Custom vs. Packaged Integrations: What’s the Difference?

Our Process

How We Tackle Custom Projects

We approach integrations as a guided, collaborative effort with support from start to post-launch. This involves four steps.

01. Discovery

In a dedicated kick-off call, we’ll get to know your company and meet your team. We will discuss:

  • Your system of choice
  • Customization options
  • Point of contact
  • General timeline 

02. Build

Once we’re ready, we develop everything we’ve scoped in our previous meetings. We will:

  • Build your sync logic
  • Create your field mapping
  • Begin custom development 
  • Work on anything else requested

03. Test & Launch

After we process test data and sync flows, we’ll start launching your integration. Our team will:

  • Populate historical data
  • Review data
  • Provide training
  • Ensure everything is synced properly

04. Support

Just because your data is flowing between both systems, doesn’t mean we say goodbye. We will: 

  • Monitor your integration
  • Provide troubleshooting
  • Make recommendations
  • Offer updates or changes

Insights & Resources


Need an Answer Now?

Take a look at some of the most common questions we get about custom integrations.
What fields should I map between my CRM and HubSpot?

Field mapping involves aligning a field from your CRM to a field in HubSpot. Seeing as there are different fields across different CRMs, many people wonder what fields they should focus on during their integration. We suggest mapping any custom fields you want or need, any fields that help build marketing lists, and any fields that could help sales in their roles.

How long will a custom integration take?

While there are variables that will impact your timeline, our integration team at Lynton sees an average custom HubSpot integration take 90 days to complete.

Do I need a developer on my team?

While it may be helpful to have a developer, it is not necessary with our integration offerings. Lynton’s HubSpot integrations require no IT experience.

What is Data Sync?

Data Sync from HubSpot offers packaged integrations that provide bidirectional syncing of contact and company data from HubSpot’s most used and requested integrations, such as Dynamics or Zendesk. These integrations may work for some companies but do not allow for customized sync logic or field mappings.
