Frequently Asked Questions

What is the difference between recourse and non-recourse factoring?

Recourse factoring requires the contractor to buy back invoices if clients don't pay, while non-recourse factoring (like Resolve Pay's model) eliminates this risk by having the factoring company assume the credit risk. Non-recourse protection is particularly valuable in construction where payment disputes and delays are common.

How quickly can mechanical contractors get paid using modern invoice financing solutions?

Modern solutions provide same-day to 24-hour funding after approval, compared to traditional factoring that may take several days. Platforms like Resolve Pay offer 24-hour funding cycles, while others can provide funding within 24-48 hours of approval, enabling mechanical contractors to maintain consistent cash flow for materials, labor, and overhead expenses.

What advance rates are typical for mechanical contractor factoring?

Advance rates typically range from 80-100%, with some providers offering the full invoice value upfront and others providing 80-95% initially with the balance released after client payment (minus fees). Higher advance rates provide more immediate working capital to cover materials, labor, and overhead expenses common in mechanical contracting projects.

How does AI automation specifically benefit a mechanical contractor's AR department?

AI automation reduces manual reconciliation for complex invoices, accelerates credit decisions from days to seconds, and automates payment reminders and collections management. Platforms like Resolve Pay use AI to map and sync transaction data in real time, reducing administrative burden while maintaining professional customer relationships throughout the payment cycle.

What should mechanical contractors look for when choosing a factoring company?

Key considerations include advance rates (80-100%), funding speed (24-48 hours), recourse vs. non-recourse terms, construction industry expertise, fee transparency, contract flexibility, and ERP integration capabilities. Mechanical contractors should prioritize providers who understand construction-specific challenges like retainage, progress billing, and lien complexities while offering competitive terms that support healthy cash flow management.
