# Installation contractor: weekly report from three sources

## Reconciliation made visible instead of hidden

Compile a weekly operational overview from planning, time tracking and invoicing, showing differences between sources as a separate list.

## Where it began

The pattern described by this case: three systems describe the same work from different angles. Planning says what was supposed to happen, time tracking what was done, invoicing what was charged. Anyone making a weekly overview exports all three and compares them — then spends most of the time explaining the differences.

What makes automation tempting is also what makes it dangerous here: a system that combines the three sources into one tidy number removes exactly the information the overview was meant to provide.

## What we built

This type of workflow reads the three sources, compiles the overview and keeps the differences separate. The report has two parts: the figures the sources agree on, and a list of items where they diverge — with each source's value and a reference to the underlying record for every item.

That second list is the real product. A difference between planned and recorded hours is a signal about the work, not a report error. It should reach the work planner instead of disappearing into a total.

## Where people stayed involved

The workflow is read only. Nothing is changed in any of the three source systems; the report is derived and makes no corrections to the records. Resolving a difference remains human work, in the system where it belongs.

For each run, the log records which sources were read and when. This makes a report traceable: a figure that differs from what someone sees in a source system is almost always due to a different reading time, and without that detail the discussion goes on for a long time.

The underlying workflows are described under [the weekly operations report](<https://gen8.app/en/mogelijkheden/weekrapport-operations/>) and [compiling management reports](<https://gen8.app/en/mogelijkheden/managementrapportage/>), with sector context under [construction and logistics](<https://gen8.app/en/sectoren/bouw-en-logistiek/>). Other [cases](<https://gen8.app/en/cases/>) follow the same structure.

## What it achieved

This customer has not yet approved the measurable outcome for publication. Once that happens, the results will appear here.

## Does this look like your process?

Bring it to a conversation. We assess whether the same approach fits and where the differences lie.
