The Building-Materials Depot Playbook
Open and run a building-materials depot in Nigeria the honest way — cement, rebar, roofing, tiles and the lot. Anti-hype: cement is where the traffic is, not the money, and a depot is not passive income.

What you'll gain
A building-materials depot looks like the simplest business in the world — buy cement, sell cement — and that simplicity is exactly what ruins people. Built from a source-graded 2026 research pass over the cement dealership model, the SON standards regime, the real storage science and the honest economics, this course teaches the version that survives. First, the truth that reframes the whole trade: cement is where the TRAFFIC is, not the money — the razor ~₦500-a-bag margin (about 4.5%) belongs mostly to the factory (Dangote’s margin runs near 59%), and your profit lives in the fast-moving consumables and the finishing lines (tiles, plumbing, paint) at 30–45%. You will learn where a depot sits in the trade and why you buy from a sub-distributor, not the factory; the cement-dealership model (and why the “huge deposit” story is a myth — it is CAC + a bank reference + verified facilities + a one-trailer cash-and-carry, and any “appointment fee” is a scam); and the compliance stack — including the fact that “I only sold it, I didn’t make it” is NO defence: under the SON Act the seller of substandard cement, under-gauge rebar or fake cable faces a fine of at least a million naira and jail. You will learn the cement-storage chapter that protects your capital (cement cakes two ways and has a ~3-month shelf life — store it off the ground, off the wall, no more than ten bags high, oldest first), the daily open + in − out = close discipline that beats theft, and the money, honestly: a MODELLED depot clears about ₦2.16m a month at ₦30m revenue on a blended ~7.3% margin, breaking even around ₦14m. Then the killer — not low sales but CREDIT: one ₦2m bad debt wipes out the profit on four thousand bags, and the courts will not help you recover it. Two owners, Chidi and Halima, build alongside you. Carry one line: buy right, ration credit, and let finishing goods — not cement — pay you.
