Best HubSpot and CRM implementation partners for B2B (2026): who implements the CRM, and what they charge
A HubSpot or CRM implementation partner sets up the data model, pipelines, lifecycle stages, routing, integrations and reports a B2B team actually uses. The useful split is a firm whose main work is HubSpot, and a RevOps firm that will also build HubSpot, Salesforce or Attio as part of a wider system.
OneGTM is in the second group, so read that card with that in mind. We implement CRM architecture inside a RevOps engagement. We are a GTM engineering firm, and the HubSpot directory partners further up this page are the ones whose published business is HubSpot implementation. For the CRM products themselves, see CRM for startups.
Key takeaways
- RevPartners publishes HubSpot implementation prices: Sales Hub from $1,500, Service Hub from $2,000, and demand generation infrastructure from $3,000, with a stated go-live as short as 14 days.
- Aptitude 8 is an Elite HubSpot Solutions Partner that does architecture, implementation, migration and integrations, and says it does not sell inbound marketing or creative.
- SmartBug, New Breed, Impulse Creative, Huble and Six and Flow are HubSpot partners that also cover implementation. Most of them do not publish a project fee.
- OneGTM, Elefante RevOps and Operatus take on CRM work as RevOps. OneGTM works in HubSpot, Salesforce and Attio. Operatus publishes Salesforce implementation projects.
- Ask who owns the portal when the project ends, and whether reporting ties to pipeline in the CRM.

RevOps firms that implement the CRM
These firms take the CRM as part of revenue operations, which is the right call when the problem is routing, data and reporting, and HubSpot may not be the only system. OneGTM is listed here because we do this work. The specialist HubSpot partners are in the group above.

How to choose a CRM implementation partner
Start with the CRM you already pay for. A HubSpot Elite partner is the wrong first call for a Salesforce rebuild, and a Salesforce shop is the wrong first call for a Marketing Hub setup. OneGTM, Elefante and a few of the HubSpot firms will touch more than one CRM. Ask which one they implement most often.
- Ask for a data model and a lifecycle diagram from a recent B2B project, with the client named.
- Ask who configures the portal: a named consultant, or a rotating bench.
- Get the fee, what is out of scope, and who pays for HubSpot licenses and integration tools.
- Ask for admin access and documentation when the project ends. You should own the portal.
- Ask how pipeline reporting will be checked against closed revenue, not only against form fills.
A project, or an ongoing RevOps retainer
An implementation has an end: the pipelines, properties, workflows and reports are live, and your team can run them. RevPartners, Aptitude 8, Impulse Creative and Huble sell that project. A retainer means someone keeps owning routing, data hygiene and changes every month. RevPartners, Elefante, Operatus and OneGTM sell versions of that.
Buy the project when the CRM is new or tangled and you have an admin who will own it after. Buy the retainer when nobody inside will keep it clean. The fractional RevOps list goes deeper on retainers.
When the CRM and the outbound should be one build
A HubSpot partner can leave you with a clean portal and an empty pipeline. If you want the implementation and the lists, signals and sequences that feed it, that is the engagement OneGTM scopes.
We work in HubSpot, Salesforce and Attio. The RevOps agency page has the scope.
- The CRM project is scoped, and nobody owns the data that will fill it.
- Marketing and sales disagree on lifecycle stages.
- Leads are created and then sit, because routing was left for later.
- You want enrichment and outbound written back to the same CRM.
