The Problem

Sound familiar?

Most Nigerian fabricators are leaving money on the table — or losing jobs because their quotes have no structure.

😓

You guess the price and lose

Estimating "by feeling" means you quote too low, win the job, then lose money when diesel, steel prices and labour costs eat your margin.

📉

Overhead is invisible

Generator costs, rent, machine maintenance — they rarely appear in quotes but silently consume every naira of profit. You work for nothing.

Quoting takes too long

Calculating every line item in Excel or on paper is slow. By the time your quote is ready, the client has moved on to a competitor.

Testimonials

What Nigerian workshops say

★★★★★

"Before this tool I was guessing my quotes. I won a structural steel job last month using it and made 28% profit — the best margin I've had in two years."

AO
Adewale O.
Steel Fabricator, Ibadan
★★★★★

"The generator overhead calculation alone is worth everything. I never properly accounted for diesel costs before — I was losing money on every long job."

KA
Kunle A.
Machine Shop Owner, Lagos
★★★★★

"I used to quote brake and alignment jobs off the top of my head. Now I add the parts, the labour hours, and it gives me a proper written quote in minutes."

BO
Bashir O.
Auto Mechanic, Oshogbo
★★★★★

"My customers now get a real printed quote instead of a verbal price — for engine work, diagnostics, even tyre changes. It makes my workshop look serious."

CE
Chidi E.
Auto Repair Workshop, Lagos

⚡ Diesel ₦2,475/L · Grid ₦100–230/kWh. Generator cost is a major overhead in SW Nigeria.
📅 Job Scheduling
🏢 Fixed Monthly Costs (shared across concurrent jobs above)
🛠️ Equipment value is recovered over an assumed 10-year working life, spread across the days this job takes — same logic as rent, just for the machines themselves rather than the building.
⚡ Power & Fuel
⛽ Generator fuel cost is now calculated directly from this job's actual machine + labour hours (fuel use/hr × hours), not a fixed daily assumption — it scales precisely with how long the job really takes.
