Running a glass business — whether residential glazing, commercial installation, auto glass, or glass fabrication — involves a billing cycle that most general invoicing tools don’t handle well. Glass jobs require detailed estimates with measurements and custom specifications, AIA-style progress billing for large commercial contracts, materials management tied to job costs, and field technician workflows that need to sync with the back office in real time.
You can easily track projects, estimates, and bills using the best billing software, and ensure that you are paid on schedule. They have functions that track billable hours and automatically convert bids to bills. Most provide client interfaces that make it simple to approve estimates so you can start working and getting paid.
The five tools below cover the spectrum from glass-specific management platforms to general-purpose invoicing tools. We cover what each does well, who it suits, and current 2026 pricing — so you can pick the one that best suits your kind of company.

Limitations to be aware of: the free plan supports up to 5 customers, with a cap on invoices per year. Larger client bases require upgrading to a paid Zoho Books plan.

5. HoneyBook
HoneyBook is an all-in-one client management platform that empowers professionals to streamline their business processes, impress clients, and ensure timely payments.

Contract Management — secure, ready-to-sign contracts managed entirely online, with eSignature included on all plans. Simplifies the negotiation and signing process for design and installation agreements.

Interactive Client Experience — customizable, interactive proposals let clients select services, review scope, eSign contracts, and make payments in one branded interface. This is HoneyBook’s primary differentiator from standard invoicing tools.

Which Billing Software Is Right for Your Glass Business?
Small independent glass shop or sole trader — Zoho Invoice (free, professional, handles quotes and invoicing efficiently) or Square Invoices Free plan (if you need fast on-site payment collection).
Residential glass installer with a field team (2–15 people) — GlassManager Lite or Professional plan. The job management, scheduling, materials tracking, and mobile app are purpose-built for your workflow. No general-purpose tool matches it for glazing operations.
Commercial glazing contractor doing AIA/progress billing — GlassManager Professional plan is essential. AIA-style billing and progress billing are specialized features that do not exist in Zoho, Square, or HoneyBook.
Auto glass or emergency glass repair (high volume, fast turnaround) — Square Invoices. The speed-of-payment statistics and mobile-first design match the operational tempo of this segment.
Architectural or decorative glass studio, custom glass designer — HoneyBook. The branded proposal experience, contract-to-payment workflow, and client portal create the professional impression that design-oriented glass businesses need.
Large multi-location glass fabricator or distributor — NetSuite ERP. The only tool on this list that can handle multi-entity financial management, complex inventory across warehouse locations, and enterprise supply chain operations. Budget accordingly.
Conclusion
Choosing the right billing software for a glass business comes down to matching the tool to the operational complexity of your specific work. GlassManager is the only purpose-built solution for glazing operations and should be the first evaluation for any glass shop with a field team. For smaller operations and solo glaziers, Zoho Invoice’s free tier and Square Invoices’ fast payment collection offer genuine value without ongoing software costs. HoneyBook suits the design end of the glass market. NetSuite serves enterprise-scale operations with a budget to match.
Since GlassManager, Zoho Invoice, Square Invoices (free tier), and HoneyBook all offer free trials or free plans, test the tools that match your segment before committing to a subscription.
Frequently Asked Questions
What makes billing software for glass businesses different from general invoicing tools?
Glass businesses have billing requirements that general invoicing tools were not designed to handle. These include AIA-style progress billing for commercial glazing contracts (which requires certified payment applications with scheduled values and stored-to-date calculations), glass-specific estimating with custom dimensions and material specifications, materials management that tracks glass stock by type and thickness, and job costing that ties material consumption directly to project profitability. GlassManager is the only tool on this list that addresses all of these natively. General tools like Zoho Invoice and Square Invoices cover standard invoicing efficiently but lack these glass-industry-specific features.
Is Zoho Invoice still free in 2026?
Yes, Zoho Invoice remains free in 2026 for businesses with up to 5 customers and up to 1,000 invoices per year. There are no ads, no credit card required, and Zoho’s policy prohibits selling user data. The limitation is the 5-customer cap, which means it is best suited for glaziers with a small, stable client base — residential repair specialists, for example. Businesses with larger or growing client lists should evaluate Zoho Books (paid plans from approximately $15/month) or one of the other tools on this list.
Does HoneyBook still have a free plan in 2026?
No. HoneyBook eliminated its free plan in 2025 as part of a broader pricing restructure that increased subscription costs by approximately 89.5% across all tiers. As of 2026, HoneyBook starts at $36/month (billed monthly) or $29/month (billed annually) for the Starter plan. A 7-day free trial with no credit card required is available, and a 60-day money-back guarantee applies to paid subscriptions. Always verify current pricing at honeybook.com/pricing.
Is NetSuite ERP suitable for a small glass shop?
No. NetSuite ERP is an enterprise-grade system that starts at approximately $999/month for the base license, with additional per-user fees of approximately $99/user/month. For a small independent glass business, this represents a significant ongoing cost that is unlikely to be justified. Small and mid-sized glass shops should evaluate GlassManager (purpose-built for glazing), Zoho Invoice (free for small operations), or Square Invoices instead. NetSuite becomes appropriate for larger glass fabricators or distributors managing multi-location inventory, complex financial reporting across entities, and supply chain operations at scale.
What is AIA-style billing and which glass billing software supports it?
AIA-style billing (American Institute of Architects billing format) is a standardized payment application format used in commercial construction contracts. It requires contractors to submit periodic payment requests using AIA Document G702 (Application and Certificate for Payment) and G703 (Continuation Sheet), which track scheduled values, work completed to date, materials stored on-site, and retainage. For glazing contractors working on commercial construction projects, the ability to generate AIA-compliant payment applications is often a contract requirement. Of the five tools in this guide, only GlassManager’s Professional plan includes native AIA-style billing. General invoicing tools like Zoho Invoice, Square, and HoneyBook do not support AIA billing.
Can I use Square Invoices for glass business billing without a Square card reader?
Yes. Square Invoices works entirely digitally — you can send invoices by email or SMS, and clients pay online via credit card, Apple Pay, Google Pay, ACH bank transfer, or Cash App Pay. A Square card reader is not required to use Square Invoices. The card reader is only needed if you want to accept in-person card swipes or tap payments at the job site. Many glass businesses use Square Invoices exclusively for digital billing without purchasing any Square hardware.
