In the hospitality industry, BTC stands for "Bill to Company." This is a billing arrangement where the guest's room charges and other specified expenses are not paid directly by the individual at checkout, but are instead sent to a pre-approved corporate account for payment. This is a standard procedure for business travelers whose companies have established a "Direct Billing" agreement with the hotel. To facilitate a BTC stay, the company typically provides a "Letter of Authorization" (LOA) or a corporate voucher specifying which charges (e.g., room only, or room plus breakfast) they will cover. The guest is usually still required to provide a personal credit card for "incidental" charges like the mini-bar or spa services, ensuring the company only pays for the pre-authorized business-related expenses.
