A tour of Engager
From the first enquiry to the signed letter and the finished job. Pick a stage to see how it works.
A branded prospect form on your website creates a deal card the moment someone enquires. Price the work with the pricing tool, send the proposal and see when it is opened.
Choose the services, fees and responsibilities and the letter is built from your templates. The client signs online, the portal is ready and the job is created.
Break services into tasks and job phases, assign them to your team and track progress on a Kanban board. Checklists keep the detail consistent and automations send the reminders.
Automated emails go out when a deadline is near or records are overdue. Send a bulk message to every affected client in one go, and see the replies against the client with Microsoft 365 and Gmail synced.

Reviews
4.6 out of 5 from 199 reviews on Trustpilot, 181 of them five stars.
“Moved over from another practice management system and I’m so pleased I did. My only complaint is why I didn’t do it sooner!”
“Finally found a practice management software that ticks every box and keeps us on track with deadlines, jobs, onboarding and billing.”
“It keeps everything in one place, and has taken a lot of admin stress off our plate. It was built by an accountant for accountants, and you can really tell.”
