I need a professional tech person to update our cloud based epos system

General information for the business: Women's fashion and clothing store Description of requirements/functionality: We sell women's fashion Description of requirements/functionality: We have recently installed an epos till system to our flagship store but we are faced with a few issues with regards stock management and stock imports. We need to find a solution for inputting and or batch importing the many different clothing lines we have. Currently the system will only allow a manual input of mine style, one colour and one size. Many garments we sell come in various colours and varies sizes. At the moment the system is impossible for us to use. The software is cloud based; so looking for someone that can help by installing an app or similar so it can be used for transactions and stock management. Extra notes: Extra notes:
