There's no single 'best agency file transfer tool' — there's a stack. A solo designer needs different tools than a 20-person agency with motion designers, account managers, and four concurrent client projects. Most articles ignore this and just list 10 tools without telling you which ones fit which team size.
This guide does it differently. We cover the actual workflow stages (internal storage, team review, client delivery, archive), then recommend the specific stack for solo / small / large agencies with realistic monthly costs. We then review 8 tools in depth — sorted by which workflow layer they actually own.
We built BulkShare in the client delivery layer specifically. We're not trying to replace Dropbox for internal storage, Slack for team communication, or Frame.io for video review. We sit alongside those tools and own the moment work changes hands from your team to the client. We'll be specific about when our layer fits and when other tools win.
