Sell Paid GM Advice & Worldbuilding Help

Experienced Dungeon Masters can sell paid GM advice and worldbuilding help by listing it as a priced Creator Service: the fan describes their setting or campaign problem, pays upfront, and receives written or recorded consulting feedback with a set turnaround — no booking calendar and no marketplace listing required.

FanBell’s pricing page states "12% platform fee per paid transaction · $0/month" and that "the fan pays only the displayed price" (FanBell pricing).

A familiar DM reads: "How do you keep track of your factions?" or "My homebrew pantheon feels flat, can you look at it?" Experienced GMs answer versions of this constantly, usually for free, in server threads or DMs. Turning it into a paid offer doesn't require running a table for the person — it means selling your judgment about a setting someone else is already building. The audience for that judgment is not small: Wizards of the Coast's press release of September 25, 2024 states that Dungeons & Dragons has "more than 85 million D&D fans worldwide and more than 18 million registered D&D Beyond users" (Wizards of the Coast press release, September 25, 2024).

What counts as paid GM advice versus writing a module for hire?

Paid GM advice is feedback and judgment on a world, campaign, or session that someone else is already building. A custom module is a finished document you write for them from scratch. Both involve factions, maps, and NPCs, but the deliverable and the authorship differ: in advice work the fan keeps authorship and you react to their material.

Advice work looks like reviewing a fan's faction write-up and flagging plot holes, suggesting how to pace a political arc, or explaining how you structure a pantheon so gods don't feel interchangeable. If a request turns into "write me a one-shot" instead of "look at what I've built," that's a different offer worth listing separately. FanBell’s how-it-works page answers the question "What if I get a request I don’t want to fulfill?" with "You can decline and refund it. You’re always in control of what you take on." (FanBell, how it works).

Should GM advice be sold as a Paid Private Question or a Creator Service?

Sell GM advice as a Paid Private Question when one narrow question can be answered from text alone, and as a Creator Service when the fan must send a document and receive files back. The dividing line is attachments: only a Creator Service moves files in both directions. Format choice, not price, is the first decision.

FanBell's Paid Private Questions take text only from the fan and are answered by text or voice, with no file upload in either direction.

FanBell's Creator Services page states that a fan ordering a service "can also attach their own files when they order" and that the creator delivers "a written note plus up to 5 files (video, audio, images, PDF, Word, Excel, or PowerPoint)" plus an optional private link for anything larger. FanBell's Creator Services page also caps video and audio deliverables at 20 minutes each. A Creator Service delivery promise in FanBell maxes out at 120 hours — five days — which is the longest turnaround the product will let a creator select.

What can you actually charge for as a worldbuilding consultant?

Worldbuilding advice breaks into a handful of recurring, bounded requests: pantheon and faction consistency, campaign-arc pacing, and "sanity check my homebrew before session one." Scoping each request type as its own tier, with a fixed price and a fixed turnaround, keeps the offer predictable and stops one order from turning into an open-ended editing relationship.

Treat the four turnarounds in the offer-tier table on this page — 24-48 hours, 48-72 hours, 24-48 hours, and 48 hours — as illustrative rather than guaranteed, because actual pricing and delivery windows depend on your audience, your positioning, and how much depth a given request needs. All four of those turnarounds, spanning 24 to 72 hours, sit inside FanBell's 120-hour maximum delivery window.

Can you sell advice about published settings like Forgotten Realms?

You can generally sell your own craft advice about a published setting, and you can sell work built on the D&D System Reference Document, which Wizards of the Coast released under a Creative Commons license. You cannot charge for Fan Content that incorporates Wizards' IP outside such a license. Nothing on this page is legal advice.

Wizards of the Coast's Fan Content Policy, last updated November 15, 2017, requires that fan-made works using its IP stay free:

"Free means FREE: You can't require payments, surveys, downloads, subscriptions, or email registration to access your Fan Content …" — Wizards of the Coast, Fan Content Policy (last updated November 15, 2017)

Three categories sit outside the Fan Content Policy's free-only restriction, and each rests on a different basis:

