Acquire-to-Retire(A2R)
From capex request to scrapping: how the acquire-to-retire process runs, how it is measured and where assets are capitalised late, valued wrongly or forgotten.
Also known as: A2R · Acquire to Retire · Acquire-to-Dispose · Asset lifecycle · Fixed asset lifecycle
What is Acquire-to-Retire?
Acquire-to-retire (A2R) is the end-to-end process covering the full lifecycle of a fixed asset – from the capital expenditure request through acquisition, capitalisation and operation to sale or scrapping. It links investment planning, procurement, asset accounting and maintenance: a machine is requested and approved, collected as an asset under construction, capitalised, maintained and depreciated for years and finally retired. Because each of these stages sits in a different function, A2R decides whether the asset register, depreciation and capex budget actually fit together.
Starts with
A need for a capital investment is requested.
Ends with
The asset has been disposed of and removed from the asset register.
Typical phases
- 1
Investment planning & approval
Departments request investments, which are checked against the budget and approved over several levels depending on the amount.
- Capex request created
- Business case reviewed
- Investment approved
- Budget released
- 2
Acquisition & capitalisation
The asset is acquired through a purchase order or built in-house. Costs first collect on an asset under construction and are capitalised as a fixed asset once it is put into service.
- Purchase order placed
- Costs on asset under construction
- Put into service
- Asset capitalised
- 3
Operation & maintenance
In operation the asset is serviced and repaired. Major measures can increase its value and have to be capitalised subsequently.
- Maintenance plan created
- Maintenance order
- Breakdown reported
- Subsequent capitalisation posted
- 4
Depreciation, revaluation & transfer
Scheduled depreciation runs every period, complemented by impairments, revaluations and transfers between cost centres, sites or legal entities.
- Depreciation run
- Asset inventory count
- Revaluation
- Asset transfer
- 5
Retirement
At the end of its useful life the asset is sold, scrapped or decommissioned, the remaining book value is written off and the disposal is documented.
- Decommissioning requested
- Disposal approved
- Sale or scrapping
- Asset retired
Business objects and systems
These are the objects the process leaves in the source systems – with timestamps, owners and relationships to each other.
- Capex request
- Requested investment with justification, amount, budget item and approval levels.
- Purchase order
- Procurement of the asset or its components – the bridge to purchase-to-pay.
- Asset under construction
- Collector for costs until the asset is put into service, then settled to a fixed asset.
- Asset master record
- The capitalised asset with acquisition value, useful life, location and cost centre.
- Maintenance order
- Servicing or repair at the functional location, with material, labour and downtime.
- Asset transaction
- Acquisition, depreciation, transfer or retirement as a posting in asset accounting.
Typical source systems
- ERP asset accounting (e.g. SAP S/4HANA Asset Accounting, Oracle Fusion Assets)
- Maintenance systems (e.g. SAP PM, IBM Maximo)
- Investment and project controlling (e.g. SAP PS)
- Procurement systems and asset inventory
KPIs that can be measured
- Capex request cycle time
- Time from request to final approval.
- Time to capitalisation
- Time from putting an asset into service to capitalising the asset under construction.
- Age of open assets under construction
- How long costs sit on assets under construction without being settled.
- Budget adherence
- Deviation between the approved amount and the actual acquisition cost.
- Unplanned maintenance
- Share of breakdown-driven orders among all maintenance orders of an asset.
- Disposals without approval
- Retirements that are not preceded by the required approval.
Typical problems
Assets under construction that are never finished
Assets that have long been in use remain as assets under construction. Depreciation starts too late, and the register does not show what is actually in operation.
Procurement bypassing approval
Purchase orders are placed before the investment is approved, or amounts are split across several requests to stay below approval limits.
Maintenance and accounting know different assets
Functional location and asset master record are not cleanly linked. Modifications and value increases do not reach asset accounting, or only at the inventory count.
Ghost assets in the register
Scrapped or sold assets are not retired and keep being depreciated, while the disposal is only visible in the warehouse or in maintenance.
How Noreja analyses Acquire-to-Retire
An asset has no single case that a flat event log could represent. It comes with a capex request, several purchase orders and invoices, an asset under construction, dozens of maintenance orders over the years and a depreciation posting every period. Noreja connects these objects in the event knowledge graph, so a late capitalisation, for example, can be traced back to a delayed invoice or a missing commissioning notice.
The expected order – approval before purchase order, capitalisation after commissioning, approval before disposal – is modelled with domain knowledge from asset accounting and maintenance. Deviations then show up as concrete breaches of the intended flow, not as just another variant among many.
Questions Noreja answers
- Which assets under construction have not been capitalised since they were put into service?
- Where were purchase orders placed before the investment was approved?
- Which approval levels extend the cycle time of capex requests the most?
- Which assets cause an above-average number of unplanned maintenance orders?
- Which assets have physically left the company but are still in the register?
- Where does the actual acquisition cost deviate from the approved amount?

Frequently asked questions about Acquire-to-Retire
What is the acquire-to-retire process?
Acquire-to-retire (A2R) is the end-to-end process for the lifecycle of a fixed asset. It runs from the capex request through acquisition, capitalisation, maintenance and depreciation to the sale or scrapping of the asset.
What is the difference between acquire-to-retire and purchase-to-pay?
Purchase-to-pay describes procurement from purchase requisition to payment, regardless of what is bought. Acquire-to-retire uses this path to acquire an asset, but starts earlier with the capex request and then follows the asset through its entire useful life until disposal.
Which KPIs matter in acquire-to-retire?
Typical KPIs are the cycle time of capex requests, time to capitalisation, the age of open assets under construction, budget adherence, the share of unplanned maintenance and disposals without approval.
Can process mining be used in asset management?
Yes. Capex requests, purchase orders, asset transactions and maintenance orders leave timestamps and owners in the ERP and the maintenance system. Process mining shows where capitalisations stall, approvals are bypassed and the asset register drifts away from reality.
