An agency can sell two activities for the same client total and earn very different amounts. One product may pay commission on an eligible base; another may allow an approved markup above a net amount. Neither number is automatically the agency's profit, and neither should be confused with the cash arriving in a bank account.
The examples below are hypothetical operating illustrations in a single currency. They exclude taxes and accounting treatment, which depend on the transaction and business. Their purpose is to improve quoting decisions, not prescribe a commission rate, selling price or legal structure.
Name the model before calculating the earnings
In a commission arrangement, the agency's remuneration is calculated under the supplier or platform agreement. The agreement might define a percentage, a fixed amount, an eligible base and conditions that must be met before earnings are payable. Read those details rather than treating the headline rate as a complete calculation.
In a markup arrangement, an eligible net amount is increased to produce the client's selling price, within whatever restrictions apply. Permission may depend on the product, account, channel or guardrails. A product showing a net amount is not by itself an invitation to charge any price you choose. An agency service fee is another distinct component and should be handled according to the agency's terms and applicable requirements.
Record a model field for each quote line: commission, eligible markup, fixed remuneration or another expressly agreed arrangement. Add the source and date checked. This prevents a colleague from copying last month's percentage into a different product. If the commercial basis is unclear, stop the calculation and obtain clarification. A precise spreadsheet based on the wrong model produces a confident error, and that error can survive all the way to the monthly earnings review.
Distinguish markup from margin
Markup and margin use different denominators. Markup compares the amount added with the underlying cost. Margin compares the amount retained before the relevant costs with the selling price. Xero's explanation of markup and margin confirms this distinction, which is useful even when your agency uses another accounting system.
Suppose, hypothetically, an eligible activity has a net amount of 200 units and your agreement permits the chosen markup. Adding 20 percent of 200 creates a 40-unit uplift and a selling price of 240. The uplift is 20 percent of the net amount, but 40 divided by 240 is approximately 16.67 percent of the selling price. A 20 percent markup is therefore not a 20 percent margin.
If your goal were a 20 percent margin before other costs, the hypothetical selling price would be 200 divided by 0.80, or 250. That is a calculation, not permission to charge 250. Commercial limits and client value still control the decision. Give the tracker unambiguous column labels such as markup percentage on net and uplift as percentage of selling price. A single column called percentage invites staff to compare numbers that describe different things.
Check the base and the conditions for commission
A hypothetical 10 percent commission on a 300-unit eligible base produces 30 units of expected commission. If the client total includes a separate 50-unit component that is not eligible, the total collected could be 350 while the expected commission remains 30. Applying 10 percent to 350 would overstate earnings by five units.
The actual agreement determines whether taxes, fees, add-ons, discounts or other components are included. Do not infer that from the way a client-facing total is displayed. Keep the eligible base and expected earnings together in the internal record, with a reference to the current commercial terms. Ask how cancellations, partial refunds, changes and no-shows affect the calculation.
Use a short verification checklist before issuing the quote:
- What model applies to this product and account?
- Which amount is the eligible base?
- What rate or fixed amount applies now?
- What restrictions affect the selling price?
- What events can change or reverse the expected earnings?
This is especially useful when one quote combines several suppliers. A group total can be commercially clear for the client while containing different internal earnings models. Calculate each line on its own basis before combining the result. Averaging headline rates first can conceal the effect of a low-earning or non-eligible component.
Calculate contribution after the agency's own costs
Expected gross earnings are only the beginning of an operating decision. Identify the costs your agency bears on that booking: payment costs if applicable, currency conversion, a subcontracted service, a specifically allocated delivery cost or other transaction-linked expense. Distinguish these from general overheads so you understand what the calculation answers.
For a hypothetical commission of 30 units, assume the agency bears five units of transaction costs and estimates fifteen units of staff time directly required for the case. The remaining contribution under those stated assumptions is ten units. If the staff time was already included elsewhere in your model, subtracting it again would double-count the cost. Write the assumptions beside the result.
Compare a more complex booking with a simpler one through the same method. A higher commission can be less attractive if the agency must spend many more hours coordinating exceptions. This does not mean rejecting clients with complex needs. It means pricing and resourcing the service honestly, choosing suitable products and understanding where the work sits. Review the assumptions against actual experience. A staff-time estimate that never changes after difficult cases is a decorative number, not a useful management input.
Keep currency and rounding visible
Separate the currency shown to the client, the currency used for supplier obligations and the currency in which the agency receives settlement. They may match, but do not assume they do. Record the conversion basis, its check time and who bears any change between quoting and payment.
