System Integration Services in South Africa
Most operational pain in growing South African businesses is a connection problem, not a software problem. Salesforce doesn't talk to your ERP. Your custom platform doesn't sync with finance. Quotes are re-keyed into invoicing. Reports come from three exports stitched in Excel. We fix that. As system integration consultants and API integration developers we design the contracts between your systems, build the integrations and run them in production — so data flows once, cleanly, with proper error handling.
- Salesforce, ERP and SaaS integrations — connect your CRM, finance and operations systems
- Custom API development — REST, GraphQL and webhook APIs for products and partners
- Production discipline — auth, retries, idempotency, monitoring, audit logs
- Built on Python, Django and FastAPI by senior engineers
We are an API integration developer in South Africa — engaged for custom API development in Cape Town, Johannesburg, Durban and across the country. Delivery is remote-first; we align on POPIA, data residency and your internal change processes regardless of where you are based.
We also support clients outside South Africa when the fit is right — the same integration discipline, with contracts, SLAs and meeting cadence scoped per engagement.
Not sure if this is the right page?
- This page (System integration & APIs): you have multiple systems that need to talk to each other, or you're exposing data to partners and product features and need an API designed and built properly.
- Custom software: you need a new application or platform built — integrations are usually scoped within that engagement.
- Automation: you need a specific manual workflow automated end-to-end, often touching one or two systems.
- Data analytics: you need data out of systems into dashboards and reporting, not bidirectional sync.

What We Build
Specific deliverables, scoped per system pair. From connecting Salesforce to custom software to ERP-finance bridges and partner-facing APIs — we design the contract, build the integration and operate it.
Salesforce Integration
Connect Salesforce to custom software, internal tools, billing platforms or your website. Two-way sync of accounts, contacts, opportunities and custom objects — with proper field mapping, conflict resolution and audit logs.
ERP Integration
As ERP integration developers we connect SAP, Syspro, Sage, Acumatica and Microsoft Dynamics to web apps, e-commerce platforms, CRM and bespoke software. Inventory, orders, invoices and master data flowing reliably between systems.
Custom API Development
Custom API development in Cape Town for products and partners. REST and GraphQL APIs designed for stability — versioning, authentication, rate limiting, pagination and clear documentation engineers can actually use.
Webhooks & Event Systems
Event-driven integrations with retries, signed payloads, dead-letter queues and replay. Stripe-style webhooks for your platform, or consumers for third-party events. We treat webhook delivery as a contract, not a fire-and-forget HTTP call.
Finance & Accounting Sync
Integrate Xero, QuickBooks, Sage and Syspro with your CRM, billing or operations stack. Invoices, payments, customers and chart of accounts kept in sync — with month-end resilience. See accounting automation for the full picture.
Legacy System Bridging
Older systems with no modern API — SOAP services, flat-file exports, SQL-only access, on-prem databases. We wrap them in clean REST APIs so the rest of your stack can move faster without ripping out what works.
Production Integration Engineering
Most integrations break the same way: silent failures, partial syncs, duplicate records, no audit trail when finance asks why a number is wrong. Below is how we engineer integrations and APIs so they stay reliable — distinct from single-workflow automation and from application builds.
API design
The contract is the product.
- Resource modelling: URLs, verbs and status codes that match how clients actually consume the data.
- Versioning: URL or header versioning, deprecation windows and changelogs so partners aren't surprised.
- Pagination, filtering, sorting: consistent across endpoints — not invented per resource.
- Errors: structured error bodies with codes, messages and request IDs you can trace.
- Docs: OpenAPI / GraphQL schemas plus written guides — not auto-generated walls of text.
Auth & security
Keys are not enough.
- OAuth 2.0, JWT, API keys: the right choice per integration — partner, server-to-server or user-delegated.
- Scopes & tenancy: least-privilege access, multi-tenant isolation, per-customer key rotation.
- Rate limiting: per-key and per-IP, with backoff guidance in headers — not just 429s with no plan.
- Secrets & logs: credentials in vaults, never in client bundles or repos; logs redacted; data residency aligned with POPIA.
Data sync patterns
Where most integrations actually fail.
- One-way vs two-way: we resist two-way sync unless you genuinely need it — it's where conflicts and corruption hide.
- Idempotency: safe retries via idempotency keys so a flaky network doesn't create duplicate orders or invoices.
- Conflict resolution: explicit rules — last-write-wins, source-of-truth per field, or human review for ambiguous cases.
- Backfills & replays: the ability to reload historical data without breaking what's live.
- Audit trail: every sync event logged with source, target, payload hash and outcome — finance and compliance can answer "why".
Monitoring & ops
Integrations fail quietly without this.
- Health checks: per-integration uptime, latency and error rate dashboards — not just "the server is up".
- Alerts: when sync lag exceeds thresholds, or third-party APIs deprecate endpoints, or rate limits get hit.
- Dead-letter queues: failed messages held for inspection and replay, not lost.
- Runbooks: documented playbooks for the failures that actually happen — not theoretical incidents.

Industries We Integrate For
Integration patterns differ by sector. Compliance, data volumes and the systems already in place all change the design. We've built across these.
Financial Services
Connecting CRM, core banking, KYC providers and finance systems. Audit-ready integrations with reconciliation built in. POPIA, data residency and segregation handled by design.
E-commerce & Retail
Shopify, WooCommerce and bespoke storefronts integrated with ERP, warehouse, courier and payment systems. Inventory and order data correct end-to-end.
Manufacturing & Logistics
ERP-to-ops integrations: MRP, dispatch, telematics and customer portals. Master data and orders flowing without spreadsheet exports.
SaaS & Technology
Public APIs and partner integrations for your product. Webhooks, OAuth flows, SDKs and developer documentation that helps customers self-serve.
Healthcare
Practice management, scheduling, billing and reporting systems integrated with patient-facing portals. Privacy and consent handling baked into the data flow.
Professional Services
Salesforce, HubSpot, Xero, Sage and bespoke time-tracking glued together so projects, billing and reporting stay aligned without manual reconciliation.
How We Deliver Integrations
A repeatable process — from discovery to production deployment and ongoing operation. As system integration consultants we want to ship something that runs and doesn't generate calls at month-end.
Discover & Map
Walk through every system, data flow and edge case. Identify the source of truth per field and where conflicts will arise.
Design
API contracts, sync patterns, auth model and failure modes — agreed before code. You see the shape before we build it.
Build & Test
Engineered with retries, idempotency and audit logs from day one. Tested against staging systems and replay scenarios — not just happy path.
Deploy & Operate
Phased rollout, monitoring, alerts and runbooks. We support post-launch — most integrations need a tune in the first 30 days.
Integration Patterns We've Shipped
CRM ↔ Custom Platform
Salesforce two-way sync with a bespoke operations platform — accounts, opportunities and custom objects. Field-level conflict rules and an audit log finance can query at month-end.
ERP ↔ Web App
Connecting Syspro and Sage to a customer-facing portal. Inventory, orders and invoices synced with idempotent writes — no duplicates, no missing orders, even when the ERP is down.
Finance Sync
Automated bank statement processing feeding Xero and Sage. 200+ statements a month reconciled with full traceability.

Frequently Asked Questions
Are you a system integration consultant or a development agency?
Both. We scope and design the integration architecture and we build it. Many system integration consultants stop at diagrams; we hand over running code, monitoring and runbooks. If you only need advice, that's fine — we'll be transparent about scope.
Can you connect Salesforce to our custom software?
Yes. We connect Salesforce to custom software regularly — using the Salesforce REST and Bulk APIs, with proper field mapping, conflict resolution and audit logging. We handle one-way reads, two-way sync and event-driven updates depending on what your team actually needs.
Which ERP systems do you integrate with?
We've worked with SAP, Syspro, Sage, Acumatica, Microsoft Dynamics and several legacy on-prem systems. Most ERP integration developer work involves a mix — modern REST APIs for newer modules and SOAP, flat-file or direct database access for older ones. We design the bridge accordingly.
How long does a typical integration project take?
A focused one-way integration between two well-documented APIs is usually 2–4 weeks. A two-way sync with conflict resolution and audit logging takes 6–10 weeks. Legacy ERP integration often runs 8–12 weeks because access and discovery take longer. We'll give you a clear timeline after the discovery phase.
Should we use Zapier or Make instead of custom integration?
Sometimes — and we'll tell you when. iPaaS tools are excellent for low-volume, low-stakes glue between SaaS apps. They struggle with high volume, complex data shapes, two-way sync, custom auth and audit requirements. If you're already pushing your iPaaS into corner cases, that's usually when custom API development pays off.
Can you build an API for our product so partners can integrate with us?
Yes — that's a large part of what we do. We design partner-facing REST and GraphQL APIs with proper auth, rate limiting, versioning and developer documentation. The goal is partner engineers being able to integrate without needing your team's help.
