Supplier and client onboarding for e‑invoice adoption

Written by WorkflowMax | Jun 3, 2025 4:16:29 PM

TL;DR: Adopting e‑invoicing can streamline cash flow, reduce administrative errors, and improve compliance but success hinges on effective supplier and client onboarding. For architects, engineers, creatives, and accountants, the key is creating a smooth transition for stakeholders through clear communication and integration with tools like WorkflowMAX. With features like automated invoicing, job costing, and deep integration with Xero or QuickBooks, WorkflowMAX provides a structured environment to make e‑invoicing work seamlessly.

Why E‑Invoice Adoption Matters Now

If you're an architect, engineer, designer, or accountant, you're already familiar with the slow, error-prone nature of manual invoicing. From delayed payments to reconciliation headaches, traditional invoicing methods are increasingly out of step with modern expectations and compliance regulations.

Enter e‑invoice adoption: a transformative solution offering faster payments, lower error rates, and greater visibility. But here’s the catch: switching to e‑invoicing doesn’t just require internal readiness. You need your suppliers and clients on board too. And that’s often where the process hits friction.

Here’s a practical look at the onboarding process, what to expect, and how WorkflowMAX fits into the transition.

Why E‑Invoicing is a Win for Service-Based Firms

Reduced Admin, Improved Accuracy

Manual invoicing leads to issues like duplicated data, lost PDFs, and delayed approvals. E‑invoicing automates the exchange of invoices in a standardised digital format, reducing admin time and improving accuracy.

Faster Payments, Better Cash Flow

Many businesses adopting e‑invoicing see improved Days Sales Outstanding (DSO) due to quicker processing and fewer disputes. For service firms reliant on predictable cash flow, this can be game-changing.

Enhanced Compliance and Audit Trails

With governments in Australia, New Zealand, and the UK tightening compliance regulations (e.g., Peppol standards), e‑invoicing helps ensure that your invoicing practices align with legal expectations.

But while the benefits are clear, the transition involves more than flicking a switch. The real challenge? Supplier and client onboarding.

Friction in Supplier and Client Onboarding

Resistance to Change

Suppliers and clients may be reluctant to shift from PDFs and emails to structured e‑invoice formats especially if they don’t see an immediate benefit or perceive it as a technical burden.

Technology Mismatch

Not all stakeholders are at the same level of digital maturity. While your business might be using integrated job management tools, your client could still be sending Word docs and printing cheques.

Lack of Standardisation

While standards like Peppol aim to unify e‑invoice formats, regional and software-specific variations still lead to inconsistencies especially when working with international stakeholders.

Onboarding Fatigue

If you’re scaling or juggling multiple projects, onboarding suppliers and clients can feel like just another administrative hurdle unless you have a clear, repeatable process.

Best Practices for E‑Invoice Onboarding Success

1. Start with Internal Readiness

Before engaging others, ensure your own systems and workflows are optimised for e‑invoicing:

  • Use job management tools like WorkflowMAX to centralise project data and billing.
  • Integrate with accounting systems like Xero or QuickBooks to streamline the flow of financial data.
  • Set up invoice templates with required metadata (e.g., invoice number, job code, tax info) aligned with Peppol or other standards.

2. Segment Your Suppliers and Clients

Not everyone needs the same approach. Group stakeholders into tiers based on size, digital readiness, and importance to your cash flow.

  • Large clients/suppliers with their own finance teams. Prioritise these for structured onboarding and system integration.
  • SMEs using cloud accounting software. Offer template-based onboarding with links to your preferred e‑invoicing method.
  • Low-volume or low-tech stakeholders. Continue sending PDFs or use portals while gently encouraging future digital adoption.

3. Create Clear Onboarding Kits

A good onboarding experience includes:

  • A simple explanation of why you’re adopting e‑invoicing.
  • Step-by-step instructions tailored to their software.
  • FAQs about privacy, security, and payment timelines.
  • Links to online guides, video tutorials, or contact points.

4. Use Integration-Friendly Tools

The best tools support structured data formats and integrations across your ecosystem.

  • WorkflowMAX integrates directly with Xero and other accounting platforms, pushing job and invoice data directly through your finance pipeline.
  • Export formats in WorkflowMAX make it easy to produce e‑invoices that conform to standard structures.
  • Use automated workflows to minimise manual entry and errors, especially across recurring invoices.

5. Communicate Proactively

Don’t spring e‑invoicing on clients during crunch time. Start the conversation early, and position the change as a shared benefit.

For example:

“We’re adopting e‑invoicing to make your experience faster, more accurate, and more secure. You’ll see fewer errors, and we’ll both save time.”

A monthly newsletter, a client portal update, or a project kickoff call can all be good moments to introduce the topic.

6. Monitor and Optimise the Process

After the initial wave of onboarding:

  • Track adoption rates and segment compliance metrics.
  • Use WorkflowMAX’s reporting tools to see which clients are late on payments and if that correlates with e‑invoicing status.
  • Re-engage laggards with nudges, support, or alternative formats.

This isn’t a one-time exercise. It improves over time as feedback and financial impact become clearer.
