How do I get AI to email overdue invoices every Monday?
Get AI to email overdue invoices every Monday without exporting aged receivables or pasting Xero into chat. Croft syncs Sales invoices on your private server, and your assistant builds the weekly overdue email automation on top.
Quick answer
To get AI to email overdue invoices every Monday, connect Xero on Croft, then connect Claude or ChatGPT. Croft keeps a tidy copy of Sales invoices (plus bills, contacts, payments and accounts) on your private server. Ask in plain words: Every Monday, email me the list of overdue invoices. Your assistant builds that automation on Croft. It runs on a schedule, can read and draft with your own Claude or OpenAI account, and emails finance. You do not export aged receivables into chat, and you do not give the AI your Xero login.
That is the site’s pitch in one job: your business data, ready for your AI, including the automation you build on top of it.
Stop chasing overdue invoices by hand every Monday
The overdue list already lives in Xero. The usual ways of getting an AI to chase it are a poor fit:
- You export aged receivables to a spreadsheet, paste it into Claude or ChatGPT, then copy the summary into an email. Next Monday you do it again.
- You leave a reminder on your calendar and click through Xero yourself. The list is current, but nobody else can ask a follow-up, and nothing runs if you are away.
- You drop a Xero login or API key into a prompt so the model can “just fetch it.” The AI is now holding credentials it should never see.
Finance people and developers hit the same wall. The data is fine. There is no current, controlled copy for the AI to read, and nowhere to hang a Monday email next to that copy.

Manual chase vs spreadsheet export vs Croft automation
| Need | Manual chase in Xero | Export spreadsheet into chat | Croft automation |
|---|---|---|---|
| Current overdue invoices | Live, if you click through | Stale the moment you export | Tidy Sales invoices copy on your private server |
| Named data the AI can read | You read the screens yourself | You hope the columns make sense | Sales invoices, Bills, Contacts, Payments |
| Says how fresh the numbers are | Whatever Xero shows right then | No | Yes, for example “synced 12 minutes ago” |
| Keys stay off the AI | You are logged into Xero | The file still left Xero | Croft holds the connection |
| Runs every Monday without you | No | No | Schedule or event on your private server |
| AI can summarise and draft the email | Manual | One-off paste | Your own Claude or OpenAI, no per-automation fee |
| Who on the team can see or ask | Whoever has Xero | Whoever has the file | Admins decide per source |
| Same job from Claude or ChatGPT | Another login | Paste the file again | One copy, many assistants |
Croft is not “connect your AI straight to Xero.” Claude or ChatGPT reads the curated copy on your server. Keys never reach the AI. Setup: Xero connector, your data, connectors, automations.
Steps: trial, connect Xero, connect AI, ask for the Monday email
- Start a free trial to get a croft, your private server. 7 days, no card.
- Connect Xero. Connecting starts the sync. There is nothing else to install. Croft keeps invoices, bills, contacts, payments and accounts as named datasets you can browse on the Data page: Sales invoices, Bills, Contacts, Payments, plus ready-made summaries such as who owes you most. Freshness is noted on the copy. New sources are visible to admins until you open them to the team or to named people. You choose how much history to keep.
- Connect Claude or ChatGPT. Add Croft as a connector and connect. Cursor and Grok use the same kind of link. Developers can point a coding assistant at the same croft.
- Ask for the automation in plain words: Every Monday, email me the list of overdue invoices. Your assistant builds it on Croft. It can run every Monday (for example at 8am), read overdue Sales invoices from the synced copy, summarise or draft with your own AI account, and email finance. You can also ask it to Draft an invoice for Acme’s overdue retainer when you need a one-off, not only a schedule.
The connection is MCP, so any assistant that speaks it can use the same croft. The AI does not log into Xero. Company login sits in front of the croft, so teammates open the data and any related app without a separate Xero login.
Equal halves: synced Xero data and the Monday automation
Asking “who is overdue?” is half of it. The other half is building the weekly job on that same connection.
On the data side, Croft keeps Sales invoices (and the rest of the Xero set) as named datasets your AI can query. Browse them on your data. The AI says when the numbers were last synced. Admins decide who sees each source. Keys stay with Croft.
On the automation side, ask your assistant to build the Monday overdue email as a small app. From automations:
- It runs on a schedule or an event, on your private server.
- It can read, summarise and draft using your own Claude or OpenAI account (your subscription, not a resold one).
- It can email, alert or update an app when it finishes.
- You build it by asking in plain words. There is no per-automation fee.
- Destructive actions ask first, and every run is logged with who asked and which AI did it.
That is the equal half of the product: Xero data ready for your AI, and a place that AI can hang the Monday overdue email on.
Everyone’s AI also shares team memory. Tell Claude “remember for the team: overdue invoices over $5,000 need Sam on the Monday email” and ChatGPT knows it too.
FAQ
How do I get AI to email overdue invoices every Monday?
Connect Xero on Croft so Sales invoices stay in sync on your private server. Connect Claude or ChatGPT, then ask in plain words for a Monday overdue invoice email. The automation runs on your server and emails finance. Start from your data.
Can Claude email overdue invoices every Monday?
Yes. Ask Claude to build that job as a small app on Croft. Details: automations. The same Xero copy powers answers in chat and the scheduled email.
How do I automate overdue invoice reminders with AI?
Sync Xero, connect your AI, and ask for a scheduled automation that emails the overdue list. Croft runs it on your private server. There is no per-automation fee. See pricing.
Why not export aged receivables into ChatGPT each week?
Exports go stale and multiply as files. A Croft copy stays current, sits on your server, and the AI says how fresh it is. The Monday email uses that same copy.
Should I give an AI my Xero login for reminders?
No. Croft holds the connection. The AI never sees a password or API key.
Who gets the Monday overdue email?
You choose recipients when you ask for the automation. Admins decide who can see the Xero source. Company login sits in front of the croft.
Can ChatGPT build the same Monday overdue email?
Yes. Connect ChatGPT the same way. Cursor and Grok work too. Each assistant uses the sources you have allowed, and they share team memory.
Does the overdue email automation cost extra?
No. Schedules are part of your plan. AI-powered steps use your own Claude or OpenAI account. Solo from $24/month billed annually, Team $99/month billed annually, Enterprise custom. 7-day free trial, no card to start. See pricing.
