Track Campaign Delivery with the HubSpot Harvest Integration

By connecting HubSpot with a project and time-tracking tool like Harvest, you get a more accurate picture of performance and resource use. Using timesheets and forecasts, you can understand how many hours are being used for campaign or lead management. This makes it easier to work out the actual cost versus return.

There’s no native HubSpot Harvest integration, but the benefits are well worth the effort and investment of a custom integration.

Harvest is a simple yet powerful time-tracking and project management tool. Many marketing teams use it to log hours, manage deliverables, and report on time spent across campaigns. HubSpot, on the other hand, is your go-to for marketing automation, lead management, and reporting.

When we talk about integrating HubSpot and Harvest, we’re referring to a tailored connection that syncs the two platforms. This allows you to track campaign-related tasks and time entries in Harvest, then reflect those insights into HubSpot, creating a single source of truth for marketing efficiency.

Done properly, the integration aligns your campaign activities, resources, and reporting, helping you:

• Understand the real-time cost of marketing campaigns

• Prove ROI with accurate, effort-based reporting

• Improve project planning and forecasting

• Strengthen sales and marketing collaboration

1. Unlock ROI visibility

One of the biggest challenges for marketing leaders is showing return on investment in a way that resonates with finance and leadership. Tracking advertising spend is one thing, but what about internal hours? If your team spends 40 hours building an automation workflow that generates 20 leads, how does that compare to a campaign that took five hours and generated ten?

By syncing Harvest with HubSpot, you can track time spent on specific campaigns, associate that with performance data, and report on the cost per lead or opportunity based on real effort.

2. Improve productivity & planning

Without an integrated system, it’s common for time logs and campaign data to live in silos. This creates a manual workload just to reconcile the two, and leaves room for misalignment and overestimated ROI.

Bringing HubSpot and Harvest together means your team can:

• Reduce duplication of effort

• Better allocate time based on past campaign data

• Flag resource-intensive projects early

The result is a more productive team that spends less time entering numbers and more time delivering meaningful work.

3. Strengthen sales & marketing alignment

Marketing operations go hand-in-hand with sales enablement. If your team is producing sales collateral, product launch support, or nurture content, it’s important to understand how long these efforts take and whether they’re delivering impact.

With HubSpot Harvest integration, marketing and sales teams can align more easily on shared workloads. For example:

• A Harvest task marked ‘complete’ can trigger a follow-up task in HubSpot

• HubSpot campaign results can inform which projects to prioritise in Harvest

You have a smarter way to work across functions and deliver joined-up reporting.

To give a clearer picture of how this works in practice, here are a few real-world scenarios where the HubSpot Harvest integration delivers value:

Campaign resourcing

Let’s say you’re planning a webinar series. By logging time in Harvest and syncing it to the relevant HubSpot campaign, you can measure total hours spent on:

• Planning and promotion

• Presentation creation

• Follow-up communications

This allows you to benchmark future webinars, forecast resourcing needs, and justify resource investment based on results.

Reporting on internal vs external work

For marketing teams supporting both internal and client-facing work, the integration enables you to segment time entries accordingly and view results in context.

Lead-to-project workflow

When a new lead reaches a certain stage in HubSpot, you can create a project in Harvest that dictates how this impacts team resourcing, for example, when a sales-qualified lead becomes a customer. With a custom integration, we can set this up to happen automatically, saving time and ensuring smooth handovers.

This isn’t a standard plug-in or out-of-the-box app. To ensure the integration works seamlessly and meets your specific needs, we follow a custom process. Here’s what that looks like:

1. Discovery & scoping

We start by understanding your current processes: how you use HubSpot and Harvest, and what success looks like. This step ensures we design an integration that meets your needs.

2. Solution design

Once we know your requirements, we map out how data should flow between the platforms. This includes defining which activities in Harvest should be linked to which objects or campaigns in HubSpot, and whether we need to create custom objects.

3. Custom integration

We use the HubSpot and Harvest APIs to build a secure, scalable integration tailored to your business. Every connection is set up with long-term reliability and data integrity in mind.

4. Testing & validation

Before going live, we rigorously test the setup to make sure time entries, task updates, and campaign links all work as expected. Any edge cases or complex scenarios are ironed out here.

5. Training & support

We provide handover documentation and, if needed, team training. Our goal is to make the integration as intuitive and useful as possible for day-to-day users. Beyond integration, we can continue to support with ongoing optimisations and technical consulting.

Once the HubSpot Harvest integration is in place, it’s important to track the benefits. These are some of the common indicators of success:

• Time saved on manual reporting and data reconciliation

• Greater confidence in ROI reporting to senior stakeholders

• Improved campaign forecasting using historic time and effort data

• More effective planning and allocation of internal resources

• Stronger collaboration between marketing and sales teams

If you’re spending time trying to prove the value of your marketing activities, manage resourcing, or align with sales, the HubSpot Harvest integration can make a meaningful difference. But only when it’s implemented well.

At MarCloud, we manage the end-to-end setup so you don’t have to worry about technical hurdles. We design integrations that work the way you do, so you can focus on delivering creative campaigns and demonstrating impact.
