What the checker catches

Run this scenario in DocketMath using the Wage Backpay calculator.

Before you run DocketMath’s Wage Backpay calculator in North Carolina (US-NC), your spreadsheet should pass a short set of jurisdiction-aware checks. DocketMath can compute backpay math quickly—but if your inputs are misaligned (wrong date columns, missing hours, inconsistent pay rates, or worksheet totals that don’t reconcile), the output will be wrong just as fast.

This “spreadsheet checker” focuses on data-quality guardrails that commonly break wage backpay calculations. It does not attempt to determine liability, entitlement, or whether any claim is legally provable; it helps you confirm the math inputs are coherent.

The most frequent spreadsheet problems it catches

Date issues
- Missing or non-date entries in your “start” and “end” columns.
- Mixed date formats that can be interpreted inconsistently (for example, 1/2/24 meaning different things depending on regional settings).
- Pay periods that don’t align with your wage detail rows (e.g., work dates that don’t match the pay period grouping logic your spreadsheet uses).
Duration and hours logic
- Negative or zero hours for work days (often caused by a formula sign error, swapped fields, or unintended filtering).
- Hours exceeding reasonable thresholds per shift (this is a flag for review, not an automatic rejection).
- Rows that have hours but no corresponding pay-rate fields (leading to defaulting or blanks during calculation).
Pay-rate consistency
- Incomplete pay-rate columns (blank hourly rate, missing salary-to-hourly conversion assumptions, or absent effective-date mapping).
- Multiple pay rates applied to the same period due to an incorrect lookup key.
- Rounding drift (for example, converting cents to dollars too early, then converting again later).
Overlapping or gaps in wage entries
- Overlapping time ranges between rows (a common way to double-count the same work).
- Gaps where your worksheet indicates employment continued, but no wage entries exist (the checker surfaces this mismatch so you can confirm whether it’s a real absence or a missing data import).
Worksheet alignment errors
- “Summary” and “detail” tabs that don’t reconcile (totals don’t match).
- Currency/units mismatch (for example: hours recorded in minutes, pay recorded in cents, or totals already multiplied when the calculator expects base values).

Note: Spreadsheet checks are not a substitute for legal analysis. They help ensure your backpay math runs on clean, consistent inputs. If you’re unsure which rules apply to a specific situation, consider getting help from a qualified professional.

North Carolina: applying the time window (general SOL period)

For the timing window, this workflow uses a general default 3-year period as the applicable SOL starting point. Be very clear about what this means:

This is general/default guidance for the checker workflow.
No claim-type-specific sub-rule was found here, so you should treat the 3-year general/default period as the baseline unless you have a statute-based reason to apply something else.

North Carolina also references the SAFE Child Act in the state’s victim support materials. For this checker workflow, that reference is included for jurisdiction context, not because there is a claim-type-specific time rule implemented in this checker.

Quick “pass/fail” indicators the checker returns

Check	Pass looks like	Fail looks like
Date parsing	All dates parse cleanly	`#VALUE!`, blank dates, or mixed formats
Hours fields	Hours are numeric and ≥ 0	Negative/zero where work is expected
Rate fields	Hourly/salary inputs are present for each row	Missing rate values or blank pay assumptions
Period coverage	Rows cover the intended timeframe without overlaps	Overlaps or gaps that don’t reconcile
Reconciliation	Detail totals match summary totals	Summary totals diverge materially

When to run it

Run the checker before you click “calculate” in DocketMath’s Wage Backpay tool—ideally as soon as your spreadsheet reaches a stable structure.

Run the checker before importing a spreadsheet into the Wage Backpay workflow. It is especially helpful when you have multiple entries or when a teammate provided the inputs.

Best timing in your workflow

After you import or copy data into the worksheet tabs.
Before you apply filters or adjust time ranges.
Immediately after you add new pay rows (additional pay periods).
After any formula changes that affect totals (hourly rate conversions, rounding settings, or lookup tables).

Practical triggers that mean “run it now”

You changed column headers or renamed fields.
You switched between manual entries and spreadsheet formulas.
You added a second pay-rate column or began using effective-date logic.
Your summary total stopped matching the sum of detail rows.

Warning: Running the calculator on a spreadsheet with overlapping pay periods can overstate backpay by counting the same work twice. The checker is designed to surface that risk before you rely on the number.

Jurisdiction-window reminder (general default)

Because this guide uses a general/default 3-year SOL period for the North Carolina timing window, make sure your worksheet date ranges are consistent with your intended analysis window. If you’re working outside that baseline (for example, because another statutory rule applies), capture that clearly in your workflow so you don’t accidentally rely on the default window.

Try the checker

Use DocketMath as your worksheet validation layer, then feed the cleaned inputs into the Wage Backpay calculator.

Upload the spreadsheet, review the warnings, and then run the calculation once the inputs are clean: Try the checker.

When rules change, rerun the calculation with updated inputs and store the revision in the matter record.

1) Open DocketMath Wage Backpay

Start here:

/tools/wage-backpay

2) Identify which inputs drive the checker

Your spreadsheet should provide, at minimum, consistent wage detail data. Common columns include:

Work start date (per pay row)
Work end date (per pay row)
Hours worked (numeric)
Pay rate (hourly or salary-to-hourly method)
Any adjustment/bonus fields you plan to include
Optional notes fields for traceability (useful when reconciling totals)

3) Watch output changes as you fix inputs

A practical workflow is iterative:

Run the checker with current data → note which checks fail.
Fix the underlying issue (dates, missing rates, overlaps, reconciliation).
Run again → confirm the checker clears those items.
Only then run Wage Backpay math → compare updated totals.

To make fixes measurable, keep a short changelog, such as:

✅ Converted date format to ISO (YYYY-MM-DD)
✅ Filled missing hourly rates for the last 2 pay periods
✅ Removed overlap where two rows covered the same week

4) Treat reconciliation mismatch as a blocking issue

If the checker reports summary ≠ detail totals, treat it as a blocking problem. Even when the calculator runs, reconciliation problems often indicate:

A filter applied to one tab but not another
A formula referencing the wrong range
A unit mismatch (minutes vs hours, cents vs dollars)

5) Use North Carolina default time-window logic deliberately

When DocketMath applies the general 3-year default SOL period, the tool will effectively limit which wage entries fall within the baseline time window based on your date columns. Clean date fields matter even more here: a single misparsed date can move an entry in or out of the window and change the final number.
