About Stairkey Stairkey is an end-to-end business software platform designed for service businesses, with particular depth for contractors and real estate professionals. It integrates customer relationship management (CRM), estimating, invoicing, payments, and accounting into a single workspace. The platform operates on a capped price model, meaning users pay a fixed rate rather than per user or per transaction. Stairkey is accessible on mobile devices, allowing users to quote, schedule, and invoice from the field. The workflow is structured around five core steps: capture the lead, quote the work, schedule it, invoice and get paid, and see the business. Each lead or deal is stored on a single record, eliminating the need to switch between separate applications for quoting, scheduling, and invoicing. The quoting process supports plain line items or a formula driven takeoff builder that automatically calculates quantities from room dimensions. Scheduling allows users to drop jobs or visits onto a calendar and check crew availability. Completed work converts into invoices with payment status tracked alongside the job. The business overview section provides reports and optional double entry accounting that are linked to the work records. Key features include a client CRM with portals for approvals, files, and status; recurring job scheduling; estimates and invoices as simple line items; a takeoff builder for formula based quantities; change orders; offer tracking and accepted offer views; contact history with notes, tasks, and reminders; and a deal pipeline showing stage, offers, and critical dates. The platform is intended for use by contractors, real estate agents, and other service businesses that need to manage the full lifecycle from initial enquiry to final payment within one connected record.
