Billing Software for Web Development Agency owners

Web Development Agency Billing Software

Web dev agency billing is a 3-mode hybrid: milestone-billed projects ($15k-150k builds), hourly retainers ($10k-50k/month for ongoing dev work), and monthly maintenance retainers ($500-3k/month for hosting, security, updates). Smarfle handles all three on one engine: milestone invoicing with payment-link approval, time-tracking-to-invoice conversion for hourly, and recurring auto-charge for maintenance. No more juggling Harvest + FreshBooks + Stripe Subscriptions and reconciling at month-end.

Why generic billing software fails web development agency owners

Generic billing tools weren’t built for web development agency. Smarfle was.

Step-by-step

How web development agency billing works in Smarfle

From the first touch to the closed loop. No missing pieces.

  1. 1

    Client signs the project scope at $60k for a 90-day build

    Account manager creates the project in Smarfle with 30/40/30 percent milestones. First invoice ($18k) generates and emails to client with a Pay Now link.

  2. 2

    Client pays the first milestone via Stripe Connect

    Client clicks the Pay Now link, enters card or ACH, payment runs. Owner gets instant notification. Project kickoff officially starts. Account manager marks the milestone complete and schedules the next.

  3. 3

    Developers log time against the project

    Lead dev logs 8 hours on Day 5 of the project. Time entry tags the project and the work order. For milestone projects, time tracks for internal margin reporting (not directly billed); for hourly retainers, time auto-converts to billable invoice line items.

  4. 4

    Mid-project change order captured

    Client asks for 4 additional features. Account manager creates a change order in Smarfle ($8k) with line items. Client signs in the portal. Change order auto-adds to the next milestone invoice or generates a separate invoice.

  5. 5

    Maintenance retainer auto-charges monthly after launch

    Project launches in Day 90. Account manager configures the maintenance retainer ($1,500/month for hosting + security + small updates). First charge runs the day of launch. Recurring auto-charge from then on.

  6. 6

    Quarterly per-client margin report

    Owner runs the per-client margin report. Each project shows revenue (milestones + change orders) minus internal labor cost (developer hours x loaded rate) minus any subcontractor expenses. Knows exactly which projects were profitable and which weren't.

Where web development agency billing breaks down

The friction every web development agency owner recognizes.

✕

Milestone billing requires manual invoice generation each time

$60k website project broken into 30/40/30 percent milestones. You manually create 3 invoices in FreshBooks at each milestone, manually request approval, manually chase payment. 15 minutes of admin per milestone times 12 projects per quarter equals 9 hours of admin you don't bill for.

✕

Hourly retainer billing requires time-tracking-to-invoice reconciliation

Developers log time in Harvest, account manager exports the CSV, manually builds the invoice in FreshBooks, sends to client. Two systems, one error point per invoice. Easy to under-bill (forgotten hours) or over-bill (double-entry).

✕

Scope creep is the silent killer of dev project margins

Client asks for 4 additional features mid-project. Developer builds them. Account manager never invoices because the change order process lives in Notion and never gets formalized. 15-25 percent of project revenue silently evaporates.

The math for web development agency owners

Recover 15-20 percent more project margin via formalized change orders

Dev agencies typically absorb 15-25 percent of project scope as unbilled creep. On a $60k project, that's $9-15k. Smarfle's portal-based change order workflow (client signs in the portal) gets 70 percent of historically-absorbed scope formally billed. Realistic recovery: $6-10k per major project.

Features powering web development agency billing

Each one a deep-dive in its own right.

Project milestone invoicing with Pay Now links

Configure multi-milestone projects with percentage-based billing (30/40/30 typical). Each milestone fires an invoice automatically with a Pay Now link via Stripe Connect. No manual invoice generation.

Time tracking with billable hours conversion

Developers log time per project on their phone or desktop. Hours auto-convert to invoice line items at the configured hourly rate for hourly retainers. For milestone projects, time tracks for internal margin reporting.

Learn more

Recurring subscriptions for maintenance retainers

Post-launch maintenance retainers auto-charge monthly via Stripe Connect. Failed charge triggers immediate alerts. Saved card management in the client portal so clients self-update without owner involvement.

Learn more

Per-job expense tracking for true margin

Subcontractor invoices, AWS hosting costs, third-party API fees all log as per-job expenses on the project. Smarfle reports show true project margin (revenue minus all costs) so you know which engagements were actually profitable.

Web Development Agency Billing Software CRM questions

Both options work. Configure milestones to fire by date (e.g. Project Day 30 = 40 percent invoice) or by manual trigger from the account manager (mark milestone Complete = invoice). Owner picks per project type.
Yes. Time entries tag as billable or non-billable. Reports show per-client billable hours (for invoicing) separately from internal hours (for team utilization metrics). Both feed margin analysis.
Configure the project as fixed-price for client-facing invoicing. Developers still log hours internally for margin tracking. Reports show fixed-price revenue vs hourly cost so you know if you under-quoted the project.
Generate a final partial-milestone invoice for work-to-date (Smarfle calculates pro-rated based on logged hours). Client pays, project closes, remaining contracted scope released. Audit trail tracks the resolution.
Yes. Stripe Connect supports 135+ currencies. Configure each client's invoice currency. Smarfle stores invoices in the client currency, owner sees reports in USD via daily FX conversion.
Smarfle tracks subcontractor invoices as per-job expenses on the project (for margin calculation). Actual subcontractor payment happens via your own ACH or wire process (not through Smarfle's Stripe Connect, which is for client-receivable payments only).
