Stampli vs Ottimate: Accounts Payable Automation Compared

Stampli vs Ottimate: the short answer

For most US finance teams in 2026, Stampli is the better fit when your problem is general accounts payable across a business: capturing invoices, routing approvals through an on-invoice thread, and connecting to your ERP without a long rollout. Ottimate, formerly Plate IQ, is the better fit when you run restaurants, hotels, franchises, or food and beverage operations with high invoice volume and dense line items across many locations. Both are genuine AI-powered AP automation platforms; the decision turns on your industry, your invoice shape, and how you pay vendors.

Where Stampli is strong

Stampli centers everything on the invoice. Its AI assistant captures header and line data, learns your coding, and routes the bill for approval, while approvers, coders, and AP staff keep every comment and question in one thread attached to that invoice. That on-invoice collaboration hub is the feature teams remember, because it cuts the email back-and-forth that usually stalls approvals and it leaves a clean audit trail. It is the same problem every invoice approval software tries to solve, handled inside the invoice rather than around it. Stampli connects to more than 70 ERPs and accounting systems with no custom development, and mid-market teams typically go live in weeks rather than quarters. Pricing is a custom quote scoped to invoice volume, users, and the ERP you connect.

Where Ottimate is strong

Ottimate earned its reputation on the hardest invoices in business: dense, multi-page restaurant and distributor bills with dozens of line items. Built as Plate IQ for the restaurant industry and rebranded Ottimate in 2024, it captures invoices down to the line item, codes them to the right GL account and location, verifies them with two or three-way PO matching, and runs them through multi-step approval workflows. Getting GL coding in accounts payable right at the line level across many locations is the hard part it was built for. It pays vendors by check, ACH, and virtual card, and it leans hard into cashback rebates earned on card payments. For multi-location operators who want location-aware coding and rebate economics on spend they already make, that combination is hard to match.

Pricing and total cost

Neither vendor lists public pricing, so both require a sales conversation. Stampli quotes custom by invoice volume, users, and integrations, and positions on transparent pricing without locked features. Ottimate also quotes custom, but it folds unlimited vendor payments into a flat monthly cost and offsets part of that with virtual-card cashback. The practical advice is the same for both: get a quote scoped to your real volume, and for Ottimate, estimate the cashback you would actually earn given how many of your vendors accept cards. If most of your spend leaves by ACH or check, that rebate is modest, and you should compare the two on subscription cost and workflow fit instead.

Invoice capture, coding, and matching

Both platforms use AI to read invoices and code them, and both support two and three-way matching against purchase orders and receipts. The difference is at the extremes. On standard one to ten line invoices, capture accuracy is comparable. On a 60-line food distributor invoice spread across multiple locations, Ottimate's line-item engine was purpose-built for that job and tends to need less manual cleanup. If your AP volume is dominated by that kind of invoice, weight capture accuracy heavily in the trial.

Payments and rebates

Stampli pays vendors through Stampli Direct Pay and the Stampli Card, covering ACH, check, and card inside the same platform that captured and approved the invoice. Ottimate pays by check, ACH, and virtual card and markets the cashback you earn on card payments. Both keep payment tied to the approved invoice, which is the control that actually prevents duplicate and out-of-band payments. The deciding factor here is rebate economics: how much of your vendor spend can realistically move to virtual cards.

Which should you choose?

Choose Stampli if you run general business AP and want enterprise-grade automation, broad ERP coverage, and on-invoice collaboration without a long implementation. If your real need is one system for the whole function rather than a head-to-head winner, start from accounts payable management software. For other contenders, compare the best AP automation software, or see how Stampli fares against an enterprise-scale rival in Stampli vs Medius or against a procurement suite in Stampli vs Coupa. Choose Ottimate if you operate in restaurants, hospitality, or multi-location food and beverage and want line-item capture, location-aware coding, and virtual-card rebates built for that world.
