The workflow covers a task your team already does. Z4C provides documentation and handover.

Each workflow has an activity log and an agreed acceptance test. A $1,000 monthly care plan covers maintenance, small changes and running the AI, within reason.

Why a fixed-scope workflow?

One administrative task, one approved integration and an agreed acceptance test keep the scope clear before you pay.

Can we change what it does?

The written scope states what the workflow does and its limits. Larger changes need a new written scope.

What data can it use?

You approve the data and software it can use before work starts.

How is the price set?

The workflow is $15,000, one time, with fixed scope. The call produces a written scope with the work, access, delivery date and acceptance test. You do not pay until you approve it. A $1,000 monthly care plan keeps it running after handover.

What happens on the call?

The call takes 20 minutes. You describe one repeated task. If Z4C can do it, you get a written scope before any payment.

Stop running your company blindfolded.

One workflow handles the follow-up work that slows you down. Your team approves every message before it sends. $15,000 to build, $1,000 monthly to run.

WHAT WE BUILD

Three example workflows. You choose one.

Candidate availability and status

Track candidate availability, draft status updates and interview-confirmation reminders once a recruiter approves the stage.

Example A candidate replies with two open windows. The coordinator sees both and approves the message before it goes out.

Client-submittal follow-up

Draft follow-ups on submitted candidates and flag missing updates between recruiters and account managers. A person approves each message.

Example A submittal has no client reply for a set period. The account manager gets a flagged draft to approve.

Onboarding checklist reminders

Remind candidates about the agreed onboarding checklist and flag missing items for a person. It makes no compliance or hiring decisions.

Example A missing form triggers one reminder draft. The recruiter decides whether to send it.

Examples show what is possible. They are not results from past clients.

Illustrative example with synthetic data: see the candidate-availability review demo. No ATS, inbox or calendar is connected, and nothing is sent.

WHERE IT PAYS OFF

If your team does it every week, it may be worth a call.

Every draft, reminder and handoff is recorded in an activity log.

Your team stays in control

Your team approves every message and system change before it happens.

Common questions

Is this only for staffing and recruiting?: No. The three examples here come from staffing and recruiting. The same workflow fits any company with a repeated follow-up. Describe the task on the call. We will say plainly whether it fits.
What if I am not sure what to automate?: That is what the free call is for. Describe a normal week and we point at the repeated tasks worth discussing. If you do something more than ten times a week, it is often worth a look.
What does it cost?: The workflow is a $15,000 one-time, fixed-scope engagement. Scope, integration access and the delivery date are agreed in a written plan before you commit. You pay nothing until you approve that plan. After handover, a $1,000 monthly care plan covers maintenance, running the AI and small changes, within reason.
What can the AI see and do?: Only what you approve. The plan lists the data it reads, the systems it can use, and which actions wait for a person. Candidate scoring, ranking and hiring decisions are excluded.
