The client's review screen for the song Glasshouse, mix version 2: a waveform with five note markers above it, the played part in blue, and the notes listed with their timecodes, such as 02:00.400, snare fill lost under the guitars.

Fig. 1, your client's screenGlasshouse, mix V2

  1. Versions. V1 and V2 sit one click apart, matched in level.
  2. Notes. Each note is pinned to the second it describes.
  3. Replies. You answer under each note and tick it off when it is done.
  4. Approval. One button records the version your client signed off.
The studio's dashboard: active projects, clients, versions and storage used, and what needs attention, such as a client saying an invoice is paid.

01Why switch

Run your studio like a business.

Every client works with you the same clear way, from the agreement to the final files.

  • Clear terms up front

    Clients sign your agreement before the first upload. Your price and your revision rounds are on record for both of you.

  • Notes you can act on

    Clients click the waveform and type. Every note arrives with its exact time, such as "02:00, snare fill lost under the guitars".

  • Paid before the finals leave

    Each invoice carries your own payment page. The final files stay locked until you are paid, and the money goes straight to you.

  • Every job runs the same way

    Mix, notes, revisions, approval, payment, delivery. The approval names the exact version your client signed off, so nothing is left in doubt.

02The product

Every screen here is the real product.

The pictures show the software running a sample studio with sample songs.

The review screen on a phone: version buttons V1 and V2, an Approve button, the waveform with note markers, and the transport.

2.1Review

Notes land on the exact second.

Your client taps the waveform and types, on a phone or a laptop. You read each note where the problem is, reply under it and tick it off. Anything still open moves with the song to the next version.

The A/B bar above the waveform: version A is V2, version B is V1, a Switch button, and Match loudness switched on.
A/BV2 against V1, level-matched

2.2Versions

The A/B is level-matched.

V2 goes up next to V1. Your client switches between them at the same moment in the song, at matched loudness, so the comparison is fair. When they are happy, they approve that version.

A mixing agreement in the portal: the studio's terms, a box ticked for signing electronically, the client's typed name and a Sign button.
ContractSigned before the first upload

2.3Contracts

Clients sign your terms before you start.

Write your agreement once, or use your own PDF. Clients sign it before the first upload, and both of you receive the signed copy by email.

The client's Payments tab: a deposit marked Paid, and the balance awaiting payment with a Pay now button, an I've paid button and the studio's own payment instructions.
Payments"Pay now" opens the studio's own payment page

2.4Getting paid

Clients pay you directly.

Invoices sit inside the project, and "Pay now" opens your own Stripe, PayPal, Square or Venmo page. The money goes straight to you, and we take nothing from it. Deposits and payment plans are ready when a job needs them.

07Questions

Every question gets a straight answer.

Do my clients need an account or a password?

No. They open the email you send them and they are in, on any phone or computer. There is no app to install and no password to remember.

Do my clients pay anything?

No. Clients are free and unlimited on every plan, and so are guests.

Do you take a cut of my payments?

No. Clients pay you through your own Stripe, PayPal, Square or Venmo page, so the money goes straight to you. You pay us a flat plan price and nothing more.

Which plan is right for me?

Each plan is described in the table above.

Every plan has the whole review process, and your clients never pay anything on any plan. You can move up or down at any time.

What happens after the trial?

When the 30 days are up, the plan you chose starts and your card is charged for it. We email you 7 days before. Cancel before then and nothing is ever charged: your studio becomes read-only when the trial ends, and you and your clients can still sign in, listen and download.

Everything stays for $OVER_DAYS days, and we email you $NOTICES. If no plan is chosen by then, the audio of your projects is removed, finished projects first. Notes, approvals, contracts, invoices and messages are always kept, so they are all still there when you choose a plan.

Can I cancel?

Yes, at any time, in one click under Plan and billing. Cancel during the trial and nothing is ever charged. A paid plan runs to the end of the period you paid for, and then your studio becomes read-only. Nothing is deleted at that point.

Everything stays for $OVER_DAYS days after that. If no plan is chosen by then, the audio of your projects is removed, finished projects first; notes, approvals, contracts, invoices and messages are always kept. Moving to a smaller plan works the same way: if your studio holds more than the new plan allows, you have $OVER_DAYS days to make room before the oldest finished audio is removed.

Who owns my files and my client list?

You do. You can download your projects, notes, invoices and client list whenever you like, and every audio file downloads from its project.

Is my work private?

Yes. Each studio is kept apart from every other, and each client sees only their own projects. We do not sell data and we do not show ads.

Can anyone else open my clients' mixes?

Only the people you choose. Every client signs in with their own link. A guest link you share plays previews only, can have a password, and always expires. You can switch any link off at any time.

Can I use my own logo and my own web address?

Are online contracts legally binding?

In general, yes. Electronic signatures are valid for this kind of agreement in the US, the UK and the EU, and each signature is kept with a record of who signed and when. This is general information and is no substitute for legal advice.

What if my client is not technical?

Most clients are not. Anyone who can open an email and press play can leave a note, and a short guide shows them how the first time.

Run your next session from your own portal.

Setting up takes a few minutes. Your first client could be listening tonight.
