Invoicing Software for Web Developers

In the US, the Bureau of Labor Statistics' Occupational Outlook Handbook (page last modified August 27, 2026) says "Web developers create and maintain websites." It also says "They build particular types of websites, such as ecommerce, news, or gaming sites, to fit clients’ needs."

That work turns into a few kinds of invoices: a fixed fee for a build, hours for work whose scope isn't set in advance, and a monthly fee for maintenance after launch. Your contract with each client sets which of these apply, so check its terms before you bill.

Billed's features page says "Yes your clients can approve or reject your estimates online." and "Convert your estimate to invoice with a single click after getting approval from your client." Billed's estimating page says you can "Attach important files and images with your estimates."

For a fixed build fee, Billed's projects page says "Track your flat rate projects with Billed." and "Invoice your client for the project from the dashboard whenever you want." For hourly work, Billed's time tracking page says "Create an hourly rate project, set its hourly rate, and Billed tracks the charge for each task as you log it." It also says you can "Create timesheets from the time you and your team have tracked to see how the team is spending its time, and export them when a client or your accountant needs a copy."

For monthly maintenance, Billed's invoice software page says you can "Choose the billing frequency (daily, weekly, monthly or yearly)", and "Billed creates the invoices automatically and either sends them or saves them as drafts for you to check." For clients abroad, the same page says you can "Invoice customers in multiple currencies, choosing a different currency for each invoice or customer."

These are sample figures. A developer quotes a fixed fee of $6,000.00 for a small business website. The client approves the estimate online, and the developer converts it into an invoice.

The contract sets three payments: 40% to start, 30% when the design is approved and 30% at launch. 40% of $6,000.00 is $2,400.00, and 30% is $1,800.00. The invoice gets three scheduled payments, and Billed's help center says "Add a percentage or flat amount and the due date for each installment." $2,400.00 + $1,800.00 + $1,800.00 = $6,000.00, which matches the invoice total, as Billed's help center requires. The fee and the percentages are examples, not suggested terms.

Billed's help center says "A payment schedule lets you add a payment plan to the invoices." and "You can make unlimited installments. However, the sum of all installments should be equal to the total balance of the invoice."

Billed's mobile app page says "Invoices carry a pay button when Stripe or PayPal is connected, so clients can pay by card the minute they receive it." Billed's invoice software page says "When a client pays by check or cash, record it as an offline payment so all your income is in one place." and "Set a due date on each invoice so your client knows when to pay." Billed's help center says "You can set a schedule of payment reminders before and after the invoice's due date."

Billed's invoice software page says "Invoice reports show which invoices are paid, partially paid or past due, and you can see who owes you money and send them a payment reminder." For services you bill again and again, the same page says you can "save the products and services you sell so you can pull them into an invoice instead of retyping them."

How you report your income, and whether sales tax applies to what you sell, depend on where you work and what you deliver, so ask your accountant.
