Good people were losing the week to processes that no longer fitted the work. We build custom software, API integrations, and AI automation so information moves and the busywork drops away. Plain stories: before, during, after. No highlight reel. What these stories have in common A capable team Stuck in a process that no longer fitted the work. A fixable problem That had been absorbed as normal for too long. A clear path forward Once someone mapped the real workflow, not the ideal one. Logistics ## Amazon API integration for logistics firm The team was generating every shipping label by hand, spending around 40 hours a week on work a system could do. Around 40 hours a week came back to the team when shipping labels stopped being a manual job. Here is how we connected their workflow to Amazon without adding another spreadsheet layer. API Integrations Custom Software Amazon SP-API Integrations Read the case study -> Warehousing ## Real-time stock tracking across multiple warehouse locations Stock levels across three warehouse locations were tracked manually using spreadsheets. Errors were common, weekly reconciliation took hours, and nobody fully trusted the numbers. Stock errors were costing this warehouse operation time and money across every location. A custom web and mobile app with QR scanning cut those errors by 85% from the first month. Custom Software Mobile App Development Read the case study -> Recruitment ## Outgrowing Zapier: how a recruitment firm reclaimed control of its data Pinnacle Talent Group had built a network of Zapier automations connecting their ATS, CRM, and communication tools. Monthly task usage had grown to the point where costs were significant, the business logic the team actually needed could not be expressed in simple if-this-then-that rules, and maintaining the Zaps had become a part-time job. Zapier connected the tools. It could not handle the rules, the exceptions, or the cost at scale. When the monthly bill hit four figures and the logic still was not right, it was time for something better. Custom Software API Integrations Workflow Automation Read the case study -> Facilities Management ## A custom CRM that doubled conversion speed for a national cleaning company Leads were managed in a shared inbox and a spreadsheet. Follow-ups were inconsistent, scheduling was manual, and the team had no clear view of which jobs were converting or why. Leads were arriving faster than the team could handle them. A CRM built around their actual process cut manual admin by 60% and made conversions twice as fast. Custom Software Read the case study -> Health & Wellness ## From idea to live product in 14 weeks for a wellness startup The founders had a well-defined product concept and early user interest but no technical team. They needed a credible working product to launch to their first cohort and begin building commercial traction. A wellness startup had a clear product vision and no technical team. We took them from brief to a live product in 14 weeks, complete with user onboarding, subscription payments, and health tracking. Custom Software Mobile App Development Read the case study -> Property ## 30 hours a month back for a London lettings agency Every tenancy required the team to manually prepare documents, chase signatures, send compliance reminders, and update records across multiple tools. Admin was growing faster than headcount. Tenancy paperwork, client chasers, and manual compliance checks were eating the team's week. We automated the workflows and gave a London lettings agency over 30 hours a month back. Custom Software Workflow Automation Read the case study -> Logistics ## Automating order management with Amazon SP-API for a fulfilment company Amazon orders were manually copied into the company's internal order management system each day, creating delays, duplicate entries, and a daily race against incoming order volume. Amazon orders were being manually copied into an internal system every morning. We connected the two using Amazon's SP-API and gave the operations team their mornings back. API Integrations Amazon SP-API Integrations Read the case study -> Financial Services ## A secure portfolio dashboard for a financial advisory firm Advisers were pulling data from multiple sources into spreadsheets to build client reports. The process was time-consuming, prone to version errors, and not scalable as the client base grew. Portfolio data was scattered across spreadsheets and legacy tools. We built a secure, real-time dashboard that brought everything into one place and cut reporting time by more than half. Custom Software Read the case study -> Wholesale & Distribution ## Salesforce integration for a B2B wholesale distributor Salesforce held the customer relationships, but sales reps had no live access to stock levels or order history when quoting. Closing a deal required manually checking two other systems, which slowed every sales conversation. Salesforce was not talking to stock levels, orders, or customer history. Sales reps were quoting blind. We connected everything and gave the team a single view of every account. API Integrations Custom Software Read the case study -> Professional Services ## An AI-powered bot that handles internal IT support tickets A small IT support team was handling a high volume of repetitive tickets across the business. The same password resets, software access requests, and connectivity questions arrived daily, leaving little capacity for complex issues. The IT helpdesk was spending most of its time answering the same questions. We built an internal AI bot that handles common tickets automatically, routes the rest intelligently, and gave the team their capacity back. Custom Software Workflow Automation Read the case study -> SaaS / Technology ## When n8n stopped being enough for a fast-growing SaaS company Stackify Labs had built their entire operations layer on n8n. Workflows had grown organically over 18 months into a system nobody fully understood, failures were happening in silence, and the technical team was spending more time maintaining automations than building the product. n8n got them started. After 18 months of bolt-on fixes and a workflow that nobody fully understood anymore, they needed something built to last. Here is how we replaced it. Custom Software Workflow Automation Read the case study -> Construction ## Mobile and web platform for a building contractor's field operations Site teams were completing job forms on paper. The office had no real-time visibility, and important records were getting lost between sites and the admin desk. Paper forms were costing Aurora Building time on every job. Here is how we replaced the clipboard with a secure Android app and gave the office full visibility without chasing anyone. Custom Software Mobile App Development Read the case study -> Health & Fitness ## A two-sided platform connecting personal trainers with their clients Personal trainers were managing clients, building workout programmes, and tracking progress across a mix of spreadsheets, notes apps, and messaging threads. Clients had no way to access their own workouts without asking. Personal trainers were running their businesses across spreadsheets, messaging apps, and printed programmes. Fitly is the platform we built to bring all of it into one place, for trainers and clients alike. Custom Software Mobile App Development Read the case study -> E-commerce ## Beyond Make.com: custom workflow automation for a multi-brand e-commerce operation Harbour Commerce Group ran three e-commerce brands from one operations team. Their Make.com scenarios had grown to handle order routing, inventory updates, and supplier communications across all three. Under peak load, scenarios were hitting operation limits, failing inconsistently, and becoming too complex to diagnose or change without risk. Make.com handled the basics. When the order volumes grew and the scenarios became genuinely complex, the platform showed its limits. We built the automation layer the business actually needed.
