Zapier vs Make vs Custom Automation: Which Type Suits Your Business?
Choosing between a no-code platform and a custom build is less about which tool is 'better' and more about how your business actually needs it to behave over time.
In short
No-code platforms like Zapier and Make suit simple to moderately complex workflows connecting standard apps, where speed of setup matters more than deep customisation. Custom automation suits workflows with complex logic, high transaction volumes, bespoke systems, or strict governance and auditability needs. Many businesses use a mix: no-code for simple connections, custom build for the processes that matter most commercially.
Zapier and Make are two of the best-known no-code automation platforms, letting businesses connect apps and automate steps without writing software. Custom automation means building a bespoke system, sometimes using these platforms as a base, sometimes written independently.
The right choice depends less on brand preference and more on how complex, sensitive and long-lived the workflow needs to be. Vendor pricing for any of these platforms changes regularly and should always be checked directly rather than assumed.
What these options actually are
- No-code automation platform
- A visual tool, such as Zapier or Make, that connects different software applications and automates steps between them using pre-built templates and connectors, without writing code.
- Custom automation
- A bespoke solution built specifically for a business's systems and processes, which may use a no-code platform as part of its foundation or be built independently, typically used where standard templates cannot handle the required logic or scale.
Simplicity versus flexibility
No-code platforms are designed to be usable by non-developers, with visual flows and pre-built connectors to thousands of common apps. This simplicity is their strength and their limit: they handle straightforward 'when X happens, do Y' logic well, but become harder to manage once a workflow needs complex conditional branching, bespoke calculations, or integration with a system that has no ready-made connector.
Custom automation removes that ceiling. It can handle whatever logic a business genuinely needs, connect to internal or legacy systems without a pre-built connector, and be shaped exactly around a specific process. The trade-off is that it takes longer to build and needs a developer or specialist to create and later adjust it.
Integrations: breadth versus depth
Zapier and Make both offer very broad integration libraries, covering most mainstream CRM, accounting, email and marketing tools. Where a business uses standard, well-known software, this breadth is a genuine advantage. Where a business relies on an industry-specific or internally built system, no-code platforms may not integrate cleanly, and custom-built connections become necessary regardless of which other tool is used alongside them.
Complexity and where each option strains
No-code platforms can become difficult to manage once a workflow involves many linked steps, multiple conditional paths, or needs to process large volumes reliably. At that point, workflows become hard to read, debug and hand over to someone else. Custom automation is built to handle this complexity from the outset, but requires proper documentation and a maintenance plan of its own to avoid becoming just as opaque.
Maintenance and who can support it
A no-code workflow can usually be maintained by the person who built it, or handed to a reasonably confident colleague, provided it is documented. A custom build generally needs ongoing developer or specialist support, which is a genuine ongoing cost but comes with more control over exactly how the system behaves and evolves.
Scalability
No-code platforms can hit practical limits as volume grows — in processing speed, in how many steps a single flow can sensibly contain, or in cost structures tied to the number of operations run (vendor pricing should be checked directly, as it varies and changes). Custom automation scales more predictably for high-volume or business-critical processes, at the cost of more upfront investment.
Governance and auditability
Where a process touches customer data, financial information or anything requiring a clear audit trail, the ability to log, review and control exactly what the automation did matters. No-code platforms offer some logging, but custom automation can be built with governance requirements designed in from the start — useful where approval steps, audit trails or data handling rules are non-negotiable.
Comparison
| Factor | No-code (Zapier/Make) | Custom automation |
|---|---|---|
| Speed to build | Fast | Slower |
| Handles complex logic | Limited | Strong |
| Integration breadth (standard apps) | Very broad | As built |
| Integration with bespoke/legacy systems | Often limited | Strong |
| Maintenance | Often self-manageable | Needs ongoing specialist support |
| Scalability for high volume | Can hit practical limits | Built for scale |
| Governance/audit trail | Basic | Can be designed in fully |
| Best suited to | Simple, standard-app workflows | Complex, sensitive or high-volume processes |
A blended approach is often the right answer
Many businesses do not need to choose one option exclusively. Simple internal notifications or standard app connections can sit comfortably on a no-code platform, while the processes that matter most commercially — quoting, customer onboarding, financial reporting — justify a custom-built, properly governed approach. The decision should be made process by process, not as a single blanket choice for the whole business.
Risks and limitations
No-code platforms carry the risk of workflows growing organically into something nobody fully understands, often built by someone who has since moved on. Custom builds carry the risk of vendor or developer dependency if not documented and handed over properly. Neither option removes the need for a named owner and a maintenance plan.
How Evans approaches this choice
Evans does not default to recommending a custom build where a no-code platform would genuinely do the job, nor the reverse. The free automation diagnostic and an AI Workflow Audit (£1,495 + VAT) assess the actual complexity, sensitivity and volume of a process before recommending which approach fits — including, sometimes, that no automation is needed at all.
