Retainage release · fixed fee

Your retainage is
not a dispute.It is a paperwork backlog.

Five to ten percent of your contract is held until the job closes out, and it is usually the whole profit. We finish the closeout paperwork standing in front of it and work the release in your name, for a fixed fee.

What the wait costs
0 days

Average wait for a subcontractor to receive withheld retainage. The GC above them waits 99 days.

5% to 10%

Of your contract value, held back until the job closes out. Usually the entire profit on the job.

0 days

Substantial completion to final check, across a study of 39 commercial projects.

Closeout paperwork on a desk: a payment application, manufacturer warranties, a rolled set of as-built drawings and a stack of lien waivers.
The paperwork standing between one finished job and one check.
01What the money is waiting on

The bottleneck is almost never a dispute.

It is as-builts, O&M manuals, warranties, waivers from every lower tier vendor, consent of surety, and a final pay application that references all of it.

Getting those documents takes six to ten weeks of asking six different parties, at the moment your crew has already moved to the next job.

Internal closeout rarely fails on competence. It fails because follow-up number four never happens.

Your GC's portal is a mailbox. It tells you the package is incomplete and never tells you what to do about it.

Released, specimen

$0

Released is the only word we celebrate, and it is the day the money cleared, not the day we submitted.

We never promise a GC will pay. We promise the paperwork will not be the reason they do not.

03How we work it

Four steps, and three of them are ours.

01

You send one subcontract

We read it and write a Release Map, free: what is held, what your contract requires to release it, what is missing, who has it, and the deadlines.

02

We get the missing pieces

Every request goes out in your name, on a dated cadence, to your GC, your suppliers, your broker and your bonding agent.

03

We assemble the package

One indexed PDF in the order your GC asked for it, with a final pay application that references every item in it.

04

We work the release

Weekly follow-up with the GC's project manager and their accounting desk. A person approves every message before it leaves.

04What it costs

A fixed fee, named by the fact that sets it.

One payment per claim. No subscription, no percentage of what is released, nothing assigned, no card stored.

Per claim

The subcontract value sets the price, so there is nothing to choose. A $1,500 fee against $84,000 held is the whole argument.

Guarantee

If your GC rejects the package as incomplete, we fix it and resubmit at no charge. If it is still incomplete after that, the fee for that claim is refunded.

Nothing to cancel. You add the next job when it closes out.

One action

Send one subcontract. We read it and write the map.

Nothing on this page collects your details. Email one subcontract PDF and we read it by hand and send the Release Map back, free, on one job.
