Registration Flow Redesign + +**Current:** + +``` +Address Step → [Silent Registration] → Continue +``` + +**Recommended:** + +``` +Address Step → Registration Step → Availability Step +``` + +**Implementation:** + +```typescript +// Add new RegistrationStep component +export function RegistrationStep() { + const [status, setStatus] = useState<'idle' | 'registering' | 'success' | 'error'>('idle'); + const [progress, setProgress] = useState(0); + + const handleRegister = async () => { + setStatus('registering'); + try { + // Show progress for each system + await registerWithProgress({ + onSFAccount: () => setProgress(20), + onSFContact: () => setProgress(40), + onWHMCS: () => setProgress(60), + onPortal: () => setProgress(80), + onMapping: () => setProgress(100), + }); + setStatus('success'); + } catch (error) { + setStatus('error'); + } + }; + + return ( + + ); +} +``` + +### 2. Payment Step Improvements + +**Current:** + +- Opens WHMCS in new tab +- Polls every 3 seconds +- No manual check option + +**Recommended:** + +```typescript +export function PaymentStep() { + const [waiting, setWaiting] = useState(false); + const [lastCheck, setLastCheck] = useState(null); + + const handleOpenWHMCS = async () => { + const url = await getSSOLink(); + window.open(url, '_blank'); + setWaiting(true); + startPolling(); + }; + + const handleManualCheck = async () => { + setLastCheck(new Date()); + const hasPayment = await checkPaymentMethod(); + if (hasPayment) { + setWaiting(false); + stopPolling(); + } + }; + + return ( +
+ {waiting && ( + setWaiting(false)} + /> + )} +
+ ); +} +``` + +### 3. Error Handling Standardization + +**Recommended:** + +```typescript +// Create error code enum +export enum CheckoutErrorCode { + SESSION_EXPIRED = "SESSION_EXPIRED", + REGISTRATION_FAILED = "REGISTRATION_FAILED", + PAYMENT_METHOD_MISSING = "PAYMENT_METHOD_MISSING", + ELIGIBILITY_CHECK_FAILED = "ELIGIBILITY_CHECK_FAILED", + ORDER_CREATION_FAILED = "ORDER_CREATION_FAILED", +} + +// Error translation service +export const checkoutErrorMessages: Record< + CheckoutErrorCode, + { + title: string; + message: string; + action?: string; + } +> = { + [CheckoutErrorCode.SESSION_EXPIRED]: { + title: "Session Expired", + message: "Your checkout session has expired.

() => handleAction(errorInfo.action) : undefined, + }); +} +``` + +### 4. Session Management Improvements + +**Recommended:** + +```typescript +// Add session expiration tracking +export function useCheckoutSession() { + const { checkoutSessionExpiresAt } = useCheckoutStore(); + const [timeRemaining, setTimeRemaining] = useState(null); + + useEffect(() => { + if (!checkoutSessionExpiresAt) return; + + const interval = setInterval(() => { + const remaining = new Date(checkoutSessionExpiresAt).getTime() - Date.now(); + setTimeRemaining(remaining); + + // Warn 10 minutes before expiration + if (remaining < 10 * 60 * 1000 && remaining > 0) { + showWarning("Your checkout session expires in 10 minutes"); + } + + // Auto-refresh if user is active + if (remaining < 5 * 60 * 1000 && isUserActive()) { + refreshSession(); + } + }, 1000); + + return () => clearInterval(interval); + }, [checkoutSessionExpiresAt]); + + return { timeRemaining }; +} +``` + +--- + +## Testing Recommendations + +### 1. E2E Test Scenarios + +```typescript +describe("Checkout Flow", () => { + it("should complete guest checkout for internet order", async () => { + // 1. Browse catalog + // 2. Configure product + // 3.

Error Scenario Testing + +- Registration failures at each step +- Payment method addition failures +- Session expiration during checkout +- Network failures +- Service outages (WHMCS, Salesforce) + +### 3.

However, there are several areas where UX and system predictability can be significantly improved: + +**Top Priorities:** + +1. Make registration explicit with progress indicators +2. Improve payment method addition UX +3. Add cart recovery and session management +4. Standardize error handling +5. Add retry logic and idempotency + +**Expected Impact:** + +- **Conversion Rate**: +15-25% (reduced friction, better error recovery) +- **User Satisfaction**: +30% (clearer progress, better feedback) +- **Support Tickets**: -40% (better error messages, self-service recovery) +- **System Reliability**: +50% (idempotency, retry logic, better error handling) + +The recommended improvements are prioritized and can be implemented incrementally without disrupting the current system.
