The Scenario
You are a billing coordinator. It is Wednesday morning and your manager has just asked you to send all 30 outstanding invoices to customers before end of day.
The invoice IDs are already in your Excel workbook — column A of the Invoice Send tab. You need a "SENT" or "ERROR" status written back into column B for each one. Your manager wants to see the results before she leaves at 5 PM.
The bad version of this Wednesday:
- You open Zoho Inventory and navigate to each invoice one at a time
- You click the email icon, confirm the recipient, hit send
- You switch back to the workbook, type "SENT" in column B, move to the next row
- By invoice eight you have accidentally sent invoice #1041 to the wrong customer because the tabs got confused
- By 4:45 PM you have sent twenty-two invoices and are still going.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook that reads the invoice IDs in the Invoice Send tab and calls Zoho Inventory's bulk email API for you, then writes the send status back into column B.
Open the SheetXAI sidebar and type:
For every invoice ID in column A of the Invoice Send tab, email the Zoho Inventory invoice to the customer on record and write SENT or ERROR into column B. If a send fails, include a brief error reason in column C.
SheetXAI reads each ID, calls Zoho Inventory to send the invoice email to the customer already associated with that invoice, and writes the result back. Thirty rows, thirty statuses, done before lunch.
What You Get
- Column B — SENT for every successfully emailed invoice, ERROR for any that failed
- Column C — error reason for any failures (wrong email on record, invoice already paid, etc.)
- All sends use the customer email address on the Zoho Inventory contact record — you do not need to supply emails in the workbook
Failures are surfaced, not silently skipped. If invoice #1039 fails because the contact has no email address, you know immediately, and you can fix the contact in Zoho Inventory and re-run that row.
If you want to customize the email subject line or add a message body, include that in the prompt. SheetXAI passes it to Zoho Inventory's email parameters.
What If the Data Is Not Quite Ready
Invoice send lists are rarely just a clean column of IDs. SheetXAI handles pre-send checks and cleanup in the same prompt.
When some invoice IDs in the workbook have already been paid
You do not want to send a payment reminder for an invoice that was settled last week.
For every invoice ID in column A of the Invoice Send tab, first check the invoice status in Zoho Inventory. If the invoice is already paid or voided, write "ALREADY CLOSED" in column B and skip the send. For all open invoices, email the invoice to the customer and write SENT or ERROR into column B.
When you want to send only invoices overdue by more than 14 days
Your policy is to wait two weeks before sending the first reminder. You have a mix of ages in the Invoice Send tab.
For every invoice ID in column A of the Invoice Send tab, check the due date in Zoho Inventory. Only send the email for invoices that are more than 14 days past due. For invoices not yet overdue, write "NOT YET DUE" into column B. For overdue invoices, send the invoice email and write SENT or ERROR.
When the workbook has duplicate invoice IDs
Someone copy-pasted the list twice and there are 30 rows but only 22 unique IDs.
Before sending, deduplicate the invoice IDs in column A of the Invoice Send tab. For any duplicate, keep the first occurrence and write "DUPLICATE — SKIPPED" into column B for the later rows. Then send the invoice email for each unique ID and write SENT or ERROR into column B.
When you want to send a custom message with each invoice email
Your manager wants a specific message included with each send.
For every invoice ID in column A of the Invoice Send tab, look up the customer name in Zoho Inventory. Email the invoice with the subject line "Invoice from SheetXAI Inc — payment due in 7 days" and the body "Dear [customer name], please find your invoice attached. Payment is due within 7 days. Thank you." Write SENT or ERROR into column B.
The pattern: the workbook is the task list, the prompt is the logic, and Zoho Inventory does the sending.
