Short answer: they solve different problems. A2X is the most accurate posting of Amazon, Shopify, Walmart, and TikTok Shop settlements into Xero or QuickBooks. Syntheka governs the recovery action — who sees a discrepancy, who verifies it, who files the claim. Many teams will use both. Here is the full comparison, including where A2X wins.
| Dimension | A2X | Syntheka |
|---|---|---|
| Core question | “Post my marketplace settlements into Xero or QuickBooks accurately.” | “Find money the marketplace has left on the table, and govern every recovery action with verification and human approval.” |
| Marketplace coverage | Amazon, Shopify, Walmart, TikTok Shop, eBay, Etsy (depending on plan) | Amazon SP-API + Shopify + bank statement ingestion (Walmart + TikTok Shop in pilot queue) |
| Accounting integration | Xero, QuickBooks Online (native) | Multi-channel reconciliation output + audit trail; not an accounting tool |
| Reimbursement recovery | Not in scope (separate category: Getida / Refunds Manager / etc.) | In scope: discrepancy detection + verified recovery + customer-approved filing |
| Chargeback counter-attack | Not in scope (separate category: Chargeflow / Midigator) | In scope: multi-channel chargeback counter-attack with verification |
| Verification model | Settlement posting is automated | Customer-verified per claim (Zendesk verified mode per W2); never billed on assumed resolution |
| Pricing model | Published tiered ($19-$249/mo depending on GMV band and add-ons) | Published fixed-tier ($500/$2,000/Enterprise) + outcome-aligned option per verified-recovery-claim |
| Self-hosting | SaaS only | Self-hosted or private cloud; data stays in your perimeter |

A2X is the most accurate way to post Amazon, Shopify, Walmart, and TikTok Shop settlements into Xero or QuickBooks Online. If your pain is “my books don't reconcile to my bank,” A2X is the right starting point.
A2X is built for the e-commerce accountant who needs clean, reconciled books at month-end. The accountant workflow is the design center.
A2X has years of edge cases handled (refunds, returns, marketplace fees, multi-currency, multi-region). Syntheka is younger; A2X is the more battle-tested option for pure settlement accounting.
Syntheka's approval DAG governs the recovery action itself: who sees the discrepancy, who verifies it, who files the claim. A2X does not do this; recovery is a separate category.
Syntheka's multi-channel chargeback counter-attack (Amazon + Shopify + Walmart + TikTok Shop) is unique. Single-channel chargeback vendors exist (Chargeflow etc.); multi-channel counter-attack with explicit verification is the Syntheka positioning.
Every claim is customer-verified before invoice (Zendesk verified mode per W2). No billed-on-assumed-resolution; no surprise charges. This is the alignment with your team's time.
If you are choosing between Syntheka and A2X, the most common outcome is: keep A2X for settlement accounting and add Syntheka for the recovery action with verification. The pilot is built around that outcome.
