Finance operations software should make a proposed allocation, its supporting documents and the approving person's decision visible. A matched amount is useful evidence, but it does not by itself prove that the correct customer, invoice, currency or accounting period has been selected.
This guide concerns software controls for document review, payment allocation and reconciliation exceptions. The workflow and amounts are hypothetical. An accountable finance professional should determine accounting treatment, tax handling and period-close rules for the business.
Define records and decision ownership
List the documents the team handles: invoices, credit notes, payments, statements and adjustments. Give each a stable source identifier. Record which system owns the original and which system receives a reviewed copy or status update.
Separate document capture, matching suggestions, approval and posting. A model may extract a reference or propose a match, but a configured rule or authorized reviewer decides whether an action is permitted. Identify who may approve each action and who can reverse it.
For multi-organization software, isolation is a release requirement. A user must not see or act on another organization's records. Test permissions at the server boundary and through exports, search and attachments; a filtered screen is insufficient protection.
Specify what a matching suggestion contains
Show the original amount and currency, document references, dates, current balances and why the candidate was proposed. Include any conflicting evidence. The reviewer should not need to trust an unexplained confidence number.
Define partial, combined and excessive payments as separate cases. Avoid forcing every receipt into a one-payment, one-invoice shape. If source data is incomplete, preserve an unresolved item with an owner rather than inventing a reference.
Xero's Payments API distinguishes applying payments to invoices from reversing payments and recording related transactions. Its payment-processor guidance also discusses aggregate settlements. These are examples of the distinctions an integration must preserve; they are not a prescribed accounting policy. Xero Payments API, Xero payment-processor receipt guide
Work through a hypothetical unmatched receipt
Suppose an operator reviews a €980 receipt and two open invoices for the same customer: €600 and €400. The system proposes both invoices, but the total differs by €20. That difference should remain visible.
The reviewer checks the source documentation and asks the finance owner to determine whether the difference reflects a fee, a short payment, an unrelated adjustment or an incorrect match. The software must not silently label the €20 as a fee to make the totals fit.
The review screen can record the proposed allocation, unresolved difference, supporting documents and decision. If approval is withheld, the receipt stays in the exception queue. If an authorized decision is made, preserve the decision and any resulting external references.
Now repeat the receipt import. The system should recognize the source item and avoid adding another payment. Then reverse an approved allocation in the test environment. The original record, reversal and resulting balances should remain traceable.
Design review and reversal as normal paths
Create an exception queue that explains the next action: missing document, conflicting customer reference, duplicate source item, currency mismatch or required approval. Give each item an owner and a status that distinguishes waiting from completed work.
Keep an audit history containing the actor, time, previous state, new state and reason for the decision. Apply appropriate access and retention rules. Logs should help trace the action without becoming an uncontrolled duplicate of sensitive documents.
Define a reversal procedure with the finance owner. Avoid deleting the history of a completed action to imitate a clean result. When an external accounting system is involved, confirm what its API actually permits and how the operator reconciles a failed or uncertain response.
Test an unauthorized approval attempt, an expired session, a disconnected provider and an action repeated after timeout. The interface should explain whether the result is rejected, pending or uncertain. Staff need a recovery procedure that does not risk posting the action twice.
Set a bounded acceptance exercise
Use synthetic records agreed with the finance owner. Include a straightforward payment, partial payment, combined receipt, duplicate import, missing invoice, currency mismatch and reversal. Compare source totals and reviewed results using the owner's approved rules.
Acceptance should demonstrate correct permissions, traceable decisions, recoverable failures and clear exception ownership. Measure review effort and unresolved items during an authorized pilot. A dashboard total alone is insufficient evidence of correct bookkeeping.
Keep bank feeds, tax filing, payroll and statutory reporting outside the first scope unless separately designed and approved. Provider connectivity and production controls must be demonstrated before staff rely on the system for live work.
KasaFlow is BrainGlow's invoices, allocation, reconciliation and period-review foundation. It requires accountant-led acceptance, isolation review and production hardening. Bank and tax integrations are excluded from its proposed pilot scope.

Discuss a finance review workflow with anonymized document types, decision roles and the acceptance cases your finance owner requires. Keep accounting policy decisions with the responsible professional throughout the project.
