AI USE CASE
Trades Invoice and Variations Tracker
Automatically flags scope changes in client messages so tradespeople capture every billable variation.
What it is
Site managers and small contractors routinely lose 3–6% of project margin when verbal or WhatsApp scope changes never make it onto a formal variation order. This tool monitors client communication threads, detects language indicating scope changes, and prompts the site manager to raise a priced variation before the work starts. Teams using structured variation capture typically recover €2,000–€8,000 per project on small-to-mid builds. Setup requires no existing software stack — a phone and a client messaging history are enough to get started.
Data you need
WhatsApp or SMS message history with clients covering the duration of a project, ideally exported or accessible via integration.
Required systems
- none
Why it works
- Embed a simple one-tap variation-raise flow directly in the alert so the friction to act is near zero.
- Train the site manager to refer clients to messaging channels rather than phone for any scope discussions.
- Use plain-language variation order templates the client can sign digitally on the same day.
- Review flagged conversations weekly at first to tune the detection model to the team's communication style.
How this goes wrong
- Site manager ignores alerts and still agrees to extra work verbally without raising a variation order.
- Message monitoring misses scope changes discussed on phone calls or in person, giving false confidence.
- Client pushback on formal variation orders damages the relationship if not handled diplomatically.
- Integration with WhatsApp Business API breaks or requires periodic reauthorisation, creating gaps in coverage.
When NOT to do this
Do not deploy this if the business owner handles all client communication informally and has no intention of issuing written variation orders — the tool surfaces changes but cannot force billing discipline in a one-person firm that avoids paperwork.
