# How We Build a Web Shop from SKUs to First Order

We start a web shop with how money and parcels move, not with a theme that dies on the first discount. SKU count and checkout rules freeze before the palette.

How we build a web shop starts with money and parcels, not with a theme demo that dies on the first discount. If we cannot say how a guest pays, how a box leaves, and who changes a price on Tuesday, we are not ready to draw a grid.

CodeLoop Studio runs that process from Sarajevo. The product page is [ecommerce website development](https://www.codeloop.ba/ecommerce-website-development). The definition of the product — shop versus brochure — is [what a web shop must do](https://www.codeloop.ba/blog/web-shop). This note is the sequence we actually freeze.

## Week one is rules, not a palette

We write down how you take money today: cards, cash on delivery, bank transfer, pickup at the door. Then courier zones and cut-offs. Then where stock lives — a spreadsheet, a warehouse tool, or a person. If that is fuzzy, a beautiful catalogue still sells the wrong thing.

SKU count is the other freeze. Twenty products with honest photos is a different build from two thousand variants and an ERP that “has an API” with no documentation. We will not promise a weekend launch for the second case. A marketing site is a different contract: [website development](https://www.codeloop.ba/website-development).

## What we lock before anyone designs

* **Checkout on a phone.** Delivery cost before pay. A guest who cannot finish on one screen is not a “mobile tweak” in week eight. It is the brief.
* **Admin the owner keeps.** Price, stock, sold-out hide, and a basic order list without a ticket to us. If only we can change a SKU, you do not own a shop.
* **Accounts in your name.** Domain, hosting, payments, Search Console. We do not hold the store hostage in a studio login.
* **Integrations only with a real feed.** A warehouse spreadsheet is an import, not magic. Custom software around the cart — B2B login, ERP — is [custom software development](https://www.codeloop.ba/custom-software-development), scoped so the shop is not a hostage list.

## What “done” means on handover day

Done is a guest who can finish checkout, an owner who can update the catalogue, and a first real order you can point at. Category URLs get titles and Search Console when those pages need to rank — not a plugin flipped on at the end, and not a #1 guarantee.

We demo weekly. You see the cart on a phone, not a slide of “e-commerce best practices.” If the brief moves, the estimate moves in writing. Silence for three months is not how we run a shop.

## A shop we can show, without invented GMV

[DigitalPlay](https://www.codeloop.ba/study-case/digitalplay) is the catalogue, payment, and admin we can walk through. Markets that change checkout — cash on delivery in Serbia, EU cards and Croatian invoices — are separate articles: [Belgrade](https://www.codeloop.ba/blog/web-shop-beograd) and [Zagreb](https://www.codeloop.ba/blog/web-shop-zagreb).

Send how you take money today and a rough SKU count. We reply within **24 hours** via the [online estimate](https://www.codeloop.ba/online-estimate) or [contact](https://www.codeloop.ba/contact). Studio in Sarajevo. No fake warehouse in the footer.
