Custom quote — based on project volume/value
Pros
- Completely eliminates math errors on subcontractor schedules of values
- Automates lien waiver generation and electronic signature tracking
- Prevents subs from billing for unapproved change orders
Cons
- GC-centric; subs just use it to submit to the GC, not to manage their own top-level billing
- Pricing model can be expensive for mid-size firms with lower volumes
Recommendation: The absolute best choice for commercial GCs who want to eliminate the headache of chasing down sub pay apps and lien waivers at month-end.
Knowify
From $149/month (varies by user count and tier)
Pros
- Easiest platform for turning an estimate into an AIA G702/G703 format
- Exceptional integration with QuickBooks Online
- Manages complex change orders and incorporates them into progress bills seamlessly
Cons
- Lacks some enterprise-grade routing features needed by massive GCs
- QuickBooks Desktop integration is not as robust as the QBO connection
Recommendation: Our top recommendation for subs and trades who use QuickBooks Online but need to generate professional, accurate progress bills for their GCs.
Procore (Project Financials)
Custom quote — percentage of construction volume
Pros
- Unifies project management, field communications, and financials in one massive platform
- Handles extremely complex, multi-tiered approval routing for large projects
- Procore Pay functionality streamlines the actual movement of funds
Cons
- Very expensive implementation and annual cost
- Can be overkill and too complex for simple, quick-turn projects
Recommendation: The gold standard if you have the budget and need a unified system where billing is directly tied to RFIs, field daily logs, and massive project budgets.
Buildertrend
From ~$399 to $999+/month
Pros
- Phenomenal client-facing portal that makes homeowners comfortable approving bills
- Seamlessly handles cost-plus, flat-rate, and milestone billing structures
- Excellent handling of homeowner selections, allowances, and related change orders
Cons
- Schedule of Values formatting isn't as rigidly AIA-compliant as commercial tools
- Monthly subscription cost can add up as you add modules and users
Recommendation: If your clients are homeowners rather than commercial developers, Buildertrend’s presentation, client portal, and integrated payments make it the best billing tool on the market.
AIA Contract Documents (Software)
Per document ($40+) or Unlimited Annual (~$1,100+/yr)
Pros
- 100% legally compliant, official documents that banks and architects will never reject
- Ensures you are using the most legally up-to-date phrasing and structure
- Good cloud-based editor prevents the formatting nightmares of old PDF versions
Cons
- It is purely a document generator, not a financial system—no sync to accounting
- Requires manual data entry for previous application numbers, retainage, etc.
Recommendation: Best used as a supplementary tool if your architect or lender strictly requires a watermarked, authentic AIA document and won't accept a standard software-generated equivalent.
