Where bigCommerce fits
BigCommerce offers a rare combination: SaaS operating simplicity with genuinely open customisation, native B2B features, and no revenue-based platform fees. That makes it a strong fit for mid-market retail and B2B operations that want platform reliability without template ceilings.
The craft is working within its real constraints: API budgets, Stencil's boundaries, and its update cadence. We build storefronts, apps, and integrations to those standards. For platform selection context, see our eCommerce app development page.

What every engagement includes
Every BigCommerce project ships with the following, agreed in writing before the first sprint begins.
Discovery workshop
A structured workshop maps your goals, users, and constraints into a scoped BigCommerce roadmap with a fixed written quote before any sprint starts.
Named senior team
You get named, senior engineers with CVs you can review, not a rotating bench. The people in the kickoff are the people who ship.
Sprint demos every two weeks
Working builds are demoed live each cycle with CI running on every merge, so progress is visible in software, not slideware.
100% source-code ownership
All BigCommerce source, configurations, designs, and documentation transfer to you on delivery with no licensing strings or vendor lock-in.
60 days of post-launch support
Engineering time is on standby for two months after go-live to triage defects, tune performance, and stabilise the release at no extra cost.
12 months of free updates
Compatibility updates, security patches, and platform upgrades ship free for a full year after handover.
What you can build on bigCommerce
Commerce products our team delivers on the platform.
Custom retail storefront
A Stencil or headless storefront with the UX your brand needs, on BigCommerce's commerce rails.
B2B ordering portal
Company accounts, quote workflows, and ERP-backed pricing using B2B Edition natively.
Private operations app
A control panel app automating your specific merchandising and fulfilment workflows.
Integration-backed store

Migrated store

How a BigCommerce Project Runs
Six stages, each with a sign-off gate before the next begins.
- 01
Discovery
We map your BigCommerce goals, users, and constraints in a structured workshop, ending in a fixed written quote and an architecture risk list.
✓ step 01 complete - 02
Solution design
The BigCommerce architecture, integrations, and delivery plan are designed and reviewed before build work starts, so scaling later is not a rewrite.
✓ step 02 complete - 03
Foundation sprint
Repositories, CI, environments, and a walking skeleton are set up first. Something real runs on a staging URL before feature sprints begin.
✓ step 03 complete - 04
Sprint delivery
Two-week sprints with live demos every cycle. BigCommerce work is reviewed, tested, and merged continuously, so scope surprises surface early.
✓ step 04 complete - 05
Hardening and launch
Performance, security, and accessibility checks run against agreed budgets, followed by a staged BigCommerce launch with monitoring from hour one.
✓ step 05 complete - 06
Support and handover
60 days of included support, 12 months of free updates, and documentation that lets your internal team own the system with confidence.
✓ step 06 complete
The stack behind our bigCommerce builds
Default choices, stated with reasons.
Storefront
Stencil for maintainable theme work; headless on its GraphQL and Checkout APIs where experience requirements justify the build.
APIs
Rate-limit-aware API design with webhook-driven state, because API budgets are a design constraint on any SaaS commerce platform.
B2B
Native B2B Edition capabilities configured first, extended only where your buying process genuinely outgrows them.
Operations
Queue-based integrations, staged deployments, and load testing against peak order volume, treating the store as production software.
How intelligence flows through the store
What each layer reads, and what it changes.
Product discovery
Personalises search and recommendations from behaviour.
Reads
Catalogue, queries, orders
Changes
Ranking and recommendation slots
Inventory intelligence
Watches stock and sync health across channels.
Reads
Inventory levels, sales velocity
Changes
Alerts and sync corrections
Support assistant
Answers order and product questions from store data.
Reads
Orders, help content
Changes
Support replies and tickets
What's included, standard
The baseline on every BigCommerce engagement. Not an upsell tier, just the floor.
Fixed written quote
The price agreed at discovery is the price you pay, with change handled through explicit scope changes rather than silent drift.
Solution architecture document
System design, data flows, and technology decisions written down so your team can audit and own the result.
Dedicated project manager
One accountable point of contact with real authority over the delivery, not a message relay between time zones.
QA on every build
Automated and manual testing on each BigCommerce release candidate, with defects triaged before anything reaches production.
Security review
A checklist-based security pass covering authentication, data handling, and dependency vulnerabilities before launch.
CI/CD and environments
Pipelines, staging, and preview environments configured from week one, so releases are routine rather than dramatic.
Analytics and monitoring
Instrumentation wired before launch so you can see real user behaviour and system health from day one.
Documentation and handover
Code comments, runbooks, and architecture notes written for your next developer rather than for our convenience.
Platform standards review
A review against current BigCommerce requirements and API changes so the build stays current.
