What a principal employer should ask a vendor compliance audit to check
A vendor audit should explain what was checked, which workers and periods were covered, and what evidence is still missing. Document collection is only the starting point.
Planning the engagement
Define the population and review period
List the contractors, establishments and periods included in the assignment. Record whether the exercise is a remote document review, an on-site review or a combination. Agree whether records will be checked in full or through a documented sample, and identify any activities excluded from the scope.
Obtain the contractor master and site-wise worker deployment information before reviewing totals. A contractor may supply more than one client or location, so a company-wide challan or payroll summary does not by itself identify the people deployed at the principal employer’s site.
Planning the engagement
Connect attendance, wages and payment evidence
The agreed checks can compare deployed worker information, attendance or muster records, wage calculations and payment evidence. Where relevant, the review should identify the wage category, period, overtime and deductions being assessed. Use current applicable references rather than an undated checklist.
Report inconsistencies at the level supported by the records. Distinguish a mismatch from a document not supplied, and identify what explanation or additional evidence is required. Record sampling limitations so management understands the boundary of the finding.
Planning the engagement
Reconcile social-security evidence
Where applicable and within scope, connect worker identifiers and wage records with employee-level EPF/ESIC evidence and the relevant contribution/payment records. A payment receipt supports one part of the review; the employee population and contribution basis still need to be understood.
Where records do not align, request clarification through the nominated client or contractor coordinator. Avoid treating the presence of a challan as proof that all workers and wages for the site have been correctly covered. Preserve the documents and period on which the reported finding is based.
Planning the engagement
Review the remaining applicable records
The assignment may include establishment and contractor registration or licence particulars, statutory registers, wage-related records and other requirements applicable to the activity. The list should be tailored to the workplace and workforce, rather than assuming every vendor requires the same documents.
Identify responsibility for maintaining each record and handling renewals or amendments where relevant. Any inspection support, historical correction or legal representation should be separately described when it is not part of the agreed audit. A document review should not imply that an unvisited site was physically inspected.
Planning the engagement
Make closure visible to management
Use an exception register showing the contractor, location, period, evidence reviewed, finding, action owner and follow-up status. Agree the escalation route and what evidence is needed to close each finding. Record unresolved items separately from those that have been corrected and rechecked.
Repeat findings can indicate a process problem in contractor onboarding or evidence collection. Review those patterns with procurement, HR and the site team, within the agreed scope. The useful outcome is a documented basis for management action—not an unsupported promise of complete or permanent compliance.
