Questions businesses ask

How do I create an invoice for free?

Enter your business name and customer details, add the work or products you are billing for, and set your issue date and payment deadline. Review the totals, then select Download PDF. No account is required.

How do I save my invoice as a PDF?

Select Download PDF to open your browser’s print dialog. Choose Save as PDF (or the PDF option on your device), check the preview and save the file. You can then attach it to an email to your customer.

What should I include on an invoice?

Include your business and customer details, a unique invoice number, issue date, payment due date, item descriptions, quantities, prices and the total due. Add any applicable tax, discounts and payment instructions. Tax requirements vary by location.

Can I add my logo and change the currency?

Yes. Upload your logo in the invoice builder and select the currency you bill in. Add line items, tax, discounts and shipping, then review the invoice before downloading.

Can ChatGPT or Claude make an invoice?

Yes. Add the AI Invoice Generator as a connector and ask in plain words, like "invoice ABC Corp $1,200 for September consulting, due in 30 days". You get a finished invoice to download as a PDF, with totals, tax and due date worked out.

Do I need an account?

No Alder account is needed to create and download an invoice on the web. To use ChatGPT or Claude, you need an account with that service and must set up the connector.

Is it really free?

Yes. No subscription and no invoice limit.

What can I ask for?

Who to bill, what for, how much and when it is due. Add tax, a discount, shipping or several line items in the same sentence, and the AI fills them in.
