System migration, back office & scanner app · 2026

Kulmine

Kulmine has made washable cloth pads and menstrual products in Osnabrück since 1993. Their Shopware 5 shop, its Pickware warehouse and a fleet of sixty-six plugins had reached the end of the line, while the design was already up to date. So this was a system migration and development project, not a redesign: we moved the whole operation to Shopware 6 with a headless storefront, designed the back office and the scanner together with Amitab Sood, who is responsible for systems at Kulmine, and tuned the front end for modern conversion, search engines and local search.

How it was realised

The project came to us through our label colleague Ankur Sood, whose mother Petra Sood runs Kulmine together with his brother Amitab. The brief was continuity: the same shop the customers know, on technology that will carry it for the next decade. The business case wrote itself: what Kulmine saved on plugin licences financed the migration.

For the customers nothing changed and much improved: the shop, the magazine with its Menszyklopädie, the store finder and the long product guides now live in one place, load fast on a phone and are easier to find on Google and in local search. The design stayed; the paths to the basket got shorter.

Behind the shop, the everyday work got lighter. Set articles are picked as their parts, shipping labels print from the order, payments are matched to invoices as the money arrives, and the bookkeeping goes to the accountant as an export instead of a second system.

The old warehouse scanner would not have survived the move, so we designed its replacement with Amitab Sood at the packing table: Kulmine Scanner, an app for the iPhone that handles picking, packing, labels, goods receipt and stock counts, and keeps working when the warehouse Wi-Fi does not.

The move itself was rehearsed, not improvised: a full trial run a week ahead, three dress rehearsals, then the switch while the old shop kept selling until the last hour. The plan, the decisions and the hours were written down and shared with Kulmine throughout.

What it solved

  • Sixty-six old plugins reviewed one by one and replaced by standard features or our own code, none silently dropped; the licence fees they no longer cost paid for the migration.
  • Pick, pack and ship without the vendor scanner: a replacement designed at the packing table and built as an app of Kulmine's own.
  • Bookkeeping inside the shop: numbered documents, bank reconciliation and the DATEV export, so nothing is typed twice.
  • A front end that keeps its design and gains conversion, search-engine and geo optimisation on the way.
  • Consent done properly: nothing loads before a decision, the decision is logged, and the shop works with everything declined.

The warehouse app

Kulmine Scanner: picking, packing and stock, on an iPhone.

Not a page of the shop but a native iOS app of its own, built for the packing table. It runs on an iPhone 14 in the warehouse, scans the barcodes, talks to the shop over the Admin API and keeps working when the Wi-Fi does not. Every name and address in these screens is made up.

Kulmine Scanner: the packing list of open orders
Kulmine Scanner: an order being picked
Kulmine Scanner: an article with its stock, reserved and free to sell, and a count being booked
Kulmine Scanner: the stock list, searchable by number or name
Kulmine Scanner: incoming deliveries from suppliers
Kulmine Scanner: goods receipt
