Sales tax rules vary by state and locality and may differ for firearms, ammunition, accessories, range fees, and gunsmithing services. Your POS should apply the correct tax rate to each transaction category automatically and generate a tax summary report that your accountant can use for filing. Manual tax calculation across hundreds of daily transactions is error-prone and creates reconciliation headaches.

Inventory aging reports show how long each serialized firearm and product SKU has been in stock. Any firearm sitting for more than 90-120 days is tying up cash and costing you carrying costs. Use this data to make markdown decisions, run targeted promotions, or negotiate return-to-vendor arrangements with your distributors before slow-moving inventory becomes a cash flow problem.

Profitability analysis requires tracking cost of goods sold (COGS) against actual selling prices — not just revenue. A gun shop POS with margin reporting shows you gross profit by product category, brand, and individual SKU. You may find that handguns drive volume but accessories drive margin, or that a particular ammo brand sells quickly but at razor-thin margins. This data drives smarter buying and pricing decisions.

Key shooting range performance metrics include lane utilization rate by hour and day, revenue per lane hour, membership count and retention rate, class attendance and revenue, and rental gun revenue per unit. Hourly utilization data is particularly valuable for staffing decisions — you can reduce RSO labor costs during slow periods and ensure full coverage during peak hours.

Shrinkage tracking requires logging every inventory adjustment with a reason code (damaged, theft, vendor return, administrative error) and attributing it to an employee. For firearms, every discrepancy between physical inventory and A&D records must be investigated and resolved — it’s not just a financial issue, it’s a compliance issue. Regular cycle counts and receiving audits catch shrinkage early before it accumulates.

Period-over-period sales trend reports show seasonal patterns in your specific store — when 9mm spikes, when shotgun ammo sells, when handgun purchases peak. Layering this data against your current inventory levels and distributor lead times allows you to place smarter orders and avoid both stockouts and overbuying. Intuition alone isn’t reliable enough for inventory planning in a margin-sensitive business like gun retail.

The most important regular reports for gun shop owners are: daily sales by category (firearms, accessories, ammo, range, service), gross margin by product line, inventory aging (to spot slow-moving stock), layaway aging (to identify at-risk deposits), and compliance status (open A&D entries, unlinked 4473s). Weekly and monthly trend comparisons help you spot problems early and make informed buying decisions.
