Refer us.
Earn with us.
If you know a lot of people, a referral can be a simple way to earn extra. You put us in touch with someone who needs a website, design, video or an app, and we handle the deal and the work. Earnings are not guaranteed.
What you can refer people to.
BIRO 404 is a digital studio from Serbia. We work with companies and entrepreneurs. You do not need to know how any of this is made, only who might need it.
So people find the business
Websites, online shops, Google Business Profile, SEO, social media
A business with no website, a website that brings no enquiries, or one people cannot find on Google.
So people remember the business
Visual identity, logo, graphic design, video
A business that is just starting, changing its look or coming across as weaker than it is.
So the work runs more easily
Business apps, automation, AI assistants
A business that does the same work by hand every day and loses enquiries, appointments or orders in messages and spreadsheets.
How you earn.
- 01Get in touchBy message or phone. We get to know each other briefly and write down the terms.
- 02Send a referralBy WhatsApp or email, send the business name, their contact details and what they need, once that person agrees to be contacted.
- 03We run the jobWe talk to the client, send a quote, do the work and collect payment.
- 04You get your commissionOnce the job is agreed, completed and paid for, we pay you the agreed amount.
Your part
You know people, spot an opportunity and put us in touch. You do not provide our services yourself: no coding, no design, no quotes and no project management.
Our part
The conversation, quote, contract, work, payment and responsibility for the job.
How commission works.
- How much
- 20% on most of our services. We list the services it does not cover in the written agreement.
- Example
- The client pays €1,000 and your commission is €200. The example is illustrative, and €1,000 is not a fixed price.
- When
- After the client has paid. The payment deadline and method go into the written agreement.
- When there is no commission
- If the client does not accept the quote or the job is not paid for.
Earnings are not guaranteed. The result depends on how many referrals become paid work.
How you follow a referral.
We tell you when something changes: when we talk to the client, send a quote, agree the job, collect payment or when the client drops out.
The partner space is a separate system for accepted partners and it is not open yet. When it opens, you will send referrals and see their status there, and short Academy lessons will show what each service does and who it helps.

Biljana MilovanovićCommon questions.
Does it cost anything?
No. You pay nothing to refer us.
Is this a job?
No. You refer when you have someone, with no working hours and no obligation to send a set number of referrals.
How much can I earn?
That depends on the value of the job and on how many referrals become paid work. The example is at the top of the page. We do not guarantee earnings.
Do I need to have a company?
Tell us in the first conversation and we will sort it out before the written agreement.
Start with one message.
Tell us you are interested. We get to know each other briefly and agree the terms. A first conversation commits neither of us.
