1. Two businesses at one counter
The consumables — blades, bits, discs, abrasives, fasteners — are frequent, small, low-value and where the steady money is. The machines are infrequent, expensive, under warranty and where the turnover looks impressive. Both need to work at the same counter: consumables want barcodes and speed, machines want brand, model and serial recorded. Set both up properly at the start rather than treating the small items as an afterthought.
2. Warranty is a real cost if untraceable
A power tool claim is settled on the model, the serial and the date of sale, and the customer arrives with none of them. Recording all three on the invoice means you find it in seconds and pass the claim to the manufacturer rather than replacing it yourself. In this price range a handful of untraceable claims is a month's margin on the category, and it is entirely avoidable.
3. Choosing the brand mix
Tools are brand-sensitive and a working tradesman has strong preferences. Carry one premium brand for the professionals who ask for it by name, one mid-range that will be most of your turnover, and an economy line for price-driven buyers — being clear at the counter which is which. A customer who knowingly chose economy and sees it on the bill does not argue when it wears out.
4. Consumables bring people in
A contractor buys a machine once every few years and blades every week. Those weekly visits are what make you their shop, and they are also when they see whatever else you have added. Never be out of the fast consumables — minimum levels on those thirty or forty lines are worth more to this business than any marketing.
5. Contractor and workshop accounts
Builders, carpenters, electricians and workshops draw tools and consumables through jobs and settle later — frequent small purchases with an occasional large one. Set a credit limit at the start, let the ledger build from the billing so nothing is entered twice, and send a monthly statement. The occasional machine purchase on that account is where the limit gets tested, so set it with that in mind.
6. The number to watch
Margin per item on the fast consumables. This shop earns steadily on blades, bits and discs rather than on the occasional machine, so a rate that slipped on one of those costs more over a year than a poor deal on a power tool. Purchase rate against sale rate finds it, and it is almost always a line nobody was watching.
