TLDR

Purpose: a quick, compliant path to close payroll when exiting a ServiceTrade platform for a tiny NC industrial firm (2–10 employees).
Key steps: export raw pay data (pay runs, hours, allowances) with timestamps; map external IDs to internal payroll IDs; reconcile mismatches; keep a clear audit trail.
Rounding policy: default to symmetric nearest-cent (and nearest-minute where applicable); document exceptions tied to contracts or law; require dual sign-off for overrides.
Documentation: cite contract clauses and NC/federal guidance; file copies with payroll reconciliation; version-control exports.
Exit readiness: use a pre-/post-exit checklist; obtain final sign-off; archive all exports and reconciliations.
Cash impact: typically small; model exposure with a simple example to forecast variance across cycles.
Roles: CFO signs off; payroll lead exports; operations verifies field timestamps; HR flags eligibility/benefits.
Note: timecard edits in ServiceTrade may not reflect job costing—reconcile against dispatch records to avoid errors.

Payroll Rounding Precision under North Carolina Law: A Scholarly Framework for Finance Teams Managing Service‑Platform Exits in Micro Industrial Firms

Précis & scope

Small industrial employers around Research Triangle Park — from Cary back offices to Durham field crews — face concentrated risk when leaving a service platform. Small cent differences can add up. Union contract language can change overtime and benefits. Final pay runs draw audits.

The framework that follows gives a short, stepwise approach. It favors symmetric rounding, clear reconciliation, and minimal disruption. It aims to protect workers and meet contract and statutory duties.

NC legal nuance

North Carolina requires accurate time and pay records. For the official employer guidance, see the N.C. Dept. of Labor (search nclabor.gov for "recordkeeping"). Federal Wage and Hour guidance supports neutral rounding so employers avoid systematic bias and pay for time worked.

When a collective bargaining agreement has hours, overtime, or premium language, rounding and calculation must map to those clauses. Tie the rounding policy to the exact contract section and to state/federal guidance. Keep a copy of the cited contract clause with the payroll file.

Tip: log the contract clause reference (page and article) in the reconciliation worksheet so reviewers can match line items quickly.

Rounding matrix & math

Rounding tiers for payroll calculations and time capture
Tier	Rule	When
1	Nearest cent (symmetric)	Gross‑to‑net calculations; default
2	Nearest minute / 6‑minute interval (symmetric)	Time capture where CBA or policy requires interval rounding
3	Documented fallback (explicit, written)	Overtime lines or unique benefit calculations
4	Manual override with dual sign‑off	Corrections after export or disputed entries
Considerations: choose symmetric rules to avoid bias; keep exception paths documented. Keywords: payroll rounding rules, symmetric rounding, rounding variance, recordkeeping North Carolina.

How much will rounding change payroll cash-flow?

Simple worked example:

Click to expand the worked math

Hourly rate: $30.00

Recorded hours: 40.3333 (40 hours 20 minutes)

Gross (raw): 30.00 × 40.3333 = 1,209.999

Nearest‑cent (symmetric): $1,210.00

Truncation (floor): $1,209.99 → $0.01 difference per paycheck.

Multiply the per‑paycheck variance by the number of affected employees and pay cycles to model sensitivity. Example: 5 employees × 26 pay periods × $0.01 = $1.30 annual difference from that rounding method alone.

Model a conservative sensitivity table in a spreadsheet: vary employee counts, pay cycles, and typical fractional hours to see cumulative exposure. Use symmetric rounding as the default and document any exceptions tied to contract language or law.

Service‑platform exit checklist

Pre‑exit → Post‑exit action map for payroll cutover
Pre‑exit snapshot	Post‑exit adjustments
Export pay runs, hours, allowances, fringe lines	Import verification; reconcile mismatches
Record dispatch IDs and field timestamps	Map dispatch → payroll IDs; resolve late entries
Union dues and CBA flags	Apply final dues timing; obtain sign‑off
Final pay authorizations and sign‑off list	Distribute final pay statements; archive export
Notes: required data fields include employee ID, pay rate, hours with timestamps, allowance codes, tax treatment, fringe credits, and sign‑offs. Keep raw exports and reconciliation worksheets for audit.

Core responsibilities (simple roles):

Payroll lead — export and primary check
Operations lead — field reconciliation and timestamp verification
HR — eligibility and benefit flags
CFO — final sign‑off and legal check

Be aware: timecard edits in ServiceTrade don’t always reflect job costing properly. Plan a reconciliation that compares the exported timestamps to dispatch records.

Expanded checklist steps (export, map, reconcile, sign)

Run full export with raw timestamps and all payroll lines.
Hash or checksum the export for version control.
Map external IDs (dispatch) to internal payroll IDs.
Run row‑level reconciliation; flag mismatches and route for dual sign‑off.
Document all overrides with reason and dual signers.
Run a mock final pay run in parallel to confirm totals before live cutover.

Audit & retention

Keep a clear audit trail: raw exports, reconciliation worksheets, and sign‑off logs. Version control every export. Retain records consistent with state guidance. For the specific retention period, reference the N.C. Dept. of Labor guidance at nclabor.gov.

Run simple decision analytics dashboards to find anomalies: repeated late entries, missing allowance lines, or unexpected rounding patterns. Quantify rounding variance monthly and include the metric in payroll close notes.

Rounding: Use symmetric nearest‑cent as the default. Document any exception and the legal basis.
Platform exit: Data migration, reconciliation, and controlled payroll cutover with dual sign‑off.
Audit trail: Time‑stamped exports, versioned policies, and sign‑offs stored for review and defense.

Practical audit tips:

Keep the raw export as the source of truth. Never overwrite the original file.
Save a readable reconciliation with row‑level notes for each exception.
Log the person, date/time, and reason for each manual override.
