Marginal VAT Filing Assistance

I run a retail business and it’s time for my next marginal VAT return. Everything is recorded in simple spreadsheets and bank statements—no QuickBooks, Xero, or other software in place—so I need someone who can work comfortably without an automated feed and still produce an accurate submission. Here’s what I expect: • Review my raw sales and purchase data (CSV, PDF receipts, paper invoices scanned to PDF). • Calculate the margin scheme figures correctly, • Complete the VAT return form ready for me to sign and submit, with a short note explaining the calculations so I can understand how the numbers were reached. If you have solid UK retail VAT experience, especially with margin schemes, and can turn this around quickly, I’d like to hear from you.
