I commit to preparing all print-ready interior files, managing the KDP and IngramSpark listings, optimising product pages for conversion, tracking monthly sales against these targets, and reporting variances with corrective actions. If Month 3 sales fall below 60% of target, I will recommend and implement a revised acquisition strategy including targeted social media content and engineering community outreach. These are my targets — conservative, achievable, and accountable.
Zero sales tax on all channels (physical + digital). No VAT collection burden means simpler checkout and higher conversion. Under the Conservative scenario, 4ECL operates at a net loss in Year 1 — no profits tax payable. The operating loss carries forward indefinitely to offset future profits.
