In their words
invoices were getting lost, payment statuses were unclear, and there was no central source of truth for job-level financials
AP by it's nature is anything but vanilla - so there were many exceptions to manage at any point during the process.
Our company is currently evaluating potential solutions for AP Automation (high volume- 2,000 ish bills a month)

AP and finance teams
Where they talk
- r/Accounting
- r/Netsuite
- r/smallbusiness
- r/Entrepreneurs
- r/CFO
- r/growmybusiness
- r/xero
- r/procurement
Tools they use today
- NetSuite
- QuickBooks
- Excel
- Claude
- Xero
- Ramp
- SAP
- Melio
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
