What does Backendz do?

Backendz is a custom software development and AI engineering company. We build bespoke business applications, artificial intelligence systems, integrations and data platforms, and we support them in production after launch.

How much does bespoke software development cost?

Most focused operational systems fall between £15,000 and £50,000. Larger multi-module platforms with integrations start around £50,000. A two-week discovery sprint, which produces a costed build plan, is a fixed fee in the low thousands. We publish this because vague pricing wastes everybody's time.

How long does it take?

A focused system typically takes six to twelve weeks from kick-off to production. Larger platforms run three to six months. We deliver in stages so working software is in your hands well before final delivery.

Who owns the code and the intellectual property?

You do. Source code, data and intellectual property transfer to you, and this is stated in the contract from the outset.

Do you build AI agents, or is it a wrapper?

We build agent and multi-agent systems with tool use, defined human approval checkpoints and full audit logging, designed so that an incorrect action is detected and recoverable rather than silent. Most of our AI work is integration with existing ERP, CRM and document systems, not replacement.

Are you a UK company?

Backendz is UK-registered and contracts under English law. Our engineering team is based in Pakistan, which is how we deliver enterprise-standard work at a competitive rate. We state this openly because it is relevant to procurement.

Can you take over software built by someone else?

Yes. We carry out code audits and architecture reviews before agreeing to inherit a system, so that both sides understand its condition before any commitment is made.

Policy & Contract Assistant

Answers from contracts, policies and procedures, with the exact clause beside each response

The project

We built a document assistant that helps operations, HR and finance teams find answers in their contracts, policies and procedures. People ask a question in plain English, receive a concise response and can open the supporting clause alongside it.

The application combines a searchable document library, source-linked answers, document access rules and a route for unanswered questions. It also shows policy owners which questions come up repeatedly and where their documents leave gaps.

The challenge

The information teams need is often already written down, but spread across contracts, handbooks and procedure documents. Answering a routine question means searching several files, checking which version applies or asking a colleague who knows where to look.

A useful assistant needed to do more than produce a plausible reply. Staff had to be able to check the wording behind an answer, while restricted documents stayed restricted and missing information remained visible.

The solution

We built a retrieval-based assistant around the document library. Documents are split into clauses and indexed so that each question can be matched to relevant passages. The assistant uses those passages to compose a short answer, with numbered references that open the source beside it and highlight the clause.

Document permissions are applied during retrieval, so answers draw only on material the person asking is allowed to access. Uploading a new document version triggers re-indexing, keeping the searchable material aligned with the library.

When the available documents do not answer a question, the assistant explains the gap, shows the closest relevant material and offers a handover to the right team. An insights view brings together common questions, helpfulness feedback and unanswered topics, giving document owners a practical list of material to clarify or add.

What it does

Plain-English questions across contracts, policies and procedures
Answers cite the exact clause, with the source opened beside it
Says when the documents don’t answer the question
Send unanswered questions to the right team
Access rules: answers only from documents the person can see
Document library with re-indexing when a new version is uploaded
Insights: most asked questions and gaps in your documents

How we built it

Map documents and access: Organised contracts, policies and procedures and defined which users could access each document.
Build clause retrieval: Split and indexed the documents so relevant passages could be retrieved with a traceable source.
Create the answer workspace: Built plain-English questions, cited responses and a side-by-side source view with highlighted clauses.
Handle gaps and review: Added unanswered-question handover and insights, and checked restricted documents, conflicting versions and questions without supporting text.
