FAQs

Frequently asked questions

I sell on Amazon, eBay, Etsy and TikTok Shop. How do you keep the books straight?

Marketplaces pay out in lump sums after deducting fees, refunds, advertising and reserves, so the amount in the bank rarely matches what you sold. We connect each channel to your accounting software and record sales, fees, refunds and VAT separately, so you can see the true margin on every channel and product.

Do online marketplaces report my sales to HMRC?

Yes. Platforms that pay sellers collect their details and earnings and report them to HMRC every year, and HMRC compares the figures with your returns. Marketplaces are also taking a growing part in collecting VAT on the sales made through them. We make sure your accounts, your returns and the platforms’ statements tell the same story.

When do I need to register for VAT?

When your taxable UK sales pass the VAT registration threshold in any rolling 12 months, or you expect them to within the next 30 days. The test runs every month, not once a year, so growing sellers can cross it without noticing. Selling from overseas stock or to customers abroad brings further rules, and we set up whatever your channels need.

How do we know which products really make money?

By counting every cost of a sale against it, including the product itself, platform and payment fees, postage and packaging, returns and advertising. Many sellers find their best-selling lines earn the least once those are included. We report margin by product and channel each month, so you can price, promote or drop lines with confidence.

How should I value my stock?

At the lower of what it cost you and what you can realistically sell it for. Slow-moving, damaged or discontinued lines should be written down, not left in at cost. An accurate year-end stock figure is what makes your gross margin, and your tax bill, right.
