Why It Matters

1099 Compliance Is Still Manual and Risky

From collecting contractor data to filing forms and handling errors, 1099 workflows are fragmented, time-consuming, and prone to compliance issues.

Manual data collection leads to errors and delays

W-9 collection, validation, and tracking are often handled through emails and spreadsheets.

Filing at scale is operationally complex

Managing hundreds or thousands of contractors across entities increases risk of missed deadlines and incorrect filings.

Lack of validation increases penalties and rejections

Incorrect TIN/name combinations result in IRS penalties and rework.
