VAT payments as a non-Uk resident

Amazon is currently deducting 20% VAT on each sale, and I’m wondering if it’s possible to pay this VAT directly to the UK government every three months instead. After paying 20% to Amazon and another 20% to my supplier, I’m operating at a loss, and it’s really affecting my cash flow. My investment is small, and since VAT returns are quarterly, it’s tough to manage.

I’m not a UK resident, so if anyone else has faced this issue, could you please share how you handled it?

Any advice would be greatly appreciated.
