FundThrough business loan review: Interest rates, eligibility, and the application process

Waiting 30, 60, or even 90 days to get paid can stall momentum for any growing business. Payroll still runs weekly, suppliers expect payment, and opportunities rarely wait for invoices to clear.

That’s where FundThrough comes in. Instead of taking on new debt, the platform lets B2B companies unlock cash already tied up in unpaid invoices, often within a single business day. It’s not a loan; it’s an advance on revenue you’ve already earned. For founders focused on cash flow and flexibility, that distinction matters.

This review explores how FundThrough works, what it costs, who it’s right for, and how it compares to other funding routes available through Swoop Funding.

An overview of FundThrough business loans

FundThrough isn’t a traditional lender. It’s an invoice-funding platform that gives U.S. and Canadian businesses quick access to cash by advancing payment on approved invoices. You upload or sync invoices, receive up to 100% of their value (minus a small fee), and your customer later pays FundThrough directly under the original terms.

There’s no lump-sum loan, fixed repayment schedule, or long-term contract. You decide which invoices to fund and when, a flexible option for smoothing cash flow without taking on new liabilities.

Unsecured business loans

FundThrough doesn’t issue unsecured term loans. Instead, approval is based on:

Invoice value: The amount owed by your customer.
Customer credit quality: Whether your clients have strong payment histories.
Invoice age: Invoices must be less than 90 days old.

Because the invoices themselves secure the advance, companies that may not qualify for unsecured bank credit can still access funding through FundThrough.

Secured business loans

Invoice funding is technically a form of secured finance, but the security is limited to each funded invoice, not your property or business assets. FundThrough advances cash against completed work that’s already invoiced, then collects directly from your customer when payment is due.

This structure contains risk to the transaction itself, protecting your broader balance sheet.

Growth Guarantee Scheme

FundThrough is privately operated and does not participate in government-backed lending programs such as the SBA or Growth Guarantee Scheme. Businesses seeking subsidized interest rates or longer repayment terms may prefer exploring SBA loans or other bank loan options.

Additional funding products

FundThrough focuses exclusively on invoice funding. There are no merchant cash advances, term loans, or revolving credit lines offered alongside it, and that’s deliberate. Its entire platform is built for B2B companies and agencies that invoice other businesses or government entities and need faster, predictable access to working capital.

What is FundThrough’s typical interest rate?

FundThrough doesn’t charge interest or quote APRs. Instead, it applies a flat transaction fee based on how long an invoice remains unpaid.

Typical cost structure:

Fee range: 2.2% to 3% per 30 days outstanding
Larger volumes: May qualify for custom rates
Interest: None (no compounding)

Because cost is time-based, faster-paying customers reduce total expense. For short payment cycles, this model can be more predictable than a traditional loan, even if the headline percentage appears higher.

How much can I borrow with a FundThrough business loan?

There’s no fixed borrowing limit because advances are tied to your invoice total rather than a preset credit line. FundThrough can advance up to 100% of the eligible invoice value, minus the applicable fee.

Your available capital depends on:

Total approved invoices: The cumulative value of invoices selected.
Customer creditworthiness: How reliably your clients pay.
Invoice age: Invoices older than 90 days aren’t eligible.

As your sales grow, your available funding increases naturally.

What is the acceptance rate for a FundThrough business loan?

FundThrough doesn’t publish acceptance rates, but approval depends far more on your customers’ credit strength than on your own financials. Businesses with established, creditworthy B2B clients often find invoice funding more accessible than loans based on balance-sheet or credit-score requirements.

Eligibility criteria and whether you qualify

You may qualify for FundThrough financing if you:

Operate in the U.S. or Canada
Invoice other businesses or government agencies for completed work
Have invoices under 90 days old
Have no conflicting liens on receivables

FundThrough is not available for:

B2C companies
Construction or real-estate businesses
Invoices tied to uncompleted or disputed work

Additional information

Early repayment fees

There are no prepayment penalties. Because fees are time-based, faster invoice settlement automatically lowers cost.

How long does it take to get approved?

Setup takes minutes, especially if you connect accounting software like QuickBooks Online or OpenInvoice. Once verified, invoices can be approved within days.

Estimated time to receive funds

After invoice approval, funds are typically deposited as soon as the next business day.

Can a loan be repaid early?

There’s no loan to repay. Once your customer pays FundThrough under the original invoice terms, the transaction closes automatically.

Is security required?

No additional collateral beyond the funded invoice is needed. FundThrough does not file blanket liens or require personal guarantees.

What documentation is required

Compared to a traditional loan, documentation is light.

Business information

Business name and address: For verification.
Industry: To assess eligibility.
Accounting connection: Sync via QuickBooks Online, Xero, or upload invoices manually.

Business owner information

Owner identification: To comply with AML/KYC rules.
Contact details: Email and phone number for updates.

Funding requirement

Invoices to fund: Upload or sync selected invoices.
Customer details: For payment verification.
Completion confirmation: Proof that work has been performed.

How to apply for a FundThrough business loan

The process is straightforward and entirely online:

Step 1 – Create an account or connect accounting software:
Set up a free FundThrough account, then sync QuickBooks Online or OpenInvoice. Xero users can import invoices manually after sign-up.
Step 2 – Select invoices to fund:
Choose which invoices you want to advance; there’s no requirement to fund all receivables. Invoices must be for completed work, under 90 days old, and issued to B2B or government clients.
Step 3 – Invoice verification:
FundThrough verifies each invoice and notifies your customer professionally before redirecting payment. Clients continue to pay under the original net terms.
Step 4 – Receive funds:
Once approved, you receive up to 100% of invoice value (minus fees), typically by the next business day.
Step 5 – Settlement:
When your customer pays FundThrough, the transaction closes. You can repeat the process anytime as new invoices are issued.

Is the application process different from other lenders?

Yes. FundThrough’s approval is based on completed work and client reliability, not projections or credit scores. There’s no lengthy underwriting or personal-credit scrutiny, and setup can take minutes instead of weeks.

How to improve your chances of getting funded

Keep invoices under 90 days old.
Work with creditworthy customers.
Resolve any existing liens on receivables.
Know your payment timelines to estimate the total cost accurately.
Verify details in accounting software before syncing.

Pros & cons of a FundThrough business loan

Invoice funding solves a timing problem, not a lifetime financing need. FundThrough turns approved receivables into cash fast and keeps the obligation tied to each invoice, which can be a clean way to smooth cash flow. The trade-off: costs rise the longer customers take to pay, and it’s not designed for long-term growth capital. Here are some additional pros and cons to consider:

Pros

Fast funding: Cash available as soon as the next business day.
No long-term debt: You’re advancing earned revenue, not borrowing.
High advance rates: Up to 100% of invoice value.
Transparent pricing: Flat monthly fees (2.2% to 3% per 30 days).
Flexible use: Choose which invoices to fund and when.

Cons

Cost depends on customer payment speed: Longer payment cycles raise total fees.
Industry restrictions: Not available for construction, real estate, or B2C.
Customer notification required: Clients pay FundThrough directly.
Short-term tool: Best for managing cash flow, not long-term growth financing.

Alternative funding options for different lenders

Depending on your goals, you might compare FundThrough with:

SBA loans: Longer-term, lower-cost financing for expansion.
Business lines of credit: Reusable access to capital for recurring needs.
Term loans: Structured, fixed-payment financing for equipment or growth.
Other invoice-finance platforms: Fee structures and advance rates vary.

Evaluating these side-by-side helps determine which model fits your business cash-flow rhythm best.
