# n8n automation agency that also builds in Make and Zapier

> Integration work connects business tools such as your CRM, Gmail, Slack, accounting software and internal APIs so data moves between them automatically. We build in n8n, Make, Zapier or custom code, picked for your volume, budget and who will maintain it, with retries, error alerts and documentation. A single integration takes 1 to 2 weeks and costs $1,500 to $6,000; bundles run $8,000 to $20,000.

- Service: n8n, Make, Zapier and API integrations
- Category: Automation

We connect the tools your company already pays for, so records, messages and files move between them without anyone exporting a CSV. The platform is chosen for your volume and your team, and every integration ships with retries, alerts and a runbook.

## Key facts

- Price: $1,500 to $20,000 per project. $1,500 to $6,000 per integration; bundles of several integrations around one process run $8,000 to $20,000. Platform subscriptions are paid by you directly.
- Timeline: 1 to 6 weeks
- Typical tools: n8n, Make, Zapier, Microsoft Power Automate, TypeScript, Python, Docker, Postgres, Slack API, Gmail API, Microsoft Graph, HubSpot API, Salesforce API, Xero API, QuickBooks Online API
- Change requests: $175 an hour, quoted in writing first
- Model and tool usage: billed to your own accounts at cost, no markup
- Ownership: code, workflows, prompts, accounts and data belong to you

## Who it is for

- Teams that have chosen n8n, Make or Zapier and want it built properly the first time
- Companies whose tools do not talk to each other, so staff copy data between them
- IT and ops leads who need integrations self-hosted for data or compliance reasons
- Businesses whose existing Zaps and scenarios fail often and nobody can say why

## Signals you need it

- **Someone exports a CSV every Monday.** Data moves between systems by download and upload, on a schedule set by one person's calendar.
- **Customers find your failures first.** An integration stopped running weeks ago, and you learned about it when an order, invoice or lead went missing.
- **Your Zapier bill keeps climbing.** Task counts grew with the business, and you are paying per step for work that could run for less on another platform or in code.
- **A tool you depend on has no connector.** The app directory does not list it, or the connector lacks the endpoint you need, so the work stays manual.

## What we hand over

- **Integration spec.** One page per integration: trigger, systems, field mapping, expected volume, error handling and the person who owns it.
- **Working integrations on your accounts.** Built in n8n, Make, Zapier or TypeScript, with credentials held in your accounts and nothing running on ours.
- **Error handling and alerts.** Retries with backoff for temporary failures, a holding queue for records that cannot be processed and a Slack or email alert with the failing record attached.
- **Version history.** n8n workflows and custom code exported to your repository and Make scenarios saved as blueprints, so any earlier version can be restored.
- **Runbook.** What each integration does, what each alert means, how to pause it and how to replay failed records once the cause is fixed.

## How the engagement runs

1. **Map** (1 to 5 days): We list the systems, check their APIs and plan limits, measure volumes and write the integration spec. You get a platform recommendation with running costs and the spec the build is tested against.
2. **Prove** (1 to 5 days): We connect to each system with real credentials in a test workspace and push sample records through. That is where undocumented API quirks show up, and if an API cannot do what the spec needs, you hear it now.
3. **Build** (2 days to 4 weeks): We build with error handling, logging and alerts, test against duplicates, missing fields and rate limits, then go live with monitoring on. Bundles go live one integration at a time.
4. **Run** (Monthly, optional): APIs change and credentials expire. On a care plan we watch every run, renew connections and absorb vendor changes. Or your team owns it with the runbook.

Every engagement follows [The Method](https://methodcrew.com/approach): Map, Prove, Build, Run.

