Custom HubSpot integrations, built for your stack.
When the marketplace connector does not exist, or exists but cannot carry your process, we design and build the integration: ERPs, billing platforms, data warehouses, legacy systems, and the middleware between them. Scoped before we build or quote, handed off with a runbook your team can own.
Six signals native cannot carry it.
Most teams need a native connector, configured well, and we will tell you when that is the answer. Custom earns its cost in six specific situations.
The app has no marketplace connector
Your billing platform, ERP, or internal tool is not in HubSpot's marketplace, or the listed connector covers a fraction of what you need synced.
Per-object mapping stops scaling
Native sync maps and maintains each custom object individually. With dozens of objects and bidirectional logic, the maintenance burden outgrows the connector.
You need real-time, not a sync cycle
Native connectors run on sync intervals. If your process needs sub-minute latency, activation triggers, instant routing, you need event-driven architecture.
Your dedupe rules do not fit either system
Households with linked accounts, government entities under one umbrella, multiple buying contacts per company. Matching logic this specific has to be built.
Multiple systems need one source of truth
When HubSpot, an ERP, and a data warehouse all hold overlapping records, someone has to own the normalized model. That is middleware, designed deliberately.
The connector exists but breaks your model
Some native connectors force a data model that fights how your business works. A custom build maps to your process instead of forcing you into theirs.
The systems we connect to HubSpot.
ERP platforms
NetSuite, SAP Business One, Odoo, Microsoft Dynamics. Orders, inventory, and fulfillment states flowing into the CRM your revenue teams actually work in.
Billing and finance
Stripe beyond the native connector, QuickBooks, Xero, custom invoicing systems. Subscription states, payment events, and revenue data wired to lifecycle stages.
Data warehouses
Snowflake, BigQuery, Redshift. HubSpot as a first-class source and destination in your data stack, with sync jobs your data team can monitor and own.
Legacy and internal tools
Homegrown databases, industry-specific software, systems that predate APIs. We build the connective layer, REST wrappers, scheduled jobs, or middleware, that brings them into the loop.
Middleware orchestration
Make, Workato, Tray.io, or purpose-built services. When three or more systems exchange data, middleware owns the normalized model and the business logic between them.
Event-driven and real-time
Webhook architectures for the workflows where minutes matter: product signups triggering instant sales routing, usage thresholds firing expansion plays.
Scoped first, built once, handed off clean.
Custom builds typically run 4 to 12 weeks depending on scope. Every engagement follows the same shape, and nothing is quoted before the audit.
Audit
Every system, object, field, and automation in scope, mapped to what the integration must accomplish. This is where we decide, with you, whether custom is even necessary.
Architecture
Data flow design, direction of truth per field, conflict rules, failure handling, and the middleware or API approach. Signed off by your team before any code is written.
Build and test
Built in a sandbox, dummy records flowing end to end, edge cases tested against real data shapes. Nothing touches production until it has survived staging.
Parallel run and cutover
Old and new paths run side by side until the numbers reconcile. Then cutover, monitoring, and a stabilization window with our engineers on call.
Runbook handoff
Documentation, monitoring, and a runbook your team can operate without us. Ongoing maintenance available, never required.
HubSpot Accreditations
Five partner-tier credentials HubSpot itself uses to vet implementation depth.
Already on the marketplace? Configure native instead.
If your app has a native connector, the smaller, faster engagement is configuring it properly. Start from the app page:
Asked on most scoping calls.
How much does a custom HubSpot integration cost?
It is scoped, not priced off a menu. Data volume, number of systems, custom objects, historical records, and latency requirements all shape the work, so quoting before the audit would be guessing. The scoping call is 30 minutes; if we are a fit, you get a fixed-fee proposal with the architecture summarized in plain language.
How long does a custom integration take?
Typical builds run 4 to 12 weeks end to end, depending on the number of systems and the complexity of the data model. The audit in week one produces a real timeline, not an estimate.
Do I need a custom integration, or will the native connector do?
Most teams need the native connector, configured properly. Custom is for the cases native cannot cover: no connector exists, per-object mapping has stopped scaling, you need real-time latency, or your matching logic does not fit either system. The audit gives you a direct answer; configuring native well is a smaller engagement and we will tell you if that is the right call.
Middleware or direct API, which do you build?
Both, chosen per case. Direct API connections suit two systems with stable, simple flows. Middleware (Make, Workato, or a purpose-built service) earns its place when three or more systems exchange data or when business logic lives between them. The architecture phase makes this call explicit, with trade-offs documented.
Who maintains the integration after launch?
Your team can. Every build ships with monitoring, documentation, and a runbook written for the people who will operate it. If you would rather we keep running it, ongoing maintenance is available as a retainer, but the handoff is designed so it is a choice, not a dependency.
What access do you need, and how is it handled?
Sandbox-first, always. We build and test against sandbox or staging environments with scoped credentials, and production access is limited to the cutover window with your team present. Credentials are never stored in code.
Can you fix or take over an integration someone else built?
Yes. Rescue work starts the same way as new builds: an audit of what exists, what breaks, and why. Sometimes the fix is surgical; sometimes the honest answer is a rebuild on cleaner architecture. You get that read before committing to either.
Tell us what the integration must accomplish.
A 30-minute scoping call to map your systems and the outcome. If we are a fit, a fixed-fee proposal follows, with the architecture in plain language.
