Export Open Invoice Payment Status From Lexoffice to an Excel workbook

The Scenario

Every Monday the finance lead gets the same message: "Can you send me where we stand on open invoices?" It means opening Lexoffice, filtering to open status, reading through each invoice for the payment details, building a workbook, and sending it — 90 minutes of work for a snapshot that's already slightly stale. Last week the workbook had a formula error in the outstanding balance column. The week before, someone had added a tab that confused the whole structure. This week the finance lead wants the snapshot by 9 AM.

The bad version:

• Open Lexoffice, filter to open invoices, read through each record for invoice number, contact, total, paid amount, and outstanding balance
• Paste each row into the Excel workbook manually, watching for invoices with partial payments that need a calculated balance column, not just a status flag
• Send the workbook, get a reply 15 minutes later asking for due dates, and rebuild it from scratch because the original didn't include that column

Ninety minutes every Monday for a dataset that already exists in Lexoffice.

The Easy Way: One Prompt in SheetXAI

SheetXAI is an AI agent that lives inside your Excel workbook. It connects to Lexoffice and pulls the invoice and payment data directly into the workbook — no filtering, no copy-paste, no formula errors.

Open the reporting workbook and type:

List all open Lexoffice invoices and pull the payment status for each one into this workbook with columns for invoice number, contact, total, paid amount, and outstanding balance

What You Get

• A complete list of open Lexoffice invoices written into the workbook — invoice number, contact, total, paid amount, and outstanding balance per row
• Partial payment amounts reflected accurately — not just open/closed flags
• A shareable snapshot ready in two minutes instead of ninety

What If the Data Is Not Quite Ready

You only want invoices from the past 90 days

List all open Lexoffice invoices created in the last 90 days and write invoice number, contact, total, paid amount, outstanding balance, and due date into this workbook

Invoice IDs are already in the workbook and you want to enrich them

For each invoice ID in column A fetch the payment details from Lexoffice and write the paid amount and due date into columns B and C

You want to flag overdue invoices automatically

Pull all open Lexoffice invoices into this workbook with invoice number, contact, total, due date, and outstanding balance — add a column marking any invoice whose due date is more than 30 days ago as "overdue"

Full accounts-receivable snapshot in one shot

Pull all open Lexoffice invoices into this workbook with invoice number, contact, total, paid amount, due date, and outstanding balance — calculate days overdue for each based on today's date, flag anything more than 60 days overdue as "escalate," and sort by outstanding balance descending

One prompt builds the complete view for the Monday morning meeting.
