How can I tell if a granite countertop shop is profitable before buying?

A granite countertop shop can look busy and still earn little. Stone is costly, the machines are heavy, and one bad job can erase the margin on several good ones. The yearly statements give a total, but they hide which work pays. Before you rely on any profit figure, ask how the shop knows what each kind of job earns, and whether the seller’s records can show it.

Ask for job costing by job type

Kitchens, vanities, bar tops and commercial runs do not cost the same to make. Ask the seller to walk you through a few recent jobs of each type, from the quote to the final invoice, including slab cost, labour hours, consumables and installation. If the shop only tracks revenue, you will have to build the picture yourself, and your accountant can help you read the financial statements alongside the job files. Our countertop fabrication checklist covers the wider review.

Look at slab yield and waste

A slab is paid for whole, but only part of it becomes a countertop. Ask how the shop lays out cuts, what happens to offcuts, and whether leftover pieces are sold or reused for smaller jobs. A shop that plans its layouts well keeps more of each slab. Ask also who is responsible when a slab cracks, and how often that happens.

Count remakes and callbacks as a cost

A remade piece costs stone, machine time and a second trip. Ask how remakes are recorded, whether they are charged to the original job, and what the main causes are: measuring errors, damage in transport or installer mistakes. Ask whether these costs show up in the books.

Check who pays, and when

Builder work and retail homeowner work behave differently. Builders and homeowners may pay on different schedules, and some pay deposits up front. Ask how customers split between the two, how long invoices usually stay open, and whether any single builder accounts for much of the work.

• Does the owner template, fabricate or install, and is that labour on the payroll?
• Would a hired manager cost more than the owner now takes?
• Is the equipment old enough that replacement should be planned for?

The owner’s unpaid labour is the last piece. If the owner does the templating or the selling, add what replacing that person would cost before you call the shop profitable. Equipment condition matters too, so ask for an independent look at the machines before you commit. If you are still searching, see how to find a stone fabrication business.
