Stop checking the invoices that were right.
Most invoices are correct. Your team checks all of them anyway, because the few that are not cost money. GUIDSE unifies invoices, purchase orders, contracts and bank data, masks personal and banking details, and lets AI agents do the matching, so your controllers and accountants handle only the exceptions, with the evidence already gathered.
Where the work gets stuck
-
Matching by hand
Received invoices are compared with orders and contracts one by one.
-
Month-end crunch
Accruals, reconciliations and intercompany differences pile up in the last three days.
-
Client documents in every format
Accounting firms receive bank statements, receipts and payslips by email, upload and post.
-
New e-invoicing rules
Structured Peppol invoices are now mandatory for Belgian domestic B2B, and the processes around them still need to change.
Processes GUIDSE runs
-
Accounting Exception Management
Reconciles received invoices (Peppol UBL, PDF) against purchase orders, contracts and ERP data and routes only price, quantity, VAT or duplicate exceptions.
-
Bank-to-ledger reconciliation
Matches bank statement lines (CODA, CAMT.053) with open items and proposes the booking for approval.
-
Client document intake for accounting firms
Collects, classifies and pre-codes client documents per file, and flags what is missing before the VAT return deadline.
-
Closing and reporting templates
Fills closing checklists, VAT working papers and management-report templates from the governed dataset.
-
Revenue Leakage Assessment
Compares contracts, price lists and issued invoices for unbilled items, missed indexation and wrong discounts.
The same six steps in every sector.
The difference is in the U: your data is unified and masked before any agent acts on it.
-
Gather
Connect the ERP or accounting package, the Peppol access point, bank feeds and the client mailbox.
-
Unify
One ledger-ready dataset. IBANs, national registration numbers and employee data are masked before any agent reads them.
-
Interpret
Agents read invoices and contracts and compare them with orders.
-
Decide
Controllers or file managers approve. Every booking proposal has an audit log entry.
-
Systematize
Daily matching and a monthly closing calendar, with budgets per process.
-
Evolve
New entities, new clients and new tax rules are added as configuration.
Data and privacy
Invoices and bank files carry IBANs, salaries and personal data protected under GDPR. GUIDSE masks those fields before any AI provider sees them, runs AI usage on your own provider key, and lets you export everything at any time.
