Quick answer
An advance rate is the share of an invoice's face value a funder pays you upfront — commonly 80%–95%, and up to 97% on freight bills. The remainder is the reserve, which is not a fee but your own money held back until the customer pays, then released less the financing charge and any deductions. Advance rate and fee are separate levers, so the facility with the highest advance is not automatically the cheapest one.
Key takeaways
- The advance is cash today; the reserve is the rest of your invoice, released after collection.
- Reserves absorb short-pays, credit memos, returns and disputes — they are not an extra charge.
- Advance rates are set per customer and per invoice type, so one ledger can carry several different rates.
- Dilution, the gap between what you invoice and what is collected, is the strongest driver of your advance rate.
- Compare total cost: a 95% advance at 3% can be more expensive than an 85% advance at 1.25%.
What is an advance rate?
The advance rate is the percentage of an invoice's face value that a funder pays you at the moment of funding. At a 90% advance rate, a $40,000 invoice produces $36,000 in your account, usually within 24 to 48 hours of verification. Across receivables programs the normal band is 80%–95%, with freight bills reaching up to 97% because a delivered load with a signed proof of delivery is about as clean and short-dated as a commercial receivable gets.
Two things are commonly misread. First, the advance rate is not the cost of the facility — the fee is a separate number, and the two are negotiated independently. Second, the advance rate is rarely a single figure for your whole business. Funders set it per customer and per invoice type, so a ledger containing approved staffing timesheets, construction progress billings and medical payer claims may carry three noticeably different rates at the same time.
What is the reserve, and when do you actually get it?
The reserve is the remaining slice of the invoice — 5% to 20% in most facilities — held in your name until the customer pays. It is your money. It is not retained as compensation to the funder, and it is not a deposit you forfeit. Its purpose is to give the funder a cushion against the ordinary ways an invoice collects for less than its face value: a credit memo, a short shipment, a volume rebate, a pricing adjustment, a deduction for a damaged pallet.
When the customer's payment arrives, the funder applies it against the advance, deducts the accrued fee and any approved adjustments, and releases what is left. Release timing varies: some facilities release per invoice within a day or two of clearing funds, others batch weekly. That timing affects your working capital more than most people expect, so ask about it specifically.
A $60,000 invoice at a 90% advance and 1.5% per 30 days. The customer takes an $1,800 credit for a short shipment and pays the balance on day 30.
| Invoice face value | $60,000 |
|---|---|
| Advance at 90%, funded on day 1 | $54,000 |
| Reserve held | $6,000 |
| Customer remits, net of the $1,800 credit memo | $58,200 |
| Financing fee, 1.5% of face for 30 days | $900 |
| Reserve released to you | $3,300 |
You receive $57,300 in total. The $900 fee is the cost of the facility; the $1,800 shortfall is a commercial credit you granted to your customer, and it comes out of the reserve — which is precisely what the reserve exists for.
What advance rate should you expect?
Advance rates track how predictably an invoice converts to cash. Receivables with tight documentation, short payment cycles and little scope for deductions earn the highest advances. Receivables where the final collected amount is genuinely uncertain at the time of invoicing earn the lowest, because the funder is sizing the advance to the amount it expects to collect, not the amount printed on the invoice.
| Receivable type | Typical advance | What drives it |
|---|---|---|
| Freight bills with a signed POD | Up to 97% | Short cycle, standard paperwork, broker credit checked before dispatch |
| Staffing invoices backed by approved timesheets | 90%–95% | Client-approved hours leave little room for later deductions |
| Wholesale and distribution invoices | 85%–92% | Returns, shortages and promotional allowances create dilution |
| Manufacturing invoices for delivered goods | 85%–90% | Acceptance testing and warranty claims can delay payment |
| Federal invoices after assignment of claims | 85%–90% | Strong payer, but slower administration and strict notice requirements |
| Construction progress billings | 80%–85% of approved billings | Retainage is excluded entirely until the release conditions are met |
| Medical and insurance-payer receivables | Set against estimated net collections | Contractual adjustments and denials make billed charges misleading |
What raises or lowers your advance rate?
