Bespoke software development

Bespoke software development for UK contractors and field-service businesses

SENRAB builds bespoke software that takes paper forms, spreadsheets and re-keyed admin out of contractor businesses. The work done on site reaches the office as a digital record, so jobs, evidence and invoices can be seen in one place.

Who it is for. Owners and directors of UK construction contractors, telecoms contractors and field-service businesses whose jobs still run on paper job sheets, spreadsheets and message threads.

Where paper and spreadsheets slow the work down

  • Paper job sheets are filled in on site and typed into a spreadsheet or system at the office, so the same data is entered twice.
  • Completion evidence, photos and signatures are chased between the site and the office.
  • Handovers from the field team to the office are slow, so approvals and invoices wait.
  • Spreadsheets and disconnected systems leave nobody with one reliable view of where each job stands.

What we typically build, scoped to your process

What we would typically build

Each is scoped per project.

  • Digital job sheets and site forms that replace paper
  • One job record with status, costs and notes
  • Photos and documents attached to the job
  • Approvals recorded against the job, with who agreed and when
  • A handover from completed work to invoice
  • Reminders and reports for managers and the office

What it looks like in use

Made-up data in a job board: the kind of record a paper job sheet becomes once it is captured digitally. What we build depends on your process.

What you should see in the business

  • Less repeated data entry between the site and the office
  • Completion evidence kept with the job it belongs to
  • A record the office can see as the job progresses
  • One view of job status for owners and directors
  • A clearer route from completed work to invoice

How it could work in a real business

Illustrative scenario

A contractor moving off paper job sheets

Paper at the start of the job and re-typing at the end. Not a customer project.

  • TodayJob sheets are filled in on paper on site.

    With one connected systemThe job sheet is completed digitally on site and the office can see it.Built to your requirements.

  • TodaySomeone types each sheet into a spreadsheet at the office.

    With one connected systemThe details are entered once and carried through the job record.

  • TodayPhotos and signatures are chased from engineers.

    With one connected systemPhotos and sign-offs are attached to the job when the work is done.Built to your requirements.

  • TodayThe office rings round to find out what is finished.

    With one connected systemJob status is visible without a phone call.

  • TodayInvoices wait for the paperwork to arrive.

    With one connected systemThe completed record carries through to the invoice.

Sectors this can be configured for: Construction, Telecoms, Facilities management, Commercial cleaning.

What shapes the cost of this system

Replacing one paper process can fit a Starter System. Several connected workflows, such as job sheets, evidence, approvals and invoicing together, may fit a Business System. Work that spans teams, systems or departments may fit Advanced / Enterprise.

  • Starter System Digitising one focused process.
  • Business System Several connected workflows working together.
  • Advanced / Enterprise Complex requirements that span teams, systems or departments.

Hosting and support are agreed with you up front. We don't publish figures for them because they depend on what is built.

Tell us about your process in the form. We reply to set up a short conversation to talk through the scope level that fits and what it is likely to cost.

What moves the cost

  • How many forms and processes are replaced, starting with one
  • Which other systems, such as accounts software, the records must connect to
  • How many people use it, and what each of them needs to see
  • How much existing spreadsheet data needs bringing across

From first conversation to day-to-day use

01

Understand the process

We follow a real job from enquiry to invoice, including the paper, spreadsheets and messages it passes through, and note where data is re-keyed or waits.

02

Design around you

We agree which paper forms and spreadsheets are replaced first, what the system must record, and which parts come from our configurable foundation and which are built to your requirements.

03

Show the proposed solution

You see the proposed screens and flow on example screens built around your own scenario before anything is built.

04

Build and test in stages

We replace one process at a time, starting with the one that costs you most, and test each stage with the people who will use it. Delivery is one week from a completed specification, for the scope it describes.

05

Support rollout and adoption

People move over in an order that suits the business. We host and support the system, and extend it one process at a time as the way you work changes.

Not sure where to start? That is what the review is for.

Questions people ask

What does bespoke software development mean in practice?

It means software designed around how your business already runs, not a product you bend your work to fit. For a job-based business it starts with the paper forms and spreadsheets that slow a job down, and replaces them with one digital record per job.

Do you build everything from scratch?

Not always. For job management we can start from a configurable foundation and build the pieces your process needs on top of it. What comes from the foundation and what is built to your requirements is agreed when the specification is agreed.

When would off-the-shelf software suit us better?

When a standard product already covers how you work and you are content to follow its way of doing things. We will tell you if that is the case. Bespoke work earns its place where your forms, process or reporting do not fit a standard product.

Can it connect to our accounts software or other systems?

Connections with other systems are scoped per project. We have delivered an integration for a client, and we say plainly during scoping whether a link is practical rather than assume it.

Who owns the software and our data?

SENRAB owns the code. Your business data stays yours, along with the right to use your configured system.

How long does a build take?

Delivery is one week from the specification being completed, for the scope that specification describes. Anything outside it is scoped and agreed separately.

Is there a fixed price?

We scope the work first, then talk through the likely cost with you. How pricing works, and what is agreed up front for hosting and support, is explained on the pricing page.

What should we replace first?

Pick the paper form or spreadsheet that costs you the most time or causes the most chasing, and scope that first. The free operational review is a good place to choose it.
