Connect every systemso data is enteredonce

Versioned APIs and dependable integrations between your ERP, CRM, payment, logistics and partner systems — with explicit contracts, monitoring on every sync, and documentation your team can maintain.

Map your integrations See the results

Contract-first: Every interface versioned and documented before code is written.
Monitored: Retries, dead-letter queues and alerts — no record lost quietly.
Enterprise platforms: Odoo, SAP, Dynamics, Salesforce, HubSpot and custom systems.
2–6 weeks: From integration mapping to first live sync.

Overview

Most integrations break becausenobody owns the contract

Point-to-point scripts pile up until one small change in a partner system silently stops orders flowing, and finance discovers it at month end. We design explicit, versioned contracts between systems, treat integration as first-class engineering, and monitor every sync.

When something fails, the right person knows within minutes — with enough context to fix it. Data is entered once, flows to every system that needs it, and reconciles without a spreadsheet.

Who this is for

Enterprises running an ERP plus several satellite systems that do not agree
Companies onboarding partners, marketplaces or logistics providers via API
Platform teams exposing their own APIs to customers or internal developers

What's included

What you get from thisengagement

Working software and a documented reason for each decision — not a slide deck of possibilities.

Integration mapping
Every system, data flow, owner and failure mode documented before a line of integration code is written.
API design & development
REST and GraphQL APIs with versioning, authentication, rate limiting and documentation developers can use without asking.
ERP & CRM integration
Reliable two-way sync with Odoo, SAP, Dynamics, Salesforce and HubSpot using official APIs.
Payments, logistics & partners
Secure connections to payment gateways, carriers, marketplaces and partner APIs, with reconciliation built in.
Event-driven messaging
Queues and webhooks that keep systems in step in near real time, replacing fragile nightly batches.
Monitoring & retries
Automatic retries, dead-letter queues, audit logs and alerts routed to the person who can act.

Our approach

From mapping toproduction, in threephases

Each phase ends with something you can review and a decision point where you can stop.

Start with mapping

- Inventory of systems, data flows and current failure points
- Define system of record for each data entity
- Design the first contracts and error-handling model
- Fixed-scope plan and estimate
You end up with: An integration map, contract designs and a number — before any build starts.
- Contracts implemented and versioned first
- Integrations delivered one flow at a time, tested against real data
- Monitoring, retries and alerting live before cutover
- Documentation and runbooks written as decisions are made
You end up with: Live, monitored integrations with data reconciling across systems.
- Monitoring, incident response and partner API change management
- New flows added against the same contract model
- Periodic reconciliation and performance review
- Handover to your team when ready
You end up with: An integration layer that grows with the business instead of accumulating scripts.

Governance

Governance built intothe integration layer

Integrations move your most sensitive data. We treat them accordingly.

Authentication & authorisation
OAuth2/API keys, least-privilege scopes, secrets management.
Audit & traceability
Every record movement logged and queryable.
Data protection
Encryption in transit, field-level handling of personal data, retention rules.
Change control
Versioned contracts and deprecation policy so partner changes never surprise you.

Why us

Why partner with Kaidova on integration

Our own platforms integrate with the ERPs, payment providers and carriers our customers use. The discipline that keeps those syncs healthy is the one we bring to yours.

Contract before code
Interfaces are designed, versioned and agreed before implementation — so changes are managed, not discovered.
Nothing fails silently
Every sync is monitored with retries and alerts; failures reach the right person within minutes.
A number before you commit
Mapping ends with a fixed estimate and a measurable target for the first live flow.
You own everything
Code, contracts and documentation are yours, with no proprietary middleware to keep licensing.
Built to be handed over
Runbooks and decision records let your team operate and extend the layer without us.
