Four subs on one job means twelve failure points: four schedules that can collide, four invoices that arrive on four different logics, and four separate assumptions about who's responsible when the framing isn't ready for the electrician.
Most contractors I've watched try to solve this with more apps. That's usually the wrong move. The problem isn't that you lack software—it's that coordination between subs is a workflow question, and you can solve most of it with structure before you spend a dollar on tools.
Here's the honest breakdown of the approaches, including where each one falls apart.
The spreadsheet approach: cheaper than you think, until it isn't
A shared spreadsheet with a row per sub, columns for scope, start date, dependency, and payment status will genuinely get you through a small job. Don't let anyone tell you it's amateur hour—for two subs and a two-week timeline, it's the right tool.
Where it breaks: dependencies. A spreadsheet can't tell you that the drywaller can't start until the electrician passes rough-in inspection. You end up holding that logic in your head, and the whole point was to get it out of your head. The second failure is payment. A spreadsheet tracks that you owe someone; it does nothing to protect either side when a sub claims work is done and you disagree.
The all-in-one platform: one login, one blind spot
The pitch for all-in-one is real: scheduling, invoicing, messaging, and payments under one roof means no data re-entry and one source of truth. When it works, it's clean.
The tradeoff is that you're renting someone else's opinion about how your business runs. All-in-one tools optimize for the average contractor, which means your specific sequencing rules, your retainage terms, your inspection gates—the things that actually differentiate a well-run job—get flattened into generic fields. You also concentrate risk: if that one platform has an outage or a billing dispute, every part of your operation stalls at once.

Best-of-breed: powerful, and a maintenance job of its own
Stitching together the best scheduling app, the best invoicing app, and the best messaging app gives you a stack that fits your business exactly. The catch is that you—or someone you pay—now own the integrations between them. Every app update is a chance for the connection to break, and the plumbing becomes a second job nobody scheduled.
The realistic version of best-of-breed isn't five apps. It's a small in-house-tailored core: your own scheduling logic (even in a spreadsheet), your own invoicing rhythm, your own sub communication—and exactly one specialized third-party piece where the risk genuinely warrants an outside party.
Where the one outside piece earns its keep
The single coordination point that shouldn't live in your own stack is money that changes hands on disputed work. That's escrow. When four subs are staged in sequence, the fights aren't about scheduling—they're about whether a milestone was actually hit before the next sub could proceed and before payment released.
Everything else can and probably should be tailored in-house, because you know your sequence better than any vendor. But the payment-on-completion decision benefits from a neutral third party holding the funds against agreed milestones, so 'is it done?' stops being a your-word-against-mine conversation. Keep the coordination yours. Outsource only the part where neutrality is the whole point.
If you want to see how that one piece fits without rebuilding your stack around it, look at how the milestone-and-release structure is set up for multi-sub jobs.
