Manufacturing paperwork often combines several field types in one record: text fields for part and lot details, checkboxes for quality gates, signatures for operator review, barcodes for lot or serial lookup, and calculated outputs for yield or defect rate. A generic fillable PDF editor can create boxes, but it usually does not model the workflow behind those boxes.
DullyPDF is a stronger fit when the plant already has fixed PDFs and needs a reusable template layer on top. The source layout stays stable, while the template captures field geometry, names, helper codes, formulas, and export behavior.