Advance rates are reviewed, not fixed for life. Most facilities start conservatively and improve once the funder has watched a few months of real collections. The levers below are the ones that actually move the number at a review.
- Dilution history — consistently low credits and deductions is the strongest argument for a higher advance
- Customer credit quality and the buyer's own payment record, measured in actual days rather than stated terms
- Concentration — a single buyer dominating the ledger usually attracts a cap or a lower rate on that account
- Invoice documentation: signed PODs, approved timesheets and clean acceptance records all help
- Invoice size and frequency, since many small invoices cost more to administer than a few large ones
- Recourse versus non-recourse, and whether credit insurance sits behind the buyers
- Your reporting discipline — timely aging reports and promptly posted credit memos build the trust that higher advances require
Why a higher advance rate is not automatically a better deal
Advance rate and fee are two different dials, and funders trade one against the other. Compare a $100,000 invoice at a 95% advance with a 3% monthly fee against the same invoice at an 85% advance with a 1.25% fee. The first puts $95,000 in your account on day one and costs $3,000 for 30 days. The second puts $85,000 in your account and costs $1,250. You received $10,000 less upfront and saved $1,750 in fees — and you still get the reserve back when the customer pays.
Whether that trade is worth it depends on what you do with the extra $10,000 for 30 days. If it funds a payroll you would otherwise miss or a supplier discount worth more than $1,750, take the higher advance. If it simply sits in your operating account, you have paid $1,750 for liquidity you did not need. The question to ask a funder is never only what is your advance rate — it is what will this facility cost me in total on my actual invoice profile and my customers' actual payment behavior.
How dilution is measured, and why funders watch it
Dilution is the percentage gap between what you invoice in a period and what you ultimately collect against those invoices. If you bill $1,000,000 in a quarter and collect $960,000 after credit memos, returns, discounts and write-offs, dilution is 4%. Funders calculate it from your own records during diligence and then track it continuously once the facility is live.
It matters because it sets the floor under your reserve. A funder will not advance 95% against a ledger that historically collects 92% of face value, because the reserve would not cover ordinary shrinkage. As a rough rule, the reserve needs to comfortably exceed your worst recent dilution plus accrued fees. This is also why reporting credits promptly is in your interest: unreported credit memos make measured dilution look volatile, and volatility is penalized more heavily than a consistently moderate number.
If your dilution is structurally high — a sector with routine chargebacks, say, or a buyer that deducts freight allowances as standard practice — say so during diligence and explain the mechanics. A funder that understands where the deductions come from will price them. A funder that discovers them in month three will cut your advance rate.
Short-pays, chargebacks and what happens to the reserve
A short-pay is a customer paying less than the invoice, usually with a stated reason. The reserve absorbs the shortfall, exactly as in the worked example above, and provided the deduction is legitimate the matter ends there. What complicates things is an unexplained short-pay: until it is reconciled, the invoice stays open, fees may continue to accrue, and the reserve stays locked.
A chargeback is more serious. Under a recourse facility, an invoice that goes unpaid past an agreed age — often 90 days — is charged back to you, and the funder recovers the advance from your reserve or offsets it against the next funding. If your reserve is thin at that moment, the recovery comes out of cash you were counting on. Keeping a realistic buffer in the reserve account, rather than drawing it to zero at every release, is a practical defense against that cash shock.
Separately, watch for reserve offsets you did not anticipate: accrued fees on other open invoices, administrative charges, or a reserve floor the agreement allows the funder to hold. Reconciling the reserve account monthly against your own ledger takes under an hour and catches errors long before they compound.
Questions to ask before you sign
Advance and reserve mechanics are where proposals quietly differ from one another. These questions surface the differences while you still have negotiating leverage.
- Is the advance applied to the face value of the invoice or to an adjusted eligible amount?
- Which balances are excluded from eligibility — retainage, aged invoices, intercompany sales, foreign buyers?
- How often is the reserve released: per invoice, weekly, or monthly in arrears?
- What dilution level triggers a review of my advance rate, and how much notice do I get?
- Can the advance rate improve automatically after a defined period of clean performance?
- What is the chargeback age, and is the recovery taken from reserve or from the next funding?
- Is there a minimum reserve balance the funder can hold back regardless of collections?
