# Integration & consulting

> Technology consulting, APIs, system integration, maintenance, technical support and training that help your people and systems work together.

## Connected systems. Clearer decisions.

Make the tools you already use work together. We help map technical decisions, connect APIs and turn fragmented processes into understandable workflows.

## Fit

For teams dealing with duplicate data entry, disconnected applications or a technology decision that needs a practical plan.

## Scope

- **Technology consulting:** Assess requirements and trade-offs, with a practical roadmap shaped by the existing environment and team.
- **APIs & system integration:** Connect applications through documented interfaces, with clear data ownership and error handling.
- **Workflow & data mapping:** Define how information moves, where validation belongs and what should happen when a dependency fails.
- **Handover & training:** Documentation, technical support and training that help the people responsible for a system operate it.

## Process

1. **Understand the whole flow:** Identify stakeholders, applications, data owners and the points where work gets stuck.
2. **Connect with clear contracts:** Define mappings, interfaces and failure behavior before implementing and validating the integration.
3. **Transfer the knowledge:** Document decisions and operating tasks so the team can manage the connected workflow.

## Examples

### Connected operations

- Challenge: Sales and operations teams re-enter the same customer and order information.
- Approach: Agree the source of truth, map fields and connect the systems with validation, retries and exception visibility.
- Deliverable: An integration workflow with field mappings, failure handling and operational documentation.

### A technology roadmap

- Challenge: Several competing tools or approaches could solve the problem, but the trade-offs are unclear.
- Approach: Review users, constraints and the existing stack, then compare options against explicit decision criteria.
- Deliverable: A technical recommendation, dependency map and prioritized implementation plan.

### A system handover

- Challenge: A useful system depends on knowledge held by one person or an external team.
- Approach: Trace critical workflows, document operating steps and work through practical training with the team.
- Deliverable: Runbooks, architecture notes and a structured handover of the agreed workflows.

## FAQ

### Can you connect software we already use?

That depends on each system’s API, permissions and export options. Discovery checks those capabilities before committing to an integration approach.

### Can we start with consulting only?

Yes. A scoped review or roadmap can be a standalone engagement, with implementation considered after the findings are understood.

### Who owns the data between systems?

The integration design should explicitly identify the authoritative source for each record, access rules and how conflicts are resolved. These decisions are agreed with your team.

## Reference architecture
A reference integration flow. Mapping data is only part of the work; failures and conflicting updates need a deliberate resolution path.
### Source
ERP, CRM or API → Identifiers & ownership
Read approved records from the system that owns each entity and field.
Review: Confirm API access, identifiers, rate limits, change events and source-of-truth rules.
### Exchange
Validation & mapping → Queues & safe retries
Translate records into the destination contract and handle temporary failures without duplicating work.
Review: Check malformed records, partial writes, duplicate events and version changes.
### Destination
Accepted records → Reconciliation & exceptions
Make accepted records visible and give operations teams a way to resolve missing or inconsistent updates.
Review: Compare counts and totals, trace failed records and agree who resolves each exception.
Illustrative planning model; scope and deliverables are agreed per project.

## Technology choices
Connect through explicit contracts
### Interfaces
APIs · Webhooks · File exchange
Choose an interface after reviewing the systems’ supported contracts, rate limits and access methods.
### Processing
Node.js · TypeScript · Validation
Define entity identifiers, mappings and validation rules that preserve source-of-truth ownership.
### Operations
Queues · Retry rules · Reconciliation
Choose delivery and exception-handling patterns based on update timing and the consequences of partial failure.
## Quality checks before handover
### Correct mapping
Compare representative records and edge cases, including units, missing fields and changed identifiers.
### Safe recovery
Test duplicate events, partial writes and unavailable destinations against agreed retry behavior.
### Visible exceptions
Verify that failed or inconsistent records can be traced, assigned and reconciled by operations teams.
