Automate B2B Invoicing on Shopify: Step-by-Step 2026 Guide

Written by Resolve Team | Apr 30, 2026 10:06:40 AM

 

B2B invoicing on Shopify becomes harder to manage as soon as buyers expect payment terms, purchase order references, formal invoices, and account-level controls. Shopify can now support many core B2B workflows through company accounts, company locations, catalogs, PO numbers, net terms, ACH payments, and payment reminders, but merchants still need a structured receivables process around those features. The goal is not just to send invoices faster. It is to connect buyer approval, invoice delivery, payment follow-up, and reconciliation into one workflow that finance teams can trust.

For many B2B merchants, the biggest challenge is the gap between order volume and cash timing. Every approved buyer on net terms creates an invoice that may not be paid for 30, 60, or 90 days. Without automation, teams spend time generating PDFs, chasing AP contacts, checking bank deposits, and updating accounting records manually.

This guide shows how to automate B2B invoicing on Shopify step by step, from company account setup to invoice generation, payment reminders, reconciliation, and cash flow support. It also explains where Resolve Pay fits as a B2B payments and accounts receivable automation layer for merchants that want automated credit decisions, net terms workflows, non-recourse advance pay, and cleaner receivables operations.

Key Takeaways

  • Shopify can support B2B invoicing foundations: Company accounts, company locations, PO numbers, net terms, ACH payments, and payment reminders help merchants structure B2B checkout and billing workflows.
  • Invoice automation still matters: Shopify order notifications are not always enough for B2B accounts payable teams, so merchants often need formal invoice generation and delivery workflows.
  • Net terms require credit controls: Offering net 30, net 60, or net 90 creates credit exposure, which makes buyer assessment and credit limits important before terms are activated.
  • Payment reminders need structure: A simple reminder can help, but growing B2B teams usually need staged follow-ups before, on, and after the invoice due date.
  • Reconciliation closes the workflow loop: Automated payment matching helps keep open invoices, cash receipts, and accounting records aligned without manual spreadsheet checks.
  • Resolve Pay adds the cash flow layer: Resolve Pay helps merchants offer net terms, automate AR workflows, receive advance pay on approved invoices, and reduce credit risk through a non-recourse model.

Why Manual B2B Invoicing on Shopify Breaks at Scale

The core problem is not that Shopify cannot support B2B invoicing. It is that B2B invoicing includes more steps than a typical D2C checkout flow: buyer account setup, payment terms, purchase order capture, formal invoice delivery, payment reminders, credit controls, and reconciliation.

At low volume, draft orders and manually exported PDFs can work. As B2B order volume grows, data entry errors, missed follow-ups, and unmatched payments become harder to manage. A buyer may place an order through Shopify, receive goods, pay later by ACH or check, and expect the invoice to match their internal PO and AP workflow. If those steps are handled manually, the process becomes fragile.

Manual B2B invoicing usually creates four problems:

  • Delayed invoice delivery: Finance teams generate or send invoices after the order instead of having them triggered automatically.
  • Inconsistent follow-up: Payment reminders depend on calendar checks, spreadsheets, or one-off emails.
  • Credit exposure: Buyers may receive terms before their creditworthiness is properly reviewed.
  • Reconciliation gaps: Incoming ACH, wire, check, or card payments need to be matched back to open invoices and accounting records.

Late payments are also a real operating risk for small businesses. A recent QuickBooks report found that many small businesses continue to deal with overdue invoices, which makes receivables discipline especially important for B2B merchants extending terms.

The scale of Shopify B2B growth makes this workflow more important. Shopify’s own B2B plan documentation now lists B2B features across Basic, Grow, Advanced, and Plus plans, including companies, company locations, net terms, ACH payments, payment reminders, draft order to invoice, PO numbers, and Shopify Flow support. That broader access gives more merchants a foundation for B2B invoicing, but it does not remove the need for credit management, AR automation, and reconciliation discipline.

What You Need to Automate B2B Invoicing on Shopify

Before you automate B2B invoicing on Shopify, confirm that you have the following pieces in place.

A Shopify store with B2B features enabled

Shopify’s current B2B features by plan include companies, company locations, net terms, ACH payments, payment reminders, draft order to invoice, PO numbers, and Shopify Flow support across paid plans. Some advanced B2B capabilities remain plan-specific, so merchants should confirm their exact plan limits before building the workflow.

