Put AI to Work on Your Invoices

We don’t think TallyHo needs AI built in. But we fully believe you should be free to use it if you want to.

The AI Data Feed is for people who like automating their workflows. Generate a secret URL, share it with Claude, ChatGPT, Gemini, or any LLM, and let it generate invoices, timesheets, and reports from your live data.

What It Is

In Settings > Integrations, click Generate URL. You get a secret URL unique to your account and unguessable by anyone else.

Share that URL with any AI tool or automation script and it will fetch your time tracking data directly. No login, no OAuth, no account creation needed. You can paste it straight into your browser to see exactly what gets returned.

You can regenerate it at any time (which invalidates the old one) or revoke it entirely. The endpoint is read-only, so someone with the URL can see your data but cannot edit, delete, or access your account.

Using It with an AI Tool

We’ve built in an _instructions block that tells the AI how to interpret your data and calculate figures correctly, so you don’t need to explain your data structure in every prompt. That said, AI isn’t always great at maths, so double-check totals before sending anything to a client.

Example Prompts

Generate a timesheet:

“Using the time tracking data from this URL, create a timesheet for [Client Name] since [date]. Group by project, list each task with description and hours, then show a total.”

Create a professional invoice:

“Generate a professional invoice from this time tracking data URL. Include: date, client name, itemised list of work with hours and rates, subtotals by project, and a grand total.”

Summary for a client:

“Summarise the work done for [Client Name] in [Month/Year] using this time tracking data. How many hours were logged? What were the main project areas? What’s the total billable amount?”

Prepare a monthly report:

“Create a monthly billing report from this time tracking data. Show total hours and revenue by client, identify the highest-value projects, and list any unbilled work.”

Export for accounting software:

“Convert the time tracking data from this URL into CSV format suitable for importing into [Xero/FreshBooks/Wave]. Include columns for: date, description, hours, rate, amount, and client.”

Works with Claude, ChatGPT, Gemini, Copilot, OpenClaw, or any LLM that can fetch a URL.

What It Isn’t

The AI Data Feed is read-only. Your AI tool can read and reason over your data, but it cannot create, edit, or delete anything in TallyHo. It won’t be able to mark tasks as invoiced. It is also not an MCP server, so it won’t appear as a connected tool inside Claude or similar apps. It is simply a URL that returns your data as JSON, which any AI tool or script can fetch.

I’d genuinely love to hear how you’re using this. Drop me a line at [email protected] with your prompts, workflows, or any suggestions.
