I had a problem printing a draft of a form. "Blocked plug-in". Had a chat with Paul on the site, and followed his suggestions for a fix. Then was able to print the form. I am a new user and have yet to make changes to the form and print it. Hoping for the best with that. Thanks, Verne

It is a little difficult to figure out how to load an existing form with the saved name. I also had to Google how to enlarge the font. Most of the help directions are outdated, but I did finally figure it out after a lot of wasted time. I DO like the program in general and love being able to convert and save in a different format.

Simple tool that increases productivity in office I'm a software engineer and have to deal with many documents everyday. Having a simple tool that has all the features needed for me to edit and handle all my documents makes my life easier. At the same time it saves me time to look up new tools and ways everyday. The UI is simple and intuitive, and it's easy to attach files, download and share it as needed. Overall it makes me more productive in office. My favourite feature is the electronic/digital signature feature. As a person in the IT department, I have to work with numerous documents and sign many of them. And this tool made that really easy for me. Also, the signature looks blended out and not out of place. Other than that the merging tool and conversion tool are also very helpful. Depending on my needs, sometimes I can convert a ppt into a pdf for easy access or for sending it to anyone. I also get to attach different pdfs together in whatever order needed. I don't have any major concerns. The only small problem I've had is regarding character recognition from scanned pdfs. Sometimes it is not entirely accurate. Though it is manageable for me.

Still learning and having a few… Still learning and having a few problems, but probably user-error related. Would undoubtably help if I had slowed down enough to watch the video, but just had to get this done.

PDFfiller do all the document from now on instead of MS. 1). 541 31ST St. Oakland, Ca. 94609-3203/Rental Property: so far tenants owe 4 mos. rent $8,056.00 2). The Alameda County superior court Case: Chung VS. Smith; 3). It's court request to use PDFfiller to do the Pleading, Ex-Parte and Declaration. 4). due to this instruction brought me to PDFfiller and learn how to do the legal document. 5).. From now on will use PDFfiler to do all the document: just use MS. do the preparation and copy and paste to the PDFfiler and that's all. -> From: Angel K. Chung-Gipson, 9/14/2021, 3:20 a.m.

I had an issue with accessing a form shared by a colleague. I wrote to the PDFfiller support team and received their response very swiftly. The instructions received via email were very clear and easy to follow. I was able to fix the issue within a very short time. I'm really impressed by the efficiency and quality of customer support.

I like it very much, I think it has great fearures... I like it very much, I think it has great fearures and it has helped me a lot... so much that I was ready to become a paid user. However, 2 of the last documents I uploaded to the system were cut-off and seriously changed (different format, things missing, etc) the uploaded document did not show as an identical version of the original document and that made me change my mind. I use it for contracts and they need to be exactly as the original document. These are legally binding documents, so because of that, I decided not to continue the service after the free trial ends.

It's great. Noticed some glitches on the forms, e.g. the text-in-th middle selection populates horizontally instead of vertically, making it impossible to see all that has been typed without scrolling across.

Click Sales (or Invoicing) in the left-hand menu. Select the Invoices tab. Scroll to the invoice you wish to edit and click on it to open it up. Make the necessary changes. Click Save and Close (or Save and Send).
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.
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.
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.
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.
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.
Select the CustomersTransactions Customer Tax Invoices option. 2. Click on the Actions option on the customer transaction line and select the Edit option, or you can click on the green supplier name link.
what I have discovered is to simply go back to the creation invoice tab and see the arrows in the top left corner, scroll through until you find your original invoice, then simply modify it and Save & close.
