Service 07 — Online shop & marketplace

Selling online — with an order that also stands up legally.

A shop and a marketplace are the same thing with one difference: in a shop you sell your own goods, on a marketplace you sell other people's. Cart, checkout, price display and the return policy are the same stretch of road either way — and that is where a click either becomes a contract or becomes an argument. Which of the two you need is the first thing we settle; more often than not it is the shop, even when the word used in the meeting was „platform“.

Who it's forFor retailers and manufacturers who want to sell their own goods — and for businesses that bring other people's supply and demand together and earn from it.

Starting point

Where it usually goes wrong

The order button says the wrong thing

„Continue“, „Complete“, „Submit“: a neutral word at the last step hides what the click actually does. The button has to say exactly what happens — „Place order“ — with the full total beside it: items, shipping and tax, no figure appearing later. A total that only turns up on the card statement is where a sale turns into a chargeback and a complaint.

The real price only appears at the checkout

Shipping revealed in the second-to-last step, tax as a footnote, no unit price per kilo or liter on goods sold by quantity. That is both the most common reason people abandon a basket and a breach of the price-display rules most markets have — so it costs you twice.

Returns are not one single rule

Perishable goods, items made to the customer's specification, sealed goods once opened: for part of any range returns cannot be taken back at all. A shop that treats everything alike either accepts returns it never meant to accept or refuses ones it promised.

Demonstration

A basket turns into a contract

The path from the product to the confirmation — with the four points that decide whether the order holds.

01
The product with its complete price
Total including tax, shipping, and — for goods sold by quantity — the unit price per kilo or liter. All of it at the product, not at the till.
02
The basket finishes the sum
Lines, shipping, total. What stands here also stands on the invoice; after this step no further amount appears.
03
„Place order“ — with the total beside it
The full summary directly above the button, and the amount that will be charged — items, shipping, tax — right next to it. This is the point at which the customer is committing money, so it is the point at which the figure has to be complete.
04
Confirmation, receipt and return policy
In writing without delay, with the return form and a note on which exclusion applies to this product.

Scope

What you get

First the question: your own shop, or a marketplace: If you sell your own goods, a shop is faster and cheaper. It only becomes a marketplace once third parties list, price and get paid themselves — with everything that hangs off that. What we do NOT take on: your warehouse, shipping and returns stay with you, we are not a payment institution, and the legal texts come from your attorney. What we build is a shop in which those texts actually bite.
A checkout built the way the law requires: The full order summary immediately above the button, the total including shipping and tax right next to it, and a written confirmation without delay afterwards. That sequence is not a design preference — it is what stops an order becoming an argument.
Prices that are complete before anyone clicks: Total price including tax, shipping shown on the product rather than at the till, and for goods sold by quantity the unit price per kilo, liter or meter right beside it. Where you discount, the lowest price of the preceding 30 days as the reference.
Returns, exclusions included: The return policy in plain words, a printable return form and a returns path your team can actually operate. Which exclusion applies is recorded per product group — perishables, made to order, opened seal — and the customer learns it at the product, not afterwards.
Taking payment without holding card data: The payment provider takes the money; your server never sees a card number. Strong customer authentication, reversal on cancellation and refunds are part of the flow rather than something added later.
On a marketplace: who sells, who is liable, who holds the money: Every listing states whether a business or a private individual is selling — buyers need it, because whether there is any warranty or return at all depends on it. Who the contracting party is appears before the purchase, not in the small print. On request an escrow account holds the money until the goods have arrived.
Ranking and reviews you can check: Fair-trading rules increasingly require the main parameters behind the order of results to be disclosed, and require you to say whether reviews are checked for authenticity — and how. Both sit next to the list as readable text. Paid placement is labeled as such, or there is none.
Connected to your inventory and accounting: Stock, prices and documents flow to the systems you already work in. A shop whose stock somebody retypes in the evening will eventually sell goods that are gone.

Process

How it runs

01
Settle the range and the roles
What is sold, by whom, to whom. That decides whether it becomes a shop or a marketplace — and which return exclusions can arise at all.
02
Scope & fixed price
Checkout, payment methods, shipping rules, interfaces. Then a binding proposal with a fixed date.
03
Build & place real test orders
You order, cancel, return and refund yourself — on the payment provider's test account, before any customer pays a cent.
04
Launch & handover
Switchover, a walkthrough for taking orders and handling returns, documentation. Afterwards the code, the accounts and the credentials are yours.

Questions

What gets asked about this most

What does a website cost with you?

We quote fixed prices, not hourly rates. After the call you get a proposal with one number and one date — what's in it, stands. Starting prices per package are on the pricing page. If something new comes up mid-project, we discuss it first rather than quietly adding it to the invoice.

How long does a project take?

A company website typically runs three to five weeks, an app six to ten weeks plus the store review, a single automated workflow one to two weeks, an AI agent two to four weeks. The biggest variable isn't on our side — it's how quickly copy, images and access credentials arrive. The proposal states exactly what we need from you and when.

I already have a website. Does everything need rebuilding?

Not necessarily. In the call we look at what exists. Sometimes fixing load time, accessibility and the inquiry flow is enough — considerably cheaper than a rebuild. If a rebuild genuinely is the better answer, we'll tell you why.

What happens after launch?

Your choice. Either you take over — code, content and all credentials are fully yours, with no dependency on us. Or you take the retainer: updates, monitoring, security patches and ongoing development at a fixed monthly price, cancellable monthly. No annual contract, no notice period.
