Zapier vs Make vs Custom Automation: Which Fits Your Business?

If you are automating workflows in a UK small or medium business, you will almost certainly consider Zapier or Make first — and for plenty of tasks, one of them is the right answer. They are cheap to start with, quick to set up, and connect to thousands of apps without writing code. But both are built around a pricing model and a logic model that eventually strain, and that is where custom workflow automation earns its keep.

This guide compares all three approaches on cost, capability, and long-term ownership. We build custom automation for a living, so read our position with that in mind — but we will be clear about the many cases where an off-the-shelf tool is exactly what you should use.

Zapier is the most approachable automation tool on the market. It connects more than 7,000 apps, the editor is genuinely friendly to non-technical users, and a simple “when a form is submitted, add a row to a spreadsheet and send a Slack message” zap can be live in ten minutes. For a UK SME with a handful of low-volume glue tasks, it is often the right call — full stop.

The catch is pricing. Zapier charges per task, and every step that moves data counts. As of mid-2026, paid plans start around $20–30 per month (Zapier prices in USD), but a business running a busy multi-step workflow — say 10,000–20,000 tasks a month — can find itself paying the equivalent of several hundred pounds monthly, forever. Costs scale with your success: the more your business grows, the more each automated process costs you.

Where it breaks down for UK SMEs: per-task pricing at volume; workflows needing loops, complex branching, or error handling beyond basic paths; steps requiring judgement rather than rules; and anything where an outage or silent failure in a rented platform carries real business risk. Zapier is also weakest when an app you rely on has a shallow integration — you get the triggers the connector exposes, and no more.

Make (formerly Integromat) is the power user's no-code tool. Its visual scenario builder supports routers, iterators, error handlers, and data transformations that Zapier either cannot do or charges heavily for. Pricing is also friendlier: as of mid-2026, paid plans start around $10 per month (priced in USD), and its per-operation model usually works out meaningfully cheaper than Zapier at equivalent volume.

The trade-off is complexity. Make's canvas rewards people who think like developers; non-technical staff often find scenarios hard to read and harder to debug. A moderately complex workflow becomes a sprawling diagram that only its author understands, and one operation-hungry loop can quietly burn through your monthly allowance. In practice, Make automations in SMEs tend to depend on one keen person — and become fragile when that person leaves.

Where it breaks down for UK SMEs: maintainability once scenarios grow; hidden operation costs on loops and polling; the same judgement-step ceiling as Zapier; and the same rented-platform dependency. Make narrows the gap to custom on capability, but it does not close it on ownership, reliability guarantees, or AI-driven decision steps.

Custom automation means a workflow built specifically for your business — typically integrating your actual systems via their APIs, with AI models handling the steps that need judgement: reading an unstructured email, extracting data from a document, classifying a request, or drafting a response for human review. You pay a one-off build cost (for most SME workflows, a few thousand pounds, depending on scope), then modest hosting and API usage. There are no per-task fees, so the cost per task falls as volume grows.

This is where the honest breakpoints sit. Custom wins when: volume makes subscription pricing painful (roughly 5,000+ tasks a month is where the maths starts to turn); logic involves judgement, unstructured inputs, or many-branch decisions; integrations you need are missing or shallow in the connector libraries; or ownership and reliability matter — the automation is yours, runs where you choose, and does not vanish with a subscription. One of our clients replaced a manual lead-research process that no-code tools could not handle — the judgement-heavy steps were the blocker — and you can read how in our lead research automation case study.

And the honest downside: custom costs more up front, takes weeks rather than minutes to deliver, and you need a partner (or in-house developers) to build and maintain it. If your workflow is simple and low-volume, that overhead is not justified — use Zapier. A quick way to check which side of the line you are on is our free workflow savings calculator: if the hours and cost tied up in a workflow are small, an off-the-shelf tool is almost certainly the right answer.

• Choose Zapier if your workflows are simple, low-volume (under a few thousand tasks a month), and non-technical staff need to build and change them. It is the fastest path to value and often all an SME needs.
• Choose Make if you need multi-step logic, transformations, or branching on a budget, and someone on your team enjoys building technical scenarios and will stick around to maintain them.
• Choose custom automation if your volumes make per-task pricing expensive, the workflow needs judgement or handles unstructured inputs, you need integrations the platforms do not offer, or you want an asset you own rather than a subscription you rent.
• Mix them if you are like most businesses: keep the simple glue on Zapier or Make, and go custom only for the one or two workflows where the economics clearly favour it.

If you are not sure which side of the breakpoint your workflow sits on, a 30-minute review is usually enough to tell — and if Zapier or Make is the right answer for you, we will say so.
