app.webhill.net: SaaS for Clients, Invoices and Website Monitoring

About the project

app.webhill.net is our own product: a multi-user web panel for freelancers and small agencies that replaces spreadsheets, reminders and a dozen separate services. Users sign up with an email address and see only their own data. There are no paid plans or limits.
Platform sections on the landing page

Sections

  • Dashboard: unpaid invoices, upcoming payments, websites that are down and recent notifications
  • Clients: client records with statuses (active, paused, archived), contacts and notes
  • Invoices: one-time, monthly and quarterly. Recurring invoices are created automatically, with due-date reminders
  • Tasks: statuses, priorities, deadlines, cost and a link to a client
  • Services: hosting, domains and subscriptions, with reminders before each charge
  • Monitoring: HTTP response and SSL certificate checks for websites every 4 hours
  • Backups: automatic backups of VPS projects over SSH/SFTP, with archive verification
  • Finance: income and expenses linked to clients, invoices, tasks and services, with a balance and a breakdown by category

  • The landing page is managed from the CMS and updates without a redeploy
