Track open invoices and prepare accurate customer reminder drafts with an AI invoice follow-up agent. It uses the role criteria, source files and approval rules you choose, then saves the filled output in a named Google Drive folder. This keeps the workflow repeatable without handing your judgment to the agent.
Track open customer invoices and prepare accurate reminder drafts. The agent keeps the steps, checks and output consistent, while you keep every decision.
Picture tomorrow's handoff.

Use the Receivables Follow Up Agent with your assistant
The same three files run on any assistant that reads plain text. Pick yours for the step-by-step setup - where the files go, what a run looks like, and the honest limits:
- Instinct - hand the three files to Instinct in chat - it keeps them across sessions, so the agent becomes a standing workflow you trigger with one line.
- ChatGPT - lives in a ChatGPT Project - skill.md as a Project file, the setup prompt as Project instructions, and each run starts inside that Project.
- Claude - lives in a Claude Project - skill.md as Project knowledge, the setup prompt as instructions, and each run starts in that Project.
- Gemini - lives in a Gemini Gem - the Gem’s instructions are skill.md plus the setup prompt, so the rules persist between sessions.
- Grok - lives in a Grok Skill or custom Bot with skill.md as the standing expertise - or attach the three files to a chat.
- DeepSeek - no persistent agents - upload skill.md at the start of each chat and re-paste the usage prompt per run (a well-packaged DIY prompt).
- Perplexity - lives in a Perplexity Space - upload the three files, paste the setup prompt into the Space instructions, and runs start in that Space.
- Microsoft Copilot - with Microsoft 365 Copilot it lives in a Notebook (skill.md as reference, setup prompt as instructions); in consumer Copilot, re-upload the files each session.
- Hermes - place skill.md in your Hermes workspace as the standing skill, then run the setup prompt - local-first, files stay under your control.
- OpenClaw - drop the three files into your OpenClaw workspace and point it at skill.md - setup runs over your usual chat channel.
- Town - share the three files with Town and ask it to keep skill.md as the standing rules for the job.
- Muse - give the three files to Muse and ask it to keep skill.md as the standing rules - approve the sample-data test first.

About 10 minutes: attach the files, run the setup prompt, approve the fictional-data test. It never touches real work until you approve the sample run.
