Custom HubSpot integrations, built and run by one certified engineer.
For a business whose data lives in an ERP, a billing system, and a spreadsheet nobody trusts anymore, and needs one of them to talk to HubSpot without breaking the other two. Several HubSpot Academy certifications, all verifiable, and a Reevia case with 2M+ records reconciled across four systems in four weeks.
Six kinds of HubSpot work
Order status, invoices, and inventory pulled into HubSpot from NetSuite, SAP, Dynamics, or QuickBooks, so reps stop asking finance which invoices are paid.
Connecting Your ERP to HubSpot ›Subscription status, payment history, and billing events synced into HubSpot, so support and sales work from the same numbers finance sees.
API Integration Guide: Stop Copying Data Between Your Systems ›A data model built for equipment, orders, subscriptions, or warranties, for when contacts, companies, deals, and tickets do not fit.
HubSpot Custom Objects: Do You Actually Need One? ›Events pushed to HubSpot the moment they happen elsewhere, instead of a batch job running once a night. Retries and signature checks built in.
Custom HubSpot Integration: The Complete Guide ›Several systems that have never agreed with each other, reconciled into one source of truth with a defined owner for every field.
When One HubSpot Account Cannot Trust Its Own Data ›Deduplication, normalization, and a review queue for weak matches, so a merge never happens silently and every value traces back to its source.

What happens after you write to me
You grant API access to HubSpot and the other system. I write down which system owns which field, before any code.
Real records moving between systems, in an environment that cannot touch your production data yet.
The sync runs unattended, on your real data, and you can watch it work.
I watch the sync, fix what breaks, and start mapping whatever system comes next.
Four systems, one source of truth.
HubSpot visibility for one of Brazil’s largest veterinary networks. 2M+ records reconciled across four systems that had never agreed with each other, in production in four weeks.
Read the Reevia case ›Answers before you write to me
What does a custom HubSpot integration cost?
HubSpot integration work sits inside Applications, one subscription at $7,999 a month. There is no separate quote, no hourly rate, and no setup fee. You get a full refund inside the first two weeks, and you can stop any month with no notice.
How long does a HubSpot integration take?
Timelines vary with how many systems are involved. Reevia's four systems reached production in four weeks. Inside the first month you get a plan in writing, then something running in staging with real data, then a first version ready to show.
Agency or one engineer?
One engineer, start to finish. I write every line myself, no middlemen, no account manager, and no handover between people who never spoke to each other. The person you write to is the person who writes the code.
How do you handle security and compliance?
Every value written to HubSpot carries its source and a timestamp, so any figure traces back in seconds. A weak match goes to a review queue instead of a silent merge. Terms include a standard NDA, and invoicing is IRS and IR35 safe.
When do I need a custom object?
When your data does not fit contacts, companies, deals, or tickets: equipment, orders, subscriptions, warranties. Custom objects need a HubSpot Enterprise plan and real setup work, so check whether a property or association solves it first.

HubSpot's data quality tools catch a lot, but they cannot fix a process that keeps feeding bad data in. This playbook covers the built-in tools, the habits that keep them working, and where integration design has to carry the rest.
You may already be tracking orders, equipment, or subscriptions in a spreadsheet next to HubSpot because it does not fit contacts or deals. Here is how to tell if that is a five-minute fix or a real build.
