What is the best online invoice factoring company for startups in 2026?
Factoring is one of the few financing options that judges your customer, not your company. For a startup with no credit history, that is the whole point.
You closed a customer who pays net 60. Payroll is due in two weeks. A bank wants two years of tax returns, and venture debt wants a priced round. Factoring is different: the factor buys or advances against an invoice, and what it really underwrites is the business that owes you the money.
The short answer: FundThrough is the best fit for most startups. It lists no minimum time in business or revenue, publishes a flat 1.9% to 2.9% per 30 days, and only needs outstanding invoices to a creditworthy customer. altLINE is the bank-backed alternative that openly works with startups, on recourse terms. If your customer might not pay at all, Riviera Finance offers non-recourse factoring.
We compared five factoring companies on what matters to a young company: whether they accept you, the cost of one $10,000 invoice paid at 45 days, recourse, volume minimums and the fees you only find in the contract.

The best invoice factoring for your stage
The 5 companies side by side
The price column shows the official rate where the company publishes one, or says when it only quotes. The rank follows what a US startup needs first: getting accepted without a track record. That is why Universal Funding, with the lowest headline rate, sits last: it wants $25,000 of invoices a month.

How we compared and scored
Most factoring rankings are written for established small businesses. A startup asks a different first question: will they take me? So access comes first in our weighting: minimum time in business, minimum revenue or monthly volume, credit checks, and the kind of customers accepted.
Cost comes second, converted to one $10,000 invoice paid at 45 days, because each company prices differently: per 30 days, by invoice age, or by quote. Then we look at recourse, contract terms and side fees (origination, ACH, wire, lockbox), the part most comparison pages skip. We read each company's own pricing and service pages. Scores match our small business factoring ranking, where the same companies appear: only the order changes, because the reader changes.

FundThrough
FundThrough is the factoring company we would show a founder first, for one reason: its pricing page lists no minimum time in business and no minimum revenue. What it needs is outstanding invoices to a customer that can pay. For a company that incorporated last year, that changes everything.
The fee is flat and published: 1.9% to 2.9% per 30 days for businesses with up to $999,999 of outstanding invoices, with a custom quote above that. The application takes under five minutes. On a $10,000 invoice paid within 30 days, you pay $190 to $290. Paid at day 45, a second 30-day period starts, so the same invoice costs $380 to $580.
What it does better: clarity and speed for a first-time user. You know the range before you apply, and where you land in it depends on your and your customer's eligibility.
Its limit: invoices must be B2B or government, for completed work, and both you and your customer must be in the US or Canada. Construction and real estate are excluded. If you bill in advance for work not yet delivered, such as an annual software subscription, it is not a fit.
Tip: because the fee runs per 30-day period, factor the invoices of customers who pay on time, and avoid the ones who usually pay on day 32. One day late doubles your cost on that invoice.
- No minimum time in business listed
- Flat fee per 30 days
- Government invoices accepted
- ✓Pricing published before you apply
- ✓Application in under five minutes
- ✓Works with one customer
- ✗Second fee period if paid late
- ✗Completed work only
- ✗US and Canada only
The easiest door for a startup with a good customer and no history. Watch the 30-day periods: they decide your real cost.
altLINE
altLINE is run with The Southern Bank Company, and it has a page that says plainly how it treats startups. There is no credit score threshold, but there is a background check, and startups get recourse factoring only: if your customer fails to pay, the invoice comes back to you.
It advances 80% to 90% of the invoice, and funds usually arrive within 24 to 48 hours. Its rates start at 0.50% and typically run from 1% to 5%, rising as the invoice ages. On its own illustrative schedule, 1.5% covers the first 30 days and 2.5% applies from day 41 to day 50, so our $10,000 invoice at day 45 costs about $250. That is cheaper than FundThrough on a 45-day invoice.
What it does better: it lists the extras. Origination is $150 to $500, charged once you are funded, and wires cost $15 to $30. Even so, user reviews note ACH and wire fees despite a "no hidden fees" message, so ask for the full schedule in writing.
Its limit: the 10% to 20% held back arrives only when your customer pays, and the rate climbs every ten days past the first month. Its own rates guide describes automatic renewal with a 30-day window to leave, so check that clause in your contract.
Tip: if your runway is tight, ask altLINE which advance rate it would give on your specific customer. On a large, well-rated customer, the 90% end matters more than the headline rate.