B2B buyers identified

You need a clear list of buyers who should receive invoice-based payment options instead of paying at checkout. These are usually wholesale accounts, distributors, retailers, institutional buyers, or repeat business customers.

A formal invoice workflow

B2B buyers often need invoices with invoice numbers, due dates, PO references, itemized line items, tax information, and payment instructions. Shopify’s checkout and notification tools can support parts of the flow, but many merchants still use a dedicated invoice workflow to standardize the PDF and delivery process.

A credit decision process

Every buyer on net terms represents a credit decision. Before offering net 30, net 60, or net 90, merchants should define how they review buyer risk, assign credit limits, and monitor payment behavior. Resolve Pay’s business credit check can support this process by helping merchants evaluate buyers before extending terms.

An accounting or ERP system

Your Shopify invoicing workflow should connect to the system where finance manages the ledger, whether that is QuickBooks, Xero, NetSuite, Sage Intacct, or another ERP. Resolve Pay’s integrations are designed to connect ecommerce, accounting, and ERP workflows so receivables data does not have to be re-entered manually.

Step 1: Set Up B2B Company Accounts in Shopify

Shopify company accounts are the foundation for B2B invoicing automation. They group individual buyer contacts under a business account, support account-specific purchasing workflows, and provide the structure needed for company locations, PO numbers, catalogs, and payment terms.

How to create a company account

  • In your Shopify admin, go to Customers → Companies.
  • Click Add company.
  • Enter the company name and link one or more customer contacts.
  • Assign a catalog if the buyer should see account-specific products or pricing.
  • Add one or more company locations for separate billing or shipping workflows.

Why company locations matter

Shopify’s payment terms documentation states that payment terms can be set for each company location. This matters because one buyer may have multiple purchasing entities, regional warehouses, or billing contacts. Assigning terms at the location level gives finance teams more control over how credit policies apply across the same parent account.

Once company accounts are configured, B2B buyers can log in, see their assigned purchasing experience, reference PO numbers where applicable, and move through a checkout flow that better reflects how business purchasing works.

Step 2: Assign Net Terms to Approved Buyers

With company accounts in place, you can assign net payment terms to approved company locations. Net terms define how long the buyer has to pay after an order or invoice is created. Shopify supports payment terms for B2B orders, and buyers can view the assigned terms when they place orders through the online store.

For merchants building a broader net terms program, Resolve Pay’s B2B net terms platform can add automated buyer credit decisions, advance pay on approved invoices, and non-recourse protection so sellers do not have to manage every credit and collection workflow in-house.

How to assign payment terms

  • Open the company account.
  • Select the relevant company location.
  • Go to the payment terms settings.
  • Choose the appropriate terms for that buyer location.
  • Review whether the buyer also needs a credit limit or internal approval workflow.

Before you assign terms

Extending net terms is similar to extending trade credit. At minimum, merchants should verify that a new buyer is a real business, review trade references or payment history where available, and set an appropriate credit limit.

For merchants that want to offer terms without carrying all of the credit and collections work themselves, Resolve Pay can act as a credit, payments, and receivables layer. Resolve Pay helps sellers offer terms while managing credit assessment, payment workflows, collections, and advance pay on approved invoices.

Step 3: Automate Invoice Generation and Delivery

This is where many Shopify B2B invoicing workflows break down. A Shopify order confirmation is not always the same thing as the formal invoice a buyer’s AP team expects. B2B invoices often need to include:

  • Sequential invoice number
  • Invoice date and due date
  • PO number
  • Itemized products, quantities, tax, and totals
  • Billing and shipping details
  • Payment instructions
  • Supplier details

A dedicated invoice automation workflow helps standardize those fields and send the invoice automatically after the right order event.

Common invoice automation options

Some Shopify merchants use invoice apps to generate PDF invoices and send them to buyers automatically. These tools can be useful for merchants that primarily need invoice formatting and delivery. Keep the selection neutral and practical: choose the tool that matches your market, tax requirements, accounting stack, and order volume.

What to configure

When setting up invoice automation, focus on the workflow rather than the tool name:

  1. Connect the invoice workflow to Shopify order data.
  2. Configure the invoice template with your logo, payment instructions, tax settings, and required footer language.
  3. Confirm that PO numbers and company billing details appear correctly.
  4. Choose the invoice trigger, such as order creation, payment terms assignment, fulfillment, or another internal event.
  5. Set the recipient as the company billing contact or a dedicated AP email.
  6. Test the workflow with a sample B2B order before going live.

