Field Sales Rep Mobile App Development

Why field reps stop using the CRM mobile app

Most CRMs were designed for someone at a desk. The mobile versions shrink the desktop view onto a phone, which works for checking a phone number and fails for everything else a rep does in the field. Ask an outside rep at a building products distributor or a medical device company how they really work and you hear the same story: notes go into the phone’s notes app, orders go by text to inside sales, and the CRM gets updated on Friday afternoon, if at all.

The damage shows up in management, not just in the rep’s day. Visit history is incomplete, so a new rep inherits a territory blind. Forecasts rely on memory. Samples go out without a record of who received them. Tepia hears these complaints in nearly every sales operations discovery session.

A purpose built field sales app fixes this by matching the rep’s actual day: plan, drive, visit, order, record, repeat. It writes to the CRM in the background so the system of record stays complete without asking reps to become data entry clerks.

A field sales day, screen by screen

Tepia designs around the sequence a rep actually follows. Here is how a typical day maps to the app for a distributor’s outside sales team.

1. Morning plan: the app proposes a route from accounts due for a visit, open opportunities and appointments, and the rep drags stops into order.
2. Before the visit: a briefing card shows what the account bought last quarter, open orders, recent returns or complaints, and promises made last time.
3. On site: the rep checks in with GPS, captures shelf or display photos, notes competitor products, and records samples left behind.
4. Order entry: the rep searches the catalog by name, SKU or barcode scan, sees branch availability and the account’s terms, and submits the order for approval or straight to the ERP.
5. After the visit: the rep records a voice note in the truck, and the app turns it into a summary, next steps and dated follow up tasks.
6. End of day: mileage is logged from the route, and the manager sees completed calls without asking for a report.

Tepia validates this flow with ride alongs before any screen is final, because the details of a real day, such as receiving docks with no signal, change the design.

Features and who benefits

Each feature has to save the rep time and give managers better information at the same moment. Tepia uses a table like this to agree on scope:

The voice note feature uses OpenAI or Anthropic model APIs with your CRM fields as the target structure. See our AI call notes and summaries page for how Tepia keeps that accurate.

Syncing with your CRM and ERP without losing data

A field sales app is only as good as its sync. Reps work offline for hours, edit the same account as inside sales, and expect orders to go through even when submitted from a dead zone. Tepia designs the sync rules explicitly:

• Offline first storage on the device, with the day’s accounts, catalog and availability cached before the rep leaves home.
• Field level merge so a rep’s visit note and an inside sales update to the same account do not overwrite each other.
• Queued orders that submit in sequence when signal returns, with a clear status so the rep knows the order landed.
• CRM mapping to Salesforce, HubSpot or Dynamics 365 activities, contacts and opportunities, so reporting stays in the tools leadership already reads.
• ERP connection for orders, availability and account terms through NetSuite, Business Central or your existing system.

Phones get left in rental cars and coffee shops, so Tepia also plans for lost devices. Customer data on the phone is encrypted, sign in uses your company identity provider, and the app works with mobile device management tools such as Microsoft Intune so IT can wipe company data remotely without touching a rep’s personal photos. When a rep leaves, access ends the moment their account is disabled.

How Tepia approaches field sales app development

Tepia uses its six phase process with a US based project manager who works alongside your sales operations lead.

1. Discovery: ride alongs with two or three reps in different territories, interviews with managers and inside sales, and a review of CRM and ERP data. Deliverables are an Investigation Summary, an Interview Summary and User Stories such as a rep taking a reorder in a store with no signal.
2. Design: moodboards, a style guide and wireframes for the briefing card, order screen and voice note flow, tested one handed in daylight.
3. Development and Testing: an Alpha with a single team and a Beta across regions, with test plans for offline sync, order accuracy and battery use over a full day.
4. Training: short hands on sessions at a sales meeting, built around user story scenarios.
5. Launch: App Store and Google Play or managed device distribution, account data loads and support reps for the first weeks.
6. Support: bug fixes and feature requests from the field.

Most programs follow the usual Tepia rhythm: 1 to 3 months of Discovery, 2 to 6 months of development and QA, then about a month for launch. If your current CRM app has become shelfware, talk to Tepia.
