Good input

What your CSV should include.

Export an aged-debtors list from Xero, QuickBooks, Sage, or your workbook. The file only needs enough detail to identify the customer, invoice, due date, and amount owed. SHVL recognises common accounting-export labels such as Contact, Invoice Number, Due Date, Due, and Open Balance. If an email address is present, SHVL fills the draft recipient; if not, the draft opens with a blank To field.

customer email invoice_number due_date outstanding

Optional columns such as contact name, purchase order, notes, or previous chase date are useful, but not required for the first validation pack. If you are starting from scratch, use the aged-debtors CSV template, run the aged-debtors health check, or download the sample chase pack before checkout.

Calculation method

How the numbers are checked.

SHVL uses the invoice amount, due date, and current calculation date to estimate statutory interest at 8% over the relevant Bank of England base rate. It also applies the Schedule 6 fixed compensation band: £40 under £1,000, £70 from £1,000 to £9,999.99, and £100 from £10,000.

The pack is a calculation and drafting aid for commercial debts. If a debt is disputed, consumer-related, contract-specific, or legally sensitive, take advice before using any draft.

Before you upload

What you should know.

Who can claim statutory interest?

UK businesses claiming from other UK businesses. The Late Payment of Commercial Debts (Interest) Act 1998 covers business-to-business debts only; it does not apply to debts owed by consumers.

What are the £40 / £70 / £100 fixed sums?

Schedule 6 of the Act sets a fixed compensation per overdue invoice: £40 for debts under £1,000, £70 for debts £1,000 to £9,999.99, and £100 for debts of £10,000 or more. These are owed in addition to statutory interest.

When should I not use a chase pack?

Consumer debts, debts already in formal dispute, debts where the contract sets a higher interest rate you wish to apply instead, and debts where you have already agreed in writing to waive these rights.

What happens after I upload?

After checkout, the page generates a ZIP containing three escalating digital letter drafts per debt, openable email drafts, and a calculation workbook. Nothing is posted, emailed, or sent to a debtor automatically.
