Add Item or Menu that can replace the services.

Replace the term "Service" with "Item" or "Product":

Allow businesses to list their items (e.g., food menu items, retail products, etc.) in the same way they list services.
The terminology would reflect the nature of the business and improve user experience by using language that fits the context.
Customizable Item Categories:

Allow businesses to create custom categories for "Items" (e.g., Appetizers, Main Courses, Desserts for restaurants, or "Products", "Merchandise" for retail).
Provide flexibility for businesses to organize items into meaningful categories.
Add Item-specific Attributes:

Allow attributes like size, flavor, or variations (e.g., "small", "medium", "large" for food items, or "size" for clothing items) to be set for each "Item".
Enable a more dynamic reservation experience for customers.
Item Availability & Inventory Management:

Integrate inventory control for "Items", where businesses can specify the number of items available for a particular time slot.
This would be useful for food-related businesses (e.g., "Only 10 spots available for this menu item at 6 PM") or for retailers with limited stock.
Item-specific Customization Options:

Allow customers to customize items when making reservations, such as selecting toppings for a dish or personalizing a product.
Provide an interface for adding special instructions or requests (e.g., "extra cheese" or "gift wrapping").
Multiple Reservation Options per Item:

For example, a restaurant could have a single "Item" (like a "Tasting Menu") but allow reservations for different time slots or group sizes.
Retail businesses could allow customers to reserve different quantities of an item.
Item Booking Flow:

Design a streamlined booking flow that fits the item-based model, where customers select the items they wish to reserve (such as booking a table with specific menu items or reserving retail products for pickup).
