GTM Engineering Cost Calculator
Build the revenue system first. Then hire into a working system.
Selleris builds client-owned GTM systems on HubSpot. Use this calculator to choose capabilities and compare the reference build cost with an in-house GTM engineering hire. The full reference configuration is $55,000 in initial engineering - not a mandatory package or a quote. Software and optional improvements are budgeted separately.
Fixed price agreed before we start. No upfront Selleris delivery fee. No result, no invoice. You keep what we build in the diagnostic, whatever you decide.

Hiring a GTM engineer vs. building with Selleris
Compare a 12-month engineering budget. The pre-filled hiring and software figures are editable example assumptions, not market averages. Both routes need people to run sales and customer success.
Hire first
An in-house GTM engineer
Fund a person to design, build and maintain the system internally. Your scope, management and delivery risk remain in-house.
12-month scenario $164,400
$150,000 employment + $0 recruiting + $14,400 software (12 × $1,200)
Build first
Your selected Revenue Loop
Selleris builds the agreed capabilities in accounts you own. Your team runs the system. Hire into it when you are ready.
Initial Build Your selection above. Paid per verified result. $55,000
Later hire in this 12-month window $0
12-month scenario $69,400
$55,000 Build + $14,400 software (12 × $1,200) + $0 Improve + $0 later hire
The budget difference
$95,000 less in this scenario
The selected Build equals 4.4 months of the employment budget above, before tools and other costs.
No upfront Selleris delivery fee. No result, no invoice. The system stays yours.
This is a budget comparison, not a claim that a hire and a project deliver identical work. Day-to-day sales and customer-success staffing, taxes and unlisted integrations are not modelled. Provider budgets do not change automatically with module selection. An existing capability is reused only after validation. The hire-start selector is a cost assumption, not a promised delivery date.
Implementation Cost
What determines HubSpot implementation cost?
Your budget depends on what already works, data quality, integrations, process complexity, migration scope and team handover. The diagnostic turns those requirements into one fixed Build price. Software, data and future Improve work stay separate.
-
What already works
Usable CRM foundations, segmentation and workflows are retained after validation instead of rebuilt.
Existing equivalents can reduce the new Build scope.
-
Data quality
Duplicates, missing fields and inconsistent records change the preparation and validation work needed before automation is reliable.
Cleaner data means less remediation before launch.
-
Integrations
The systems to connect, their APIs and the direction of data flow determine integration effort and test coverage.
Provider fees stay separate from Selleris engineering.
-
Process complexity
The selected capabilities, routing rules, permissions and approvals determine how much must be built, tested and documented.
The diagnostic turns this into one fixed Build price.
-
Migration scope
The records, activities, attachments and historical relationships you need to preserve determine the migration work required.
Move what the new system needs, not every legacy record.
-
Enablement and handover
Documentation, training and acceptance checks are planned around your users and workflows, so your team can take over the system.
Included in the agreed Build scope, not a surprise add-on.

FAQs
GTM system pricing and hiring questions
Understand the reference price, what you can reuse and what each payment depends on before choosing your next step.
Is $55,000 a fixed package price?
No. $55,000 is the illustrative initial engineering cost of the full Selleris Revenue Loop reference configuration: 12 capabilities at $52,500 plus a $2,500 System of record foundation, in USD as of September 2026. It is not a required package or a quote. The free diagnostic determines your recommended initial Build and one fixed price before you commit. See the Revenue Loop scope and payment terms.
Can I start with fewer capabilities or reuse my existing setup?
Yes. Selleris scopes the capabilities your next stage of growth needs and validates existing equivalents before rebuilding anything. Some capabilities need specific inputs, but that does not make every earlier sprint a required purchase. The calculator flags missing prerequisites and lets you add the relevant build or identify an existing equivalent. Your selected subtotal remains a reference estimate until the diagnostic confirms the scope.
Are HubSpot subscriptions and ongoing improvements included?
The initial Build estimate covers Selleris engineering, not HubSpot subscriptions, third-party tools, credits or cloud usage. Provider costs are disclosed separately and paid directly to providers with zero Selleris markup. Further support, calibration and development are separately agreed Improve work, not an automatic monthly retainer. The calculator lets you budget these expenses separately; entering $0 for Improve means no allowance has been added, not unlimited free support.
When should I hire a GTM engineer instead of working with Selleris?
An in-house GTM engineer can be a good fit when you have a continuing engineering workload and someone to manage the function. A capable engineer can also build from scratch. Selleris is an alternative for a defined implementation with agreed scope, acceptance criteria and documentation. You can also build with Selleris and hire later. The calculator compares budgets; it does not claim that a project and a full-time employee deliver identical work.
How long does implementation take?
Selleris sets delivery dates and verification periods for your selected Build after the diagnostic. Timing depends on the capabilities selected, the state of your data, integrations and the readiness of agreed inputs and access. The 12-month calculator window is a budget comparison, not an implementation schedule, and the selected hiring month is not a promised completion date. The free diagnostic takes ten calendar days after the agreed data and access are ready.
What does my team need to do during the build?
Selleris performs the engineering. Your team provides the agreed access and business context, makes commercial decisions and reviews the results. Some sprints need only approvals; others need joint work on qualification rules, stages, pricing or account triggers. Each sprint closes with an acceptance review. The exact inputs and client responsibilities are agreed before work starts. Your team continues to run sales conversations, customer relationships and daily revenue operations.
What result determines whether a sprint is paid?
A sprint is paid when its agreed acceptance criteria have been met and verified. The acceptance number measures the system we built, using the method and data agreed before the sprint. The effect number measures the later business result, such as meetings, pipeline or retention, which also depends on your market and team. No result, no invoice refers to the agreed delivery result - not an unconditional revenue guarantee. A missed delivery criterion is reworked at Selleris’s cost.
