International collaborations are normal now. A composition can start in one country, get finished in another, and end up moving through multiple collecting societies, with writers, publishers, and administrators spread across different territories. The creative side often moves fast. The part that usually causes trouble comes later: organizing the work properly, registering the composition cleanly, and making sure the royalty side does not get slowed down by avoidable mistakes.
That is where things tend to break down. A split that is remembered differently by each writer. A name spelled one way in one system and another way elsewhere. A co-writer who has not joined a society yet and still does not have an IPI. A split sheet that was never finalized. A work that gets uploaded before the information around it is actually stable.
This article is about cleaning that up. We are going to walk through what is actually being registered, what the main terms mean, what information you need before release, what to do if one of the writers still does not have an IPI, and how to leave the composition in much better shape for international royalty collection.
If you want the broader foundation first, including copyright, PROs, IPI, ISWC, and ISRC, read this companion guide on se7en beatlab.
What you are registering when you talk about a composition
This article is about the musical composition, meaning the written work itself: melody, harmony, lyrics, and song structure. That is the layer that gets registered so the writers and composers behind the song can be identified and paid correctly.
There is also the sound recording, meaning the master that gets distributed through platforms and releases. The composition and the recording are connected, but they are not the same asset. One composition can sit underneath several recordings: the original version, an acoustic version, a remix, an instrumental, a radio edit. Keeping those layers separate from the start saves a lot of confusion later.
What the main terms actually mean
PRO or collecting society
A PRO, or performing rights organization, is a collecting body that administers certain rights and helps collect and distribute royalties when music is used publicly. Depending on the territory, you will also see the broader term collecting society. That includes names such as ASCAP, BMI, PRS for Music, GEMA, SOCAN, SACM, SADAIC, and SGAE. They all operate within the same world, but they do not all follow the same process.
IPI
An IPI is the international identifier attached to a writer, composer, or publisher inside the collecting society system. It helps societies tell one person apart from another and makes international matching much cleaner. In cross-border co-writing situations, it is one of the most important pieces of data you can have.
ISWC
An ISWC is the international code that identifies the musical composition. It belongs to the song as a written work, not to the master recording.
ISRC
An ISRC identifies a specific recording. Every recorded version can have its own ISRC even when the underlying composition is the same.
Splits
Splits are the ownership percentages assigned to each writer or composer on the work. If two people wrote a song equally, the splits might be 50/50. If four people were involved, the percentages may be different for each person.
Split sheet
A split sheet is the document that records that agreement. It usually includes the song title, the writers involved, their roles, their societies, their IPI numbers if available, and the exact percentages agreed between them.
Publisher
A publisher or publishing administrator handles certain rights connected to the composition. Not every song has a publisher attached, but when publishing is part of the picture, it needs to be reflected early because it affects registration, administration, and royalty tracking.
What should be settled before the song comes out
Before releasing a song with co-writers in different countries, it helps to lock down the core information around the composition:
- the final title of the work;
- the legal names of all writers;
- artist names or aliases if relevant;
- the society affiliation of each party;
- each writer’s IPI, if they already have one;
- the actual role of each person in the work;
- the exact split percentages;
- whether there is a publisher or administrator involved;
- a finished split sheet signed or confirmed by everyone;
- one reliable source of truth for all the metadata.
When that foundation is strong, the registration side becomes much easier. When it is loose, problems tend to show up later, usually when the song is already moving.
What if one of the co-writers does not have an IPI yet?
This happens all the time. The composition is finished, the percentages are agreed, but one of the writers has not joined a collecting society yet, so there is no IPI attached to that person.
That does not mean the rest of the song has to sit in limbo. The writers who do have their information in place can still organize the work properly. The important thing is that the split sheet still includes the writer who does not have an IPI yet, using that person’s correct legal name, actual role in the song, and agreed percentage.
What matters here is understanding the limitation. Without an IPI, that share of the composition is harder to trace cleanly across societies. The work can still be documented and prepared properly, but that writer’s identification inside the international system is less robust until the affiliation is completed.
The practical way to handle it is simple:
- settle the splits in writing;
- store the full metadata for every writer;
- register the writers who are already properly affiliated;
- keep the non-affiliated co-writer clearly identified on the paperwork;
- help that writer complete the affiliation as soon as possible.
