Ask HN: Tool for tracking third-party services?

I would be grateful if someone knows of a tool - possibly a SaaS - that allows a small team to keep track of all the third-party services they are using and paying for. Ideally, it would support management of the details such as: * The membership tier/subscription type * Cost of the service (monthly, annual, per user etc) * Dates of any renewals (ideally with reminders) * Team members with admin/privileged access etc Any suggestions welcome!
