Reliable integrations
Connecting two systems is easy. Making sure it never fails is not.
An integration that works in the demo and duplicates customers the following month is worse than none at all. That’s why we design every HubSpot integration around what can go wrong: an API that’s down, a webhook that arrives twice, a change made in both systems at the same time.
Two-way sync with clear rules on which system owns each field. Idempotency: if an event arrives twice, the outcome is the same. Automatic retries when the other system doesn’t respond. Deduplication by IDs, not by names. And monitoring with alerts, so you know what failed before your team notices.
Every integration includes
- A flow document: what syncs, when and in which direction
- Signed webhooks and securely stored credentials
- Simulation mode (dry run) to test without touching real data
- A log of every operation and alerts on errors
- Technical documentation for your team

Why Vexco
Integrations built by people who understand the process
01
Business and code in the same team
The consultants who understand your sales and invoicing process are the ones who write the integration. Nothing gets lost between consultants and developers.
02
Tested against real cases
We define the acceptance tests with you before development. A payments integration for a law firm with 5 companies passed 90 out of 90 acceptance tests.
03
Custom-built when the connector falls short
If a native connector covers your case, we’ll tell you. If not, we build on the HubSpot API and the other system’s API, with no limits on fields or logic.
04
Compliance built in
We design with GDPR in mind and, for invoicing, Verifactu (Spain’s e-invoicing regulation). Personal data only travels where it needs to.
Method
How we build a HubSpot integration
Analysis
Flow map
We map which events trigger the integration, what data moves, in which direction and which system owns each field.
Design
Technical design
We choose webhooks, scheduled polling or both, define IDs to prevent duplicates and agree on the acceptance tests.
Development
Build and test
We build in sprints and test in simulation mode with real data, changing nothing until you sign it off.
Production
Go-live
We switch the integration on, load historical data if needed and set up logs and alerts to catch any error.
Problems we solve
Signs that you’re missing an integration
Finance re-types what sales has already closed.
When a deal is won, the customer and the invoice are created in the ERP with the quote’s line items, and the invoice number and PDF come back to HubSpot.
Sales doesn’t know whether the customer has paid.
We sync Stripe, SEPA or Redsys payments and the status of paid invoices onto the deal record.
Our online shop customers aren’t in the CRM.
We bring orders, returns and consent from Shopify or PrestaShop into HubSpot, with unified contacts.
WhatsApp conversations get lost on personal phones.
We log conversations on the contact record so the whole team can see the history.
We tried a connector and it filled our CRM with duplicates.
We use unique IDs and idempotency: even if an event arrives twice, the record is only created once.
The integration fails and nobody notices.
Every operation is logged, errors are retried automatically and, if they persist, you get an alert.

What clients ask us before we start
Which systems can HubSpot be integrated with?
Any system with an API or that allows automatic data exchange. We’ve integrated HubSpot with Holded, Odoo, Stripe, Redsys, Shopify, PrestaShop, Klaviyo, WhatsApp, Zendesk, Google Calendar, property portals and CLM platforms such as Ironclad, among others.
How much does a HubSpot integration cost?
It depends on the number of flows, whether the sync is one-way or two-way, the quality of the other system’s API, the volume of historical data and the business rules. Once we’ve analysed your flows, we give you a fixed-price quote.
How long does it take to build an integration?
An integration with a single, well-defined flow can be done in a few weeks. Those connecting several systems or several companies are part of projects that can run to 10-14 weeks. We give you the exact timeline in the proposal.
Is a marketplace connector or a custom integration better?
If an existing connector covers your case, it’s the fastest option and we’ll recommend it. A custom integration makes sense when you need your own logic, custom fields or objects, several companies, or control over errors and duplicates.
What happens if the other system’s API fails?
The integration automatically retries failed operations, logs every attempt and, if the error persists, alerts your team or ours. Because operations are idempotent, retries don’t create duplicates.
Who maintains the integration afterwards?
We hand over the technical documentation and the code. If you prefer, we maintain and monitor it as part of our monthly support, including API version changes.
