CUSTOM APPSBigCommerce App Development

BigCommerce App Development for Your Unique Business Needs

When no marketplace app does exactly what you need, we build it.

We build custom BigCommerce apps, API integrations and admin tools for merchants, and public apps for agencies and founders. We check what BigCommerce and existing apps already do first, and build only what is missing.

For store owners

Which part of your business doesn’t fit BigCommerce as it comes?

Most merchants come to us with one of the same few problems. An app that already exists, a custom app or an integration can often close the gap.

Systems that don’t talk to each other

Orders, stock and customer records are re-entered between BigCommerce, your ERP, accounting or supplier systems.

Bulk work done by hand

Someone edits prices, categories, coupons or stock one by one, or fixes a spreadsheet import every week.

Shoppers can’t find products

Search and filtering that don’t match how your customers look for things, and no way to see what they searched for and didn’t find.

A rule only your business has

Special pricing, order routing, approvals or product data that BigCommerce and the marketplace don’t cover.

An app that no longer fits

An app you rely on is slow, broken, out of date or does almost, but not quite, what you need.

An idea for your own app

You want to turn an internal tool or a new idea into a BigCommerce app, for one store or for the marketplace.

Our own BigCommerce apps

Start with an app we have already built

We build and maintain apps of our own for BigCommerce. If one of them does the job, you can install it today. If it nearly does, we can tell you what a custom version would take.

What we build for BigCommerce stores

Choose one focused app or a broader project. We confirm the available APIs, data and access before agreeing a scope.

Custom BigCommerce apps

  • Control panel tools for products, orders and customers
  • Custom data, settings and business rules
  • Built on the BigCommerce APIs and webhooks
  • Installed on your store, or on all the stores you run

You get: A scoped app for your store, with the agreed features documented and tested.

BigCommerce API integration

  • ERP, accounting, PIM and supplier systems
  • Inventory, shipping and fulfillment systems
  • One-way or two-way sync, where the other system allows it
  • Retries, logging and error alerts

You get: Mapped data flows with a clear owner for every error and exception.

Bulk tools & automation

  • Alerts when something fails

You get: A tool your team can use daily instead of a weekly spreadsheet job.

Storefront apps & widgets

  • Search, filtering and merchandising
  • Pop-ups, banners, product add-ons and checkout helpers
  • Scripts that load on the storefront without editing your theme code, where the setup allows
  • Tested on your theme and plan

Existing app improvements

  • Review of an app you already use
  • Troubleshooting, fixes and performance work

You get: An app built for many merchants. See the section for agencies and founders below.

How BigCommerce apps work

Choose the right type of app for the job

BigCommerce has a few ways to build and release an app. We recommend one based on who will use it and how it needs to be installed.
Recommended

Single-click app

Installed from the store control panel and authorized with OAuth, so the merchant never handles API keys.

  • Opens inside the BigCommerce control panel
  • Right for most custom and marketplace apps
  • Works for one store or many
Simple jobs

Connector app

A lighter build that uses API account credentials created in the store, with no install flow.

  • Good for one store and a single task
  • The merchant enters and keeps the credentials
  • Quicker to build, narrower in reach
Who can install it

Draft, unlisted or public

A draft app is for testing. An approved app can stay unlisted or be published on the App Marketplace.

  • Draft apps are registered but never submitted
  • Public apps are reviewed by BigCommerce
  • We can’t guarantee approval or timing

What marketplace apps must do. BigCommerce requires that listed apps support multiple users, serve every callback over HTTPS, store tokens against the store and not an email address, and return a branded, non-empty control panel page. Apps that handle card data also need a PCI compliance review. We build to the published approval requirements.

Our approach

Use the right tool for the job.

A custom build isn’t always the answer. We look at what already exists before we recommend one.
First choice

Use what BigCommerce already offers

Native features, or an app from the marketplace, including ours, when it does the job.

  • No custom build assumed
  • Lower cost and upkeep
  • Your team stays on familiar tools
When there’s a gap

Build the missing piece

A focused custom app, integration or automation, scoped to the gap.

  • Access and feasibility checked first
  • Maintenance agreed up front
  • Documented for handover
Always

Keep people in control

Clear rules for what runs on its own and what needs approval.

  • Prices, refunds and customer messages need sign-off unless agreed
  • Checks for missing data and failures
  • A simple way to pause or roll back
Example projects

See what a BigCommerce app project could look like

Three common starting points. Each one shows what goes in, what happens, what comes out and who decides.
Supplier sync

A supplier stock and cost feed

Starts with
A supplier file or API with stock and cost data
What the app does
Matches supplier items to your products and updates inventory on a schedule
Output
Updated stock levels and a list of unmatched items
Human review
Your team decides what to do with unmatched or out-of-range items
ERP link

Orders sent to your ERP

Starts with
New paid BigCommerce orders, picked up through webhooks
What the app does
Sends order data to the ERP and writes back status and tracking details
Output
Orders in both systems, with failed sends flagged
Human review
A named person resolves flagged orders
Bulk tool

A bulk price and promotion tool

Starts with
A CSV file of products, prices or promotion rules
What the app does
Checks the file, shows a preview and applies the changes in batches
Output
Updated catalog or promotions, plus a log of every change
Human review
You approve the preview before anything is saved

Illustrative examples, not client projects. Feasibility, data availability and effort are confirmed for each store.

