Google Ads budget or agency fee? The cost difference explained

The media budget pays Google for delivering the ads. The management fee pays an external operator for planning, management and oversight of the account; setup, tools, creative work and internal time come on top.

Which costs belong in which category?

Five cost types are regularly mixed into a single figure. They have different payees, supporting documents and approval processes.

The test: who issues the invoice, for what, and on what contractual basis? A reduction in one category is not a reduction in another.

How maitiq charges for management: the offer covers the management fee line only and applies per account. The fee is not tied to the media budget – maitiq does not earn more when your advertising spend rises.

Who owns the account into which the media budget flows?

The media budget is used in the Google Ads account to pay for advertising costs. Ideally your own company remains visible in the account and payment structure. Google sets out clear rules for this: a client account has at most one directly linked manager account designated as owner – it may have none –, keeps its data and can unlink it again. Rights inherited from ancestor manager accounts remain in the manager account structure. When unlinking, ownership must be distinguished from billing and conversion dependencies; the agency handover guide describes the process. Separately, Google assigns the access levels “email only”, “billing”, “read only”, “standard” and “administrator”; only standard and administrator can edit campaigns. These levels answer “who may do what?” in technical terms – they do not govern financial approval.

How does the average daily budget work?

You set the average daily budget per campaign; Google also documents a campaign total budget, which is available only for new campaigns. Google’s help pages name a daily limit of twice the average daily budget – overdelivery – and a monthly limit, in each case “for most campaigns”. The monthly formula assumes an unchanged average daily budget:

Monthly limit = average daily budget × 30.4

30.4 is Google’s calculation value for the average number of days per month. If overdelivery pushes spend past the monthly limit, Google applies an overdelivery credit. By way of illustration: with an average daily budget of CHF 100, the formula gives CHF 3,040 per month, and up to CHF 200 is possible on a single day.

CHF 100 is therefore not a hard daily cap, and the monthly limit is a billing limit set by the provider, not an internal exposure limit. According to the English help pages, both multipliers apply to most campaigns and not to the second budget type. If you need a binding upper limit, define it yourself as an authorisation, monitoring and stop rule. How to manage spending over the period against that limit is covered in the budget pacing guide.

What happens when the budget changes mid-month?

A change does not apply retroactively to the whole month; it recalculates the remaining days:

new monthly limit = amount already spent + (new daily budget × remaining calendar days)

Two rules apply differently here; the remaining calendar days include the day of the change.

• For the daily limit, the highest daily budget set on that day counts. If you raise the budget in the morning and lower it in the afternoon, the higher cap remains in force for that day.
• For the monthly limit, only the most recently valid average daily budget counts.

It follows that the current budget figure does not explain a past month. For reconciliation you need the costs actually incurred and a change log with the date, the old and the new value, and the person who made the change.

Why does the amount charged differ from the campaign costs?

Costs and charges fall at two different points in time. With postpay, advertising costs arise first; the charge follows later – when the payment threshold is reached and on the first day of the month. The threshold can rise automatically, the amount charged can sit slightly above it when costs accumulate quickly, and several charges are possible within one month. If ads are stopped, accrued costs that have not yet been paid remain owed.

An account statement therefore does not answer the question “How much did the campaign cost in August?”. Each of these three figures needs its own source:

1. accrued costs for a period – from the account, in the account time zone and account currency;
2. charged or invoiced amount – from billing, payment record or invoice;
3. approved planned amount – from the internal plan.

All three can differ from one another without any of them being wrong.

Is there a hard spending cap in the account?

Yes – Google documents two, at two different levels. Neither of them is the average daily budget.

The campaign total budget does not depend on the payment setting, but it is limited to new campaigns.

The account budget stops delivery once the amount has been spent or the end date is reached, and it depends on a chain of requirements:

1. Monthly invoicing. Google’s criteria include a company registered for at least one year, an account active in good standing for at least six months, and spend of at least USD 5,000 per month or the local-currency equivalent in at least three of the last twelve months. The criteria may change.
2. Credit line. It must cover the costs not yet invoiced, the costs invoiced but not yet paid, and the costs that continue to accrue while payment is being processed – a payment capacity, not an approved campaign budget and not financial approval.
3. Account budget. Only this step creates the account-wide stop. If it is set to “unlimited”, the amount limit is removed; an end date can still stop delivery.

