Before you pay for transport and materials for a client's project, check whether your service fee covers them. Follow any employer requirement for pre-approval. Reimbursable expenses are expenses permitted for a claim under an agreement or policy, subject to its evidence and approval requirements. They are not just any expense you incur while working.
Confirm eligibility before spending
Agree the expense categories, business purpose, budget or amount limit, approver, evidence, submission timing and whether markup is allowed. Document project exceptions. For a purchase outside the standard policy, obtain pre-approval: identify what is being bought, why, the expected amount and who is responsible for reimbursement.
- Agree the eligible category and business purpose.
- Agree the amount limit and whom to obtain approval from.
- Check the receipt or other evidence required.
- Confirm rules on markup and submission.
Capture the original expense
Record the date, supplier, expense, original amount and currency, tax, payment method, business purpose and project. Retain the original invoice or itemized receipt, proof of payment and any required written approval. Connect the claim to the transaction so the same cost is not claimed multiple times through different reports.
Card charges may be split between clients or uses. Don't charge the full amount to each client; retain the original total and a reasonable allocation basis. Separate personal expenses and ineligible costs. A business trip does not make every purchase reimbursable.
Account for refunds, points redeemed and supplier discounts in the actual claim. Don't claim outlays that did not occur.
- Keep full transaction details.
- Retain an itemized source document.
- Identify the project or client.
- Document the basis for a cost split.

Request or invoice the reimbursement
Submit an expense report or separate client-invoice lines for approved expenses, as agreed. Provide a schedule if required. Use descriptions and amounts that match the approved original evidence unless an agreed markup or currency-conversion rule applies. Include the expense period, receipt and approval references, applicable tax treatment and total amount payable. Do not claim the same expense twice.
Don't obscure costs in the service fee when the agreement requires itemization. You may summarize by expense category with an attached breakdown, or show a few costs on separate lines. Confirm any separate-report requirement and tax treatment under the agreement and applicable local rules.
- Use the agreed submission method.
- Include receipt and approval references.
- Explain any agreed conversion or markup.
- Do not claim the same expense twice.
Reconcile repayment to the cost
When repayment arrives, relate it to the original expense, report or invoice line. Record partial payments, rejected amounts and adjustments while retaining the original cost. An expense might be recorded and approved without yet being paid. Record claimed, approved and received amounts separately, then adjust the remaining balance after receiving payment.
- Match repayment to the source expense.
- Record partial or denied amounts.
- Maintain the outstanding balance.
- Keep evidence of the cost and repayment.
Agree what can be claimed before spending
Software subscriptions, computers and office rent are usually considered in service pricing. Transport or materials arranged for a specific client on a pre-agreed basis may be charged back separately. A work-related expense does not mean the client is obliged to pay extra. The same expense may be included in one quotation and charged back separately in another. There is no general list of costs every client must reimburse.
Specify what the service fee covers, what passes through at cost and what follows another charging arrangement. For example, routine remote communication might be included in a fixed fee, while a client-requested out-of-town site visit follows a pre-approved budget.
General travel authorization may not cover premium tickets, extra hotel nights or route changes. Unusual purchases or those involving significant amounts need a specific decision.
In a hypothetical arrangement, the client agrees to reimburse transport against actual evidence up to CNY 300, with prior confirmation before exceeding the limit. Materials follow a pre-approved purchase list, and lodging standards are agreed separately. Explain fees and markup in advance. In an at-cost arrangement, do not hide profit by inflating a receipt amount. A proposed service clause could read:
The service fee does not cover round-trip travel to your site. You reimburse me for transport against actual evidence up to CNY 300. If I expect to exceed the budget, I will explain why and ask for confirmation before making the arrangements.
“Reasonable expenses” may mean different things to you and the client. Specify categories, budget, the threshold for further approval and the approver. Provide options and costs before a change whenever possible. Say your flight budget is CNY 1,200. After the travel dates change, the lowest suitable fare is CNY 1,600. Explain the difference and alternatives to the client, and let them decide whether to change dates or accept the new budget. Agreement is harder after the ticket has been bought.
Keep the cost and the claim connected
Include client-visible information such as the date, supplier, purpose, cost, currency and evidence reference, with approvals when needed. Handle sensitive information appropriately, including only what is needed for the business review. The client should be able to follow the total back to individual costs without asking about each one.
Link this breakdown to the underlying transaction and any reasonable allocation of costs. Include refunds, points used and supplier discounts in the claim. Keep separate records of the expense, submitted claim and payment. Changing one should not erase the others.
Decide how it appears on the client invoice
Some contracts pay back the actual cost. Others may allow a procurement-management or financing fee. Decide the method first and reflect it in the document. For example, do not bill a purchase costing CNY 500 as “reimbursement CNY 650” without revealing the service fee. Explain how any permitted markup or fee is calculated, and confirm the accounting and tax treatment.
Who bears the cost is a matter of contract. How each party accounts for it and whether it is taxable need separate consideration. Treatment of advances, pass-through costs, resale and expense reimbursement may differ depending on the arrangement and jurisdiction. Marking a line “reimbursement” does not make it tax-neutral. Do not simply use your supplier's tax amount.
Keep complete transaction records, contracts and relevant supporting documents. Confirm the treatment for your actual arrangement and jurisdiction. For complex amounts or arrangements, take one or two examples to a qualified bookkeeper or tax adviser for guidance relevant to the transaction.
Account for advances and company-paid purchases
Once a client expense advance has been received, settle it against the costs incurred and money already received, showing the balance owed or refundable. When reconciling eligible personal outlays, deduct the applicable part of an expense advance already received by the claimant. Record company-paid purchases as required, without reimbursing the claimant again for them.
In a different example, all amounts use the same unspecified currency. Eligible personal outlays are 600 and an advance of 200 has already been received, leaving 400 to reimburse, assuming no other adjustments. Keep the expense, advance and eventual repayment records. Reimbursement does not eliminate the original cost.
When a claim is disputed, identify the reason
Is the issue eligibility, approval, evidence, submission timing or amount? Provide the relevant information and record the outcome. A receipt with an unclear purpose may need an explanation. A purchase outside the allowed scope may need a policy decision. Sending the same file again will not help in either case.
Don't change facts to fit a rule. Appropriate exceptions should be recorded by someone with authority through the required process. Explain the difference when only part of a claim is approved. Improve the instructions before the next purchase to address recurring problems.
Track reimbursement as its own status
Review outstanding reimbursements while the transactions are still easy to verify. Address missing evidence, late submissions and client disagreements promptly. Keep the original expense and proof of repayment. Don't let routine expense records hide money that has not been recovered.
Submitted or approved is not the same as paid. Track claimed, approved and received amounts separately, along with the remaining balance. Where a problem recurs, clarify the approval or evidence instructions before the next purchase.
Frequently asked questions
What happens when you have already spent the money without an agreement?
Present the purpose, evidence and communication history, then discuss whether the client will accept it. This does not promise reimbursement, but it is easier to work through than simply increasing the invoice amount.
Is reimbursement always tax-neutral?
Not necessarily. It depends on the arrangement, evidence, jurisdiction and applicable rules. Advances, resale and reimbursement may be treated differently. Ask a qualified professional for advice on the particular transaction.
Can I add markup to a reimbursable cost?
Only if the agreement allows it. Show the calculation and confirm the accounting and tax treatment.
Should reimbursable costs have receipts?
Keep itemized receipts or other required evidence under the policy and applicable rules. Connect approvals and the business purpose to the supporting documents.
