This is the reason why we\u2019ll start from the very beginning, explaining what an invoice is and how you should deal with HVAC invoices.<\/p>\n\n\n\n<p>An HVAC invoice is a detailed receipt that documents any transaction between clients and businesses. <\/p>\n\n\n\n<p>You would usually give your client an invoice once the job is done to prompt them to pay you for the provided service.&nbsp;<\/p>\n\n\n\n<p>Remember to include any products or services you purchased on credit and to provide information on the available methods of payment. Also, don\u2019t forget to keep a copy of the invoice for yourself!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Three Types of HVAC Invoice<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"690\" height=\"460\" src=\"https:\/\/i0.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/round-gold-colored-and-silver-colored-coin-lot.jpg?resize=690%2C460&#038;ssl=1\" alt=\"round-gold-colored-and-silver-colored-coin-lot\" class=\"wp-image-14755\" srcset=\"https:\/\/i0.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/round-gold-colored-and-silver-colored-coin-lot.jpg?resize=1024%2C683&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/round-gold-colored-and-silver-colored-coin-lot.jpg?resize=600%2C400&amp;ssl=1 600w, https:\/\/i0.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/round-gold-colored-and-silver-colored-coin-lot.jpg?w=1050&amp;ssl=1 1050w\" sizes=\"(max-width: 690px) 100vw, 690px\" data-recalc-dims=\"1\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Flat Rate<\/strong><\/h3>\n\n\n\n<p>A flat rate invoice is quite easy to create, as you don\u2019t need to add many details relating to the price of labour, products and goods purchased or mileage &#8211; unless you\u2019ve taken a job outside of your service area. In that case, you should charge mileage.&nbsp;<\/p>\n\n\n\n<p>This kind of invoice bills the client one flat price, thus combining all the different costs into one.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Service Agreement<\/strong><\/h3>\n\n\n\n<p>Various HVAC jobs are not likely to be one-offs, especially when dealing with maintenance work. This is when service agreement invoices come in handy.&nbsp;<\/p>\n\n\n\n<p>The client is billed a flat rate in the form of a service plan, such as heating systems checkups, for example. Bills can be filed after each visit or periodically as monthly or annual packages.&nbsp;<\/p>\n\n\n\n<p>The cost of labour is usually included in the package but you can add some extra tasks when needed. Use a check-list for the services that are to be carried out. It will give consistency and quality to your regular work.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Parts and Labour<\/strong><\/h3>\n\n\n\n<p>Parts and labour invoices include the cost of labour, the parts and the time required to reach the place where the service will be provided.<\/p>\n\n\n\n<p>Be very careful when specifying the amount of time required for the job. Always invoice for time once the work has been carried out and include the time spent to get to the workplace.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How to Write an HVAC Invoice<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"690\" height=\"461\" src=\"https:\/\/i2.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/tyler-franta-iusJ25iYu1c-unsplash.jpg?resize=690%2C461&#038;ssl=1\" alt=\"smart_working_laptop\" class=\"wp-image-14756\" srcset=\"https:\/\/i2.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/tyler-franta-iusJ25iYu1c-unsplash-scaled.jpg?resize=1024%2C684&amp;ssl=1 1024w, https:\/\/i2.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/tyler-franta-iusJ25iYu1c-unsplash-scaled.jpg?resize=600%2C401&amp;ssl=1 600w, https:\/\/i2.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/tyler-franta-iusJ25iYu1c-unsplash-scaled.jpg?resize=1536%2C1026&amp;ssl=1 1536w, https:\/\/i2.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/tyler-franta-iusJ25iYu1c-unsplash-scaled.jpg?resize=2048%2C1368&amp;ssl=1 2048w, https:\/\/i2.wp.com\/www.invoiceberry.com\/blog\/wp-content\/uploads\/2020\/04\/tyler-franta-iusJ25iYu1c-unsplash-scaled.jpg?w=1380&amp;ssl=1 1380w\" sizes=\"(max-width: 690px) 100vw, 690px\" data-recalc-dims=\"1\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Choose the Best Invoice Type for Your Business<\/strong><\/h3>\n\n\n\n<p>Not all businesses are the same, that\u2019s why owners need to be particularly careful when choosing among flat rate, service agreement or parts and labour invoices.<\/p>\n\n\n\n<p>Weigh the pros and cons of each type and go for the most profitable choice!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Use a Clean Invoice Template or Software<\/strong><\/h3>\n\n\n\n<p>Professional-looking invoices are a great asset to your business.
