Some notaries can accept lower fees than others because they are desperate for the work, perhaps they are just starting out and eager to gain experience. I was with one company for over thirty jobs and they had a huge lag time in paying for the work. I would tell them that if certain jobs were over 150 pages I would need more money, or over a certain distance, the same. They agreed to these terms but guess what? If a signer refused I was left without a travel or even printing fee, something I thought unthinkable. But there it was in their terms and conditions. I no longer work for them because every 10th job was a refusal so that means all my earnings averaged less.I am still awaiting payment for jobs I did as far back as July. Being a notary signing agent isn't a cake walk. There are many ills, low fees, ridiculous accommodations, huge distances, and companies that will let you print out documents twice and travel twice but only pay you once.
I would say for the first year, expect to make mistakes, not earn top dollar, and work on perfecting your craft. If you are good at what you do, you will be noticed and better-paying jobs come along. While it may be tempting to 'force' companies to pay more we are hurting the borrowers, the people we are trying to serve when we say we aren't available.
Oh and on SnapDocs if a job is too low-paying I let them know. Sometimes they will call you back to see if they can work out something fair to both parties. You don't always get it back but I like to treat others as I would want to be treated.
