Common questions

Frequently asked questions

What is a good DSO for a contractor?

It depends on work type. Residential service should be 20–25 days, residential install 30–35, commercial service 35–40, and commercial project 45–60. If your DSO is higher, cash is trapped. This calculator estimates how much.

Why is my business profitable but cash is tight?

Profit on paper does not fund payroll if cash is sitting with customers. Common causes: invoicing days or weeks after work is complete, no follow-up on aging AR, missed change orders, and customer concentration where one slow payer backs up everything. This calculator sizes the exposure.

How do I speed up collections as a contractor?

Invoice the same day work is complete. Follow up at 15, 30, and 45 days with escalating urgency. Bill change orders immediately. Track DSO by customer and work type. The Business Checkup verifies which of these are actually causing your cash drag.

How much does slow invoicing cost?

Every day of invoice delay ties up one day of revenue in cash you cannot use. On $200K/month revenue, a 14-day invoice delay versus same-day means roughly $93K in extra cash trapped. This calculator factors in your specific invoice timing.

Is this calculator accurate?

It provides a directional estimate of cash above target receivables, plus aging risk and change-order exposure. The real answer depends on your customer mix, contract terms, and billing process. The Checkup verifies the actual cause.
