Using data analysis: See how your father's day sales went.
Retail analytics refers to utilising sales, stock, and customer data from your POS to inform better decisions that drive revenue and profit growth. A modern POS system enables these insights to be obtained faster and more easily. When you utilise your POS data effectively, you can identify what sells, where margins are generated, and how customers shop, allowing you to adjust stock, prices, and promotions with confidence.
A quick Father’s Day check in your POS System.
Father’s Day is a good example because it is seasonal, has known gift trends, and gives you a clean way to compare this year with last year in your POS. In 2025, Australians were expected to spend hundreds of millions of dollars on gifts, with fewer shoppers but higher average spending, so category mix and margin mattered significantly. I use its Sales Comparison report to see how the shop performed this week versus last week, and then against the week of Father's Day last year to get a sense of seasonality.
Go to Register reports
Now select Sales register > Sales comparison
Choose dates that match.
Like-for-like dates provide fair comparisons, so start with “last 7 days” versus “previous 7 days” to see how Father’s Day week performed. Next, compare the Father’s Day period this year to the same period last year to remove the effects of weekends and holiday timing that can skew the numbers.
So we want this year's date 1/9/25 to 7/9/25 vs 26/8/24 to 1/9/24
If you want a steadier view, use a four‑week block this year versus the same four‑week block last year to smooth out spikes.
The key numbers to check
Begin with the summary view of the Sales Comparison report, then focus on Quantity, Net Sales, COGS, Gross Profit dollars, and Gross Profit percent to see what drove results. Sort by gross profit dollars to find the categories that did the most work for your margin, then look at gross profit percent to check if discounting cut into your margin. These fields are standard in POS reports and give you a fast read on where to dig deeper if something looks off.
A simple Father’s Day read‑out
Run the Sales Comparison summary for the last 7 days versus the previous 7 days, then scan profit dollars and profit percentage by category to identify areas for further investigation. If one department jumps out, open the detail view for that department to find the SKUs that drove the change and check if discounting or price changes were involved. Re‑run the comparison against last year’s matched period and, if needed, over a four‑week window to confirm if the change is genuine and not just a one‑week spike. Balance your read-out with the known Father’s Day categories in Australia to guide replenishment and any follow-up promotions after the event.
Make sense of what changed.
If profit dollars rose while units fell, the result may stem from higher prices, a better mix, or both. Therefore, examine the items that grew and determine if this trend can be sustained without harming demand. If units rose but gross profit percent fell, promotion depth may be too high, so review discount rules and try bundles or value adds that keep margin healthy. If traffic looked strong but sales were flat, the issue may be conversion or merchandising, so check busy hours and staff coverage in the POS to plan rosters and training.
Avoid common traps
Do not compare random calendar months without adjusting for the number of weekends or the exact timing of Father’s Day, because this can mislead your decisions. Always start with matched weeks or matched four-week blocks, then drill down only when the summary shows a significant swing that requires an explanation.
Make it a habit.
It's an outstanding report, and I suggest that you use it often, as it makes it easy to spot trends early and act. I recommend it for Christmas, back‑to‑school, Mother’s Day, and local events.
Your next step
Open Reports, run the Sales Comparison for the last 7 days versus the previous 7 days. Check profit dollars and profit percentage first, then drill into any category that has moved significantly in either direction. Re‑run against last year’s matched period and, if helpful, as a four‑week comparison to confirm the pattern is real and not a one‑off. Save this setup as a preset, schedule it weekly, and keep using the same columns so your review stays under a minute and your team knows exactly what to act on.
