Coast to Coast ALWAYS starts with low ball offers. I don't take it personal, it's just expected. I've done lots of work for them with no complaints. They pay at 30 -40 days, but they do pay without issues.
NEVER accept their initial fee, just say NO, but counter with what you expect to get paid - my minimum fee for a real estate deal of any kind and local is $100. I get it from often from Coast to Coast and others, even when the initial offer is much less. Scan backs add $25 more to my fee.
With Snapdocs offers, I always respond with a reasonable fee, if I'm available. You'll be surprised, you often get the signing at your fee. Remember is Snapdocs is NOT a signing service, its nothing but software package used by MANY low-ball signing services, but some signing services that use Snapdocs DO offer good initial fees or will quickly OK reasonable fees.
If a Snapdoc or other signing service with a IM app calls you about a signing, especially if is a ASAP signing, its because they are desperate and need you, but probably don't want to pay your fee. Too bad, I never lower my fee after I have stated a fee in an IM app.
Say the initial fee offered is something crazy - $65 but its a ASAP or TBA for today signing and its already 4:30 p.m. Counter at $125 through the app. Normally its a $100 signing but they need to schedule someone NOW and don't have time search for someone to bite at $80 or $90. There is a good chance you'll get the signing at $125. If they call you - stick to your fee and you will get it often.
