Excel Expert Needed to Clean and Improve Estimating & Manufacturing Workbook

Remote Full-time
I have an existing Excel workbook that:

Takes measurements as inputs

Calculates required materials based on those measurements

Generates a cutsheet for fabrication (exact lengths to cut)

Builds a materials list for ordering

Calculates job costs and selling price

Produces a customer-facing agreement and invoice

The workbook functions but needs to be cleaned up, centralized, and made more user-friendly.

Scope of Work

1. Clean & Protect

Separate input cells from outputs (color/shade inputs, lock formulas).

Add data validation (dropdowns, error checks).

Protect formulas so they cannot be overwritten.

Set print areas so reports export cleanly.

2. Centralize Rules

Move all “growth” or adjustment rules (e.g., +1" to track, −½" deduction, rounding for rods, etc.) into a single Rules Table.

Ensure Cutsheet and Materials List reference this table so adjustments are simple.

3. Materials & Ordering

Ensure the materials list accurately rolls up linear feet and counts by component.

Add editable waste factors (e.g., 5% extra for extrusion, 10% for rods).

Create a clean summary sheet for ordering (e.g., “Order X LF component A, Y LF component B, Z hardware items”).

4. Pricing & Costing

Centralize all costs, labor rates, tax, and markups into a Pricebook sheet.

Update pricing formulas so everything pulls from Pricebook.

Ensure totals flow correctly to cost summary, sales agreement, and invoice sheets.

5. Documentation & Reliability

Add an “Admin Guide” inside the workbook (how to update costs, rules, waste factors).

Clean up or remove broken named ranges.

Deliver a protected master template ready for daily use.

Deliverables

Updated workbook with:

Centralized Rules Table

Centralized Pricebook

Locked and protected formulas

Clean input/output separation

Polished reports (Cutsheet, Materials List, Pricing, Agreement, Invoice)

Short admin guide (1–2 pages) explaining how to update rules and costs

Requirements

Advanced Excel (formulas, named ranges, data validation, protection, clean structure).

Experience building manufacturing calculators, fabrication cut lists, or construction estimating tools.

Strong ability to document changes and explain logic clearly.
