Frequently asked questions
Sage Intacct Construction scores D+ on Supergood's API Report Card. Sage Intacct Construction rides the standard Intacct APIs: modern REST with OAuth 2.0 plus the legacy XML API, where all 18 construction objects (retainage, change orders, rate tables) live today. Sender credentials and per-customer Web Services authorization make onboarding manual.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.

Performance-tier transaction caps, default Tier 1 allows only 100,000 API transactions/month, with overage billed in packs of 10 (~$0.15/pack on Tier 1); upgrading requires going through a CSM. Every create/update/delete/query counts as a transaction; batched creates don't share a transaction, making bulk loads expensive against the cap. Full sourced list under Sources below.
Common alternatives include Trimble Viewpoint (Vista / Spectrum), Foundation Software, Acumatica Construction Edition, Oracle NetSuite (Construction), CMiC, Procore (Financials / Pay). Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Sage Intacct Construction has partial MCP support. There is no official or construction-specific MCP server. Community MCP servers for Sage Intacct wrap the same Intacct API that Intacct Construction runs on, so they can reach its data, but nothing is vendor-backed.
Partially. MCP support for Sage Intacct Construction exists but is incomplete, so what MCP clients like Claude, Cursor, and Codex can reach depends on what the available server covers.
