Settling a PPA means matching metered output to contract terms, prices, and curtailment rules across plant, ERP, and counterparty systems. Here is where the match fails. 01 - Spreadsheet settlement ### Every cycle is rebuilt by hand Analysts pull inverter output, paste it next to PPA terms in Excel, and compute settlement manually. One transcription error and the counterparty invoice is wrong before it ships. RELIABILITY 02 - Contract logic drift ### Each PPA prices differently Floors, ceilings, escalators, and curtailment compensation differ per contract in SAP S/4HANA. Hand-coded math falls out of sync the moment a term is amended. SCHEMA 03 - Double-counted output ### One replay, two settlements A re-sent generation file or a retried sync can settle the same interval twice. Without idempotency the counterparty is overpaid and finance unwinds it the next cycle. IDEMPOTENCY PLATFORM ## Six products. One Platform. Replace many legacy vendors.

The concerns trading and finance teams raise before automating PPA reconciliation and invoicing. [Talk to a solutions architect](https://www.stacksync.com/book-a-demo) ### How is generation reconciled against contract terms? Inverter and OSIsoft PI output streams in, then Stacksync applies each PPA's pricing, floors, ceilings, and curtailment rules from SAP S/4HANA to compute settlement, with the math living in config, not a spreadsheet. ### What happens when a PPA term changes? You amend the term in one place and the settlement logic follows. Because pricing rules are declarative, an amendment is a config update rather than re-coding the calculation. ### How do you prevent settling the same output twice? Writes are idempotent, keyed on asset plus interval. A re-sent generation file or retried sync updates the existing settlement instead of paying the counterparty twice. ### Are counterparty invoices issued automatically? Yes. Once an interval settles, Stacksync writes the invoice into NetSuite or SAP S/4HANA two-way, so the counterparty is billed without an analyst rebuilding the cycle. ## Stop settling PPAs in Excel. Reconcile and invoice automatically. [Book a demo](https://www.stacksync.com/book-a-demo) [Get started](https://app.stacksync.com/)
