Streamline Your Financial Operations

Your accounting tool shouldn't require double entry. Integrating Wave with HubSpot ensures that the moment a sale is made, your finance records are updated accurately, eliminating copy-paste errors and saving hours of administrative work.

Automated Invoice Generation: Instantly create a draft or approved invoice in Wave populated with client details and line items when a HubSpot deal moves to "Closed Won."

Customer Synchronization: Automatically create or update customer profiles in Wave based on HubSpot Contact data, ensuring your billing information is always current.

Product Mapping: Map HubSpot Products to Wave Items to ensure that revenue is categorized correctly in your financial reports automatically.

Integrate IQ has consistently shown they can be trusted with even the most complex projects. I know our customers are in great hands and that the job will always get done right.

Gain Visibility into Cash Flow

Sales teams shouldn't have to ask finance if a client has paid. This integration pulls payment status back into the CRM, giving your revenue team a complete view of the customer lifecycle from lead to cash.

Payment Status Tracking: Sync the status of Wave invoices (e.g., "Sent," "Viewed," "Paid") back to the HubSpot Deal property, providing real-time visibility.

Automated Follow-ups: Trigger HubSpot email workflows when an invoice becomes overdue, automating collections without awkward manual emails.

Closed-Loop Reporting: Analyze true revenue in HubSpot by syncing actual billed amounts from Wave, ensuring your sales dashboards reflect reality.

Flexible, Robust Sync Architecture

Built for Your Business Process Standard connectors often force you to change your workflow to fit the tool. We take the opposite approach. We build the integration logic around your specific billing cycle and accounting rules, ensuring the sync facilitates your actual operations rather than hindering them2.

Built for Your Business Process

Standard, out-of-the-box connectors are built for simple, one-way data pushes. They can't handle the dynamic, tag-based segmentation or invoicing functions of Wave. We build your integration around your specific automations, mapping custom fields and product data bi-directionally.

Bi-Directional & Uni-Directional Sync:: We configure data to flow exactly how you need it, pushing closed deals to Wave for invoicing, and pulling payment statuses back to HubSpot for sales visibility.
Real-time & Scheduled Syncs:: For immediate invoicing, we utilize webhooks to trigger creation instantly. For reconciling payment statuses, we can deploy scheduled batches to respect API limits.
Custom Sync Logic & Triggers:: We don't just sync everything; we apply logic. For example, only sync deals from a specific pipeline or require a "Ready for Billing" property to be checked before creating an invoice.
High-Volume Data Handling:: Our architecture is designed to handle robust datasets, ensuring that even if you process hundreds of invoices a month, the sync runs reliably without timing out.

Comprehensive Object & Field Mapping

We map your CRM architecture directly to your accounting hierarchy.

Transparent, Project-Based Pricing

No surprises. Clear scope, clear acceptance tests. We believe in straightforward pricing so you know exactly what to expect before we begin.

A failed integration is more than a technical problem: it's a drain on time, budget, and morale. We are the specialists that leading companies like MetLife trust to handle their most mission-critical data flows. We don't rely on fragile connectors or simplistic platforms because we know they can't handle enterprise scale. Our approach is built on robust, custom development and a deep understanding of both HubSpot and the systems you need to connect it to. Partnering with us isn't just another attempt; it's an investment in certainty.

Why Integrate IQ?

Our four pillars for delivering successful outcomes on complex projects.

Mastery of Complexity

We thrive on custom API integrations, multi-system migrations, and “messy data” that makes others pause. Full support for standard and custom objects across your stack is table stakes for us.

Pragmatic Innovation

Real problems, shipped solutions. Our proprietary Smart Ramp apps were developed to fill gaps in HubSpot capabilities and solve real-world customer problems. The same practical mindset powers our HubSpot AI Accelerator: We focus on data readiness and shipped outcomes, not shiny features.

De-Risking the Process

Complex projects demand clarity. Our Smart Process runs on an 8-12 week cadence with stage gates, transparent deliverables, and clear pricing. That’s how we maintain a 98.5% customer retention rate.

The Expert You Call

We’re a developer-led team of integration engineers, solution architects, and technical PMs. Clients describe us simply: 'the folks you call when something seems impossible.'

I've been working with Integrate IQ for over 2 years now. We've had several outside systems that we wanted integrated with our HubSpot instance. From project planning and scoping, through build, and after deployment support, the team at Integrate IQ has been exemplary to work with. They've delivered on all commitments, helped established reasonable time frames for deliverables, and kept lines of communication open.

Marohn, M

We've partnered with Integrate IQ for over five years to develop integrations between our complex and not-so-widely-known ERP. They understand HubSpot's strengths, weaknesses and limitations, and are able to easily adapt to our evolving needs. They had an ownership change a few years ago, but that did not impact their expertise/service. We really appreciate our relationship with IIQ and recommend them to anyone looking to embed HubSpot deeper into their organization's systems.

Craychee, A

Integrate IQ has been great to work with! As someone who can be intimidated when things get too technical, they made the process of outlining our integration very approachable and understandable. They're great to work with and built the integration that we asked for, and then continued to work with us to fine-tune the tool over time as we figured out exactly what we needed.

Lauren Little

Integrate has been fantastic to work with. They helped us implement our CRM, design a framework for our pipeline that works perfectly and they built out an integration between HubSpot and Netsuite which allows our data to flow seamlessly. They've been an invaluable partner in our growth.

Whipple, M

We worked with Integrate IQ on a complex integration and now we have a fantastic solution that makes HubSpot work even better!

Off-the-Shelf Connectors vs Custom Integration Services

Native apps and iPaaS tools are the right call for simple syncs. Here's where they stop and custom engineering starts.

Frequently Asked Questions

Yes. We can map HubSpot properties (like "State" or "Tax Code") to specific Wave tax rates to ensure your invoices are generated with the correct compliance details.

Yes. If your HubSpot deal is in a foreign currency supported by Wave, we can map the currency code to ensure the invoice is generated in the correct denomination.

No. We implement deduplication logic based on email address or company domain. If the customer exists, we update them; if not, we create a new record.

This is a managed integration solution. We configure the API endpoints specifically for your workflow to ensure it handles your specific tax logic and product categories reliably.
