Custom All-in-One E-commerce Solution

Most stores are not one system. The website runs on one platform, the till on another, the invoicing in a third program and the stock in an ERP updated by a nightly export. Somebody reconciles the difference by hand, and every one of those seams is a place where stock sells twice, a receipt goes missing or the same sale is typed in twice.

Enormous effort goes into the storefront — the photography, the copy, the collection pages — and then the customer is handed to a checkout nobody art directed, on a subdomain in a different typeface, that asks for an account before it asks for a card.

A custom all-in-one e-commerce solution starts from those two problems, not from a theme. The storefront is the part people see; the checkout, the receipts and the integrations are the part that decides whether the year was profitable.

The checkout

As few steps as the payment actually requires, on your own domain, in your own type. Guest checkout by default, saved details for the people who want them, and no page that asks the same question twice.

Payments

Cards, wallets, bank transfer and instalment providers where the market rewards them, with SCA and 3-D Secure handled properly rather than bolted on.

Integrations

ERP, warehouse, accounting, CRM and shipping connected two-way and in real time — so the number on the product page is the number in the building.

Merchandising

Bundles, tiered pricing, B2B price lists and campaign logic your team runs itself, without a developer in the loop for every promotion.

Online and in store

Sales at the counter go through the same dashboard as the online orders, with the same catalogue, the same stock and a receipt issued on its own.

Every store we build runs on NEXTCOMMERCE, the headless commerce platform we write and maintain ourselves. The storefront is drawn for one brand alone in React and Next.js; underneath it, the engine — catalogue, stock, checkout, orders and integrations — is written in Node.js and PostgreSQL and shared by every store on it.

That split is the point. Custom e-commerce written once for one merchant is correct on launch day and then decays: a payment provider changes an API, a security advisory lands on a Friday, and four years later the merchant pays for the same store twice. On NEXTCOMMERCE the engine is patched and improved continuously, and every fix lands for every store at once.

Headless, API-first

The storefront, the dashboard and the mobile app are clients of one API, so a new channel is a new client rather than a new platform.

A real-time dashboard

Orders, stock, customers and revenue as they happen, not as they were at last night's export.

A native mobile app

The store in the App Store and Google Play, on the same catalogue, the same prices and the same accounts as the website.

Most platforms treat the Greek requirements as somebody else's problem — ten apps from ten vendors, each a subscription, each an upgrade that can land in your checkout on a Tuesday. In NEXTCOMMERCE they are core features: myDATA and invoicing, instalments, cash on delivery, courier integrations and marketplace feeds, maintained by the same team that maintains the engine.

For e-commerce development in Greece, that is the difference between a store that is legal and complete on launch day and one that is assembled from plugins and kept alive by a retainer.

Most merchants run the website on one platform, the till on another and the invoicing in a third program, and someone types the same sale in twice at the end of the day. In NEXTCOMMERCE the e-shop, the receipts, myDATA and the POS in the physical store are one system, with one catalogue, one stock count and one list of orders.

Receipts, issued automatically

Every paid order issues its own receipt or invoice: on card payment, on dispatch for cash on delivery, and a credit note on its own when an order is cancelled. No second program and no retyping.

Sent to myDATA

Each document goes to AADE through a certified e-invoicing provider, and the MARK comes back in seconds, stored on the order next to the payment.

Card payments in the store

A sale at the counter is a new order in the same dashboard. The amount goes to the POS terminal, the card is tapped, the receipt is printed, and the sale sits next to the online orders.

One view of the business

Online and in-store sales, receipts, invoices and credit notes in one place, searchable by number, MARK, customer or VAT number.

The storefront, the design, the content and the data are yours outright. The NEXTCOMMERCE engine is licensed as software as a service: we host it, run it, patch it and back it up. Leaving takes one month's written notice and comes with a complete export — the terms are written down in plain language rather than described in a meeting.

The architecture assumes the catalogue grows and the traffic spikes. Caching and rendering are decided per route, the search is built for the size of the catalogue you will have rather than the one you have now, and a peak day is a capacity question rather than an emergency.

And we will tell you when you are not there yet. Below roughly a quarter of a million euros a year, with a small catalogue, no ERP and one courier, a rented platform usually wins the arithmetic — a custom all-in-one solution pays off when the store has become an operation rather than a website that takes orders.
