HubSpot Integration Providers (2026): Options for SaaS Vendors and for HubSpot Customers, With Prices

HubSpot integration providers serve two different buyers. A SaaS company shipping a HubSpot integration to its own customers chooses between building on HubSpot's developer platform, a unified API (Merge), an embedded iPaaS (Paragon, Prismatic, Cyclr, Workato, Tray), code-first integration infrastructure (Nango, Ampersand) or a done-for-you native app build. A company connecting its own HubSpot uses HubSpot's connectors, the 2,437-app Marketplace, iPaaS tools, or a Solutions Partner such as SyncMatters or IntegrateIQ.

Which kind of HubSpot integration provider do you need?

The kind of HubSpot integration provider you need depends on whose HubSpot account the integration connects to. The two buyers ask different questions and end up with different vendors, so most provider lists that mix them are hard to use. The table shows the split this article follows.

If you are a SaaS company adding a HubSpot integration to your product

A SaaS company that wants a HubSpot integration without building it all in-house has five options: build on HubSpot's developer platform, use a unified API such as Merge, use an embedded iPaaS such as Paragon, Prismatic or Cyclr, use code-first infrastructure such as Nango or Ampersand, or pay an engineering firm to build a native HubSpot app that you own. The right choice depends on how many integrations you need in the next year, whether you want a HubSpot Marketplace listing, and whether the vendor's billing unit grows faster than your revenue per customer. The HubSpot integration platform architecture patterns article covers the system design behind each option.

HubSpot integration for your SaaS: build in-house vs Merge vs Paragon vs a deep integration platform?

The matrix compares the five options on billing unit, published price, Marketplace listing and code ownership. Prices are the published starting points on each vendor's pricing page, checked September 17, 2026. "Quote only" means the vendor publishes no figure and prices by custom quote.

Three details in the matrix change real decisions:

• Merge is a unified API, not an embedded iPaaS. Merge describes its product as shipping customer-facing integrations "through one API" with normalized Common Models. For HubSpot those models are Account, Association, AssociationType, Contact, CustomObject, CustomObjectClass, Engagement, EngagementType, Lead, Note, Opportunity, Stage, Task and User. Merge lists custom fields and custom sync frequencies under Professional, not Launch.
• Sync timing differs by design. Merge's HubSpot sync frequency depends on plan and Common Model, from daily to every 5 minutes, with Force Resync or Automatic Webhooks for faster updates (Merge HubSpot page). Paragon's HubSpot integration exposes actions (Create Record, Update Record, Get Records, Get Record by ID, Search Records, Delete Record by ID, Get Contacts by List ID) and webhook triggers (New Record, Record Updated, Record Deleted, Record Deleted for Privacy), with custom objects handled through Custom Object Mapping.
• Only a HubSpot app can put UI inside HubSpot. A unified API or embedded iPaaS moves records. If your product needs a surface inside the HubSpot record page, you need your own app with app cards built with UI extensions.
• Nango and Ampersand price differently from each other. Nango's free tier is capped at 10 connections, 10 compute hours and 10 GB a month; pay-as-you-go draws $0.29 per connection, $0.72 per compute hour and $0.50 per GB from the included credits, and Enterprise is custom with self-hosting. Nango's code is public on GitHub. Ampersand's Accelerate plan is custom-priced and covers up to 200 customers.

Paragon's pricing page lists Platform and Enterprise tiers, both sold by custom quote, with unlimited integrations on every plan. Prismatic sells Scale, Enterprise and Custom tiers on volume per-instance pricing and says it never bills on API calls or executions. Workato and Tray publish no prices.

The done-for-you row is a service, not a platform: the output is a native HubSpot app, so the listing rules below apply to it exactly as they apply to an in-house build. Disclosure: Appnigma, the author's company, sells this kind of build, which is why this row describes the category and does not rank vendors in it.

What HubSpot requires before you can list an app on the Marketplace

HubSpot's App Marketplace listing requirements apply no matter which option above builds the app. Before a listing is accepted, the app must meet these conditions:

• It uses OAuth as its sole authorization method.
• It authorizes with the single public app ID tied to the listing.
• It has at least three active installs from unique, unaffiliated production accounts. HubSpot counts an install as active when it shows successful app activity in the past 30 days, measured by OAuth-authenticated API requests or signed webhook requests.
• It runs on a supported developer platform version.
• It does not use classic CRM cards, which have been unsupported since June 16, 2025. Current apps use app cards built with UI extensions.
• AI connector apps must require user-level permissions and be built with HubSpot's MCP Server.

The Certified App badge is a separate, higher bar. HubSpot's certification requirements ask for at least 60 active, unique, unaffiliated installs (test accounts excluded) and at least six months listed. Certification lasts for a rolling two years and is removed if installs fall below 60 over a trailing six months. The HubSpot app certification requirements guide walks through the full checklist.

