Billing and Payment

Depending on the timescale or size of the project I may ask for upfront, and/or interim payments, but will always be clear about when and how much will be payable.

I issue invoices electronically, and payment is due within 14 days of the date of invoice. I’d like to give you all the time in the world, but alas. Payment can be made by BACS, Paypal or Stripe. International payments are welcome and clients agree to cover the cost of any fees involved. For international projects, the invoice amount is calculated with the exchange rate on the day of invoice. For that reason initial estimates are subject to change over time.

I don’t currently charge VAT.


Quotes are valid for 30 days from the date of issue.


Your server must be running up-to-date versions of PHP and MySQL. I will need access to the server control panel, details of which must be given to me well in advance of a proposed launch date.

Data backup

I make daily, off and onsite backups of computer data and an initial backup of sites I build. Subsequent, automatic backup plans can be arranged.

Development terms

I build standards compliant-sites, that are accessible and viewable across a broad range of devices.

I support the same browsers as Google. You can see what they are here.


I currently have subscriptions with two services, Adobe Fonts and Fonts.com, who between them serve more webfonts than you can shake a font-face at. I regularly use these in my projects. Clients understand that use of these fonts is governed by Typekit’s and Fonts.com’s own support terms.


I will fix bugs free of charge for 30 days after the agreed launch date. But I’m a nice guy and won’t leave you in the lurch after that – just understand that some fixing may be due to factors beyond my control, and therefore billable.


My work is very important to me and I like to share it with people. The client allows use of their name and a description of the work undertaken in publicity material I generate. I may also use images of completed work for my online portfolio at www.davidabbott.xyz except where the client requests otherwise.
