From two exports to billing ready for review

Each month, the team had to combine several files and rules before it could prepare client billing. We built a system that guides them through five clear steps and shows what still needs review.

The client's name and business data are not disclosed. This case study describes the architecture of an active implementation without invented savings or financial results.

01 / Problem

Each month, the team had to manually assemble data from several files.

Each billing run required accounting data, a record of completed work and client-specific rules. The team had to locate, connect and verify all of it.

If a file was missing or a client name did not match, it was difficult to quickly identify the issue and who needed to resolve it.

How the work was done before5 steps
  1. 01

    Find the required files

  2. 02

    Check which client they belong to

  3. 03

    Add completed work and special rules

  4. 04

    Find missing or incorrect data

  5. 05

    Prepare the final document manually

02 / What we wanted to achieve

We wanted the system to prepare the data, clearly flag errors and leave the final decision to a person.

03 / Solution

The system now guides the data from the first file to billing ready for review.

Instead of one large, opaque process, the solution has five simple steps. At each step, it is clear what happens and what a person still needs to review.

How the solution works5 steps
  1. 01

    Finds the files

    Checks whether the correct files for the correct month are present.

  2. 02

    Identifies the client

    Matches each record to the correct client.

  3. 03

    Applies the rules

    Accounts for completed work and the specific rules that apply to the client.

  4. 04

    Flags issues

    If anything is missing or does not match, the system clearly flags it for review.

  5. 05

    Prepares the PDF

    The final document is generated only after the accountable person approves it.

Where a person reviews the work

  • rules for each client are stored in one place
  • the system flags an incorrect month or a missing file
  • what happened is visible for each client
  • a person approves the billing before the PDF is generated

04 / Result

The team now has a clear process instead of assembling everything manually from memory.

The system prepares the repetitive part of the work and shows where it needs help. The team no longer searches for errors blindly.

Every issue receives a clear status, while the final document is still approved by the accountable person. Automation supports the work without assuming responsibility.

Process components5 steps

Each step has one clear task: from reading the files to preparing the final document.

Final reviewBefore PDF generation

The document is generated only after the accountable person reviews and approves it.

Work overviewClear status

The team can see what is complete, what is missing and where a person is needed.

What changed for the team

  • less manual copying between files
  • errors are visible and do not remain hidden
  • each billing run has a clear status
  • a person still approves the final result

05 / Important considerations

What needs to be considered.

  • We do not present time or cost savings because they have not been publicly verified.
  • If the input files are incorrect, a person still needs to resolve the issue.
  • The system prepares the billing, but does not approve it on behalf of the accountable person.

Case study: We show how the system works and where a person reviews the result. We do not state time or cost savings because they have not yet been publicly verified.
