How we work

An integration is done when it alerts you on its own

Every connection ships with automatic retries, a log of every record and email or WhatsApp alerts. You find out before your customers do.

Integration recipes for your business

Pick an area and see step by step what happens when your systems are connected: what triggers it, what each system does and what you gain.

So accounting balances itself

ERP and accounting

Customers, products, inventory, orders and invoices synced with SAP, Odoo, Dynamics and local accounting software.

How it works

When an order or sale is confirmed
1The order arrives with customer, products and taxes
2The customer is created or updated in the ERP
3Inventory is deducted from the right warehouse
4The sale is recorded in accounting
5The day closes without cross-checking spreadsheets

How data travels

Every record, from source to destination, never lost

Between your systems we place an integration layer that takes every record through six steps. You see it all in a live log: what was delivered, what was retried and what needs your attention.

Sources

Online store
Payment gateway
Forms and ads
WhatsApp
Mobile app

Integration layer

1ValidatesFormat, required fields, signature and duplicates.
2TransformsTranslates each record into the destination's format.
3OrdersQueues that process in order even when thousands arrive.
4RetriesIf a system doesn't answer, it tries again on its own.
5LogsWhat came in, what went out and how long it took.
6AlertsEmail or WhatsApp alert if something doesn't go through.

Your integration team

Specialists in making data arrive, always

Your integrations are built by a team that understands APIs, data and operations, with one accountable owner in front of you.

An integration architect as your technical point of contact
Data contract approved before coding
Testing with real data in a separate environment
Monitoring and alerts from day one in production

Engynex integration team

Team size adjusts to the number of systems and data volume.

What changes when your systems talk

Less typing, fewer errors and up-to-date data everywhere. Here's before and after.

TodayIntegrated

Data: Today: Copied by hand from one system to another; Integrated: Flows on its own, in real time or every few minutes
Errors: Today: Typos, duplicates and numbers that don't match; Integrated: Automatic validation before saving each record
Timeliness: Today: You work with yesterday's information; Integrated: Orders, inventory and payments updated in minutes
Failures: Today: You find out when a customer complains; Integrated: Immediate alert and a log of what happened
Growth: Today: More volume needs more people typing; Integrated: More volume with the same team
Vendors: Today: Every system is an island; Integrated: A connected, documented ecosystem

Results in weeks

We start with the connection that removes the most manual work and move on to the rest.

Your team stops copy-pasting

Hours of data entry become time to sell, serve and analyze.

You know everything is up to date

A dashboard shows what synced, what was retried and what needs attention.

Integrations for every industry

Every sector has its own systems and rules; we know them.

Retail and e-commerce
Store, ERP, POS, marketplaces and carriers with one inventory.
Logistics
Orders, routes, labels, proof of delivery and live status.
Manufacturing
Production orders, purchasing, quality and ERP connected.
Finance
Payments, reconciliation, origination and regulatory reports.
Healthcare
Scheduling, medical records, authorizations and billing.
Education
Enrollment, payments, course platform and admissions CRM.
Professional services
CRM, projects, timesheets, contracts and billing.
Public sector
Procedures, one-stop shops, interoperability and open data.

Reliable and secure

Connected, monitored and protected.

An integration handles your business's sensitive data. We design it to never lose a record and to keep everyone out of what they shouldn't see.

OAuth 2.0, rotatable keys and least privilege
Encrypted credentials, never in the code
Audit log of every message
Data handling under data protection law

Helix Assistant

AI assistant that answers clients and automates support for a fintech.

The challenge

FAQs

If it has an API or database, almost always yes. We assess each case with no commitment.

It's the door that lets two programs exchange information securely and automatically.

When it fits, yes (Zapier, Make). For complex cases we build custom integrations.

We look for alternatives: scheduled exports, direct database access or interface automation. We assess it at no cost before quoting.

Every integration includes event logging, automatic retries and email or WhatsApp alerts when something doesn't go through.

When it fits, yes: they're faster and cheaper for simple flows. For high volumes or complex logic we build a custom integration.

It depends on each system. With webhooks data arrives in seconds; when a system doesn't notify, we check every few minutes. We define it in the data contract based on what your operation needs.

Credentials are encrypted and in your name, never in the code. We use least privilege, encrypted traffic and an audit log of every message.

Yes. We design and publish your API with OpenAPI documentation, access keys, rate limits and a sandbox so customers or partners can connect on their own.

Custom integrations don't charge per task run; only the server they run on and the support you choose. With Zapier or Make you pay the tool's monthly fee based on your volume.
