Systems integration

Make your systems talk and your operation flow.

ERPs, CRMs, banks, gateways, WhatsApp, email, calendars, payments and operations tools — connected in end-to-end automated flows that survive real volume.

Challenges we solve

When the process stalls, the business stops.

Data entered twice or three times

The same information keyed into different systems every day, generating drift and rework.

Manual reconciliation errors

Bank statements, orders, invoicing and inventory reconciled by hand, with hidden losses.

Critical systems that don't talk

Core platforms disconnected from the ERP or CRM, forcing spreadsheets as glue.

Amateur automations that break silently

Scripts, macros and spreadsheet automations that fail without alerting anyone.

New integrations treated as projects

Every new connector demanding budget, committee and risk analysis — instead of being routine.

Overview

A platform modelled around your business.

We design reliable integrations between your systems, with queues, retries, logs and observability. We combine in-house code with platforms like n8n and Make when it fits — delivering flows that hold up under real volume, not demo conditions.

Royal Infinite differentiators
  • Integrations that survive real operational volume
  • End-to-end observability and alerting
  • Pragmatic mix of n8n/Make and in-house code
  • Measurable reduction of rework and errors
Core capabilities

End-to-end capabilities.

APIs & webhooks

Publishing and consuming REST, GraphQL and webhook contracts with versioning.

Legacy ERP integration

Connecting to SAP, TOTVS, Sankhya, Oracle and custom systems, with or without an official API.

Banking & payments

PIX, boletos, cards, acquirers, gateways and reconciliation.

WhatsApp & email

WhatsApp Business API, transactional email and auditable templates.

Calendars & scheduling

Google, Microsoft and custom scheduling platforms.

Marketplaces

Mercado Livre, Amazon, Shopee, B2W and logistics integrators.

Documents

E-signature, invoices, contracts and corporate drives.

Automation orchestration

n8n/Make or in-house engine with monitoring and alerts.

Implementation flow

From discovery to go-live.

1

Discovery

Mapping systems, flows and friction points across the operation.

2

Architecture

Contracts, queues, retries, idempotency and observability by design.

3

Engineering

Building with automated tests and separate environments, delivering flows incrementally.

4

Evolution

SLA-backed operation, contract evolution and new flows as the ecosystem grows.

Integrations & architecture

Engineered to connect.

  • Queues and workers for volume and resilience
  • Idempotency and controlled retries
  • Observability with logs, metrics and alerts
  • Separate dev, staging and production environments
  • Versioned contracts and automated tests
  • Fine-grained secrets management

Use cases

Built for real operational scenarios.

Order to cash across systems

Marketplace or B2B order flowing to ERP, tax, logistics and finance without human keystrokes.

Bank reconciliation on autopilot

Statements, PIX and gateway settlements matched to invoices in near real time.

Customer messaging in one channel

Sales, service and post-sale conversations unified in WhatsApp and email, logged in the CRM.

Legacy modernisation

Wrapping monoliths with APIs so new products can be built next to them without a full rewrite.

Partner ecosystems

Onboarding suppliers, franchisees and marketplaces through governed, versioned integrations.

Cross-system reporting

Piping transactional data from every operational system into the analytics stack.

Business outcomes

Value that compounds with the operation.

Rework eliminated

Data flows automatically between systems, freeing people from mechanical typing.

Fewer costly errors

Every integration has validation, retries and observability — mistakes surface early, not at month-end.

Operation ready to scale

New products, channels and partners plug into existing flows instead of triggering new projects.

Independence from vendors

You own the integration layer — swapping tools no longer means rebuilding everything.

Continuous visibility

Every flow has metrics, logs and alerts — you know when something breaks before customers do.

Frequently asked questions

Integrations & automation

If you still have a question, talk to our team — we respond quickly.

  • It depends on the flow. Light flows work well on n8n/Make; critical flows earn in-house code with queues, tests and observability.
