Choosing a business process automation platform is harder than the marketing pages from each vendor suggest. The wrong choice locks you into the wrong abstraction level for years. The right choice scales with your business and your team. This guide walks through the practical decision framework we use when consulting with B2B and SaaS clients on automation platform selection.

The four main categories of automation platforms

Most automation work falls into four platform categories. Pure no-code (Zapier, Pipedream, Tray.io) for fast prototypes and simple workflows. Hybrid low-code (n8n, Make, IFTTT) where visual workflows can drop into code where needed. RPA platforms (UiPath, Automation Anywhere, Blue Prism) for desktop and legacy system automation. Custom code (Python services on AWS Lambda, Node services on Cloud Functions) where the other three do not fit.

Most B2B teams need a mix. The question is which platform serves the bulk of your work and which handles the edge cases.

When pure no-code (Zapier) is the right call

Zapier wins for non-technical teams that need to ship simple integrations between SaaS tools they already use. It is fast, well-documented and reliable. Limits show up when workflows get complex (more than 10-15 steps), data transformations need real logic, or per-execution costs scale with usage.

Use Zapier for: single-step or simple multi-step automations between popular SaaS tools, fast prototypes to prove ROI before investing in custom work, automations where the «user» is a non-technical operations person who needs to be able to edit it themselves.

When n8n or Make become the better choice

n8n (open source, self-hostable) and Make (formerly Integromat) sit between Zapier and custom code. They handle complex workflows that Zapier struggles with, can drop into JavaScript code blocks for custom logic, and cost less per execution at scale. n8n specifically is popular for teams that want full control over data residency and want to avoid per-execution pricing entirely.

Use n8n or Make for: workflows with 10+ steps, automations that need custom logic between integrations, scenarios where data sensitivity rules out cloud-only platforms (n8n self-hosted), and high-volume automations where Zapier per-task pricing becomes expensive.

When RPA platforms (UiPath) are non-negotiable

RPA platforms automate processes that involve desktop applications without proper APIs. The classic case is legacy enterprise systems that have a Windows GUI but no programmatic interface. Or processes spanning multiple desktop apps that need a «robot» mimicking what a human would click.

RPA is expensive (license costs scale fast) and brittle (UI changes break the bot). Avoid it when API integration is possible. But for legacy enterprise environments where API access is genuinely unavailable, RPA platforms remain the only practical choice. UiPath is the market leader; Microsoft Power Automate Desktop is a budget alternative.

When custom code beats every platform

Custom Python or Node services beat every platform when business logic is unusual enough that no-code workflows become unreadable, when scale demands sub-second response times that workflow engines cannot deliver, when data sensitivity requires hosting on your own infrastructure with no third-party services, or when you have an existing engineering team that prefers ownership over external platforms.

Custom code costs more upfront but pays back in flexibility, performance and control. We see teams hitting the wall around 25-30 active workflows on a no-code platform — at that scale, custom services usually deliver better total cost of ownership.

Realistic costs across platform categories

Pure no-code (Zapier): $20-300 per month for small teams, scales aggressively with task volume — easy to hit $1,000+/month for active accounts. Hybrid low-code (n8n self-hosted): infrastructure costs only, typically $20-200/month for small teams; Make starts at $9/month and scales similarly to Zapier. RPA (UiPath): enterprise pricing, typically $5,000-50,000/year per environment plus per-bot fees. Custom code: development cost upfront ($3,000-30,000 per workflow depending on complexity) plus hosting ($10-500/month).

The catch: total cost of ownership at scale usually flips the economics. Zapier looks cheap at $50/month but expensive at $2,000/month. Custom code looks expensive at $20,000 upfront but cheap at $200/month for years.

Common platform-selection mistakes

Three patterns we see derail automation programs. First, choosing one platform «for everything» instead of the right tool per use case. Second, picking based on the cheapest sticker price without modelling cost at projected scale. Third, buying a platform without buying expertise — owning a license to UiPath does not make your team productive in it.

Mitigation: pilot two platforms in parallel for the first three workflows, model 12-month cost at expected volume not current volume, and budget for either internal training or external implementation help.

Decision framework for your specific case

Run through these questions in order. Is the process across SaaS tools with proper APIs? Yes → start with Zapier or n8n. Is the volume more than 10K tasks per month? Yes → look at n8n self-hosted or custom code over Zapier. Does data sensitivity rule out cloud platforms? Yes → custom code on your infrastructure or n8n self-hosted. Is the process trapped in legacy desktop apps? Yes → RPA is your only option. Do you need sub-second response times for user-facing automations? Yes → custom code.
