What coordinating subcontractors is actually costing your trades business

Every job a trades business runs that uses subcontractors generates a stack of coordination work that never quite makes it into the quote. Getting the right people on site at the right time means checking availability, sending job details, waiting for confirmation, chasing the ones who haven't replied, re-confirming the week before, and starting the whole cycle again whenever someone drops out. None of it is hard. All of it takes time — and for a business running five or ten jobs at once, it adds up faster than anyone tracks.

The job that falls between the cracks

When you price a job, you cost materials and your own labour. You might factor in the electrician, the plumber, or the plasterer. What doesn't make it into the quote is the hour or two a week spent keeping each of them confirmed, informed, and showing up.

The pattern is the same on every job. A subcontractor gets a message asking if they're free. They reply — or they don't, and someone has to follow up. Once they're confirmed, they need the job address, access details, what's needed, and when. A week later, a reminder. If something shifts on site — materials delayed, another trade running late — they need to know. If they cancel the morning of, someone has to find a replacement fast.

Multiply that across three or four subcontractors per job, and five or ten jobs running at different stages, and you have a communications load that runs in the background all week. It never surfaces as a clear block of work. It shows up as a string of messages you're sending from the van, a call you're making while you're trying to do something else, or the vague feeling that you're always chasing someone.

What the hours actually look like

A message to confirm availability: a few minutes. Chasing when there's no reply: a few more. Sending job details once someone's confirmed: a few more. A reminder a day or two before the start: another few minutes. A last-minute scramble when someone drops out: potentially an hour.

For a smaller operation running two or three jobs a month with one or two subcontractors each, this is manageable. For a busier operation — five or more concurrent jobs, several trades involved on each — the overhead is consistent and real. It is also invisible: it never shows up as its own line on the week, so the cost rarely gets acknowledged until the owner stops answering their phone or someone starts falling through the cracks.

What automating this looks like

The repetitive end of subcontractor coordination follows a predictable pattern: confirm, brief, remind, re-confirm. That is the part that an automation handles well. Once a job is logged with the trades it needs and the start date, the system sends the availability check, tracks who has replied, follows up with those who haven't, sends briefing details when someone is confirmed, and fires a reminder before the job starts.

If a subcontractor cancels or goes quiet too close to the start date, it flags immediately — rather than surfacing when the van is already on the way to site. The owner or site manager gets the alert with the full picture: who dropped out, what the job needs, and when.

What stays with the person is anything that requires judgement: choosing which subcontractors to call on for a given job, handling disputes, deciding who to work with again. The automation handles the coordination around decisions that have already been made.

What it doesn't do

This works for the routine flow around confirmed jobs. It is not built for negotiating rates, handling a subcontractor who has gone quiet over a payment dispute, or anything that needs a direct conversation rather than a message. It also depends on jobs being logged consistently — if the system doesn't know who is needed and when, it cannot coordinate anything.

It is also worth being honest that a system like this takes a few weeks to bed in. The value is not in any single reminder sent; it is in the cumulative hours you stop spending on follow-up over months.
