Sales reps aren’t behind desks - they’re in fields, in motion, and often offline. When we build OrderIT, a B2B sales order booking app, we knew a mobile first approach wasn’t optional, it was the only way. Here’s what we learned : 

1. Design for Context, Not Screens - Sale reps used the app in noisy markets, while travelling, or in low-connectivity zones. So we prioritise speed, offline access and quick inputs over fancy features. Takeaways : Mobile First = Context First.

2. Simplify Everything - We stripped every flow down to essentials- one tap reorder, auto fill forms, smart fillers. The goal? Got in, get the order, move on. Takeaways : Mobile UX demands Clarity and Speed.

3. Give instant feedback : Order confirmations, sync statuses and subtle animations helped users feel in control - no second - guessing. Takeaway : Good micro interactions build trust.

   Expect Interruptions : Calls, weak networks and multitasking are the norm. OrderIT saved in progress orders, worked offline and picked up right where reps left off. Takeaways : Design for Real World Friction.

4. Show Only What Matters : We highlighted stock, past orders, and payment status — no overwhelming dashboards. Takeaway: Prioritize what helps users act faster.

Final Thought - A mobile-first mindset isn’t about shrinking screens. It’s about respecting your users’ reality. For sales teams, great design leads to faster orders — and that means better business.
