we run an e-commerce site selling custom home textiles and curtains. tbh our average monthly revenue is around 250,000 TL. about 80 percent of our site visitors come from mobile phones. a software agency we spoke with last week said our mobile cart abandonment rates are high and that we urgently need a custom mobile app (iOS and Android). they put an offer on the table: 350,000 TL for setup, followed by a mothly maintenance and server fee of 15,000 TL.
our site is already responsive; it fits the screen properly on mobile and the menus work fine. but the folks at the agency claim websites are outdated and that an app is a must to retain customers but tying up such a huge budget in an app is a serious risk for our business. is a mobile app really essential for every e-commerce business or does it make more senes to stick with mobile web?
