How to collect payments after an invoice in the UK

To collect payments after sending an invoice in the UK, you need to ensure the invoice is clear and accurate, send it promptly, follow up with the customer on time, offer easy payment methods, and confirm when payment is received. This article explains why payment collection can be difficult, provides a step-by-step process, includes a realistic example with calculations, highlights common mistakes, and shows how HelloGrowthCRM supports the process.

Why this comes up / what goes wrong

Small business owners often find it hard to collect payments after invoicing because customers delay payment or invoices lack key details. Many send invoices by email or WhatsApp but do not track if the invoice was viewed or paid. Without a clear system, payments get delayed, hurting cash flow. Payment instructions may be unclear or inconvenient, causing confusion. Business owners juggling sales, operations, and admin may forget to follow up or fail to reconcile payments properly.

Step-by-step

1. Prepare and send a clear invoice

• Include your business name, address, contact details, invoice number, invoice date, payment terms, and due date.
• List goods or services clearly with quantities, prices, VAT if applicable, and total amount.
• Specify accepted payment methods (bank transfer, card, cheque, etc.).
• Send the invoice promptly by email or WhatsApp and confirm the customer received it.

1. Track invoice status

• Record when the invoice was sent and the payment due date.
• If possible, confirm the customer has viewed the invoice.

1. Follow up before the due date

• Send a polite reminder about the upcoming payment a few days before the due date.
• Restate payment details and due date.

1. Follow up on and after the due date

• If payment is not received by the due date, send a reminder immediately.
• Follow up again after 7 days if needed, increasing urgency but keeping communication professional.

1. Offer convenient payment options

• Provide clear instructions for payment methods.
• If possible, offer online payment links or bank details.

1. Confirm receipt of payment

• When payment arrives, confirm it promptly with the customer.
• Update your records to mark the invoice as paid.

1. Escalate if necessary

• For payments overdue beyond 30 days, consider sending a formal demand letter.
• Explore mediation or professional debt collection if appropriate.

Example (fictional figures)

A letting agency in Manchester invoices a landlord £3,600 for monthly rent on 01/05/2024, payable within 14 days.

Invoice amount = £3,600

Due date = 01/05/2024 + 14 days = 15/05/2024

Steps:

1. Invoice sent on 01/05/2024 by email including bank transfer details.
2. Reminder sent on 10/05/2024 (5 days before due date).
3. Payment not received by 15/05/2024, reminder sent same day.
4. Payment received on 18/05/2024.
5. Confirmation email sent on 19/05/2024.

Calculations:

Total invoice = £3,600

No VAT assumed for this example.

Payment received = £3,600

Balance due = £3,600 - £3,600 = £0

Common mistakes

• Sending unclear invoices: Always include all payment details and terms to avoid confusion.
• Not tracking invoice status: Keep logs or use tools to know when invoices are sent and viewed.
• Delaying follow-up: Contact customers before and immediately after the due date to prompt payment.
• Limited payment options: Offer bank transfers, card payments or online links to make paying easier.
• Ignoring overdue payments: Act promptly on late payments with reminders and escalation if needed.
• Not confirming payment received: Always notify customers when payment arrives to maintain trust.
