Then, we'll let you customize it to your firm. Most software products make you conform to their terminology. Not BigTime -- it allows you to organize your company the way you want. Whether it is Budget Categories, Cost Centers, or specific Field Value Names (e.g. type of account for billing) you have the flexibility to label however you desire.
