var mongoose = require('mongoose')

This code seems to be duplicated in your project.

var expenseItem = require('./common/line-item')

var expenseSchema = new mongoose.Schema({
  date: { type: Date, default: Date.now },
  company: { type: mongoose.Schema.Types.ObjectId, ref: 'Company', required: true },
  category: ['Purchases', 'Motor Fuel', 'Motor Serv/Repair',
    'Motor Tax/Ins', 'Van DOE', 'Public Laibility Insurance',
    'Advertising', 'Tele/bband', 'Training', 'Office Expenses',
    'Sub Contractor', 'Landfill', 'Ber Cert Fees', 'Bank Fees',
    'Sundry', 'Heating', 'Sponsorship', 'Equipment Hire', 'Electricity'],
  items: [expenseItem],
  totalVat: { type: Number, default: 0.00 },
  totalExVat: { type: Number, default: 0.00 },
  total: { type: Number, default: 0.00 }
})

expenseSchema.pre('save', function (next) {
  let overallTotal = 0.00
    // All the items should give the total
  this.items.forEach(function (item) {
    overallTotal = overallTotal + item.total
  })

  this.total = overallTotal
  next()
})

module.exports = mongoose.model('Expense', expenseSchema)
