Engineering a Unified CPQ Layer to Bridge ConnectWise MSP and eLation ISP Catalogs

Native CRM syncing couldn't pass MSP CPQ line items. That was true for a $500M+ telecom provider.

We engineered a custom API callback layer. It bridges ConnectWise and eLation ERP catalogs and injects unified product data into HubSpot Deals. That sped up the quote-to-cash cycle and cut out manual double-entry.

Executive Summary

Context

A $500M+ telecom provider sells both ISP and MSP services. It couldn't generate unified quotes, because its product data lived in two incompatible systems: eLation and ConnectWise.

What We Built

We built a custom API callback layer that bridges ConnectWise CPQ and HubSpot. It automates line-item injection for unified quoting.

Tech Stack

ConnectWise, eLation ERP, HubSpot Sales Enterprise, Custom API Layer (Node.js/Make).

Not a fit for organizations with simple, single-catalog product lists or those not already using ConnectWise as their MSP source of truth.

The Challenge

The sales team was operating at half-speed. Because the provider sells ISP fiber (managed in eLation) alongside MSP hardware (managed in ConnectWise), no single system held the complete "price" of a customer. Standard HubSpot DataSync mapped the Opportunities, but the line items stayed locked in the ConnectWise vault. This forced reps to generate two separate quotes or manually copy-paste SKUs, leading to frequent pricing errors and a disjointed customer experience. We tried the native sync; it simply wasn't built for the granularity an MSP requires.

Our Approach

We stopped trying to force the native sync to do something it wasn't designed for. Instead, we architected an event-driven callback system. A specific HubSpot Deal Stage, "MSP Ready for Quote", became the trigger. When a deal hits that stage, our API layer creates the corresponding Opportunity in ConnectWise. The rep adds the hardware and services in ConnectWise CPQ, which fires a callback to our API. The API requests the specific line items from ConnectWise and injects them directly into the HubSpot Deal, overwriting any placeholders. The result: a single HubSpot Deal that finally represented the total contract value.

Impact

Accelerated Quote-to-Cash Cycle

We eliminated the manual double-entry of product line items between systems. That cut quote generation time from hours to minutes. Reps now spend their time selling instead of auditing SKU lists.

100% Pricing Accuracy

The custom API injection keeps the hardware pricing and MSP service fees in the HubSpot Quote as an exact match of the ConnectWise source. That erased the 5-10% error rate from manual data entry.

Unified Customer Signature Experience

All line items (ISP and MSP) now live in a single HubSpot quote template with embedded SOWs. The customer signs just one document. That lowers friction for multi-service deals.

Automated Downstream Fulfillment

Once the unified quote is signed, the "Closed-Won" trigger in HubSpot fires. It sends order data to eLation and updates the ConnectWise Opportunity at the same time. Fulfillment teams in both departments get accurate data instantly.

Technical Blueprint

Custom API Callback Architecture

We built a custom middleware listener. It monitors ConnectWise for "Quote Completed" events. When that event fires, the listener matches the ConnectWise Opportunity ID to the HubSpot Deal ID and starts the data push.

Line Item Injection Logic

The integration uses the HubSpot CRM API. It clears existing line items on a deal automatically. Then it replaces them with the detailed product set retrieved from the ConnectWise CPQ callback, keeping SKU and pricing parity intact.

Cross-Platform Trigger Synchronization

We mapped HubSpot Deal Stages to ConnectWise Opportunity Statuses. A move in HubSpot's pipeline then triggers the API calls needed to keep the MSP project and ISP order in sync, without manual intervention.

Embedded SOW Quote Templates

We customized HubSpot quote templates to pull in the ConnectWise-derived line items dynamically. They also embed standardized Statements of Work (SOWs). That gave legal and technical compliance within a single sales document.

Native CRM syncing often fails to pass detailed CPQ line items, creating gaps in the quote-to-cash cycle. Engineering a custom API callback layer bridges ConnectWise catalogs directly with HubSpot Deals. Because unified product data is injected natively into the CRM, the sales team eliminates double-entry and accelerates enterprise quoting.

FAQ

Why didn't standard HubSpot DataSync handle the ConnectWise line items?

Native sync mapped the opportunities but left the line items locked in ConnectWise, because it wasn't built for the granularity an MSP catalog requires. Reps ended up generating two quotes or copy-pasting SKUs, which drove a 5, 10% pricing error rate. We built an event-driven callback instead, so the detailed line items get pulled into the HubSpot deal rather than stranded.

How does a single HubSpot deal end up holding both ISP and MSP pricing?

A deal stage, "MSP Ready for Quote", triggers our API layer to create the matching ConnectWise opportunity. The rep builds the hardware and services in ConnectWise CPQ, which fires a callback; the API then clears any placeholder line items on the HubSpot deal and injects the ConnectWise product set, maintaining SKU and pricing parity. The result is one deal representing total contract value across both catalogs.
