If your business sells subscriptions - SaaS products, membership services, recurring maintenance contracts - you'll quickly find that a single Deal object isn't a great fit for ongoing revenue relationships. A Deal is designed to represent a one-time sales motion. A subscription has a start date, a renewal date, a tier, a status, and a billing cadence. Those are fundamentally different data requirements.

A Subscription Custom Object lets you create one record per subscription, associate it with the relevant Contact and Company, track its properties independently, and trigger renewal workflows based on the subscription's own data - without forcing that data into a Deal structure it wasn't built for.

Estate agencies, equipment rental companies, fleet management businesses, and any organisation that sells or manages physical or digital assets often need to track the asset itself as a first-class record in the CRM - not just the person who owns or rents it.

A Property or Asset Custom Object can hold all the details about the asset - its specifications, location, status, and history - and be associated with the relevant Contacts (e.g. current owner, prospective buyers) and Deals (e.g. the active sale or rental agreement). This gives you a complete view of both the asset's lifecycle and the people attached to it, without duplicating data across contact properties.

Businesses that run events, training programmes, or online courses need to track the event itself as a distinct record - not just the attendees. If you're running 12 events per year with 200 attendees each, trying to manage that via contact properties and lists becomes unwieldy and unreportable very quickly.

An Event or Course Custom Object gives each event its own record with its own properties, associated with the Contacts who registered, attended, or completed it. You can then report on event performance, attendance rates, and revenue per event - all within HubSpot, without needing a separate event management tool.

Professional services firms - agencies, consultancies, law firms, accountancy practices - often need to track client projects separately from the Deal that won them. Once a Deal closes, the work begins - and the project has its own timeline, milestones, team members, and status that have nothing to do with the original sales pipeline.

A Project Custom Object lets you track post-sale delivery within HubSpot, associated with both the original Deal and the Contact. This closes the loop between sales and delivery, gives leadership a complete revenue-to-delivery view, and removes the need to maintain a separate project management spreadsheet for data that belongs in the CRM. If you're using HubSpot's full suite, this kind of joined-up data model is where the real value lies.

HubSpot has a native Products library, which works well for straightforward product catalogues. But if your products have complex, instance-specific configurations - think bespoke software licences, configured machinery, or customised service packages - the native Products object may not be flexible enough to store everything you need against each sale.

A Product Configuration or Licence Custom Object lets you capture the unique details of each instance of a product sold - associated with both the Deal and the Contact - without polluting your master product library with instance-specific data. This is particularly useful for businesses that need to support customers post-sale based on the specific configuration they purchased.
