How do I reconcile retainage receivable and payable by job against the latest pay applications with AI?

Retainage sits on the books for months, and by closeout the ledger rarely matches what the pay applications say: a release was booked but never billed, a rate stepped down on one pay app and nobody adjusted the ledger, or a sub's retainage payable doesn't add up to what their own pay apps show held. Have Claude or ChatGPT read the latest pay application to the owner or GC and each sub's latest pay application into one table, and have Copilot in Excel or Gemini in Google Sheets compare those figures with your retainage receivable and payable balances by job. Your controller decides any adjusting entry.

Short answer

Use Claude or ChatGPT, then Copilot in Excel or Gemini in Google Sheets: Claude or ChatGPT reads your latest billed pay apps and each sub's latest pay app into one retainage table; Copilot or Gemini compares it with retainage receivable and payable on the books by job and vendor and flags differences, rate changes and unmatched releases. Retainage sits on the books for months, and by closeout the ledger rarely matches what the pay applications say: a release was booked but never billed, a rate stepped down on one pay app and nobody adjusted the ledger, or a sub's retainage payable doesn't add up to what their own pay apps show held. Have Claude or ChatGPT read the latest pay application to the owner or GC and each sub's latest pay application into one table, and have Copilot in Excel or Gemini in Google Sheets compare those figures with your retainage receivable and payable balances by job. Your controller decides any adjusting entry. A person still checks: every difference against the source pay app and contract before your controller books any adjustment.

Tool: Claude or ChatGPT, then Copilot in Excel or Gemini in Google Sheets

Claude or ChatGPT reads your latest billed pay apps and each sub's latest pay app into one retainage table; Copilot or Gemini compares it with retainage receivable and payable on the books by job and vendor and flags differences, rate changes and unmatched releases.

Prompt 1

Read these pay applications [upload]. Build a table with one row per pay app: job, party, application number, period date, completed and stored to date, retainage rate and retainage held as shown, plus any release amount. Copy amounts exactly and write NOT SHOWN instead of calculating a missing figure.

Prompt 2

Here are the headers and a few sample rows of my Ledger and PayApps tabs [paste]. Write Excel formulas (or a step-by-step Copilot plan) that compare retainage receivable per job and payable per sub with retainage held on the latest pay app, flag differences over [amount], rate changes between pay apps and releases with no matching pay app, and summarize by job. Use only my data and don't propose journal entries.

Human check: Every difference against the source pay app and contract before your controller books any adjustment.

The problem

Reconcile retainage receivable and payable by job against the latest pay applications with AI. This is a common, time-consuming task for a construction accountant.

What this workflow does

Retainage sits on the books for months, and by closeout the ledger rarely matches what the pay applications say: a release was booked but never billed, a rate stepped down on one pay app and nobody adjusted the ledger, or a sub's retainage payable doesn't add up to what their own pay apps show held. Have Claude or ChatGPT read the latest pay application to the owner or GC and each sub's latest pay application into one table, and have Copilot in Excel or Gemini in Google Sheets compare those figures with your retainage receivable and payable balances by job. Your controller decides any adjusting entry.

How it works: AI drafts or analyzes. A person operates the tools, checks the work, and takes action.

Your checkpoint: The reconciliation only compares your ledger with the pay applications you provided. A difference can come from timing, an unapproved pay app or a change order not yet billed, so each flag needs a look at the source documents. Adjusting entries, retainage terms and anything tied to lien or prompt-payment deadlines stay with your controller and the contract documents.

Before you start

  • Access to the named tool; confirm license, version and cost with the vendor.
  • A small, non-confidential sample to try the workflow on first.
  • A qualified person to review the output before it is used.

Tools and access

Follow the steps

  1. Export retainage receivable and retainage payable balances by job (and by vendor for payable) from your accounting system as of month end, and collect the latest approved pay application you billed on each job and the latest approved pay application from each sub.
  2. Have Claude or ChatGPT read every pay application into a PayApps tab: job, party, application number, period date, contract sum to date, completed and stored to date, retainage rate and total retainage held as shown. It copies amounts exactly and writes NOT SHOWN instead of calculating a missing figure.
  3. Have it also list any retainage release billed or received, with the date and amount, from the pay apps and your release invoices.
  4. Have Copilot in Excel or Gemini in Google Sheets compare, per job, receivable on the books with retainage held on your latest pay app, and payable on the books per sub with retainage held on that sub's latest pay app.
  5. Flag differences above a threshold you set, retainage rates that changed between pay apps, releases on the books with no matching pay app or invoice, and jobs that reached completion with retainage still held and no release billed.
  6. Summarize by job for the controller with the likely cause in plain words, and put the release follow-ups in a separate list for the project managers.

Here are the headers and a few sample rows of my Ledger tab [paste: job, account, vendor, balance as of month end] and my PayApps tab [paste: job, party, application number, period date, completed and stored to date, retainage rate, retainage held as shown, release amount]. Write Excel formulas (or a step-by-step Copilot plan) that compare retainage receivable per job with retainage held on my latest pay app, retainage payable per sub with retainage held on that sub's latest pay app, flag differences over [amount], rate changes between pay apps and releases with no matching pay app, and summarize by job.

Expected output

Not published yet. Treat any output as a draft and check it against the source documents.

Check the result

  • Every value, citation or quantity traces back to a source document.
  • Missing information is marked as missing, not filled in.

Limits and recovery

  • The reconciliation only compares your ledger with the pay applications you provided. A difference can come from timing, an unapproved pay app or a change order not yet billed, so each flag needs a look at the source documents. Adjusting entries, retainage terms and anything tied to lien or prompt-payment deadlines stay with your controller and the contract documents.
  • Check your organization’s data policy before sharing project files with third-party tools.

Stop or switch when: The source cannot be verified, permissions are missing, or the result contains unsupported facts.
