Tallymeter tallymeter.comCan AI replace Tallymeter?
The solo core is a weekend build and nobody should pretend otherwise: a timer, projects with hourly rates, and uninvoiced hours rolled into a numbered PDF. What survives the rebuild is the boring half · two-way Jira worklog sync that reconciles ticket by ticket without double-counting, a hosted MCP server and scoped API tokens your agents can reach from any machine, and invoice numbering plus VAT and bank details that hold up when an accountant reads them. Full disclosure: this entry was submitted by the person who builds Tallymeter. Same rubric as everything else on the list, and the honest answer is that a freelancer billing one client can absolutely one-shot the part they use.
Replacing a paid app means you set it up and keep it running: hosting, updates and backups can be on you. What you give up.
01What it costs
Checked Aug 10, 2026 · source: tallymeter.com.
| Plan | Monthly | Billed yearly | What you get |
|---|---|---|---|
| Pro | $10.38 | $8.65/mo | Unlimited projects and clients; reports, CSV exports, numbered invoices, Jira integration, REST API, and MCP server |
02Could AI build it for you?
The core job: Start and stop a timer against a project, fix entry descriptions after the fact, then roll every uninvoiced hour into a sequentially numbered PDF invoice at the project's rate.
What a working version needs:
- an always-on box if you want the timer off your laptop
- PDF generation
- Jira API credentials if you want worklog sync
- backups you actually test
Submitted by its own builder, judged by the same rubric · the solo core really is a weekend.
03What you'd give up
- two-way Jira Cloud worklog sync that reconciles ticket by ticket
- a hosted MCP server and scoped API tokens agents can call from anywhere, with per-agent attribution
- invoice numbering, VAT and bank details that survive an accountant handoff
- shared team workspaces and per-member unbilled totals
- managed hosting, nightly backups and a phone-sized UI for starting a timer away from your desk
The timer is a weekend. The failure modes are not. Uninvoiced time that silently double-counts against a Jira worklog, an invoice sequence with a gap in it, or a laptop that was asleep when the agent tried to log its hours are all problems you discover on invoice day, in front of a client. A business billing real money for hours generally decides that maintaining the thing that produces its invoices is not the hobby it wants.
