Which customers still owe us for invoices that fell due in September?

Claude Answer · Sage Accounting

Three customers still owe £18,450 on September invoices. Harlow Interiors accounts for about half of it, on an invoice due 4 Sep.

Harlow Interiors Sales Invoices No Lines £14,600£9,2004 Sep
Brightwell Studio Sales Invoices No Lines £7,900£5,35012 Sep
Penrose Catering Sales Invoices No Lines £4,100£3,90019 Sep

Read from Sales Invoices No Lines, one row per invoice, so totals are not repeated for every invoice line.

Questions Claude can answer from your Sage Accounting data

Sage Accounting, formerly Sage One, is cloud accounting software for small businesses. Dataddo extracts sales and purchase invoices, transactions, journals, ledger accounts, contacts and the product and service catalogues.

Credit check before an order ships

Ask Claude

Is Harlow Interiors over its Credit limit in Contacts? List its Sales Invoices No Lines with an Outstanding amount and Due date.

Sales wants to ship to an existing customer. The credit controller asks Claude, sees Balance against Credit limit and the open invoices, and decides in the same chat.

Month-end ledger variance note

Ask Claude

Use the dataddo server to compare Journals debits and credits by Journal lines - ledger account name for September and August, and write reports/sage-variance.md.

A finance analyst runs Claude Code next to the reporting scripts, pulls Journals with Ledger Accounts for the Nominal Code, and commits a variance note instead of pasting numbers.

Days to pay by customer

Ask Claude

For Sales Invoices No Lines paid last quarter, how many days passed between Date and Last paid per Contact name, compared with their Credit days?

Before renegotiating payment terms, the controller asks Claude which customers pay later than agreed and brings the ranked list to the credit review.

With vs. without

Sage Accounting in Claude, with and without Dataddo

Without Dataddo With Dataddo Outcome for you
Answering credit questions Someone opens Contacts, filters the invoice list, checks Transactions and pastes three screenshots into the chat before Claude can say anything useful. Claude queries Contacts and Sales Invoices No Lines by field name through the Dataddo Data Access connector and joins them in one answer. Credit decisions in minutes
Invoice versus line rows A line-level export repeats each invoice total on every line, and a model summing that file overstates receivables. The semantic layer describes Sales Invoices No Lines as one row per invoice and Sales Invoices as line detail, so Claude picks the right one. Receivables counted once
Bank and contact details An uploaded contact export carries IBANs, sort codes and emails into the conversation, and you cannot take them back. Untick fields such as Bank account - IBAN or hash them with md5 or xxh3 at the source, so Claude never receives them. Personal data stays out
Finance team access Each person on the team keeps a private export, and two people asking Claude the same question get different numbers. On Claude Team or Enterprise an Owner adds the connector once, and each member signs in with their own Dataddo account. Everyone reads the same ledger
Token consumption Claude spends tokens exploring raw Sage Accounting columns, sampling rows and retrying until it understands the data. Field definitions and relations are supplied up front, so the model skips the exploration and goes straight to the answer. Less tokens per answer
Answer quality Prone to wrong joins, invented fields and numbers that are hard to check. Answers grounded in defined fields. In the Dataddo benchmark, 78.5% of questions were answered correctly, against 65.5% with plain CSV files. Better answers
Datasets

Runs on the schedule you set, for example daily. Every Sage Accounting dataset re-reads a relative date window on each run, so older history needs a one-time full data re-sync.

Benchmark

More right answers. Half the confident mistakes.

We asked 43 pre-registered questions of three real datasets - Google Search Console, HubSpot deals and Google Ads - and delivered the same rows to the same model in four ways. Only the data layer changed.

78.5%

of questions answered correctly - the best of the four delivery methods tested

2x

fewer confidently wrong answers - 14.0% of runs against 24.0% and 26.3%

2.8x

more correct answers on messy CRM data - better on 8 questions, worse on none

Answered correctly All 43 questions - higher is better
Wrong, but stated as fact Share of runs - lower is better

Same model, prompts and rows in every condition; 759 graded runs, ground truth frozen before any run. On Google Search Console alone, documented CSV files did as well as Data to AI™ - the advantage comes from messier data such as HubSpot deals.

FAQ

Sage Accounting and Claude: FAQ

How do I connect Sage Accounting to Claude?

Create a Sage Accounting source in Dataddo with datasets such as Sales Invoices No Lines, Purchase Invoices and Transactions, then attach it to a Claude destination or AI Model. In Claude, add the custom connector Dataddo Data Access with https://headless.dataddo.com/mcp-data and sign in. Claude Code users run claude mcp add instead.

Does Claude read Sage Accounting directly?

No. Dataddo extracts Sage Accounting on your schedule and Claude queries that copy through the Data Access MCP server, using entity and field names. Claude never holds your Sage login.

Why does Claude only see recent Sage invoices?

Every Sage Accounting dataset reads a relative date window on each run and replaces that window. To give Claude older invoices, run a full data re-sync with a wider range once.

Can Claude Code work with Sage Accounting data?

Yes. Add the server with claude mcp add, sign in with /mcp and ask about Sage entities while you work in a repository. Credentials stay in your system keychain.

Can I stop Claude from seeing customer bank details?

Yes. Untick fields such as Bank account - IBAN when you create the source, or hash them with md5 or xxh3. Claude can only query the columns that reach the flow.

Who adds the connector on a Claude Team plan?

An Owner adds Dataddo Data Access once for the organization. Each member then signs in with their own Dataddo account, so finance and sales see only what their account can reach.

Which Sage account should authorize the connection?

One with at least admin-level permissions, from a business in the country you select during authorization. A Sage developer account is not linked to any business and cannot be used.
