Invoice approvals and payments should be predictable. But for many finance teams, they still mean chasing stakeholders, re-keying invoice data into an ERP, and rushing payment runs at the end of the month.
The workload is increasing. In 2025, 63% of finance professionals said they spend more than 10 hours per week on invoice processing, and 66% still manually enter invoice data into their ERP (IFOL Accounts Payable Automation Trends 2025).
If you’re evaluating AP tools, the goal is not just “going paperless”. It’s building an invoice-to-payment workflow that scales, improves control, and reduces risk.
Below, we cover what to look for, which tools fit which use cases, and how to choose without turning it into a six-month project.
Where invoice approvals and payments typically break down
Most teams have moved from paper to PDFs, but not from manual work to true automation. A PDF in an inbox still triggers the same chain of tasks: capture, coding, approvals, reconciliation, and payment.
The main bottlenecks are consistent across industries:
Manual effort stays high: manual processing is expensive, with one benchmark putting the manual cost per invoice at around USD 9.40 (Quadient AP automation statistics 2025).
Cycle times drag: best-in-class teams process invoices in 3.1 days vs 17.4 days for others, which affects supplier relationships, late fees, and the ability to capture early payment discounts (Accounts Payable Metrics that Matter).
Visibility arrives too late: when finance only sees spend at invoice receipt, budgets become reactive, and “maverick spend” becomes harder to prevent (IFOL Accounts Payable Automation Trends 2025).
Streamlining means fewer touchpoints, faster routing, and clearer control before a bill becomes a problem.
What to look for in invoice approval and payment software
The “best” tool depends on your size, geography, and payment complexity. But most finance teams should prioritise the same six capability areas.
Capture and coding that reduces touchpoints
At minimum, look for OCR-based invoice capture and configurable coding rules (GL accounts, cost centres, VAT). A good baseline test is whether the tool can get you closer to low-touch processing for repeat suppliers and predictable invoice formats (Quadient AP automation statistics 2025).
Approval workflows that match real governance
The approval engine should support:
conditional rules (amount, department, vendor, entity)
clear audit trails
fast exception handling (missing PO, mismatches, policy violations)
If approvals live in email, you lose speed and traceability. If approvals are too rigid, you create workarounds.
Matching and controls for purchase orders
If you use purchase orders, prioritise two-way or three-way matching and the ability to route mismatches to the right owner. This is one of the quickest ways to improve accuracy and reduce disputes.
Payments that are trackable and reliable
For payment execution, check for supplier onboarding, payment status tracking, and multi-currency support if you operate internationally. The most streamlined payment workflows are the ones AP does not have to manually explain to the rest of the business.
Integrations that prevent new reconciliation work
Automation only works if it integrates cleanly with your accounting system. Validate exports, field mapping, entity handling, and how vendor master data is managed. Many implementations fail because the tool adds a second set of books.
Compliance readiness, especially in Europe
If you have EU entities, validate the vendor’s roadmap for e-invoicing compliance. Timelines are tightening, including Belgium’s mandatory B2B e-invoicing from 1 January 2026, and Germany’s shift to e-invoicing as a standard method from 2025.
The best tools for streamlining invoice approvals and payments
Here are tools that regularly appear in AP automation evaluations, along with the “best for” context that matters in practice.
Spendesk
Spendesk is a complete spend management platform that combines invoice automation with approvals, budget visibility, and payment methods in one place. It’s a strong fit for teams that want unified invoice-to-payment, plus control over wider company spend, with less fragmentation across cards, expenses, and subscriptions.
Best for: growing SMEs and mid-market teams that want invoices, approvals, and broader spend controls in a single system, particularly across multiple entities.
Proof points: browse outcomes and stories from existing customers.
Tipalti
Tipalti is often shortlisted when payments are the hard part, especially for organisations paying large supplier bases across countries. If you operate in a mass payout model, it can be a strong fit.
Best for: complex, high-volume AP with global payment needs.
Less ideal for: teams primarily seeking better visibility and approvals across everyday operational spend.
BILL
BILL (Bill.com) is frequently positioned as a user-friendly entry point for small and medium businesses that need basic invoice approvals and vendor payments. Many comparisons also flag that teams can outgrow simpler workflows as governance and volume increase (Stampli invoice processing software overview).
Best for: smaller finance teams that want to digitise AP quickly.
Watch-outs: workflow flexibility and cost predictability as volume scales.
Payhawk, Ramp, and Airbase
If you’re looking at spend management platforms for smaller businesses rather than larger organisation solutions, these names come up often. In Europe, Payhawk is commonly evaluated alongside Spendesk (Spendesk vs Payhawk comparison). In the US, Ramp and Airbase are often considered by teams that want card-first controls plus AP workflows, especially with a US-centric accounting and compliance setup.
The decision here usually comes down to geography, depth of invoicing features, and how closely the tool matches your approval and entity complexity.
How to choose and roll out the right tool
Start with a simple scoping exercise: invoice volume, approval complexity, payment complexity, and entity structure. Then roll out in stages.
One practical method is to separate suppliers into “personas” and tailor workflows accordingly, a best practice highlighted in AP automation guidance:
Strategic, high-value suppliers: tighter approvals and matching
Recurring suppliers: aim for the most automation
Long-tail, one-off spend: reduce invoice volume where appropriate by using controlled payment methods such as virtual cards when it fits your policy
Finally, measure outcomes with a few clear metrics: cycle time, cost per invoice, and touchless processing rate. Benchmarks show the gap between average and high-performing teams is substantial, especially on cycle time.
Trends to factor in for 2026
Two changes are shaping tool choices right now:
Regulation and e-invoicing mandates in Europe, which can quickly turn “optional” features into requirements (Moody’s EU e-invoicing directive digest).
AI that goes beyond OCR, with analysts highlighting “agentic” capabilities as the next differentiator for exception handling and fraud prevention. Check out Spendesk’s AI Hub.

Conclusion
The best tools for streamlining invoice approvals and payments reduce manual touchpoints, speed up approvals without losing governance, and make payment status easy to track. The right fit depends on your organisation’s “invoice DNA”, but the evaluation criteria are consistent: automation depth, workflow flexibility, integrations, and compliance readiness.
