Acumatica Mobile App Development

Introduction

Mobile access to Acumatica ERP is essential for modern businesses. Whether you need field service applications, sales automation, or inventory management on the go, Acumatica provides APIs and tools to build powerful mobile applications.

In this guide, we'll explore mobile app development with Acumatica, covering API integration, framework options, and best practices for building effective mobile solutions.

Mobile Development Options

Several options exist for building mobile apps with Acumatica:

• Acumatica Mobile Framework - Built-in responsive design
• Custom Native Apps - Swift/Kotlin with REST API
• Cross-Platform Apps - React Native, Flutter, Xamarin
• Progressive Web Apps - Web-based mobile experience
• Acumatica Field Service - Pre-built mobile solution

API Integration

Connect your mobile app to Acumatica using the REST API:

// JavaScript/TypeScript API Client
class AcumaticaMobileAPI {
    constructor(baseUrl, companyId) {
        this.baseUrl = baseUrl;
        this.companyId = companyId;
        this.token = null;
    }
    
    async authenticate(username, password) {
        const response = await fetch(`${this.baseUrl}/oauth/token`, {
            method: 'POST',
            headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
            body: new URLSearchParams({
                grant_type: 'password',
                client_id: 'mobile-app',
                username: `${this.companyId}\\${username}`,
                password: password
            })
        });
        
        const data = await response.json();
        this.token = data.access_token;
    }
    
    async getCustomers() {
        const response = await fetch(`${this.baseUrl}/api/data/AR303000`, {
            headers: { 
                'Authorization': `Bearer ${this.token}`,
                'Accept': 'application/json'
            }
        });
        return response.json();
    }
}

Mobile Framework Setup

Set up a React Native app to integrate with Acumatica:

// React Native API Service
import axios from 'axios';

const api = axios.create({
    baseURL: 'https://your-acumatica-instance.com',
    timeout: 10000,
});

api.interceptors.request.use(config => {
    const token = await AsyncStorage.getItem('acumatica_token');
    if (token) {
        config.headers.Authorization = `Bearer ${token}`;
    }
    return config;
});

export const CustomerService = {
    getCustomers: async () => {
        const response = await api.get('/api/data/AR303000');
        return response.data;
    },
    
    createCustomer: async (customerData) => {
        const response = await api.post('/api/data/AR303000', customerData);
        return response.data;
    },
    
    updateCustomer: async (customerId, customerData) => {
        const response = await api.put(`/api/data/AR303000/${customerId}`, customerData);
        return response.data;
    },
};

Offline Capabilities

Implement offline functionality for field work:

// Offline Data Storage
import AsyncStorage from '@react-native-async-storage/async-storage';

class OfflineDataService {
    async saveForOffline(key, data) {
        const timestamp = new Date().toISOString();
        await AsyncStorage.setItem(key, JSON.stringify({
            data,
            timestamp,
            synced: false
        }));
    }
    
    async getOfflineData(key) {
        const stored = await AsyncStorage.getItem(key);
        if (stored) {
            return JSON.parse(stored);
        }
        return null;
    }
    
    async syncOfflineData() {
        const keys = await AsyncStorage.getAllKeys();
        const offlineItems = await AsyncStorage.multiGet(
            keys.filter(k => k.startsWith('offline_'))
        );
        
        for (const [key, value] of offlineItems) {
            const item = JSON.parse(value);
            if (!item.synced) {
                await this.syncToServer(item.data);
                await AsyncStorage.setItem(key, JSON.stringify({
                    ...item,
                    synced: true
                }));
            }
        }
    }
}

Offline features to consider:

• Local data caching
• Queue offline changes
• Automatic sync when online
• Conflict resolution

Best Practices

• Optimize API calls - Minimize network requests
• Implement caching - Reduce server load
• Handle offline - Work without connectivity
• Secure data - Encrypt sensitive information
• Test on devices - Real device testing
• Monitor performance - Track app metrics
• Provide feedback - User loading indicators
