You can customize your FreshBooks account a few different ways, these include:
All of these customizations can be done yourself from the Settings area inside your account.
One other customization available is changing your FreshBooks subdomain.
Okay, imagine this - you are the owner of a company called Lemonade Stand and you have a FreshBooks account with the subdomain name LemonadeStand.freshbooks.com. Then, all of a sudden, you somehow acquire an inordinate amount of grapefruit. So much so that you decide to sell grapefruit juice instead. Now what are you supposed to do with LemonadeStand.freshbooks.com? Cancel it and get a new account? No!
You can email us from the Help page inside your account and we’ll change your domain name to GrapefruitKingOrQueen.freshbooks.com.
You can customize your emails by following the steps below:

Send By Post or Snail Mail is mail that is not sent through the internet. Yes, that’s right! On real paper.
With FreshBooks, you have the option of sending an invoice to your client by email or by post.
As soon as you click your “Send by Post” button, your invoice is printed and placed in a double-paned envelope along with a return envelope and sent directly to your client’s address via first class business mail within one business day. That’s right, you don’t have to print the invoice, buy envelopes or make runs to the post office.
Every time you send an invoice through Snail Mail, it will cost you one Stamp. This Stamp includes the price of printing, envelopes and postage to your client (return postage not included). When you first sign up for FreshBooks, we give you two free stamps to try it out. The cost of additional stamps is listed here:

Note: Prices subject to change.
To buy more stamps, just follow this quick step-by-step:
Every Snail Mail invoice has a perforated bottom section that your client can tear off, put into the return envelope and send back to you. Here is a what an actual Snail Mail invoice looks like:

A few things to note about Snail Mail:
You can send by post anywhere in the world through FreshBooks. The only difference is that two Stamps are needed for international (non-US or Canada) addresses.
If you accidentally or incorrectly send an invoice by post using FreshBooks, there might still be a way to stop the mail from being sent out. Please contact us immediately and we will do our best to assist you.
You can export clients from FreshBooks for Quickbooks by:
Please note though that you would have to adjust and massage a fair bit before it becomes useful in QuickBooks.
For the most part, users utilize FreshBooks for their day-to-day invoicing and time tracking, then they export their data to Quickbooks (or some other accounting package) on a quarterly or yearly basis.
FreshBooks connects to a wide array of tools and services. You can find the list from http://community.freshbooks.com/addons/
Each add-on has different specific requirements, but they all require two pieces of information:
See below for how to get these pieces of information.
If you are asked for your account URL, it is the same thing as your login page URL. Depending on your setup, it will look either like https://joesgarage.freshbooks.com or
https://joesgarage.billingarm.com. If you don’t know what your login page URL is, you can search for it with your email address.
Your API URL is the location on the Web where the add-on talks to your FreshBooks account. You probably don’t need to know anything about it except where to find it so you can copy and paste it into the add-on. Instructions to retrieve it are below.
Your Authentication Token is a verification code that allows third-party software and services to update and retrieve your account data. Your Authentication Token should be kept secret and only entered into software and services that you trust. Instructions to retrieve it are below.

Your Authentication Token is linked to your account password. Just change or reset your account password and your API key will also change. You will have to provide the new Authentication Token to all the add-ons you continue to use.
If you are an administrator, you can also disable all add-ons by following the same steps above but choosing to uncheck the checkbox next to “Yes, I agree to the API terms of service”.