In other words, the composition can still be organized correctly from day one, but the cleanest long-term position is for every co-writer to end up properly identified inside the system.
The smartest habit: keep one source of truth for the metadata
One of the best ways to avoid international registration problems is to treat the composition like a data workflow, not just a creative memory. That means keeping one reliable document with the core information: title, language, creation date, legal names, artist names, roles, percentages, societies, IPIs, publishing details, and any recording references that matter.
That source of truth can live in a spreadsheet, Notion, Airtable, or whatever system fits your workflow. The tool is not the important part. The important part is that there is one stable version everyone can work from. When the producer has one version, the topliner has another, and the publisher has a third, it becomes much easier for mistakes to spread.
How to register an international composition step by step
The most solid workflow is fairly straightforward:
1. Identify who actually owns the composition
Work out who wrote the song, who composed the music, and whether there is any publishing or administration attached.
2. Gather the identity data for each party
That includes legal name, artist name if relevant, society, IPI, role, and split percentage.
3. Settle the splits properly
Every percentage should be clear and the total should make sense before anything goes live.
4. Finalize the split sheet
This is where the agreement stops being verbal and becomes part of the working record.
5. Build the metadata file
Keep the composition data in one place so the information stays consistent when it reaches registration portals, publishers, managers, and co-writers.
6. Register the composition with the relevant society
This is where the society rules, the writer affiliations, and the publishing setup start to matter.
7. Check that the registration landed correctly
After filing, review the catalogue entry, the names, the percentages, the identifiers, and any publisher information that should be attached.
8. Keep track of the work after registration
Once the song starts being used, you still need to monitor whether the work is being identified properly and whether additional reporting is needed.
Why different societies can change the workflow
Collecting societies work together internationally, but they do not all operate the same way. Some allow one filing to include foreign co-writers quite smoothly. Others require extra confirmations. Others are slower in certain international payment cycles or more formal about approvals and claims.
That is why there is no single universal form that solves everything in every country. The consistent part is the preparation: the cleaner the composition data is before it reaches the system, the fewer problems it tends to create later.
The mistakes that delay money the most
The same issues come up again and again:
- splits that were never properly finalized;
- names entered differently across systems;
- incorrect IPI numbers;
- missing writers;
- publishers not declared;
- the same composition uploaded under different titles;
- unfinished split sheets;
- no verification after registration.
These problems are easy to miss at first. They often show up later, when the song is already out, when a catalogue entry looks wrong, or when a payment fails to arrive the way it should.
Registration is only part of the job
Once the composition is registered, it still needs to be checked. The work should appear correctly in the repertoire. The co-writers should be listed properly. The percentages should match the actual agreement. Any publisher information should be in the right place. Where relevant, the ISWC should eventually be visible too.
A composition is not really finished on the admin side when you hit submit. It is finished when the information around it is stable enough to move cleanly through the system.
Why international royalties take time
International royalty payments usually move much more slowly than the writing and release process. A composition used in another territory has to be identified, processed, matched, passed through society systems, and eventually paid out. That means a song can be registered correctly and still take time before foreign income appears.
That delay does not automatically mean something is wrong. The important part is knowing the difference between normal payment timing and a delay caused by messy data.
What to check if the composition is registered but money is not showing up
If the work appears in the repertoire but the money is not landing, review the basics carefully:
- are the writers identified correctly?
- do the percentages match the agreement?
- are the IPI numbers accurate?
- is there missing publisher information?
- is the composition sitting under the correct title?
- did any uses require separate reporting or claims?
In a lot of cases, the issue is not that the entire registration failed. It is that one weak piece of information stopped the work from being matched cleanly.
Conclusion
Registering a musical composition with co-writers in different countries takes more than a good song. It takes clean information, clear percentages, stable documentation, and enough discipline to treat the work like an asset once it leaves the writing session.
When the names are right, the splits are settled, the IPI numbers are checked, and the metadata lives in one reliable place, the whole system has a much better chance of doing its job. The composition becomes easier to identify, easier to administer, and easier to pay correctly.
