Compare the total cost of the outcome, not the invoice. A software stack is the cheapest line item and the most expensive in hours. Freelancers cost per task plus your coordination time. An agency costs a fixed fee and buys back your calendar. Price all three the same way.
The short version
- Price your own hour first. Every comparison that skips this step reaches the wrong answer.
- Coordination is a cost, not a rounding error. Managing three specialists is a real part of your week.
- The gap costs more than the invoice. Whatever nobody covers is where the money actually goes.
- The management fee is rarely the biggest number. Inventory and advertising usually dwarf it.
- Re-run this every year. The cheapest option at one product is rarely the cheapest at five.
Cost the three options in six steps
Do this on paper before you take a single call. Each step has a gate, and if you cannot clear it, the number you produce is decoration.
- Put a price on your hour. Use what an hour of your attention earns elsewhere in the business, not minimum wage and not your fantasy rate. Gate: one figure, written down, that you would defend out loud.
- Count the hours each option leaves with you. Software leaves nearly all of the work. Freelancers leave the briefing, reviewing, and chasing. A managed service leaves approvals and supply decisions, which for our clients runs around two hours a month in steady state and four to six hours a week during a launch. Gate: an hours figure per option, per month.
- Add the invoice. Subscriptions for the software column. Rates times expected tasks for the freelancer column. The fee for the managed column, which for us runs $800 a month for one product up to $2,400 for five, with the first invoice covering the first and last month and no onboarding fee. Gate: all three columns quoted for the same scope of work.
- Add coordination. About an hour per specialist per week, more if they work across time zones. Nobody puts this in the spreadsheet and it is often the difference between the columns. Gate: you have added it even though you do not want to.
- Price the gap. List the jobs no column covers, then decide whether they matter. Sourcing and quality control is the classic uncovered gap: no software has an opinion on a supplier, and a copywriter cannot inspect a factory. Gate: every uncovered job either has a plan or an accepted consequence.
- Add switching cost and set a review date. Two to three months of ramp if you change later, and a diary note twelve months out. Gate: the review is actually in the calendar.
The three columns side by side
| Cost element | Software stack | Freelancers | Managed service |
|---|---|---|---|
| Monthly invoice | Lowest | Variable and lumpy | Fixed and predictable |
| Your hours | Highest | Moderate to high | Lowest |
| Coordination load | Yours entirely | Yours, and it grows per specialist | Theirs |
| Coverage of the gaps | None | Only what you bought | Should be everything, so ask |
| Cost of a bad month | You absorb it | You pay per task regardless | Fixed, and you can leave on notice |
| Exit cost | Cancel the subscription | End the engagement | Notice period, then a handover |
Predictability is worth something, and it does not show up in a price comparison. A fixed fee means a bad month costs the same as a good one, which is exactly when a per-task arrangement becomes expensive, because a bad month generates more tasks.
The gap most comparisons never price
Sourcing is where I see the largest unpriced risk. A supplier who ships inconsistent units produces a rating problem, and a rating problem is the most expensive thing to repair on Amazon because it accumulates in public and cannot be advertised away.
None of the cheap columns cover this. A subscription cannot audit a factory. A freelance copywriter cannot read a quality report. If your product comes from Asia and nobody on your side inspects it, that is an open cost sitting in the spreadsheet with no line item. We run an in-house sourcing studio in Guangzhou and work from frameworks built across more than 500 brands, and I mention it here specifically because it is the column that never appears in a price comparison and frequently decides the outcome.
Whatever you buy, ask who checks the goods before they enter a warehouse, and write the answer down.
What most agencies will not tell you
For most brands the management fee is not the expensive number. Inventory and advertising are. Launch capital typically runs $8,000 to $15,000 for a single product and $25,000 to $50,000 for a five-product brand, and we suggest around $1,000 a month of ad spend for optimization to mean anything, though there is no hard minimum. Set against those figures, the difference between a subscription and a retainer is often the smallest decision in the plan.
The second thing: below a certain revenue, the same money does more as inventory than as a fee. A retainer that eats the margin on one product is a bad trade, and we say so in free audits and lose those deals. That is not humility, it is the arithmetic.
