Google Sheets inventory & POS without the chaos

Spreadsheets are powerful—until they become your bottleneck. RexInv is built for retailers who want real inventory management and a simple store POS flow.

Manual data entry is error-prone

Typing sales into cells by hand leads to mistakes, lost rows, and corrupted formulas. One typo can throw off your entire stock count.

No real-time visibility

You can't see what sold today without opening the sheet, scrolling, and manually calculating totals. By the time you notice stock is low, it's too late.

Reporting is painful

Building daily profit reports, tracking dues, and generating receipts from a raw spreadsheet takes hours every week. Hours you don't have.

RexInv fixes all of this

Connect your Google Sheet, record sales in one tap, get instant stock updates, auto-generated reports, and real-time analytics — all while your data stays in the sheet you already know.
