A build, end to end
We ran our own business through our own process.
Indenture is the invoicing software Cruxsmith runs on: a native Mac app that turned a monthly chore into a handful of clicks. We built it exactly the way we build for clients, so instead of telling you how an engagement goes, we can show you, screen by screen.
The crux
An hour the business wanted back, every month
Every month, the books asked for the same ritual: check the next invoice number by hand, assemble a PDF, write the email, chase the payment, log it all somewhere a tax preparer could live with. None of it was hard. All of it was constant, and constant is what quietly eats a business.
Your crux will be different. Missed calls, intake forms retyped into three systems, scheduling, inventory counts, quotes that take an evening. The specifics never match. The shape always does: a piece of work that repeats forever and deserves to be software.
The process
Exactly what an engagement looks like
This is the same path every client walks. We just happened to be the client this time.
Name the crux
A plain conversation about where the hours actually go. For us: invoicing and the bookkeeping around it. For you, it's the free fit call.
Prove it fast
A working core in days, not a deck: draft an invoice, number it correctly, render a clean PDF. Real software you can click, exactly like a Crux Roadmap.
Build in milestones
Each piece reviewed before the next: audit-safe numbering that can't double-issue, client templates, reports. You sign off at every step.
Hand it over
It runs on one Mac with zero subscriptions and zero per-seat fees, and the owner holds the source code. That's the handover standard.
The software
Single clicks where a chore used to be
Shown with demonstration data. Every screen below replaced something that used to be done by hand.
The dashboard answers the three questions that used to take a spreadsheet: what recurs every month, what's been collected, and what needs attention today. Recurring invoices generate themselves and queue up for review; issuing the batch is one click.
The ledger holds every invoice with its status: paid, open, overdue. Numbering is sequential and audit-safe by construction; an issued invoice can't be quietly edited, and a voided one keeps its number, which is exactly what a tax preparer wants to see.
Open one and the editor sits beside a live render of the finished document. Pick the client and the line items fill themselves from that client's templates; issuing is one click: numbered, locked, exported, ready to send.
The year at a glance, by status and by client. Year-end close and contractor paperwork stopped being a January project and became a button.
The second wave
Local clicks first. Then the clicks remove themselves.
Wave one is local: everything above runs on one Mac, private by default, no subscriptions, no per-seat fees. Single clicks where chores used to be.
Wave two reaches out. Some enhancements need remote access, so they're added only when they earn their place: invoices that email themselves from a built-in outbox, and payment links that send themselves through a small cloud service wired to Stripe, so "chase the payment" becomes "watch it arrive." That second wave is already built for Indenture, switched on as volume justifies it.
That's the point of building this way: the software is never finished, it's enhanced. Whenever the next click is worth removing, we remove it, and the work keeps trending toward zero.
The honest part
Yours will look nothing like this
Your business doesn't need an invoicing app, and nothing about your software should look like ours. What transfers is the process: name the crux, prove it fast, build it in signed-off milestones, hand over something you own outright, and then keep shaving clicks off it for as long as it serves you. Indenture is simply that process, photographed.
