Your Recommended Service
View Recommended PackageUnderstanding Your Transaction Count: Marketplaces vs. Bank Entries
We count the single total amount that appears on your bank statement, not every single sale, refund, or fee on the marketplace's own statement. This approach drastically reduces your costs.
| Your Activity (Marketplace/Platform) | Counts as |
|---|---|
| You make 250 sales on eBay or Etsy over a two-week period. Your bank account shows a single bi-weekly deposit from the marketplace (e.g., eBay, Etsy, Amazon). |
1 Transaction |
| You process 100 credit card payments for your shop, settled daily by a provider like Stripe or Square. Your bank account shows 30 daily deposits (one for each day of the month). |
30 Transactions |
| You process 100 cash sales through your till and provide a Z Total for each day You deposit the entire day's takings in one go, and give 1 daily figure from your Z Total |
1 Transaction |
| You pay 3 monthly utility bills (electric, internet, water) via separate Direct Debits. Your bank account shows 3 separate withdrawals. |
3 Transactions |
| You withdraw cash 5 times from an ATM for petty cash expenses. Your bank account shows 5 separate withdrawals. |
5 Transactions |
In short: A single lump sum payment received in your bank account—which includes many sales and has already had fees/VAT deducted—is treated as one consolidated transaction for your package.
