When your company deals with vast amounts of paperwork, it is too expensive, too time consuming, and too much hassle to try and deal with all your filing problems yourself. That is why, for any legal company or organization, finding a great courier service which also offers a great filing option can be very worthwhile. What you need to do though, is recognize how to find the best filing companies which are out there.
One of the first things to do when trying to find a genuinely good document filing service is to look for one which has been in business a long time. While it's true that every company needs to get their start somewhere, it is also true that you are always taking a risk if you choose to be that company which gives them their start. Look for an established company, and you know they have been doing something right, or they probably wouldn't have stayed in business as long as they have.
One of the best ways to find a high quality company, not just in terms of filing services but in any sector, is to speak to peers that might require companies which provide the same services. Find out who they use to provide their filing services and if they would recommend them, and you can be well on your way to finding a great filing company.
Price is another factor in selecting any company you do business with. While price and quality isn't necessarily the same thing, it's important to look for companies whose prices seem extremely high, or extremely low. Either may be a sign that you're not going to get service equivalent to the quality you are paying for.
You can also approximate the quality of a company by the other services which they may offer. For example, the courier company which offers a filing service may be more useful to you than a filing service alone. A filing company that also offers document destruction services could be another example of a combined company which might provide you with quality service.
Finally, if you're looking for the ultimate determining proof of the quality of a company, ask them for some references. If you can talk to someone that actually does business with a company, you can get the clearest picture of how good the service they offer is. A company unwilling to provide references is basically saying they have something to hide.
