The Scenario
It's the last day of the month and you have 80 client invoices to create. The billing sheet has been sitting in Google Sheets for two weeks — client ID in column A, service description in B, quantity in C, unit price in D, tax rate in E — and every row represents a client who expects an invoice in their inbox today.
The bad version:
- Open sevdesk, click New Invoice, search for the contact by client ID, add each line item by hand, set the tax rate, save, click Send — then repeat from the top for client 2.
- By invoice 15 you're copying the wrong service description into the wrong client's invoice because the rows are starting to blur together.
- You send invoice 47 before realizing you pulled the wrong unit price. Now you have to void it, recreate it, and resend — losing another 20 minutes on a day you don't have any to spare.
Month-end billing is not supposed to consume an entire day. The data is already in the sheet. It should not have to be retyped into sevdesk field by field.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside Google Sheets that reads your spreadsheet and talks to sevdesk directly. It creates the invoices, marks them as sent, and writes the confirmation back into your sheet.
For each row in my Invoices sheet, create a sevdesk invoice using the contact ID in column A, line items in columns B through E, and mark each invoice as sent via email after creation — write the invoice number into column F
What You Get
- One sevdesk invoice created per row, with line items populated from your sheet columns.
- Each invoice marked as sent via email to the contact on record in sevdesk.
- Invoice numbers written into column F as confirmation — so you have a reference for payment tracking.
- Any row that fails (contact not found, tax rate invalid) surfaces an error in column F rather than a silent skip.
What If the Data Is Not Quite Ready
Some rows have multiple line items that need to be grouped under one invoice per client
Group my Invoices sheet by the client ID in column A — for each unique client, create one sevdesk invoice with all matching rows as separate line items using columns B through E — write the invoice number into column F next to the first row for each client
The unit price column has some cells formatted as text with currency symbols
Clean column D of my Invoices sheet — strip any currency symbols and convert values to numbers — then create sevdesk invoices for every row using the contact ID in column A, description in B, quantity in C, cleaned price in D, and tax rate in E — write the invoice number into column F
Invoices span two tabs: Domestic and International with different tax rates
Create sevdesk invoices from both the Domestic tab (columns A through E, all rows use 19% tax) and the International tab (columns A through D, tax-exempt) — write the invoice number back into column F on each tab
The billing data needs cleanup, validation, and invoicing in one pass
Check every row in my Invoices sheet: skip rows where column A is empty or column C is zero — for valid rows, create a sevdesk invoice using columns A through E, mark as sent, and write the invoice number into column F; for skipped rows, write SKIPPED in column F with the reason
Combining the data check and the invoice creation in one prompt means you end up with a complete, annotated result rather than a partial run and a guessing game about which rows went through.