• Licensed SRD material. D&D Beyond's official SRD page states that SRD 5.1 and SRD 5.2 are both available under the Creative Commons CC-BY-4.0 license, that "the only requirement is that the user must provide attribution," and that users "can use the content commercially and they can make new works based on the content" (D&D Beyond, SRD). D&D Beyond's SRD page, last updated March 2, 2026, lists SRD v5.2.0 as published April 22, 2025 and the current SRD v5.2.1 as published May 1, 2025.
• Your own commentary and craft advice. Wizards' Fan Content Policy defines Fan Content as work "based on or incorporating our IP", and the U.S. Copyright Office states that Section 107 of the U.S. Copyright Act "identifies certain types of uses—such as criticism, comment, news reporting, teaching, scholarship, and research—as examples of activities that may qualify as fair use" (U.S. Copyright Office, Fair Use Index). Paid analysis or teaching that names a published setting without reproducing its text is closer to commentary than to redistribution — but that is a general observation about the statute, not a legal opinion about your specific offer, and the same Copyright Office page lists four factors that a court weighs case by case, including whether the use "is of a commercial nature" (U.S. Copyright Office).
• The fan's own original world. Feedback on a homebrew setting the fan wrote is not Fan Content built on anyone's IP at all.

Published setting names sit on the sharp edge of the Fan Content Policy's free-only restriction. D&D Beyond's SRD comparison table marks "I want to publish content using the Forgotten Realms" as available only through DMsGuild, and not under either SRD 5.1 or SRD 5.2 Creative Commons. D&D Beyond's SRD page also states that the SRD and Creative Commons "do not apply to the use of D&D content in streaming, fan art, cosplay, and other fan content".

Where a request sits close to the line — for example, packaging official lore, stat blocks, or maps into a deliverable you charge for — the Fan Content Policy is explicit that it does not cover "the verbatim copying and reposting of Wizards' IP". Redirect that kind of request toward general design principles, or ask a lawyer in your jurisdiction. The U.S. Copyright Office gives the same instruction on its own Fair Use Index:

"If you are concerned as to whether a particular use is fair, however, or believe that someone has made an unauthorized use of a copyrighted work in a manner that is not fair, it is best to consult an attorney." — U.S. Copyright Office, Fair Use Index

Fair-use analysis is fact-specific and is a doctrine of United States law, so creators outside the US should check the equivalent exception in their own country. The U.S. Copyright Office states plainly that it "is unable to provide specific legal advice to individual members of the public about questions of fair use," and nothing on this page is a substitute for an attorney's advice (U.S. Copyright Office).

How much should you charge for paid GM advice?

Price a worldbuilding review off the word count the fan sends, using professional developmental-editing rates as the floor: roughly $50 for a 1,500-word sanity check, $85 for a 2,500-word consistency pass, and $200 for a 5,000-word setting bible plus a recorded walkthrough. Two published editorial rate references put that kind of feedback at $45 to $70 per hour.

Developmental editing — paid written feedback on someone else's creative document — is the closest priced comparison to paid GM advice, because both sell judgment on a document the buyer wrote.

I could not find a published rate survey that breaks out paid GM advice or worldbuilding consulting as its own line item. The search basis was narrow and checkable: no tabletop, roleplaying-game, or game-mastering category appears anywhere in the Editorial Freelancers Association's 2026 Rate Chart, whose categories run from beta reading to ghostwriting, and Reedsy's freelance editing rate guide likewise breaks out only publishing-editorial services. The Reedsy and Editorial Freelancers Association figures used on this page are therefore proxies for GM advice, not measured GM rates.

Reedsy's rate guide, last updated February 13, 2025, reports that content/developmental editing averages $0.036 per word and $45–$66 per hour, figures the page attributes to "2025 data from Reedsy's marketplace" rather than to an industry-wide survey. The Editorial Freelancers Association's 2026 Rate Chart lists fiction developmental editing at 3.0–3.5 cents per word and $52.50–$70.00 per hour, based on more than 1,100 member responses collected between November 2025 and mid-January 2026 (EFA Editorial Rates).

Three scoped packages, priced directly off the EFA's published per-word rates, make the math checkable for a buyer:

A time-based cross-check lands in the same place. The EFA's 2026 Rate Chart puts fiction developmental editing at 5.5 to 10.0 manuscript pages per hour and defines a page as 250 words, so a 2,500-word faction document is ten pages, or 1.0 to 1.8 hours of work (EFA Editorial Rates). At the EFA's $52.50–$70.00 hourly band, those 1.0 to 1.8 hours price at $52.50–$126.00, and the $85 Setting Consistency Pass sits inside that range.

Take-home on an $85 order is arithmetic you can show a fan. FanBell's 12% platform fee on $85 is $10.20, Stripe's published US domestic card rate of "2.9% + $0.30 per successful transaction" comes to $2.77 (Stripe pricing), and $85.00 − $10.20 − $2.77 leaves about $72.03 before tax. FanBell's pricing page states the same formula as "Creator earnings = fan payment − platform fee − processing fee".

