Cash flow problems in eCommerce are almost always timing problems, and there are three distinct ones. Money you have earned has not arrived yet. Money you owe suppliers is due before the stock sells. Or a slow month collides with a repayment that does not care.
Each has a different fix, and using the wrong one is expensive. Everything below was read from each company's own site, and from Walmart's seller documentation, on 6 August 2026.
Gap one: the money exists, it just has not arrived
This is the most common and the most misdiagnosed. Marketplaces hold new seller funds, and the terms are stricter than most sellers expect.
Walmart holds a rolling portion of new US seller payments for up to 14 days, and the hold ends only once 90 days have passed since your first shipped order and you have received $7,500 in payments. Non-US sellers face up to 21 days on the same conditions. Payments do start arriving before then: you could receive payments as soon as 30 days after your first sale.
Both conditions have to be met. A seller who hits $7,500 in week three still waits out the ninety days.
| Gap | What fixes it | What it costs you |
|---|---|---|
| Earned money not yet paid out | Payout acceleration (Payability) | Daily fees on money you would have received anyway |
| Supplier payment due before stock sells | Invoice or payables funding (Clearco Invoice Funding) | A fee, plus the discipline of a payment schedule |
| Slow month against a fixed repayment | Sales-linked repayment (Onramp Funds variable, Shopify Capital) | Less in a slow month, more in a strong one |
| Recurring, unpredictable gaps | A revolving facility (Fundbox, Onramp rolling cash line) | Availability you pay for whether or not you draw |
Payability is built for exactly this gap. It advances marketplace earnings for Amazon and Walmart sellers, paid out daily rather than on the marketplace schedule, and qualifies on marketplace sales history and performance. It runs no credit checks, though it does perform a standard background check of public records.
Be clear about the trade. The daily payout program carries daily fees for advancing sales, and optional fees may apply for transferring advanced funds to a bank account. You are paying to move your own money forward by a couple of weeks, so the honest comparison is the annualised cost of that acceleration, not a comparison against a funding fee.
Gap two: suppliers want paying before the stock sells
This one is not solved by general working capital, or rather it is solved expensively. The targeted fix pays the vendor directly.
Clearco offers an Invoice Funding option that covers vendor invoices upfront without tapping into your cash reserves. It takes no collateral, asks for no personal guarantees, allows early payment without penalty, and uses capped weekly payments.
The bar is the problem for most readers: 12 or more months of consistent revenue above $100,000 USD per month. Below roughly $1.2M a year this is not available, whatever a comparison table tells you. An earlier version of this page also described Clearco as underwriting on advertising performance with rates varying by ad spend. Clearco's current site does not describe that model at all.
Gap three: a slow month against a repayment that does not flex
This is where structure matters more than price, and it is the difference between funding that helps and funding that compounds the problem.
Shopify Capital repayment is a fixed percentage of daily sales, taken only on days the store makes sales, with a maximum term of 18 months and 2 minimum payments applying. Funding arrives in as quick as two business days once approved, with offers up to $2M. It requires at least 90 days selling on Shopify plus policy compliance and is limited to select merchants in the US, Canada, the UK and Australia. One correction: an earlier version of this page said Capital is limited to stores using Shopify Payments. That is not among Shopify's published requirements.
Onramp Funds publishes three structures, and the choice between them is exactly this question. The variable option repays as a share of sales that moves with revenue, so a slow month collects less. The fixed option repays weekly or every two weeks over one to twelve months, which is cheaper on predictability and worse on a bad month. The rolling cash line is a revolving capacity that grows with sales and can be drawn as often as every two weeks.
Requirements are a legal US business entity, at least $10,000 in monthly sales and at least 6 months of selling history, with no personal credit check, across nine platforms: Amazon, Shopify, TikTok Shop, WooCommerce, BigCommerce, Squarespace, Walmart, Shopline and Stripe. There is one transparent fee with no hidden costs and no equity is taken.
Gap four: it happens every quarter
If the same gap opens repeatedly, a one-off advance is the wrong instrument. A revolving facility exists to be drawn and repaid.
Fundbox publishes up to $250,000 in funding with flexible repayment terms and no early repayment fees. It publishes no eligibility criteria on its homepage, so whether you qualify is a question you have to ask directly. Onramp Funds' rolling cash line serves the same shape of need for sellers on its supported platforms.
Diagnose before you finance
- Work out the length of your gap in days. Time from paying the supplier to receiving the payout. That number, not the size of the offer, tells you which structure fits.
- Separate delay from shortfall. If the money exists and is merely held, acceleration is cheaper than financing. If it does not exist yet, acceleration does nothing.
- Model the bad month before you sign. Take your worst month in the last year and apply the repayment structure to it. A percentage of sales shrinks. A weekly payment does not.
- Do not stack blindly. Two facilities against the same revenue is how a timing problem becomes a solvency problem. Work out what share of daily sales is already committed.
Frequently asked questions
How long does Walmart hold new seller payments?
Up to 14 days for US sellers and up to 21 days for non-US sellers, as a rolling delay. It ends only once 90 days have passed since your first shipped order and you have received $7,500 in payments. Payments can begin as soon as 30 days after your first sale.
Is payout acceleration cheaper than funding?
Not automatically. Payability's daily payout program carries daily fees for advancing sales. Because you would have received the money anyway, work out the annualised cost of pulling it forward and compare that against a funding fee for the same amount over the same period.
Which repayment structure survives a bad month?
A structure that takes a percentage of sales collects less when you sell less. Shopify Capital takes a fixed percentage of daily sales, only on days you sell. Onramp Funds' variable option repays as a share of sales. Fixed schedules and capped weekly payments do not shrink with revenue.
Can I use funding to pay suppliers directly?
Clearco's Invoice Funding covers vendor invoices upfront without using your cash reserves. Most other products on this page put cash in your account and leave the payment to you, which works but is a blunter instrument.
What does any of this cost?
None of these providers publishes a rate on its site. Onramp Funds publishes one transparent fee with no hidden costs, Fundbox publishes no early repayment fees, and Clearco allows early payment without penalty. For an actual comparison, ask each provider for the total amount repayable on a specific amount over a specific period, in writing.
