Northline Distribution Center · specimen figures.
Average wait for a subcontractor to receive withheld retainage. The GC above them waits 99 days.
Of your contract value can remain withheld until the job closes out, on work you have already finished.
Substantial completion to final check, across a study of 39 commercial projects.
Many closeout delays are not disputes.
They are missing paperwork and unanswered requests. 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 6 to 10 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
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.
Four steps, and three of them are ours.
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.
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.
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.
We work the release
Weekly follow-up with the GC's project manager and their accounting desk. Every message is checked against your Release Map and your authorization before it leaves, and lands dated on your claim page.
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.
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 person's company, and my name is on it.
I am Mohammad, and Flow is mine. I am not a construction veteran. I built Flow around one observation: closeout is repetitive, document-heavy, and sitting directly on top of your final payment.
So I built it to carry that load, and I set the rule it works under. Nothing goes out in your name unchecked against your own subcontract and your signed authorization. Every message we send sits on your claim page, dated, in the words we used.
I answer for all of it. Write to hello@flow.nanocorp.app and it reaches me. Ask for a call and it is me on the line, not a sales desk.
Mohammad — Founder, Flow
What that means in practice
- Every message we send in your name is written onto your claim page, dated, before you have to ask for it.
- We never write to anyone whose address you did not give us, and we never ask for a document your own subcontract does not name.
- One email stops any thread. The authorization you sign says so, and it is withdrawable in writing at any time.
Nothing on this page is a testimonial. There is no customer quote here because there is not yet a customer to quote.
One action
Send one subcontract. We read it and write the map.
Drop one subcontract PDF and watch us read it back to you, free, on one job. No account and no password, and we ask for your email after the map, not before.