## Which is better for business automation: n8n, Make or Zapier?

The right platform depends on your volume, your data rules and who will maintain the integration after we leave. All three connect hundreds of common business apps, and all three can call almost any API through an HTTP step. They differ in how they bill, where they run and how much code they tolerate.

| | Zapier | Make | n8n | Custom code |
|---|---|---|---|---|
| Hosting | Zapier cloud only | Make cloud only | n8n Cloud, or self-hosted on your server | Your cloud account |
| Billing unit | Tasks (each successful action) | Credits (most module runs use 1) | Executions on Cloud; no execution fee self-hosted | Hosting only |
| Best owner after handover | Non-technical ops staff | Ops staff comfortable with logic | Technical ops or an engineer | An engineer |
| Strong at | Breadth of connectors, fast setup | Visual branching and data mapping at low cost | High volume, code steps, data kept in-house | Complex logic, strict performance needs |
| Watch for | Cost at high task volumes | Credit use in loops over large lists | Patching and backups when self-hosted | Every change needs a developer |

Make moved its billing from operations to credits in August 2025 ([Make help center](https://help.make.com/introducing-credits-new-billing-unit-live-in-make)). n8n's free Community Edition can be self-hosted, while features such as SSO, environments and Git-based version control need a paid plan ([n8n docs](https://docs.n8n.io/choose-how-to-use-n8n/)).

Our default: Zapier for small, low-volume flows owned by non-technical staff, Make for mid-volume logic, n8n when volume, cost or data location matters. The longer comparison, with worked cost examples, is in [n8n vs Make vs Zapier](https://methodcrew.com/insights/n8n-vs-make-vs-zapier).

## When do you need a custom API integration instead of a no-code tool?

Most integrations belong on a platform, because your team can see and change them there. We write custom code when one of these holds:

- Volume is high enough that per-task or per-credit pricing costs more than a small server. Syncing 200,000 records a day is usually cheaper in code.
- The logic is heavy: multi-step reconciliation, fuzzy matching between systems or calculations your finance team needs to audit line by line.
- Latency matters. A customer-facing action that has to finish in under a second should not wait in a platform queue.
- The connection is unusual: mutual TLS, SOAP services, SFTP drops, signed requests or on-premise systems behind a VPN.
- Your engineering team wants it in their repository, with code review, tests and deployment like any other service.

There is a middle path: n8n with code nodes. n8n lets you write JavaScript or Python inside a workflow, so the hard part is real code and the plumbing stays visible to the ops team. Self-hosted n8n can also reach systems inside your own network.

When we do write code, it is TypeScript or Python, deployed to your cloud account with tests, logging and a README. It belongs to you like everything else we build.

Before any of that, check for a native integration. If a vendor already offers one that covers your fields, such as HubSpot's built-in Gmail and Outlook sync, we will point you to it and save you the build.

## What happens when an integration fails at 2am?

It retries, then it tells someone. Every integration we build separates temporary failures from permanent ones and treats them differently.

Temporary failures (a rate limit, a timeout, a vendor outage) retry on their own with growing gaps between attempts, for example after 1, 5 and 30 minutes. Most clear without anyone waking up.

Permanent failures (a missing required field, a deleted record, an expired credential) stop at once. The record moves into a holding queue so nothing is lost, and a named person gets a Slack or email alert with the record, the error and a link to the log. When the cause is fixed, they replay the queue in one step.

Three design rules prevent the worst outcomes:

- Idempotency. Every write carries a unique key, so a retry cannot create a second invoice or a duplicate contact.
- Write order. The system of record is written last, so a failure halfway through leaves nothing half-created there.
- Heartbeats. A scheduled check raises an alert if an integration has not run when it should have, which catches the silent failures that error alerts miss.

n8n offers an Error Trigger workflow for this and Make offers error handlers on each module. We use both, then add the holding queue and alerts on top. Overnight monitoring and fixes come under an [automation care plan](https://methodcrew.com/services/automation-care-plans).

## How much does it cost to hire an n8n or Zapier expert?

With us, a single integration costs $1,500 to $6,000 and a bundle of several costs $8,000 to $20,000, as a fixed price agreed in writing before work starts. Changes after handover are billed by the hour, or come under a care plan.

| Scope | Example | Price | Timeline |
|---|---|---|---|
| Simple integration | A new Typeform response creates a HubSpot contact and posts to Slack | $1,500 to $2,500 | Under 1 week |
| Standard integration | Two-way sync between CRM and accounting, with matching and an error queue | $3,000 to $6,000 | 1 to 2 weeks |
| Bundle | 4 to 6 integrations around one process, such as order, invoice and fulfillment | $8,000 to $20,000 | 3 to 6 weeks |

What moves the price: two-way sync (much harder than one-way, because conflicts need rules), the number of fields and record types, the quality of each API, volume, and whether we self-host n8n for you.

