Case study · Qatar
How Qatar’s General Tax Authority assesses returns faster on SAP TRM
SAP TRM helps the GTA review and assess the declarations its taxpayers file, while keeping pace with frequent changes in legislation.
Our eBook, by tax consultant Sahil Sidhwani, explains how a standard SAP product was configured to stay flexible as the law kept changing.

Our accelerators
Built by Invenio
Three things we made because the standard product didn’t close the gap.
Pre-built revenue-authority configuration across registration, filing, assessment and audit: the processes that are substantially the same in every jurisdiction, so the programme spends its time on the ones that aren’t.
A pre-programme that settles deployment model, scope and business case before the budget is committed.
Enablement for the authority’s own staff. Long tenures and low technology use inside an authority are a real brake on change, and the people who will run the platform for the next decade are usually the last ones funded.
Accelerators shorten the common part of a programme. They are not a product, and we don’t present them as one.

Is your tax platform keeping up?
A structured review of your current tax platform: what it does well, where the next pressure comes from (a new tax type, a legislative deadline, an upgrade) and what we would do, in what order. No pitch deck required.
- We reply within two working days to set a call.
- A 60-minute review with your platform and policy leads.
- A written summary and a recommended sequence.
A tax platform outlives the programme that built it. The question is usually not whether it works, but who will still be there when the law changes.
