THE USEFUL ANSWER
Compare Substy plans on the same eligible-sales base, then check the features you actually need. A lower percentage can carry a larger fixed fee; a cost crossover alone does not establish which plan fits.
- Compare the fixed fee and the eligible-sales percentage together.
- Check the supported workflow before choosing the lowest modelled cost.
- The examples explain arithmetic; no hands-on performance winner is claimed.
- Fee base
Which transactions attract the charge?
- Workflow
Which required jobs and controls are included?
- Evidence
What did your own bounded trial establish?
Start with the job the plan must cover
A plan can look cheaper and still leave the required workflow unsupported. Write down whether you need generated drafts, reviewed sending, automatic replies or team coordination before comparing a percentage. Use the comparison memo to record the same questions for every candidate.
This is a sourced discussion of fee structures and a proposed evaluation method. It is not a head-to-head product test, and no plan is assigned a measured quality score.
Read the fixed and variable parts together
The Substy pricing page is the source for the dated plan snapshot. The monthly OnlyFans offers checked on 10 September 2026 listed Starter at $0 plus 15%, Pro at $69 plus 10%, and Elite at $99 plus 8.5% per creator. The stated percentages use net AI sales. Confirm the current offer, applicable platform and fee definition before purchasing.
| Question | Why it matters |
|---|---|
| Which transactions count as net AI sales? | A percentage needs a defined denominator |
| Which actions are included in each tier? | Lower cost does not imply the required workflow is covered |
| Is the fixed fee per creator? | Several accounts change the total commitment |
| How are refunds and attribution adjustments handled? | The later invoice can differ from a dashboard snapshot |
| What review work remains? | Operator time is a separate cost |
Keep the quote and its date with the worksheet. A screenshot of a starting price without the selected platform, billing period or feature scope is incomplete evidence.
Calculate the fee crossover conditionally
Assume two offers use exactly the same eligible monthly sales base R. A 15% offer and a $69 plus 10% offer are equal when 0.15R = 69 + 0.10R. Therefore R = $1,380.
At a $2,000 base, the first model costs $300 and the second costs $269. The arithmetic says nothing about whether both plans include your required controls. It also does not predict whether a different plan will change sales.
Likewise, $69 plus 10% and $99 plus 8.5% are equal at a $2,000 base: (99 - 69) / (0.10 - 0.085). At that point each model costs $269. This is a simplified unchanged-input calculation, with taxes, review time and other charges excluded.
| Hypothetical equal sales base | $0 + 15% | $69 + 10% | $99 + 8.5% |
|---|---|---|---|
| $1,000 | $150 | $169 | $184 |
| $2,000 | $300 | $269 | $269 |
| $5,000 | $750 | $569 | $524 |
These are calculations using the displayed fee structures, not quotes or statements of equivalent service. If the eligible base differs, stop comparing these totals until the definitions match.
Ask for a demonstration tied to your account
Use the same approved account facts and synthetic conversation cases. Include a corrected fact, missing information, a human handover and a stop action. Record the plan, settings and configuration used for the demonstration.
A successful draft-assistance exercise does not establish that automatic sending has the same behaviour. If the feature cannot be demonstrated, mark it untested. Ask whether the trial has the same feature scope and limits as the intended paid plan.
Do not fill a gap in the evidence with an assumption about the product. Record what the vendor says, what was observed and what remains unknown in separate fields.
Make the decision reviewable
Finish with the required workflow, quoted monthly fee model, expected operating workload and unresolved questions. Keep a dated copy of the agreement and schedule a review of the first invoice against the agreed fee base.
Use the revenue-claim guide before adding a marketing uplift to the model. If you are also evaluating a broader shared inbox, the Infloww and Supercreator comparison explains why account fees and AI scope need separate consideration.
The comparison worksheet keeps the decision, evidence and next test in one place. A justified choice is conditional on the work you need done; the cheapest cell in a table is only one input.
