01 / THE BLUEPRINT
The problem to investigate
Small builders may order cement, tiles or steel only to discover a mismatch between invoice, delivery and what actually reached site. Confusion can delay a project and create mistrust between drivers, contractors and suppliers.
02 / THE BLUEPRINT
A possible solution
Offer a neutral delivery-confirmation workflow: compare purchase order and dispatch record, count or weigh according to a mutually agreed method, record visible condition and obtain approved acknowledgements. It is not structural-material certification.
03 / THE BLUEPRINT
Start without an app
A three-part numbered paper delivery note and one trained site checker can validate the service before software exists.
04 / THE BLUEPRINT
Technology that could help
A secure mobile form can capture quantity, arrival time, agreed photos and signatures while offline, then export immutable copies for parties. Any geolocation must be optional, justified and protected.
05 / THE BLUEPRINT
Your first experiment
- Ask five small contractors about repeated delivery disputes.
- Agree with one supplier on a simple proof-of-handover template.
- Test five deliveries with consent using the supplier's normal acceptance policy.
- Compare errors discovered and minutes spent resolving disputes.

People, resources and cost drivers
Customers: contractors, merchants and logistics operators. Resources: trustworthy inspectors, training, phone, clear liability terms and privacy protection. Revenue: per-delivery verification or project retainer.
07 / THE BLUEPRINT
What to validate — and when to stop
Validate whether customers pay for fewer disputes; compare actual physical checks with signed records and count the cases resolved rather than mere photos uploaded.
08 / HYPOTHESIS TO TEST
Potential impact and how to measure it
Track reconciled deliveries, confirmed shortages, dispute-resolution time, processing cost and recurring customer contracts.
09 / THE BLUEPRINT
Risks and safeguards
A photo cannot verify hidden material quality or structural safety. Collusion, bribery, worker privacy and unsafe site access are risks. Follow site safety rules and keep independent records.
10 / THE BLUEPRINT
Who might pay or maintain it
Start with repeat low-risk deliveries and reliable suppliers, then add staff only as fees cover supervision, insurance and investigation costs.
