LOGIC:Assuming an average SaaS subscription of £1,200/month per firm, the gross margin (after cloud hosting and direct 'Manchester Heritage Registry' API transaction fees) is projected at 78%. However, local operational costs are significant. Prime office rent in central Manchester (e.g., Ancoats, Spinningfields) averages £35-£45 per sq ft, meaning a modest 500 sq ft office for a small team costs £17,500-£22,500 annually. Crucially, competitive salaries for skilled software engineers (£55,000-£75,000+) and specialist sales/account managers (£40,000-£60,000+) in Manchester represent the largest overhead, making profitability highly dependent on achieving rapid customer acquisition to cover these fixed local expenses.