The Reedsy and EFA figures both describe scoped, document-based feedback in publishing, not tabletop consulting, and neither is a FanBell outcome or a prediction of what you will earn. The $50, $85, and $200 package prices on this page are illustrative examples derived from published editorial rates, not benchmarks for what paid GM advice actually sells for.

Is FanBell cheaper than routing GM work through a booking marketplace?

FanBell's 12% platform fee and StartPlaying's 15% booking fee are not directly comparable, because the two cuts cover different things. StartPlaying's 15% is deducted from a scheduled table booking and absorbs its own card-processing costs. FanBell's 12% applies to a written advisory offer sold from your own bio link, with Stripe card processing billed separately on top.

StartPlaying's help center states that its 15% covers "StartPlaying's credit card processing costs and fees to our payment processor, Stripe". The StartPlaying Help Center article "What Does the 15% Fee Cover?", dated April 22, 2026, states that "when a player books and pays, StartPlaying automatically deducts 15% before the remainder is paid out to you," and lists payment processing among the things that 15% covers (StartPlaying Help Center):

"All payments are processed securely through Stripe." — StartPlaying Help Center, "What Does the 15% Fee Cover?"

FanBell's pricing page states "12% platform fee per paid transaction · $0/month" and that "payment-processing fees are deducted separately from creator earnings". Stripe's published US pricing is "2.9% + $0.30 per successful transaction" for domestic cards, plus an additional 1.5% for international cards. What StartPlaying's larger cut also buys is reach: StartPlaying's "Hire a Dungeon Master" page states that the platform has "helped over 80,000 players find their game, group, and Games Master" and lists "5,000+ Game Masters" (StartPlaying, Hire a Dungeon Master). Because StartPlaying's own documentation puts payment processing inside its 15%, do not assume card processing stacks the same way on both platforms — check each platform's current payout breakdown before comparing take-home figures.

When is FanBell the wrong way to sell GM advice?

FanBell fits asynchronous, scoped, single-pass advice. FanBell is the wrong tool when the value of the work is the live conversation, when the relationship is ongoing, or when you cannot connect a payout account. In those cases a booking marketplace, a scheduling tool, or a retainer invoice will serve you better than a link in your bio.

Three concrete cases where a different tool wins:

• You need a scheduled call. FanBell's own documentation states plainly that "FanBell is asynchronous" and that "there are no live video calls or appointments to schedule". Session-zero coaching that only works as a two-hour conversation belongs on a booking platform — the same live-call logic that applies to selling one-on-one gaming sessions with fans.
• You want a recurring coaching relationship. A Creator Service is one defined delivery with one turnaround, and FanBell's Creator Services page frames scope as what "keeps small services from turning into unpaid work". A monthly retainer is a different product.
• You can't connect Stripe. FanBell's pricing page states that "a connected Stripe account is required for paid widgets" and that "to receive money, creators connect a Stripe Express account". Stripe Express availability varies by country, so check that your country is supported before building an offer around it.

If you already run paid tables and your audience arrives through a marketplace's search rather than your own bio, the marketplace's higher cut may still be the better deal, because that cut is buying discovery a bio link does not. StartPlaying's blog reported that, as of December 2023, Game Masters on the platform had earned more than $17 million running tabletop RPGs (StartPlaying blog, March 4, 2024); that total is platform-wide across several years and is not a per-GM figure or a prediction of your own earnings.

What should a worldbuilding-advice listing include?

A clear listing tells the fan what to send, what they will get back, and what is out of scope. Define five things before publishing: the input the fan submits, the scope of the pass, the deliverable format, the turnaround window, and the exclusions. Ambiguity in any one of them is where a scoped review turns into unpaid ongoing work.

• Input: What the fan should submit — a faction doc, a setting summary, or a specific design question.
• Scope: One review pass, not an open-ended editing relationship.
• Deliverable format: Written notes, a marked-up document, a voice walkthrough, or a mix — FanBell allows a written note plus up to 5 attached files per delivery.
• Turnaround: A window you can reliably hit within FanBell's 120-hour maximum.
• Exclusions: State clearly that the offer is not a commissioned module and not ongoing GM-ing for their table.

Here is a finished listing you can copy, change the numbers in, and publish:

Setting Consistency Pass — $85 · 48-hour turnaround

Send me up to 2,500 words of your world: factions, pantheon, timeline, or a setting primer. Paste it in the order notes or attach it as a PDF, Word, or Google Doc export.

