Custom e-commerce software built for real order volume, not a demo cart
Off-the-shelf platforms are fast to start but rarely fit a store with real complexity. We build the parts that need to be exact.
Bitsbuffer builds storefront, checkout, inventory, and fulfillment systems scoped around how your store actually sells, not a generic template. Stock levels sync across every channel in real time, so a traffic spike does not turn into an oversold product or a support queue.
What we build for e-commerce
Storefront & checkout
Storefronts, checkout, and fulfillment systems designed to hold up under real order volume, not a demo cart.
Inventory & fulfillment
Stock levels synced across every sales channel in real time, so nothing sells out on the site while it is still sitting in the warehouse.
Payments & reconciliation
Gateway integrations and settlement reports that match what landed in the bank, not what the dashboard estimates.
Accounts & loyalty
Customer accounts, saved carts, and loyalty points that stay accurate across web, app, and in-store, so a reward earned in one channel works in every other one.
Returns & support
Return and refund workflows tied to inventory and payments, so a processed refund updates stock and the ledger at the same time, not three separate tickets later.
How we approach it
We have shipped production ecommerce builds: storefronts, custom checkouts, integrated payment gateways, and inventory logic tied to fulfilment. We walk through shipped work relevant to your build in discovery, scoped to what your store actually needs.

Seven out of ten carts leave empty industry-wide. That number alone will not tell you what to build. Here is how to read the real breakdown before you touch your checkout.
Multi-Channel Inventory Sync: Where Off-the-Shelf Tools Break
Inventory distortion cost global retailers $1.77 trillion in 2025. Most of that never shows up as a line item. Here is what actually causes it and what to fix first.
Questions about e-commerce builds
Both, depending on what the business actually needs. Some teams need a fully custom storefront and checkout; others need custom inventory or fulfillment logic layered onto a platform they already run. We scope this in discovery, not before.
Stock levels sync across every channel in real time, so a traffic spike doesn't oversell what's actually in the warehouse. This is one of the five things we build for every e-commerce project, see the scenarios above.
Yes. Gateway integration and settlement reporting that matches what actually lands in the bank is standard scope, not an add-on.
Shopify and Magento are the right call for most standard stores, they launch fast and do not need a developer for everyday changes. Custom stops being optional once inventory, fulfillment, or checkout logic has to match how the business actually operates, not a template's assumptions. Discovery is where we tell you honestly which one you need.
Yes. Migration is scoped like any other build: what data moves (products, orders, customer accounts), what integrations get rebuilt versus kept, and a cutover plan that does not take the store offline mid-migration.
