The reimbursement gap: payroll is due before the claims pay.

A busy practice can be short of cash precisely because it is busy. Here is how to measure the gap between services billed and money in the account, and when funding it makes sense.

The short answer

Updated October 13, 2026 · Merchant Fund Express

A practice bills today and is paid later, on each payer’s own clock. Payroll, rent and supplies run on a fixed calendar. When volume grows, a new payer is added, or a payer slows down, the practice can be profitable on paper and short in the bank account for weeks.

Funding can bridge that gap, but only once you know how big it is, how long it lasts, and whether it repeats. A one-time slowdown and a permanent mismatch call for different answers.

Read the aging, not the billing total

Billed charges are not cash. What matters is what has been collected, and how many days it took. Work from your practice management system’s aging report, grouped by payer type, never by individual account. No funder needs patient-level detail, and you should not send it.

Aging bucketWhat usually sits thereHow to treat it
0 to 30 daysMost recent claimsExpected, if clean
31 to 60 daysNormal for many commercial payersWatch for growth here
61 to 90 daysSlow payers, rework, missing informationUsually the source of the squeeze
90+ daysDenials and appealsDo not count on it for payroll

If the 61 to 90 day bucket is growing month over month, the gap is getting wider, and borrowing simply covers it for longer.

A dated cash example (illustrative)

A practice with about $95,000 a month in collections pays staff on the 1st and 15th, about $31,000 per run. A large commercial payer changes its processing and slows from roughly 30 to roughly 55 days for six weeks.

DateEventAmountBalance
Oct 1Payroll$31,000 out$42,000
Oct 1 to 14Collections, slower payer delayed$33,000 in$75,000
Oct 5Rent and supplies$18,000 out$57,000
Oct 15Payroll$31,000 out$26,000
Oct 15 to 31Collections still delayed$29,000 in$55,000
Nov 1Payroll$31,000 out$24,000
Nov 5Rent and supplies$18,000 out$6,000
Nov 15Payroll due, delayed claims not yet in$31,000 out−$25,000
Nov 20 to 30Delayed claims arrive$58,000 in$33,000

The gap peaks at about $25,000 for roughly five days in mid-November. That is a short, defined need. A small draw on a line of credit, repaid when the delayed claims land, fits it far better than a large lump sum with months of payments.

All figures in worked examples are illustrations of the arithmetic, not offers or quotes. Real terms depend on your file and the funder.

The affordability screen

Is the slowdown temporary and explained, for example a payer system change? Or is the payer mix shifting permanently toward slower payers?
Can the practice carry the payment after the claims arrive, using normal monthly collections, not the catch-up month?
Is overhead growing faster than collections? If so, funding hides a margin problem instead of solving a timing one.
Will the bank account still show a healthy average daily balance after the payments start?

If the answer to the second question is no, the practice needs a billing or cost fix, not funding.

When not to borrow

Denials are rising because of coding or documentation problems. Fix the billing process first; money only delays the problem.
The gap is permanent because reimbursement rates fell. That is a pricing and cost question.
You are relying on 90+ day receivables to repay. Those are uncertain by definition.

In those cases, talking to your billing team or clearinghouse will do more than any funding product.

Which product fits

Short, repeating gaps suit a business line of credit, available on the first tier of our published requirements (three years in business, 650 credit and more). A one-time catch-up is often handled with working capital. For the wider view of practice funding, see the medical practice hub and the medical practice cash flow guide.

What to send, and what not to send

Send: three months of business bank statements as PDFs, a summary aging report by payer type, and your payroll calendar
Do not send: patient names, claim-level detail, explanation-of-benefits files or anything with protected health information

When you are ready, apply in about five minutes. Starting the application uses a soft credit pull.

Common questions

Do funders want my claims data?

No. A file is read from business bank statements and, at most, a summary aging report by payer type. Never send patient-level information.

Can I borrow against insurance receivables?

Some funders offer receivable-based products, but most practice files we see are read on deposits. The amount depends mainly on your collections and existing obligations.

How do I know if the gap is temporary?

Compare your aging buckets month over month. If one payer explains the growth and the cause is known, it is likely temporary. If every payer is slowing, it is not.

Is a line of credit better than a lump sum here?

For short, repeating gaps, usually yes, because you draw only what payroll needs and repay when claims land.
