We've grown over the years and now our home-grown warehousing and logistics solution is not sufficient. Something like TradeGecko looks perfect, but it's only available in English. We have multiple warehouses and need to pull pick lists for smaller orders from our packing room as well as full-carton orders for our warehouse for larger orders (frequently a mix in each order from our online shop). Currently everything is done manually. After scanning the goods, the order is uploaded to our accounting system to generate packing list and invoice.
We use opencart for our website, and are planning to stick with that. For our accounting back-end we use a small Czech program. We're happy to change if there is something we can localize or is already available in Czech.
