Running a B2B store on WooCommerce means your buyers often expect purchase orders, net payment terms, and formal invoices, not the same checkout flow used for consumer retail. WooCommerce gives merchants a flexible ecommerce foundation, but B2B invoicing usually needs extra configuration because invoice payment, net terms, buyer approval, PDF invoice delivery, payment reminders, and accounting sync are handled through plugins or integrations rather than one native workflow.
To automate B2B invoicing on WooCommerce, merchants need to connect checkout, invoice generation, payment terms, reminders, and receivables reconciliation into a repeatable process. That can start with a B2B invoice plugin and a PDF invoice tool, then expand into a full AR workflow with accounts receivable automation and net terms financing.
This guide covers how to automate B2B invoicing on WooCommerce in six steps: choosing the right plugin setup, enabling invoice payment at checkout, configuring terms, automating invoice delivery, syncing with accounting software, and using Resolve Pay to offer terms without creating a long cash flow gap. It also explains which parts WooCommerce can support with plugins and where a dedicated B2B payments platform creates a more scalable workflow.
WooCommerce was built as a flexible ecommerce platform, but most B2B invoice workflows require more than a standard cart and payment gateway. Wholesale buyers often need purchase orders, negotiated payment terms, tax documentation, invoice approvals, and a formal AR process before payment is complete.
B2B merchants usually run into these gaps when they try to manage invoicing directly inside WooCommerce:
The result is a fragmented process. Store teams may create invoices in WooCommerce, track terms in spreadsheets, send reminders manually, and reconcile payments separately in accounting software. That setup can work for a small number of accounts, but it becomes harder to manage as B2B order volume grows.
Before choosing tools, decide how much of the invoice-to-cash workflow you want to automate. Most WooCommerce merchants use one of three approaches.

AR automation platform |
Resolve Pay with WooCommerce integration |
B2B suppliers that want net terms, credit checks, invoicing, collections, and reconciliation in one workflow |

|
Accounting-led setup |
WooCommerce plus QuickBooks, Xero, Sage Intacct, NetSuite, or an ERP connector |
Businesses where finance systems are the source of record |
Usually handled outside WooCommerce |
Depends on internal collections process |
A plugin-only setup can be enough if you only need to show invoice payment at checkout and send PDFs. An accounting-led setup works when WooCommerce is mainly an order entry channel and your finance team already manages AR in an ERP.
Resolve Pay is designed for B2B merchants that want a more connected workflow. It combines net terms for ecommerce, buyer credit checks, invoice management, payment reminders, collections workflows, and integrations with finance systems. That matters when the goal is not just to generate invoices, but to offer terms without adding manual credit and collections work.
Before you start, make sure you have the following in place.
You need a WooCommerce store on WordPress and an admin account that can install plugins, configure payment methods, update checkout settings, and manage user roles.
Decide which customers should be allowed to pay by invoice. Most merchants limit invoice billing or net terms to approved wholesale accounts, company accounts, or specific B2B roles.
Decide whether you will offer Net 30, Net 60, Net 90, or custom terms. If terms vary by buyer, define those tiers before configuring your checkout and invoice rules.
Identify where invoices should ultimately live. Common destinations include QuickBooks, Xero, Sage Intacct, NetSuite, or another ERP. Strong recordkeeping helps businesses maintain clean financial data, and the IRS provides general guidance on keeping business records.
Net terms create a gap between shipment and payment. The U.S. Small Business Administration highlights cash flow management as a core part of business planning and operations through its cash flow guidance. Decide whether your business will fund that gap internally or use a platform like Resolve Pay.
WooCommerce does not provide a complete B2B invoicing stack by default. You need tools that match your workflow.
Invoice payment plugins can add a pay-by-invoice option at checkout and restrict that option by conditions such as user role, shipping method, product category, or location. This is useful when your main goal is to let approved buyers place orders without paying immediately.
Use this option when you need basic invoice payment access, but you already have a separate process for credit checks, reminders, and collections.
B2BKing is a broader B2B and wholesale plugin. It can support wholesale account management, customer groups, pricing rules, tax rules, and invoice payment workflows. For formal invoice PDFs, merchants commonly pair it with a dedicated PDF invoice plugin.
Use this option when you need B2B account controls and wholesale rules alongside invoice payment.
Wholesale Suite supports wholesale pricing and B2B customer management. Its payment-related modules can help merchants structure invoice-style payment options and reminders depending on the store setup.
Use this option when your store already runs on Wholesale Suite and you want invoicing to stay in that ecosystem.
