销售额是指纳税人销售货物、提供应税劳务或服务，从购买或接受应税劳务方或服务方收取的全部价款和价外费用，但是不包括向购买方收取的销项税额以及代为收取的政府性基金或者行政事业性收费。
Sales volume refers to the total price and additional fees collected by taxpayers from the purchaser or recipient of taxable services or labor services when the taxpayer sells goods or provides taxable labor or services, but does not include the output tax collected from the purchaser and the government funds or administrative fees collected on behalf of the purchaser.
如何提高销售额：
1.努力提升产品质量
企业的产品，要有好的销售额，首先一定要做好产品自身，产品的质量是最关键的一点，一款连质量都无法保证的产品是不会获得用户青睐的，即便是一时风靡，但是却断了所有退路，如曾经风光一时的三鹿。所以说，要想提升销售额，一定要严把质量关。
2.努力做好售后服务
卖出去产品，并不是企业销售的结束，或者说，仅仅只是销售的开始。一款好的产品，不仅体现在过硬的品质上，更体现在高质量的售后服务上。售后服务做到位，用户的口碑好了，就会为你带来更多的用户，这也算是一种小范围的口碑营销。
3.大面积的媒体广告
广告的效应是毋庸置疑的，最显著的当属电视广告，黄金时段的天价广告费用足以证明他的价值；其次是平面广告、纸质媒体的广告和公车广告等。此类广告对提升销售额的作用比较显著，但是巨额的广告费用也是一些企业所无法承担的，特别是对于资金相对短缺的中小企业来说，大力铺设显然不现实。故此类广告不是越多越好，要量力而行。
4.网络广告
网络广告相对于上述所说的媒体广告，花费相对少一些，效果也很显著。所以越来越多的企业开始利用网络广告来销售自己的产品。网络广告有在网站平台上的付费广告，还有的做竞价排名。网络广告的费用相对媒体广告来说，会少一些，但是对于中小企业来说，费用依然高昂，而且网络广告有个弊端，越到后期花费越多，效果反而更不显著。
5.免费的网络营销推广
免费的网络营销推广指的是普遍在用的一种方式。具体做法为在各大商贸平台、大型论坛、博客平台、用户邮箱免费发布广告信息。这种方式由于费用少，只需耗费一定的时间和人力，所以特别受中小企业的青睐。但是在具体实施过程中还是会出现这样那样的问题，互联网上的博客，论坛，商贸平台上千万，发布到那么几十个平台上的广告信息，在浩瀚的信息海洋里显然很容易被淹没，而要大部分覆盖这些平台，显然需要大量的人力和时间来发布，这不是一般的企业所能承受的。营销软件的出现，很好地解决了这一问题，用户可以通过多渠道了解您的产品，从而主动找上门，促成订单，提升销售额。性价比高，特别适合中小企业。
How to increase sales:
1. Strive to improve product quality
In order to have good sales volume, the company’s products must first be well made. The quality of the product is the most critical point. A product that cannot even guarantee the quality will not be favored by users. Even if it is popular for a while, it will cut off all retreats, such as Sanlu, which was once in the limelight. Therefore, if you want to increase sales, you must strictly control the quality.
2. Strive to provide good after-sales service
Selling products is not the end of the company’s sales, or it is just the beginning of sales. A good product is not only reflected in excellent quality, but also in high-quality after-sales service. If the after-sales service is in place and the user’s reputation is good, it will bring you more users, which can also be regarded as a small-scale word-of-mouth marketing.
3. Large-scale media advertising
The effect of advertising is undoubted. The most significant one is TV advertising. The sky-high advertising costs during prime time are enough to prove its value; followed by print advertising, paper media advertising and bus advertising. This type of advertising has a significant effect on increasing sales, but the huge advertising costs are also unaffordable for some companies, especially for small and medium-sized enterprises with relatively short funds. It is obviously unrealistic to vigorously lay out. Therefore, the more such advertisements, the better. You should do what you can.
4. Internet advertising
Compared with the media advertising mentioned above, Internet advertising costs relatively less and the effect is also significant. Therefore, more and more companies are beginning to use Internet advertising to sell their products. Internet advertising includes paid advertising on website platforms, and some do bidding ranking. The cost of Internet advertising is less than that of media advertising, but for small and medium-sized enterprises, the cost is still high, and there is a disadvantage of Internet advertising. The more you spend in the later stage, the less significant the effect will be.
5. Free Internet marketing promotion
Free Internet marketing promotion refers to a commonly used method. The specific method is to publish advertising information for free on major trade platforms, large forums, blog platforms, and user mailboxes. This method is particularly favored by small and medium-sized enterprises because it costs less and only takes a certain amount of time and manpower. However, there will still be various problems in the specific implementation process. There are tens of millions of blogs, forums, and trade platforms on the Internet. Advertising information posted on dozens of platforms is obviously easily drowned in the vast ocean of information. To cover most of these platforms, it obviously requires a lot of manpower and time to publish, which is not something that ordinary companies can afford. The emergence of marketing software has solved this problem well. Users can learn about your products through multiple channels, so they can actively come to you, promote orders, and increase sales. It is cost-effective and especially suitable for small and medium-sized enterprises.
