Excel Program for Food & Beverage Inventory

I need help with my google sheets program designed for comprehensive food and beverage inventory data management. The tool is to facilitate complex data import/export, edits and organization, specifically using a completed CSV file to import to my POS Software "Lightspeed" I've included the current draft and am stuck on "Pairing" #Keys in Sheet: #Keys_Bev & Inv to their corresponding Inventory items in Export_Master, pulled into Sheet #Keys_Bev & Inve, both of which have their own separate sku and item details.

Key requirements include:
- High skill level of Excel or Google Sheets data pulling/organizing across multiple sheets
- Basic understanding of inventory data and relevance with food & Beverage

Ideal skills and experience:
- Advanced Excel proficiency
- Experience with CSV data manipulation
- Strong organizational skills
- Background in food and beverage industry is a plus
