Your typical monthly eBay revenue?
A rough idea is fine.
- Video call, 30 minutes. Bring your Managed Payments dashboard or just share your screen.
- No eBay login needed - you drive, I read and annotate.
- You leave with a written note of what I'd reclaim and which Promoted Listings are loss-making, whether or not we ever work together.
Selling as a sole trader? MTD quarterly updates are now mandatory over £50K, and your first quarterly deadline is 7 August 2026. Worth sorting before then.
After years inside eBay sellers' books, here's where the money leaks.
Figures below are illustrative and typical for a seller doing around £400K on Managed Payments. Your numbers will be different.
We do this diagnostic live, free, 30 minutes.

If you've read this far...
I'm Harvey, I run Zmartly's eBay practice for UK sellers doing £100K to £2M a year. After years inside eBay sellers' books, four problems show up every time: Managed Payments holds booked as income in the wrong period, VAT on Final Value Fees never reclaimed, Promoted Listings ROI left untracked, and EU sales running without an OSS registration. Book the free 30-minute Tax Health Check and I'll open your Managed Payments dashboard live on the call - no login needed from you, no pitch. You leave knowing exactly what I'd reclaim and what you'd pay.
You're probably tired of eBay income arriving as a single net figure that nobody on your current team can unpick. Book 30 minutes with me. I'll open your Managed Payments dashboard live on the call and tell you what I'd reclaim and what you'd pay. No pitch. If we're not the right fit, I'll say so.
P.S. The 30 minutes is genuinely free and genuinely useful. Some sellers take the diagnostic and stay with their current accountant. Either way, you leave knowing exactly where your eBay numbers stand.

What everyone asks me on the call:
Yes. We connect to your Managed Payments account and reconcile every settlement: holds, reserves, Final Value Fees, Promoted Listings spend, INR/SNAD refunds and reimbursements are all categorised separately so your P&L matches what eBay actually paid you, not the gross number.
Sellers doing £250K+ a year on eBay typically miss £2,000-£6,000 of reclaimable input VAT annually because their accountant never separates the VAT element of Final Value Fees. We identify every recoverable amount and claim it on your next VAT return. Individual results vary.
No. Many sellers start with the free Tax Health Check while still with their current accountant. If you decide to switch, we handle the entire professional clearance, write to them, transfer records and set up Xero. Your part takes less than ten minutes.
Four things: a Final Value Fee VAT scan to surface missed input VAT; a live Managed Payments walkthrough to separate holds and reversals from actual income; a Promoted Listings ROI check to identify loss-making campaigns; and a deadline and structure review to confirm your VAT, Self Assessment and Corporation Tax positions.
No. You share your screen on the call. I walk through your Managed Payments dashboard and Seller Hub with you rather than logging in independently. You keep full control of your account at all times.
UK VAT, Self Assessment, Corporation Tax and accounts are fully in scope. If your EU sales are running without an OSS or IOSS registration we will identify the exposure on the call and tell you straight what needs fixing and who handles what. No vague promises: you leave knowing exactly where your obligations lie.
We handle multi-channel sellers regularly. Each channel is reconciled separately, eBay Managed Payments settlements, Amazon Seller Central payouts, and any other platforms, then consolidated into a single P&L so you can see which channel is genuinely profitable.
MTD for Income Tax Self Assessment went live in April 2026 for sole traders and landlords earning over £50,000. If you are self-employed and over the threshold, quarterly digital submissions to HMRC are now mandatory. We handle all MTD submissions through Xero so you never miss a deadline.
We handle late filings, HMRC correspondence and enquiries regularly. We will assess the position in your free Tax Health Check, advise on the best course of action and communicate with HMRC on your behalf. Acting early almost always reduces penalties.
