Competitor facts are from their published pages and third-party listings, last checked September 10, 2026; most quote privately and prices change. ProjectFlowLive figures are the published Solo price and the free allowance in force on that date. A grey dashed mark means the vendor does not state the rule publicly.

What a seat costs per year

ProjectFlowLive against the role-matched flagship pair — a markup seat plus a field app. The role rows are per person, per year on both sides. The four-person row is one team price for all four on ours against four separate per-person prices on theirs.

How to read the four-person row: the ProjectFlowLive figure is one Starter Team price that covers all four seats for a year (monthly × 12). The flagship figure is four people each paying their own per-person price for a year.
