8 Best Tools to Integrate With HubSpot (2026)
Your sales data lives in one system. Marketing runs from another. Finance has its own set of numbers. If those tools are not connected to your CRM, every team is making decisions with an incomplete picture. For revenue and marketing operations teams running HubSpot, this disconnect creates reporting gaps, duplicated effort, and slower deal cycles.
WeSimplifi helps businesses connect their most critical tools to HubSpot so that sales, marketing, and service teams operate from a single source of truth. This guide breaks down the business tools that most commonly need HubSpot integration, why each connection matters, and how to evaluate which ones belong in your stack.

- WeSimplifi Systems Integration: The best HubSpot integration partner for connecting your entire tech stack under one unified CRM strategy.
- Slack: Real-time deal and lead notifications posted directly to team channels.
- QuickBooks Online: Accounting data synced with CRM records for revenue reporting.

How we chose the best tools to integrate with HubSpot
Choosing which tools to connect first is not just about availability on the HubSpot App Marketplace. The integrations in this guide were selected based on how directly they solve the data and workflow problems that RevOps and marketing operations teams face every day.
- Data flow impact: Does the integration eliminate a data silo that causes reporting blind spots or duplicated records? You need every customer interaction visible in one place.
- Workflow automation potential: Can the connection trigger automated actions, such as deal updates, task creation, or lead routing, that save your team hours of repetitive work each week?
- Cross-team alignment: Does it give sales, marketing, and service teams a shared view of the same customer data, so handoffs between departments are reliable?
- Revenue attribution clarity: Can the integration trace closed deals back to specific campaigns, channels, or touchpoints so you can report on what is actually driving pipeline?
- Scalability: Will the connection handle growing data volumes and more complex workflows without requiring a rebuild as your business scales?
- Implementation complexity: Is the integration something your ops team can configure through native connectors, or does it require middleware and custom development?
The 8 best tools to integrate with HubSpot for unified data
1. WeSimplifi Systems Integration: Best overall for connecting your HubSpot tech stack
When you are running multiple business systems alongside HubSpot, the challenge is not just connecting them. It is making sure data flows accurately, in the right direction, and supports your actual business processes. WeSimplifi specialises in building these connections for mid-market and scaling businesses that need more than a basic marketplace connector.
As a certified HubSpot Platinum Partner, WeSimplifi connects HubSpot with ERPs, finance platforms, and custom applications to create a single source of truth. The approach starts with mapping your existing data flows and identifying where gaps, duplicates, or sync conflicts exist before any technical work begins.
WeSimplifi builds custom integrations using webhooks, Make.com, and HubSpot's API to handle scenarios that native connectors cannot support. One client with over 1,000 SKUs across nine product categories needed dynamic pricing linked to deal records. WeSimplifi built a custom automation that connected their pricing logic directly to HubSpot, enabling accurate revenue reporting without any manual data entry.
WeSimplifi Systems Integration features
- Custom data mapping: Every integration starts with a detailed audit of your existing systems. WeSimplifi maps fields, sync directions, and ownership rules so your data arrives clean and in the correct format.
- ERP-to-HubSpot connectivity: Whether you run SAP, NetSuite, QuickBooks, or a legacy system, WeSimplifi connects ERP data directly into HubSpot so that sales, service, and marketing share one account view.
- Workflow automation: Post-integration, WeSimplifi configures HubSpot workflows that trigger actions based on synced data, such as creating tasks when an invoice status changes or routing leads based on enriched company data.
- Ongoing support through GrowthHub: After go-live, WeSimplifi's GrowthHub retainer provides continuous optimisation, quarterly reviews, and support hours so your integrations keep performing as your business evolves.
- Deduplication and data governance: Every project includes rules for preventing duplicate records, handling field conflicts, and maintaining data hygiene across connected systems.
