Know if you’re over- or under-billing

Subs are forced to finance jobs because they bill for work in place and get paid roughly 90 days later, creating an imperative to bill over costs. With Siteline, see if you’re billing in excess of cost on each project to ensure you’re billing enough each month.

Types of Billing Supported

Submit all types of bills to your client. Siteline can handle whatever billing your construction contract requires.

Lump Sum

Unit Price

Time & Materials

One-Off Invoices

Frequently Asked Questions

What is AIA® billing?

AIA® billing is a progress billing method common in commercial construction. Each month, a subcontractor reports how much of each work item is complete on the schedule of values. The pay app shows the amount due, minus retainage. It uses two standard forms, G702® and G703®. Many general contractors (GCs) require it. Read the complete guide →

What’s the difference between G702® and G703®?

G702® is the summary page. It shows the contract amount, work completed to date, retainage, and the amount due this period. G703® is the continuation sheet. It breaks the work into line items from the schedule of values, with the amount billed on each. Together, they make up one AIA® pay app.

Is there free AIA® billing software?

You can find free AIA® billing templates, but most are spreadsheets. You have to enter the math, taxes, and carry-over from past months by hand. Siteline isn’t free. Siteline automates your pay apps so you spend less time on billing and fewer pay apps get sent back for fixes. We price based on the volume of pay apps you'd bill each month through Siteline.
