KTree

ServicesAI and integrations

We connect your ERP, store, payment, shipping and messaging systems, so data is entered once.

For businesses where staff copy orders, stock and customer records from one system to another by hand. We build the links between your systems, watch them, and can open the same links to AI assistants. An API is a defined way for one program to ask another for data or an action.

What you get

What we hand over

  1. 01

    The integration, working in both directions

    Records move between your systems by themselves: orders, invoices, stock, customers, shipments and payments. We have connected SAP, Microsoft Navision and Odoo to web applications and online stores, stores to marketplaces and carriers, and applications to payment providers and banks.

  2. 02

    An API for your own system

    When your application has no API, we build one, in REST or GraphQL, with a login and written documentation, so partners, mobile apps and other systems can use it. An API gateway, a single front door that checks each request, sits in front where several systems call in.

  3. 03

    Logs, alerts and retries

    Every record that moves is logged. A failed record is retried, and if it still fails the right person gets an email. A status page shows which jobs ran, what they moved and what went wrong.

  4. 04

    An MCP server for AI assistants

    MCP (Model Context Protocol) is an open standard for connecting AI models to business systems. An MCP server placed in front of your APIs lets an AI assistant or agent read and write records with the permissions you set, so the same integrations serve your staff and your AI tools.

How it works

Each record moves by itself, and every failure is seen

An integration is simple on a good day. The work is in the bad days: a system that is offline, a record that arrives twice, a field that does not match. We design for those first.

  1. 1We agree which system owns each piece of data, then choose how it moves. A scheduled job copies changes every few minutes or every night. A webhook is a message one system sends to another the moment something happens, for example a delivery report from an SMS provider.
  2. 2Where volumes are high, a queue sits between the systems. The sender drops each record in the queue and carries on, and the receiver takes them at its own pace, so a slow or offline system does not block the other.
  3. 3Records that were missed are filled in afterwards. For a US vehicle parts company, automated jobs reload the orders that did not arrive when a connection dropped.
  4. 4When one route fails, another is tried. In a messaging platform we built for an airline, messages are spread across several SMS providers, a provider with poor delivery is suspended automatically, and the message goes out by WhatsApp, Telegram or Viber instead.

Your options

Your options, compared honestly

  • Alternative

    Staff as the link

    Retyping, or exporting and importing spreadsheets, needs no project and works at low volume. As orders grow it costs hours every day, and typing mistakes reach customers and accounts.

  • Alternative

    A ready-made connector

    Many products sell a plugin that links two well-known systems, and when it covers your case it is the cheapest and fastest route. It stops fitting when your process has its own rules, fields or approval steps.

  • Alternative

    A no-code automation tool

    Good for simple, low-volume links between popular online services, and business staff can set it up. It gets hard with large volumes, systems inside your own network, or errors that have to be traced record by record.

Before you ask

Questions about API integrations

Short, straight answers. Anything else, ask in the form below and an engineer will reply.

Which systems have you connected?

ERPs such as SAP, Microsoft Navision and Odoo. Online stores and marketplaces such as Magento, WooCommerce and Amazon. Carriers such as FedEx, DHL and bpost, payment providers such as Adyen, PayPal and Stripe, and SMS and WhatsApp services. We have also linked CRMs to phone systems, hospital applications to medical record systems, and a trading screen to a market data feed.

Our old system has no API. Can it still be integrated?

Usually, yes. Data can be exchanged as files on a schedule, read from the database, or passed through a small API that we add in front of the system. We have loaded supplier files collected over FTP and read attendance records from a biometric device database in this way.

What happens when one of the systems is down?

Nothing is lost. Records wait in a queue or are marked as not yet sent, and they go through when the system is back. The failure is logged and an alert is sent, so somebody knows before a customer does.

Can AI assistants use these integrations?

Yes. We put an MCP (Model Context Protocol) server in front of the APIs, so AI agents can read and write records with the permissions you set. A person still approves what the AI prepares before anything important is posted.

How do you price an integration?

A fixed price when the scope is clear: which systems, which records and in which direction. A monthly rate for a dedicated team suits a long list of integrations. Every estimate is written down with what is included.
