UK Bacs ADDACS / AUDDIS / ARUDD Parser

Import Bacs Direct Debit advice reports and let amendments, cancellations and unpaid returns flow straight onto your local mandates — a pure file-in parser, no Bacs connection required.

What it does

Keep your own register of UK Direct Debit Instructions (DDIs) in Odoo, then upload the Bacs ADDACS (amendments and cancellations), AUDDIS (rejected new instructions) and ARUDD (returned unpaid Direct Debits) advice reports you download from your own Bacs / Bacstel-IP channel. The module parses the report, splits it into per-advice lines, matches each one to a local mandate, and on apply writes the bank's notice onto the mandate so its state follows the amendment, cancellation or unpaid return. It never transmits anything to Bacs.

Report parsing & matching

action_parse decodes the uploaded file across common encodings, detects the report type and format, and reads the Service User Number, service-user name and report date. Each advice line is matched to a bacs.mandate on its payer reference and, as a fallback, on sort code + account number. Stored counters expose advices, cancellations, amendments, matched / unmatched and shape errors for filtering.

Applying advices to mandates

apply_advice updates each matched mandate: an ADDACS amendment rewrites the sort code, account number or payer name and sets the mandate to amended; an ADDACS cancellation closes it; an AUDDIS rejection marks the new-instruction lodgement as rejected; and an ARUDD return records the unpaid collection and cancels the mandate where the reason code implies the mandate is dead.

Feature highlights

  • Local mandate registerbacs.mandate holds the payer, sort code, account number, DDI reference and SUN, with a lifecycle (draft / active / amended / cancelled / rejected) advanced automatically as advices arrive.
  • Reason-code descriptions — each advice carries its Bacs reason code and a human-readable label, stored as the mandate's last reason for quick triage.
  • Unpaid return tracking — ARUDD returns are counted per mandate and the report totals the returned amount in GBP.
  • Per-advice lines — a bacs.advice.line per record captures the reference, old and new bank details, amount, dates, transaction code and amendment / dead-mandate flags.
  • Unmatched surfacing — a stored "has unmatched" flag and a parse/apply log list advices that matched no local mandate so you can act on them.
  • Pure BYOK file workflow — community Accounting only; no Enterprise SEPA / Direct Debit module required and no outbound Bacs connection.

How it works

  1. Record your Direct Debit mandates (payer reference, sort code, account number, SUN) in the Bacs mandates list.
  2. Download the ADDACS / AUDDIS / ARUDD report from your Bacs / Bacstel-IP channel and upload it, then click Parse.
  3. Review the matched and unmatched advices and click Apply to write the bank's notices onto your mandates.

Scope & disclosure

This is a file parser and reconciler only: it does not submit Direct Debit collections, does not connect to Bacs or Bacstel-IP, and includes no banking credentials. You obtain the advice reports through your own Bacs service-user channel. More at pokutsoft.com/.
