API and ERP integration: your systems, talking to each other.

We connect ERP, CRM, online store and payments so data travels on its own, with alerts when something fails.

Projects from €4,000Reply within one business day

Every event, where it belongs.

Orders, customers and stock synced with no manual copying.

If something fails, it retries on its own.

And it shows on the dashboard, with an alert if someone needs to step in.

One piece of data, everywhere.

Let's talk about your integration

Your systems, in sync with each other

CRM, ERP and online store pass orders, customers, payments and stock to each other as soon as something happens. Each connection shows when it last synced.

  • Store orders into the ERP
  • ERP payments into the CRM
  • ERP stock out to the store
Connections EmpresaQ S.L.
CRMCustomers and deals 2 min ago
ERPOrders, invoices and stock 2 min ago
Online storeCatalogue and web orders 2 min ago
  • Status of each connection If a system stops syncing, it shows here without digging through its logs.
  • Both ways The ERP receives the store’s orders and sends back stock availability.

And when a system fails, it retries

When the CRM rate-limits requests (a 429 error), the event is queued and retried with growing waits. Meanwhile, the other systems keep syncing.

Events to the CRM ERP → CRM
10:42:06 invoice.paid · attempt 1 429
10:42:08 customer.updated waits in the queue Queued
10:42:10 invoice.paid · retry 1/3, after 4 s 429
10:42:18 invoice.paid · retry 2/3, after 8 s 200 OK
10:42:18 customer.updated delivered from the queue 200 OK
  • The CRM is rate limiting It returns 429 Too Many Requests and asks for a 4 s wait.
  • Delivered, no data lost After waiting 4 s and then 8 s, both queued events reach the CRM.

And you see how each connection is doing

Events per day and p95 latency for each system, with the queue in view. Every event keeps its attempts, the data sent and the mapping applied.

Events today Per system
ERP 3,917 p95 146 ms
CRM 1,284 p95 182 ms
Online store 2,406 p95 121 ms
Queued 0 Recovered
  • After the outage CRM p95 goes up to 236 ms; the ERP and store figures do not change.
  • Queue empty The events that were waiting have been delivered.

Your systems, in sync and monitored

An online shop’s integrations hub connecting CRM, ERP and online store. When something fails, you see it and, if the failure is temporary, it recovers on its own.

  1. Orders, customers, payments and stock move between systems in real time.
  2. The CRM throttles requests and returns a 429 error for a payment event.
  3. The integration waits, retries automatically and the event is delivered.
  4. The detail view shows every attempt, the data sent and the mapping applied.

What changes day to day

Today

  • Data is scattered: CRM here, accounting there, spreadsheets everywhere
  • Someone moves data between systems by hand every day
  • Reports are out of date by the time they are ready
  • When a connection fails, nobody notices until something is missing

Once it is running

  • Your tools connected into one reliable flow
  • Data synced automatically, without exports or double entry
  • The same data in every tool, with no conflicting versions
  • If something fails, it is retried and someone gets notified

What is included

Connect the services you depend on

Payment gateways, CRM, ERP, online shop: we build a secure connection to each service your business uses and leave it monitored.

Your systems in sync

Data flows automatically between your ERP, CRM, accounting software and other tools, in both directions. No more manual exports or copy-pasting between systems.

Reacts to events instantly

When an order comes in, a payment is received or a ticket is opened, every connected system is updated at once.

Consistent data

When several systems share the same data, we build sync layers that keep it consistent and resolve conflicts by clear rules, to avoid duplicates and gaps.

Handles outside failures

If an external service is slow or temporarily unavailable, the rest of the integration keeps working. Events wait in a queue to be retried instead of being lost, and your team knows what happened.

Data translated automatically

Each system stores data in its own format. We handle the translation (field mapping, format conversion, deduplication) so everything arrives the way the receiving system expects.

Typical uses

  • Finance and e-commerce

    Payment gateway integration

    Connect Stripe, PayPal, Redsys or any payment processor to your platform so payments are captured, reconciled and reported without manual handling.

  • Sales

    CRM integration

    Keep contacts, deals and customer activity synchronised between your CRM (Zoho, Pipedrive, HubSpot…) and your own systems, up to date in both directions.

  • Management and data

    Centralised data for reporting

    We bring the data from all your tools into one place for reporting and analysis. Your team stops gathering it by hand.

  • Operations

    ERP integration with shop and logistics

    Connect your online shop, ERP, helpdesk, logistics and finance into one coherent flow, so an order placed online automatically triggers everything downstream.

How we keep risk under control

Every integration comes with monitoring and automatic retries. If a connection fails, you know about it.

  • Monitoring

    Every call and every sync is logged. A dashboard shows what went through, what is pending and what needs attention.

  • Automatic retries

    If an external service is slow or down, requests are queued and retried with backoff, respecting each provider’s limits.

  • Alerts

    When something cannot be resolved automatically, the right person is notified with the details, so they can act before it affects customers or reports.

  • Idempotency

    Each operation is designed so that repeating it has no side effects: a retried payment or order is recorded only once.

How we work

The timeline depends on scope and is set in writing in the proposal.

  1. Review what you have

    We start by understanding your current tools, how data moves between them today and where errors or manual workarounds cost you time.

  2. Design the connection

    We map how data will flow, what gets transformed along the way and how the integration behaves when something fails. All agreed in writing before we build.

  3. Build and test thoroughly

    We build against test environments and put every integration through realistic scenarios and edge cases before it touches your production data.

  4. Launch with support

    We deploy to production, monitor the first weeks closely and stay available to adjust, improve or extend the integration as your needs evolve.

Frequently asked questions

What happens if a third-party service changes or goes down?

We design for it: automatic retries, failure alerts and fallback logic limit the impact on your operations, and your team is notified if something needs attention.

How do you keep our credentials and data secure?

Credentials are stored securely and never hardcoded. Data in transit is always encrypted and we follow the principle of least privilege: each integration accesses only what it needs.

Can you connect to older or undocumented systems?

Usually, yes, including legacy systems, internal databases and undocumented APIs. We first analyse how the system behaves: if a connection is viable, we build a stable, maintainable one around it; if it is not, we tell you before we start.

Will the integration slow down if the external service is busy?

We build queuing and throttling into every integration, so it respects the limits of external services: under load, events wait in a queue instead of being dropped.

What if we need more integrations later?

We design the integration layer to be extended from the start. Adding a new connection later does not mean redoing what already works or being tied to a rigid setup.
