Acumatica customisation for VARs. We ship scoped packages that cut unused SaaS, finish implementations that overran, and wire AI into the ERP the customer already runs — without sending their data to train anyone else's models.
Open-source libraries are how we show the work. Each public repo is installable.
| Repo | What it is | Install |
|---|---|---|
| AISI.AcumaticaWebhookAuthenticator | HMAC / Basic / shared-secret auth for IWebhookHandler, with secrets in the ERP |
GitHub Release zip + nupkg |
Coming next, same quality bar: Attachment Trace (which record is this file on?), in-process MCP (AI tools inside the customer's IIS process — no second host).
Nothing here is a placeholder. If it is public, you can import it.
Stack-cut integrations. Acumatica's unlimited-user model and open API have no per-integration licence fee. We retire overlapping SaaS and authenticate the webhooks properly.
VAR overflow and rescue. Fixed-time or capped time-and-materials customisation: configuration, DACs/graphs/workflows, data migration, Modern UI, tests, documentation. The work VARs already hand off when a prior team went over budget.
In-system AI, with a written policy. MCP and automations that run against the ERP the customer already has.
Acumatica 2025 R2 – 2026 R1. Classic UI is gone in 2026 R2; new work is Modern UI first.
Public repositories are MIT unless a repo says otherwise. Licensed PX.* assemblies are never redistributed.
