Payment Gateway Reserve: How Much Working Capital Is Locked?

A payment gateway reserve is money from your own sales that the gateway keeps back as protection against chargebacks and refunds. For a business doing ₹30 lakh a month online, a 10% rolling reserve held for 90 days plus a two-day settlement lag can quietly lock up ₹11 lakh or more, which you then have to fund from your own capital or your bank limit. This guide shows how to estimate that number, what the rules say, and how to negotiate it down.

The figures below are illustrative. Your actual reserve percentage, hold period and triggers are in your merchant agreement and the gateway's dashboard.

The four ways a gateway holds your money

Gateways usually impose reserves on new merchants, high-ticket or "future delivery" businesses (travel, events, education, pre-orders, subscriptions), and accounts with high chargeback or refund ratios.

What RBI rules say as of October 2026

Online payment gateways in India operate as payment aggregators (PAs) under the Reserve Bank of India (Regulation of Payment Aggregators) Directions, 2025, issued on 15 September 2025. The points that matter to a merchant:

• Escrow: a non-bank PA must keep the money it collects for merchants in a separate escrow account with a scheduled commercial bank. Your unsettled sales and reserve are therefore not the PA's own money.
• Settlement timelines are contractual: the Directions leave settlement timing to the PA-merchant agreement, but that agreement must be fair, equitable and transparently state the settlement timelines.
• Disputes and refunds: the PA must have a policy for chargebacks, disputes and refunds with timelines, and refunds generally go back to the original payment method.
• Merchant grievance officer: the PA must appoint an officer to handle merchants' issues, with an escalation matrix shown on its website.

RBI does not set a reserve percentage or hold period. Those are commercial terms, which is why they are negotiable. For how fees, GST and refunds show up in each payout, see our guide to reconciling payment gateway fees and GST.

Formula: estimating the cash locked up

Locked cash = (Daily gateway sales × Reserve % × Hold days) + (Daily gateway sales × Settlement lag days) + Fixed deposit + Disputed amounts on hold

Use average daily sales through the gateway, not total business sales. If your sales are seasonal, run the formula for both a normal month and your peak month.

Worked example: ₹30 lakh a month online

Sharma Coaching sells course fees online. Illustrative terms in its agreement:

• Gateway sales: ₹30 lakh a month, or about ₹1 lakh a day
• Rolling reserve: 10% of each day's settlement, released after 90 days
• Settlement: T+2
• Fixed security deposit: ₹2 lakh
• Chargebacks under dispute at any time: about ₹50,000

That ₹13.5 lakh is about 45% of one month's sales. If the gap is funded from a cash credit limit at an illustrative 11% a year, the carrying cost is roughly ₹13.5 lakh × 11% = ₹1,48,500 a year, on top of gateway fees.

The build-up phase

The reserve does not appear all at once. With nothing released until day 91, the balance grows by about ₹3 lakh a month: ₹3 lakh after 30 days, ₹6 lakh after 60 days and ₹9 lakh after 90 days. After that, each day's release roughly matches each day's new hold. New merchants often feel the cash squeeze in exactly this first quarter.

Growth makes it worse

If festive-season sales rise to ₹1.5 lakh a day, the reserve climbs towards ₹1.5 lakh × 10% × 90 = ₹13.5 lakh, an extra ₹4.5 lakh, plus ₹1 lakh more in transit. Growing online sales absorbs cash even when the business is profitable, a pattern explained in our guide to the cash conversion cycle.

Reading your merchant agreement

Find these clauses and note them in one place:

• Reserve percentage and whether it applies to gross or net settlement
• Hold period and the release schedule (daily rolling, monthly, or lump sum at the end)
• Triggers that let the PA raise the reserve or pause settlement (chargeback ratio, refund ratio, sudden volume spike, change in business model)
• Whether the reserve earns any interest (usually it does not)
• Conditions for review or reduction, and how long the reserve is held after you close the account
• Set-off rights: whether the PA can deduct chargebacks or fees from the reserve
• Dispute resolution: arbitration seat, governing law, notice period

What to ask the gateway

1. "Please share a reserve ledger showing each amount held and its release date."
2. "What chargeback and refund ratios must we maintain for the reserve to be reduced or removed, and when is the next review?"
3. "Can the reserve be replaced by a fixed deposit under lien or a bank guarantee?" A bank guarantee costs a commission, but it can be cheaper than locking up sales cash.
4. "Can settlement move from T+2 to T+1 once we have a clean history?"
5. "For future-delivery sales, can the hold be tied to delivery dates instead of a flat 90 days?"

Send these by email to your account manager and keep the replies. Written answers are what you will need if a release is delayed.

Telling your bank about the reserve

Lenders reviewing your working capital need will see sales in GST returns that have not reached your bank account. Explain the gap before they ask:

• Show the reserve and in-transit amounts as other current assets in your projected balance sheet and CMA data.
• Expect the bank to exclude the reserve from drawing power, since it is not a trade receivable from a customer. Ask how your bank treats it, in writing.
• Attach the merchant agreement, three to six months of settlement reports and the reserve ledger.
• If you are choosing between a working capital limit and a term loan to fund the gap, see working capital loan vs term loan.

Records to keep every month

• Gateway settlement reports and payout UTRs matched to bank credits
• Reserve ledger: amount held, date held, scheduled release, actual release
• Chargeback and refund reports with evidence submitted
• Merchant agreement and every addendum or email changing terms
• GST returns showing gateway sales, for matching with settlements

Common mistakes

• Planning cash on gross sales: budgeting as if every online rupee arrives in two days.
• Missing the build-up: a new gateway account starves cash for the first hold period even if sales are steady.
• Ignoring chargeback evidence: an unanswered chargeback is lost and can push your ratio past the reserve trigger.
• Not tracking releases: a release that was due and not paid is easy to miss without a ledger.
• Splitting volume blindly across gateways: each new gateway may start its own reserve, multiplying locked cash.

How to escalate a delayed release

1. Gateway support ticket with the reserve ledger entry, the release date in the agreement and your bank account details.
2. Merchant grievance officer / nodal officer of the PA, whose details RBI requires on its website. Give a clear deadline, such as 15 days.
3. If a bank is involved (for example, a bank-run gateway, or your bank not crediting a payout it received), complain to the bank's grievance cell. If it does not resolve the complaint within 30 days, or rejects it, file on cms.rbi.org.in under the Reserve Bank – Integrated Ombudsman Scheme, 2026 within 90 days. See bank not resolving complaint.
4. Non-bank PA: non-bank payment aggregators are not among the entities covered by the Ombudsman Scheme, 2026. A complaint lodged on the CMS portal may be routed to other RBI grievance arrangements, but a contractual dispute over reserve terms will usually be decided under the arbitration or jurisdiction clause in your agreement. Take legal advice before sending a formal notice.

Key takeaways

• A reserve is your own sales cash held back; estimate it as daily sales × reserve % × hold days, plus settlement lag, deposits and disputes.
• In the illustrative example, ₹30 lakh a month of sales locks up about ₹13.5 lakh.
• RBI requires escrow, transparent settlement timelines and a merchant grievance officer, but the reserve itself is a negotiable commercial term.
• Ask for a reserve ledger, a review date and alternatives such as an FD lien or bank guarantee.
• Tell your bank about the reserve upfront and fund the gap with the right working capital product.
