Size and shape

How many businesses there are and how small they are. Fragmentation is the first thing an entrant — or anyone selling software into this industry — needs to know, and it is one of the few things that is actually measured.

Largest four provinces by establishment count. Establishments with employees only — sole operators with no payroll are not in this table, so in trades and personal services the true number of businesses is higher.

Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.

How businesses here compete

The structural profile of subsector 332, which every industry beneath it inherits. This is analyst judgment from how the subsector is organised — not research into this industry, and not a measurement.

regional competitionmedium capitalUNVERIFIEDinherited from 332 Fabricated metal product manufacturing

The classic machine and fabrication shop: reachable by acquisition from a retiring owner, limited by machine hours and skilled labour, and exposed to a few large customers.

Who sets the price: The customer's drawing and a competitive quote.
The software it runs on: Job-shop ERP, quoting, scheduling, CAD/CAM.

Operating businessScreened

Certified Tank & Pressure Vessel ShopOne thing must be true

binding constraint: growth quality

The reachable proposition here is not a can line — that is a continuous-process plant selling to a handful of beverage fillers — but a code-stamped tank and pressure-vessel shop: propane and fuel tanks, heat exchangers, process vessels, welded to a registered design for regional energy, agricultural and industrial buyers. It is a real small-business population (303 Canadian establishments, a third of them under ten people) and the welding-code registration that looks like a barrier can be bought with an existing shop. The cut is what the one listed Canadian owner of such shops reports. TerraVest Industries grew sales 50% to $1,371.2M in fiscal 2025 — and its base portfolio grew 1% ($725.6M against $717.4M) [A]. Every other point of growth was purchased: four tank and vessel makers acquired in the year. That is the shape of the industry stated by its best operator: demand for tanks is flat replacement demand, and returns come from buying shops, consolidating steel purchasing and spreading certified designs across plants. An independent entrant owns one shop in a flat market, buys plate at a worse price than the consolidator, and meets that consolidator again as the natural bidder when it wants to sell. The 19% adjusted EBITDA margin TerraVest earns is a portfolio result, not a single-shop one. Software sold to these shops is screened separately.

binding constraint: distribution

Incumbent ECI Software Solutions (JobBOSS²) and Epicor

There are tens of thousands of machine and fabrication shops and no channel that reaches them — they are not on LinkedIn, they buy at trade shows and from their machine-tool distributor, and the ACV does not fund a field sales force. ECI and Epicor got there through decades of distributor relationships rather than through product. Nothing is disclosed here. Every vendor named on this record is private, or sits inside a parent that does not break the line out, so no revenue floor can be built and the market size is genuinely unknown rather than estimated.
