Honest Answer

Yes. But you do not need a comprehensive VI - you need an MVP version that is good enough.

MVP VI Contents

LOGO (with specs). Business card template. PPT template (cover, content, closing slides). Social media avatar plus cover image. Email signature. Cost: freelancer 3,000-8,000 RMB. Agency 10,000-20,000 RMB.

When to Upgrade

Team >10 people. Annual revenue >5M. Expanding beyond local market. Preparing for funding. Current VI feels too small for current scale.

Two e-commerce teams started same time in 益阳. Team A skipped VI (spent on ads instead). Team B spent 5,000 on LOGO plus card plus PPT. Two years later: Team A monthly revenue ~150K, Team B ~280K. Cannot attribute solely to VI, but Team B founder noted: in one major client meeting, buyer explicitly said your materials look more professional. 5,000 investment = professional impression in countless business occasions. Less than 7 RMB per day. Worth it?
