What you need to have ready for your delivery driver will depend on the local courier service that you do business with. If it is a company that you regularly do business with and have a long term account with, they may have systems in place like online order placement and address books which might mean that you have very little to have to give the driver. The most important thing is to have your package or delivery packaged securely and safely, according to any rules that the courier company may have in place. Often, if you place your orders online you will have a shipping label that you can print straight from your computer to place on your delivery; otherwise you may have to fill out the standard paperwork that your regular courier company requires when making any delivery.
Again, the needs of any one particular courier service will be different from company to company. The most efficient among these will have all the processes of a pickup automated through their computer systems as much as possible. For example, an older business model might require you to fill out a billing form of some kind when the driver comes to make a pickup. More advanced companies have integrated electronic billing now, so by simply entering your account number the driver ensures that the charge is simply applied to your regular account so that you can receive an orderly and efficient monthly statement with all shipping's costs itemized and sorted at the end of your billing period. It makes for a more efficient pickup, and for more efficient billing practices.
The most important thing, especially if you're just starting to use the services of a city courier service, is to make sure that you're really familiar with their guidelines for how packages have to be packed and labeled. Most companies have rules in place about this, and for good reason, as deliveries that are improperly packed can become damaged, which they don't want to be liable for, or do not pack effectively which costs them space in their vehicles. If your packages are not packed and labeled correctly you could be charged a fee for the driver having to return later in his run after you have repacked your shipment, which is something that most companies would rather avoid. If you're shipping something different than what you have in the past, simply call your account representative and ask beforehand how the shipment should be packaged and labeled.
