In Claude: Customize → Connectors → + Add → Add custom connector. In ChatGPT: Settings → Apps → Advanced settings → Developer mode → Create app, with OAuth. In Codex: `codex mcp add stacksync --url https://mcp.stacksync.com/mcp` then `codex mcp login stacksync`. Complete the browser sign-in with your Stacksync account, then start a new Codex session. In Claude Code: `claude mcp add --transport http stacksync https://mcp.stacksync.com/mcp`. Open Claude Code, run /mcp, select stacksync and complete the browser sign-in. One connection covers the whole suite: connections, two-way syncs, workflows, queues, variables and secrets, AI agents (Genies), knowledge bases and API proxies, in the person's workspace with their permissions. Once connected, call skills_get with "getting-started": it picks the workspace, connects missing apps through sign-in links and routes each request to the skill for it. Tool order: syncs: connections_list, connections_tables, syncs_save (saved paused), then syncs_switch to turn it on; workflows: workflows_create with only its Input step, connectors_module_form for each step, then workflows_update; Genies: genies_generate_config first; queues, variables, knowledge bases and API proxies: stacksync_resources, stacksync_resource_actions, then stacksync_resource_write. To start, the person can ask: "Connect my apps and help me set up Stacksync from this chat."

Author Ruben Burdin · Founder & CEO Published September 18, 2026 Read time 4 min read DATA ENGINEERING ## The operating decision HubSpot–Acumatica integration works best when sales context and accounting truth have clear responsibilities. HubSpot can carry the relationship, opportunity, and customer-facing project summary; Acumatica remains the owner of project accounting and released billing information. Use external identifiers to join companies, customers, and projects, then expose the status sales needs. Validate the Acumatica entities, endpoint fields, and allowed operations in your environment before treating a proposed mapping as an available write. Explore the complete [construction services and installation integration and automation hub](https://www.stacksync.com/industry/construction) for the systems and processes around this guide. ![Summary card: HubSpot Acumatica sync for construction projects and billing](https://www.stacksync.com/images/blog-highlights/icp-hubspot-acumatica-for-construction-services-customers-projects-and-invoice-status.webp) ## What this looks like in construction services and installation A commercial installation business sells repeat projects to a property group. Sales tracks an opportunity in HubSpot, while finance creates an Acumatica customer and separate projects for each facility. A project manager later approves a scope change. The account team needs to see the correct project and billing status without copying financial values into a free-text deal note. The integration must distinguish the original opportunity from later approved project revisions. ## Records, ownership, and update rules | Record | Owner | Operating rule | | --- | --- | --- | | HubSpot company | Sales operations | Store the Acumatica customer reference without replacing HubSpot's native record ID. | | Acumatica customer | Finance | Own legal name, billing address and approved payment terms. | | Project association | Project administration | Connect the deal to the approved project key, including branch or company context. | | Invoice summary | Accounts receivable | Publish released status and reference; treat collection notes as a separate field. | ![Record ownership diagram: HubSpot company, Acumatica customer, Project association](https://www.stacksync.com/images/blog-diagrams/icp-hubspot-acumatica-for-construction-services-customers-projects-and-invoice-status.webp) *Define the record owner and the rule before enabling updates.* ## Work through the process 1. 01 Define the commercial-to-project boundary Choose the event that makes a deal eligible for project setup. Closed-won alone may not mean the customer passed finance review or signed the final scope. Capture those prerequisites explicitly and agree whether the first integration release proposes a project setup task or performs a verified record operation. 2. 02 Map company and contact roles A property manager may be the sales contact while another legal entity pays the invoice. Map the contact's role alongside the customer relationship instead of making the first associated company the automatic bill-to. Keep branch-specific addresses and project contacts available without changing the legal customer master. 3. 03 Confirm entity access Inspect the actual Acumatica endpoint and role permissions for the entities you intend to read or update. The existence of projects and construction features does not establish every connector action. On HubSpot, verify object availability and the account tier before choosing custom objects for sites or project summaries. 4. 04 Return useful billing context Send invoice reference, released status, balance context where approved, and the finance-owned update time to a dedicated customer-facing summary. Keep draft billing separate from released invoices. If several invoices belong to one project, preserve their individual references rather than replacing the deal amount with the latest invoice amount. 5. 05 Reconcile revisions and associations Test a customer merge, a project reassignment, and an invoice that is corrected after release. Confirm that the relationship is updated without creating a duplicate project. Because associations can arrive separately from ordinary records, the account team should see an explicit pending state until the related customer and project are joined. ![5-step operating sequence: HubSpot Acumatica sync for construction projects and billing](https://www.stacksync.com/images/blog-diagrams-mermaid/icp-hubspot-acumatica-for-construction-services-customers-projects-and-invoice-status.webp) *Follow the operating sequence; unresolved exceptions return to a responsible reviewer.* ## Handle the exceptions explicitly ### Deal has no approved bill-to customer Route to finance with the missing legal entity; do not create a customer from an email domain. ### Project changes branch Review the cross-reference and permissions before moving associations; retain the historical source identifiers. ### Invoice is voided or credited Return the corrected finance state with its reference and preserve the original invoice history. ## What to verify before expanding - HubSpot shows the correct Acumatica customer for a multisite account. - Project setup waits for the agreed commercial prerequisites. - Draft invoice data cannot be mistaken for released billing. - A corrected project association removes the stale customer-facing link. ## Connect this process to the rest of your operation [Explore Stacksync two-way sync](https://www.stacksync.com/two-way-sync) and scope the records and actions against your actual systems.

Yes. It can display approved customer and project context while Acumatica owns accounting records. The useful scope is the information needed to answer the customer, not a second editable ERP inside the CRM. Do we need HubSpot custom objects? Not always. Company, deal and contact fields may support a first release. Dedicated site or project objects can improve the model, but their availability and association behavior need validation against your HubSpot plan. Can this automatically release an Acumatica invoice? Invoice release is a separate financial action. Verify the required endpoint, workflow action and authority before automating it; synchronizing a draft or a status field does not authorize release.
