What AI workflow automation costs
Three lines make up the bill: the build, the upkeep and the tool licences. A simple two-system workflow from a small studio is typically a low four-figure job, while a group of connected processes with AI steps reaches five figures. Enterprise platforms start higher. Figures on this page are orientation ranges for comparing proposals, since most providers quote per project.
Cost per workflow
Agencies price a workflow by its complexity, not by the hours a person currently spends on the task. Complexity comes from the count of systems, the branches in the logic, the state of the data and how much error handling the process deserves.
| Workflow type | Example | Indicative build price | What pushes it up |
|---|---|---|---|
| Simple sync | Web form creates a CRM contact and a chat notification | €500 to €2,500 | Field mapping quirks, duplicate handling |
| Multi-step process | Inbound email is classified, a ticket is opened, the customer record is updated | €2,500 to €10,000 | Branching rules, approvals, retries and alerts |
| Document workflow with AI extraction | Supplier invoices are read, validated against orders and posted to the ERP | €8,000 to €30,000 | Document variety, validation rules, ERP access |
| Cross-department programme | Quote-to-cash across CRM, ERP, billing and support | €30,000 and up | Number of teams, data migration, governance |
Retainers and ongoing support
Workflows break when a connected app changes its API, when a field is renamed or when volumes grow. Someone has to watch for failures and fix them. Providers package this in three ways.
- Support retainer. A monthly fee for monitoring, fixes and a set number of change hours. Suits companies with a handful of important workflows.
- Automation subscription. A fixed monthly capacity, used for both new builds and maintenance. XRay.Tech and RevPartners sell variants of this model.
- Hourly on demand. No commitment, billed as used. Cheapest when changes are rare, slowest when something urgent fails.
- Handover. The agency documents the flows and trains an internal owner. The recurring cost becomes staff time.
Tool licences: how each platform counts usage
Licence cost depends less on the headline plan price than on what the platform counts. The same process can be cheap on one tool and expensive on another purely because of the metering unit. Check current prices on the vendor pages, as plans change often.
| Platform | Unit it bills | Effect on cost | Pricing page |
|---|---|---|---|
| Zapier | Tasks: each successful action step | Long flows at high volume add up quickly | zapier.com/pricing |
| Make | Credits: each module run | Cheaper per step, but loops and polling consume credits | make.com/en/pricing |
| n8n | Executions: one full workflow run | Step count does not change the bill; self-hosting moves cost to your own server | n8n.io/pricing |
| Workato | Quoted by the vendor | Enterprise contracts, so budget for a sales cycle | workato.com/pricing |
What AI steps add
Each classification, extraction or drafting step calls a language model and is billed by the model provider per token, on top of the automation platform's own fee. For short emails and single-page documents the amount per item is small. It grows with long documents, large volumes and the choice of a bigger model.
The larger AI cost is usually design and testing: writing prompts, assembling sample documents, checking accuracy and building the review screen for cases the model is unsure about. Ask each bidder how many samples it will test against and what accuracy it expects before go-live.
Ways to lower the total
- Fix the process on paper first. Automating a messy sequence makes the mess faster and the build dearer.
- Estimate monthly runs and steps per run before choosing a platform, then compare licence cost on that basis.
- Use a small model for classification and reserve larger models for drafting.
- Group related workflows into one project so shared connections and error handling are built once.
- Ask for documentation and credentials in your own accounts, which keeps a later change of supplier cheap.
Common questions
Is self-hosted n8n free?
The software licence for the community edition carries no fee, but you pay for a server, backups, updates and the time of whoever maintains it. Some features are reserved for paid plans. Read n8n's licence terms and pricing page before planning a commercial deployment.
Should licences sit in our account or the agency's?
In yours. Workflows, credentials and logs that live in your own workspace remain available if the relationship ends. Give the agency access as a collaborator instead.
