Ask three providers what a custom internal tool should cost and you will get three answers that differ so widely they seem to describe different products. One quotes a project fee with a comma in it. One quotes an hourly rate and shrugs at the total. One points you at a platform where you build it yourself.

The confusion is structural: "custom internal tool" covers everything from a form that feeds a sheet to a full back-office system, and every route to getting one prices a different thing. So instead of a single number, here is how the routes actually compare, including our own pricing, in full, as a concrete anchor.

The Four Ways to Buy an Internal Tool

Route 1: build it yourself on a no-code platform. You pay a per-user monthly subscription and supply the labor yourself. The subscription is usually the smallest cost; the real ones are your hours learning and building, per-user pricing that grows with your team, and the ongoing maintenance that lands on you because you built it. We covered this trade-off honestly in DIY platform or done-for-you. For some owners it is genuinely the right route.

Route 2: hire a freelancer for a one-off build. You pay a project fee, own the result, and the meter stops. The structural weakness is what happens after delivery: software needs updating as your business changes, and a one-off engagement has no one on the hook for that. Many of the stuck systems we inherit were healthy freelancer builds whose builder moved on.

Route 3: commission an agency build. The traditional route: discovery, specification, build, handover. Done well it produces excellent software, and for large or unusual systems it is the right call. It is also a significant upfront investment. Custom project quotes vary too much for any honest general number, and the maintenance question from Route 2 applies just the same after handover.

Route 4: subscribe to a built-and-run tool. The newer model, and the one we operate: instead of buying software as a project, you subscribe to it as a running service: the building, hosting, and updating are all inside one flat price.

Our Pricing, as the Anchor

Since this article promises real numbers, here are ours, complete:

Your tool: $99/month. We build it, host it, and update it.
Unlimited users (fair use).
Monthly, cancel anytime. Your data exports free, anytime.
Annual option: $990/year, with 2 months free.
Additional tools are $79/month each.
These prices are locked in for as long as you stay subscribed.

Above the single-tool tier sits our Co-Build offering: a Co-Build Starter at $1,490/month (price locked while you stay subscribed) gives you a team continuously building: one active workstream, a weekly check-in call, and your tools progressively connected into one system where that is the need. It starts with a free working preview of your actual tool, before any payment, and when you subscribe, your payment link arrives in your inbox, usually within the hour. Details on the internal tools page.

We share these not because every business should pick Route 4, but because a public, flat number gives you something honest to compare the other routes against, including their unpriced costs.

What Actually Drives the Cost

Whatever route you choose, the same few things move the price. Knowing them helps you read any quote:

Integrations. A standalone tool is simple. A tool that must talk to your accounting software, calendar, or payment provider is where complexity, and cost, actually lives.
Permissions. "Everyone sees everything" is cheap. "Staff see their own clients, managers see their team, the bookkeeper sees only invoices" is real design work.
Data migration. Moving years of existing spreadsheet history into the new tool cleanly takes real care. Budget for it in any route.
The rate of change. The most underpriced factor. A tool that is finished once is cheap; a tool that evolves with your business needs someone permanently on the hook, which is precisely what subscription models exist to price honestly.

Notice what is not on the list: the number of screens. Interfaces are the cheap part in 2026. Logic, integrations, and upkeep are the product.

Questions to Ask Any Provider

Whoever you talk to, including us, these four questions surface the real cost:

What happens to the price as my team grows?
Who makes changes after launch, and what do they cost?
Who owns my data, and what does exporting it cost? (With us: you own it, and exports are free, anytime.)
If we part ways, what do I walk away with?

A provider with good answers to all four is safe to buy from at any price point. A provider with bad answers is expensive at any price point.

If a flat monthly price with someone permanently on the hook sounds like the right shape for your business, describe the tool you need and you will see it working, free, before you decide anything.
