If your business works like this,
you are losing time, leads
and data
.

The problems that push a business towards a connected digital system are not technical: they are operational. If you recognise 3 or more, we should talk.

You have Shopify, Workspace, WhatsApp, Ads and a CRM, but none of them talk to each other.

Leads come in through forms, WhatsApp and campaigns, but they get lost or go cold.

Your team works on manual spreadsheets that no longer scale.

You invest in Ads but do not know which campaign drives real sales.

Shopify sells, but reporting and post-purchase are manual.

You want to apply AI but do not know where it would have real impact.

What we do

Digital systems architecture,
not patches.

FlowSystem does not sell loose workflows or software from scratch. We design lightweight systems that connect, organise and automate what you already have — adding only what is essential on Google Cloud.

01

We connect platforms

Your current tools talk to each other via API, webhooks and events instead of manual copy/paste.

02

We automate flows

Repetitive processes run on Cloud Run, Cloud Functions and Apps Script — not on spreadsheets.

03

We structure data

Events, conversions, orders and leads are centralised in BigQuery with dashboards in Looker Studio.

04

We apply AI

Gemini and Gemini API inside the system: scoring leads, summarising conversations, enriching records.

05

We build on cloud

Google Cloud as the foundation — scalable, observable and maintainable — with no proprietary software lock-in.

Implementable systems

Four replicable
operating
engines.

Each Engine is a closed system with architecture, integrations, dashboards and documentation. We do not reinvent the wheel with each client — we adapt it.

Before & after

Same team, no copy-paste.

Before — business without a system

Fragmented manual operations

  • Leads arrive via WhatsApp, email and Ads without being logged anywhere.
  • Shopify orders are copied to Excel for reporting.
  • Sales team answers the same questions five times a day.
  • Ad campaigns are evaluated by gut feeling, not by data.
  • Workspace full of loose files with no clear permissions.
After — with FlowSystem

Digital operating system

  • Every lead enters the CRM scored by AI and notified to the team.
  • Orders trigger post-purchase WhatsApp messages and feed BigQuery.
  • Approvals, alerts and documents generated without manual intervention.
  • Looker connects ad spend to real sales.
  • Workspace organised with automatic flows and defined permissions.

Positioning

We are not what it seems.
We are what your business truly needs.

What we are not

  • Make / Zapier / n8n freelancers living off templates.
  • An Ads agency that manages campaigns and reports clicks.
  • A web studio delivering landings with no operation behind them.
  • A software house rewriting your stack from scratch.
  • A slow, over-sized enterprise consultancy.

What we are

  • Lightweight architecture on Google Cloud, APIs and applied AI — not no-code patches.
  • We build the data and automation infrastructure that lives behind your campaigns.
  • We connect web, CRM, Shopify, WhatsApp and data as a single operating system.
  • We organise, connect and automate the stack you already use; we add only what is essential.
  • Modular and replicable systems, not one-off artisanal projects.
Technology

Cloud-first
stack, no shortcuts.

Google Cloud at the core. Real enterprise tools for marketing, ecommerce and operations. Make and n8n live as bridges, not as the backbone.

Process

From diagnosis
to system in
4 phases.

We work by concrete deliverables, not by open-ended hours. Each phase has scope, deliverable and defined next step.

Implementation

Optimisation

Light support or retainer: monitoring, improvements, new flows and adjustments as the business evolves.