You get back a written note — usually 800 to 1,200 words — covering: contradictions between factions or timeline events, motivations that do not survive contact with players, places the lore is thin where a table will push on it, and three concrete fixes ranked by how much table time they buy you.

Included: one review pass, delivered within 48 hours, plus one round of follow-up questions by reply.

Not included: writing new lore for you, statting NPCs or monsters, building encounters, running your table, or ongoing edits after the pass. If you want any of that, order the Commissioned Writing listing instead.

Please note: I give craft feedback on your own world. I do not reproduce published lore, stat blocks, or maps in the deliverable.

Every line of that sample listing maps to one of the five elements: input, scope, deliverable format, turnaround, and exclusions. Copy it into a FanBell Creator Service, and the 48-hour turnaround stays well inside FanBell's 120-hour maximum delivery promise.

What else can a GM sell alongside advice sessions?

Worldbuilding advice does not have to be the only paid option on a GM's page. Shoutouts, tips, project support, and a brand-collaboration intake each capture a different intent, and none of them require the fan to buy a written consult. Keeping the advice listing narrow is what stops a page from becoming hard to read.

• Personalized Shoutout: A quick in-character message or a congrats clip for a fan's own campaign milestone.
• Tips: A way for someone who used your free worldbuilding content to support you without buying a deliverable.
• Wishlist / Project Support: Funding toward a defined project, such as a homebrew sourcebook, tracked with a progress bar.
• Brand Collaboration Inquiries: A separate intake for TTRPG publishers who want to discuss a paid partnership; it organizes leads but does not guarantee a deal.

Keep the advice offer itself narrow — mixing it with unrelated products makes it harder for a fan to know what they are paying for.

How do you get a GM-advice offer live?

Decide whether most incoming requests will be short text questions or document-based reviews, then write one listing around that format. A narrow Creator Service converts better than an open-ended "ask me anything about worldbuilding," because the fan can tell before paying whether their specific problem is the one you have agreed to solve.

FanBell's setup does not require a marketplace application, a GM rating history, or a follower minimum to publish a Paid Private Question or a Creator Service. Receiving money does require a connected Stripe Express account. Set a price and a turnaround you can hit consistently, then share the link wherever you currently answer worldbuilding questions for free — a Discord server, a stream chat, or a table-finding community. Discord's own business blog, published May 14, 2025, states that the platform has "200+ million monthly active users spending 1.5+ billion hours playing games monthly" — a scale that explains why the server where a GM already answers worldbuilding questions is the most natural place to put a paid link.

Frequently asked questions

Five questions come up most often about selling GM advice through FanBell: whether a booking history is required, how published-setting IP is handled, which offer format fits a given request, what to do when a request exceeds the listed scope, and what the whole thing costs. Short answers with sources follow.

Do I need to already run paid games to sell worldbuilding advice?

No. FanBell's setup does not require a booking history, a GM rating, or a marketplace listing to publish a Creator Service or a Paid Private Question. Selling worldbuilding advice is a standalone offer built on your design judgment.

Can I sell feedback on a fan's homebrew that's set in Forgotten Realms?

You can sell general craft advice — pacing, faction logic, pantheon structure — regardless of the setting it is applied to. You cannot sell a deliverable that incorporates Wizards of the Coast's own copyrighted lore, stat blocks, or maps as Fan Content, because the Fan Content Policy requires Fan Content using its IP to stay free. Separately, SRD 5.1 and SRD 5.2 material is available under CC-BY-4.0 and may be used commercially with attribution (D&D Beyond). D&D Beyond's SRD comparison table lists publishing content that uses the Forgotten Realms as available only through DMsGuild, not under either Creative Commons SRD. This answer is general information, not legal advice.

Should worldbuilding feedback be a Paid Private Question or a Creator Service?

Use a Paid Private Question for a single, text-only design question with no attachment. Use a Creator Service when the fan needs to send a document and get written or recorded feedback back, since only Creator Services support file uploads and audio or video delivery.

What if a request turns out to be a full module instead of advice?

Decline and refund it, or point the fan toward a separate commissioned-writing listing. FanBell's documentation states that a creator can decline and refund any request they do not want to fulfill. Keeping "advice on your world" and "I'll write your world" as separate offers prevents that scope creep.

What does FanBell charge for selling GM advice?

FanBell's how-it-works page states: "It's free to start with no monthly fee. A 12% platform fee applies only when a fan actually pays you.". There is no follower minimum, and Stripe's published rate of "2.9% + $0.30 per successful transaction for domestic cards" applies on top of FanBell's platform fee.
