A $2.8 billion advertising services company faced a familiar post-merger problem: more than 70 agencies, multiple financial systems, inconsistent processes, and a growing volume of manual finance work. This finance shared services automation case study shows how the organization used RPA, AI document intelligence, workflow orchestration, and anomaly detection to create a standardized automation layer across its agency network.
Instead of forcing every acquired agency onto one system, the company connected existing platforms and automated high-volume finance and operational workflows. The result was 9,700 hours recovered annually, a 97% reduction in reconciliation errors, a 62% faster financial close, and the ability to integrate three additional agencies in under seven days each—all without proportional headcount growth.
Post-merger integration becomes significantly more difficult when acquired companies continue operating with their systems, processes, and data structures. That was the reality for this $2.8 billion advertising services organization after bringing more than 70 agencies across North America, EMEA, and APAC under one corporate network.
Each agency had its own financial stack, project management tools, reporting cadence, and operating practices. Finance teams were required to consolidate information from multiple ERP environments and other business applications, often relying on spreadsheets and manual data transfers.
The problem extended beyond traditional accounting activities.
Employees manually collected and processed time logs, vendor invoices, purchase orders, creative briefs, and other operational documents. Finance teams then reconciled information between systems before month-end close. Differences in formats, missing information, duplicate entries, and inconsistent data created exceptions that required manual investigation.
The consequences accumulated quickly:
The organization ultimately needed more than isolated task automation. It needed a shared services transformation capable of standardizing workflows while allowing individual agencies to retain their existing applications.
This made post-merger automation a strategic requirement rather than simply an IT efficiency project. The objective was to create a common automation layer that could connect different entities, systems, and processes without requiring a disruptive rip-and-replace technology program.
The company implemented an intelligent automation architecture designed to operate across its existing agency systems. Rather than replacing every ERP or forcing agencies onto a single platform, the solution created an automation layer that connected applications and standardized the movement of information between them.
The architecture combined unattended RPA bots, AI-powered document intelligence, workflow orchestration, and anomaly-detection agents.
Unattended bots extracted financial and billing information from different ERP systems on a scheduled basis. The data was normalized into a consistent structure before being reconciled against the central financial environment.
Instead of waiting for finance teams to manually identify differences, the automation layer flagged exceptions for human review. Standard transactions could continue through the workflow automatically, while unusual or incomplete records were routed to the appropriate team.
This created a practical model for cross-entity finance automation: different entities could continue using their existing systems while the shared services environment received standardized financial information.
AI document intelligence was introduced to process invoices arriving in different formats, including unstructured PDF documents.
The AI layer extracted relevant fields such as vendor information, invoice numbers, amounts, dates, and purchase-order references. Once validated, approved transactions could be routed to the appropriate agency ERP.
This reduced repetitive data entry and helped finance teams focus their time on exceptions rather than manually entering every invoice.
Unattended bots collected employee time logs from multiple project management platforms. The information was validated, standardized, and routed to the central payroll and client-billing processes.
This was particularly important in an agency environment where employee time can affect both internal workforce reporting and client billing.
The automation model also extended beyond conventional finance transactions.
AI-driven workflow orchestration processed creative briefs, assets, project milestones, and approvals. When predefined conditions were met, the system automatically triggered the next stage of the workflow and delivered the required information to downstream teams.
Anomaly-detection agents provided another layer of intelligence by identifying unusual records and exceptions instead of treating every transaction the same way.
Together, RPA and AI created a more flexible form of RPA finance automation. Bots handled predictable, repetitive activities, while AI helped interpret documents, identify anomalies, and route exceptions.
The architecture was deliberately designed for scale. New agencies could be connected to the automation layer without requiring the entire network to standardize on one ERP or operational platform.
This approach allowed the company to preserve agency-level autonomy while creating standardized processes at the shared-services level.
The result was an automation model that could expand as the organization acquired additional businesses—turning automation into part of the post-merger integration framework rather than a one-time technology project.
The organization also gained greater visibility across its agency network. Standardized data flows made it possible to develop consolidated reporting and compare performance across agencies.
The impact extended beyond finance. With repetitive reconciliation and data-processing work automated, teams could redirect capacity toward analysis, forecasting, and other higher-value activities.
