  • r/Netsuite
  • r/smallbusiness
  • r/Entrepreneurs
  • r/CFO
  • r/growmybusiness
  • r/xero
  • r/procurement

Tools they use today

Why those fall short

  • software accepts bad entries without blocking or flagging them
  • Nobody checks the SOP folder; they just ask for a quick answer
  • invoice preview fails, payment dates revert, searchbar removed
  • no item-master setup, illegible handwriting, totalling mistakes, no packing tracking
  • systems not integrated, so same data entered twice per payment
