Turn your Excel workflow into a web app your whole team can trust

We migrate the spreadsheet that runs your business into software—with the same logic, cleaner permissions, and none of the version chaos.

Your Excel file is not the problem. The problem is that it became the database, the approval system, and the customer record—with no audit trail and no way for more than one person to work safely at once.

Diagnose My Workflow

What breaks today

The pain we hear on almost every intake

Email attachments named FINAL_v4

Nobody knows which file is current. Reconciliation meetings eat hours every week.

Formulas only one person dare touch

Add a column and three dependent sheets break. Vacation becomes a business risk.

No mobile access for people in the field

Crews call the office for status because the sheet lives on one desktop.

What we build

Focused deliverables—not a vague retainer

Web app that mirrors your familiar fields

Same columns and statuses where it helps—without the fragility of linked workbooks.

Role-based access and change history

See who changed what, when—and stop accidental overwrites.

Exports and integrations when you still need them

Pull from QuickBooks, push to email or Slack, export to CSV for finance when required.

How we work

One workflow, one milestone, expand from proof

01

Document the sheet that actually runs things

Not every tab—just the workflow that breaks or blocks growth.

02

Build the smallest web version that replaces daily use

One role, one path, one happy team before adding edge cases.

03

Retire the spreadsheet deliberately

Parallel run, validation against the old file, then cut over when numbers match.

Proof

Home services contractor client story

Before
Job schedule, crew assignments, and customer notes lived in a shared Excel file on a office PC. Field supervisors texted updates that often never made it back.
What we built
A mobile-friendly job board synced to the same data model—crews see today’s jobs, office sees status changes in real time.
After
Dispatch stops playing phone tag. Invoicing pulls completed job data without re-keying from the sheet.

Investment

What this costs

What does it cost to turn Excel into a web app?

Single-workflow conversions with one integration often start between $2k–$20k. Larger ops platforms with multiple roles and migrations typically phase between $20k–$60k.

If three people spend five hours a week fixing sheet versions and re-entering data, a $15k build pays back in roughly a year at modest loaded labor rates—faster if errors were hitting billing.

We scope around the one workflow that hurts most. You are not committing to a full platform rewrite on day one.

Questions

Straight answers

The logic moves into software where it is testable and owned. We validate outputs against your current sheet before cutover.

Yes. That is usually why teams make this move—concurrent access without merge conflicts.

A focused single-workflow app often ships in 4–10 weeks depending on integrations and data cleanup.

We can export structured data on a schedule. Many teams keep Excel for analysis but stop using it as the system of record.

Sheets plus automation works until permissions, volume, or mobile access break down. We help you choose honestly.
