HubSpot vs Salesforce vs Build Your Own

Compare HubSpot when shared customer context across teams is the priority, Salesforce when the sales platform needs to support a broader operating model, and a custom CRM when a small set of unusual workflows creates most of the administrative work. Building is attractive when you can define the records, permissions, and handoffs precisely.

Imagine a consultancy where a signed deal needs an assigned delivery lead, a scope, a kickoff date, and a renewal reminder. The sales board can look complete while delivery still depends on someone copying those details into another system. The useful comparison is whether each option can carry that handoff through to completion without creating a second account record.

HubSpot: HubSpot describes contact records, deal pipelines, tasks, reporting, and connections across its customer platform. Source: HubSpot CRM overview. Our evaluation advice: start with its contact and deal model if marketing, sales, and service need a common customer history. Demonstrate the actual delivery handoff before selecting a plan.

Salesforce: Salesforce describes pipeline management, sales analytics, forecasting, and connections to its broader data platform. Source: Salesforce sales overview. Our evaluation advice: start with its sales and data platform if multiple teams need a shared sales operating model. Include an administrator in the evaluation so customization has an owner.

Build your own: evaluate a focused CRM against the same workflow. The custom design below is our proposed approach, not a claim that either vendor lacks every part of it. First test what configuration or an integration can already accomplish.

Start with companies, people, opportunities, activities, and delivery engagements. Make a won opportunity create a draft engagement with its source deal attached. Require a delivery owner before activation, retain a history of stage changes, and give staff a next-action queue. Integrate the existing mailbox and calendar rather than implementing either service.

The gain is a data model that follows how revenue becomes work. Sales and delivery can use different screens over the same account, with one place to correct a name or scope. You can add a specific approval rule without turning every employee into a CRM administrator. Owning the schema also makes future reporting and exports easier to design.

Ownership is most useful when it includes the source code, data model, export path, and operating documentation. Those make future changes reviewable and reduce dependence on a single implementer.

A contact table is only the beginning. Email synchronization, duplicate identity resolution, access controls, imports, and activity history need deliberate engineering. Keep an established platform if broad sales functionality is already being used effectively or if nobody can maintain a replacement.

Count administrator time, onboarding, integrations, and the cost of correcting duplicate customer records alongside licenses. For a build, include mailbox maintenance and migration reconciliation.

Use the same planning horizon for all three options. For a subscription, include licensing, setup, integrations, administration, and migration. For a build, include design, implementation, retained services, hosting, maintenance, support, and eventual handover. Count only subscriptions you can actually retire. If the custom option has no ongoing owner or maintenance budget, its estimate is incomplete.

Take ten recent won and lost opportunities through all three options. Include one shared contact, one reassigned account, and one reopened deal. Compare the number of manual transfers and missing delivery fields. Require a complete export and a backup restore before considering a cutover.

Agree on success criteria before the pilot and keep a rollback path. Expand the custom scope only when the observed improvement justifies the additional responsibility. A working prototype is evidence about the workflow; it is not yet evidence of dependable long-term operation.
