Web Developer Invoicing: Code Deliverables, Repositories & Retainers

Software engineers, frontend specialists, and full-stack web developers require precise invoices that reflect project milestones, code repository releases, and technical maintenance retainers.

#

1. Invoicing Project Milestones & Sprints

- Phase 1 (Kickoff & Architecture): 30% to 50% upfront deposit before commencing database architecture or Figma conversion. - Phase 2 (Beta Staging Deployment): Mid-project draw payable upon deploying functional code to a password-protected staging server. - Phase 3 (Production Launch & Handoff): Final balance due prior to transferring production domain DNS records, cloud server credentials, or GitHub repository ownership.

#

2. Managing Maintenance Retainers & API Overage

For ongoing client engagements, itemize monthly server monitoring, security dependency patches, automated database backups, and pre-allocated technical support hours. Specify that unused monthly retainer hours do not roll over to subsequent billing cycles.

Frequently Asked Questions

Is custom software development labor subject to US sales tax?

In most states, custom programming and software labor is considered exempt professional service, whereas pre-written off-the-shelf software is taxable.

What is the best way to invoice milestone-based software projects?

Invoice in 3 to 4 sequential milestones: 25% project kickoff, 25% staging preview, 25% user acceptance testing, and 25% final code deployment.

Should hosting and third-party SaaS fees be billed on the same invoice?

Keep recurring monthly cloud hosting or domain maintenance fees on a separate recurring retainer invoice for cleaner accounting.
