Frequently Asked Questions
How much does an eCommerce website cost?
eCommerce sites with Aventus typically range from £799 to £2,999 depending on size, custom illustration and integrations. Every project is fixed-price, no surprise invoices.
Can you integrate with my payment and marketing tools?
Yes. Stripe, PayPal, HubSpot, Mailchimp, Salesforce, Pipedrive and most eCommerce automation tools connect cleanly. Orders and customer data land where your team already works, with no double entry.
Will my new site rank on Google?
Every site ships with on-page SEO, schema markup and Google Business Profile optimisation. We also build collection structures and competitive keyword pages to defend your category and outrank smaller players.
How long does it take to launch?
Most eCommerce sites go live in 4–6 weeks from kickoff. We handle stakeholder reviews, copy, migration and 301 redirects so traffic and rankings don’t drop.