Rate limits also differ by how the app is distributed, per HubSpot's usage guidelines:

The daily limit is shared by every app in the account. The API limit increase add-on lifts privately distributed apps to 250 requests per 10 seconds and adds 1,000,000 requests a day on top of the account's base daily limit for each increase, up to two increases. It does not raise Marketplace OAuth apps. For a bidirectional sync, the 110-per-10-seconds ceiling per installing account is the number to design around.

HubSpot's usage guidelines still name 2025.2 and 2026.03 as the latest platform versions; expect 2026.09 to be treated the same way.

Who absorbs HubSpot developer platform changes?

HubSpot ships a new developer platform version every March and September, and each version becomes unsupported 18 months after release, according to HubSpot's versioning page. Version 2025.2 shipped September 2, 2025, 2026.03 on March 30, 2026, and 2026.09 became available September 8, 2026. Version 2023.2 was sunset October 1, 2025 and 2025.1 on August 1, 2026. Since March 30, 2026, HubSpot APIs use date-based versions in the path (/YYYY-MM/), while legacy v1 to v4 URLs are still supported.

That cadence means a HubSpot integration needs an upgrade plan at least every 18 months. With an in-house build or code-first infrastructure, your engineers own the upgrade. With a unified API or embedded iPaaS, the vendor updates its connector and you update whatever you built on top of it. With a done-for-you build, the contract decides, so ask before signing.

How to plan for more integrations later

A SaaS company that expects to add many more integrations should weigh the per-unit fee against the cost of repeated builds. A native build covers one platform per build, so each new CRM or category is another project. A unified API or embedded iPaaS spreads one integration effort across many apps, and its bill grows with the metered unit instead.

Merge's published Launch pricing shows how that unit scales. At 10 Linked Accounts the plan costs $650 a month. At 50 Linked Accounts it costs $650 plus 40 times $65, or $3,250 a month, before any move to a contract plan. If your roadmap is HubSpot plus Salesforce, a native build per CRM stays a short list. If it is 20 apps, a per-unit platform is usually the only practical way to cover them.

Which embedded integration platform can sync a SaaS product both ways with HubSpot and NetSuite?

A SaaS product that must sync with each customer's HubSpot and each customer's NetSuite needs a vendor that covers both CRM and ERP connectors. Merge, Paragon, Prismatic, Nango and Ampersand all publish a NetSuite integration page alongside their HubSpot coverage, so the matrix above still applies. Check each vendor's NetSuite page for the records and sync direction you need before you choose.

A company syncing its own HubSpot and its own NetSuite has a simpler route. HubSpot's own NetSuite integration is available on all HubSpot products and plans, and a Data Hub subscription is needed only to create custom field mappings. It maps HubSpot contacts to NetSuite contacts or individuals, companies to companies, deals to opportunities, orders to sales orders, invoices to invoices, products to NetSuite item types, tickets to support cases, and activities to calls, events and tasks. You can configure a one-way or two-way sync.

On the NetSuite side, a NetSuite administrator must enable SOAP web services, REST web services, token-based authentication, server SuiteScript and SuiteAnalytics Workbook, and install the HubSpot Sync bundle and HubSpot Sync role. For companies connecting their own systems, Celigo lists a HubSpot to NetSuite integration that syncs deals, companies, contacts and opportunity data, and SyncMatters focuses on connecting HubSpot to ERPs including NetSuite.

If you are connecting your own HubSpot to your other systems

A company connecting its own HubSpot should check options in this order: a HubSpot-built connector, then an app from the HubSpot App Marketplace (2,437 apps listed on September 17, 2026, per the all-apps page), then an iPaaS such as Zapier, Make, Celigo or Workato, then a custom build by a HubSpot Solutions Partner that holds the Custom Integration accreditation. Marketplace apps are free to install and the app's vendor bills separately for its own product. The HubSpot Marketplace complete guide explains how listings and installs work.

HubSpot iPaaS vs native integration: which fits?

A HubSpot-built connector is the least work when it exists, but some connectors need a paid HubSpot tier. HubSpot builds and maintains the common ones itself, including its Gmail, Slack and Zoom integrations, so check the Marketplace for your system before you price a build. The table compares the options a HubSpot customer has.

HubSpot's Salesforce integration needs a Salesforce edition with API access, or Salesforce Professional Edition, and it supports Salesforce Government Cloud. The Salesforce user who connects it must be a system administrator with the API Enabled and View Setup and Configuration permissions. The HubSpot Salesforce integration guide covers setup and field mapping.

Who are the HubSpot integration service providers?

HubSpot integration service providers for companies connecting their own HubSpot include SyncMatters, IntegrateIQ, SyncSmart, Struto, New Breed, SmartBug Media and Huble on the agency side, and Celigo, Commercient, Zapier and Make on the platform side. The table lists how each describes itself and what to check before you shortlist. Partner tiers change, so confirm current status in HubSpot's Solutions Directory.

