Commission mechanics — how Earnr payments work
The 2-year per-referral clock
Day 0 — Your friend signs up
Their 2-year commission clock starts. This is independent of when you became an Earnr.
Day 30 — Trial ends, they subscribe
Commission begins accruing from their first paid month. Paid to you monthly.
Month 12 — Year 1 pro
You've earned £42 (at blended avg £35/mo × 10%) from this one referral.
Month 24 — Commission window closes
Commission stops on this referral. Total earned: £84 over 2 years (blended avg). New referrals each have their own 2-year window.
Month 25+ — Customer stays with £arnd
They continue as a customer but commission no longer applies (unless Affiliate Earnr tier).
Commission per subscription tier

Core£15£1.50£18£36
Plus£40£4.00£48£96
Pro£55£5.50£66£132
Blended avg~£35£3.50£42£84
Commission adjusts automatically if a referred customer changes tier. If they upgrade from Core to Plus, your monthly commission increases from £1.50 to £4.00 from that month forward.
The retroactive lump sum — explained
💡
When you make your 5th referral and become an Earnr, £arnd calculates how much commission you would have earned on referrals 1–4 from their signup date to today — and pays it as a one-off lump sum.

Example: Referrals 1–4 each signed up 3 months ago at Plus (£40/mo).
Lump sum = 4 clients × 3 months × £4.00 = £48

The earlier your referrals signed up, the larger the lump sum.
Earnings projections — Customer vs Earnr at 5, 10, 20, 50 and 100 referrals
Earnings shown at three subscription mix scenarios: All Core (£15/mo) · All Plus (£40/mo) · All Pro (£55/mo) · Blended average (~£35/mo). Commission figures apply to Earnr tier only. Customer tier earns free months — not cash.

* Customer tier value calculated at Plus £40/mo. 2-year total assumes all referrals sign up at the same time and stay on the same plan for the full 2 years. Real earnings will vary as customers change tier. Commission adjusts monthly based on each customer's active plan.

Staying as Earnr

Commission only flows from active subscribers. If a referred customer cancels, their commission stops. It resumes if they resubscribe (within the 2-year window).

Commission expiry rules
2-year window — per referral, not per tier upgrade
Each referred customer has their own independent 2-year clock starting from their signup date. Becoming an Earnr later does not reset or shorten anyone's clock.
Referred customer cancels subscription
Commission pauses. If they resubscribe within the 2-year window, commission resumes for the remaining time.
Referred customer downgrades tier
Commission reduces to reflect the lower tier value. Adjusts in the next monthly payment cycle.
Referred customer upgrades tier
Commission increases to reflect the higher tier value from that month onward.
After 2 years — commission ends on that referral
Customer continues with £arnd but commission is no longer generated. New referrals made after this point start fresh 2-year windows.

What counts as a valid referral?
Friend signs up via your unique link or QR code, pros the 30-day trial, and starts a paid subscription.
Trial sign-ups that don't convert to a paid plan do not count toward your referral total or commission.

Upgrade path & plan changes
Moving between sole trader plans
Upgrade or downgrade at any time from Settings → Subscription or by tapping a locked feature.

Upgrading — new features unlock immediately. Billing adjusts pro-rata for the remainder of the current month.

Downgrading — takes effect at the next billing date. Features from the higher tier remain active until then. Locked features show blur overlay from billing date.
Moving to Partner
Contact £arnd to set up a Partner account. We'll configure the business account and add each partner's individual profile.

Partners can be added or removed at any time. The +£20/month per-partner charge adjusts in the next billing cycle.

Existing sole trader data can be migrated to the Partner account — nothing is lost.
Moving to Limited
Register your interest and a £arnd advisor will be in touch to discuss your company's requirements.

A fixed monthly fee is agreed upfront — no hourly rates, no surprises. Scope is documented and signed off before billing begins.

Coming soon — register interest via the app or at earnd.uk/limited
Important notes
📅
Annual billing saves 10% — that's 11 months charged, 12 months access. The subscription clock starts at trial end, not at the end of the first free month. Applies to all sole trader plans and the per-partner add-on.
Partner tier regulatory note — self-employed partners (not Ltd companies) file an SA800 Partner Return plus individual SA100s for each partner. £arnd handles all of these. This is separate from a Limited Liability Partner (LLP) — contact us for LLP requirements.
🏢
Limited tier scope — pricing is indicative and starts from £200/month for a straightforward owner-managed company. Companies with employees, multiple directors, complex VAT arrangements or group structures will be priced individually. All prices include £arnd agent authorisation with HMRC.
