Stock on the site is not the real stock
You sell products you no longer have, or hide products you do. Manual updates are always behind.
An order cancelled for lack of stock costs you the margin plus the customer.

ERP and API integration: your systems, finally connected
We connect stock management, invoicing, your CRM and your online store, so data gets entered once instead of three times.
The most expensive problem in a company is rarely a missing system. It is that the systems you already own do not talk to each other. We build the bridges over API or web service, across hundreds or thousands of records.
We reply the same working day. No obligation.

Situations
Three signs you need an integration.
The same data is entered several times
The order arrives on the site, then someone re-keys it into stock, issues the invoice and creates the shipping label.
You have no single view of the customer
The data sits in the store, in the CRM, in invoicing and in email marketing. No system holds all of it.
Benefits
Two-way synchronisation
Stock and prices from your management system to the store, orders and customers back the other way.
High volumes without bottlenecks
Hundreds or thousands of records processed in batches, without slowing the site down.
Invoicing without intervention
The invoice is issued on order and reaches the customer automatically, even at high volume.
Errors surface, they do not vanish
Every sync has a log, automatic retry and an alert on failure.
What you get
What an integration project includes.
A good integration is invisible. You only notice it when it is missing.
Types of integration
What we connect most often.
ERP or stock system to online store
Any platform that exposes an API: products, prices and stock updated automatically, with orders sent back.
Automated invoicing
The invoice is issued on order, sent to the customer and recorded in your accounting system.
Carriers and shipping labels
Correct delivery cost calculation, automatic label generation, tracking sent to the customer.
CRM and sales workflows
Leads from the site and from campaigns land in the CRM automatically, with their source and context intact.
Email marketing and automation
Contacts and events synced to Mailchimp, Klaviyo or Omnisend, with segmentation based on real behaviour.
Marketplace integration
Products and stock propagate from your system to marketplace channels, with one source of truth.
Process
Five steps, verified on real data.
System inventory
What you use, what API each exposes, what limits it has and who holds the credentials.
Mapping and proposal
Field correspondence, flow direction, frequency, and a proposal by module with estimated hours.
Build in a test environment
We implement and run against real data without touching production.
Parallel running
The integration runs alongside the manual process until the results match exactly.
Production and monitoring
Full switch-over, with logging, alerts and support through the first weeks.
How we build
Integrations that survive volume and failure.
The difference between an integration that holds and one that breaks monthly is not the connection itself. It is what happens when something goes wrong: server unavailable, incomplete data, API rate limits.
Our approach
API, web service and batch processing
We connect to your system through the interface it already exposes — REST or SOAP — without modifying your management software. Synchronisation runs in scheduled batches for high volumes and instantly for critical events such as a new order or a stock change.
- High volumes without bottlenecksBatch processing with rate limiting, so the source server is never overloaded.
- Error handling from the startAutomatic retry, complete logging, alerts on repeated failure. Nothing disappears quietly.
- Two-way synchronisationStock and prices one way, orders and customers the other, without conflicts.
- Verified on real dataWe run in parallel with the manual process until the results match completely.
- Minimum necessary accessSecure authentication and permissions limited strictly to what the integration needs.
- Built to growAdding a second system does not mean rewriting the first.
On the Hypericum project we built the web service integration between the stock management software and the online store: products, prices and stock levels update themselves across hundreds of lines.
Worth knowing: the integration depends on what your system exposes. If your management software has no API or web service, we check the alternatives together before we estimate anything.
Invoicing and accounting
The invoice is issued automatically when the order is placed, sent to the customer and recorded. At high volume the issuing runs asynchronously so it never slows checkout.
Suited to any store with more than a few dozen orders a month.
Shipping and delivery
Correct delivery cost at checkout, shipping label generated automatically when the order is processed, tracking link sent to the customer.
Suited when someone is currently copying addresses from your store into a carrier portal.
CRM and customer data
Leads and customers land in the CRM automatically, with their full source and context. Order history becomes visible to the sales team.
Suited when your sales team works from incomplete or out-of-date information.
| Scheduled sync | Event-based sync | Hybrid | |
|---|---|---|---|
| Suited to | large catalogues, prices, stock | orders, payments, critical changes | most stores |
| Delay | minutes or hours | instant | instant where it matters |
| Implementation effort | low | medium | medium |
| Load on the source system | controlled | low | controlled |
| Recommended for | catalogues over 1,000 products | under 1,000 products | large catalogue with frequent orders |
Our rule: We choose the hybrid approach for most projects: stock and prices sync on an interval, orders and payments sync instantly. That way your data stays correct without overloading your management software.
Reliability
An integration is judged by how it behaves when something breaks.
Servers go down, APIs have limits, data arrives incomplete. A serious integration anticipates that rather than stopping at the first exception.
A concrete example: at Maramureș Padel Club, an order placed at the table lands instantly on the kitchen screen — no paper, no manual entry.

Frequently asked questions
How is the price set?
We work on an hourly rate: €50 per hour, excluding VAT. The price comes from the number of estimated hours rather than from a fixed package. You receive a proposal in which each module carries its estimated hours and cost.
Can you integrate the management system we already use?
Yes, provided it exposes an API or a web service. We have built synchronisations between stock software and WooCommerce stores covering hundreds of products, with stock and prices updating automatically. The first step is to check what interface your software vendor provides.
What if our system has no API?
There are alternatives: scheduled file exports, direct database access where the vendor allows it, or an intermediate layer built by us. These are more fragile than a proper API, and we tell you that beforehand rather than afterwards.
How long does an integration take?
An invoicing or carrier integration takes 2–4 weeks. A full synchronisation between stock software and an online store takes 6–10 weeks. The timeline depends heavily on the quality of the data in the source system and on how quickly we receive access.
Does it synchronise both ways?
Yes, where that makes sense. Typically products, prices and stock flow from the management system to the store, while orders and customers flow back. We establish clearly which system is the source of truth for each field, so conflicts do not arise.
What happens when a sync fails?
It retries automatically. If it still does not succeed, you receive an email alert and it stays in the log with the exact reason. Workflows that fail silently are more dangerous than no integration at all.
Will the integration slow the site down?
Not if it is built correctly. High volumes are processed in batches outside user requests, and slow operations run asynchronously. We have optimised stores where issuing the invoice was blocking order completion.
Can we start with a single integration?
Yes, and we recommend it. We pick the workflow with the biggest time saving, take it to production and validate it. The second costs less, because the infrastructure and the credentials already exist.
What happens after implementation?
We stay on for monitoring. APIs change, versions update, and integrations need maintaining. We check periodically that everything runs and step in before it becomes a problem.

What would you like us to build?
You can pick more than one.
Tell us which systems you use.
You do not need to know what API each one exposes or how the connection works. Tell us which software you run and where time is lost moving data. We will check what can be integrated and reply with the estimated hours.
