Source-to-Retire (S2R)

What is Source-to-Retire?

Source-to-Retire (S2R) is the most complete procurement category in enterprise software. It begins at vendor discovery and onboarding, runs through requisition, RFQ, purchase order, goods receipt, three-way matching, and payment — and then continues through asset registration, depreciation, maintenance, audit, transfer, and final disposal or retirement.

Three closely-related categories sit inside S2R but each stops short of the full lifecycle:

• P2P (Procure-to-Pay) — requisition through payment. Stops at the invoice.
• S2P (Source-to-Pay) — adds vendor sourcing in front of P2P. Still stops at the invoice.
• P2R (Procure-to-Receipt) — adds asset registration after payment, but no lifecycle management.

S2R is the only category where the same database tracks an asset from the moment a vendor is qualified to the moment that asset is auctioned for scrap years later.

Why S2R matters in India

India's regulatory and tax environment make the post-payment portion of the lifecycle just as compliance-heavy as the procurement front. A few examples:

• Companies Act 2013 — every company must maintain a fixed asset register with location, useful life, and depreciation method per Schedule II. The register must reconcile to the books at year-end.
• CARO 2020 — the statutory auditor must report on physical verification of fixed assets, encumbrances, and disposal-year material adjustments. CARO 2020 Clause 3(i) is unhappy with companies that cannot show a year-round audit trail.
• IND AS 16 component accounting — for companies on the Ind AS roadmap, every major component of an asset (e.g. an aircraft engine vs the airframe) is depreciated separately. IND AS 16 derecognition rules apply on disposal — and they need a clean derecognition entry.
• GST input-credit reconciliation — the credit can only be claimed on goods actually received. GSTR-2A/2B must reconcile against the goods receipt, three-way match, and asset register entry. Mismatches across three different systems are the most common ITC reversal trigger.
• CPCB e-waste rules — at end-of-life, IT and electronic assets must be channelled through authorized recyclers with chain-of-custody documentation. The disposal record links back to the original purchase order — a P2P-only system breaks this trail.
• SEZ / STPI bonded operations — every imported asset has a bond closure obligation. Without lifecycle tracking from PO to disposal, bond closure becomes a manual reconstruction project.

An S2R platform is the only architecture where these obligations are satisfied by-product of the daily workflow rather than as a separate audit project.

How ProcurePulse delivers S2R

ProcurePulse runs the full S2R cycle as one application on one database:

• Sourcing — vendor portal, RFQ, e-auction, vendor evaluation
• Procurement — purchase requisition, PO, GRN, three-way matching
• Finance — invoice, payment, GST/ITC + GSTR-2A/2B reconciliation
• Asset register — auto-created from GRN with Schedule II asset class, useful life, and depreciation method pre-filled
• Lifecycle — allocation, transfer, gatepass, AMC, maintenance, repairs, audit (VTR)
• Retirement — disposal proposal → reverse auction → recycler chain-of-custody → derecognition entry → CARO/IND AS evidence pack

The platform is the only place where you can trace any asset from "PO 2018-04-0123" through to "Disposed via reverse auction 2026-Q1, ₹84,000 recovered" with every entry between fully auditable.

What changes when you adopt S2R

• The asset register is no longer a quarterly reconciliation project — it updates itself from procurement events
• Depreciation runs on a single source of truth — no more reconciling tally between SAP-MM and the fixed-asset spreadsheet
• Disposal becomes an income line — reverse auctions consistently recover 40–60% of book value vs the 10–20% from local scrap quotes
• Audits run on real-time data instead of frozen extracts — auditors can self-serve evidence, finance teams stop building data packs
• Vendor performance reviews include not just delivery and quality, but post-deployment failures (warranty, AMC, MTBF) — closing the feedback loop