WeSimplifi Systems Integration pros and cons
| Pros | Cons |
|---|---|
| Certified HubSpot Platinum Partner with deep platform expertise across all Hubs | Primarily focused on HubSpot, so businesses using a different CRM as their primary platform would need a HubSpot-centric approach |
| Handles complex, non-standard integrations including legacy ERPs and custom APIs | Custom integration projects require a discovery phase before development begins |
| Includes post-launch support and quarterly optimisation through GrowthHub | Currently headquartered in the UK, though they serve clients across time zones |
2. Slack: Team notifications synced with CRM activity
Slack's HubSpot integration posts deal stage changes, form submissions, and lead assignments directly into designated channels. Your sales and marketing teams can see CRM activity without switching tabs or logging into HubSpot.
The integration also supports creating HubSpot tasks, notes, and deal updates from within Slack. For RevOps teams managing handoffs between departments, this keeps everyone aligned on the same pipeline activity in real time.
Slack features
- Channel-based CRM alerts: Configure which deal events, form fills, or lifecycle changes post to specific Slack channels, keeping notifications relevant to each team.
- In-Slack CRM actions: Create tasks, add notes, or update deal stages without leaving Slack, reducing context switching for reps working across tools.
- Workflow triggers: Use HubSpot workflows to send conditional Slack messages, for example alerting a sales manager when a deal above a certain value moves to a new stage.
Slack pros and cons
| Pros | Cons |
|---|---|
| Native HubSpot integration with straightforward configuration | Notification fatigue can occur without careful channel and trigger setup |
| Enables CRM actions directly from Slack without platform switching | Advanced workflow-triggered messages require HubSpot Professional or Enterprise plans |
| Widely adopted, so most teams can start using it immediately | Slack's free plan limits message history, which may affect teams relying on it for CRM audit trails |
3. QuickBooks Online: Finance data connected to CRM reporting
QuickBooks Online syncs invoices, payments, and customer records with HubSpot. For finance and RevOps teams, this connection means you can see payment status alongside deal data without checking two separate systems.
The native HubSpot integration syncs contacts, companies, and invoices. However, it does not automatically link invoices created in QuickBooks to deals in HubSpot. Businesses that need this deal-level reporting typically require a custom integration to bridge that gap.
QuickBooks Online features
- Invoice sync: Invoices created in either platform appear in both systems, giving sales and finance a shared view of billing status.
- Contact and company matching: QuickBooks customer records map to HubSpot contacts and companies, reducing duplicate data entry across teams.
- Payment status visibility: Sales reps can see whether an invoice has been paid directly on the HubSpot contact or company record.
QuickBooks Online pros and cons
| Pros | Cons |
|---|---|
| Native HubSpot integration available through the App Marketplace | Does not link invoices to deals natively, limiting revenue attribution at the deal level |
| Syncs contacts, companies, and invoices between both platforms | Two-way sync is limited to specific object types and fields |
| Reduces manual data entry for finance and sales teams | Custom field mapping for non-standard invoice data requires additional configuration |
4. Gmail and Outlook: Email activity logged automatically
Gmail and Outlook integrations log sent and received emails directly to HubSpot contact records. This gives managers and reps a complete communication history without relying on anyone to remember to update the CRM.
Both integrations also sync calendars and enable email tracking, so your team can see when a prospect opens an email or clicks a link. For marketing operations teams, this data feeds into lead scoring models and lifecycle stage automation.
Gmail and Outlook features
- Automatic email logging: Every email sent or received is recorded on the relevant HubSpot contact timeline.
- Calendar sync: Meeting bookings sync with HubSpot, creating associated records and triggering follow-up workflows.
- Email tracking: Open and click notifications help sales reps time their follow-ups based on prospect engagement.
Gmail and Outlook pros and cons
| Pros | Cons |
|---|---|
| Available on HubSpot's free plan with no additional cost | Email tracking notifications can be blocked by some email clients or privacy settings |
| Automatic logging removes reliance on reps manually updating CRM records | Shared mailboxes require additional configuration to log correctly |
| Calendar sync supports meeting-based workflows and lead routing | Advanced features like sequences and templates need Sales Hub Starter or above |
5. Calendly: Scheduling linked to CRM records and workflows
Calendly's HubSpot integration creates or updates contact records when someone books a meeting. It also triggers workflows based on meeting type, making it useful for routing leads to the right sales rep or launching nurture sequences.
