Credit control and debt-recovery guidance

Free tools for managing overdue business invoices

Late payment rarely begins with a single isolated event. Effective credit control starts before supply, continues through accurate invoicing and consistent payment reminders, and moves into structured recovery when an overdue balance remains unresolved.

The Rezolva business tools support each part of that journey. Use them individually to solve an immediate problem or together to review your process, chase payment, understand the commercial position and decide what to do next.

Frequently asked questions

Rezolva business tools FAQs

Are the Rezolva business tools free?

Yes. The tools on this page are free to use and carry no obligation to instruct Rezolva. They are designed to provide practical guidance and help UK businesses make informed credit-control and debt-recovery decisions.

Do I need a Rezolva account to use the tools?

No. You can use the tools without creating a Rezolva account unless a particular result offers an optional email or account feature. An account is only needed if you choose to access Rezolva's client platform or place a debt.

Which tool should I use first?

Use the Credit Control Health Check to review your wider order-to-cash process. If you are dealing with a particular unpaid account, use the Commercial Debt Recoverability Assessment. If you are ready to send one final email before escalation, use the Invoice Chaser Email Generator.

Can the invoice tools be used for several invoices?

Yes. The Invoice Chaser Email Generator can describe a total account balance made up of several invoices, while the late-payment calculation should be checked against the relevant invoice balances and payment dates.

Do the tools provide legal advice?

No. They provide general business information based on the details entered. They cannot assess every contractual term, item of evidence, dispute, jurisdiction or limitation issue. Obtain professional advice where the legal position is uncertain or contested.

What should I do if the customer still does not pay?

Gather the contract, invoices, statements, delivery evidence and correspondence. Use the recoverability assessment to review the commercial position, then consider placing the account with Rezolva for professional debt resolution.
