B2B Mobile App Development for Field Operations
Apps that replace phone calls and WhatsApp chains with a single, role-based workflow — for teams that work from job sites, not desks.
The Phone-and-WhatsApp Problem
Quotes sent over WhatsApp. Orders confirmed by phone call. Approvals that live in someone's inbox. It works, until it doesn't — a missed message costs a contract, and there's no record of what was agreed.
I build role-based B2B apps that replace that workflow: one system where quotations, orders, approvals, and bookings happen in one place, with a clear record of who did what.
Who This Is For
- Construction, equipment rental, and supply businesses still coordinating over phone and WhatsApp
- Marketplaces connecting buyers and suppliers who need real-time visibility on both sides
- Operations teams that need role-based access — different views for admins, field staff, and customers
What You Get
- Quotation & ordering flows with real-time pricing and status updates
- Approval workflows with role-based permissions for different user types
- Equipment or inventory booking with live availability, not static listings
- Payment processing integrated into the confirmation flow
- Delivery or fulfillment tracking so both sides know status without a phone call
- Push notifications at every step: request sent, accepted, paid, dispatched
How We'll Work Together
Document exactly how orders, approvals, or bookings currently happen — and where they break.
Define what each user type — buyer, supplier, admin, field worker — actually needs to see and do.
Flutter app plus backend, covering the full request-to-confirmation flow.
Ship to real users, then refine based on what actually gets used.

Frequently Asked Questions
What kind of businesses does this fit?
Construction, equipment rental, and B2B supply businesses that run on phone calls and WhatsApp today — see the readymix concrete-ordering and equipment rental marketplace case studies.
Can the app handle different user roles?
Yes — buyer, supplier, admin, and field-worker roles with different permissions and views are a standard part of this kind of build.
Do you handle payments too?
Yes, payment gateway integration is part of the flow when the workflow includes a transaction, as in both of the marketplace apps referenced above.
