Executive Summary

In the fast-paced world of Global Capability Centres (GCCs), standard billing often falls short. When your operations involve shifting employee allocations, retroactive salary revisions, and non-linear contractual slabs, "standard" simply isn't enough. That is why we built AmPower ExMan—a sophisticated business logic layer designed to sit atop your ERP, transforming raw data into precise, client-ready invoices with surgical accuracy.

Here is how AmPower ExMan is redefining efficiency for staffing and manpower services:

Key achievements of AmPower ExMan are:

Multiple Billing Entities - in form of Customers and sub-entities like Project, Team and Cost Center within a Customer
Managing Employee States - movement of Employee between Projects, Team and Cost Centers
Complex Billing Contract based on dynamic Rules and Specification, mirroring the worded Contracts
Managing Billing Periods which combines the masters and Billing Contract definitions to create a Billing Data set
Output as Invoices

1. The Digital Timeline: The "Employee State"

Most systems treat employee data as static. AmPower ExMan introduces the Employee State, a time-dependent master that tracks every change in an employee's configuration—from their Team and Project to their Billable CTC—on a digital timeline. This ensures that mid-month transfers or mid-period revisions are never lost, providing 100% historical traceability. Once your employees move between billable entities - Project, Team or Cost Center - the state tracks their movement and the impact on billing impacted because of the movement.

2. Automated "Banded Arrears" Calculation

Retrospective (back-dated) salary increments are a billing nightmare. AmPower ExMan automates this through its Banded Arrears engine. By identifying the CTC Effective Date from revision files, the system automatically compares current versus previous rates and calculates back-dated payments for all intervening months. It handles the cases of change of Team, Project and Cost Center (Billing Entities) and converts the Arrears into a component.

3. Slicing and Dicing: Multi-Dimensional Allocation

Clients often require costs to be "sliced and diced" across various dimensions. Our engine allows for percentage-based or day-based splits across three distinct levels: Project, Team, and Cost Centre. This flexibility means you can generate separate invoices for different project managers or departments from a single pool of employee data.

4. The Advanced Policy Engine

Not all fees are flat. Whether it is seat costs that decrease as your headcount grows (slab-based) or management fees that only apply to specific salary components, our Policy Engine handles the "ifs and buts" of your contracts. It translates complex legal language into automated mathematical rules, ensuring that your billing always aligns with your contractual agreements. It handle cases like banded costing (first 10 at $10 each, then $20 each) or slab based pricing (for example, for employee count as 10, $100/per Employee of surcharge, else $90)

5. An Auditable "Source of Truth"

Data integrity is the bedrock of AmPower ExMan. Before any data hits your general ledger, it resides in a non-modifiable staging area. This acts as a critical checkpoint where Account Managers review and approve "Staging Lines," ensuring that no unverified or erroneous data ever reaches the final invoice.

The Achievement: 60-70% Less Manual Effort

By standardising varied data inputs from systems like Tally or Keka into a unified workflow, AmPower ExMan reduces manual Excel effort by an estimated 60-70%. More importantly, it eliminates the risk of human error in complex calculations, ensuring that your data is always searchable, traceable, and audit-ready.

AmPower ExMan isn't just a billing tool; it’s an automation engine that provides the agility and accuracy today’s GCCs demand.
