Contractor expense tracking connects the purchase evidence, funding source, business purpose, project allocation and approval to the final accounting entry. A receipt image and a card transaction may describe the same purchase, but neither by itself establishes the approved job cost.

Preserve the receipt and purchase context

Capture the original receipt with purchaser, date, supplier and business purpose while the details are available. Retain the file after OCR so reviewers can check extracted totals and line items. Mark illegible fields as uncertain. For a store purchase covering two projects, ask for the allocation basis rather than assigning the entire receipt to the worker’s current job. A useful intake process collects enough context to resolve the expense without repeated calls days after the material has been used.

Identify who funded the purchase

Separate company-card transactions, employee-paid expenses, cash advances and supplier invoices. Each follows a different settlement process. Matching a company-card receipt should not create an employee reimbursement. An employee reimbursement request should identify any advance or partial repayment already received. Use transaction identifiers and dates to detect possible duplicates without assuming similar amounts are identical purchases. AI can suggest matches, but uncertain cases should remain in review so automation does not turn a duplicate document into a second payment obligation.

Allocate costs with an explainable basis

Link the approved expense to the correct project, cost code and any relevant change work. Split allocations should add up to the supported amount and preserve the reason for the split. If materials serve multiple jobs, use the company’s approved method and retain supporting notes. Tax treatment and capitalization questions belong with the accounting reviewer. A category suggested by OCR or AI is only a proposal; it cannot determine the business’s accounting policy or resolve missing purchase context.

Separate policy review from money authority

Check required documentation, permitted purchase types and approval thresholds using the applicable policy. Identify the approver and any exception decision. A complete receipt does not automatically authorize reimbursement, and a policy exception should not disappear after a manager adds a comment. Preserve the approved values before exporting them. Restrict sensitive payment information and give reviewers the evidence relevant to their role. Where the business requires more than one approval, the workflow should show which decision remains outstanding.

Verify the destination and handle corrections

After posting, retrieve the accounting entry or other reliable confirmation and compare amount, project, account and external reference. A successful integration response is not enough if the cost landed on the wrong job. Make retries duplicate-safe and give failed records a visible owner. Record later credits and corrections with links to the original expense. Measure missing receipts, allocation changes after posting and duplicate-payment exceptions. Pilot with a split purchase and a returned item before expanding automated posting across all field expenses.