BigCommerce API integration

Connect BigCommerce to the systems you already run

We work with the BigCommerce APIs and webhooks and with the other system’s API, file exports or connector, depending on what each side supports.

Suppliers & inventory

Stock, cost and product feeds, purchase workflows and multi-location inventory.

ERP & accounting

Orders, customers, invoices and payouts between BigCommerce and your back-office systems.

CRM & marketing

Customer, order and segment data sent to the tools your sales and marketing teams use.

Shipping & fulfillment

Labels, tracking and fulfillment status with carriers, 3PLs and warehouse systems.

What we confirm before we quote: which systems are involved, what data moves and in which direction, how often, and what API access you have. Not every system offers the same options, and some BigCommerce capabilities depend on your plan.

For agencies and app founders

Bring your BigCommerce app idea to life.

Whether you’re building for a client or for your own product, we help with the technical side so you can focus on the business.

Agencies: client projects

  • Custom apps and integrations for your clients’ stores
  • White-label development under your brand
  • Specs reviewed with your team before work starts
  • Scope, ownership and hosting agreed per client

Good for: agencies that need extra development capacity without a full-time hire.

Founders: marketplace apps

  • Product planning and technical architecture
  • Merchant onboarding and billing
  • Preparation and submission for the BigCommerce App Marketplace
  • Maintenance and updates after launch

Good for: founders building one app for many merchants.

About marketplace approval. BigCommerce reviews every app submitted for the marketplace and makes the final decision. We build to its published requirements, but we can’t guarantee approval or timing.

Hire BigCommerce developers

Hire a BigCommerce developer for a project, or for ongoing work

Start with a defined project, or work with a dedicated BigCommerce developer who learns your store and your team.
Defined project

A scoped build

A fixed brief, such as one app or one integration, with agreed deliverables.

  • Written scope and acceptance criteria
  • Testing and handover included
  • Good when the specs are clear
Dedicated support

A dedicated BigCommerce developer

Hire a dedicated BigCommerce developer for continuing work on your store or your client stores.

  • One developer who knows your setup
  • A backlog you prioritize
  • Good for steady improvement work
After launch

Ongoing maintenance

Fixes, updates and small changes once a project is live.

  • Monitoring and bug fixes
  • Updates for BigCommerce changes
  • Retainer arrangements

How engagement works. The model, team size and any commitments are agreed in your proposal after we review the work.

Ownership & support

You choose who owns and hosts the app

There’s no single arrangement. We agree the one that suits your budget and plans, and it affects the cost.
Option 1

Full ownership transfer

We hand over the code and the rights. You, or your team, host and run the app.

  • Code and rights transferred to you
  • You host on your own hosting
  • Cost reflects the transfer
Option 2

We host the finished app

We keep the code, host the finished app and keep it running for you.

  • You use the app, we run it
  • A hosting fee after the project is complete
  • Cost structure differs from a transfer
For agencies

White-label development

We build behind your brand for your clients, on the ownership terms you need.

  • Your brand stays in front of your client
  • Ownership and hosting set per project
  • Partnership terms agreed up front

Support after launch

Projects usually include 30 days of free support, and we may extend that on larger projects. After that, an optional retainer covers fixes, updates and changes. The exact terms are in your proposal.

How it works

From idea to a working app

The first conversation is about fit. Technical feasibility is confirmed before we quote.

Web commerce pros created a really lovely design for our website. They also changed the layout for our images and updated/resized images so that the site is overall much more attractive. We have been receiving a lot of positive feedback from customers on the ease of use and the overall look of our site. In addition, we are very grateful to Roy for coming up with a creative solution for allowing customers to easily create their own quotes, which has been very helpful to both our operations and our customers.

Design & custom features

Webecommercepros are great web developers and good people. They moved our 1,000+ page website from our old platform to BigCommerce and did it fast and efficiently. They created all of our new artwork, 301 redirects, converted all of our products and more in record time at a very reasonable cost. We use them for all of our ongoing work like increasing load speed, updating our theme and shopping cart and site changes that we ask for. Highly recommend!

Dealing with Roy and Web Ecommerce Pros was a fantastic experience. They migrated our website to another platform and everything is great. Roy really paid attention to all my requests and on transition day, he made sure everyone on his team was available in case something went wrong. I would highly recommend this company and will use them for future projects.

FAQ

Before you start a BigCommerce app project

Plain answers about apps, integrations, ownership and cost.

App development

It means building software that connects to a BigCommerce store through its APIs and webhooks. An app can add a feature to the control panel or the storefront, move data between BigCommerce and other systems, or automate work your team does by hand.

Often an existing app or a native BigCommerce feature does the job, and we say so. We check those first, including our own apps, and recommend a custom build only when there’s a clear gap.

A single-click app is installed from the store control panel and authorized with OAuth, so the merchant doesn’t handle API keys. A connector app uses API account credentials created in the store and has no install flow. Single-click apps are the type BigCommerce recommends.

Yes. We help with planning, onboarding, billing, submission and maintenance. BigCommerce reviews every app submitted for the marketplace and decides on approval, so we can’t guarantee it or promise a date.

Yes, we offer white-label development for agencies. Ownership, hosting and communication with your client are agreed for each project.
