The challenge
Engineers were spending up to 30 minutes on every report, typing up observations, uploading photos, and formatting emails after each job. Reports were only filed once engineers got back to a laptop, sometimes the next day. Quality and detail varied between engineers, and photos were scattered across phones and email threads.
The approach
Reporting built into WhatsApp, the tool they already use every day.
Rather than introducing a new app, Tradestack built directly into WhatsApp.
Image analysis
AI reads every photo in detail.
Environment, meter readings, damage, manufacturer details. Deep visual context extracted automatically from every image sent.
Voice transcription
One minute of voice, pages of context.
Fast, accurate transcription that captures the detail engineers naturally include when they talk through what they found on site.
Conversational AI
Intelligent back-and-forth.
The operator manages the conversation with smart turn-taking, asking the right follow-ups and confirming details before compiling the report.
Deep context layer
Cross-project memory.
The operator builds context over time across jobs, clients, and sites. Previous work and history informs every current conversation.
Starting annual service on Vaillant ecoTEC at De Vere, Kensington. Unit 3, plant room B.
Logged. Is this the same unit from the January callout?
Yeah same one. Running fine now though.
Flue readings on the analyser. All within spec.
Got the readings. Anything else to note before I compile?
Filter cleaned, condensate trap cleared. All good for another year.
Report compiled and filed to Drive (De Vere > Annual Service). Office notified.
Branded PDF reports
Company-branded, client-ready.
Every report generated in MEC's own template. Professional formatting, embedded photos, and consistent quality across every single report.
Integrated distribution
Simpro, Drive, email. All connected.
Reports are filed to Google Drive, synced with Simpro, and emailed to the right people automatically. No manual steps or duplicate entry needed.
Intelligent filing
Organised for retrieval.
Reports filed by client, project, and date. Structured data that feeds into compliance records, job costing, and future reference lookups.
Team access
Every engineer sees every report.
Shared folders give the whole team access to past reports across sites and projects. Engineers can reference previous work before arriving on site.
