    I need my current inventory reviewed and recalibrated so that stock moves faster without creating service gaps. The focus is squarely on inventory management, specifically stock level optimization, with the primary success metric being a measurable improvement in stock-turnover rate. Here’s what the assignment involves: • Analyse recent SKU-level demand, lead times, and safety stock assumptions. • Calculate and recommend optimal reorder points / min-max levels that accelerate turnover yet still guard against stockouts. • Produce a clear implementation roadmap I can plug straight into our existing ERP or spreadsheet workflow, including any formulas, dashboards, or report templates you build. Please base all recommendations on easily auditable logic—if a ...

    I need our raw financial numbers transformed into clear, interactive Power BI reports that management can rely on for day-to-day decisions. The datasets live in SQL Server plus a few recurring Excel exports; once connected, they must be modelled, cleaned, and enriched with the right DAX measures before being published to Power BI Service and shared through workspaces. What matters most to me is your experience: show me a brief overview of similar finance or accounting projects you’ve handled, the size or complexity of the data involved, and any notable outcomes you helped your client achieve. Screenshots or live demo links are welcome if you can share them. Deliverables I expect: • Robust data model with refresh schedules configured • A suite of role-based reports (P&...

    I have an existing dataset already living inside Power BI and I now need a clean, interactive dashboard that turns those numbers into meaningful financial insights for my team members. The goal is to give them a single page (with drill-through detail where it makes sense) that tracks revenue, expenses, cash flow, variance against budget, and any other standard finance KPIs you normally see.
