Hour Cap vs solidtime
solidtime is a modern open-source time tracker with a clean UI and API-first design. Hour Cap is a managed SaaS built to push invoices to Xero. Here's how they compare for Xero users.

No accounting integration at all
solidtime can generate PDF invoices on paid plans, but those invoices live entirely within solidtime. There is no connection to Xero, QuickBooks, or any other accounting software. To get invoiced time into Xero, you would need to manually recreate each invoice.
Hour Cap creates invoices directly in Xero. Contacts sync automatically, line items are grouped however you need, and tracking categories cascade from project to client to org. The invoice lands in Xero ready to send.
Billing features built for agencies
solidtime focuses on time tracking and basic invoicing. There are no retainers, no timesheet approval workflows, and no activity logging. These features are essential for agencies and teams that bill clients on recurring agreements.
Hour Cap includes dedicated retainer management with configurable billing periods, approval workflows with manager sign-off, and a full activity log so you can see who changed what and when.
- Retainers with real-time progress bars and alert thresholds
- Timesheet approvals that prevent unapproved time from being invoiced
- Activity log with full audit trail
When solidtime might be a better fit
We believe in being transparent. solidtime does things Hour Cap doesn't.
Open source and self-hosted
solidtime is open source (AGPL-3.0) and can be self-hosted via Docker. You get full control over your data and infrastructure with the ability to audit and modify the code.
Cross-platform apps
solidtime offers a desktop app for macOS, Windows, and Linux, browser extensions for Chrome and Firefox, and a command palette for keyboard-driven workflows.
Data import from other tools
solidtime can import existing data from Toggl, Clockify, and CSV files, making it easier to switch from another time tracker without losing historical data.
