Enterprise Excel Consulting & Modernization

Cloud Connectivity • Custom Workbooks • Excel Add-ins • Web Interfaces • User Authentication

Achieve governance and connectivity without ugly migration roadmaps.

We are ex- Big Four and Supermajor consultants with decades of experience building and maintaining enterprise software solutions involving Microsoft Excel from Excel add-ins to model auditing and clarity tools.

How we work

  1. Discovery (1–2 weeks) — Stakeholder interviews, current-state review, success criteria.
  2. Design (1–2 weeks) — Architecture, governance controls, integration plan, validation approach.
  3. Pilot (2–4 weeks) — Prototype the hardest paths end-to-end to de-risk delivery.
  4. Rollout (4–8 weeks) — Iterative delivery with training, documentation, and change management.
  5. Support (ongoing) — Enhancements, telemetry, SLAs.

A real game-changer. Now, our Geochemists can do actual interpretation. They didn’t earn PhDs to copy-paste all day.

And it’s a relief that changes are easy to build and validate.

Sales Performance Management

Centralized data.

Authentication icon

User authentication.

Previously, sales performance data was tracked Excel workbooks. Version control, aggregate insights, and real-time data were difficult to attain.

Department leads continue to use familiar Excel workbooks, but now they're synced with a cloud database—solving the shortcomings of the previous approach, and increasing security.

Automated Geochemistry Reports

92%

Reduction in effort.

0%

Rework.

Previously, PhD geochemists would manually execute SQL queries to find available test results and interpret which graphs (traces) to generate before compiling the report.

Now, they enter one or more Sample IDs and receive completed reports. Hyper-automation handles the queries, inventory interpretation, trace generation, and report preparation.

Detailed Estimating Tool

Win rate increased.

Strategy icon

More time for strategy.

Maintaining their estimating schedule on larger projects became risky and error-prone. Win rate for bids declined.

Now, every estimate starts from the same template and scope management is automated, ensuring no worksheet, column, or cell is forgotten or miscalculated. Database sync grants real-time visibility.

Automated Engineering Proposals

Speed icon

6x faster proposals.

Quality icon

Output quality guaranteed.

Previously, new proposals were made by editing old proposals. New team members frequently broke the Excel model.

Now, sales engineers enter specs into a web form and receive a completed proposal in seconds. Admin users can manage templates and branding assets in a content governance library.

The Excel model is automated and runs in the background with no human interaction. Only admins can access it directly.

Frequently Asked Questions

Massive talent pool and rapid iteration. With the right controls, Excel scales securely.

We add governance, authentication, and connectivity so teams keep the flexibility they love, while IT gets the control it needs.

Discovery — Design — Pilot — Rollout — Support.

We de-risk early via a focused pilot. See How we work for details.

Role-based access, auditability, and data separation are first-class.

We centralize data (not in-workbook), enforce auth, and align with your policies for logging, retention, and change control.

Pilots in 2–4 weeks; phased rollouts in 4–8 weeks.

Typical projects range from ~$5k for automation utilities to $200k+ for multi-team platforms (median ~$35k).

Yes—from side-panel UIs to automation services.

See our add-ins: Sheet Sherpa and Flow Finder.

Yes. We commonly integrate with Salesforce, QBO, Monday.com, DocuSign, and internal databases.

Our goal is seamless sync so Excel is a governed front-end—not a data silo.
