Online stores

Selling that doesn't stop at the cart.

A store isn't a template with payments bolted on — it's stock, returns, invoices, and what happens when two people buy the last item in the same second. We approach a store like any other system whose data has to add up, because that's exactly where stores break.

In short

We build custom online stores when the selling doesn't stop at the cart: stock, returns, invoices, couriers and accounting all have to line up. PB Devs in Poznań, Poland treats a store as a system whose data must add up, because that is exactly where stores break. If an off-the-shelf platform is enough for you, we'll say so and turn the work down.

What it covers

  • A store wired into what your business actually runs on: stock, accounting, couriers.
  • Payments and their edges — failed transactions, refunds, subscriptions.
  • Performance under real traffic, not with three demo products.
  • Honestly: if an off-the-shelf platform is enough for you, we'll say so and turn the work down.

Where to check it

The questions that come up

If you sell a few dozen products, ship by courier and have no unusual rules — take Shopify or WooCommerce. It will be cheaper and faster, and we'll tell you so rather than issue an invoice. A custom store starts to make sense once there's a warehouse an off-the-shelf platform doesn't understand, your own pricing logic, or an integration nobody planned for.
