FAQ
FAQ: Website Development, AI Solutions & Customer Acquisition
Answers to frequently asked questions about website development, AI solutions, customer acquisition, and business automation.
Can I hire you for website development from outside Kumamoto, Kyushu, or Japan?
+
Absolutely! Byosoku Lab is a Kumamoto-based freelance AI engineer serving clients across Kumamoto, Kyushu (Fukuoka, Saga, Nagasaki, Oita, Miyazaki, Kagoshima), nationwide, and worldwide. In-person meetings are available in Kumamoto Prefecture. For clients elsewhere in Kyushu or beyond, we conduct all meetings online via Zoom or Google Meet, so location is never a barrier.
How much does website development cost?
+
As a freelancer with zero middleman markup, Byosoku Lab offers websites from ¥50,000 — keeping costs efficient. All plans include SEO optimization and full mobile responsiveness.
What's the advantage of hiring a freelancer over an agency?
+
Zero middleman markup means lower costs with equal or better quality. At Byosoku Lab, the person you talk to is the person who builds it — no game of telephone between account managers and developers. This means faster communication, quicker turnarounds, and direct access to technical expertise. We're trusted by small businesses and startups alike.
What is an AI chatbot and what can it do?
+
An AI chatbot is an automated response system powered by large language models (LLMs) like ChatGPT and Claude. It can be deployed on your website or LINE account to handle FAQ responses, appointment booking, product inquiries, and quote requests 24/7. Clients have reduced their support workload by up to 90% after deployment.
How long does website development take?
+
Landing pages can be delivered in as little as 1 week, and corporate sites typically take 2–4 weeks. Our AI-powered development workflow enables efficient timelines. Rush projects are welcome — just ask.
Is SEO included?
+
Yes, comprehensive SEO is included in every website project. This covers HTML structure optimization, meta data, image optimization, automatic sitemap generation, structured data (JSON-LD) implementation, and Core Web Vitals optimization — a complete technical SEO package.
How much does AI chatbot development cost?
+
AI chatbots are available from ¥29,800/month (free initial setup). Pricing varies based on project scope and features (LINE integration, CRM integration, multilingual support, etc.). Book a free consultation and we'll provide a tailored proposal and quote.
Can you redesign an existing website?
+
Absolutely. We handle WordPress migrations to modern frameworks (Next.js, Astro, etc.), design overhauls, CMS integration, and performance optimization. We also offer free website analysis and improvement proposals.
Where should I start with business automation?
+
Start by listing the tasks you repeat every day — data entry, email replies, report generation, social media posting. Almost any routine task can be automated. In our free consultation, we'll analyze your workflow and prioritize automation opportunities by ROI. We've helped businesses save 30+ hours per month.
Do you offer post-delivery support?
+
Yes, every project includes 1 month of free support after delivery. Minor bug fixes and text changes are covered at no cost. For ongoing maintenance and operation needs, we also offer monthly maintenance plans.
