Resolve Pay vs Slope vs FundThrough: 2026 Comparison

B2B suppliers comparing Resolve Pay, Slope, and FundThrough are usually trying to solve one core problem: how to offer buyers more flexibility without putting extra pressure on cash flow. That question matters more when payment cycles stretch across 30, 60, or 90 days and finance teams still need to fund payroll, inventory, and operations on schedule. The SBA notes that net terms can help conserve business cash flow, while the Federal Reserve continues to highlight how access to business credit shapes growth options for small firms. At the same time, embedded finance keeps expanding as a B2B infrastructure layer, with Bain projecting transaction value to reach $7 trillion in 2026.

That is why this comparison is practical, not theoretical. Resolve Pay is built for merchants, manufacturers, wholesalers, and distributors that want to offer net terms, get paid faster, and automate receivables workflows in one place. Slope is an API-first B2B payments platform used in embedded and marketplace environments. FundThrough is an invoice factoring platform focused on turning eligible invoices into faster cash. These products overlap around cash flow, but they address different workflows, operating models, and risk structures. For businesses that want a platform centered on trade credit, receivables automation, and supplier cash flow, Resolve Pay is the clearest fit.

Key takeaways

• Resolve Pay is built around net terms workflows: It combines buyer underwriting, receivables automation, invoicing, collections, and payments for B2B sellers that want to extend terms without adding manual overhead.
• Resolve Pay reduces supplier risk exposure: Its non-recourse model is designed to help suppliers offer terms while protecting cash flow on approved invoices.
• Slope is primarily an embedded payments infrastructure play: It is best understood as a platform for API-led checkout, financing, and payment experiences inside larger commerce environments.
• FundThrough is focused on invoice factoring: It helps businesses accelerate cash from existing invoices rather than managing the full net terms lifecycle from approval through repayment.
• The operating model matters as much as funding speed: Suppliers choosing between these platforms are really choosing between a net terms platform, an embedded payments layer, and a factoring workflow.
• Resolve Pay is the strongest fit for B2B sellers that want one system for credit and AR: It is especially relevant for teams that want buyer approvals, payments, reconciliation, and collections connected in a single workflow.

Why B2B suppliers compare Resolve Pay vs Slope vs FundThrough

Teams evaluating these platforms are often dealing with the same underlying pressure: sales wants to offer terms, buyers expect flexibility, and finance wants to avoid stretching working capital or adding more collections work. Net terms can help preserve cash for buyers, but they also create more credit and receivables complexity for suppliers when managed manually. Resolve Pay is built around that problem by combining credit, invoicing, collections, and payments in one platform.

The second driver is embedded finance. Bain projects embedded finance transaction value to reach $7 trillion in 2026, which helps explain why platforms like Slope are being deployed inside larger digital commerce experiences. At the same time, businesses that already issue invoices often look at factoring options such as FundThrough when they want to pull cash forward from receivables they have already created.

The result is that these three platforms can appear similar from a distance while solving different operational jobs.

Quick overview

Resolve Pay

Resolve Pay is a B2B payments and net terms platform for sellers that want to offer terms while improving cash flow and reducing credit risk. Its product set spans net terms, accounts receivable automation, business credit checks, and integrations across ecommerce, ERP, and accounting systems. Resolve Pay states that it has served more than 15,000 businesses and won BigCommerce’s 2025 Innovative Integration Award.

What makes Resolve Pay stand out in this comparison is that it is not just a funding tool. It is designed to support the full credit-to-cash workflow, including buyer approvals, invoicing, payment tracking, reconciliation, collections, and a branded payment experience. For suppliers that want to offer terms without running a patchwork of separate credit, AR, and payment tools, that positioning is important.

Slope

Slope is a B2B payments platform centered on embedded payments and financing. Its positioning is API-first, with checkout and financing experiences built into broader commerce or marketplace flows. Slope’s own materials describe deployments on platforms such as Walmart, Alibaba, IKEA, and Samsung, which makes it most relevant for businesses that need infrastructure embedded inside an existing buying experience rather than a supplier-first AR workflow.

FundThrough

FundThrough is an invoice factoring provider that helps businesses get paid faster on eligible invoices. Its workflow is oriented around existing receivables rather than point-of-sale or checkout financing. FundThrough supports integrations with QuickBooks, OpenInvoice, and Xero, and it markets funding on invoices from businesses in the U.S. and Canada.

