There is no universal answer — it depends on your stage, growth targets, and competitive environment. Early-stage SaaS companies often allocate 40-60% of revenue to sales and marketing combined. More established companies with strong product-market fit typically see this moderate to 20-35%. The more important question is not the percentage but the efficiency: what is your CAC, and how does it compare to your LTV? B2B Fusion helps clients optimize the efficiency of their GTM investment rather than simply increasing spend.
