Every figure on this page is computed from the inputs entered, by the method stated below it. Binstockly publishes no catalogue, no interchange table, no fitment data and no target margin: the usage, the lead times, the costs and the prices are yours, and the defaults are a worked example to replace with your own figures.
The inventory half of auto parts software is six fields and four figures, and that is genuinely most of it. The six fields are the part number, the bin it lives in, what it cost, what it lists at, how many are on hand and when it last sold. From those six, a system that is doing its job produces four figures: inventory accuracy from a count, a reorder point from usage and lead time, the margin after the discount the counter actually gives, and inventory turns from cost of goods sold against average stock value. Everything else a vendor demonstrates is built on top of those, and a system that holds the six fields but cannot produce the four figures is a list rather than an inventory. This guide walks each field and what it feeds, so a shortlist can be judged on whether the arithmetic comes out rather than on how the screens look. The four figures are worked free by the sheets on this site.

The six fields
Part number and bin locate it, cost and list price price it, on-hand counts it and last sold date ages it. Drop the last sold date and the dead stock question becomes unanswerable, which is why it is the field most often missing from a spreadsheet.
The four figures
Accuracy (matched lines over lines counted), the reorder point (usage times lead plus cover, over seven), margin (profit over the price actually charged) and turns (cost of goods sold over average inventory). Each is arithmetic on fields you already keep.
What to ask a vendor to show you
Not a feature list: ask for those four figures produced from a sample of your own data during the demo. On the worked example that is 87% accuracy, a reorder point of 21 units, a 40% margin and four turns a year, and any system worth buying can show its version of all four.
Auto parts software inventory: common questions
Is a spreadsheet enough?
For the arithmetic, often yes, and the sheets on this site are proof: they are the arithmetic and they are free. What a spreadsheet does badly is being the record when more than one person is touching it, and keeping the history of what a part cost and sold for over time.
What about interchange numbers?
They are a seventh field and they come from a licensed data supplier, not from your own records. Binstockly has no interchange data. If matching a competitor's part number is your daily problem, that is a catalogue purchase and we will say so.
Which figure should I fix first?
Accuracy, because the other three are computed from stock levels. A reorder point calculated from an on-hand figure that is 13% wrong by line will order the wrong quantities with great confidence.
