SAMPLE Largest single finding per project; the five are different kinds of money and are never added together.
Your money lives in six places. Six exports, six versions of the truth.
Each one is right about its own column.
None of them sees the others.
The money falls between them.

One line follows CO-09. Through every record it belongs in.
It is in the log. It is on the billing platform.
It is on no schedule line and on none of pay apps 8, 9 and 10.

Every dollar traced to the cell. A file, a row, a column.
A finding is never a number someone typed. It is a file, a row and a column you can open yourself.

Five kinds of money. Each goes missing its own way.
Each one is a different check against a different record, so they are shown apart and never summed.

Three steps. No integration.
Upload exports
Your change-order log, schedule of values, pay-app lines and A/R register, as CSV or Excel. Read-only: Main never logs into your systems.
Reviewed findings
Tested rules follow every change across every file. A person at Main checks each finding before it reaches you, within 5 business days of complete data.
Get paid
Each finding comes with a drafted next step you approve, and the next import verifies what was billed.
Built for financial data. The kind you cannot afford to leak.
AI interprets
Language models help read and map messy exports and write plain-English summaries. They never compute an amount.
Code calculates
Every amount, date, aging bucket and reconciliation result comes from tested code.
Rules control
Each finding names the rule that produced it and the rows it read. Nothing reaches you without both.
Humans review
A Main reviewer checks every finding before it reaches you. Main does not use customer data to train AI models.
One result. Four controls. Files are scanned for malware before anything reads them and encrypted with a key specific to your organization. How your data is handled

Commercial specialty subcontractors with dedicated finance or project-accounting staff, where project financial truth spans more than one system. About Main
Four questions, answered.
Who can see our data?
Accounts are created only by ordering at /start or by invitation. A paid order at /start creates your organization and its owner account. Everyone else is invited by their organization’s owner or by Main. You sign in with email and password. Every account can also use sign-in codes from an authenticator app, Main staff included. You turn them on in Settings. A remembered device skips the code for a limited time. Sensitive actions ask for your password again. Each organization’s data is kept apart in the app and again in the database. This is tested on every release. Files are encrypted with a key that belongs to your organization alone. Main staff see your data only through a logged workspace session with a stated reason. An activity log records what happens, and entries can only be added, never changed. Main does not claim any security certification. A mutual NDA is available before you send anything.
Do you connect to our systems?
Main works from exports you already produce — from Procore, Sage, QuickBooks, Viewpoint, Excel, Siteline or Clearstory. No integration or new system is needed to start; read-only connections are optional and come later. Main sits above those tools and does not replace them or write back to them.
What are the four exports?
Send the exports you already produce. That means your change-order log, schedule of values and payment applications. Add your A/R aging or invoice register, payments and retainage ledger. Any CSV or Excel file works (.xlsx, no macros). Your column names don’t need to match; you confirm the mapping once. With just a change-order log and pay application lines, Main can already check whether approved changes reached billing. WIP and job-cost data are optional.
What happens if it finds nothing?
If the assessment doesn’t find at least $7,500 of verified recoverable value, the fee is refunded in full. Only approved work that was not billed, or billed short, counts. A person at Main must verify it, and you must be able to bill it now. Over-billing and invoices already sent do not count. Ask within 30 days of the report. The full policy is at /revenue/refund-policy.
