixed estimate.
2. Platform decision
Headless Shopify, a headless commerce engine, or custom: we recommend based on your pricing complexity, catalog structure, and roadmap, and we say clearly when your existing platform is good enough and the problem is elsewhere.
3. Design and performance budget
Storefront and portal design with an explicit performance budget agreed up front, because in commerce a beautiful page that loads slowly is a net loss.
4. Incremental build, integrations first
Two-week increments on staging, with ERP, payment, and carrier integrations built early since they carry the most risk. You test order flows with real data long before launch.
5. Data migration and cutover
Products, customers, order history, and SEO redirects migrated with verification, then a staged cutover — usually one channel or customer segment first — so traffic and revenue are never bet on a single switch.
6. Optimize on real numbers
Post-launch we work from conversion, search, and operations data: page speed, checkout completion, search relevance, and orders processed per hour. Commerce is a measurement game, so we instrument for it.
Cost & Timelines
Indicative bands based on projects we have delivered. Every engagement is quoted at a fixed price after discovery — you see the number before any code is written.
| Engagement | Typical range | Timeline | What it covers |
|---|---|---|---|
| Commerce audit | $3,500 - $7,000 | 1-2 weeks | Platform, performance, and workflow audit with a written recommendation, integration list, and fixed build estimate. Credited against the build. |
| Headless storefront | $25,000 - $60,000 | 8-12 weeks | A Next.js storefront on your existing commerce backend, with performance budget, technical SEO, and migration of products and redirects. |
| B2B portal or OMS build | $45,000 - $120,000 | 10-20 weeks | A custom B2B ordering portal or inventory and order management system with ERP integration, pricing engine, and operations tooling. |
| Ongoing partnership | From $6,000 / month | Rolling | Continued development, peak-season readiness, integration maintenance, and conversion optimization work. |

Frequently Asked Questions
How much does custom ecommerce development cost?+
A headless Next.js storefront on an existing commerce backend typically runs $25,000 to $60,000 over 8 to 12 weeks. A custom B2B ordering portal or an inventory and order management system with ERP integration generally lands between $45,000 and $120,000. The main cost drivers are pricing-rule complexity and the number of systems you need to integrate — not the number of products, which affects data migration far more than build effort.
Should we move off Shopify or WooCommerce?+
Usually not entirely. The most common outcome we recommend is headless: keep the platform for checkout, payments, and tax compliance — which are expensive and risky to rebuild — and replace the storefront with a Next.js front end you control. Full replatforming makes sense when the pricing model, catalog structure, or fulfilment logic genuinely cannot be expressed in the platform data model, which is far more common in B2B and made-to-order than in standard DTC retail.
What does headless commerce actually give us?+
Three things: speed, because pages are server-rendered and free of accumulated theme apps; control, because the customer experience is no longer constrained by a theme; and SEO, because fast, server-rendered product and category pages with correct structured data compete better in search. The trade-off is that a headless build is real software with real maintenance, so it is worth it when your traffic, catalog, or differentiation justifies it — and not before.
Can you build a B2B portal that connects to our ERP?+
Yes, and it is one of our most common commerce projects. We integrate with NetSuite, SAP, Dynamics, Xero, QuickBooks, and custom or legacy ERPs, syncing customers, price lists, stock, and orders, and writing confirmed orders back so your finance and fulfilment processes stay unchanged. Where an ERP has no usable API, we work with supported export and staged-file patterns and are explicit about the reliability trade-offs involved.
How do you stop us overselling across channels?+
By making one system the stock authority rather than reconciling several afterwards. We build a stock ledger with real-time reservations and multi-location awareness, then push availability out to each channel rather than pulling and merging. Combined with buffer rules for high-velocity lines and near-real-time sync, this removes the great majority of oversells — the residual risk is a genuine timing race on the last unit, which buffers are designed to absorb.
How long does a replatform take, and will we lose SEO?+
A storefront replatform is typically 8 to 12 weeks including migration. SEO loss is avoidable and comes down to discipline: a complete URL map with 301 redirects, preserved metadata and structured data, equivalent or improved page speed, and a staged rollout with rank and traffic monitoring. Done properly, organic performance usually improves after a headless migration because page speed and rendering improve; the failures we see are almost always missing redirect maps.
Can AI meaningfully improve an ecommerce store?+
The applications with clear returns are semantic search that understands intent rather than matching keywords, personalized recommendations driven by behaviour, bulk generation of product descriptions and attributes for large catalogs, demand forecasting to set reorder points, and support agents handling order-status and returns queries. Search is usually first — on large catalogs, poor search is one of the biggest silent conversion leaks.
Do you handle peak-season readiness?+
Yes. For clients with seasonal peaks we run load testing against realistic traffic profiles, review caching and database indexing, set autoscaling and rate limits, rehearse failure modes, and impose a code freeze window with on-call cover through the peak. This is scoped separately from feature work because it needs to happen weeks before the peak, not during it.

Where to Start
Custom ecommerce software is worth building at the point where your platform starts deciding how you sell — customer-specific pricing it cannot express, stock it cannot reconcile, configurations it cannot model, or performance that is costing conversion. Below that line, a template platform plus discipline beats a custom build every time, and we will tell you when that is where you are. If you are past it, tell us how an order actually reaches your warehouse today and we will come back with a recommendation, a scope, and a fixed price.
