🌐 URL Routes & Actions

Expected routes following ERP patterns:

🧮 Calculation Methods

Partner Balance Updates

// Withdrawal processing
function processWithdrawal($partnerId, $amount, $sourceType, $sourceId) {
    // Update partner balance
    $partner = $partnerDAO->load($partnerId);
    $partner->partnerbalance -= $amount;
    $partnerDAO->update($partner);
    
    // Update business account
    if ($sourceType == 'save') {
        $save = $saveDAO->load($sourceId);
        $save->savevalue -= $amount;
        $saveDAO->update($save);
    } else if ($sourceType == 'bank') {
        $bank = $bankDAO->load($sourceId);
        $bank->balance -= $amount;
        $bankDAO->update($bank);
    }
}

Inter-Partner Transfer

// Transfer between partners
function transferBetweenPartners($fromPartnerId, $toPartnerId, $amount) {
    // Validate source balance
    $fromPartner = $partnerDAO->load($fromPartnerId);
    if ($fromPartner->partnerbalance < $amount) {
        throw new Exception("Insufficient balance");
    }
    
    // Update balances
    $fromPartner->partnerbalance -= $amount;
    $toPartner = $partnerDAO->load($toPartnerId);
    $toPartner->partnerbalance += $amount;
    
    // Save updates
    $partnerDAO->update($fromPartner);
    $partnerDAO->update($toPartner);
}

Daily Entry Generation

// Generate accounting entry for withdrawal
function createWithdrawalEntry($partnerId, $amount, $date) {
