Estimators and bid leads
The Proposal Says One Total, the Estimate Says Another: A Pre-Submit Bid Packet Reconciliation
When proposal and estimate totals disagree, don’t average them. A contractor/estimator reconciliation checklist for Windows bid folders—before you submit.
Both totals look reasonable on their own. Which number is actually going into the proposal?
A bid packet can hold a proposal cover, an estimate workbook, alternates, addenda, and revised scopes. Each file can be “right” in isolation. The miss happens when people check files separately instead of reconciling the numbers—and the assumptions behind them—together.
If you assemble or review bids from a Windows folder under deadline pressure, this is a pre-submit gate you can run without new software. The goal is simple: no unexplained variance ships.
Name the authoritative question before comparing numbers
Before you open anything, write down what “the total” means for this bid:
- Base bid only?
- Total with selected alternates?
- Tax-inclusive or tax-exclusive?
- Client-facing contract value vs internal cost-plus markup?
At the top of your reconciliation sheet, also record:
- Bid due date
- Bid package / revision ID
- Pricing basis (lump sum, unit price, allowances included/excluded)
Do not split the difference. Do not pick the lower number to “be competitive” without an owner’s decision. Averaging in your head is how wrong numbers become official.
Build a two-source total check
Create one row for the proposal and one for the estimate (add more rows if you have alternates or option packages):
| Source | Total as shown | Currency / tax / allowances / alternates | Filename + revision/date | Page, sheet, or cell | Variance | Status |
|---|---|---|---|---|---|---|
| Proposal | — | — | — | — | — | matched / explained / unresolved |
| Estimate | — | — | — | — | — | matched / explained / unresolved |
Rules:
- Record the numbers exactly as shown—do not “fix” rounding in the sheet.
- Capture the location of each number so a second person can re-open the same cell or page.
- Every non-zero variance gets a status. Unresolved means stop—do not submit.
Work through the common causes of mismatch
When the covers disagree, walk the usual suspects before you rewrite either file:
- An addendum changed quantities, scope, labor assumptions, or required alternates—and only one document absorbed it.
- Tax, contingency, freight, or allowances appear in one total and not the other.
- A revised estimate never updated the proposal cover (classic under deadline).
- Formula, unit conversion, rounding, or an excluded line differs between workbook and narrative.
- Two jobs, phases, bid options, or schedule periods got combined in one place and not the other.
Write the cause next to the variance. “Looks off” is not a cause.
Reconcile line items, not just the cover totals
Cover agreement is necessary; it is not sufficient. Work top-down:
- Scope and quantities
- Labor and material rates / assemblies
- Allowances and exclusions
- Alternates and additions
- Markups, tax, and contingency (only if they belong on the client-facing number)
Tie every unexplained dollar to a line, assumption, or written instruction (addendum, email, meeting note). If the proposal intentionally differs from the estimate—strategic price, rounded presentation, owner-directed alternate—record why and who approved the difference. Intentional variance without an owner is still a risk.
Check addenda and revised sheets
Keep a simple addenda log in the bid folder (spreadsheet or plain text is fine):
| # | Date | Filename | Incorporated in estimate? | Incorporated in proposal? | Reviewer initials |
|---|---|---|---|---|---|
| — | — | — | — | — | — |
Confirm both the estimate and the proposal reflect the latest applicable addendum. Keep superseded files available for audit, but clearly mark which packet is being submitted—e.g. a SUBMIT/ subfolder or a SUBMITTED_[timestamp] copy so nobody edits the live set after the fact.
Use a final submit gate
Before the packet leaves:
- A second person reads the final total from the actual outgoing proposal—not from memory, not from the estimate alone.
- Open the estimate source and verify the assumptions behind any remaining difference.
- Save a submission copy with bid revision and timestamp.
- List unresolved questions before sending. If something is still unresolved, escalate—do not hope the client will not notice.
This gate is slower than “send it.” It is faster than explaining a wrong number after award—or after you win a job you cannot perform at that price.
One possible Windows workflow (optional)
Folder tools cannot replace takeoff, markup, or full construction management. Some are designed to help people notice when related documents disagree inside authorized Windows folders.
Sclerite is a Windows 10/11 desktop app in that category: authorize the bid folder (not the whole PC); Watch is a designed path for surfacing a proposal-versus-estimate disagreement; Ask can help locate relevant source wording or numbers. You should still open both original files and reconcile them manually. That is designed behavior—not a promise that every mismatch will be found. First value is designed around authorizing folders and building an index. Sclerite is not a takeoff, markup, estimating, or CM replacement, and it does not silently rewrite source documents.