PDF invoice tools are companion plugins, not full AR systems. The WordPress.org plugin for PDF invoices can automatically attach PDF invoices to WooCommerce emails, support sequential invoice numbers, and allow merchants to download or print invoice documents from the order admin.
Use this option with any invoice payment plugin so buyers receive formal invoice documentation.
Resolve Pay is not just a PDF invoice plugin. It is a B2B payments and receivables platform that supports net terms, buyer credit decisions, invoicing, collections, payment workflows, and finance stack integrations. Resolve Pay’s integrations product supports ecommerce and accounting workflows, including WooCommerce, QuickBooks Online, Xero, NetSuite, Sage Intacct, and custom API options.
Use Resolve Pay when you want to offer net terms through WooCommerce while also automating credit, collections, and reconciliation.
Once your plugin or platform is selected, the next step is to configure checkout so only approved B2B buyers see invoice payment or net terms.
In WooCommerce, go to WooCommerce > Settings > Payments and enable the invoice or net terms payment method provided by your selected plugin or platform. Then configure:
For Resolve Pay, the WooCommerce integration is designed to let business buyers apply for net terms at checkout and complete checkout when approved. Resolve Pay’s technical documentation notes that its WooCommerce plugin currently requires Classic Checkout rather than WooCommerce Checkout Blocks, so merchants should confirm checkout compatibility before implementation through the WooCommerce guide.
Invoice billing should not be visible to every visitor. Create a dedicated B2B role, such as “Wholesale Customer,” and only show invoice payment or net terms to accounts that meet your approval criteria.
A common rule structure looks like this:
This keeps invoice billing aligned with your credit policy.
Enabling invoice payment lets buyers place orders without immediate payment. Net terms define when payment is due and how your team manages the receivable.
Most B2B suppliers assign terms based on buyer type, relationship history, and risk profile. Common structures include:
If you manage terms manually, store them in buyer profiles and make sure each invoice displays the correct due date. If you use Resolve Pay, buyer terms and credit decisions can be managed as part of the broader business credit check and net terms workflow.
Each invoice should include:
Clear invoice data helps both buyer AP teams and seller finance teams process invoices more consistently.
Invoice automation is not complete when the PDF is generated. The workflow should also send the invoice, remind the buyer before and after the due date, and update the order or invoice status when payment arrives.
Configure your invoice plugin or AR platform to:
For regulated or formal invoice workflows, some merchants also need structured electronic invoice formats. The GSA provides an overview of electronic invoicing in federal procurement contexts, which can be a useful background for teams thinking about invoice standardization.
A simple reminder workflow can include:
Resolve Pay supports payment reminders and collections workflows as part of its receivables automation. This helps merchants reduce manual follow-up while keeping communications consistent and professional.
B2B collections should protect the buyer relationship. Use clear, direct language and include:
Avoid making your finance team rewrite reminder emails manually for every invoice.
A WooCommerce invoice only solves part of the problem if your accounting system does not stay current. Every invoice should appear in your financial records, and every payment should reconcile back to the right order or invoice.
WooCommerce merchants can use a connector or middleware to map orders into QuickBooks invoices, customers, and payments. If QuickBooks is your finance system, make sure the connector maps customer names, invoice numbers, tax details, payment status, and due dates correctly. For more context, see Resolve Pay’s guide to sync AR with QuickBooks.
Xero-based sellers can use WooCommerce integrations or middleware to create invoices from orders and keep payment status updated. If your team sells to B2B customers on terms, the due date in Xero should match the due date shown on the WooCommerce invoice.
Mid-market merchants often treat Sage Intacct or NetSuite as the system of record. In that setup, WooCommerce captures the order, but invoice records, payment status, and reconciliation need to land in the ERP. Resolve Pay supports connected workflows across ecommerce and ERP systems through ERP integrations, including Sage Intacct and NetSuite.
A reliable sync helps reduce:
Research and benchmarking organizations such as APQC track finance process performance, including invoice and receivables workflows. The practical takeaway for WooCommerce merchants is simple: the more your invoice data moves automatically, the less time your finance team spends re-keying and reconciling records.
This is the step many WooCommerce invoicing guides skip. If you offer Net 30, Net 60, or Net 90, your buyer gets time to pay, but your business still needs cash to cover inventory, suppliers, payroll, and operating expenses.
When you fund terms yourself, every unpaid invoice becomes working capital tied up in receivables. That can limit how many B2B orders you can accept, especially when larger buyers expect longer terms.
