HubSpot consultants help companies set up, migrate to, customize, and get more out of HubSpot's CRM and its Marketing, Sales, Service, Operations, and CMS hubs. Most work solo or in small agencies and bill for portal audits, implementations, data migrations, workflow and automation builds, reporting, training, and ongoing admin support. Invoices usually tie to a defined project, a block of hours, or a monthly retainer.

Most HubSpot consultants mix three models. Hourly billing is common for support, troubleshooting, and work with unclear scope. Fixed-fee projects are standard for implementations, migrations, and audits, often split into milestones such as discovery, build, and training. Monthly retainers cover ongoing admin, reporting, list and workflow maintenance, and a set number of hours, with unused hours either expiring or rolling over for a short time. Training is often billed per session or as a half-day or full-day workshop. Pass-through costs such as the client's HubSpot subscription, onboarding fees paid to HubSpot, third-party connectors, or contractor help should be listed separately from your labor. Clients usually buy their own HubSpot licenses directly, so most consultants do not resell software.

Notes: Payment due within 15 days of invoice date. Milestone 2 of 3 per the signed statement of work dated March 4. HubSpot subscription fees are billed to the client directly by HubSpot and are not included here. Late balances accrue 1.5% per month.
Ties the charge to an agreed scope and deliverable so the client can match it to the contract.
Many clients have multiple portals or sandboxes, and this shows exactly where the work was done.
Listing workflows built, records migrated, and properties created proves what was delivered and avoids disputes over scope.
Support and troubleshooting are easy to question without a dated breakdown of what was done.
Shows change requests as distinct from the fixed fee, so extra charges are not a surprise.
Connector subscriptions, contractor fees, or paid onboarding services should be itemized apart from your labor.
Clarifies what the monthly fee covers and whether any hours expired or rolled over.
Fixed-fee projects commonly require a 30-50% deposit at kickoff, with the rest tied to milestones such as end of build and go-live. Retainers are usually billed in advance on the first of the month. Net 15 is typical for project invoices, and net 30 is common when working with larger companies that have an accounts payable process. Many consultants add a late fee of 1-1.5% per month, stated in the contract before work starts. Payment is usually by ACH, card, or check, and some consultants pause admin access or new work on accounts that are more than 30 days past due.
Billing at discovery, build, and go-live keeps cash flowing on long implementations and gives the client clear checkpoints. It also protects you if the client delays feedback and the project drags on.
HubSpot projects grow easily: another pipeline, another integration, one more import. Define what is included and bill additions at your hourly rate with written approval.
Have clients buy and hold their own licenses. Keep your invoice limited to your services and any pass-through costs you actually paid, so you are not on the hook for software renewals.
State whether unused hours expire at month end or roll over for a set period. Without that, clients may expect banked hours indefinitely.
Document your access level and when it ends. Billing for work in a portal is easier to defend when the client has acknowledged what you were authorized to change.
Flat fees work well when the scope is clear, such as a defined number of pipelines, properties, and workflows. Use hourly for audits that lead to unknown work, troubleshooting, and projects where the client keeps changing requirements. Many consultants quote a flat fee with hourly rates for anything outside the scope.
Only if you are an authorized partner with a reseller arrangement and your agreement with HubSpot allows it. Most solo consultants have clients buy directly from HubSpot, which keeps the license in the client's name and keeps your invoice to labor only.
Include discovery in a fixed fee as its own line, or bill it hourly if the scope is not yet defined. For ongoing projects, state in your SOW how many status meetings are included, and bill extra calls at your hourly rate.
Include a clause that work pauses if feedback or access is delayed beyond a set period, such as 14 days, and that remaining milestones may still be invoiced on schedule or the project re-quoted to resume. Bill completed milestones promptly rather than waiting for the project to finish.
It depends on the state. Some states tax software-related services or digital services, while many do not tax professional consulting. Check your state's rules or ask an accountant, and show any tax you collect as its own line on the invoice.
