About this tool
Surface mismatches between your billable hours and the invoice line items.
The Invoice-to-Time-Log Reconciler multiplies each time-log row's hours by its rate, sums the result per activity, and compares that expected amount against the invoiced amount for the same activity, marking a line Match when the variance falls within your tolerance and Review when it does not. Paste time-log rows as 'Activity | hours | rate' and invoice lines as 'Activity | amount', set a tolerance (default ±1), and you get a per-activity variance table plus a match count such as 2/3. It is for freelancers, agencies and clients who need to know exactly which line drifted, not just that the invoice total looks wrong.

Paste one row per line into Time-log rows in the hinted Activity | hours | rate format, for example Research | 5.5 | 1500.
Paste the bill into Invoice lines as Activity | amount, then set Amount tolerance, which defaults to 1, or press the 'Three lines' example chip.
The Result reads '2/3 lines match' over a table of Activity, Expected from log, Invoiced, Variance and Status; Copy puts it on the clipboard and Download saves invoice-to-time-log-reconciler.txt.
Groups repeated rows by activity name and shows expected, invoiced and the signed difference for each, so a 500 overcharge on one line is not cancelled by an undercharge on another.
Any line whose absolute variance is within your tolerance is marked Match, which lets rounding pass while real discrepancies still show as Review.
Activities present in only one of the two lists still appear, with the missing side counted as zero, so an invoiced item that was never logged is impossible to miss.
One row per line as 'Activity | hours | rate', for example 'Research | 5.5 | 1500'. Invoice lines use two fields, 'Activity | amount', such as 'Research | 8250'. Activity names must match between the two lists for a line to be paired.
Variance = invoiced amount − (hours × rate), computed per activity after summing duplicate rows. A positive variance means the invoice charged more than the log supports; a negative one means hours were logged but under-billed.
It sets the absolute variance, in currency units, that still counts as a match — the default is ±1. Raise it to something like 50 when the invoice was rounded to whole units, and set it to 0 when you want an exact reconciliation.
Yes — the rate lives on each time-log row, so research at 1500 and design at 1800 are each expanded at their own rate before being compared to the matching invoice line. Rows sharing an activity name are added together first.
