Simply Classic Social is a strong AllSeated (Prismm) alternative for event professionals: it includes seating charts and guest management — the core of what AllSeated does — but wraps them in a full business platform AllSeated has no answer for, including a client CRM with proposals, contracts, invoices, and payments, an invitation designer with RSVP tracking, a public vendor directory that generates leads, and a per-profession AI assistant you can run by text and email. AllSeated is the specialist for immersive 3D floorplans; Simply Classic Social is the platform that runs the rest of your business too.

Where Simply Classic Social wins
Where AllSeated (Prismm) fits
AllSeated (Prismm) is the right pick when photoreal, immersive event design is the job to be done — its 2D and 3D floorplans, 10,000-plus object library, tabletop and place-setting designer, and true-to-scale virtual walkthroughs are best-in-class, and its real-time collaboration between planners, venues, and vendors is genuinely excellent. If your day-to-day is designing and pitching layouts for large or complex spaces, AllSeated's diagramming depth is hard to beat.
AllSeated (Prismm) is the specialist you reach for when a room has to be designed in stunning 3D detail — and at that, it is superb. But it stops at the diagram: no CRM, no invoicing, no invitations, no leads. Simply Classic Social gives event pros the seating and guest tools they need and then keeps going — the proposals, the payments, the invitations, the directory, and an AI assistant — so the whole business runs in one place, not just the floorplan.
Frequently asked questions
Does Simply Classic Social replace AllSeated (Prismm)?
For most event pros, yes — it covers the seating charts, guest management, and RSVP tracking that make up the core of AllSeated, inside a platform that also handles your CRM, invoices, invitations, and leads. If your work demands photoreal 3D walkthroughs of large venues, AllSeated's diagramming is still deeper; Simply Classic Social's strength is running the entire business around the event.
Can AllSeated (Prismm) send proposals, contracts, or invoices?
No. AllSeated is a diagramming and guest-list tool and has no financial features — no proposals, contracts, invoices, or payments. Simply Classic Social includes a full client CRM alongside its seating and guest tools, so you can book, bill, and collect payment without a second system.
