Clients, projects, support tickets, invoices, and files — all organized in a single HTML file. No subscriptions, no setup, no scattered apps.
Freelancers and small agencies spend hours every week chasing client info, project statuses, and unpaid invoices — across a dozen different tools.
Contact details in your email, project notes in Notion, contracts in a Drive folder, invoices in a spreadsheet. Every time a client asks a question, you spend 10 minutes hunting for the answer across four apps.
Without a clear view of your billing, you end up chasing payments late, forgetting to follow up, or discovering overdue invoices weeks after the deadline. Cash flow problems start here.
Deadlines, deliverables, support requests, and client communications all compete for your attention at once. Without a central view, something always slips — and it's usually the thing that matters most.
A clean client workspace — every module connected, every piece of information exactly where you need it.
From first contact to final invoice — everything a freelancer or small agency needs to manage clients professionally.
A real-time overview of your entire client business: active projects, open tickets, pending invoices, upcoming deadlines, and key metrics — all in one view.
Store and manage all your client contacts: company name, contact person, email, phone, city, tax ID, and status — searchable and always at hand.
Track every client project with title, linked client, priority, start date, deadline, progress bar, and status — so you always know what's active, on hold, or done.
Log and track support requests, bugs, and feature asks from clients — with ticket number, subject, linked project, type, priority, and status (Open, In Progress, Closed).
