Power meter billing in Sharper calculates usage as the difference between the current reading and the previous reading. This works correctly under normal conditions, but edge cases — especially meter rollovers — require manual intervention. Both the Marina and Campground module offers Meter Readings as a feature but Meter data is not shared across modules.
Meter Rollovers
A rollover occurs when a meter's numeric display resets to zero after reaching its maximum value (for example, a meter that reads up to 99999 rolls back to 00000). When this happens, Sharper calculates a negative usage value (current reading minus a larger previous reading), which produces an incorrect bill.
How to Handle a Rollover
Navigate to Marina → Meter Readings or Campground → Meter Readings.
Find the reading that triggered the incorrect calculation — it will show as a very large or negative usage value.
Option A — Edit the reading: Correct the current reading to reflect the true usage by accounting for the rollover. For example, if the meter rolled at 99999 and the new reading is 250, the true usage is (99999 - previous reading) + 250.
Option B — Void the invoice and enter manually: If an invoice has already been generated from the incorrect reading, void it, correct the meter reading, and generate a manual invoice for the correct amount.
Preventing Future Issues
If a meter is known to roll over frequently, consider:
Resetting the meter and noting the reset date in for your meter records.
Adding an internal note to the space record documenting the rollover history.
Meter Audits
To audit meter assignments and verify billing accuracy:
Navigate to Reports → Marina or Reports → Campground.
Run a Meter Reads report for the period you want to audit.
Compare reported readings against actual meter records.
Look for:
Readings that jump significantly (possible data entry errors)
Spaces with no readings for a billing period (missed reads)
Readings that do not match the physical meter (transcription errors)
Meter Read Report
The Meter Rent Roll report shows all meters with their associated spaces, current readings, and billing status. This is useful for a complete audit of all utility billing across the property.
Navigate to Reports → Marina or Reports → Campground.
Select the Meter Reads report type.
Run the report for the period you want to review.
Export to Excel for detailed analysis.
Accounting Implications of Meter Corrections
If a meter reading correction results in a voided invoice:
The voided invoice removes the revenue entry from the general ledger.
