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.

The platform

Joblogy is job management software for trades and field service businesses: electricians, plumbers, builders, HVAC, cleaning and maintenance teams. It is a Backendz product, designed and built in-house, and it is currently in development.

It takes a job from the first enquiry through quote, schedule, the work on site, invoice and payment. The office runs it from a web app, and engineers carry it in a mobile app on iOS and Android.

The challenge

Most small trade businesses run on a phone, a diary, a spreadsheet and a pile of paper job sheets. Quotes go out late, engineers get double-booked, materials never make it onto the invoice, and payment chasing takes up evenings.

Existing tools either cover one piece of that, or are built for large field service companies and priced to match. We wanted one product that a five-van electrical firm could run its whole business on from day one.

The solution

Joblogy puts every job on a single board, from enquiry to paid, with quotes, costs, photos and invoices on the job card. The schedule shows each engineer's day, unscheduled jobs ready to drag in, booked hours and travel time.

In the field app, engineers see today's jobs, navigate and call the customer, track time, work through a checklist, add photos, materials and voice notes, capture a signature and take payment on site. Paid invoices sync to the accounting system so the office does not key anything twice.

How we built it

Research: Mapped how trade businesses run a job today, from the first call to getting paid.
Product design: Designed the office web app and the engineer app as one system, around the job card.
Build: Building the web app and the iOS and Android apps in-house, one workflow at a time.
Pilot: Next: pilot with trade businesses, then open it up more widely.
