Ceendesis Accounting · For Accountants

Your ecommerce clients' books should not require a manual review of 47-line settlement files every fortnight.

Ceendesis Accounting automates Amazon and Shopify settlement posting into Xero — correctly categorised, correctly taxed, and with a full audit trail attached to every invoice. Your clients' books stay current. Your review time drops.

The accountant's problem

Ecommerce clients are high-complexity, high-volume, and chronically behind.

If you work with Amazon and Shopify sellers, the problems are familiar. The settlement file lands in your inbox as a CSV. Amazon adds new fee categories regularly. The client doesn't notice. You do — eventually, when the books don't reconcile.

Amazon fee categories require specialist knowledge.

FBA fees are input-tax recoverable. Marketplace-collected VAT is not your client's output liability. Digital Services Tax is non-deductible. Withheld US tax has no place on a UK return. Get any wrong and the VAT return is wrong.

Every settlement has a different fee mix.

Amazon introduces new charge categories regularly. Your client may not notice. You won't notice until the books don't reconcile or your auto-post pushes them to the wrong account.

Settlement cycles create permanent lag.

Amazon settles every two weeks. Shopify pays weekly. Your clients are always two weeks or more behind — meaning any review you're doing is of historical data, not current state.

Shopify payouts are blended and opaque.

One number lands in the bank. Behind it: 300 orders, refunds, processing fees, chargebacks, and adjustments. Translating that into clean Xero bookkeeping eats hours per client per month.

For accounting practices

What Ceendesis gives you.

1

Audit-ready invoices in Xero, every time.

Every Xero invoice has a CSV audit trail attached: every line item from the original settlement, the mapping applied, the tax type, the amount, and the posting timestamp. When a client or HMRC asks about any line, you open the attachment and the answer is there.

2

Pre-flight validation on every posting.

Six checks run before anything reaches Xero: math, account codes, tax types, mapping completeness, SKU mapping, duplicates. Your client's books contain only postings that passed full validation. Your review starts from a position of trust.

3

Multiple Xero organisations, one Ceendesis account.

Connect multiple Xero tenants. Each client's Amazon and Shopify channels route to their own Xero org. Review all clients from one Ceendesis login — or give each client their own.

4

Mapping export and import.

Set up correct mappings for one client, export as JSON, use it as the starting point for the next client. The taxonomy of Amazon fee types is largely consistent — you shouldn't be mapping from scratch every time.

5

Unknown fee detection before it becomes your problem.

When Amazon introduces a new fee category, Ceendesis flags it immediately — before the settlement auto-posts. Your client receives the alert. The incorrect posting never reaches Xero. You're not cleaning up after the fact.

6

Correct VAT defaults built in.

The default tax codes for Amazon categories are reviewed for UK and EU VAT compliance. FBA fees → INPUT2. Marketplace-collected VAT → ZERORATEDOUTPUT. US withheld tax → NONE. Your clients aren't starting from a blank slate.

Your ecommerce clients' books should be done before you arrive.

Set up Ceendesis for a client once. Their Amazon settlements and Shopify payouts post to Xero automatically from that point on — validated, correctly taxed, with the audit trail attached. You review. You don't reconcile.