A small wholesale program may be manageable with internal cash. A growing B2B channel can create a much larger receivables balance, more credit decisions, and more follow-up work for your team.
Resolve Pay helps merchants offer terms while improving cash flow and reducing credit risk. Through net terms management, Resolve Pay can support buyer credit assessment, invoice workflows, payment reminders, collections, and payment reconciliation.
In a WooCommerce net terms workflow, Resolve Pay can support:
Resolve Pay’s model is non-recourse for approved advances, which means the merchant is not taking on the same credit exposure as a self-managed terms program. Buyer approvals, credit limits, and advance amounts remain subject to Resolve Pay verification and underwriting.
Resolve Pay can support:
This makes Resolve Pay a better fit for merchants that want to automate more than invoice PDFs. It connects the full credit-to-cash workflow.
Invoice payment and net terms should be limited to approved B2B buyers. Create user roles and approval workflows before exposing invoice payment at checkout.
PDF generation is useful, but it does not automate credit checks, reminders, collections, or reconciliation. Treat PDF invoices as one layer of a broader AR workflow.
If invoices stay in WooCommerce but payments are tracked somewhere else, your AR process will become harder to manage. Sync invoice and payment data to the finance system your team actually uses.
Net terms can help B2B buyers purchase more easily, but they also delay cash collection. Use internal working capital intentionally or add a platform like Resolve Pay to support upfront funding on approved invoices.
If you use Resolve Pay’s WooCommerce integration, confirm that your store uses Classic Checkout, since the current Resolve Pay WooCommerce documentation states that Checkout Blocks are not supported.
Create separate roles or groups for different payment policies, such as Net 30 wholesale, Net 60 wholesale, and prepaid wholesale. Then map checkout access and invoice terms to those groups.
Make payment easy for buyers by including a payment portal link in every invoice and reminder. Resolve Pay’s buyer portal supports multiple payment methods, which can reduce friction for AP teams.
Use a B2B registration form that collects company name, billing address, tax details, and purchase order requirements. Then route applicants through approval before granting invoice payment access. If you use Resolve Pay, buyer credit evaluation can be connected to the application and checkout workflow.
Make sure every invoice includes the fields buyer AP teams expect:
Standard fields reduce back-and-forth after orders are placed.
Sales teams should know whether key accounts are approved for terms, blocked due to overdue balances, or eligible for larger purchases. Resolve Pay’s AR and credit dashboards help centralize that visibility for teams managing B2B buyer relationships.
Automating B2B invoicing on WooCommerce requires more than installing one plugin. A complete setup connects checkout rules, invoice generation, buyer approval, net terms, payment reminders, accounting sync, and cash flow management into one workflow.
For smaller WooCommerce stores, a B2B invoice payment plugin plus a PDF invoice plugin can cover the basics. For stores with more complex buyer accounts, wholesale plugins can add group rules and account controls. For merchants that want to offer net terms without turning their finance team into a manual credit and collections department, Resolve Pay is the stronger long-term fit.
Resolve Pay helps B2B merchants offer terms, automate credit decisions, manage invoices and reminders, support buyer payments, and sync receivables data with finance systems. That makes it especially useful for WooCommerce stores that want to grow B2B sales while keeping cash flow and AR operations under control.
If your team is ready to offer net terms on WooCommerce with a more scalable receivables workflow, start with Resolve Pay.
WooCommerce supports ecommerce order management, but a complete B2B invoicing workflow usually requires plugins or integrations. Merchants typically add separate tools for invoice payment, PDF invoices, buyer approval, payment reminders, and accounting sync.
Yes, but not through the default WooCommerce setup alone. Merchants usually install a PDF invoice plugin, such as WooCommerce PDF Invoices & Packing Slips, to automatically attach invoice PDFs to order emails and generate sequential invoice numbers.
To add Net 30 terms, configure an invoice payment or net terms plugin, restrict it to approved B2B buyer roles, set the invoice due date, and make sure the invoice template displays the terms clearly. For a more automated workflow, Resolve Pay can support net terms at checkout, buyer credit checks, and receivables automation.
Resolve Pay helps merchants connect net terms, buyer credit decisions, invoicing, payment reminders, collections, and accounting sync into one workflow. It is designed for B2B merchants that want more than basic invoice generation.
If you manage invoice terms yourself, your team is responsible for follow-up and credit risk. With Resolve Pay, approved advances are non-recourse, and Resolve Pay supports payment reminders, collections workflows, and buyer payment management, subject to underwriting and program terms.
