The short answer
A reserve is money the acquirer holds from your payouts to cover future chargebacks, refunds, or losses. Common on higher-risk merchant accounts. There are several types: rolling, upfront, and capped.
In plain English
When you process $100, you might expect $97 in your bank after processor fees. With a 10% rolling reserve, you'd actually see $87 — the remaining $10 is held for 90-180 days then released (assuming no chargebacks hit). Reserves protect the acquirer, not you. They function as a chargeback insurance policy the merchant pays for by foregoing immediate cash flow.
How it shows up in your business
- Cash flow hit: 10% reserve held 90 days = roughly 10% of one month's volume tied up at any given time. On $500k/mo that's $50k.
- Rolling reserve: a percentage of every batch held for a set period (typical: 5–20% for 90–180 days).
- Upfront reserve: flat dollar amount held at onboarding, released after N months of clean processing.
- Capped reserve: held until the total reaches a threshold, then new batches release as old ones roll off.
- Reserves can grow if chargeback ratio climbs. Acquirers reserve the right to increase reserves unilaterally.
Numbers to know
Typical reserve bands by vertical risk:
- Low-risk retail: often 0% reserve
- Subscription DTC: 5–10% rolling for 90–180 days
- Nutraceutical / supplements: 5–15% rolling for 90–180 days
- CBD / kratom / other regulatory-adjacent: 10–20% rolling for 90–180 days
- Peptides / SARMs: 15–25% rolling, sometimes higher
Reserves typically reduce after 6–12 months of clean processing. Negotiating the reduction usually requires a track record the acquirer considers meaningful — 6 months at 0.3% chargeback ratio with $500k/mo volume, for example.
Why multi-brand operators care
On a single merchant account across 4 brands, your reserve is on the pooled volume. That's more cash tied up than any one brand would justify on its own. On the other hand, 4 separate merchant accounts means 4 separate reserve pools + 4 separate negotiations. multiflow surfaces per-brand reserve contribution at the parent level so finance can see where the cash is tied up and make the reduction case to the acquirer when the numbers support it.
