Core Banking System runs treasury instruction work for a banking organization: a preparer records the amount, counterparty, owner and debit and credit account scopes; an independent approver decides on the frozen revision; the team submits an authorized instruction and follows the provider's actual response. Operations Overview brings current exceptions into view for the team that owns them.

Click Get started, then use Proto to configure Core Banking System for your business. Begin with one organization, an active provider relationship, a few accounts and a rehearsed instruction through review and reconciliation.
An Independent Treasury Approver decides through the guarded action on the frozen revision. The preparer cannot approve their own submission.
It is confirmed after verified provider confirmation or settlement evidence is attached to the instruction. Submission and a provider reference identify work in progress.
Each financial account keeps its provider, external account identifier, currency, active state and counterparty owner. Debit and credit scopes link instructions to the accounts they affect.
The internal decision is recorded against the submitted revision. Completion follows only when the provider has actually authorized the account request.
The movement must agree with a confirmed instruction on the same account, exact amount and confirmed occurrence date. A difference remains open for investigation.
Use the guarded correction or cancellation route. Keep earlier review decisions and verified provider evidence, and check the provider's actual effect before treating a correction as final.
Inspect the operation receipt, provider reference and later evidence before deciding whether further action is needed. Completion verification reads recorded effects without sending the instruction again.
App Administrator maintains organization configuration and membership. That role does not carry independent approval or execution authority.
Auditor has scoped read-only access to the instruction, decisions, evidence, reconciliation items and operation receipts needed to inspect its history.
Start free, then use Proto to change fields, steps and approvals before your team goes live.