For teams managing inbound demo requests or consultation bookings, this connection removes the gap between a prospect scheduling a call and that activity appearing in HubSpot. Every booking feeds directly into your pipeline without manual entry.
Calendly features
- Automatic contact creation: New bookings create HubSpot contacts with event details attached, so reps have context before the call.
- Workflow triggers: Meeting bookings can start HubSpot workflows, such as sending a pre-call email or assigning a follow-up task.
- Event-type routing: Different Calendly event types can map to different pipelines or deal stages in HubSpot.
Calendly pros and cons
| Pros | Cons |
|---|---|
| Creates and updates HubSpot records automatically from bookings | HubSpot offers its own native meetings tool, which may overlap for some use cases |
| Supports workflow triggers based on event type for lead routing | Advanced routing and round-robin features require Calendly's paid plans |
| Widely recognised scheduling tool with high prospect adoption | Custom field mapping between Calendly and HubSpot requires setup for non-standard data |
6. LinkedIn Sales Navigator: Prospect data enriched with CRM context
LinkedIn Sales Navigator integrates with HubSpot to sync lead and account data. Sales reps can see HubSpot CRM information directly within LinkedIn, and InMail activity logs back to the contact record.
For outbound sales teams, this connection enriches prospect profiles with company data, job changes, and shared connections. It helps reps prioritise outreach based on CRM data rather than relying on LinkedIn alone.
LinkedIn Sales Navigator features
- CRM sync: Lead and account data syncs between LinkedIn Sales Navigator and HubSpot, keeping both platforms current.
- InMail logging: Messages sent through LinkedIn are recorded on the HubSpot contact timeline for a complete outreach history.
- Lead recommendations: Sales Navigator suggests leads based on your saved preferences and existing HubSpot data.
LinkedIn Sales Navigator pros and cons
| Pros | Cons |
|---|---|
| Enriches HubSpot contact records with LinkedIn profile data | Requires a Sales Navigator subscription, which is a separate cost |
| InMail activity logs to HubSpot for a unified outreach timeline | Sync is limited to specific fields and does not transfer full LinkedIn activity |
| Helps reps prioritise leads using CRM and LinkedIn data together | Initial setup requires admin access to both platforms and field mapping |
7. Google Ads: Campaign data tied to closed revenue
Google Ads integrates with HubSpot to sync campaign performance data with CRM records. This means your marketing team can attribute closed deals back to specific ad campaigns and keywords, rather than reporting on clicks and impressions alone.
The integration supports audience syncing, so you can build HubSpot lists and push them to Google Ads as custom audiences. For marketing operations teams running paid acquisition, this closes the loop between ad spend and actual revenue.
Google Ads features
- Closed-loop attribution: Track which ad campaigns and keywords generate deals, not just leads, giving your team accurate ROI reporting.
- Audience sync: Push HubSpot contact lists to Google Ads as custom audiences for targeted remarketing campaigns.
- Ad performance in CRM: View ad interaction data on contact records, showing which campaigns influenced a prospect's journey.
Google Ads pros and cons
| Pros | Cons |
|---|---|
| Native integration with closed-loop revenue attribution | Full attribution reporting requires HubSpot Marketing Hub Professional or above |
| Audience sync enables CRM-powered ad targeting | Attribution models vary, and multi-touch reporting may require additional configuration |
| Ad performance data visible directly on contact records | Google Ads data granularity depends on how campaigns and UTM parameters are structured |
8. ERP platforms (SAP, NetSuite, custom): Operational data unified with CRM
ERP systems hold order history, inventory levels, pricing configurations, and financial data that sales and service teams need to serve customers effectively. Connecting your ERP to HubSpot gives every customer-facing team access to this operational data without requiring them to log into a separate system.
