Custom quoting + sizing calculators

Turn your quoting rules into working software.

Trim builds custom calculators and quoting systems from the spreadsheets, formulas, edge cases and approval steps your business already uses.

Quote record + customer document

Illustrative workflow: structured request → tested rules → human review → customer-ready result.
Recognize the pattern?

The hard part is already hiding in your process.

This is a strong fit when the quote depends on real business knowledge—not a generic price list—and the same decisions happen often enough to deserve a system.

  • 01

    An Excel or Google Sheets calculator already produces the answer.

  • 02

    One estimator knows the exceptions that are not written down.

  • 03

    Requests arrive incomplete and need repeated clarification.

  • 04

    The result is copied into a quote, report or branded document.

If an existing product already solves this well, I’ll say so. Custom software should earn its place.

What gets built

One operational system, not another disconnected tool.

Final scope depends on the real rules, risks, integrations and approval points uncovered during the Blueprint.

01 · Intake

Collect the inputs that matter

Guide customers or staff through measurements, service choices, files and conditional questions before calculation begins.

02 · Rules

Make the logic explicit and testable

Version the agreed formulas, reference data, assumptions and exceptions instead of relying on a black-box answer.

03 · Review

Keep judgment where it belongs

Route edge cases and material decisions to a human before anything reaches the customer.

04 · Output

Prepare the finished result

Create the internal record, reviewed quote and branded customer document without rebuilding the work by hand.

Relevant delivered pattern

From sizing request to reviewed customer documents.

For a technical-services company, Trim connected structured sizing requests, tested calculation logic, linked quote and approval records, branded documents and a staff review dashboard.

A safer buying path

Scope the uncertainty before paying to build it.

01

Fit call

Walk through the current process and decide whether an existing tool is enough.

02

Workflow Blueprint

Map the rules, risks, prototype, acceptance tests and fixed build recommendation.

03

Fixed-scope build

Build in milestones, demonstrate working software and train the people who use it.

Blueprint range

$1,500–$2,500 CAD

Likely build range

$8,000–$15,000 CAD

Working ranges in Canadian dollars. A written scope and milestone schedule come before any build starts.

Start with the real workflow.

Show me how the work happens.

Send the spreadsheet, formula, repeated decision or handoff that feels harder than it should. I’ll tell you whether it needs a small fix, a blueprint or a custom build.

Replies come from me, usually within one business day.

  • A clear read on whether custom software is justified
  • The safest next step and a realistic price range
  • An honest answer when an existing tool is enough