Freelance rates on marketplaces start lower, and for one simple Zap that can be the right call. The fixed price here pays for the spec, error handling, monitoring setup, documentation and a named person accountable when something breaks.

Platform subscriptions sit outside our fee. You pay Zapier, Make or n8n directly, on your own account, and we size the plan to your volume during Map. Self-hosted n8n needs a small server, usually with the cloud provider you already use.

## When do you not need us, and what is not included?

You do not need us for a two-step Zap that copies a form response into a spreadsheet. Zapier and Make are designed for exactly that, and someone on your team can set it up in an afternoon. Bring in help when an integration moves money or customer records, or when a failure would take real time to clean up.

You may not need a build at all if a vendor already offers a native integration that covers your fields. Check the app marketplaces of your CRM and accounting tool first. We run that check during Map and tell you if it settles the question.

Not included in integration work:

- Platform subscriptions, API plan upgrades or server costs. You pay those directly, at cost, with no markup from us.
- Fixing the source systems. If the CRM has 3 fields for the same thing, we map to one, but deduplicating the CRM is a separate piece of [sales and CRM automation](https://methodcrew.com/services/sales-crm-automation) work.
- Process redesign. If an integration exposes a broken process, the fix belongs in [business process automation](https://methodcrew.com/services/business-process-automation).
- Reading documents or free text. Integrations that need to understand an email or a PDF need a language model step, which is [AI automation](https://methodcrew.com/services/ai-automation).

## What changes for your team

- A record created in one tool appears in the others within minutes, with no exports
- Failures alert a named person, with the failing record attached, before a customer notices
- Failed records wait in a queue and can be replayed once the cause is fixed
- Platform costs match your actual volume, with the reasoning written down
- Your team can read, pause and change each integration using the runbook

## Common questions

### Can n8n be self-hosted?

Yes. n8n's free Community Edition runs on your own server or cloud account, usually in Docker, under n8n's Sustainable Use License, which allows internal business use. Self-hosting suits teams with strict data rules or high volumes. Someone has to patch and back up the server; we set that up and can run it on a care plan. SSO needs a paid n8n plan.

### Do you build on Microsoft Power Automate?

Yes, when it fits. Power Automate makes sense for companies standardized on Microsoft 365, because it connects directly to SharePoint, Outlook and Teams, and many of its standard connectors come with Microsoft 365 licenses. Premium connectors cost extra, so we check your licensing in Map. We will not move you off a platform that works just to suit our own preferences.

### Can you migrate our Zaps to n8n or Make?

Yes. We inventory your Zaps, drop the ones nobody uses and rebuild the rest on the new platform with proper error handling. Old and new run in parallel for a few days before each Zap is switched off. Migration makes sense when task volume has grown enough that the monthly bill outweighs a one-off rebuild, and we show that comparison before you decide.

### How do you handle API keys and passwords?

They stay in your accounts. Credentials live in the platform's credential store or your cloud secrets manager, under service accounts you own, with the narrowest permissions each integration needs. We do not keep copies. At handover we list every credential, what it can access and when it expires, and we rotate anything used during the build.

### Can you connect Slack and Gmail to our CRM?

Yes. Typical builds: a Slack alert when a high-value lead arrives, Gmail threads logged against the right CRM contact, a Slack shortcut that creates a deal, or a daily digest of overdue tasks. If your CRM already syncs email natively, we use that and build only what it misses.

### What if a vendor changes its API?

Major vendors usually announce breaking changes in advance and keep older API versions running for a period. We pin API versions where vendors allow it and track deprecation notices for the systems we connect. On a care plan we make the update before the old version is switched off. Without one, we quote the change at $175 an hour when you need it.

### How long does a single integration take?

A simple one-way integration goes live in under a week from signed scope. A two-way sync between a CRM and an accounting tool takes 1 to 2 weeks, mostly spent on matching rules and edge cases. Bundles of 4 to 6 integrations take 3 to 6 weeks. The usual cause of delay is waiting for API access or admin rights, so we request them on day 1.