These integrations typically require middleware or custom development, as most ERPs do not have a native HubSpot connector that handles bidirectional data sync for custom objects. The complexity depends on your ERP's architecture and the specific data points you need to surface in HubSpot.
ERP integration features
- Order and invoice visibility: Sales reps can view a customer's order history and invoice status directly on the HubSpot company or deal record.
- Inventory-aware selling: Real-time stock data synced to HubSpot helps reps avoid quoting products that are out of stock or on back-order.
- Custom object sync: ERP data that does not fit standard HubSpot objects (like shipment records or service contracts) can be mapped to custom objects for full visibility.
ERP platforms pros and cons
| Pros | Cons |
|---|---|
| Gives customer-facing teams access to operational data without a separate system | Requires custom development or middleware for most ERP connections |
| Supports complex data sync including custom objects and bidirectional flows | Implementation timelines are longer compared to native HubSpot marketplace integrations |
| Connects financial and operational data to CRM for more accurate forecasting | Ongoing maintenance is needed to handle API changes and schema updates on the ERP side |

How do you decide which HubSpot integrations to prioritise?
Start by identifying where your team loses the most time to manual data entry or context switching. If sales reps are copying invoice numbers from your accounting platform into HubSpot deal records, that is a clear sign your finance integration should be high on the list.
Next, map your reporting gaps. If you cannot trace a closed deal back to the marketing campaign that generated the lead, your ad platform integration is a priority. According to Gartner's 2024 iPaaS Market Share Analysis, the integration platform market grew 23.4% to $8.5 billion, reflecting the urgency businesses place on connecting their tools.
Finally, consider your team's technical capacity. Native HubSpot connectors can be set up in minutes, while ERP or custom integrations may require a partner like WeSimplifi to handle field mapping, sync logic, and data governance.
What are the risks of poorly planned HubSpot integrations?
The most common failure is not a broken connector. It is unclear data ownership. When multiple systems write to the same HubSpot fields without defined rules, you end up with conflicting records, overwritten properties, and reports that nobody trusts.
Duplicate records are another frequent issue. Connecting a tool that creates new contacts (like a scheduling or form platform) without deduplication rules leads to a bloated database. Over time, this affects email deliverability, list accuracy, and segmentation quality. According to HubSpot's marketing operations research, many teams use less than half of their installed marketing technology tools, making regular audits essential.
The third risk is sync lag. Some integrations use timed polling rather than event-driven sync. If your team relies on real-time data for lead routing or deal stage automation, a five-minute delay can mean a missed follow-up window. Understanding whether an integration uses webhooks or scheduled polling helps you set the right expectations for your workflows.

FAQs about HubSpot integration tools
What is a HubSpot integration?
A HubSpot integration connects HubSpot with another business tool so that data, records, and workflow triggers flow between both systems automatically. WeSimplifi builds these connections so your CRM becomes the single source of truth for every customer-facing team.
How many integrations does HubSpot support?
HubSpot's App Marketplace lists over 2,000 integrations across sales, marketing, service, and operations categories. WeSimplifi helps businesses identify which of these connections will deliver measurable results rather than adding unnecessary complexity.
Do I need a partner for HubSpot integration?
Native marketplace integrations can often be set up by your ops team. However, custom connections to ERPs, finance platforms, or legacy systems require field mapping, sync logic, and ongoing governance that a specialist like WeSimplifi provides.
What is the difference between native and custom HubSpot integrations?
Native integrations are pre-built connectors available in the HubSpot App Marketplace. Custom integrations are purpose-built connections that WeSimplifi develops using HubSpot's API, webhooks, and middleware platforms to handle data flows that native connectors do not support.
How long does a HubSpot integration take?
Simple native integrations take minutes to configure. Complex custom integrations, such as connecting an ERP to HubSpot with bidirectional data sync and custom object mapping, typically take two to six weeks including discovery, build, testing, and launch.
