so far so good. Not the easiest to find document while logged in. I find I have to do a search on the document from a web browser to get to it. PFDfiller couldn't find the doc from within the app.

All I needed was to fill in 5 W2 2024 forms for church staff, and pdfiller was easy to use. Since I won't be needing it for anything else, I don't want the charge on my card. I will remember pdfiller should a future need arise.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
If an incorrect invoice has been sent, the business must issue a cancellation invoice with its own, new invoice number. This will include a negative invoice amount, as well as the original invoice number and the date it was issued. Then, a correct invoice can be raised with a different invoice number.
How do you fix an invoice mistake?
If you have already issued the invoice, but the customer has not paid, send a friendly email or make a polite phone call explaining the mistake, and then issue a new invoice. If the customer has already paid, make a correction adjustment on a future invoice, or issue another invoice or credit correcting the mistake.
Can you change an invoice once issued?
It's not illegal, per se, to amend an invoice that you've raised, but it is covering your back as it could invite litigation if you amend your own version of it without cancelling the original version — in particular if the customer has actually paid against the original.
Do you have to pay an invoice if the company made a mistake?
Sending out the correct invoices is the responsibility of their accounting department and its employees, not the customers. If they made a $400 mistake, then unless they are someone whose products you'll need to run your business on a regular basis, they eat the mistake.
Can you cancel an invoice?
Technically, you should never delete an issued invoice but instead use a credit note to cancel the invoice. It will also warn you when you attempt to delete an invoice, and instead suggest the option of using a credit note to cancel out the invoice in your accounts.
How do I edit an invoice?
To edit the invoice, you can either click the Edit Invoice button in the screenshot above, OR you can find it on the main Invoices page, click the drop-down arrow to the right and click Edit. You'll be able to edit any of the data you entered when creating the invoice.
Can you change an invoice?
Changing invoices that have already been issued If you would like to change the original amount issued on the invoice to either higher or lower, you will need to issue a credit note. Instead, you can simply create a new invoice with the corrected information, and send the new bill to your customer.
How do I edit a tax invoice?
Find and open the unpaid invoice. Search for the invoice if you know the customer name, invoice number or invoice amount. Click on Actions Edit and adjust the invoice details. Click Print Preview to check your invoice layout and details. Click Save.
