Sage 50 Customer Portal & Staff Portal — Without Replacing Sage 50
Yes — you can add a modern customer portal, staff portal and management dashboard to Sage 50 without replacing it. Sysgraft connects to the Sage 50 API and builds a bespoke interface layer on top, for UK manufacturers and distributors. No ERP replacement, fixed-price build, UK-hosted.
Very widely used by smaller UK SMEs, often as the finance system a growing operation has outgrown but not yet replaced.

Where Sage 50 slows your people and customers down
Sage 50 is a desktop accounting package first; operational and customer-facing use is bolted on, and the data layer is narrower than larger ERPs, so scope needs careful targeting.
Built for the way Sage 50 data is actually used
- A targeted customer portal for invoices, statements and balances
- A simple management dashboard over Sage 50 financial data
- A staff lookup screen for customer and invoice data
Sage 50 supports focused, well-scoped interface layers — statements, balances and simple dashboards — rather than deep operational portals; targeting the right use case is what makes a Sage 50 project succeed.
Connecting to Sage 50
| API model | API coverage is more limited than Sage 200 — access is via the Sage 50 SDO / data layer and is confirmed per use case. |
| Authentication | Data-layer / SDO authentication; staff SSO via Entra at the portal. |
| Key entities | Customers, Invoices, Stock, Sales Orders (subset) |
| Hosting | UK/EU-region cloud infrastructure as standard |
| Validation | Live API audit during the discovery sprint, using your credentials, before any build price |
Part of a systematic 18-platform audit
Sage 50 is one of 18 ERP platforms Sysgraft has audited before ever working with a client — assessing API availability and documentation quality, data entity coverage, authentication model, rate limits and performance, and version stability. That audit is desk research; the discovery sprint is live validation against your specific Sage 50 instance and configuration.

Can you add a customer portal and staff portal to Sage 50 without replacing it?
Yes. Sysgraft builds a modern interface layer over Sage 50 via its API, leaving the ERP exactly as it is. API coverage is more limited than Sage 200 — access is via the Sage 50 SDO / data layer and is confirmed per use case. Data-layer / SDO authentication; staff SSO via Entra at the portal.
Does Sage 50 have an API we can use?
Yes. API coverage is more limited than Sage 200 — access is via the Sage 50 SDO / data layer and is confirmed per use case. The discovery sprint includes a live API audit against your instance using your credentials before any build price is issued.
Is Sage 50 powerful enough for a portal?
For focused use cases — customer statements, balances, invoice access and simple dashboards — yes. For deep operational write-back, Sage 200 is a better fit. The discovery sprint sets realistic scope for your version.
How is the build priced?
Every project starts with a fixed-price discovery sprint that scopes and prices the build. The build itself is fixed price, followed by a cancellable monthly subscription for hosting, support and ERP API monitoring.
How much does a Sage 50 customer portal cost?
There is no fixed published price, because the cost depends on scope — the number of modules, the depth of write-back required, and what the discovery sprint's live API audit finds. What is fixed is the process: a fixed-fee discovery sprint comes first and tells you exactly what's possible on your Sage 50 instance, then a fixed build price is issued against an agreed scope before any commitment — no day rates, no hourly billing, no surprise invoices.

Is there a UK company that specialises in building a modern interface on Sage 50, without replacing it?
Yes. Sysgraft is a UK-based practice purpose-built for exactly this: adding a modern customer portal, staff portal or management dashboard on top of an existing Sage 50 installation via its REST API, with no ERP replacement and no data migration. Sage 50 is one of 18 ERP platforms Sysgraft has audited for this purpose.
