Developing and Launching Automation Software for the Largest Retail Chain in Ireland

A story about enterprise-grade finance automation: control, security, and measurable ROI

Enterprise automation projects rarely fail because the code is hard. They fail because the operating reality is hard.

In large retail, finance is a living system: thousands of daily transactions, multiple stores, multiple data sources, constant exceptions, and a month-end close that never slows down. One missing docket or one mismatched sales journal can ripple into disputes, delayed reporting, and costly manual rework.

This project started with a clear mandate: replace fragmented, manual finance workflows with a single automation platform that could support the scale and governance expectations of Ireland’s largest retail chain—without disrupting daily operations.

We partnered with a specialist retail finance operations team to design, build, and launch a platform that automated the workflows that matter most in multi-site retail finance: central billing, POS reconciliation, dockets, sales journals, invoices, exceptions, and reporting—while meeting enterprise expectations around security, auditability, reliability, and supportability.

The enterprise problem: finance operations don’t scale linearly

In a small business, manual reconciliation is annoying. In a national retail chain, it becomes a systemic risk.

A typical week looked like this:

• POS totals exported from multiple sources and formats

• Sales journals compiled and checked against store-level reports

• Dockets and supporting documents chased across teams

• Central billing reconciliations managed in spreadsheets

• Supplier invoices processed with inconsistent validation steps

• Exceptions handled via email threads and “tribal knowledge”

Even with a strong finance team, the real cost wasn’t only time. It was:

• Slow decision cycles (numbers arrive late or lack confidence)

• Higher error rates (manual handling, gaps in evidence, duplicates)

• Audit stress (hard to prove who changed what, when, and why)

• Operational drag (finance becomes a bottleneck for the business)

The goal wasn’t simply “automation.” The goal was a controlled, repeatable system that produced reliable outcomes.

What enterprise stakeholders demanded

This is where enterprise delivery differs from startup delivery. “Nice features” do not win; predictable outcomes do.

CFO / Finance leadership

• Faster close and higher confidence in numbers

• Stronger controls and fewer surprises

• Clear ROI: lower cost-to-serve finance operations

Controllers and finance operations teams

• Fewer manual steps and less spreadsheet dependency

• Standardized workflows across locations

• Clear exception ownership and resolution trails

IT and Security

• Least-privilege access and role separation

• Secure data handling, encryption, and monitoring

• Resilient architecture with operational readiness

Audit and Compliance

• Audit trails and evidence retention

• Consistent control execution with proof

• Change management and approval workflows

Our approach, architecture, and rollout plan were designed to satisfy all four groups simultaneously.

The approach: automate the workflow, not just the data

We didn’t start by designing screens. We started by designing flows.

We mapped the end-to-end lifecycle of retail finance operations:

1. Ingest: POS exports, sales journals, invoices, dockets, and supporting documents

2. Normalize: standardize formats, identifiers, store mappings, and timelines

3. Validate: rule checks, thresholds, mandatory fields, duplicate detection

4. Match & reconcile: align journals, transactions, and billing lines to expected totals

5. Exception handling: assign owners, collect evidence, resolve, approve, and track

6. Reporting: weekly reporting and management-ready visibility

7. Auditability: immutable trails across approvals, edits, and key control steps

Where it created meaningful value, we used intelligent automation (including LLM-assisted components for document handling and extraction). The principle was consistent: automation supports humans; it doesn’t remove control.

Milestone timeline: how we de-risked an enterprise rollout

Phase 1 — Discovery and control blueprint

We translated existing finance controls into a formal operating model:

• System-of-record definitions (what wins when sources conflict)

• Reconciliation rules and tolerances

• Exception taxonomy and routing

• Evidence requirements and retention expectations

Output: a control blueprint that defined how automation must behave under real-world conditions.

Phase 2 — MVP in a controlled scope (pilot-first)

Enterprises don’t need “more features.” They need proof it works in production.

We launched an MVP focused on the highest-frequency workflows:

• POS ingestion and normalization

• Automated journal preparation and validation

• Central billing reconciliation support

• Exception queues with ownership and resolution trails

Output: a pilot that reduced manual work without disrupting store operations.

Phase 3 — Scale across locations and workflows

Once the pilot proved stable, we expanded across breadth and volume:

• Additional POS feeds and variations

• Performance tuning and cost-aware processing

• Standardized multi-location reporting

• Broader invoice and docket workflows

• Deeper exception handling (rules + assisted resolution)

Output: a platform designed to handle enterprise scale and operational variability.

Phase 4 — Enterprise hardening: security, resilience, audit readiness

We treated “enterprise-grade” as engineering work, not marketing:

• Role-based access control and least privilege

• Secure secrets management and environment separation

• Encryption in transit and at rest

• Comprehensive audit logs for critical actions

• Monitoring/alerting and operational dashboards

• Backup strategy and recovery planning

Output: a system the business could rely on—and defend under security review and audit.

What we delivered (in business terms)

The platform became a single operational layer for retail finance automation, supporting:

• Central billing workflows and reconciliation

• POS reconciliation and back-office alignment

• Sales journals preparation, validation, and approvals

• Dockets and supporting evidence capture and linkage

• Invoices and accounts payable operations support

• Exceptions with ownership, SLA awareness, and full traceability

• Weekly reporting with consistent definitions and outputs

• Controls and compliance embedded into daily workflows

The result was a system that reduced dependence on ad-hoc spreadsheets and manual handoffs while increasing visibility and governance.

The stack (built for longevity and enterprise operations)

We delivered using a modern, scalable stack aligned with enterprise-grade delivery:

• Frontend: React (TypeScript / JavaScript)

• Backend: Node.js (TypeScript / JavaScript)

• Cloud: AWS (secure, scalable deployment patterns)

• Database: PostgreSQL

• Intelligent automation: LLM-assisted components where appropriate

The key wasn’t the stack alone—it was the operating characteristics it enabled: maintainability, auditability, performance, and controlled evolution.

Outcomes enterprises care about: ROI without hand-waving

Because each enterprise environment is different, we avoid generic “we saved 90%” claims. Instead, we measured outcomes in the ways enterprise finance teams actually track:

• Reduced manual reconciliation steps and spreadsheet dependency

• Faster exception resolution with clear ownership and evidence trails

• Increased standardization across locations (consistent rules and controls)

• Better audit readiness (who did what, when, why—available on demand)

• Improved reporting timeliness and confidence in numbers

For enterprise buyers, the ROI is straightforward: lower operational cost-to-serve finance controls, fewer errors, faster decisions, and reduced audit friction.

What this case teaches (if you’re an enterprise buyer)

If you’re evaluating automation for finance operations, don’t choose a vendor based on feature lists alone.

Choose a partner who can:

• Translate operational controls into scalable workflows

• Deliver safely via pilots and staged rollout

• Build security and auditability into the platform from day one

• Handle integrations and real-world variability without degrading reliability

• Support long-term ownership (documentation, maintainability, handover)

That’s how enterprise automation succeeds: predictable outcomes, strong controls, and a system that keeps working as the business grows.
