In Google Drive create a folder 'Invoices' with one sub-folder per month, e.g. '2026-10'.
Open Grok Bot, tap + (New chat) then Create new Bot. Give it a name that says the job, so you always know who does what.
Copy the prompt below, fill in your details and send it. Connect your email and Google Drive when asked.
Ask: 'Do last month now, but don't send anything.' Compare the index with your own records.
If it missed invoices that arrive another way (WhatsApp, supplier portal), tell it where they come from or forward them to your email.
Ask it to run on the [3rd] of each month and message you for approval.
Read the index, reply 'approved', and the Bot emails the bundle to your accountant.
Every month on the [3rd] at [9 a.m.]: 1. Find all supplier invoices from last month in my email ([email]). Look for PDFs and emails with words like invoice, bill, tax invoice. 2. Save each PDF to Google Drive > Invoices > [YYYY-MM], renamed 'supplier โ date โ amount'. 3. Make an index sheet: supplier, date, invoice number, amount (MYR), SST if shown, file link. 4. List anything that looks like a duplicate or is missing a number. 5. Message me the totals and ask for approval. Only after I say 'approved', email the folder link and index to [accountant email]. Never pay, never delete emails.