Most importantly, the automation framework became reusable. When three additional agencies joined during the rollout, each could be integrated into the automation layer in less than seven days—far faster than the previous manual onboarding approach.
For global business services and shared services leaders, this case demonstrates why automation should be considered during post-merger or post-acquisition integration—not after integration is complete.
When organizations acquire multiple entities, the immediate temptation is to standardize technology first. In reality, forcing every entity onto one ERP or application stack can take years and may delay the realization of merger synergies.
A better approach can be to establish a standardized automation layer across existing systems.
This is where shared services automation becomes valuable. Automation can standardize how information moves between entities without requiring every entity to use identical technology.
For GBS organizations, this approach creates several advantages:
The broader lesson is that shared services transformation does not have to mean immediate system consolidation. Organizations can first standardize processes, data flows, controls, and automation while allowing legacy systems to remain in place.
For organizations managing frequent acquisitions, this becomes especially important. A reusable automation framework that includes reconciliation automation can become part of the M&A integration playbook, reducing the effort required every time another entity joins the organization. This helps standardize financial processes, improve data accuracy, and accelerate integration across newly acquired entities.
This approach also complements broader finance shared services strategies, where the objective is to move finance from fragmented transactional processing toward a centralized, scalable operating model.
Organizations considering post-merger automation should avoid attempting to automate every process simultaneously. A focused, process-first approach is usually easier to implement, measure, and scale.
Step 1: Map the post-merger processes
Identify where different entities perform the same activity differently. Focus on finance processes involving high transaction volumes, repetitive manual work, and frequent exceptions.
Step 2: Identify automation candidates
Prioritize processes such as reconciliation, invoice processing, data consolidation, reporting, time-log validation, and financial close activities.
Step 3: Standardize before automating
Document the common rules, required data, approval paths, and exception conditions. Automation should not simply reproduce inefficient processes.
Step 4: Build the automation layer
Use RPA for structured, repetitive work and AI for unstructured documents, classification, anomaly detection, and exception handling.
Step 5: Measure and scale
Track processing time, error rates, close-cycle duration, manual hours, and onboarding time. Once the first workflow is stable, reuse the architecture for additional entities and processes.
Organizations can also explore finance transformation consulting to identify high-value opportunities and create a roadmap for scaling automation across the finance function.
Post-merger complexity does not have to mean more spreadsheets, more manual reconciliation, and more finance headcount. A standardized automation layer powered by intelligent enterprise automation and agentic process automation can help organizations connect different entities, systems, and processes while creating a scalable foundation for finance and GBS operations.
Book a discovery call to identify high-impact automation opportunities across your finance and shared services environment.
Yes. Automation can connect finance systems across acquired entities, standardize data flows, automate reconciliation, process documents, and route exceptions. This allows organizations to improve integration without immediately replacing every underlying system.
The approach is particularly useful when acquired companies operate different ERPs, project management platforms, and financial processes.
RPA bots can interact with multiple applications based on predefined workflows. For example, bots can extract data from different ERP systems, validate records, transform information into a standardized structure, and send the results to a central finance environment.
A centralized orchestration layer can manage bots across entities while maintaining entity-specific rules where necessary.
The timeline depends on the number of entities, processes, systems, integrations, and automation complexity.
A phased approach is generally more practical than attempting a network-wide transformation at once. In this case, the implementation used discovery, development, integration, and staged rollout phases, while three additional agencies were subsequently integrated in under seven days each.
Common candidates include:
Organizations can also extend automation into adjacent operational processes once core finance workflows are stable.
Traditional RPA is effective when rules and data structures are predictable. AI can add flexibility by interpreting unstructured documents, identifying unusual transactions, classifying information, and detecting anomalies.
When AI and RPA work together, routine transactions can be processed automatically while unusual cases are escalated to humans for review. This can make reconciliation automation more adaptable across entities with different data structures.
The major benefits include reduced manual effort, fewer processing errors, faster financial close, standardized workflows, improved visibility, and faster onboarding of new entities.
For organizations pursuing acquisitions, the biggest advantage may be scalability. A reusable automation framework can help absorb additional entities without requiring the shared services organization to increase headcount at the same rate.
This is also where intelligent enterprise automation and agentic process automation can extend the model beyond traditional rule-based RPA.
