Custom integrations

HubSpot connected to the tools your business actually runs on.

Your CRM is only as useful as the data that flows into it. We build custom integrations between HubSpot and your stack — with a defined data flow, a source of truth, and documentation someone else can maintain.

What we integrate

Common integrations we build and maintain

accounting-billing

Accounting & billing

Xero, QuickBooks, Chargebee, Stripe. Deal closed in HubSpot triggers invoice creation. Payment status syncs back to the contact record. No manual handoff between sales and finance.

booking-scheduling

Booking and scheduling

Calendly, Acuity, Microsoft Bookings. Bookings create or update HubSpot contacts automatically, log the meeting to the timeline, and trigger the right follow-up workflows.

erp-systems

ERP systems

SAP, Microsoft Dynamics 365, NetSuite. Customer records synced between HubSpot and your ERP with a clear source of truth — no duplicating data entry across two systems.

ecommerce-platforms

E-commerce platforms

Shopify, WooCommerce, Magento. Order data, product purchases and customer lifetime value flowing into HubSpot so your marketing team can segment and automate properly.

telephony-helpdesk

Telephony and helpdesk

Twilio, Aircall, Intercom, Zendesk. Calls and support tickets logged to the HubSpot contact timeline so your sales team has the full picture before picking up the phone.

databases-apis

Internal databases and APIs

Custom-built internal tools, proprietary databases, bespoke systems. If it has an API, we can connect it to HubSpot and define exactly what data flows where and when.

How we build integrations

Architecture first. Build second.

01

Define the data flow

Which system owns each record? What triggers a sync? What happens when the same record exists in both systems with conflicting data? We answer all of this before writing a line of code.

02

Map every field

Every field from your source system mapped to the right HubSpot property — including custom properties we create specifically for the integration.

03

Build and test

Built against a sandbox, tested with real data scenarios including edge cases, duplicate records and conflict resolution before going anywhere near production.

04

Document and hand over

Full technical documentation of what we built, how it works, and how to maintain or extend it. Someone else can pick this up without starting from scratch.

Before we build anything

Questions we always answer first

Which system is the source of truth?

For Contacts, for Companies, for Deals — which platform owns the record and which one follows? Getting this wrong at the start is the single biggest cause of integration failures six months later.

What is the sync direction?

Bidirectional syncs are powerful and dangerous. We define exactly what flows in each direction — and what should never be overwritten by the other system.

What happens on conflict?

A contact exists in both systems with different email addresses. Which one wins? We define conflict resolution rules before the integration goes live — not after your data has been overwritten.

Who owns it after it's built?

We build integrations with ongoing maintainability in mind. We also offer monitoring retainers for critical integrations — so if something breaks at 2am, we know before your team does.

Cost depends on the complexity of the data flow, the number of objects syncing and whether bidirectional sync is required. Includes architecture documentation.