Two HubSpot credentials let you check an agency's claims instead of trusting its own page. The Solutions Partner Program has tiers, and HubSpot's Custom Integration accreditation is "for partners who custom-build integration solutions for customers using HubSpot developer tools". A partner must be at the platinum, diamond or elite tier to apply for it and to keep it. For buyers outside the US, the Solutions Directory also has location pages (for example, its United States page), which is a quicker way to find an accredited partner in a given market than a global listicle. The HubSpot partners directory guide explains how the directory ranks and filters partners.

App vendors sit in a different program. HubSpot's Technology Partner Program, which HubSpot describes as the evolution of the App Partner Program, has more than 1,600 companies, and joining requires an app with at least 3 active customer installs. The HubSpot partner programs explained article compares the programs.

How much does a HubSpot integration cost?

What a HubSpot integration costs depends on the provider type, and only some providers publish prices. HubSpot-built connectors cost nothing extra beyond the HubSpot subscription they require, which for Salesforce means a Professional or Enterprise tier. Marketplace apps are free to install, with the app vendor billing for its own product. HubSpot Data Hub Professional starts at $800 per month and Enterprise at $2,000 per month on HubSpot's product page. For SaaS vendors, the published figures are the ones in the matrix above: Merge from $650 per month for 10 Linked Accounts, Nango from $50 per month, Ampersand Catalyst from $999 per month and Cyclr from $1,595 per month, while Paragon, Prismatic, Workato and Tray quote.

Agency builds and done-for-you builds are quoted per project. Ask every provider for the same three things: the billing unit, the price at your expected customer count in year two, and who pays for upgrades when a HubSpot platform version is sunset.

Checklist before you sign with a HubSpot integration provider

Use this checklist before signing with any HubSpot integration provider. Each item maps to a fact in this article.

1. Confirm which buyer you are: a SaaS vendor shipping an integration, or a company connecting its own HubSpot.
2. Check HubSpot-built connectors and the Marketplace before paying for anything, and confirm the HubSpot tier each connector requires.
3. Get the billing unit (Linked Account, Connected User, instance, connection, production customer or engagement) and price it at your year-two volume.
4. If you want a Marketplace listing, confirm the app will use OAuth only, a single public app ID, and your own HubSpot app.
5. Ask who upgrades the integration when a HubSpot developer platform version is sunset.
6. Get code and IP ownership in writing.
7. For agencies, check the tier and Custom Integration accreditation in the Solutions Directory.
8. Model total cost over 24 months, not just year one.
9. Read at least one named customer reference for the vendor you pick.

Frequently Asked Questions

Who are the main HubSpot integration providers?

For SaaS vendors, the main providers are Merge (unified API), Paragon, Prismatic, Cyclr, Workato and Tray (embedded iPaaS), Nango and Ampersand (code-first infrastructure), plus engineering firms that build native HubSpot apps. For companies connecting their own HubSpot, they are HubSpot's own connectors, Marketplace app vendors, iPaaS tools such as Celigo, Zapier and Make, and agencies such as SyncMatters, IntegrateIQ, SyncSmart and Struto.

Is Merge an embedded iPaaS or a unified API?

Merge is a unified API. It exposes HubSpot data through normalized Common Models such as Contact, Account and Opportunity, while embedded iPaaS vendors such as Paragon and Prismatic let you configure integration workflows per connector.

Can an app built on an embedded iPaaS be listed on the HubSpot Marketplace?

Yes, if it uses your own HubSpot app. Paragon's HubSpot docs describe the publishing step, a Redirect Page that calls paragon.completeInstall, and the app still has to meet HubSpot's rules: OAuth only, a single public app ID, and at least three active unaffiliated installs.

Is HubSpot's Salesforce integration free?

HubSpot's Salesforce integration has no separate fee, but it requires a Professional or Enterprise subscription to Marketing, Sales, Service, Data or Content Hub, or Smart CRM. On the Salesforce side it needs an edition with API access or Professional Edition.

Does HubSpot have a native NetSuite integration?

Yes. HubSpot's NetSuite integration is available on all HubSpot plans, supports one-way or two-way sync, and needs a Data Hub subscription only for custom field mappings.

Are integrations like HubSpot included or billed separately by software vendors?

It depends on the vendor. HubSpot Marketplace apps are free to install, and each app's vendor bills for its own product under its own plans, so check that vendor's pricing page to see whether its HubSpot integration is included in your tier.

Should a service business use a native HubSpot integration or Zapier?

Use a HubSpot-built connector or a Marketplace app when one covers the system you need, because the vendor maintains it. Use Zapier or Make for simple flows between systems that have no connector, and accept that you maintain those flows yourself.

What is the difference between a HubSpot Solutions Partner, a Technology Partner and a HubSpot integration partner?

"HubSpot integration partner" is not a HubSpot program name; it usually means one of two things. A Solutions Partner is a services firm that implements HubSpot for customers, and some hold the Custom Integration accreditation. A Technology Partner is a software company in HubSpot's Technology Partner Program, which requires an app with at least 3 active customer installs.
