Where Acumatica slows your people and customers down
Acumatica's generic web UI works but is not branded or role-optimised for your specific customers and staff; high-frequency tasks and customer self-service benefit from a tailored layer.
Built for the way Acumatica data is actually used
- A branded customer self-service portal
- A staff portal for order and inventory operations
- A KPI dashboard tuned to your business
Acumatica's contract-based REST API is one of the cleanest in the market, so interface layers are low-risk and version-stable to build and maintain.
Connecting to Acumatica
| API model | A well-documented contract-based REST API gives clean, version-stable access to orders, inventory, customers and more. |
| Authentication | OAuth 2.0; staff SSO via Entra at the portal. |
| Key entities | Sales Orders, Inventory, Customers, Invoices, Shipments |
| 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
Acumatica 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 Acumatica instance and configuration.

Can you add a customer portal and staff portal to Acumatica without replacing it?
Yes. Sysgraft builds a modern interface layer over Acumatica via its API, leaving the ERP exactly as it is. A well-documented contract-based REST API gives clean, version-stable access to orders, inventory, customers and more. OAuth 2.0; staff SSO via Entra at the portal.
Does Acumatica have an API we can use?
Yes. A well-documented contract-based REST API gives clean, version-stable access to orders, inventory, customers and more. The discovery sprint includes a live API audit against your instance using your credentials before any build price is issued.
What is a contract-based API and why does it help?
Acumatica versions its API as named contracts, so endpoints stay stable across upgrades. That makes the interface layer easier to maintain and less likely to break on an ERP update.
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 Acumatica 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 Acumatica instance, then a fixed build price is issued against an agreed scope before any commitment — no day rates, no hourly billing, no surprise invoices. See how Sysgraft pricing works for the full model.
Is there a UK company that specialises in building a modern interface on Acumatica, 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 Acumatica installation via its REST API, with no ERP replacement and no data migration. Acumatica is one of 18 ERP platforms Sysgraft has audited for this purpose.
