A Ziflow alternative built around a print shop's whole job, not just its proofs.
Ziflow deserves the credit it doesn't often get from competitors: a real free plan, and proofing that reviews far more than print — 1,200-plus file types, colour separation, deep enterprise controls. What it isn't is a print shop's operating system. There's no job board, no quote, no invoice, no client portal — just the proof. Proof System is that too, plus everything around it, still free to start.
The comparison
| Feature | Proof System | Ziflow |
|---|---|---|
| What it actually is | A print shop's job board, quoting, invoicing and proofing, in one place | A creative-review tool — proofing and approval, nothing else |
| Free plan | Yes — 20 active jobs, 5 proofed a month | Yes — 2 users, 2GB storage, 60-day history |
| Starting paid price | $12 / month | $199 / month, billed annually (Standard) |
| Job board, quotes, invoicing | Built in, from Free | Not offered — Ziflow reviews files, it does not run a shop |
| Reviewer needs a login | No — opens from a link | No — public proof links, Free through Pro tiers |
| Review depth (file types, colour separation) | Print-specific: bleed, resolution, cut contour, built in | 1,200+ file types; colour separation on Pro — deeper for teams reviewing every kind of creative |
| White-labelling | From $12 / month | Enterprise only, custom pricing |
| Client portal — customer submits new jobs | Every plan, including Free | Not offered |

Where Ziflow genuinely wins
If the job is reviewing creative broadly — video, web pages, PDFs, any of 1,200-plus file types, not specifically print — Ziflow's depth is real and Proof System doesn't attempt to match it. Colour separation on the Pro tier is a genuine print-production feature most proofing tools skip. And Enterprise brings SSO, SCIM user management, electronic signatures and a fully white-labelled viewer on a custom domain — infrastructure built for a much larger organisation than a print shop typically is.
Why print shops switch anyway
A proof approved in Ziflow is still a job somewhere else — a spreadsheet, a separate system, an invoice typed by hand. Proof System's proof is one step inside the job itself: quote, board, proof, sign-off, invoice, all the same record. That's the difference between a review tool and a print shop's system of record.
And once a shop outgrows the free tiers, the gap widens fast: Ziflow's cheapest paid plan is $199 a month, billed annually, for proofing alone. Proof System's whole ladder tops out at $29 a month, and includes quoting, invoicing and a client portal Ziflow doesn't offer at any price.
The proof, and the job it belongs to, in one place.
