6 Best AP Automation Tools for Microsoft Dynamics GP (2026)

Last updated: 6 November 2026

The best AP automation tools for Microsoft Dynamics GP in 2026 are Kefron AP, Rillion, Stampli, Fidesic, Quadient AP and Tipalti. Because Microsoft ends GP product support on 31 December 2029, the safest choice is a tool that also integrates with Dynamics 365 Business Central. Kefron AP integrates with GP today and connects to Business Central through a direct API, so your AP process moves with you when you migrate.

Dynamics GP has run the finances of thousands of mid-market organisations for decades. Its payables module handles posting and payments well, but invoice capture, coding, matching and approvals still rely heavily on manual work. AP automation fills that gap. The question in 2026 is not only which tool fits GP, but which one will still fit after you leave it.

Dynamics GP AP Automation Tools at a Glance

Why GP's End of Support Changes How You Choose

Microsoft has announced that it will end product support and updates for Dynamics GP on 31 December 2029, with security patches ending on 30 April 2031. After 2029 there will be no product enhancements, regulatory or tax updates, or technical support. Microsoft is directing GP customers towards Dynamics 365 Business Central.

That gives most GP users a migration in the next few years. If you automate AP now with a tool that only works with GP, you will re-implement AP during the ERP move, the point when your finance team has the least capacity to spare. Choosing a tool that already integrates with Business Central means your supplier data, approval rules and invoice history carry across, and AP keeps running through the switch.

6 AP Automation Tools for Microsoft Dynamics GP

1. Kefron AP

Best for: GP users who want high touchless processing now and a direct path to Business Central later.

Kefron AP automates the full invoice cycle for Microsoft Dynamics, from AI invoice capture to coding, 2-way and 3-way PO matching, approvals and posting. It works with GP and other legacy Dynamics systems such as NAV and AX, as well as Dynamics 365.

What sets it apart is the combination of AI extraction with a dedicated Data Assurance Team that validates fields the AI is unsure of. That delivers 99%+ accuracy after validation and 70–90% touchless processing for recurring suppliers. Kefron AP also has a direct API integration with Dynamics 365 Business Central, so the AP process you build on GP moves with you when you migrate.

Key strengths

• AI capture with human data assurance, 99%+ accuracy after validation
• 70–90% touchless processing for recurring suppliers
• 2-way and 3-way PO matching included as standard
• Direct API integration with Dynamics 365 Business Central
• Certified Microsoft Dynamics partner

Worth shortlisting when: You want to cut manual AP work on GP now without having to replace your AP tool when you move to Business Central.

2. Rillion

Best for: Teams with high invoice volumes and complex PO matching who want GP to remain the system of record.

Rillion reads invoices from paper, PDF and XML, matches them to purchase orders and goods receipts, and codes non-PO invoices using rules and optional AI. Approved invoices are pushed into GP's Payables Management for posting, and payment outcomes sync back.

Key strengths

• 2-way and 3-way matching against GP purchasing data
• Rules-based and AI coding for non-PO invoices
• Payments through GP or Rillion Pay

Worth shortlisting when: PO matching volume is your biggest manual workload.

3. Stampli

Best for: Teams whose main problem is chasing approvals and answering questions about invoices.

Stampli connects to on-premises GP environments through its Stampli Bridge. Coding, posting details, approvals and conversations stay linked to each GP transaction, and approved invoices and payment records are sent back to GP.

Key strengths

• Invoice-level collaboration and approval history
• 2-way and 3-way matching with supported PO data
• Connects to on-premises GP

Worth shortlisting when: Approval delays, not data entry, are holding up your invoices. For more options, see our Stampli alternatives comparison.

4. Fidesic

Best for: Organisations that want a vendor focused only on the Microsoft Dynamics ecosystem.

Fidesic builds its AP automation specifically for Dynamics GP and Business Central. It covers AI invoice capture, approval workflows that follow your delegated authority, and check and ACH payments.

Key strengths

• Built specifically for GP and Business Central
• Approval routing by branch or location
• Integrated check and ACH payments

Worth shortlisting when: You run only Microsoft ERPs and want a Dynamics specialist.

5. Quadient AP

Best for: Multi-entity organisations that want centralised AP visibility across GP companies.

Quadient AP syncs with GP manually or on a schedule you set, bringing vendor and accounting data in and sending approved invoices back. It offers a multi-entity dashboard and lets you pay from GP or from Quadient AP.

Key strengths

• Manual or scheduled GP sync
• Multi-entity AP dashboard
• Payments from GP or Quadient AP

Worth shortlisting when: You manage several GP companies and need one view of payables.

6. Tipalti

Best for: GP users with large international supplier bases.

Tipalti connects to GP to sync invoice, supplier, payment and reconciliation data. Its strength is global payments and supplier tax compliance, and the GP integration is delivered through Tipalti's professional services team.

Key strengths

• Global supplier payments and tax compliance
• Multi-entity workflows
• Real-time payment sync to GP sub-ledgers

Worth shortlisting when: Cross-border payments are a bigger issue than invoice processing. See our Tipalti alternatives guide for more.

What to Ask Any Vendor Before You Buy

1. Does the integration work with Business Central today? Ask for a live Business Central customer reference, not a roadmap slide.
2. Which GP version and hosting setup is supported? Some integrations support only on-premises GP.
3. What syncs, and in which direction? Check supplier records, GL codes, POs, receipts, invoices and payment status.
4. Can invoice images and approval history be exported? You need your audit trail when you change ERP or vendor.
5. What touchless rate is realistic for our invoices? Ask for a figure based on your own suppliers, not a headline average.

In Conclusion

Any of these tools can take manual work out of AP on Dynamics GP. With Microsoft ending GP support in 2029, the bigger risk is automating AP twice. Kefron AP integrates with GP now and with Business Central through a direct API, combining AI capture and human data assurance to reach 70–90% touchless processing for recurring suppliers.
