Build a Agency Billing App with Glide

An agency billing app built with Glide gives marketing agencies, PR firms, and creative studios a billing system designed around agency economics — retainer billing, project overages, media buys, and production cost pass-throughs — that generic invoicing tools handle poorly. GlideApps Agency has built billing tools for agencies of all sizes that need to track billable hours by client and team member, manage retainer utilization, and bill accurately for every engagement type in their portfolio.

What does building a Agency Billing app include?

Every engagement includes discovery, data architecture, UI/UX design, development, QA, and post-launch support — not just a build-and-handoff.

Discovery & Architecture

Requirements mapping, data modeling, integration planning, and platform-fit assessment before a single screen is built.

UI/UX Design

Wireframes and interactive prototypes designed for your users — not generic templates. Optimized for mobile and desktop.

Development & QA

Built by certified Glide experts with enterprise experience. Rigorous testing across devices, roles, and data volumes.

Launch & Support

User training, documentation, and ongoing maintenance. We don't disappear after deployment.

Key features of your Agency Billing app

Retainer Utilization Tracking

Track hours and deliverables applied against each client's monthly retainer — giving account managers and clients visibility into retainer burn rate and available capacity before the billing period closes.

Project Billing & Scope Management

Manage fixed-fee project billing with milestone-based invoicing and scope change tracking so every project invoice is aligned with contracted deliverables and approved change orders.

Media & Production Cost Tracking

Record media placement costs, production vendor invoices, and third-party expenses against client campaigns for accurate cost pass-through billing with appropriate markup.

Team Time & Billing Rate Management

Configure billing rates by team member and role, capture time against client matters, and calculate invoice amounts from actual logged time — with blended rate reporting for client transparency.

Frequently asked questions about Agency Billing apps

How do we handle clients who consistently exceed their retainer?+

We build retainer overage tracking with configurable alerts when a client approaches their hour limit — giving account managers early warning to discuss scope expansion or bill overages at the agreed overage rate.

Can we bill different rates for different services within the same client retainer?+

Yes. We build service-type rate tables within each client agreement so strategy, creative, media, and reporting work is billed at the correct rate for each discipline — giving accurate blended rate calculations.

How do we handle rush fees and expedited delivery charges?+

We build rush rate triggers that apply a premium multiplier when projects are requested with less than standard lead time — capturing the additional revenue that rush work deserves.

Can we give account managers a billing summary they can send to clients each month?+

Yes. We build a client billing summary report that shows all work completed, hours logged by service type, expenses, and the current invoice amount — a transparency tool that reduces billing disputes.

How do we manage billing during agency team transitions or account handoffs?+

Complete billing history per client is stored in the app regardless of which team member is currently managing the account — so handoffs don't create billing gaps or lost invoice history.
