Custom internal software · Built, hosted, maintained

The tools you can’t buy off the shelf.

We build the software a small business ends up running on: chasing receivables, reconciling two systems that disagree, tracking commission, moving candidates through hiring. One client at a time, shaped around how the work already happens.

Systems in production for clients in the United States and Australia. We reply within one business day.

What we build

Four problems that keep turning up

In businesses of twenty people or fewer, the same work keeps falling through the gap between the accounting file and everything else.

Receivables and collections

Who owes what, how old it is, who chased them last and what was said. Voids, payment plans and write-offs go through an approval step instead of quietly disappearing.

Reconciliation between systems

Your accounting file against the tool the work actually lives in. Both directions: what is missing from one, what is missing from the other, and which system to fix it in.

Revenue, commission and payouts

Revenue by person and by month, with commission worked out from the underlying figures rather than stored as a number somebody typed. Two sets of books stop disagreeing.

Hiring and onboarding

Applications, screening notes, contracts signed online, and a paperwork trail you can still find a year later.

Running now

Four systems in daily use

Client names are withheld. The work is described as it is.

Mandrex Collections

Supabase · QuickBooks · Xero

A receivables platform holding several client books at once. Hundreds of open invoices under chase, with an approval route behind every void, payment plan and write-off, so nothing leaves the ledger without a second pair of eyes.

Mandrex Job Recon

QuickBooks Online · JobTread

QuickBooks against JobTread for a construction contractor. Customer invoices and contractor bills are pulled read-only every fifteen minutes, and each mismatch comes out as a plain instruction with the system to fix it in.

Revenue and commission tracker

Cloudflare Workers · D1

Revenue by rep and by month for a sales agency, with commission derived at read time and never stored. It surfaced a four-figure gap between two sets of books that neither one had flagged.

Candidate Pool

Cloudflare Workers · Access

Applications, screening and e-signed contracts for an outsourcing team, behind single sign-on, with every signed document kept where the next person can find it.

How it works

Three steps, and the third one never ends

01

Map the work

A call, then a look at the actual spreadsheets and exports. We come back with what we would build, what it would cost, and whether you need us at all. That part is free.

02

Build the first usable version

Weeks, not quarters. You put real data through it early and tell us where it is wrong, which is the only way anyone finds out.

03

Run it

Hosting, nightly backups, security updates, and changes as the business changes. Software is not something you buy once and leave alone.

Standards, not shortcuts.

Your data stays yours

Each client gets their own database. Everything exports. Backups run nightly and are restored on a schedule to prove they are real.

Read-only unless you say otherwise

We read from your accounting file. We do not write to it. Nothing we build can quietly change your books.

One flat monthly

A build fee, then a single monthly amount covering hosting, backups, support and small changes. No per-seat licence that grows with your team.

Let’s talk

Tell us where the spreadsheets are

Describe the part of your operations that runs on exports, reminders and somebody’s memory. We will reply within one business day with what we would build and roughly what it would cost.
