Bespoke Software to Transform Your Business

At JustApplications, we create custom web and mobile platforms that automate complex workflows and boost productivity across ecommerce, retail, energy and field-service industries. Our expert team works with the latest technologies (Laravel, Ruby on Rails, Flutter, React, etc.) to digitize processes that were once manual. We’ve even developed our own in-house tools — like Ad-Lister, JustShipIT and Nventree — that serve thousands of online sellers . The result? Complex tasks become simple, your team saves time, and your bottom line grows.

We solve your toughest problems with tailored software. Whether you need to modernize a legacy system or launch a new app, our solutions drive efficiency and revenue. By introducing automation (for example, bulk listing updates or automatic stock syncing), our clients routinely see faster operations and higher sales . Below are some examples of how we’ve delivered digital transformation for
businesses like yours

Multi-channel Order Management Software

Nventree is our multi-channel inventory system, it automatically syncs stock levels, pricing, and product details across Amazon, eBay, Shopify, B&Q, TikTok and other channels from a single interface . Nventree even integrates courier shipping so you can print labels and dispatch orders in one click .Your team can download all marketplace orders in once and provide fulfilment in bulk. They simply print pick/pack lists and carrier labels, apply tracking codes and mark orders dispatched — all from one easy interface . These tools eliminate manual channel-hopping and reduce errors.

Manage multi-channel listings: Create and update products on eBay, Amazon, Shopify, Magento etc. from one portal.
Centralize orders & fulfillment: Import orders from every sales channel into one workflow. Generate pick/pack lists, print courier labels, and send tracking info automatically.
Automate inventory & pricing: Keep stock and prices in sync across all stores. Nventree’s dashboard gives you a real-time view of inventory and sales on all connected platforms.
Boost sales & insights: Cross-promote your own products (bundles, top-seller banners, related items) and analyse competitor data. Ad-Lister can even tap into competitors’ sales histories to suggest your next best seller.

These solutions help ecommerce and retail businesses cut manual work and grow sales simultaneously.

Energy & Utilities Management

For energy companies and consultants, we build portals that simplify billing and compliance. For example, we developed a secure customer portal for Ginger Energy (a utility consultancy) where users can: access multiple sites, view and download invoices for electricity or heat, and see consumption charts . Customers can also submit meter readings (for gas, electricity, district heating, etc.), set up direct-debit mandates, and submit change-of-occupancy forms online . This replaces paper processes and phone calls with a few clicks – saving staff hours and improving customer satisfaction.

Multi-site billing: Users log into one system to manage utility bills across all their properties
Invoice & Statement access: Instantly download any invoice or view monthly statements for
electricity, gas or heat .
Meter reads & payments: Submit meter readings and set up payments or direct debits online,
eliminating paperwork .
Usage tracking: Generate charts and reports to understand consumption and identify savings.

By digitizing these processes, energy firms can reduce costly errors and focus on strategic procurement, while end customers get 24/7 self-service.

It also includes social features to connect clients with vetted tattoo artists. While InkJin serves the tattoo industry, the same cross-platform mobile expertise can apply to any niche market. Whether it’s a beauty and wellness portal, a custom ordering app, or a unique customer engagement tool, we design mobile solutions with an intuitive UX that delights users.

Cross-platform mobile: Our mobile apps run on iOS and Android, often built with Flutter for a consistent experience .
Augmented experiences: Incorporate AR, image recognition or location services when it makes sense – as we did for InkJin’s virtual tattoo previews .
Custom integrations: Connect your app to back-end systems (like CRM, ERP or payment gateways) just as InkJin connects to a content database.
Scalable cloud back-end: We use robust platforms (Drupal, Laravel, Ruby on Rails, Python) to ensure your app can grow.

Our approach is always user-centric: we storyboard, prototype and get feedback early to ensure the final product is clear and engaging.
