When clients pay the vendor
Client-billed software keeps the firm out of subscription admin. Clients control their own accounts, and the firm avoids carrying software costs. The trade-off is that the software appears as a separate purchase, and clients may shop around or downgrade without telling you.
It also separates the software from your service. Clients see two bills and two relationships, which can make your bookkeeping fee look like only part of the picture. Clients may also compare the software cost on its own, which invites conversations about value that have little to do with your work.
