Pricing — per business, not per channel.
A2X charges separately per channel. Amazon EU + Shopify on their Standard plan = $158/month. Add Amazon NA = $237/month. Ceendesis charges once for your business — all channels included. The cheapest A2X plan ($29/mo) also doesn't include COGS tracking — Ceendesis includes it on every plan.
2
Three posting modes vs two.
A2X offers Summary and SKU. Ceendesis adds Product Type — define custom SKU groupings using regex pattern rules and post one Xero line per category. Essential for sellers with 200+ SKU variants who want category-level analysis without 200 invoice lines. No equivalent feature in A2X.
3
Per-order Shopify posting.
A2X posts Shopify settlements as a single summary invoice per payout. Ceendesis supports true per-order posting — one Xero invoice per order, with customer matching, SKU line items, discount handling, and payment gateway routing. This is the gap most B2B Shopify sellers run into with A2X and never find a fix for.
4
Per-marketplace overrides within a single Amazon account.
Within a single Amazon EU account (which can cover 18 marketplaces), Ceendesis lets you set different Xero contacts, invoice prefixes, and tax treatments per marketplace. Amazon.co.uk and Amazon.de can route to different Xero entities entirely. A2X applies one setting across the whole seller account.
5
Pre-flight validation on every posting.
A2X attempts the posting and reports errors after. Ceendesis runs six checks before anything touches Xero — math, account codes, tax types, mapping completeness, SKU mapping, duplicate detection. If anything fails, the posting is blocked and you're told exactly what to fix. Nothing incorrect ever reaches Xero.
6
Unknown fee auto-detection.
A2X users in public reviews note: "Amazon constantly adds new classifications so the app does require regular maintenance. You can't set it and forget it." Ceendesis catches new fee types the moment they appear in a settlement, blocks the auto-post, and emails you. You map it once. It stays automated.
7
Audit CSV attached to every Xero invoice.
Every Xero invoice from Ceendesis has a CSV audit trail attached: every line item from the original settlement, every mapping applied, every amount, posting timestamp. A2X doesn't provide this. With Ceendesis, your accountant can verify any line in Xero without requesting additional data exports.
8
Setup time — under an hour vs reported weeks.
Verified A2X user reviews describe onboarding as "horrendous" and taking "many many weeks" — even holding up bank reconciliations during the process. Ceendesis is designed for self-serve setup in under an hour. If you need help, 1:1 support is available on every plan, not gated behind the $159+/mo tier.
