HubSpot Integration Agency

The short answer

Tack Media implements HubSpot and wires it into ads, the website and the rest of the stack so marketing spend can be tied to closed revenue. Work covers portal setup, data migration, lifecycle and pipeline design, custom API integrations, and ongoing operations. Engagements start at $5,000 a month.

What we actually do with HubSpot

HubSpot is easy to buy and easy to misconfigure. Most portals we inherit have four lifecycle stages nobody agrees on and a properties list that has grown to several hundred fields.

• Portal implementation. Object model, property architecture, lifecycle stages with written definitions, deal pipelines and stage exit criteria, and permission structure.
• Data migration and dedupe. Import from spreadsheets or another CRM, with a deduplication pass and a mapping document you can audit. Batch operations against the CRM API are limited to 100 records per request, so large migrations are queued and rate-aware, not run from a laptop.
• Attribution plumbing. Click IDs captured on every form, UTM persistence across sessions, source of truth defined once, and closed-won revenue pushed back to the ad platforms.
• Workflow and lifecycle automation. Lead scoring that reflects how your sales team actually qualifies, routing rules, SLA timers and escalation.
• Custom integrations. Private apps and OAuth apps built against the CRM API where a native connector does not exist or does not do enough. HubSpot’s OAuth flow exchanges an authorisation code for access and refresh tokens, and we build the refresh handling properly rather than storing a token and hoping.
• Reporting. Dashboards a sales leader will actually open, plus the underlying data exported where deeper analysis is needed.
• Ongoing operations. Someone owning the portal week to week, which is the part most companies skip.

What it connects to

Where teams get stuck

Rate limits hit during a sync, not during a test. HubSpot publishes limits by tier. As of 26 August 2026, private apps on Free and Starter get 100 requests per 10 seconds and 250,000 calls a day, Professional gets 190 per 10 seconds and 625,000 a day, and Enterprise gets 190 per 10 seconds and 1,000,000 a day. The Search API is separately capped at five requests per second per token, which is the limit most homegrown syncs actually hit. HubSpot changes these, so we design with headroom and monitoring.

Buying the tier before scoping the requirement. As of 26 August 2026, HubSpot lists Marketing Hub Professional from $800 a month with three seats included and Enterprise from $3,600 a month with five seats, plus one-time onboarding fees of $3,000 for Professional and $7,000 for Enterprise, and marketing contact allowances of 2,000 and 10,000 respectively. The contact allowance is what catches people: an unmanaged list grows and the bill grows with it. HubSpot revises pricing regularly, so check their page before you sign.

Property sprawl. Every campaign adds a field, nothing is ever retired, and within two years reporting is unusable because three properties hold variants of the same fact. Fixing this later costs more than designing it once.

No attribution back to ad platforms. HubSpot knows which deals closed. Google and Meta do not, unless someone builds the return path. Without it, bidding algorithms optimise toward whichever leads are cheapest, which is usually the worst ones.

How it works — 1, 2, 3

1. Audit and access, week 1 to 2. Portal, properties, workflows, integrations, ad accounts and website. You get a written audit and a data model proposal before anything is changed.
2. Build and connect, week 2 to 8. Object model and pipelines first, then migration and dedupe, then automation, then the ad platform return path. A migration from another CRM typically adds two to four weeks.
3. Run and report, ongoing. Weekly operations, monthly pipeline and attribution review, quarterly cleanup of properties and workflows that have stopped earning their place.

What it costs

Tack engagements start at $5,000 a month. What moves the number: how many objects and pipelines, whether a migration is involved, how many custom integrations are required, and whether we are also running the ad accounts feeding the CRM.

HubSpot’s own subscription is separate and billed by HubSpot to you. Tiers and onboarding fees are cited above with their as-of date, and vendor pricing changes. If HubSpot is the wrong shape for your business, we will say so. Some teams are better served by Pipedrive at a fraction of the cost, and some need Salesforce.

Questions we get asked

Who owns the HubSpot portal?

You do. It is your subscription, your data and your super admin. We work as users inside it. If we stop working together, we are removed and everything stays exactly as built.

Can we take it in-house later?

Yes, and that is the intended endpoint for most clients. The data model, workflow logic, integration specs and naming conventions are documented as part of the system, not held in someone’s head.

Do you work with our existing portal?

Usually. We rarely recommend a fresh portal because history has value. We do recommend a property and workflow cleanup, and we will scope that honestly rather than pretend it is quick.

What if we already have a HubSpot partner?

Plenty of portals are well implemented and simply have no connection to the ad platforms. If that is your situation, we can build only the attribution and automation layer and leave the rest alone.

Do you build custom apps or only use native connectors?

Both. Native where it does the job, private apps and API integrations where it does not. That work lives in our automation and AI practice, and it feeds the same data our AI agents use when we build them.

The bottom line

HubSpot pays for itself when it is the place where marketing spend and closed revenue meet. That requires a clean data model and a return path to the ad platforms, and neither happens by default.
