Custom & quick tasks

Custom Business App

One connected system built around how your business runs: several modules, such as quotes, orders, stock, invoices and a customer portal, sharing one database.

For businesses that run on a patchwork of spreadsheets, WhatsApp groups and apps that do not talk to each other. We build one connected system around how you work, with modules that share the same data and link to the tools you keep, such as your accounting software, Shopify or Stripe. Tell us what you need and we reply with a written scope and a fixed quote.

  • 10+ years experience
  • Fixed prices
  • You own everything
  • Secure Stripe payments
  • Written scope & tracking
  • Fix-or-refund promise

What's included

  • Free written scope and fixed quote: we map how you work today and what the app must do
  • Several modules in one app, sharing one database (e.g. quotes, orders, stock, invoices, approvals)
  • Logins and roles for staff, managers and, if needed, your customers
  • Connections to the tools you keep: Xero, QuickBooks or Zoho Books, Shopify, Stripe / HitPay, WhatsApp, Google or Microsoft 365
  • Works in the browser on phone, tablet and desktop
  • Built and delivered in stages, so you test each module before the next
  • Hosted in your own account; the source code and data are yours
  • Admin guide, handover and 30 days of bug fixes after launch

Examples of what we can build

Ideas, not client projects

Almost anything your business needs can be built. A few examples:

  • Quote → order → invoice

    Quotes become orders and then invoices in one click, and invoices and payments go straight to Xero, QuickBooks or Zoho Books.

  • Stock, sales and accounting in one

    Stock levels, sales orders and purchase orders in one place, with sales and costs flowing into your accounting software.

  • Customer portal

    Customers log in to see their orders, invoices and statements, and pay by PayNow or card.

  • Staff expense and leave approvals

    Staff submit a claim with a receipt photo or apply for leave; managers approve on their phone; approved claims go to accounting.

  • Service and technician job orders

    Jobs assigned to technicians, checklists and photos on site, the customer signs, and the invoice is raised automatically.

  • Membership and subscriptions

    Members, plans, renewals and attendance in one place, with automatic billing and a member self-service page.

  • Shopify + warehouse + accounting panel

    Shopify orders, picking and packing, stock across locations and payouts reconciled, on one screen.

  • Reporting dashboard

    Sales, margins, cash and team numbers from all your systems, updated automatically.

Custom Business App — questions

Custom Tool or Dashboard is one tool for one job. Custom Business App is a larger, connected system with several modules sharing one database, for example quotes, orders, stock, invoices and a customer portal working together.

Yes. Xero, QuickBooks Online and Zoho Books all have APIs, so invoices, payments and contacts can flow between them and your app. Your accountant still keeps the books; the app saves the retyping.

From the brief, we write a scope listing every module and screen, with a fixed price and timeline. You pay only if you accept it, and larger builds are split into stages you approve one by one.
