Custom e-commerce and e-shop for ambitious teams.
A shop built to sell, wired into your logistics and accounting tools.
Custom e-commerce is an online store built around your catalogue, payment rails and logistics rather than a generic template. MAWT designs and develops e-shops on the stack matched to your volume, with TWINT, Stripe and Swiss invoicing wired in, so every order flows straight into your ERP and accounting.
Built for Swiss SMBs and growing commercial companies whose online store is a genuine revenue channel: teams losing orders to a clunky checkout, missing local payment methods, or re-keying every sale into their ERP. If you sell online and want it to scale, this is for you.
An e-commerce that converts isn't just a pretty catalogue. It's a smooth checkout, a cart that holds the user, payments that actually go through in your market, and logistics you don't replay by hand on every order.
We build your store on the stack best suited to your volume and catalogue : Shopify when simple and fast, headless (Next.js + Sanity or Shopify headless) when you need premium custom. We wire in your payment rails (TWINT, Stripe, Datatrans, Swiss invoicing), your logistics and your ERP or accounting.
Real case : phaam.ch (e-commerce with optimised catalogue and checkout funnel).
Why most e-commerce stores fail to sell
An e-commerce that converts is not a pretty catalogue. It is a checkout that holds the user, payments that actually clear in your market, and orders that never get replayed by hand.
Most Swiss stores stall on the same friction: a checkout that drops carts, a payment method local buyers expect but cannot find, and an order that lands in three disconnected tools. Each gap quietly leaks revenue you already paid to acquire.
We build the store as a selling system, not a digital brochure. The goal is simple: turn traffic into paid, fulfilled orders without manual rework.
- Abandoned carts from a checkout with too many steps or no trust signals.
- Missing local payment methods (TWINT especially) that buyers expect.
- Orders re-keyed by hand into the ERP, accounting or logistics tools.
- Catalogue and pricing that cannot scale with your range or your seasons.
Our custom e-commerce development approach
We design and build your e-shop on the stack best suited to your catalogue and volume. The work is sequenced so you see a selling store early and refine it on real data, not assumptions.
Custom e-commerce development at MAWT means choosing the right foundation for your business, then wiring it into the tools you already run. We select the stack against three criteria: catalogue size, order volume and how custom the buying experience needs to be. For a focused catalogue we move fast on Shopify. For premium, fully branded experiences we go headless with Next.js and Sanity, or Shopify headless, so design and content stay unconstrained. We connect your payment rails (TWINT, Stripe, Datatrans, Swiss invoicing), your logistics provider and your ERP or accounting through a single order flow, so a sale placed online appears, paid and ready to ship, in the systems your team already uses, with no double entry. Then we tune the checkout funnel on live behaviour: fewer steps, clearer trust signals, recovered carts, and a faster path to payment. You get a store that sells from launch and keeps improving on the levers that move revenue.
Nothing is left as a black box. You keep the codebase, the data and the documentation, so the store stays yours to run and extend.
- Scope the catalogue, volume and markets, then match the stack (Shopify, headless or custom).
- Design the product and checkout experience around how your buyers actually buy.
- Wire payment rails: TWINT, Stripe, Datatrans and Swiss invoicing.
- Integrate logistics, ERP and accounting so orders flow without manual re-entry.
- Set up multilingual and multi currency when your markets need it.
- Optimise the checkout funnel and conversion rate on real user data.
- Launch, measure, and iterate on what moves revenue.
What you get from your e-shop
Every store ships as a clean, owned codebase you control, not a rented template you outgrow. You leave with a shop that sells and a team that can run it without calling us for every change.
Cart recovery runs in the background: when a buyer drops out before paying, the store captures the email at checkout and triggers a timed reminder sequence that brings a measurable share of those carts back to payment. The ERP and accounting sync works the same way day to day: the moment an order is paid, it lands in your back office as a clean record with the customer, the line items, the VAT and the shipping address already mapped to your fields, ready for fulfilment and the books. Your team stops copying orders between tabs and starts shipping.
The outcome is a store that does the heavy lifting: it converts, it gets paid, and it fulfils, with the operational plumbing already connected. Stock levels, pricing and seasonal ranges stay in sync across the catalogue and your ERP, so what a buyer sees online matches what you can actually deliver.
- A conversion-focused store on a stack matched to your volume.
- Swiss payments that clear: TWINT, Stripe, Datatrans and invoicing.
- Live ERP, accounting and logistics integration, no order re-keying.
- An optimised checkout funnel with automated cart recovery built in.
- Multilingual and multi currency support when your markets require it.
- Clear analytics so you can see what sells and where buyers drop.
Who custom e-commerce is for
This is for Swiss SMBs and growing commercial companies whose store is a real revenue channel, not a side experiment. If you are losing orders to a clunky checkout, missing TWINT, or re-keying every sale into your ERP, a custom build pays for itself.
It fits teams who have outgrown a template and feel the friction daily: stock that drifts out of sync, a catalogue that buckles when the range grows, and a checkout you cannot change without fighting a theme. A custom build removes those ceilings and gives operations room to scale.
