HubSpot Agency Pricing: Cost, Timelines and the Steps of a Successful Project
The price of a HubSpot agency depends above all on the project scope: it generally ranges from a few thousand euros for one-off support to several tens of thousands of euros for a full CRM overhaul, integrations included. For an executive who has to decide between several quotes, the real question is not just "how much does it cost" but "what does this budget concretely change in sales performance, and how quickly". This guide details what drives the budget, the phases of a deployment, the steps of a successful project and the method for checking a partner's reliability before signing.
How much does a HubSpot agency cost?
A HubSpot agency's price is generally built around three types of engagement: audit and scoping, implementation or migration (Sales Hub, Marketing Hub, integrations), then long-term support, often billed monthly. The amount depends on the scope and is set after scoping. It does not include the HubSpot subscription itself, detailed in our complete guide to HubSpot prices and plans.
However, the amount says nothing about the value produced: two projects with the same budget can generate very different results depending on how the agency structures the pipeline, trains the teams and connects the CRM to the rest of your IT system.
The factors that make the price vary
Three criteria weigh particularly on the final budget: the complexity of your sales and marketing processes (a multi-business-unit pipeline with complex attribution rules costs more than a simple pipeline), the scope of the Hubs involved (Sales Hub alone costs less than a deployment combining Marketing Hub, Service Hub and advanced automations), and the level of integration with your other tools (ERP, invoicing, telephony), developments that push the bill up but also drive most of the return on investment.
Agency or internal hire: what budget for what result?
Faced with an agency quote, many executives spontaneously compare it with the cost of an internal hire. The calculation is rarely as simple as it looks once you factor in ramp-up time, turnover and the opportunity cost of a project that falls behind. Our article on the role of a HubSpot agency and when to bring one in helps you decide.
How long does it take to deploy HubSpot?
Allow about 3 months to deploy HubSpot with an agency, versus 6 months on average for a project run without specialist support. The timeline depends less on company size than on the complexity of the sales pipeline, the number of Hubs to activate and the volume of data to migrate. Some simple projects move quickly; others, involving several Hubs and a heavy migration, take longer.
The phase-by-phase timeline
Phase 1 — Audit and scoping: mapping of the existing pipeline, the tools in place and the growth objectives, concluded by a detailed schedule and validated milestones.
Phase 2 — Configuration and data migration: the most time-consuming phase, covering the configuration of pipelines and automations and the cleaning and transfer of historical data.
Phase 3 — Integrations and automations: connection to the other tools in your IT system (telephony, ERP, invoicing) and testing in real conditions before final activation.
Phase 4 — Training and sales adoption: salespeople are trained on concrete cases drawn from their own pipeline. This last phase determines whether the CRM will actually be used once the agency has left.
Setup time is sales directors' number one objection: nobody wants to freeze their pipeline for 3 months. In practice, an agency structures the deployment so that salespeople keep selling on the old tool while the new one is built, then switches over in one go when everything is ready and validated.
The steps of a successful HubSpot project
A HubSpot agency does not just configure fields and pipelines: it handles scoping the sales need, integration with your existing tools, migration of historical data, then training and adoption follow-up.
1. Scoping and audit
The agency first audits the current sales process, the existing tools and the pain points raised by salespeople, to precisely scope the work: pipelines to build, priority integrations, data to migrate first.
2. Technical configuration and integrations
The agency configures pipelines, automations and tracking dashboards, then connects HubSpot to the rest of your IT system through turnK's Salesforce & HubSpot CRM integration offering: telephony, ERP, marketing platforms, without disrupting ongoing activity. Native AI agents such as Breeze can automate part of the administrative tasks from go-live.
3. Data migration and testing
Existing sales data is cleaned and then migrated in batches (active contacts and open opportunities first, history afterward) with systematic testing of automations before launch.
4. Training and sales adoption
The most often neglected step, even though it determines the return on investment: effective training starts from salespeople's concrete use cases, not from a generic demonstration of features.
Migrating your CRM to HubSpot without interrupting sales
For a sales director, the real risk of changing tools is not technical: it is the interruption of the pipeline in the middle of a target period, and the rejection of the tool by salespeople who are already under pressure.
