I was told by a lawyer that the cost of his writing a Consent Order would be $2000.00.
Instead, I used PdfFiller and it cost me $144 for a year's subscription with the same results.
Kind of a No Brainer.
Thank you PdfFiller.

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 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.
What happens if an invoice is incorrect?
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.
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 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.
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.
How do you apologize for an incorrect invoice?
You must apologize for sending a collection letter to the reader by mistake. State the customer's current status of the account. Appreciate the understanding and patience of the customer. Be apologetic about sending the collection letter by mistake. State the current status of the customer's account.
How do you apologize for a mistake professionally in a letter?
Acknowledge Your Mistake. The first thing you need to do is take ownership for your mistake and admit that you were in the wrong. Apologize. Accept Responsibility. Offer an Explanation. Take Action. Express Your Regret. Promise it Won't Happen Again.
