I'm Sarosha from Aiva Overlays! Our app can help you set up campaigns on specific product pages where you'd like your visitors to call and inquire about pricing.
These campaigns can appear in a variety of ways, but to accomplish your purpose they'd work best if it either slides-in/pops-up or appears as a bar. All you'd have to do is find a "Tap-to-Call" template you like, customize it to your branding and publish on specific product pages. You can learn more here (see Call a Phone Number section).
TIP: You could also schedule your campaign to receive calls during business hours and email inquiries when you're closed.
Let me know if you have any questions!!
Call For Price App by SetuBridge offers exactly your desired functionality to display the “Call For Price” button instead of price. Interested visitors can also send queries through inbuilt & customizable “Ask For Price Form”.
The app looks like the perfect solution for your required concern.
