Milestones that blur
Design was approved in a meeting, development “mostly” finished, the launch slipped. Which milestone is due, and has it been billed?
Phase 2 shipped in September; its invoice went out in November.

What is billing software for web developers?
Billing software for web developers covers both halves of the business: the project, billed in milestones, and the long tail of maintenance, hosting and support that follows it, billed every month or year.
PikZiy Books handles both with the same invoices, and a built-in way to bill retainers that keep going.
WHERE WEB WORK GOES UNBILLED
Launch day is the easy part. Billing the next three years isn't.
Maintenance for free
The site is live and the client keeps asking for small changes. Nobody set up the monthly plan.
Four hours a month of updates, unbilled for a year.
Hosting renewals on your card
You pay the hosting, domain and plugins every year and forget to bill them back.
₹18,000 of renewals you paid for, for a client you no longer hear from.
BUILD, LAUNCH, MAINTAIN
From the first milestone to the monthly plan.

QUESTIONS
Asked, and answered.
What is billing software for web developers?
Billing software for web developers quotes a website build, bills it in milestones, and then keeps billing the maintenance plan every month or year without anyone remembering to. It should handle GST with the right SAC codes, clients in other states and abroad, and the costs of hosting and tools.
How should I bill a website project?
Quote the build in phases, such as design, development and launch, with the payment due at each. When the client accepts, create an invoice from the quote for each milestone. Our guide to billing clients for website design has an example.
How do I bill a monthly maintenance or AMC plan?
Invoice the first month of the plan, then turn it into a subscription on Business. It invoices the client every month, quarter or year, and can issue and email each invoice on its date. Use an end date for a fixed-term annual maintenance contract.
Which SAC codes do web developers use?
Website design and development usually falls under SAC 998314 (IT design and development services), and hosting under 998315. Maintenance and support plans are often billed under 998316 (IT infrastructure and network management). All at 18% GST. Save them on your items and they fill in on every invoice; check the right code for your work with your CA.
What should a website maintenance plan cost?
Enough to pay for the hours you expect each month, a buffer for urgent fixes, and the hosting, domain, plugins and backups you pay for. The calculator on this page works it out from your own numbers.
Can I bill for extra development hours?
Yes. Add the hours as the quantity, with “hours” as the unit and your rate as the price, as a separate line or on its own invoice. There is no timer, so keep your hours in the tool you track them in now.
Can I invoice clients outside India?
Yes, in US dollars, euros, pounds and other currencies, with the place of supply shown as outside India and your LUT declaration in the notes. On Growth and above, exports go into the EXP table of GSTR-1.
My client deducts TDS on development work. At what rate?
Usually 10% if the work is treated as professional services and 2% if treated as technical services, once the year's payments to you cross ₹50,000. Record what you received and the TDS kept back with its section when you record the payment. See TDS on professional invoices.
Can I track hosting and software I pay for?
On Growth and above. Record hosting, domains, plugins and SaaS tools as expenses, set the monthly and yearly ones to repeat, and see the month by category. In foreign currency too.
Which plan does a web developer need?
Starter covers quotes, milestone invoices, payments and reminders. Growth adds expenses and GST returns. Business adds maintenance plans that invoice themselves, client statements and double-entry books.
Launch the site. Let the plan bill itself.
