Software licensing
Software income is licence income: the user never owns the code, only a permission to run it on defined terms. The metric that defines the permission — seats, cores, devices, calls, revenue — is what turns usage into money, and it is chosen before anything is priced.
Start here if the word royalty is all you know: somebody uses something you own, and a slice of what they earn from that use is sent to you. Everything on this page is a description of who counts the uses, who writes the cheque, when it arrives and what makes it shrink. What would mislead: assuming one royalty is like another. The rules below apply to this type only, and the money can arrive months after the use that earned it.
How the payment is calculated
Direct licensing is priced against a metric. Per-seat and per-user pricing counts people; per-device and per-core counts machines; subscription pricing bundles the licence with support and updates; metered or usage pricing counts calls, transactions or compute. A perpetual licence with an annual maintenance fee separates the right to run from the right to keep receiving updates, and the maintenance stream is often worth more over time than the original licence.
Embedded and OEM licensing pays a royalty to the code's owner each time the licensee ships a product containing it, computed per unit or as a percentage of the licensee's price. This is the arrangement that most resembles a classic royalty.
App stores and platform marketplaces take a published commission and remit the rest. The commission, the small-developer tiers and the payout schedule are set unilaterally by the platform and have been changed by litigation and regulation; read the current terms on the platform's own developer site rather than relying on a figure quoted anywhere else.
Dual licensing offers the same code under an open-source licence and under a commercial one, and the income comes from users whose own products cannot accept the open-source obligations. What the open-source licence requires — attribution, source disclosure, copyleft reaching into derived works — is the entire commercial leverage.
How often it arrives
Subscriptions bill monthly or annually in advance. Perpetual licences pay once with maintenance renewing annually. Store payouts run monthly, in arrears, after a holdback period.
OEM and embedded royalties are reported on the licensee's schedule, usually quarterly, and are trued up by audit. Licence compliance audits are a routine part of enterprise software and a material source of revenue for the vendor.
What erodes it
Every royalty shrinks. What differs is the mechanism and the speed.
This is the section that separates a royalty from a bond. Nobody promised you a number: the payment follows how much use there is, and use fades. A song is played less, a patent expires, a well produces less every year it runs. Where this misleads: reading last year's payment as a run rate. The honest question is not what it paid, but how many years of paying are left and at what level.
Churn
Subscription income is only as durable as renewal. Seats shrink with the customer's headcount, and a metric tied to something the customer controls is a metric the customer will optimise.
Maintenance decay
Perpetual licensees stop paying maintenance when updates stop mattering to them, and the stream ends without the licence ending.
Platform terms
For store-distributed software, the commission, the ranking, the policies and the eligibility rules are set by a counterparty with no obligation to keep them stable.
Open-source substitution
A capable free alternative caps price for everyone in the category, and arrives without warning.
Support obligations
Licence income usually comes attached to service-level commitments, security patching and compatibility work. The revenue is passive; the obligations are not.
Compliance drift
Under-deployment reporting by licensees is common and is corrected by audit, which is an adversarial process with legal cost attached.
What diligence looks like
Diligence on a royalty is mostly document work: proving the right exists, proving the seller owns it, and proving the payments you were shown came from it. The easy mistake: a statement showing money arriving. A statement proves that a payment was made, not that the right behind it is unencumbered, correctly registered, or yours after the sale.
- Identify the licensing metric and who controls the number it counts.
- Separate licence revenue from maintenance, support and services revenue; they have different durability.
- Read the audit and true-up clause, including notice, frequency and who pays.
- Check the open-source inventory of the codebase and the obligations that come with each component.
- Confirm ownership of the code: contractor assignments, employee agreements and any code contributed by third parties.
- For store-distributed software, read the platform's current developer agreement and payout terms.
- Check escrow arrangements, assignment restrictions and change-of-control clauses in enterprise agreements.
Tax treatment
Whether a payment is a royalty, a service fee or a sale of goods matters for sourcing and withholding, and software payments regularly fall in different categories under different countries' rules.
US developers generally report software licence income as business income on Schedule C or through their entity; a passive holder of an OEM royalty stream is closer to Schedule E treatment.
Cross-border licence payments attract withholding tax that treaties often reduce, and several jurisdictions treat software payments as royalties where the US does not — a mismatch that shows up as unexpected deductions on foreign remittances.
Where interests like this change hands
Royalty Exchange
Music and IP
- What trades there
- Music royalty streams above all — a songwriter's share, a publisher's share, master recording income, sometimes a whole small catalogue. Other IP streams (film, book, patent) appear from time to time.
- How the sale works
- Listed sale. Each offering is published with historical earnings statements attached, then sold by a timed online auction or as a fixed listing; larger catalogues are sometimes handled as a negotiated private sale off the public board.
- Typical buyer
- Individual investors and small funds buying an income stream outright, plus catalogue acquirers using it as deal flow.
SongVest
Music and IP
- What trades there
- Music royalties, sold both as whole streams and as fractional interests in a single song or a small group of songs.
- How the sale works
- Two routes. Fractional interests are offered to the public through a registered or exempt securities offering with its own disclosure document; whole-stream sales are negotiated between seller and buyer.
- Typical buyer
- Retail buyers and fans at the fractional end; catalogue investors at the whole-stream end.
Sedo
Music and IP
- What trades there
- Domain names — outright sale, lease-to-own and parking.
- How the sale works
- Marketplace listing at a fixed price or make-offer, with brokered sales for larger names. Transfer and payment run through the platform's own escrow.
- Typical buyer
- Businesses buying the exact name they want, plus domain investors.
Afternic
Music and IP
- What trades there
- Domain names, sold and leased through a distribution network that surfaces the listing inside registrar search results.
- How the sale works
- Fixed-price 'buy it now' and offer/counter-offer, settled by the platform; instalment and lease-to-own plans hold the name in the platform's control until the last payment clears.
- Typical buyer
- End-user businesses, and investors buying inventory.
These are the visible venues. Most mineral and royalty interests never touch one. They move through a broker or a landman working a specific county, through an unsolicited offer letter mailed to an owner whose name appears in the county deed records, through an operator buying up the royalty under its own wells, and through probate when an estate is settled. County records are the real order book: ownership, leases, assignments and prior sale prices are filed at the courthouse where the land sits. Music is the same story one level up — the marketplaces are the retail end, and most catalogue value trades in privately negotiated deals brokered by specialist advisers. A price you see on a public venue is not a market quote for anything else.
