Pricing · priced on the value, not the hour

Pick your size. Then pick whose name is on it.

Same software. Same monthly. Two ways to have it — and three sizes. Every price is a starting point we tailor to you.

License · run it as Buttress OS

The monthly, nothing down — start this week. On screen the system is Buttress OS; everything it sends out — invoices, statements, schedules, your client portal — carries your business’s name. Leave whenever: your data exports and comes with you.

White-label · make it yours

your logo, your colors, your name across every screen, your own web address, on the same monthly. White-label is quoted per project rather than posted — talk to us and we price it with you.

In every tier — including the smallest

Contacts & CRM · Calendar (subscribes to your phone) · Records (your filing system & source of truth) · Connect (team chat + 1:1 and group video, plus guest links — the same native video layer that runs ESPOsocial, so no Zoom and no third-party meeting service) · Command Center with live charts · Approval Desk · Owner’s Manual · works on your phone

You never pay extra for a contact list or a calendar. Tiers differ by how big you run it — seats, locations, how many departments are switched on, and how deep the AI org goes.

Studio

$550/mo

Questions, answered straight

What you’re probably wondering.

Do I own the software?

No, and that is deliberate. You licence it, the way you licence every other tool you run on. What you own outright is your content, your data and your brand — exportable any time, including the day you leave. We build, host, maintain and keep improving the software for a flat monthly, so you are never left maintaining it yourself.

Are there per-seat or per-transaction fees?

No per-transaction fee — you connect your own payment processor and keep 100% of your revenue. Seats are unlimited on every tier — it never costs more when you hire somebody.

Is it really built for architecture?

Yes. The Buttress OS is configured to how architecture actually works — not a generic template. We tailor it to your business before it goes live.

How long does it take to launch?

Most builds go live within a few weeks. We start with the smallest version that works on your real data, prove it, then expand — so you see something real early.

Can I move off my current software?

Yes. Data migration starts at $1,500 and we bring your existing records over, so you are not starting from a blank slate.

Do you offer non-profit pricing?

Yes — 30% off monthly for mission-driven organizations, plus founder (20% off for life + 50% off white-label) and annual-prepay (2 months free) programs.
