HubSpot Custom Integration
Your systems, joinedto your CRM
We connect HubSpot to the systems it does not reach by itself, such as your own product, an ERP or an internal database, so sales and service work from current facts.
What we build
01Objects mapped
02Limits respected
03Deals to orders
HubSpot is where your team talks to customers, so it should already know what those customers use, owe and ordered.

HubSpot custom integration links your HubSpot account to software that has no ready connector, or whose connector does too little. Typical cases are product usage from your own application, orders and invoices from an ERP, or records from an industry system. We build on HubSpot's CRM APIs, webhooks and batch endpoints, with a service that maps objects, respects rate limits and queues what cannot be delivered.
It suits teams whose representatives switch screens to answer simple questions, whose quotes are retyped into an ERP after a deal closes or whose lifecycle emails need data HubSpot never receives. The modelling matters more than the plumbing. Deciding whether an order is a deal, a custom object or a property on the company determines which reports and automations your team can build afterwards.

What It Looks Like When It Ships
From Kickoff to Launch
With sales operations we decide how external records should appear in HubSpot, which objects and associations to use and which reports and workflows the result has to support.
For every property we record which system may change it, how conflicts are resolved and what happens when a record is merged or deleted on either side.
The service is developed against a HubSpot test account and a test copy of your system, including a backfill, bursts of volume and deliberately broken records.
Read-only data appears in HubSpot first. Writes back to your system follow once the team trusts the figures, and workflows that depend on them are switched on last.
Built for Teams Like Yours
What buyers ask before they start
If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.
Book a callAn account administrator must authorize the integration and choose its scopes. API allowances vary by subscription tier, and some features, including custom objects, are limited to higher tiers. HubSpot has also been changing how in-account integrations are created and authenticated, so we check its current developer documentation at the start of each project and use the method it recommends at that time.
Yes, and it is one of the most useful flows. When a deal reaches an agreed stage, the integration validates it, creates the customer if needed and creates the order with its line items in the ERP. The order number, delivery status and invoice state then return to the deal. Products and prices are synchronized from the ERP so that quotes use valid items.
When it already moves the objects you care about in the direction you need. Connectors are quick to install and maintained by someone else. We recommend one whenever it fits. Custom work makes sense when the connector ignores custom objects, cannot express your ownership rules, syncs too slowly or does not exist at all, which is usual for software you built yourselves.
By design instead of by luck. Changes are grouped into batch calls, non-urgent updates are spread through the day and search requests, which have a stricter limit, are kept to a minimum by storing identifiers. The service reads the limit information HubSpot returns and slows itself before a refusal. A dashboard shows consumption, so a new workflow that doubles traffic is noticed early.
It depends on what you want to do with it. A property is simplest and works for a single value such as plan or last login. A custom object suits things a company has many of, like subscriptions or shipments, and supports its own pipelines and reports. Deals fit revenue you forecast. We test the options against the reports and workflows you actually need.
