Approval Studio
SMBOnline proofing tool for designers, agencies, and brands to review creative work.
Workflow-linked proof versions keep approvals and comment context aligned across each revision cycle.
Approval Studio is a proofing workflow tool built around document review sessions where teams can comment directly on uploaded PDFs, keep reviewer threads organized, and move work through defined approval states. The workflow model supports repeatable runs for each revision, so teams can compare what changed across proof versions and keep feedback attributable to specific reviewers. Audit trail retention is geared toward review accountability by recording workflow actions linked to proof iterations.
A tradeoff appears when file formats go beyond PDFs, since the strongest markup and interchange experience is centered on PDF proofing rather than rich DOCX and PPTX round-tripping. Approval Studio fits best when editorial teams need consistent redline feedback and status movement across multiple reviewers with clear ownership on each revision.
