Multi-Location Interior Contractors: Align Salesforce Project Sites With Acumatica Billing Contacts

What this looks like in commercial flooring and interior installation

A flooring and interiors contractor works on several retail locations for one general contractor. Each location has a different superintendent, while invoices go to a central project-accounting team with location-specific references. Salesforce groups the relationship under the contractor account; Acumatica holds the approved projects and billing details. The integration must connect the right contacts to each job so a superintendent's phone update does not overwrite the accounts-payable recipient.

Records, ownership, and update rules

Work through the process

1. 01
   List parties by function

   For a representative project, identify purchaser, payer, site contact and acceptance authority. These roles can belong to different organizations. Map the role explicitly so the integration does not choose an invoice recipient from whichever contact was most recently edited in the CRM.
2. 02
   Keep project references stable

   Join Salesforce project context to the approved Acumatica project using an external cross-reference. Include branch or company context where identifiers might repeat. Preserve the customer's project number separately from your internal job number so customer-facing documents can use the required reference without changing internal identity.
3. 03
   Separate contact attributes from authority

   Phone and email updates can be useful routine changes, but permission to approve work or receive invoices is a role assignment. Treat a change in authority as a reviewed relationship update. Do not infer it from a contact title or the fact that a person appears on recent correspondence.
4. 04
   Validate the accessible entities

   Confirm the Salesforce representation for project sites and contact roles, including any custom objects. Inspect the Acumatica endpoint and permissions for the intended project and contact fields. Use a limited pilot to verify updates and associations, not only record availability in the connection screen.
5. 05
   Test changes during live work

   Simulate a new superintendent, a changed billing recipient and a site moving to another project manager. Check which current records should update and which historical documents must preserve the original recipient. Ask field coordination and accounts receivable to review the results separately.
6. 06
   Preserve the customer's document-routing rules

   Some customers require invoices or supporting evidence to reference a particular location, contract or project code. Store that requirement at the level where it applies and have finance verify it. A central billing email is not enough when each project uses a different reference. The synchronized summary should help the account team answer routing questions while the original approved instructions remain available to the people preparing the financial documents.

Handle the exceptions explicitly

One contact serves several locations

Keep separate role associations so a change at one site does not remove the others.

Customer requires different PO references by site

Retain the reference at project or billing scope rather than one account-wide field.

Billing email changes after an invoice is issued

Update future delivery instructions while finance controls any resend or document correction.

What to verify before expanding

• Site-contact changes do not redirect financial documents.
• Every location resolves to the correct internal and customer project references.
• A contact can hold different roles on different jobs.
• Historical invoice recipients remain traceable after a contact update.