From this point, every new order from a B2B company account can trigger an invoice workflow without manual copy-pasting or PDF creation.

Step 4: Build a Multi-Step Payment Reminder Sequence

Invoice delivery does not guarantee on-time payment. The next step is a structured reminder sequence that runs before, on, and after the invoice due date. Shopify includes B2B payment reminder support in its plan feature documentation, and Shopify Flow also includes a payment reminder action that can send reminders based on a payment schedule.

For merchants that need more advanced workflows, Resolve Pay’s accounts receivable platform can help automate payment reminders, collections workflows, and invoice reconciliation across receivables.

A defined sequence keeps the process consistent. It also helps avoid the common pattern where finance teams follow up aggressively on some invoices and miss others entirely.

For additional guidance on escalation workflows, Resolve Pay’s guide to chasing unpaid invoices covers practical ways to manage overdue balances while keeping buyer relationships intact.

Step 5: Automate AR Reconciliation

The final operational layer is payment matching. Automated invoice reconciliation confirms that incoming payments are correctly applied to open invoices and reflected in your accounting system.

Without automation, reconciliation is manual: a buyer pays by ACH, wire, check, or card, the deposit appears in your bank account, and someone matches that payment to the invoice. That creates avoidable work and increases the risk of incorrect payment application.

Three ways to improve reconciliation

Shopify payments and ACH workflows

Shopify’s B2B feature set includes ACH payments in the United States, which can help tie payment activity more directly to the order workflow when buyers pay through supported Shopify payment flows.

Accounting and ERP sync

Invoice and payment data should flow into your accounting system or ERP so finance teams can close invoices, track aging, and prepare accurate reports. If invoice data remains separate from the ledger, reconciliation work usually moves into spreadsheets.

Resolve Pay AR automation

Resolve Pay’s B2B payments platform brings credit, net terms, payment collection, invoicing workflows, and reconciliation into a single B2B payments layer. Resolve Pay supports payment workflows across ACH, wire, credit card, and check through a branded payment portal, while helping merchants automate receivables and reduce manual input.

Step 6: Close the Cash Flow Gap with Net Terms Financing

Steps 1 through 5 automate the operational workflow of B2B invoicing on Shopify. They help you create invoices, deliver them, send reminders, and reconcile payments. But they do not fully solve the cash flow gap created by net terms.

If a buyer receives net 30, net 60, or net 90, you may still wait weeks or months for payment even when the invoice workflow is automated. That is where Resolve Pay’s net terms and advance pay model can help.

Resolve Pay’s Shopify integration works as a credit and AR layer on top of your B2B operation:

  • The buyer places an order through your Shopify store.
  • Resolve Pay helps assess the buyer for net terms.
  • Approved buyers can receive terms that match your program.
  • Resolve Pay can advance payment on approved invoices.
  • The buyer pays Resolve Pay according to their terms.
  • Resolve Pay supports collections and payment workflows through a non-recourse structure.

This model helps merchants offer flexible terms without turning the finance team into a full-time credit and collections department. Resolve Pay’s net terms ecommerce solution is built for sellers that want to embed net terms into B2B ecommerce while protecting cash flow.

Choosing Your Shopify B2B Invoice Automation Stack

Not every B2B merchant needs the same level of automation. The right stack depends on order volume, buyer base, accounting complexity, and whether the main challenge is operational workload or cash flow timing.

Use a manual workflow when

You have a small number of established B2B buyers, predictable payment behavior, and a finance team that can comfortably manage invoices and follow-ups without missing deadlines.

Use invoice automation when

Your main pain point is invoice creation and delivery. This is often the right intermediate step when buyers need formal PDF invoices, PO references, and consistent AP delivery, but your credit and collections process is still manageable.

Use Resolve Pay when

You want to offer net terms at scale, automate buyer credit decisions, reduce manual AR work, and improve cash timing with advance pay on approved invoices. Resolve Pay is built for B2B merchants that want a connected workflow across credit, invoicing, payment reminders, collections, reconciliation, and embedded payments.

5 Common Mistakes When Automating B2B Invoicing on Shopify

1. Extending Credit Before a Buyer Assessment

Shopify makes it easy to assign terms to a company location, but the credit decision still matters. Before activating terms, verify the buyer, review payment history where available, and define a credit limit that fits the relationship.

