AI Agents and Automation

Reading invoices, sorting requests, copying data from one system to another: the rule-based work that eats your team’s week. I build agents that do it the same way every time and show how they got each answer.

A mechanical arm lifting a paper invoice from a full in-tray toward a laptop, with the finished papers filed in a binder on the other side.
The tray on the left is what someone works through by hand every week. The agent handles the 90th item the same way as the first.

What you get

  • An agent with one clear jobNarrow, testable, and easy to describe in one sentence. Agents with a broad, vague job are where these projects usually go wrong.
  • Work you can checkEvery output links back to the input it came from. No mystery numbers.
  • A person signs off where it mattersAnything involving money, liability or a signature gets drafted by the agent and approved by a person.
  • A test set from your own workReal cases from your business, so any model change gets tested against them before it goes live.

Each value in the record points back to where the agent read it on the invoice, so you can check one against the other. The total is money, so a person approves the record.

Pricing

Fixed prices for the common jobs, and a quote after discovery for anything bigger. Prices in CAD, plus GST.

    Talk about A workflow

  • Run plan · from $3,000 a year The infrastructure it runs on, kept up, backed up and watched. The server it runs on. Storage, and backups you can be restored from. Dependency and security updates. Monitoring, and someone who notices. Cancel at any renewal. You own the software either way.
  • That’s the starting price. A busier or more complex system costs more to run, and we agree on the number in writing along with the build, so it never comes as a surprise.
  • Not included: what you pay other companies. AI model and API keys, third-party licences and app subscriptions stay in your own accounts, at cost. I don’t mark them up.
  • The plan doesn’t include hours for changes. Each change gets its own price, agreed before I build it.
  • I’ll never take a percentage of what you sell: no royalties, no cut of transactions, no per-user fees for software you own.

Priced per agent. I won’t quote a broad, do-everything agent: those are the ones that fail.

When it’s the right choice

  • The task happens often, follows rules a person could write down, and mostly involves reading documents or moving data.
  • It’s done well today, just slowly, so there’s a right answer to measure against.
  • Someone on your team will own it after handover.

When it isn’t

Skip it if an occasional mistake would be expensive and nobody’s going to check the output. Someone on your side has to keep an eye on what it produces.

Not sure it’s this one?

Describe the work in a sentence or two. You’ll see which of the services it reads as, where to start, and what that costs.
