Know how they pay before you sign.

Subs, GCs, developers and suppliers rate each other on real projects. Payment records come from invoices and remittances, not opinions.

“We moved to a 15th-of-month check run in August and expect to be inside terms from here.”

Most of what you need to know shows up after you sign.

You learn how a GC pays once your crew is mobilized.By then the material is bought and the schedule is set.
The low bidder walked off a job last year.Under a different LLC, so nothing comes up when you search the name.
Credit terms get set on references the customer picked.Nobody hands a supplier the name of the vendor they paid 90 days late.

Subs and GCs don't even agree on how late payment is.

Every rating starts with a real project.

No project on file, no rating.

Verify the relationship
A contract, PO, pay app or invoice shows the two companies worked together. A moderator checks it.
Both sides rate, sealed
Each company rates the other. Neither sees the other's review until both are in or 14 days pass. Same rule for good reviews and bad ones.
Log the payments
Invoice due date and the date the money arrived. The other side confirms it or disputes it.
Reply, don't delete
A company can answer publicly or send facts to a moderator. Nobody can erase the other side's review.

Try the math.

Days late = date paid minus the contractual due date, never below zero. Some payments are set aside instead of counted.

Result

55 days late

Paid 55 days after the due date. This counts toward the payment index.

Effect on the sample GC

Aldervane's payment index: 76 becomes 72

Demo scoring. The real weights get set with pilot companies.

Who rates what depends on who paid whom.

Payment and performance are separate scores. A good builder can be a slow payer, and the profile shows both.

Suppliers work the same way. A supplier rates its customer on payment, order clarity and delivery access. The customer rates the supplier's delivery times, order accuracy, product quality and billing.

Fair question: don't these tools already exist?

Some of them cover part of it. Here's what each kind is built for, and what it leaves out.

Tool	How it works	What it can't tell you
Lien and payment toolsLevelset (Procore)	Lien notices and waivers. Its public payment profiles used to rate GCs and owners as fast or slow payers.	Profile reviews were anonymous and one-way. Levelset has since stopped hosting contractor reviews and hid the payment score. Levelset FAQ (archived)
Business credit reportsD&B, Experian	Suppliers report how a buyer pays its bills.	Only suppliers that choose to report are counted. Experian says about 10,000 of the 500,000+ suppliers that extend credit report to it. Nothing on how a company runs a job. Experian FAQ
Prequalification platformsISNetworld, Highwire, TradeTapp	The hiring company vets a contractor's safety, insurance and financials.	It runs one way. The sub doesn't rate the GC or owner back, so you see nothing about how the GC or owner pays.
Homeowner reviews and BBBAngi, BuildZoom, BBB	Property owners review contractors. BBB's grade leans on complaint history.	Company-to-company work: how a GC treats its subs, how a sub performs for a GC, how a builder pays its suppliers.
ContractorRef	Every company on a project rates the companies it worked with, and logs payment dates.	Credit history, insurance, safety programs. Use it alongside those tools, not instead of them.

Only verified projects.

No contract, PO, pay app or invoice on file, no review. Every rating is tied to a project both companies actually worked on.

A new LLC isn't automatically a clean slate.

We check Colorado Secretary of State records for shared registered agents and addresses. A moderator reviews each possible match, and the company can respond before anything is linked.

Both sides, same job.

The sub rates the GC and the GC rates the sub on the same project. Neither side sees the other's review until both are in or 14 days pass.

Rules that make it hard to use as a weapon.

A rating site is only worth checking if the companies on it think it's fair. These rules apply to everyone.

Payment records

A disputed invoice is set aside while a moderator checks the documented reason. The number of disputes shows on the profile.
Retainage isn't late until it's due for release. Approved extensions and disputed change orders don't count as late.
Fewer than 3 records shows “Insufficient data”, not a low score.
Invoice amounts and contract terms aren't shown publicly.

Reviews

Reviews describe companies, not individual employees.
Sealing and publishing follow the same rule for every review, good or bad.
Any company can respond publicly or take a review to a moderator. The review stays up while it's checked.
If a moderator is connected to a company, someone else handles its records.

What each side gets out of it.

General contractors and CMs: See a sub's schedule, safety and closeout record from other GCs before you award. And if you pay on time, there's finally a record of it.
Subcontractors: See how a GC or developer pays before you bid: days past terms, how change orders get handled, whether the site is ready when they say it is.
Material suppliers: Check payment history from other suppliers and trades before you open an account or raise a credit limit.
Developers and homebuilders: Screen GCs and trades on finished projects, and see how your own pay practices look from the other side.

We're starting with about 30 Colorado companies.

Denver metro first: GCs and developers, trades, and suppliers. Free during the pilot.

What we ask

A few finished projects you can document, and honest feedback on the rules.

What you get

Your profile set up before public launch, free access during the pilot, and a say in how scores and disputes work.

Nothing is published outside the pilot group until the dispute process has been tested.

Questions we hear first.

Something else? Ask in the form above and we'll answer it directly.

Are the reviews anonymous?

No. Every review shows which company wrote it. Supporting documents like pay apps and lien waivers are seen only by moderators.

Will a GC stop hiring us if we rate them?

It's a fair worry, since reviews aren't anonymous. Both sides rate at the same time and neither sees the other's review until both are in, so it isn't one sub calling out a GC on its own. And payment records come from documents, not opinions.

Can a company take down a bad review?

No. It can respond publicly, and it can send facts to a moderator if something is wrong. The review stays up while it's checked, and corrections are logged.

We held a payment for a reason. Will that count against us?

Mark the invoice as disputed and attach the reason. A moderator checks it, and it doesn't count toward the payment score while it's open. The number of disputes shows on your profile.

Who sees our invoices?

Other members see each invoice's due date, paid date and days late. Not amounts or contract terms. Moderators and the two companies involved see the documents.

How do you catch someone who closes one LLC and opens another?

Colorado doesn't list LLC owners publicly, so we compare what the Secretary of State does publish: registered agent, principal office and mailing address. Plenty of unrelated companies share a commercial registered agent, so a match is only a signal. A moderator reviews every one, and the company can respond before anything is linked.

What does it cost?

Nothing. It's free during the pilot.

Why only Colorado?

A network is only useful when your real partners are on it, and payment rules differ by state. Colorado, for example, caps retainage at 5% on most private projects where the prime contract is $150,000 or more, and on the subcontracts under them (HB21-1167). We'd rather get one market right first.
