API Integrations & Business Automation
Stop copying orders, invoices, and stock between systems by hand. We connect your ERP, store, CRM, couriers, marketplaces, and e-Factura so data moves on its own, with retries, logs, and an alert when something fails.
Written reply within one business day, with the simplest way to connect it.
Delivered with every integration
- A map of the data flow: which system owns which field, volumes, and failure points.
- Fixed estimate after a 1–2 day audit.
- A first sync on your real data, checked together field by field.
- Retries with backoff and idempotency, so a dropped webhook doesn't create duplicates.
- Logs for every run and an alert (Slack or email) when a sync fails.
- Automated tests on the API contracts you depend on.
- Code in your repository and keys in your accounts; nothing runs on credentials you don't own.
- Operations notes and post-delivery support.

Custom code or low-code (n8n, Make)?
Neither is better in general; volume and the cost of a failure decide.
- n8n / Make / Zapier for simple, low-volume workflows (under about 1,000 runs a day), popular SaaS with ready connectors, or a team that wants to edit flows itself.
- Custom code (Node.js, Python) for high volumes, low latency, complex logic with state and retries, exotic systems, or strict audit requirements.
Typical packages
- Simple, €1,500–€3,000: Stripe checkout, SendGrid email, Twilio SMS, calendar sync. 3–5 days, monitoring and 30 days of support included.
- Mid-tier, €3,000–€8,000: full e-Factura ANAF, two-way CRM–ERP sync, courier integration. 1–3 weeks.
- Complex, €8,000–€30,000+: a central hub syncing 5+ systems (store, ERP, CRM, marketplace, courier, e-invoicing). 4–12 weeks.
Four steps to a sync you can stop watching
Audit & estimate
1–2 days mapping the data flows, APIs, volumes, and failure points. You get a fixed estimate in writing.
Proposal & contract
Scope, deliverables, and acceptance criteria per system. Fixed price for defined integrations.
Build on real data
The first sync runs on your test data or samples; we check every field together, then harden it with retries, rate limiting, and logs.
Handover & monitoring
Code and credentials handed over, alerts on failed runs, a simple health report, and post-delivery support.

Questions about integrations
How much does an API integration cost?
Simple integration (Stripe, SendGrid): €1,500–€3,000. Mid-tier with two-way webhooks: €3,000–€8,000. Complex ERP–CRM–e-commerce integration: €8,000–€30,000+. Hosting, monitoring, and optional SaaS licences are separate monthly costs.
Do you use n8n, Make, Zapier, or custom code?
It depends on volume and complexity. For simple, low-volume workflows, n8n (self-hosted) or Make. For high volumes, low latency, or complex logic, custom code in Node.js or Python.
Do you integrate legacy systems without public APIs?
Yes. Options include read-only database access, file exchange (CSV or XML over SFTP), email parsing, reverse engineering internal APIs, and headless-browser automation as a last resort.
Do you monitor integrations after delivery?
Yes. Critical integrations get automated monitoring around the clock: alerts on failed webhooks, retries with exponential backoff, a success-rate view, and debug logs.
Who owns the credentials?
You. All API keys, secrets, and accounts are yours. We work with shared access during the project and hand everything over at the end.