- Openly accepts startups
- Bank-backed
- Funds in 24 to 48 hours
- ✓No credit score threshold
- ✓Fee schedule published
- ✓Cheaper than flat fees on 45-day invoices
- ✗Recourse only for startups
- ✗Advance capped at 90%
- ✗Check the renewal clause
A solid, transparent choice once you accept recourse. Put the renewal date in your calendar the day you sign.
Riviera Finance
Riviera Finance offers non-recourse factoring: if your customer becomes insolvent after Riviera buys the invoice, Riviera takes the loss. For a startup, that is a real difference. Many early customers are other young companies, and one of them going under can wipe out a quarter of your revenue.
It advances up to 95% of the invoice, more than altLINE. Its fee is a percentage of each invoice, fixed in advance, but it is not published: you get it with a quote. That makes it impossible to compare before you talk to them, so plan a call early rather than the week payroll is due.
What it does better: credit checks on your customers. Riviera vets and guarantees the credit of the businesses you invoice, which works like bad-debt insurance on those invoices. For a startup without a finance team, that check is worth something on its own.
Its limit: no public rate, so every fee comes with the quote. And the page covers a customer who cannot pay, not one who disputes your work: if your customer refuses to pay because a feature was late, ask in writing whether that risk stays yours.
Tip: ask Riviera to run a credit check on a prospect before you sign the deal. If it will not cover that customer, you have learned something about the deal itself.
- Non-recourse
- Up to 95% advanced
- Customer credit checks included
- ✓Protects against customer insolvency
- ✓High advance rate
- ✓Useful credit insight on prospects
- ✗Rates not published
- ✗Fees only on a quote
- ✗Disputes usually not covered
The pick when the risk is your customer, not your cash flow. Get every fee in writing before you sign.
eCapital
eCapital is a large factoring company with products for many industries. It does not publish a rate card, but its own explanation of factoring gives the range: fees typically between 1% and 5% or more of the invoice, driven mostly by your customers' creditworthiness. That logic suits a startup: your customer's credit weighs more than your own.
On a $10,000 invoice, expect $100 to $500 or more. It can advance up to 100% depending on terms and usually funds within 24 to 48 hours after approval.
What it does better: speed. Funds usually arrive within 24 to 48 hours of approval, and the quote is free and carries no obligation.
Its limit: the range is wide, and contract length, minimum volume and reserves are not on the page. Your customers are usually told to pay eCapital directly, which some early customers may question.
Tip: convert any eCapital quote to the cost of the same invoice over 30 and 45 days, and compare it with FundThrough. A low rate with a reserve and a volume minimum can end up costing more than a flat fee.
- Funding in 24 to 48 hours
- Up to 100% advanced
- Many industries served
- ✓Pricing driven by your customers' credit
- ✓Fast decisions
- ✓Free quote
- ✗Wide fee range
- ✗Contract terms not published
- ✗Customers pay eCapital directly
Worth a quote when speed matters most. Insist on the contract terms before you commit.
Universal Funding
Universal Funding publishes the lowest headline rate in this ranking: from 0.55%, and generally no higher than 2%, for the first 30 days. It advances up to 95% of eligible invoices. On a $10,000 invoice paid within 30 days, that is $55 to $200.
It is also one of the few to list its side fees: $35 for credit approvals, $50 for the lockbox and $30 per outgoing wire, with no monthly access fee.
Why only fifth for startups: the eligible monthly invoice volume starts at $25,000. A company with one $10,000 invoice a month does not qualify. Recourse terms and contract length are not on its rates page either.
Tip: once your monthly invoicing passes $25,000, get a Universal Funding quote and compare it with your current factor. The gap on a full month of invoices can pay for the switch.
- Lowest published rate
- Side fees listed
- Up to 95% advanced
- ✓Very low rate for 30 days
- ✓No monthly access fee
- ✓Transparent extras
- ✗$25,000 monthly volume to start
- ✗Recourse terms not published
- ✗Contract length not published
A company to switch to once your volume grows, not the first door for a young startup.
What other guides leave out
Most pages on factoring for startups list companies and quote a rate range. Few price the same invoice everywhere, and almost none explain why a factor can say yes to you when a bank says no.
