Calisto Sign is a standalone e-signature platform built on CalistoOS and the Microsoft cloud. It gives property managers, hotel operators, real estate agents and teams, brokerages, and growing companies a calm, branded signing experience that keeps documents, signers, and properties in one place.
Use Calisto Sign as your primary e-signature solution or drop it into the systems you already run. When you are ready, connect it to Calisto Deals for full transaction timelines, to Calisto Ops for post-signature tasks and work orders, and to Calisto Navigator for a branded signing room your clients will actually enjoy using.
Calisto Sign replaces generic envelopes with structured signing rooms. Each room holds the documents, signers, roles, and timelines for a specific deal, mandate, stay, vendor agreement, or internal approval, with an audit trail that stands up to scrutiny.
Group documents, signers, roles, and status in one clean workspace. No more lost links or mystery envelopes.
Turn your repeat paperwork into templates that take minutes to launch, not hours to prepare.
Define the order of signatures and approvals so complex transactions move forward without back-and-forth.
Calisto Sign is flexible enough to run any e-signature workflow, but it shines where people, properties, and portfolios are central to the business.
Collect signatures for management contracts, rental mandates, onboarding packs, and renewals without losing track of which property or portfolio each agreement belongs to. Perfect for second homes, vacation rentals, and community management.
Use Sign for corporate rate agreements, group reservations, brand and franchise documentation, and vendor contracts, all tied back to the properties and portfolios that matter to your leadership team.
Run listing agreements, buyer mandates, offers, addenda, and closing packages through a signing experience designed for property deals. Works perfectly with your existing CRM—and builds an even stronger picture when combined with Calisto Deals.
Use Calisto Sign for hiring documents, vendor contracts, NDAs, and internal approvals. Keep everything on the Microsoft cloud alongside the rest of your data and systems.
Calisto Sign is designed so your team can build repeatable flows once and reuse them across markets, offices, and portfolios. Every step is structured, tracked, and auditable.
Upload your document, add signature and data fields, and save it as a reusable template. Map key fields such as names, addresses, prices, property IDs, and dates so you never key them in twice.
Add signers and viewers, assign roles, and define the order of signatures and approvals. Use presets for common patterns such as buyer/seller, owner/tenant, or hotel/vendor.
Send branded invites with a single click. Signers access a clean, mobile-friendly signing page where they can review, fill, and sign documents without downloading anything.
Watch who has opened, started, or completed their part. Trigger automatic reminders, or nudge specific signers manually when a deal or onboarding is time sensitive.
Completed documents are stored with a full audit trail and certificate of completion. When you use Calisto Deals or Calisto Ops, signatures can automatically trigger status changes, tasks, work orders, and onboarding steps across your portfolio.
Calisto Sign works on its own as your primary e-signature platform. When you are ready to connect more of your business, it plugs directly into Calisto Deals, Calisto Ops, Navigator, and the rest of the CalistoOS stack.
When paired with Calisto Deals, every signing room connects to a specific deal. Agents and PM teams see offers, addenda, and final contracts alongside pipeline value, commissions, and partner splits—no double-entry, no missing paperwork.
With Calisto Ops, signed documents trigger tasks, tickets, and work orders automatically. New management mandates open onboarding checklists; rental agreements create stay and operations workflows; vendor contracts create compliance and renewal reminders.
Use Navigator to give buyers, sellers, owners, tenants, and vendors a single place to see what they still need to sign, where they are in the process, and which documents are already complete.
Connect Sign with Assure and Calisto 24·7 so quality inspections, incident logs, and signed agreements all share the same property history. When something goes wrong, you have photos, timelines, and signatures in a single chain of evidence.
Calisto Sign covers the essentials—secure signatures, audit trails, and document storage—but adds the property context and operations hooks that generic tools lack.
Tie every signing room to the right property, portfolio, office, or deal. When someone asks “Which contract covers this unit?” you have the answer in seconds.
Every action—invites, opens, signature events, and IP/timestamp logs—is captured in a clear audit trail and certificate while clients see a simple, beautiful signing flow under your brand.
Standardize documents across offices and markets while leaving room for local variations. Update a template once and put the change to work on the next hundred agreements.
Use Calisto Sign on its own today, then layer in Power Automate flows, Calisto Deals, and Calisto Ops when you are ready for end-to-end automation from document to operations.
Calisto Sign is billed per seat with generous usage, so you can use it as your primary e-signature solution for sales, management, rentals, and internal documents—without worrying about envelope counts. Start with a single team and grow to an entire brokerage, hotel group, or management company.
