## The freelancer money stack that actually works

Open Monzo Business first for the £50 (Lite tier is free). Route some client payments and expenses through it to hit the one qualifying purchase fast. Use TopCashback for all tool subscriptions, software, hardware and travel — the £20 bonus lands once you cross £10 tracked (easy with one decent invoice or kit purchase). Put your portfolio or client micro-SaaS on Railway with the $20 credit so you are not burning personal cash on hosting.

## Why these three and not the rest

Revolut £70 goes only to the referrer during the June campaign and has more steps. Most other banking or cashback offers are smaller or harder to qualify for as a sole trader. These three require minimal friction and pay real cash or usable credit.

## Frequently asked questions

### Can a sole trader claim all three bonuses?

Yes. Monzo Business, TopCashback and Railway are three separate companies. Each has its own new-customer rules. You qualify once per programme.

### Is Monzo Business Lite really free forever for freelancers?

Yes. Lite has no monthly fee. Pro (£9/mo) adds accounting integrations and multi-user but you do not need it for the £50 bonus.

### How do I track business spend on TopCashback?

Create a dedicated TopCashback account for business purchases. Many freelancers use it for software (Adobe, Notion), hardware (laptops via Currys/Amazon), and client gifts.

### What about Revolut or Chase for sole traders?

Revolut's £70 is referrer-only during the short June campaign and is e-money. Chase requires larger deposits in some promos. Monzo Business remains the simplest highest two-sided cash for most UK sole traders and directors.

### How do I avoid eligibility traps when stacking bonuses?

Never start a signup for any of these brands before using the referral link. Monzo in particular flags abandoned flows permanently. Open one brand at a time and complete the qualifying action fully before the next.
