Detecting discrepancies before they become incidents - payslip by payslip, month after month.
An ADP payroll typically contains several thousand active pay codes, configurations inherited over many years, and a volume of payslips that no payroll administrator can exhaustively check by hand. Discrepancies always exist - the question is not whether they exist, but when you discover them: before the DSN filing, after an employee complaint, or during an URSSAF inspection.
GBA Connect uses ACE, ADP's payroll control tool, to transform this control process into a systematic, traceable, and industrialised workflow.
Who this offer is for
- You are an ADP payroll user (Decidium, GlobalView, ADP Link, GAP) and your payslip volume exceeds the manual control capacity of your teams
- You have just completed a payroll migration or a major configuration change and want to secure the first payroll runs
- Your current controls rely on manual Excel extractions that are not replayable or traceable
- You hold payroll compliance responsibility (CFO, HR Director, Payroll Manager) and need auditable proof of control
What we deliver
- Mapping of your payroll risk areas: sensitive populations, high-stakes pay codes, high error-rate management events
- Design and configuration of ACE controls: business rules, tolerance thresholds, month-on-month and period-on-period controls
- Monthly production of control reports: discrepancies detected, root cause analysis, prioritisation of corrections
- Remediation process management: transmission to payroll administrators, correction tracking, clearance verification
- Management reporting for HR Directors/CFOs: discrepancy rate, recurring error typology, improvement indicators month after month
- Auditable documentation and audit trail in the event of an URSSAF inspection, statutory audit, or employee dispute
Client testimonials
"Previously, we discovered discrepancies through employee feedback or N+1 retroactive adjustments. With the tooled control process in place, we detect them at the pre-payroll stage and correct them before the payslip is issued. DSN filings go through without rejection, and employee queries have dropped significantly."
- Payroll Manager, services group, 4,500 monthly payslips - assignment carried out by the founding partners before GBA Connect was established
Success indicators
- Payslip control rate brought to 100% (vs. sample-based control)
- Discrepancy detection lead time reduced to D-2 before payroll close (vs. post-payslip detection)
- Reduction in retroactive adjustments month on month through identification of recurring root causes
- Evidence file structured and ready to mobilise in the event of an external inspection
Format & duration
Two possible modalities depending on your maturity level:
- Implementation + handover: an 8 to 12 week project to map, configure, and train your teams - you then operate independently.
- Delegated monthly run: GBA Connect produces the ACE controls and associated reporting each month. Annual commitment, volume billed according to number of payslips and configuration complexity.
What we do not do
GBA Connect does not handle payroll production itself: we control, we do not input. This separation is deliberate - it guarantees the independence of the control process from production.
