What changed since the last supplier file?

A supplier schedule can still be useful even when it changes every week. The control problem is noticing which commitments moved, then deciding what those movements affect.

Supplier delivery schedule demonstration

See Houston identify an eleven-day change to a supplier delivery commitment.

Transcript will be provided with the final video.

Changes Houston can bring forward.

  • Delivery date moved
  • Quantity reduced
  • Purchase-order line removed
  • New line added
  • Status changed
  • Supplier reference changed
  • Duplicate commitment introduced
  • Date no longer supports the production requirement

From changed value to operational question.

Houston matches the records, shows the source evidence and separates certain changes from uncertain matches. Your team decides what the change means and what action should follow.

Decisions this version review can support

  • Check whether production can still start on 22 August
  • Confirm whether another supply line can cover the shortfall
  • Review the 5 September customer commitment
  • Ask the supplier to explain or reconfirm the movement
  1. 01

    Bring the file you already use

    Start with the spreadsheet already used by your team. Houston does not require an immediate migration into a new operational system.

  2. 02

    Upload the next version

    Houston matches the records and identifies additions, removals and changed values.

  3. 03

    Review what needs attention

    Filter the version review, inspect the evidence and decide what action should follow.

Start with one real file.

Send two representative versions of a recurring spreadsheet. Praxis Lab will help configure the first version review, examine the results with you and determine whether Houston would be useful as an ongoing control.

  1. Share two representative file versions.
  2. Identify what each row represents.
  3. Confirm the fields that matter.
  4. Run the first version review.
  5. Review the findings together.
  6. Continue only when the result is useful.

  • No ongoing commitment; cancel at any time
  • You retain ownership of your files and data
Discuss your file

Questions, answered carefully.

Do I need to change my spreadsheet?

Not necessarily. Houston starts with the file your team already uses. Some configuration may be needed so that records and important fields can be identified reliably.

Which spreadsheet formats are supported?

The first version-tracking setup is agreed with Praxis Lab after reviewing representative files. Standard Excel and CSV files are the intended starting point; confirm your particular format during setup.

Does Houston alter the original file?

No. Houston keeps the source evidence visible and does not silently edit either original file.

What happens when column names change?

Houston can be configured around expected fields. A changed or missing column is made visible for review rather than quietly ignored.

What happens when Houston cannot identify the same row?

It shows that the match is uncertain. A person can then inspect the evidence and decide whether the records belong together.

What does the £100 subscription cover?

The starting subscription tracks successive versions of one agreed recurring source, configured around its current structure. During setup, Praxis agrees the relevant worksheets, expected version frequency and intended users with you. A materially different layout or another recurring source is assessed separately before any change to scope or price.

Can Houston reconcile two different sources?

Potentially. Reconciliation is distinct from tracking successive versions of one source and needs its own agreed configuration. Praxis will confirm whether the proposed sources can be matched meaningfully.

Try Houston with one of your files.

Tell Praxis about the recurring file and the change you need to see. Do not attach confidential files here; a secure way to review representative versions can be agreed afterwards.

Your details are stored privately by Praxis Lab so that we can respond. No file is uploaded.
