How Aider enabled efficient accounting operations for a global financial services network

A critical period of change for finance operations

The turning point: AIDER’s international one-stop-shop model

An established global shared services network serving a major international financial group faced a key internal transformation. With changes underway in its in-house accounting team, the company needed a reliable external partner to ensure continuity of core accounting processes while internal reorganization was in progress.

The challenge was clear: maintain uninterrupted handling of financial operations - especially accounts payable and bank statement processing - through a period of structural change without compromising quality or compliance.

AIDER helped the customer with:

- The client used the Symfonia accounting platform. Aider Group’s specialists were already proficient in this system, ensuring a smooth transition with minimal onboarding time. Technical challenges were resolved internally by the Aider Group team, enabling uninterrupted bookkeeping throughout the engagement.
- Aider Group transitioned responsibility for:
  
  Posting purchase invoices, and
  
  Processing bank statements
  
  through a structured four-stage implementation:
  
  Initial process analysis — Thorough review of existing procedures to identify improvement opportunities.
  
  Formal responsibility transfer — Aider Group took official ownership of the processes with appropriate system access.
  
  Transitional support period — Close collaboration with the internal team during a two-week onboarding phase.
  
  Optimization and quality monitoring — Regular reviews and internal audits to ensure alignment with agreed standards.
- During operations, Aider Group discovered inconsistencies in the client’s master data - including duplicate vendor and customer accounts that posed a risk to accurate transaction processing.
  
  The team performed a full data cleanup, verifying and correcting records to ensure accuracy. This included:
  
  Removing duplicate accounts,
  
  Validating data against actual transaction history,
  
  Updating employee records in coordination with HR.
  
  Data integrity was strengthened, reducing errors and improving efficiency across daily accounting tasks.
- The client faced tight deadlines for importing sales invoices into its accounting system. To meet this challenge, Aider Group implemented data mapping improvements that enabled fast, error-free processing - turning a multi-day workload into a sub-24-hour delivery, in line with internal client standards.
- Throughout the engagement, data security was paramount. Aider Group used secure VPN tunnels and client-provided equipment to safeguard information confidentiality and system access.
  
  To streamline cooperation, dedicated communication channels were established, including:
  
  A dedicated contact inbox,
  
  Weekly progress meetings,
  
  On-demand collaboration via Microsoft Teams.
  
  A clearer workflow and structured task management helped the teams resolve issues quickly and transparently.

What the customer gained:
