18 ERP platforms audited. We almost certainly work with yours.
Sysgraft has audited the REST APIs of 18 ERP platforms used by UK manufacturing and wholesale distribution SMEs. For each one we have mapped what a modern customer portal, staff portal and management dashboard can realistically do -- and where the API sets limits. If your ERP is on this list, we can connect to it. If it is not, ask us: if it exposes a REST API, the answer is almost certainly yes.
Before launching Sysgraft, we conducted a systematic audit of the 18 ERP platforms most commonly used by UK manufacturing and wholesale distribution SMEs across five dimensions: API availability and documentation quality, data entity coverage, authentication model, rate limits and performance, and version stability. The result: a clear picture of what is possible on each platform, and confidence that the discovery sprint will never hit a surprise.
Primary launch platforms
Excellent public REST API, highest UK SME installed base, proven integration capability. Full build confidence.
Strong secondary platforms
Good API coverage, significant UK market presence, API validated in discovery sprint before build scoping.
Audited platforms
Audited for API capability. Discovery sprint confirms exact scope. Most have sufficient API coverage for the core use cases.
Tier 1 — Primary Platform
Highest confidence. Proven API. Largest UK installed base.
The most commonly deployed ERP in UK manufacturing and distribution SMEs. Highest API score in our audit. Staff operations portals, customer self-service portals, and management dashboards are all well within API coverage.

Tier 2 — Strong Secondary Platforms
Good API coverage. Significant UK presence. API validated during discovery sprint.
One of the most widely deployed ERP systems in UK manufacturing SMEs. Strong installed base, particularly in the Midlands and North. Well-suited to customer portal and operations dashboard use cases.
A KCS (Kerridge Commercial Systems) product, dominant in UK wholesale distribution. Strong use cases for trade ordering portals, customer self-service, and stock visibility dashboards.
Read: OrderWise BottlenecksAlso a KCS product, K8 dominates the UK builders merchants and specialist distribution sectors. Trade counter portals and customer account access are the primary use cases. A single KCS partner relationship unlocks both K8 and OrderWise markets.
Strong API with comprehensive coverage. Used widely in UK manufacturing mid-market. Interface layers for operations and customer portals are well-supported. API terms reviewed as part of discovery sprint.
Tier 3 — Audited Platforms
All audited. Most have sufficient API coverage. Discovery sprint confirms exact scope for your version and configuration.
Widely used in UK discrete manufacturing. Strong API for production-oriented interfaces including shop floor dashboards and work order tracking.
Strong manufacturing depth with good API coverage. Interface layers for operations, stock, and customer-facing use cases are supported.
Cloud-native ERP with strong API. Well-suited to customer portal and management dashboard use cases. Growing UK presence in distribution and services.
Enterprise-grade API with good coverage for manufacturing and service-oriented use cases. Interface layers for field service and production visibility are strong candidates.
API integration via Infor ION. Good coverage for manufacturing entities. Particularly relevant for discrete and process manufacturing SMEs.
UK-developed ERP with a reasonable API footprint. Customer portal and management dashboard use cases are achievable. Discovery sprint confirms entity coverage for your configuration.
Long-established UK ERP. API coverage depends on version and configuration. Discovery sprint confirms feasibility before any build commitment.
Growing UK presence in manufacturing and distribution. Good REST API with solid entity coverage for the core interface layer use cases.
Cloud-native with a clean REST API. Growing UK distribution presence. Good candidate for customer portal and operational interface use cases.
Microsoft's enterprise-tier ERP. Stronger API than Business Central in some areas. Typically deployed in larger manufacturing businesses. Same Microsoft Entra SSO model as Business Central.
Strong in UK and Irish wholesale distribution. Customer portal and order management interface are well-suited use cases. Solid API coverage confirmed in audit.
Cloud-based ERP strong in omnichannel distribution. Good REST API. Customer-facing portal and order visibility interfaces are achievable use cases.
Widely used UK accounting and ERP system. API scope more limited than Sage 200 but sufficient for targeted use cases. Discovery sprint confirms what is feasible for your configuration.

Don't see your ERP?
The 18 platforms above cover the vast majority of UK manufacturing and distribution SMEs. But there are hundreds of ERP systems in use across the UK market.
If your ERP has a REST API — and most modern systems do, even if you've never used it — we can almost certainly work with it. The discovery sprint includes a live API audit using your credentials. That audit tells us what's possible on your specific system before any build commitment is made.
Running something not on this list? Get in touch and we'll tell you within 24 hours whether we can work with it.
Book a Discovery CallWhat the ERP audit actually means
Saying "we work with 18 ERPs" is meaningless without explaining what that means in practice. Here is what our audit established for each platform — and what happens in your discovery sprint.
Does the platform expose a REST API? Is it documented? Is the documentation public or partner-gated?
Which business entities are available — orders, stock, customers, invoices, production, despatch? Read and write, or read-only?
OAuth 2.0, API key, basic auth? Can it support Microsoft Entra SSO for staff? What does customer authentication look like?
Can the API support real-time queries at the frequency a production application needs? Are there throttling or licensing constraints?
How frequently does the API change? Is there a versioning policy? What is the deprecation notice period?
What the discovery sprint adds
The audit above is desk research. The discovery sprint is live validation against your specific system, version, and configuration using your actual credentials.
- Live authentication test against your ERP instance
- Retrieve and inspect real data from your key entities
- Test write-back on entities that require it
- Document any gaps and confirm workarounds or alternatives
- Fixed-price build proposal only issued after this is complete
The guarantee behind this
We never issue a fixed-price build proposal without a completed discovery sprint. If the API turns out to be insufficient for your use case, we tell you at discovery stage — not mid-build. That is the protection the discovery sprint provides.
Pick your ERP for the detail
Each platform has its own page covering the customer portal, staff portal, integration model and UI modernisation specific to that system.