Stripe's currency documentation illustrates the distinction between charging and settlement currencies within its own payment service. It does not establish how Tripnatic or a particular supplier handles your booking. Use the distinction as a question to verify with the service you actually use. Avoid treating a public exchange-rate search as the exact amount that will reach your account after fees and conversion.
Set a written rounding rule for your internal calculator and client totals. Google Sheets documents the ROUND function, which can help implement a chosen rule, but the rule itself should match your commercial requirements and currency handling. Decide whether you round individual lines or only the final result, then reconcile the difference. For a group with many small items, inconsistent rounding can create an unexplained gap between the proposal, supplier bill and payment request. Keep the original calculation available for review.
Present a clear client price without exposing irrelevant workings
The client needs to understand what they will pay, in which currency, for which services and under which conditions. They do not need your entire internal profitability model. Separate the client-facing proposal from cost and remuneration notes, while making the client total and required fees clear.
The Australian Competition and Consumer Commission's price-display guidance addresses clear pricing and the problem of progressively adding charges within Australian consumer-law scope. Agencies operating elsewhere should check the rules relevant to their market and selling model. Do not assume a B2B supplier quote and a consumer-facing offer have identical presentation requirements.
Operationally, show the full known client cost for the agreed scope, identify optional components and avoid a low headline price that depends on unavoidable additions later. If the amount cannot yet be finalised, state the reason and what must happen before confirmation. A service fee should not appear unexpectedly after the client has chosen the product. When comparing alternatives, use like-for-like totals. A cheaper activity without the required transfer is not a cheaper complete solution until the transfer cost and practical implications have been considered.
Treat discounts as a fresh calculation
A discount changes the economics even when it looks small to the client. Do not subtract a percentage from the selling price and assume the same agency earnings remain. Check which party funds the reduction, whether the eligible commission base changes and whether a minimum or maximum selling constraint applies.
Suppose, hypothetically, the permitted markup example has a 200-unit net amount and a 240-unit selling price. Reducing the selling price by twenty units leaves a twenty-unit uplift rather than forty, before other agency costs. The client receives a reduction of about 8.33 percent, while the agency's uplift is halved. That difference is why discounts need an approval rule based on retained contribution, not just a percentage of the client total.
Create a simple exception note: original total, proposed reduction, who funds it, revised expected earnings, relevant costs, reason and approver. Do the same for a complimentary add-on that costs the agency money or staff time. It may be a sensible service decision, but it still has a cost. Avoid promising a future commission-funded discount before the current commercial terms and eligibility have been verified. Expected earnings can change, and a goodwill promise may outlast the income intended to fund it.
Separate expected, approved and paid amounts
A booking can be confirmed while earnings remain expected. A completed service can still be subject to eligibility checks, adjustments or a payment schedule. Treat the stages separately so the agency does not spend money it has only forecast.
Use fields for expected amount, latest adjustment, approved amount, payment status and reconciliation reference. The exact labels should match the platform or supplier's current terminology. Keep the history of changes rather than replacing the original expectation with a final number that obscures why the difference occurred. Review outstanding items by age and reason: awaiting completion, pending review, queried, reversed or due for payment.
Tripnatic agents can see expected earnings before confirmation and use commission or eligible markup subject to product and guardrail limits. That does not establish a universal rate, an unrestricted markup right or an instant payout. Check the current account information and terms for the actual booking. When a client change affects the booking, review the earnings too. A partial cancellation can leave the remaining service valid while changing the remuneration. The agency's client-service record and internal commercial record should reflect the same revised scope.
Use a small control sheet and review real exceptions
A practical internal line record contains the quote reference, product, travel date, currency, client total, commercial model, eligible base, expected earnings, agency-borne costs and approval status. Add the source of the current terms and the person who checked them. Keep access limited to staff who need commercial information.
Review a few completed bookings each month. Compare expected earnings with the final approved amount and the cash received, then investigate the largest differences. The purpose is not to punish every estimate that changed. It is to identify recurring causes: the wrong commission base, unrecorded discounts, forgotten transfer costs, currency differences or excessive manual rework.
If you are considering a dedicated agency workspace, the Tripnatic agent page explains the role and the registration route begins the account process, with applicable verification and approval before activation. Pair the commercial calculation with a clear quote workflow so the client approves the right version before booking. A useful pricing system makes the model, assumptions and status visible. That is more valuable than chasing the largest headline percentage without understanding what the agency will actually retain.
