The Best CRM for Construction Arbitrage

If you run construction arbitrage, the tool you run it on matters more than most people admit. Some people call this contractor arbitrage or construction dropservicing - same model, different name: you win the work as the main contractor, subcontract it out, and keep the spread (how the model works). The short answer to "what is the best CRM for construction arbitrage" is this: not a generic sales CRM, but a platform built for the way arbitrage actually runs - clients on one side, subcontractors on the other, and your margin sitting in the gap between them. Below is what that means, what to look for, and the honest starter-to-scale path.

Why a normal CRM is the wrong tool#

A standard sales CRM is designed to do one job: move a lead down a pipeline until it becomes a sale, then hand off and stop. That is fine if you sell a product. Arbitrage is not that.

In arbitrage the sale is the start of the work, not the end. Once a client says yes, you still have to:

• Price the job as a finished result to the client.
• Send the same job to one or more subcontractors and get their price back.
• Hold your client price against your sub cost so you can see the spread on every job (how markup works).
• Book the visit, run the job remotely, and get it signed off.
• Invoice the client, pay the sub, and keep the difference.

A generic CRM has no concept of that second side. It does not know a subcontractor exists. So all the pricing, the sub quotes, the markup and the payment tracking end up living in spreadsheets, text messages and your memory - which is exactly where margin quietly leaks out of the business.

The five jobs your tool has to do#

Strip it back and an arbitrage operator's software has to do five things (the lean stack in full):

1. One home for every job, from first lead to paid invoice, so nothing slips.
2. Fast, professional quoting to the client - speed wins work, a 24-hour quote beats a perfect one next week (quoting remotely).
3. A subcontractor side - send the job to trades, get their price, and see it next to your client price.
4. Payments and invoicing you can watch land in real time, so you release the next stage and pay subs on time (cash flow).
5. A written record of every message with clients and subs, useful when memories conveniently differ later.

If a tool does those five well, it fits the model. If it only does one or two, you are duct-taping the rest.

Generic CRM vs purpose-built platform#

Here is the honest comparison, priced in USD (the logic is the same in any currency):

	A spreadsheet	A generic sales CRM	A platform built for arbitrage
Cost to start	Free	~$15-50/user/mo	Low, often per-company not per-seat
Tracks leads and clients	Manually	Yes	Yes
Handles subcontractors	No	No	Yes - the whole point
Shows your spread per job	If you build it	No	Yes, client price vs sub cost
Quoting and invoicing	Bolt-on	Sometimes	Built in
Runs from your phone	Clumsy	Usually	Yes, that is the model
Right for	Job one to three	Pure sales, not arbitrage	Running many jobs as a system

The spreadsheet is a genuine starting point - do not be ashamed of it for your first few jobs. The generic CRM is the trap: it looks like the answer, costs real money, and still ignores the half of the business that makes you money.

What I actually recommend#

Once you are past the first few jobs and running several at once, use a platform built around the operator model. Planajob is one made for exactly this flow: a client raises a job with photos, you quote it as the main contractor, you send it out to your subcontractors, their price comes back, you add your markup and the client sees one clean price - never the sub underneath. Payment runs through the platform, the job carries its own message thread and audit trail, and the whole thing works from your phone. That is arbitrage as a system rather than as a pile of texts and a spreadsheet.

The point is not the specific logo. The point is the shape of the tool: it has to understand that you sit between a client and a sub and earn on the spread. Most software does not. Pick one that does.

The realistic path: start lean, upgrade on volume#

You do not need to buy the biggest tool on day one. The sequence that actually works:

• Jobs 1-3: a disciplined spreadsheet plus your phone. Prove you can win work and price it.
• Jobs 4-15: move to a platform built for the model, so quoting, subs, markup and payment stop living in your head.
• Beyond that: tighten the systems and SOPs around the tool (scaling past yourself) - the software just makes a good process faster, it never replaces one.

Tools do not build a business, systems do. But the right tool is where your system lives, and for arbitrage the right tool is one that was built to sit in the middle - between the client and the sub - because that is where you make your money.

The bottom line#

The best CRM for construction arbitrage is not a CRM in the old sense at all. It is a platform that runs the client, the subcontractor and the spread on one record. Start on a spreadsheet, graduate to something like Planajob that is built for the operator model, and keep your systems sharper than your software. Do that and the tool stops being an expense and starts being the thing that lets one person run many jobs at once.
