The AP Automation Buyer's Guide: What to Look For

By Vaibhav Rane, Founder, Cresolv One

Every AP automation vendor's homepage looks similar: invoice capture, approvals, ERP posting, some percentage promising faster processing. The differences that actually matter show up once you're past the demo and into your real invoice volume — the messy 30-40% that doesn't match perfectly on the first pass. This guide is a framework for evaluating any AP automation platform, not just ours.

What to evaluate before you choose a platform

  • Does it do 3-way matching, or something short of it? Matching an invoice against the PO is a start. Matching against the PO and the GRN catches the far more common problem: goods received don't match what was ordered. If a vendor can't explain their GRN-matching logic clearly, ask why.
  • Is GST and TDS validation built in, or bolted on? For Indian operations, tax compliance checks that happen after posting are checks that happen too late. Ask whether ITC eligibility, GSTIN validation, and TDS applicability are checked before an invoice is approved, not after.
  • What actually happens to exceptions? Every platform automates the clean invoices well. The real test is the other 30-40% — a price mismatch, a missing GRN, an unrecognized vendor. Does the system route these for fast resolution with context, or does it just dump them in a queue that becomes someone's full-time job?
  • Does it post directly into your ERP, or hand you a file to re-import? "Integration" means different things to different vendors. Ask specifically whether posting to SAP, Oracle, Tally, or Dynamics happens automatically, or whether someone still needs to manually push a batch.
  • Can vendors see their own invoice and payment status? If vendors still have to call or email your AP team to ask "did you get my invoice" or "when will I be paid," a large share of your team's time is being spent answering questions a portal should answer automatically.
  • Is SLA and bottleneck visibility live, or a monthly report? A control tower that only tells you where things stood last month doesn't help you fix a stuck approval today.

Questions worth asking any vendor

  • "Walk me through what happens to an invoice that doesn't match the PO or GRN — not the happy path, the exception path."
  • "Which ERPs do you actually post to natively, and which ones need a middleware layer or manual export?"
  • "What tax and compliance checks run automatically, and which ones are still on my team to catch?"
  • "What's your average time from invoice receipt to fully posted, across your real customer base, not your best case?"

Where Cresolv One fits

Cresolv One's AP Automation runs 3-way matching against PO and GRN with configurable tolerance rules, checks GST and TDS compliance as part of the workflow rather than after it, and posts directly into SAP, Oracle, Tally, or Dynamics. Vendors get their own portal for invoice submission and payment tracking, and AP teams get a live control tower for SLA and bottleneck visibility, not a report that arrives after the fact.

If a vendor can't answer these questions clearly in a first call, that's worth noting before you get further into the evaluation. See our AP Automation platform.
