HubSpot Bogging NetSuite Processes Down

JStephens22 — Mon, 22 Dec 2025 18:06:12 GMT

Hello -

We are using the HubSpot Synch Bundle in NetSuite which works great except that NetSuite is reporting that HubSpot is bogging the NetSuite down. We turned off the synch and only turn it on 20 minutes once a day to reconcile records. But NetSuite is still reporting synching with errors from HubSpot even though the synch is off. This is reporting multiple times a day.

Help logs say there are scripts running regardless of synch. So, we will turn off the scripts to see if that makes a difference NetSuite performance.

Has anyone had similar experiences? If so, how did you resolve this to not bog NetSuite down? When NetSuite indicates errors during synch, does that mean there are record errors that need to be fixed?

Thanks!

Hi @JStephens22,

Thank you for reaching out to the Community!

Since this involves specific behavior regarding the HubSpot Sync Bundle and NetSuite scripts, I want to first loop in a few of our top contributors who have deep experience with integrations to see if they have encountered this specific performance "bogging" or the persistent error logs.

@RubenBurdin, @Mike_Eastwood - have either of you seen instances where the sync scripts continue to report errors even after the sync is paused?

To help us dig into this further, would you be able to share:

- Specific error codes or messages appearing in the NetSuite logs?

- Are the errors referencing a specific record type (e.g., Contacts vs. Companies)?

Thanks for sharing these details—it will help the community get you the right information to move forward!

This sounds like a really challenging performance issue and you are right to be concerned about NetSuite getting bogged down. The fact that you are still seeing sync errors even after turning off the sync is a clear sign that there are background scripts or scheduled processes still running that are hitting NetSuite's APIs.

Here is what is likely happening:

The HubSpot Sync Bundle for NetSuite uses scheduled scripts that run in the background to keep data in sync. Even when you disable the main sync toggle, some of these scheduled scripts may still be active and trying to execute. NetSuite tracks all script execution and API calls, so if those scripts are still queued or running on a schedule, they will continue to consume governance units and processing resources.

The errors you are seeing during sync attempts usually mean one of two things. First, there could be record-level issues where specific records in HubSpot or NetSuite have data that does not meet validation rules or field mapping requirements. Second, the scripts themselves might be timing out or hitting governance limits because they are processing too many records at once.

Here is what I recommend you do to resolve this:

First, go into NetSuite and check the Scheduled Script Status page under Customization > Scripting > Scheduled Scripts. Look for any HubSpot-related scripts that are still marked as active or have queued executions. You need to disable these completely, not just pause the sync from the HubSpot side.

Second, review the Script Execution Log in NetSuite under Customization > Scripting > Script Execution Log. Filter by HubSpot scripts and look at the specific error messages. This will tell you exactly which records are failing and why. Common issues include missing required fields, invalid data formats, or permission problems.

Third, check your sync settings in the HubSpot Sync Bundle configuration. Make sure you have set reasonable batch sizes and frequency limits. If you are syncing thousands of records multiple times per day, that will absolutely bog down NetSuite. Consider reducing the batch size to 50-100 records at a time and spacing out sync intervals.

Fourth, look at your field mappings. If you have custom fields or complex formulas mapped between HubSpot and NetSuite, those can cause significant processing overhead. Simplify where possible and only sync the fields you actually need.

Regarding your question about errors during sync, yes, those typically indicate data issues that need to be fixed. The errors could be on either the HubSpot side or the NetSuite side. You need to identify which specific records are failing and fix the underlying data problems. Otherwise, the scripts will keep retrying those failed records and consuming resources.

One more thing to check is whether you have any workflows or custom scripts in NetSuite that are triggered by record updates from HubSpot. If HubSpot is updating a record and that triggers a heavy workflow or another script, you can end up with cascading performance issues.

Turning off the scripts like you mentioned is a good troubleshooting step. If NetSuite performance improves after disabling the HubSpot scripts, that confirms the sync bundle is the culprit. You can then turn the scripts back on one at a time with reduced frequency and batch sizes to find the right balance.

If you need help reviewing the specific error logs or optimizing your sync configuration, feel free to share the error details here and I can provide more targeted guidance.

Disable all HubSpot scheduled scripts in NetSuite, fix any data errors, reduce batch sizes, and space out sync intervals to prevent performance issues.

Hey @JStephens22,
This is unfortunately a common pain point with the HubSpot Sync Bundle for NetSuite. @amjadkhatri covered the diagnostic steps well, but I want to add some context on why this happens and what your options are.
The root issue is architectural. The Sync Bundle runs SuiteScripts inside NetSuite which consume governance units on every execution. Even "turning off" the sync from HubSpot's side doesnt necessarily stop the scheduled scripts that are already deployed in NetSuite. Those scripts wake up on their schedule, check for work, and consume resources even if theres nothing to sync. When there are errors, they retry repeatedly which compounds the problem.
To properly disable everything, you need to go to Customization > Scripting > Script Deployments in NetSuite (not just Scheduled Scripts) and set the HubSpot related deployments to "Not Scheduled" or "Testing" status. Thats the only way to fully stop them from executing.
Regarding the errors, yes they typically mean record validation failures. Common culprits include missing required fields on NetSuite records, customer/contact associations that dont exist, or currency mismatches. Check the Script Execution Log filtered by the HubSpot bundle scripts and look at the "Details" column for specifics.
That said, even with perfect data, the fundamental problem is that bundle based integrations put load directly on NetSuite's scripting engine. If you're syncing significant volumes or need frequent updates, you'll keep hitting governance ceilings.
At Stacksync we've worked with several teams who hit exactly this wall with the native HubSpot NetSuite sync. Our approach doesnt run scripts inside NetSuite, so it doesnt compete for governance units or bog down your ERP. Might be worth exploring if tuning the bundle doesnt get you where you need to be.

Happy to hear what you find in the logs!
