Mobile App for UK Tradespeople: Quoting and Invoicing on the Go

For most UK tradespeople, the working day is spent on site, not at a desk. Quoting, invoicing, and job documentation that requires a laptop has historically meant that those tasks pile up in the evenings — if they get done at all. The shift to mobile-first trade management software means that the administrative tasks of running a trade business can now be completed in the natural gaps of the working day: between jobs in the van, at the end of a site visit while the client is still present, or during a tea break on a large commercial project.

Why Mobile Matters for UK Tradespeople

The UK trade industry has one of the highest proportions of self-employed workers of any sector, and the vast majority of those workers are primarily field-based. A plumber who spends seven hours on site and one hour commuting does not have a natural opportunity to sit at a desk, open a laptop, and process the day's administrative work — particularly if they also have a family or other commitments outside work hours. Mobile quoting and invoicing changes this dynamic by making the tools available at the moment they are most useful: the quote is created on site immediately after a site visit, while the scope of work is fresh; the invoice is raised the moment a job is completed, while the client is present and ready to acknowledge the work; the site photograph is taken and uploaded before the contractor leaves the property. Each of these actions, taken at the right moment, improves both the quality of the output and the speed of the business process it supports.

Quoting on Site with QuotCraft Mobile

QuotCraft's mobile app for iOS and Android provides the full quotation workflow in a mobile-optimised interface. After a site visit, the contractor opens the app, creates a new quote linked to the client's record, adds line items by searching the product catalogue or entering them manually, applies margin rules, sets the validity period and payment terms, and sends the quote to the client — all without leaving the app. For contractors who use wholesaler integrations, material prices can be pulled from Rexel, Sonepar, or Würth UK directly within the mobile app, reflecting the same trade pricing as the desktop version. Voice-to-quote, available on paid plans, allows the contractor to dictate the job description on the drive back from site and have a draft quote ready for review and sending within minutes of arriving home.

Invoicing and Getting Paid Faster

Raising an invoice immediately on completion is one of the most effective ways to accelerate payment. Invoices that are sent the same day the work is done arrive when the job is fresh in the client's mind, when the client has had the opportunity to inspect the completed work, and before the client's accounts payable process for the week has already run. Clients who receive an invoice days or weeks after the work was done are less receptive, more likely to raise queries about what was included, and sometimes less financially prepared to pay. QuotCraft's mobile app allows the contractor to raise the invoice directly from the accepted quote — converting line items automatically and avoiding the need to re-enter any information — and send it to the client with one tap. Payment links for card payment or GoCardless direct debit are included in the invoice notification automatically.

Photo Upload with Timestamps

Site photography has become an increasingly important part of trade contractor administration, both for demonstrating the quality of completed work to clients and for providing evidence in disputes about the scope of work, the condition of an installation at the time of handover, or the state of a building before work began. QuotCraft's mobile app allows photographs to be taken directly within the app or uploaded from the device's camera roll and attached to a specific project record with a timestamp drawn from the device's clock. For contractors working on properties where pre-existing damage is common — roof replacements on older properties, bathroom refurbishments in Victorian houses — photographing the site before work begins provides important protection against claims that the contractor caused damage that was pre-existing. For work subject to building regulations sign-off, photographs of concealed work — buried pipework, in-wall wiring, concealed structural repairs — taken before boarding or plastering provides the evidence that a building control inspector would otherwise need to inspect in person.

Field Documentation and CDM Records

For contractors subject to CDM Regulations 2015 obligations, the mobile app provides a convenient means of uploading and accessing construction phase plan documents, risk assessments, and method statements from site. A site manager who needs to share a method statement with a visiting HSE inspector can access it from their phone rather than having to call the office or search through paper files in the van. Site-specific documentation — scaffold inspection records, asbestos survey references, permit to work certificates — can be uploaded to the project record from site as soon as they are issued, ensuring that the documentary record is maintained contemporaneously rather than relying on manual filing when the contractor returns to the office. This is particularly important for notifiable projects where CDM documentation must be readily available on site under Regulation 13 of the CDM Regulations.

Managing Multiple Jobs and Teams from Mobile

For contractors running more than one operative, the mobile app provides visibility of all active projects, outstanding invoices, and team schedules in a single interface. A sole director of a small electrical company can see which engineer is on which site, which invoices are overdue, which quotes are awaiting client approval, and whether any payment has been received since the morning, all from the van between site visits. Push notifications alert the contractor to significant events — a quote has been approved by a client, a payment has been received, an invoice is approaching its due date — without requiring them to log in and check the dashboard manually. For apprentices and employed operatives, the mobile app's time tracking feature allows them to log their start time, end time, and the project they worked on each day, providing the records needed for NMW compliance and for understanding actual labour cost at the job level.

How to Get Started with QuotCraft Mobile

QuotCraft's mobile app is available as a free download on the Apple App Store and Google Play Store, and is included with all QuotCraft plans including the free tier. Existing QuotCraft users can log in immediately with their existing credentials and access all their clients, projects, quotes, and invoices from their phone or tablet. New users can sign up directly in the app and begin quoting within minutes. The mobile app synchronises in real-time with the web platform, so information entered on mobile is immediately visible on desktop and vice versa. For contractors who work primarily from their phone and rarely use a desktop browser, the mobile app provides complete access to all core QuotCraft features including client management, quotations, invoices, payments, time tracking, and document storage — making it possible to run a professional trade business entirely from a smartphone.
