Custom Builds

Spreadsheets built for the job you actually do

Most business spreadsheets started as somebody's quick fix and were never designed. We build the version you'd have made if you'd had the time — and the version your team can't accidentally break.

Locked formulas, validated inputs Plain Excel — nothing new to learn Yours to keep and edit
The Difference

A tool, not a file somebody once made

The spreadsheet you're using probably works — until the person who built it is on leave. Here's what we do differently.

It can't be broken

Input cells are unlocked and validated. Everything else is protected, so nobody overwrites a formula with a typed-in number and quietly corrupts the report.

It explains itself

Named ranges instead of D2:D21, a documented inputs sheet, and notes on the assumptions. The next person can pick it up without a handover call.

It survives next month

Built on Tables so ranges expand on their own. Add rows and every total, PivotTable and chart follows — no re-pointing formulas each period.

Charts and figures worked out by hand on a desk beside a laptop
Every build starts from how you actually work
Also Built

If it lives in a spreadsheet, we've probably built one

A few of the other workbooks clients come to us for.

Quoting & invoicing

Pick the line items, the document builds itself and exports to a branded PDF.

Cash flow forecast

13-week rolling view with scenario toggles, so "what if they pay late" takes a second.

Timesheets & payroll prep

Hours in, costed and coded out — ready to hand to payroll without re-keying.

Sales pipeline

Weighted forecast by stage, with the deals that have gone quiet surfacing themselves.

Capacity planner

Who's booked, who's free, and where next month is already over-sold.

Data reconciliation

Two exports in, a matched/unmatched report out. The month-end job nobody wants.

Compliance registers

Expiring certifications and renewals that raise their hand a month before, not after.

Something else

If you can describe the process, we can usually build it. Ask.

How A Build Runs

From "it's a mess" to handover

1 · Walk through

Show us the current file and how you actually use it. Including the bits you know are wrong.

2 · Spec & quote

We write down what it will do and what it won't, with a fixed price. No surprises.

3 · Build

You see it early and often. Changing your mind at this stage is expected, not billed as extra.

4 · Handover

Walkthrough session, documentation, and the file is yours. No licence, no lock-in.

Want your team to build these themselves?

Everything above is built with the skills taught in Excel Essentials. Some clients train first, then only outsource the hard ones.
