🚀 How n8n Helps BikUp Automate a Fast-Growing Marketplace from Marketing to Accounting

Feedback

Hi everyone!
I’m Hugo, co-founder of BikUp, a fast-growing bike-rental marketplace launched in early 2025. We help people all across France rent their bike (cargo, gravel, road, e-bike…) to others nearby. Think Airbnb, but for bikes — simple, local and sustainable.

We’re only two running the entire company, and the growth has been intense. With traction comes responsibilities:

  • regulatory obligations,

  • financial reporting,

  • customer communication,

  • fraud checks,

  • DAC7 compliance,

  • marketing workflows,

  • and everything that comes with running a marketplace.

Very quickly, we realized that we couldn’t scale without automation.
And this is exactly where n8n became a core part of our infrastructure.

:wrench: Why n8n Became Essential for BikUp

When you’re two founders managing a national marketplace, the challenge is simple:
automate everything that can be automated — reliably, transparently, and with full control.

n8n gives us:

  • a self-hosted, privacy-friendly workflow engine,

  • the freedom to integrate any API (Stripe, ERPNext, PostHog, MailerSend…),

  • the ability to ship automation for things we’d normally need a backend engineer for,

  • the flexibility to adapt quickly as regulations change.

We now run dozens of workflows that save us several hours every day.

:open_mailbox_with_raised_flag: How We Use n8n Today

Here’s a concrete overview of what we automated using n8n.

1. Marketing & User Activation

  • Automated welcome emails based on user type (owner / renter)

  • PostHog → CRM sync to segment users

  • Automated reminders for incomplete profiles

  • WhatsApp & email alerts when a listing is missing photos or pricing

  • Monthly rentability report sent automatically to bike owners

2. Operations & Marketplace Management

  • Fraud detection checks based on velocity, location patterns, bike photos

  • Alerts when a booking looks suspicious

  • Automatic enrichment of bike listings (brand/model parsing)

  • Automatic user notifications (renewals, updates, damage checklist)

3. Accounting & Regulatory (DAC7)

This is where n8n saved us days of manual work.

  • Sync every booking to our ERP (Dokos → ERPNext)

  • Automatic VAT categorization

  • Generating accounting journal entries via API

  • Sending curated monthly ledgers to our accountant

  • Preparing DAC7 data exports

  • Cross-checking payouts between Stripe and ERP

  • Matching owner payouts with their invoices

This was previously a nightmare for a tiny team — n8n turned it into a predictable pipeline.

:hot_beverage: The ROI for a 2-person Startup

We always say internally:
“If n8n shuts down, we shut down too.”
Not because we depend on it blindly, but because it became the backbone that lets two people run a company that looks like a team of 10.

Some real benefits:

  • Several hours saved every single day

  • Near-zero manual accounting

  • Faster user response time

  • Instant partner onboarding

  • No-code ability to ship features that normally require backend dev time

  • Faster regulatory compliance (especially DAC7)

  • A more scalable, more resilient marketplace

I don’t think BikUp could have grown this quickly without it.

:heart: A Huge Thanks to the n8n Community

Every time we hit a roadblock, the community helped.
Every weird API call, webhook design, OAuth quirk — someone already had an answer.

We wanted to share this story to say: for small teams building real-world businesses, n8n is a superpower.

If some of you are curious, I can also share:

  • how we structure our workflows,

  • how we connect Stripe / ERPNext / PostHog / NocoDB together,

  • how we replaced dozens of SaaS tools using n8n alone.

Just let me know — always happy to contribute back.