Audit and mapping of existing data
Before any switchover, the agency sorts useful data from dead data: inactive contacts, duplicates, fields never filled in, to avoid importing the old CRM's mess into HubSpot.
Migrate in stages, with a dual-run period
By migrating in stages, with a dual-run period between the old and new CRM, the sales pipeline stays active throughout the switchover. This is the approach that allowed Horse Republic to migrate from Salesforce to HubSpot without losing the pipeline under negotiation.
Train only on the differences from the old tool
Short, targeted training on the real differences from the old tool overcomes the most frequent objection: the fear of wasting time relearning software. The agency keeps existing landmarks (pipeline, statuses, key fields) rather than imposing a complete overhaul.
4 project examples
These four cases cover very different sectors but all raise the same question: how do you make sure the CRM really serves salespeople, rather than becoming one more database.
Horse Republic: migrating without losing the pipeline in progress
In the sports sector, Horse Republic migrated its CRM from Salesforce to HubSpot with turnK, in stages and with data migration scoped upfront rather than a live cutover.
Histoires de Slides: aligning sales and project management
Histoires de Slides, a communication agency, integrated HubSpot to connect sales tracking and client project management, two activities too often handled with separate tools.
Café Joyeux: automating without losing customer proximity
Café Joyeux automated the tracking of its orders and indicators, freeing up time on repetitive tasks so teams could focus on the customer relationship.
Mirakl: synchronizing two CRMs to make data reliable
Mirakl called on turnK to synchronize HubSpot and Salesforce and reduce duplicates between the two systems, a common situation in fast-growing companies where different teams have adopted different tools over time.
HubSpot certification: what it guarantees, and what it does not
A HubSpot certification recognizes a free training path delivered by HubSpot Academy, followed by an online exam, for each building block of the platform (marketing, sales, customer service, content, data), generally valid for 12 to 24 months.
What it guarantees: a tested knowledge of the features and the inbound methodology on the relevant Hub.
What it does not guarantee: the ability to scope a project, to migrate your data cleanly, or to make sure your salespeople use the tool every day.
The certification is personal: it validates one person's knowledge at a given moment, not the working method of the whole agency. A firm can have a single certified consultant for several years and showcase them on every page, without the rest of the team working on your project having the same expertise.
Questions to ask before signing
How many certified consultants will actually work on your project, and on which Hubs? Can the agency cite projects similar to yours? How does it measure adoption after deployment, not just the technical go-live? Does it hold HubSpot Solutions Partner status, which assesses the agency as a whole rather than an individual consultant?
How to assess the ROI of HubSpot support
Doubt about return on investment is executives' main reservation before signing: the budget is committed immediately, while the value only materializes several months later. To make it objective, you need to measure what the project really changes in sales activity: time salespeople save on administrative tasks, forecast reliability, lead processing speed.
A runaway budget is rarely due to the agency's initial price: it most often comes from a poorly scoped project, repeated back-and-forth for lack of clear governance, or insufficient adoption that forces the configuration to be redone several months after launch.
How turnK structures its HubSpot projects
At turnK, the teams hold more than 98 Salesforce, HubSpot and Odoo certifications, earned on more than 600 projects carried out for SMEs and mid-sized companies, as well as groups such as Michelin. turnK's Salesforce & HubSpot CRM integration deploys in about 3 months instead of 6, with certification and adoption built together, not one without the other.

the most common questions
The budget depends on the scope: audit and scoping, implementation or migration, then long-term support. The HubSpot subscription, billed separately, comes on top. A scoping phase gives you a precise quote.
No, the agency's fees are separate from the HubSpot subscription, which is billed separately based on Hubs and number of users.
A well-scoped project usually takes around 3 months, versus 6 months for development run without a dedicated methodology. The duration depends on the complexity of the pipeline, the number of Hubs to activate and the volume of data to migrate. A project goes through four phases: audit and scoping, configuration and migration, integrations and automations, then training and adoption.
It depends on the volume of projects to run: an agency is often more cost-effective for a one-off project, an in-house hire for permanent CRM management.
