What people Google and ask on Reddit
Preparers often have one official fillable 1099-NEC and a QuickBooks or Excel export with payer names, TINs, and box amounts. Copy-pasting into forty PDFs is error-prone; mail merge in Acrobat is clunky. Search intent is almost always “same PDF, many rows.”
Workflow with Autofiller
Export a UTF-8 CSV with one row per payee. Upload the CSV and your blank 1099-NEC PDF, map each field to a column once, then generate the ZIP. Spot-check two random PDFs against source data before e-filing or mailing—Autofiller does not replace your review procedures.
When to choose something else
If your software already e-files 1099s end-to-end, stay in that lane. Use this path when you only have a flat file and a PDF template, or when a client insists on a specific fillable PDF layout.