This chain applies only to the account budget; generalising it wrongly turns it into a requirement for every fixed spending cap. In any case, the internal limit follows from none of these Google settings.

Who controls which figure?

A short responsibility matrix prevents payment access, campaign changes and financial approval from being confused. The roles are placeholders; one person can hold several of them.

An agency can propose and carry out a budget change without holding the financial authorisation. Exactly this separation belongs in the contract and the access levels.

How maitiq charges for management: a budget proposal states the action, the rationale and the data basis with the old and the new value; approval is given manually by your named role or through a bounded Autopilot, and implementation remains its own step, authorised and logged separately.

How is the agency fee calculated?

The fee can be fixed, percentage-based, time-based, project-based or hybrid. Under the percentage model, management fee = chargeable base × rate. What matters is the base defined in the contract: planned budget, accrued costs, charged amount or a narrower selection of accounts and campaigns. A budget increase changes the fee only if the contract links the two. Model logic, minimum fees, tiers and caps are covered in Managed Google Ads in Switzerland.

Illustrative total budget

Freely chosen assumptions with no market reference, purely to demonstrate the categories:

• annual media budget: CHF 500,000;
• management fee: CHF 50,000;
• setup and tools: CHF 14,000.

The planned total spend is CHF 564,000. The management fee is CHF 50,000 – not CHF 550,000 and not CHF 564,000. A reduction in the fee must not count the unchanged media budget as a saving. This is exactly the line maitiq addresses: for a comparable scope of services, maitiq quotes the management fee at half of what a classic Google Ads agency charges, by its own account – the media budget is unaffected and goes to Google unchanged.

Applied to the illustrative fee of CHF 50,000, that gives CHF 25,000; media budget and setup remain unchanged (illustrative example, no client data).

Total budget worksheet

The worksheet is a table to copy and complete; it is not an interactive tool and does not calculate anything automatically. It brings the five cost categories together in detailed rows, which can be broken down further per category. All inputs start empty, with no pre-filled values and no “typical” figure.

Derived values: non-media operating costs = management + setup/extras + internal time and total spend = media + non-media costs + taxes − credits. The formulas apply per column – plan, accrued costs, charged/invoiced – with the same period and scope. Record taxes and credits separately: capture media and the other costs excluding the separately added taxes and the separately deducted credits; if amounts are already net, mark them as such and do not count them twice. The ratio management ÷ media describes the management costs relative to media costs, not as a share of total costs.

Rules:

• An empty field means unknown and blocks the total; it is never summed as zero. A deliberate zero is recorded explicitly and remains distinguishable from unknown.
• When media is zero, the management-to-media ratio is undefined – not 0%.
• Different currencies or periods block the comparison until a documented normalisation with exchange rate and reference date is in place.
• Negative costs are not permitted; credits have their own field and a documented rule.
• Every row carries its source: the plan from the internal decision; accrued media costs from Google Ads; accrued fees, internal time, tools and extras from contracts, service invoices or time records; taxes and credits from the respective document.
• The media line also carries the budget object: average daily budget, campaign total budget or account budget. Without this detail, the planned value is checked against the wrong Google limit.

How maitiq maintains this separation

maitiq takes on the management line of the worksheet as a managed service: an offer per account, with media budget and fee remaining two separate figures. Budget pacing and budget reallocation run daily by default; the configured cadence may differ. Every proposal states the action, the rationale and the data basis with the old and the new value, approval is given manually by your named role or through a bounded Autopilot, and implementation remains its own step, authorised and logged separately. The entry point is the read-only audit, which shows your account’s budget object and delivery and completes the plan comparison with the plan and invoice documents you supply.

How do you reconcile the plan, Google billing and the agency invoice?

1. Fix the period, currency, account time zone and the accounts included.
2. Record the period’s accrued media costs from Google Ads.
3. Place the charged or invoiced amounts alongside them; an exact match is not to be expected, because threshold charges and credits shift the timing.
4. Check the budget object, budget changes and the people who made them in the change log.
5. Apply the contractual fee formula to its defined base.
6. Separate setup, extras and internal time, and explain each difference individually.

An invoice can be correct even though the plan was not fully used, or it can differ because the budget or scope of services was changed. Reconciliation answers the accounting logic first, not the financial impact.
