Hi. I can help you to create a CSV Export Interface App in Shopify. I would develop a user app on Shopify which gathers all transactional data per month into the Dutypay CSV Format. The app will be published in the Shopify app market. I have 15+ years of experience in Shopify & Wordpress and I can build a user-friendly app in a more professional way. I am a " Certified Shopify Partner" and I would handly your project personally.
Actually, I'm running a company for over 12 years and we have a team of Specialists who have vast experience in Web, Software, Apps, Architecture, etc. We don't compromise on quality. We have one main goal which is "Customer Satisfaction".
I am looking forward to starting this project as soon as possible with you.
Regards
