Recovering Unpaid Invoices for IT & Software Services

IT and software work is often disputed at the point of payment rather than refused outright. A client may claim a feature was out of scope, that a milestone was never accepted, that an SLA was breached, or that the system was never properly handed over. Time-and-materials billing, change requests and managed-service retainers all add friction. The invoice is real, but the paper trail proving delivery is scattered across project tools, email, ticketing systems and chat.

The pattern is familiar: a project finishes, a final invoice goes out, and the client goes quiet or raises a late objection. Recovery rarely fails for lack of a valid debt — it stalls because the supplier cannot quickly assemble proof that the agreed work was scoped, delivered, accepted and handed over.

The strongest position is one where every billed item maps to a record. For IT and software services, the evidence that matters most usually falls into these categories:

You do not need every item for every claim. The goal is a coherent chain: the SOW or order set the scope, the tickets and timesheets show the work, the acceptance and handover records show the client received and signed off on it, and the invoice reflects all of that. WolfX gives you an Evidence Vault to store and reference these records against each overdue invoice so the chain is ready when you need it.

WolfX organises the recovery workflow around the evidence. You attach the relevant SOW, acceptance sign-offs, ticket exports and handover notes to the overdue invoice in the Evidence Vault. From that organised record, WolfX helps you prepare a Letter Before Action — the formal written demand a business sends before considering court — and a Court Readiness Pack that pulls the invoice, the debt calculation and the supporting evidence into one structured set for internal, solicitor, compliance or pre-action review.

WolfX is software, not a law firm. It does not give legal advice, does not file court claims for you, does not collect payments directly, and does not guarantee that an invoice will be recovered. What it does is reduce the time and uncertainty of getting from "the client has not paid" to "we have an organised, evidence-backed case ready to escalate".

A Letter Before Action (LBA) is a formal letter setting out the debt, what it relates to and what you expect the debtor to do, sent before court proceedings are considered. For a company debtor, the Practice Direction on Pre-Action Conduct applies, and at least 14 days' notice before issuing a claim is typical. The separate Pre-Action Protocol for Debt Claims — with its 30-day reply window and information sheet — applies only where the debtor is an individual or a sole trader, which can include some small IT contractors and freelancers.

A clear LBA for an IT invoice references the SOW or order, the deliverables, the acceptance position and any statutory interest and compensation you are claiming. WolfX helps you generate that letter from the evidence you have organised, so the demand reflects the actual delivery record.

A Court Readiness Pack is an organised bundle that brings together the invoice, the debt and interest calculation, the contract or SOW and the supporting evidence — acceptance records, tickets, handover notes — in one structured set. It is designed to make internal, solicitor, compliance or pre-action review faster.

A Court Readiness Pack is not a court filing and is not an official or certified court document. It does not start proceedings. WolfX does not currently file claims, issue County Court Judgments, or act as a court. The pack is preparation: it organises what you would otherwise have to assemble by hand before anyone decides whether to take a matter further.
