The service works well and is very convenient, however I was disappointed by the way I was able to complete an entire form but was not advised it was not free until the form was completed after spending a couple hours working on it. Since this is a pay service, the consumer should be advised immediately upon accessing any forms on an internet search. In order to preserve my work, I had no choice but to subscribe. Perhaps you should market a new service that charges by the document. I would have gladly paid for that up front. The service itself works very well.

The experience before I purchased a license was not so good. The chat session I was on kept ending. The CSR said because I was not logged into an account was the reason. At that point, I was trying to determine if I even wanted to purchase PDFfiller or not so why would I need an account. I finally ended up purchasing the product.

What do you like best?
I mainly use PDFFiller to fill out and sign forms. The auto-alignment tool for text blocks is very useful. I found the PDF to Word conversion procedure very powerful.
What do you dislike?
The limit in the number of pages and the size of the PDF file often forces me to divide the PDF into several parts before upload.
What problems are you solving with the product? What benefits have you realized?
Form filling and conversion to Word.

Once signed, the purchase order becomes an official contract which is legally binding for both parties. The supplier agrees to supply the items detailed in the purchase order, and the buyer agrees to pay the specified amount.
In a small company, the owner signs everything, and in a large company, each department head might sign the purchase order. The purpose of signing the purchase order is for the buyer to authorize the purchase and for the supplier to verify that an authorized person indeed issues the purchase.
Purchase orders At the point the PO is sent, it is not a contract. There are two ways that a purchase order becomes a contract: One way is if the seller accepts the terms of the purchase order by signing the PO or otherwise expressing acceptance in writing. The other way is by the seller's providing the ordered goods.
Issuing the Letter of Purchase Order (LPO) It serves as a binding agreement between the buyer and the seller. Process: Finalization: Once the PO is approved, it is converted into an LPO, which is then sent to the supplier. The LPO includes all agreed-upon details and acts as a confirmation of the order.