Why a factor accepts you when a bank will not
A lender judges your company: credit history, revenue, time in business. A factor mostly judges the customer who owes you money. That is why altLINE has no credit score threshold and FundThrough lists no minimum time in business. Your best asset is not your balance sheet, it is a signed invoice to a solid business. A factor still wants invoices, though: if you have not billed anyone yet, factoring cannot help.
What a $10,000 invoice really costs at 45 days
At FundThrough, $380 to $580, because day 45 falls in a second 30-day period. At altLINE, about $250 on its illustrative schedule, plus origination once. At Universal Funding, $55 to $200 for 30 days, then more, if you reach its $25,000 monthly minimum. At Riviera Finance and eCapital, only a quote will tell. The lesson: the rate matters less than how it runs over time and when your customer actually pays.
Recourse when your customers are startups too
Startups often sell to other startups. With recourse, which altLINE requires of young companies, an unpaid invoice comes back to you, with the advance to repay. If your main customer is fragile, non-recourse at Riviera Finance costs more but protects your runway. Remember that non-recourse usually covers insolvency, not a dispute.
- Check that your invoices are B2B or government, for work already delivered.
- Ask for the full fee schedule: origination, ACH, wire, lockbox.
- Price the same invoice at 30 and 45 days with each company.
- Ask whether your contract is recourse or non-recourse.
- Note the renewal date and the notice window.
- Keep a second source of cash ready.
When factoring is not the right tool
Factoring answers one question: getting paid earlier on invoices you have already sent. Here are three common startup situations where something else fits better.
Fundbox: a line of credit rather than factoring
Credit lineFundbox offers credit to small businesses, with loans made by First Electronic Bank or Lead Bank. Its pricing page no longer shows any figure, so you only see your cost once you apply. A line of credit suits a startup that needs flexibility, not an advance on one invoice. Compare the total cost to factoring before you draw.
- Published pricing
- None on its pricing page
Capchase: financing for software companies with recurring revenue
SaaSIf you sell annual software subscriptions billed monthly, factoring each invoice makes little sense. Capchase advances future recurring revenue instead. It publishes no pricing, so ask for the total cost over the full term and compare it with what the same cash would cost in a round.
- Published pricing
- None
Prepaid annual contracts: ask your customer first
FreeBefore paying a factor, ask your customer to pay annually upfront, against a small discount. A 2% discount on an annual contract often costs less than factoring the same amount at FundThrough for two 30-day periods. Make the offer in your proposal, before the contract is signed, not after.
- Cost
- The discount you choose

Invoice factoring for startups · FAQ
Can a startup with no credit history factor its invoices?
Yes, because a factor mostly underwrites your customer, not you. altLINE has no credit score threshold for startups, and FundThrough lists no minimum time in business. What you do need is an invoice for completed work to a creditworthy business or government customer.How much does invoice factoring cost a startup?
On a $10,000 invoice paid at 45 days: $380 to $580 at FundThrough, about $250 at altLINE on its illustrative schedule, and a quote at Riviera Finance or eCapital. Add origination and transfer fees, and always compare the cost over the real payment delay, not the first 30 days.Should a startup choose recourse or non-recourse factoring?
Recourse is cheaper and often the only option for a young company: altLINE offers startups recourse only. Choose non-recourse, such as Riviera Finance, when your main customer is itself fragile. It covers insolvency, usually not a dispute over your work.What hidden fees should a startup watch for?
Origination ($150 to $500 at altLINE), wires ($15 to $30 at altLINE, $30 at Universal Funding), lockbox and credit approval fees, monthly volume minimums and automatic renewals. Ask for the complete schedule in writing before you sign, even when the website says there are no hidden fees.Can a SaaS company factor annual contracts?
Only invoices for work already delivered. FundThrough requires completed work, so an annual subscription billed in advance usually does not qualify. Recurring revenue financing such as Capchase, or asking your customer to prepay against a discount, fits better.Is factoring better than a line of credit for a startup?
Factoring is easier to get without history, because it relies on your customer. A line of credit, like Fundbox, is more flexible but judges your own business and does not publish its pricing. Many startups use factoring first and add a credit line once they have a track record.Will my customer know I am factoring their invoice?
Usually yes. In most factoring contracts, your customer is told to pay the factor directly, as at eCapital. Warn your customer yourself and present it as a payment detail. With a strategic first customer, consider a solution that keeps the relationship in your hands.
