Mind the gap.UK B2B e-invoicing becomes mandatory in April 2029. Making Tax Digital is already here.What that means for you

Features

Everything an accounting system has to do. Plus the network work.

Aratun is a full accounting package and an ERP on the same ledger, in the browser and on the phone. Below is what each part actually does — not a list of nouns.

The core

Where most of the daily work is, and where we are strongest.

The bookkeeping, done as it happens.

Financial core

Income and expense tracking

BrowserPhone app

Every pound in and out, coded to the right account on the day it happens, not in a panic before the deadline.

  • Income and expenses on one running ledger
  • Coded to the local chart of accounts automatically
  • Cash and bank side by side
  • Receipts attached to the posting, permanently
  • Categories you can report on, not just labels
  • The figure you owe, visible all month

AI scan-to-book

BrowserPhone app

Photograph it and it is booked. Not read into a queue for someone to key in — booked, with its lines, to the right account.

  • Receipts, invoices, bank statements and till reports
  • Line level: quantities, rates, discounts and deposits
  • The account code decided on arrival, per country chart
  • Forward an email to your inbox address and it posts itself
  • Corrections teach it — the same supplier is right next time
  • The original image kept beside the posting, unchanged

Invoicing and quotes

BrowserPhone app

Quote for the work, turn the quote into an invoice, send it with a way to pay, and let it chase itself.

  • A quote that becomes an invoice without retyping
  • Your own template, logo and payment terms
  • A payment link on the invoice itself
  • Reminders that go out on a schedule you set
  • Credit notes that keep the original reference
  • Recurring invoices for retainers and rent

Bills and purchases

BrowserPhone app

Supplier invoices, purchase orders and payment runs, with approval before any money moves.

  • Purchase orders raised before the spend
  • Three-way match: order, delivery, invoice
  • Approval rules by amount and by person
  • Batch payment runs on one approval
  • What is due and what is overdue, per supplier
  • Supplier statements reconciled against your ledger

Bank feeds and reconciliation

Browser

A live feed from the bank, matched against the ledger, with the reasoning shown for every suggestion.

  • Open Banking feed, refreshed daily
  • Statement import: CSV, OFX, QIF and MT940
  • Suggested matches with the reason attached
  • Rules you write once and never write again
  • A reconciled state you can trust, per account
  • Unmatched items listed, never hidden

Customers and suppliers

BrowserPhone app

One card per trading partner: every document, every payment, the balance today.

  • Every document and payment in one history
  • Statements you can send from the card
  • Credit limits and payment terms
  • Smart lists by balance, age or activity
  • Registered company details, checked
  • The Peppol participant identifier held on the card

Reports

BrowserPhone app

Profit and loss, balance sheet, trial balance and ageing — and any figure opens the document behind it.

  • Profit and loss, balance sheet, trial balance
  • Aged debtors and aged creditors
  • Drill from any figure to the source document
  • Period, quarter and year comparisons
  • Cash-flow forecast from the open items
  • Export to PDF, Excel or CSV

Multi-currency

Browser

Invoice, pay and report in more than one currency, with the differences posted for you.

  • Daily rates, or the rate you choose
  • Realised and unrealised differences posted automatically
  • A reporting currency per company
  • Gains and losses on the profit and loss
  • Bank accounts held in their own currency

Budgets

Browser

Set a budget by account and watch the variance while the month is still fixable.

  • Budget by account, by month
  • Budget against actual, updated live
  • Several scenarios side by side
  • Variance shown on the profit and loss
  • Last year as a starting point

Reconciliation

The month closes when the bank agrees with the ledger.

A payment against an invoice, an invoice against an order, a statement against a supplier account. Aratun proposes each match and shows its reasoning, so you accept a decision rather than make one from nothing.

Rules you write once
A rule you accept this month holds for the next one.
Variance in front of you
Where the figures disagree, the difference is the first thing on screen.
