You need t tell people that if they enter numbers with commas, the IRS filing process does not work. After lots of time and trial/error, I stumbled across that as the cause of my problems.

Easy for On the Go Editing This works great for creating editable PDFs & exporting them to clients. Can send for signatures and edit details for initial, etc. I don't dislike it but it could offer more features for the price.

pdfFiller Good for buisness My overall experience with pdfFiller has been a positive one. I would recommend to others in our industry that deal with a lot of forms to connect with customers. The ability to use the pdfFiller for our customers to submit forms that needed editing in the field. The lack of options on the form editor to add buttons and boxes for surveys.

Great customer service and solid product. I don't usually leave reviews, but this product deserves my time. Works very well in filling PDFs. Typing, checking boxes (using the checkmark or "x" feature), filling out tables, etc. Saving and editing again works well, though it isn't entirely intuitive the first time. Customer service was absolutely awesome! I realized, after signing up for a paid subscription, that I no longer needed the service. I cancelled online (or THOUGHT I did), but I must've had a glitch. When I got billed, I called and they issued me a refund no questions asked and zero hassle. Customer service was incredibly helpful. Product was great for filling out multiple long pdfs that only had slight variations (saved a copy and changed only the fields that I needed). Easy to use and quick to learn. I cancelled my subscription only because I realized I wouldn't be using it enough to justify the cost. Life changes!

It was so easy It was so easy! I had to go back a few times to edit some pages of the document, but the process was simple. This was my initial use of the site, and, so far, I'm very pleased.

Instructions and Help about Unify Invoice For Free

Unify Invoice: make editing documents online a breeze

Having the right PDF editor is vital to improve the workflow.

If you hadn't used PDF file type for your business documents before, you can switch anytime — it is easy to convert any other file format into PDF. This makes creating and using most document types simple. Multiple different files containing different types of content can be merged into just one PDF. That’s why it is perfect for basic presentations and reports.

Though numerous online solutions offer PDF editing features, only a few of them allow adding digital signatures, collaborating with other users etc.

Use pdfFiller to annotate documents, edit and convert them to many other formats; fill them out and put a digital signature, or send to others. All you need is a web browser. You don’t have to install any programs. It’s an extensive platform available from any device with an internet connection.

Use one of the methods below to upload your document template and start editing:

01
Drag and drop a document from your device.
02
Open the Enter URL tab and insert the hyperlink to your file.
03
Get the form you need from the catalog using the search.
04
Upload a document from a cloud storage (Google Drive, Box, Dropbox, One Drive and others).
05
Browse the Legal library.

Once a document is uploaded, it’s saved in the cloud and can be found in the “My Documents” folder.

Use editing features such as typing text, annotating, blacking out and highlighting. Change a page order. Once a document is completed, download it to your device or save it to the third-party integration cloud. Collaborate with people to complete the fields. Add images into your PDF and edit its layout. Add fillable fields and send for signing.
