Apple Developer Program

• About US$99 per year (check current price) — individual or organisation
• Organisations need a D-U-N-S number; the legal name and address must match it exactly
• Enrol with the Apple ID of someone authorised to sign for the company; verification can take days

Google Play Console

• One-off US$25 registration fee
• Organisation accounts need identity and organisation verification, a D-U-N-S number for new organisation accounts, and a contact address and phone
• New personal accounts must complete closed testing with testers before production release — check the current policy

Keep all logins, recovery codes and signing keys in your company password vault, not on one person's laptop.