Resolve Pay can support this process through business credit checks and buyer assessment workflows that help merchants evaluate accounts before extending payment flexibility.

2. Using Order Confirmations as the Only Invoice Workflow

Order confirmations are useful transactional messages, but many B2B buyers need formal invoices for AP processing. Configure an invoice workflow that includes invoice numbers, PO references, due dates, payment instructions, and tax details.

3. Offering the Same Terms to Every Buyer

Not every buyer should receive the same credit terms. New accounts may need payment at checkout or shorter terms, while established accounts may qualify for longer terms after positive payment history. Shopify’s location-level structure helps merchants apply this policy with more control.

4. Skipping Accounting or ERP Integration

If Shopify invoice data stays separate from accounting records, reconciliation becomes a manual process. Connect your invoicing and payment workflow to your accounting or ERP system early so open invoices, payments, and credit notes stay aligned.

Resolve Pay’s integration platform is designed to connect B2B ecommerce, ERP, accounting, credit, and payment workflows so finance teams can avoid duplicate entry.

5. No Defined Escalation Path for Overdue Accounts

Automated reminders handle part of the process, but finance teams still need a policy for overdue accounts. Define what happens at each threshold: when the account manager is notified, when terms are paused, when a collections review begins, and how future orders are handled.

Advanced Tips

Use Shopify Flow to flag exceptions

Shopify Flow can help route exceptions, tag buyers, trigger internal alerts, and support B2B order logic. Use it to notify finance when an order needs review before fulfillment.

Capture PO numbers consistently

Many B2B buyers require PO numbers for invoice approval. Make sure your checkout and invoice workflow capture and display the PO number clearly.

Segment buyers by credit profile

Create buyer segments based on payment history, credit assessment, order volume, and account importance. Use those segments to guide payment terms, reminder cadence, and escalation workflows.

Review credit limits regularly

Buyer creditworthiness can change. Review limits periodically and after major changes in order volume or payment behavior.

Sync invoice status to account management workflows

Sales and account teams should know when a customer has overdue invoices before encouraging additional orders. Syncing invoice aging into CRM or account workflows helps teams manage relationships with better context.

Final Verdict

Automating B2B invoicing on Shopify is not just about sending PDF invoices faster. A reliable workflow connects company accounts, payment terms, invoice delivery, reminders, reconciliation, buyer credit decisions, and cash flow management.

Shopify gives merchants a stronger B2B foundation through company accounts, company locations, payment terms, PO numbers, ACH payments, payment reminders, and workflow automation. That foundation works best when it is connected to a receivables process that finance teams can trust.

For merchants that only need invoice delivery, an invoice automation workflow may be enough. For merchants extending net terms at scale, the bigger opportunity is to automate the full credit-to-cash process. Resolve Pay helps B2B sellers offer net terms, assess buyers, automate receivables, collect payments, reconcile invoice activity, and receive advance pay on approved invoices through a non-recourse model.

That makes Resolve Pay a strong fit for Shopify B2B merchants that want to grow sales with flexible payment terms while protecting working capital and reducing manual AR work.

Frequently Asked Questions

What does it mean to automate B2B invoicing on Shopify?

Automating B2B invoicing on Shopify means setting up workflows that create invoices, deliver them to the right buyer contact, send payment reminders, and reconcile payments with minimal manual work. For B2B merchants, this usually includes company accounts, payment terms, PO capture, invoice generation, accounting sync, and AR follow-up.

Does Shopify support net terms for B2B orders?

Yes. Shopify’s B2B documentation includes payment terms for company locations, and its B2B plan feature table lists net terms across paid plans. Merchants should still verify the exact features and limits available on their plan before implementation.

How does Resolve Pay work with Shopify B2B invoicing?

Resolve Pay adds a B2B payments and AR automation layer around Shopify. It helps merchants offer net terms, assess buyer credit, automate invoice and payment workflows, support collections, reconcile receivables, and receive advance pay on approved invoices.

Do I still need invoice automation if I use Shopify payment terms?

Yes. Payment terms define when a buyer is expected to pay, while invoice automation controls how the invoice is generated, delivered, followed up, and reconciled. A complete B2B workflow usually needs both.

How can Shopify merchants reduce late B2B payments?

Start with buyer credit checks, assign terms by account quality, send structured reminders before and after the due date, and define escalation rules for overdue balances. Resolve Pay can also help reduce late-payment exposure by managing credit, collections, and advance pay through a non-recourse net terms model.
