“Build one n8n automation” is not enough information for a useful quote. One trigger and one output can be a small delivery. Three input formats, OAuth, retries, and an operator dashboard are a different product. I price the boundary before I price the hours.
What the $799 contract sprint fixes in advance
The current Builderlog 72-hour reliability sprint deliberately stays inside this boundary:
| Item | Included scope |
|---|---|
| Business task | One operational process |
| Workflow boundary | Up to three connected n8n workflows |
| Input | One versioned, allowlisted contract |
| Replay state | Data Table for low concurrency or an atomic database boundary when events can race |
| Review | Fail closed when trusted decision evidence is missing |
| Validation | At least five anonymous acceptance and fault cases |
| Evidence | Versioned decision, replay, and recovery receipts |
| Documentation | Import, failure-injection, recovery, and operating runbook |
| Revision | One in-scope revision |
| Delivery | 72 hours after scope and samples are confirmed |
Once the job crosses that line, it is not a slightly larger version of the same package. Multiple integrations, several input formats, or a full operations interface need their own scope.
Define one input, one output, and one failure condition before asking for a price.
Five things that increase automation cost
1. The number of input formats
A single form submission is different from accepting email, spreadsheet rows, and webhooks at the same time. Every input needs its own field mapping, missing-value rules, and duplicate definition.
2. External service connections
Reading one public API is not the same as writing into a service that requires OAuth approval. This package does not collect passwords or log into buyer accounts. The buyer connects credentials inside their own n8n environment.
3. Failure handling
A happy-path demo is fast. A working business flow needs explicit behavior for timeouts, malformed input, duplicate execution, concurrent events, and partial success. Without persisted replay state and a visible recovery path, the automation creates a new manual checking job.
4. AI output validation
When classification or generation is involved, “the API returned 200” is not a success condition. Empty output, forbidden terms, length limits, and malformed structure need gates before the result moves downstream.
5. Operations after delivery
An importable file plus a guide is different from server setup, remote account access, and ongoing monitoring. Builderlog delivers the former. Remote installation and managed operations are excluded.
The six-line brief that produces a useful scope
No legal name or company identity is required. Describe:
- The steps a person performs today
- Weekly frequency and minutes per run
- The input format and three anonymous examples
- The desired output and one success example
- The duplicates, omissions, or errors that must be blocked
- Your n8n environment and the names of external services
Do not send passwords, API keys, customer lists, addresses, or payment data.
When the $799 boundary is the wrong fit
- You need multiple unrelated business processes
- The task requires bypassing login controls or CAPTCHAs
- You need server installation or ongoing operations
- The automation would make final financial, medical, or legal decisions
- Testing is impossible without real customer data
Those jobs should be split into smaller safe units or handled under a different engagement.
CHECK THE FIT
If you can describe the job as one operational process with up to three connected workflows, it may fit the 72-hour sprint. A public messenger handle and anonymous examples are enough for the first scope check.
