Questions, answered
Frequently asked about Big Business Agency
The short version is on the surface. Open any question to go deeper.
Big Business Agency is a specialist B2B sales consulting, lead generation and systems-integration firm that helps companies digitise and unify operations from sale to service. The agency designs GTM strategies, omnichannel LinkedIn and Google Ads programmes, and SDR enablement while implementing HubSpot-centric CRM, CPQ, customer portals and quote-to-cash automation, particularly for complex B2B organisations in sectors like TIC, manufacturing, professional services and software.
Big Business Agency does not publish standard pricing or packaged SDR seat rates; engagements are scoped and priced custom based on project complexity, services involved and technology footprint. Third-party directories indicate typical minimum project sizes in the USD $5,000-$10,000+ range and an average hourly rate in the premium band, but official pricing is only available by contacting the firm directly.
Key capabilities include ICP and target-account mapping, omnichannel lead-generation campaigns across LinkedIn, Google Ads and email, Ad Intent Data for real-time attribution and lead capture, lead scoring and automated nurturing, sales enablement and Big Deal coaching, HubSpot CRM implementation and optimisation, CPQ and quote-to-cash automation, B2B eCommerce portals, customer-service workflow automation and analytics dashboards that tie marketing activity to revenue.
In the SDR and B2B lead-generation space, buyers often compare Big Business Agency with outsourced SDR and appointment-setting providers such as CIENCE, Belkins, Martal Group and Sopro, as well as with other HubSpot-focused consultancies and RevOps agencies. The key difference is that Big Business Agency emphasises senior sales consulting, HubSpot and ERP integration and omnichannel campaigns over providing large pools of outsourced SDRs.
Big Business Agency can be a strong fit for ambitious small and mid-sized B2B companies that sell higher-value offerings and are ready to invest in HubSpot, process design and targeted lead generation. However, very small or budget-constrained businesses looking for low-cost, self-serve tools, or B2C-only brands with simple funnels, may find the consulting-heavy engagement model and typical project sizes more than they need.
