Vlnkovo

Vlnkovo sells yarn and everything around knitting and crochet, online and in its own shop. The new store gives the owners a design that feels like the shop, their data in their own hands, and a till and a website that agree on what’s in stock.

• About 500 products with variants and stock for 1,688 items, imported from the product feed.
• 184 customer accounts, moved without sending anyone an email, plus 161 shop reviews, blog articles and pages.
• 604 redirect rules for 596 old addresses. All 605 tested URLs answer with a 301 to a working page, so search rankings carry over.

• The till is the source of truth.Products and stock come from the Dotykačka POS through webhooks with polling as a safety net. Orders from the web go back to the till, so the shop floor and the website never sell the same skein twice.
• 417 products outside the menu.The import had mapped categories by name and grown a second tree. A one-off script rebuilt the catalogue under the right root; like every migration script it runs as a dry run unless told otherwise.
• Overrides that did nothing on PrestaShop 9.The class index lives in a new place in version 9. Until it’s cleared, the autoloader quietly generates an empty class and the override never runs.
• An honest review badge.The import from the old platform had marked every review as “recommends”, including one-star ones. The badge now appears only when there are real answers, and at least ten of them, which is also what EU rules on reviews expect.
• Ready for e-invoicing in 2027.Invoices are generated in the store with QR payment codes, and Peppol e-invoicing is written and waiting for Slovakia’s 2027 mandate.
