Katalogo
My product for businesses selling through WhatsApp: a phone-friendly catalog manager, product variations, consolidated inquiries, and tools for everyday operations.
Context
An independent product for Nicaraguan businesses that need to share products, prices, and stock through a single link.
Problem
Make browsing and maintaining a catalog straightforward for buyers and business owners working from their phones.
Solution
A custom WordPress theme using PHP, ACF, and JavaScript, with an owner dashboard outside wp-admin and inquiries sent to WhatsApp. The marketing website uses Next.js and React.
Technical decisions
- Model products and variations with custom fields and expose the catalog through the REST API.
- Design quick price and stock editing, manual product ordering, and settings for phone use.
- Separate browsing from the commercial conversation: the cart prepares a message; availability and payment are confirmed outside the site.
- Provide CSV import with validation and rollback on Pro, and analytics that distinguish inquiries from sales.
- Keep each installation’s catalog, settings, and history separate, with features scoped by plan.
Outcome
A published product with demos, real catalogs linked from its website, and a public release history. The verifiable result is a browsing and management tool; WhatsApp clicks are not presented as confirmed sales.
Work delivered
Katalogo brings together my work in advanced WordPress development, interface design, product logic, and maintenance. Buyers can browse products and, depending on the plan, select variations and collect quantities in a WhatsApp message. The business keeps the direct conversation and arranges payment separately.
For owners, I built task-focused administration: edit prices and stock, order products, adjust catalog branding, and view analytics according to their plan. CSV import includes validation and rollback, because loading many products also needs a way to correct mistakes.
The marketing website at katalogonic.com is a separate application built with Next.js, React, and TypeScript. It explains plans, shows demos and client catalogs, and publishes product updates. The catalogs run on WordPress with PHP, ACF, JavaScript, and the REST API; these are two distinct parts of the same project.
The published scope does not include in-catalog payments or guaranteed sales. Features depend on the plan. Development and iteration remain part of the product rather than ending with its first release.
