Best Practices for Accounting Integrations: Execution and Sustainability

In Best Practices for Accounting Integrations: Strategy and Control, we outlined the foundations of integration design from a finance perspective: defining requirements, standardizing mappings, ensuring reconciliation and traceability, and accounting for the strengths and shortcomings of the systems being connected.  Those principles provide the blueprint.  But for association finance teams, the value of an integration is proven in daily execution.

This article focuses on execution and sustainability, the practices that ensure integrations operate reliably through each close, support reconciliations, and adapt as systems and requirements evolve.

Test with Accounting Scenarios, Not Just Data Samples

Technical testing ensures data moves, but accounting testing ensures it moves correctly.  Successful testing begins with preparation, not execution.  A disciplined UAT process includes:

• Defining test objectives: identifying the financial assertions to be validated, such as revenue recognition timing, A/R balances, or intercompany balancing.

• Developing test scripts: creating step-by-step instructions that simulate real accounting workflows, including edge cases and exception handling.

• Identifying required data sets: selecting transactions that reflect the full spectrum of activity, from routine items to unusual or complex cases.

• Assigning roles: finance staff execute the accounting scenarios, IT monitors system performance, and project managers coordinate progress and track defects.

Once prepared, execution should validate transactions against real-world accounting scenarios, such as:

• Membership dues billed in December but recognized over the next 12 months.

• An event cancellation that requires reversing deferred revenue and refunding cash.

• A credit card chargeback that reduces cash but leaves the original order intact.

• A multi-entity transaction where proper due-to/due-from entries are created to keep each entity in balance.

Each test should conclude with reconciliation: general ledger balances must tie back to sub-ledgers and source systems, and exceptions must be logged and resolved before go-live.  UAT is not just about proving the integration runs, it is about proving the accounting holds up under real operational conditions.

Plan and Execute Cutover Carefully

Cutover is the point when an integration moves from testing to production.  Even with thorough testing, there is always risk when transitioning to live data and processes.

Timing of the cutover is critical, with the best practice being to align it with a period close.  This creates a clear break between old and new processes, ensures that balances are reconciled at the transition point, and minimizes the risk of transactions being split across two posting methods.

A cutover plan should include:

• Freeze points: the point at which no further changes are made to code, mappings, rules, or test scripts.

• Data validation: confirming that opening balances in the GL tie to sub-ledger positions at cutover.

• Fallback procedures: predefined steps if issues arise during the first production run.

• Communication: making sure finance, IT, and business users know when the integration will go live and what to expect.

Disciplined cutover planning ensures that the integration begins with clean, auditable balances and reduces the risk of confusion during transition.

Monitor with Dashboards and Alerts

Even the most carefully designed integrations encounter exceptions.  A missing account mapping, a miskeyed or unselected GL dimension in the transaction source system, or an unforeseen source system processing issue can all prevent transactions from posting cleanly.  Ongoing monitoring is essential to keep finance in control when these issues arise.

Best practice includes:

• Dashboards that show posting status, errors, and reconciliations in progress.

• Alerts that notify finance when transactions fail to post, when products are created in the source system without complete accounting attributes, or when transaction patterns appear unusual.

• Exception queues where finance can review, approve, or correct items before they enter the GL.

Monitoring ensures that integrations remain transparent, well-governed processes rather than opaque pipelines.

Govern Through Change Management

Transaction systems rarely stay static.  APIs are updated, regulations shift, and business practices evolve. Each of these changes can impact how data flows into the general ledger.  Without a governance process, integrations can drift out of alignment and introduce errors that are costly to trace and correct.

A strong change management approach starts with acknowledging the range of potential changes:

• Regulatory requirements: for example, the need to collect and account for sales tax in a new region.

• Payment processing updates: adding or replacing payment types such as ACH, credit cards, or digital wallets.

• Product and pricing changes: new offerings or adjustments that affect how revenue and discounts are mapped.

• System API updates: changes to the way data is exposed or structured, which can disrupt existing integrations.

From a project management perspective, every change should pass through a defined review process.  Finance is responsible for validating the accounting logic, IT ensures the technical implementation is sound, and project management coordinates the approval, testing, and communication.  Documentation should be updated with each approved change, and mappings or posting rules should be versioned so that history is preserved.

Effective change management ensures that integrations remain accurate and auditable, even as the systems and requirements they support continue to evolve.

Sustain with Continuous Review and Improvement

Integrations are not “set and forget.”  Even when they function reliably, finance leaders should view them as living processes that can be refined over time.  Periodic reviews serve two purposes: validating that integrations remain accurate and audit-ready, and identifying opportunities for improvement.

Reviews should confirm that reconciliations are still efficient, posting rules align with the current close process, and mappings reflect any new products or updates to the chart of accounts.  They should also evaluate whether exception handling can be streamlined, whether reporting visibility can be enhanced, and whether automation opportunities have emerged as operations evolve.

Approaching reviews as both validation and improvement keeps integrations resilient, efficient, and aligned with the organization’s financial needs.

SoundPost Bridge in Practice

SoundPost Bridge was designed with sustainability in mind.  Finance teams control posting rules and schedules, while dashboards and alerts make exceptions visible in real time.  Built-in governance tools ensure that changes in products or mappings are reviewed before they affect the GL.  And with reconciliation and versioning baked into its architecture, Bridge continues to provide clean, auditable financials as systems and requirements evolve.

Closing Notes

For association finance teams, integrations succeed only when they sustain confidence in financial reporting over time.  By testing against real accounting scenarios, planning disciplined cutovers, monitoring activity with transparency, governing through structured change management, and refining integrations through continuous improvement, finance leaders can ensure that data flows into the general ledger with accuracy and consistency.

Well-executed integrations reduce surprises at close, streamline reconciliations, and free finance teams to focus on analysis and strategic guidance rather than error correction.  In an environment where associations rely on multiple transaction systems, reliable integrations are not just technical assets.  They are essential tools for maintaining financial clarity and supporting organizational decision-making.