Core differences in product model

Resolve Pay: net terms plus receivables automation

Resolve Pay is best viewed as a platform for businesses that want to extend trade credit in a controlled way. It underwrites buyers, supports net terms, advances payment on approved invoices, and automates much of the receivables workflow. Resolve Pay also supports a buyer portal, a seller workflow, and a better-than-factoring positioning for suppliers that want to improve cash flow without relying on a traditional factoring model.

Slope: embedded B2B payments infrastructure

Slope is more infrastructure-oriented. Its role is to power financing and payment experiences inside platforms and checkout flows. That makes it a different operational fit from Resolve Pay. A marketplace operator or platform team looking for embedded credit and payments may find Slope aligned with that use case, while a wholesaler or manufacturer looking for day-to-day receivables automation is usually solving a different problem.

FundThrough: factoring against existing invoices

FundThrough is focused on accelerating cash from invoices that already exist. The business uploads or syncs eligible invoices and selects which ones to fund. That model can be useful when the priority is unlocking working capital from receivables without changing how terms are offered at checkout or during account setup.

Feature comparison

How the risk model differs

Resolve Pay centers risk protection for suppliers

Resolve Pay’s non-recourse positioning is a major difference in this comparison. Resolve states that its cash advances are non-recourse and that it manages credit approval, underwriting, and collections for approved transactions. For suppliers that want to offer terms while keeping credit exposure off their own books, that is one of the strongest reasons to choose Resolve Pay.

Slope’s risk model is tied to embedded program structure

Slope’s model is more program-specific because it operates inside embedded and marketplace environments. In practice, that means the risk setup depends on how the platform is deployed and how the financing program is structured. That is useful to know because it differs from the more supplier-centered positioning Resolve Pay uses in its net terms workflow.

FundThrough is built around factoring dynamics

FundThrough’s model is tied to factoring rather than non-recourse net terms management. Businesses are using existing invoices to access earlier payment, which is operationally different from extending net terms through a platform that also manages buyer underwriting and AR workflows from the start of the transaction.

Integrations and operational workflow

Resolve Pay has the deepest fit for teams that want operational workflow support across more than one system. Its integration stack includes QuickBooks Online, Xero, NetSuite, Sage Intacct, Magento, Shopify, BigCommerce, and WooCommerce, and its accounts receivable platform is built to automate invoicing, reconciliation, payment reminders, and collections. That makes Resolve Pay especially relevant for businesses trying to replace spreadsheet-heavy AR work with one connected process.

Slope’s workflow is more centered on API deployment and embedded payment logic. For businesses building financing into a platform or checkout experience, that can be the right architecture. FundThrough, by contrast, is most straightforward for teams that want invoice sync through QuickBooks, OpenInvoice, or Xero and prefer a factoring workflow over a broader receivables platform.

Which platform fits which business

Choose Resolve Pay if you want to offer terms and automate AR

Resolve Pay is the strongest fit for businesses that want to grow B2B sales by offering terms while also reducing manual receivables work. It is especially well suited to suppliers that want:

• Net terms management
• Business credit checks
• AR automation
• B2B payments workflows
• Connected ERP and ecommerce data flows through integrations

This is the clearest choice for merchants, manufacturers, wholesalers, and distributors that want one system to support buyer approvals, invoicing, payments, reconciliation, and collections.

Choose Slope if you are embedding financing into a platform

Slope is the better fit when the job is to power embedded payments and financing inside a marketplace, software platform, or checkout environment. Its operating model is more infrastructure-led than supplier-led.

Choose FundThrough if you want to fund existing invoices

FundThrough is the right comparison point when the business is not looking to redesign how it offers terms, but instead wants to pull forward cash from receivables that are already outstanding. Its first-funding eligibility materials also note a threshold around $100,000 in receivables to one customer or a first funding amount below that level being ineligible, which matters for smaller businesses evaluating fit.

Final verdict

For businesses evaluating Resolve Pay vs Slope vs FundThrough, the best choice depends on what part of the workflow needs to change. If the goal is embedded financing inside a marketplace or platform, Slope is the relevant model. If the goal is accelerating cash from invoices that already exist, FundThrough is the relevant model.

But for B2B sellers that want to offer terms, get paid faster, reduce credit exposure, and automate receivables in one place, Resolve Pay is the strongest overall fit. Its combination of non-recourse positioning, buyer underwriting, AR automation, payment workflows, and broad integrations makes it the most complete platform in this comparison for supplier-led B2B commerce. Businesses that want a more modern alternative to manual trade credit management or traditional factoring should start with Resolve Pay.
