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 Ignacio Malpartida · GTM Engineer Published September 18, 2026 Read time 4 min read APP TIPS ## The operating decision A construction finance Genie needs explicit exception rules for ambiguous job coding, duplicate documents, arithmetic differences and unapproved work. Each exception should identify the affected lines, supporting evidence, decision owner and allowed next step. Keep detection separate from resolution: the agent can identify two similar receipts or a missing approval, but that does not authorize deleting a document, choosing a cost code, or approving additional work. 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: Construction invoice exceptions a Genie should escalate](https://www.stacksync.com/images/blog-highlights/icp-construction-invoice-and-expense-exceptions-missing-cost-codes-duplicate-receipts-and-unapproved-work.webp) ## What this looks like in construction services and installation In an electrical service business, two employees submit photographs of the same store receipt. Another receipt uses a closed project's nickname, and a supplier invoice includes a part installed before the customer approved it. The amounts are small enough to look routine, yet they require different decisions. One needs duplicate review, one needs job identification, and one needs commercial authorization. A useful exception queue tells finance exactly which decision is missing. ## Records, ownership, and update rules | Record | Owner | Operating rule | | --- | --- | --- | | Exception case | Finance operations | Keep a stable case key tied to the source document and affected line. | | Duplicate candidate | Accounts payable | Record both document references and existing payment or posting evidence. | | Missing coding evidence | Job administration | Request a valid job and approved cost code from the responsible owner. | | Approval gap | Project or service manager | Resolve whether the work was authorized before finance treats it as billable or reimbursable. | ![Record ownership diagram: Exception case, Duplicate candidate, Missing coding evidence](https://www.stacksync.com/images/blog-diagrams/icp-construction-invoice-and-expense-exceptions-missing-cost-codes-duplicate-receipts-and-unapproved-work.webp) *Define the record owner and the rule before enabling updates.* ## Work through the process 1. 01 Classify the actual missing decision Use a small set of operational categories: identity, coding, duplicate, amount, approval and access. Record more than a generic low-confidence score. Finance should know whether it needs a clearer receipt, a job owner's decision or a customer approval before opening the document. 2. 02 Compare duplicates with context Check issuer, date, amount, receipt number and line content, then compare against existing entries. A repeated photograph is different from two legitimate purchases for the same amount. Preserve both submissions and ask the reviewer to confirm the duplicate; do not silently delete evidence or mark an employee claim fraudulent. 3. 03 Keep coding proposals constrained When the job or cost code is missing, show the permitted candidates and the evidence that narrows them. A closed job, an inactive code or another branch's project should remain blocked unless the owning team authorizes the correction. The model must not make a new code to complete the form. 4. 04 Route authorization gaps separately Unapproved work is not merely missing data. Send it to the service or project manager with the original scope and the additional line. Finance can record the supplier obligation under its own process while separately deciding whether the cost may be charged to the customer; those are different business questions. 5. 05 Resume from the resolved case Store the review decision, reviewer and corrected values. Recheck the original document and any already-created downstream record before resuming. A retry should continue the same case rather than create another expense. Track repeated exception reasons to identify supplier, field-entry or process changes that would prevent them. ![5-step operating sequence: Construction invoice exceptions a Genie should escalate](https://www.stacksync.com/images/blog-diagrams-mermaid/icp-construction-invoice-and-expense-exceptions-missing-cost-codes-duplicate-receipts-and-unapproved-work.webp) *Follow the operating sequence; unresolved exceptions return to a responsible reviewer.* ## Handle the exceptions explicitly ### Same total appears on two receipts Use document and transaction evidence to distinguish duplicate images from separate purchases. ### Valid cost code belongs to another branch Request the correct authorized mapping instead of borrowing the code to clear the queue. ### Expense is real but customer approval is absent Separate internal expense treatment from the decision to bill the customer. ## What to verify before expanding - Every exception has one named decision owner. - Duplicate review preserves both source references. - A resolved case resumes without creating a second entry. - Approval gaps remain visible even when arithmetic and coding are valid. ## Connect this process to the rest of your operation [Explore Stacksync AI agents (Genies)](https://www.stacksync.com/ai-agents#genies-job-icp-construction) and scope the records and actions against your actual systems.

Block the affected decision at the appropriate level. Some invoices can be reviewed line by line; others require the entire document to remain on hold under finance policy. Can the agent learn from corrected coding? Reviewed decisions can inform future proposals, but they should not replace current permissions or the active cost-code list. A past exception does not authorize the same treatment for every future job. What is the best exception dashboard? Show case age, reason, owner and the work or amount affected. Raw model confidence is less useful than knowing which unresolved decision is delaying finance.
