From paper jams to a digital value chain
In real estate and construction, dozens of documents are signed daily. Paper processes slow projects and cause errors.
Physical presence for signatures
Lease and purchase agreements require in-person attendance — a logistical nightmare with investors, tenants and partners at different locations.
Sign anywhere — no in-person requirement
Tenants, buyers and investors sign contracts via a link in the browser — whether abroad, on the construction site or in the office.
Delays from postal delivery
Construction contracts, amendments and acceptance protocols travel by post between developers, planners and contractors. Every day of delay costs money.
Contract closings in hours, not weeks
Construction contracts and amendments are sent digitally and signed the same day. No postal delivery, no waiting.
Document overload in property management
Rent adjustments, utility bills, maintenance reports — property management drowns in paper documents that need signing.
Paperless property management
Rent adjustments, management documents and maintenance reports are signed digitally and automatically archived.
Complexity in construction project management
Construction contracts, subcontractor agreements, plan approvals and acceptance protocols — every project generates hundreds of documents requiring signatures.
Fully digital construction management
From plan approval to construction contract to acceptance protocol — all building documents are signed digitally and traceably.
