Invoicing Software for Web Development Agencies
Web development agencies need invoicing that reflects project phases—from initial setup and design integration through feature development to ongoing maintenance. AgencyPro automates web development invoicing by tracking setup, development, testing, and maintenance separately, so you bill accurately for each project stage while managing retainer-based maintenance alongside project work.

Built for Web Dev Agencies
Web development agencies constantly toggle between milestone-based project invoices for new site builds and recurring monthly invoices for maintenance retainers, often for the same client — and manually reconciling feature work, bug fixes, and third-party hosting costs across both billing models leads to errors and delayed payments. A client paying $25,000 for a site build and $1,200/month for maintenance needs two distinct invoice streams running in parallel without double-billing for work that straddles the handoff from project to retainer.

Why Web Development Agencies Need Better Invoicing
Agencies building websites, web applications, and digital platforms using modern development frameworks.
The same client pays $25K for a site build and $1,200/month for maintenance, but manually managing both billing streams causes double-billing errors and delays
Feature requests that arrive mid-project blur the line between "in scope" and "change order," and unbilled scope creep eats into project margins
Hosting renewals, domain fees, SSL certificates, and third-party plugin licenses get forgotten on invoices because they are not tracked in the billing system
Bug fixes during warranty periods and paid post-launch support look identical in time logs but require completely different billing treatment
How Web Dev Agencies Use AgencyPro Invoicing
Professional invoicing with time-to-invoice automation, multiple payment gateways, and branded invoice delivery.
Runs project milestone invoices and monthly maintenance retainers in parallel for the same client without cross-contamination between billing streams
Flags change requests during active development and generates supplemental invoices before the additional work begins, protecting project margins
Passes through hosting, domain, SSL, and API subscription costs as recurring line items on maintenance invoices with optional markup
Tags development hours as warranty (non-billable) or paid support (billable) so post-launch work gets invoiced at the correct rate automatically
Key Benefits for Web Dev Agencies
Sprint & Milestone Invoicing
Bill web development projects at agreed milestones—wireframe approval, design sign-off, development completion, launch—with tracked hours reported alongside each milestone payment.
Maintenance Retainer Billing
Automatically generate monthly invoices for website maintenance retainers covering updates, security patches, backups, and hosting management separate from new development work.
Feature vs. Bug Fix Separation
Clearly distinguish invoicing for new feature builds, enhancements, and integrations from bug fix and technical debt resolution work at appropriate rates.
Third-Party Cost Pass-Through
Separate hosting fees, domain renewals, SSL certificates, and third-party plugin or API subscription costs from development service fees on client invoices.
How It Works
Track build hours and maintenance hours on separate ledgers
Developers tag time against project milestones (wireframes, dev, launch) or maintenance categories (updates, security, bug fixes) as they work
Invoice milestones at sign-off, maintenance monthly
Project invoices trigger at wireframe approval, development complete, and launch while maintenance invoices auto-generate on a monthly schedule with tracked hours included
Pass through hosting and tools with zero manual effort
Recurring third-party costs like hosting, CDN, and premium plugins populate on maintenance invoices automatically each billing cycle
Frequently Asked Questions
A client's site build finishes and transitions to a maintenance retainer. How does billing handle the handoff?
The project invoice closes with the final launch milestone payment, and the maintenance retainer begins on a separate billing track the following month. There is no gap or overlap. The client sees the project close on one invoice and the first maintenance charge arrive on schedule, with a clear description of what the retainer covers versus what was included in the build.
Mid-project feature requests keep expanding scope. How do we bill for those without derailing the project budget?
Tag new feature requests as change orders in AgencyPro. Each generates a mini-estimate with projected hours and cost. Once the client approves, the change order hours track separately from the original project budget, and the additional charges appear as a distinct supplemental invoice or added section on the next milestone bill.
We manage hosting for 40 clients. Can those recurring costs appear on invoices automatically?
Set up each hosting plan, domain renewal, and SSL certificate as a recurring pass-through item in AgencyPro. Every monthly maintenance invoice auto-includes these costs alongside tracked support hours, saving your team from manually adding infrastructure charges to 40 invoices each billing cycle.
We offer 30 days of free bug fixes post-launch. How do we track that separately from paid support?
Create a warranty period in AgencyPro that flags bug fix hours during the first 30 days as non-billable. After the warranty expires, identical work automatically bills at your support rate. The client's first paid maintenance invoice clearly marks the transition, and your team doesn't need to remember to flip a billing switch.
