Features

  • Professional invoicing

    Create, send and manage invoices with 11 customizable templates branded with a company logo and colors.

  • Online payment gateways

    Clients pay directly from an invoice in one click through Stripe, PayPal, Square, GoCardless and other gateways.

  • Recurring invoices and auto-billing

    Recurring invoices and automated billing cycles handle repeat clients and keep cash flow predictable.

  • Time tracking and projects

    Projects hold billable time and Kanban boards, and tracked tasks convert into an invoice in one click.

  • Branded client portal

    Each client gets a portal at a company subdomain to view invoices, pay and manage documents.

What users say

Pros

  • Self-hosting keeps invoicing and bookkeeping on a server the business controls for almost no running cost.
  • Setting up ACH from all banks, plus Apple and Google Pay, took surprisingly little effort.
  • Covered mobile app, email sending, three-decimal tax rates and white labelling that alternatives lacked.
  • Updates arrive regularly and install in one click from the dashboard.
  • Custom scripts adjust time rounding and project codes to fit an existing workflow.

Cons

  • The interface feels confusing and unintuitive after years on a simpler invoicing tool.
  • Self-hosted installs break after updates or stop responding a few days after setup.
  • Reverse-proxy setups leave invoice web links unstyled, with buttons that do nothing until a trusted-proxy variable is set.
  • Several hourly rates and flat fees per client need manual setup instead of reusable service presets.
  • The install is heavier than needed, using plenty of server resources and more features than a small shop requires.
